what units would express the volume of a right rectangular prism with a length of 8 meters, a width of 10 meters, and a height of 5 meters?
The volume of a right rectangular prism is given by the formula **V = l × w × h**, where **V** is the volume, **l** is the length, **w** is the width, and **h** is the height²³. The units of volume are cubic units, which means that they are the same as the units of length raised to the third power. For example, if the length is measured in meters, then the volume is measured in cubic meters (m³).
In this case, the length is 8 meters, the width is 10 meters, and the height is 5 meters. Therefore, the volume is:
**V = 8 × 10 × 5**
**V = 400 m³**
The units of volume are cubic meters (m³) because the units of length are meters (m).
Answer:
Step-by-step explanation:
The units for the volume of a right rectangular prism are cubic units because it is a measure of three-dimensional space.
In this case, the length, width, and height of the prism are all given in meters. Therefore, the volume of the prism can be expressed in cubic meters (m³).
So the volume of the right rectangular prism with a length of 8 meters, a width of 10 meters, and a height of 5 meters is:
Volume = length x width x height = 8 m x 10 m x 5 m = 400 m³.
Therefore, the volume of the prism is 400 cubic meters (m³).
Radioactive phosphorus decays continuously at the rate of 5% per day. This means that an initial amount of 9 grams of radioactive phosphorus decays t days according to the formula
The formula for the amount of radioactive phosphorus remaining after "t" days is A = 9 × [tex](0.95)^t[/tex]
Radioactive decay is a process by which the nucleus of an unstable atom emits radiation in the form of particles or energy in order to reach a more stable state. In the case of radioactive phosphorus, the nucleus decays by emitting beta particles, which leads to a decrease in the number of radioactive atoms over time.
The amount of radioactive phosphorus remaining after "t" days can be calculated using the formula
A = A₀ × [tex](0.95)^t[/tex]
Where
A0 = initial amount of radioactive phosphorus (9 grams in this case)
A = amount of radioactive phosphorus remaining after "t" days
t = number of days
So, substituting the given values in the formula, we get
A = 9 × [tex](0.95)^t[/tex]

The area of a quarter circle is 0. 785 square miles. What is the quarter circle's radius?
The radius of the quarter circle is 1 mile.
The formula for calculating the area of a circle is given by A = πr², where A is the area of the circle, r is the radius of the circle, and π (pi) is a mathematical constant equal to approximately 3.14.
To find the radius of a quarter circle, we first need to find the area of the circle. Since the area of a quarter circle is given as 0.785 square miles, we can calculate the area of the circle as follows:
Area of circle = 4 × Area of quarter circle
Area of circle = 4 × 0.785 square miles
Area of circle = 3.14 square miles
Now that we know the area of the circle, we can use the formula for the area of a circle to find the radius. We rearrange the formula as follows:
r² = A/π
r² = 3.14/π
r² = 1
r = √1

Angela’s parents have allowed her to watch TV for a maximum of 7 hours each week. She has already watched TV for hours this week. She wants to watch some episodes of her favorite shows that are each of an hour long. How many episodes, x, can Angela watch this week? Sketch the graph of the inequality that represents the maximum amount of episodes she can watch.
If each episode is 30 minutes long (0.5 hours), then Angela can watch up to eight episodes this week.
Angela has already watched a certain number of hours of TV this week, but we don't know how many. Let's call that number "h". We know that her parents allow her to watch a maximum of 7 hours per week, so we can set up an inequality:
h + x ≤ 7
where "x" is the number of additional hours of TV Angela wants to watch, and "≤" means "less than or equal to". We can simplify this inequality by subtracting "h" from both sides:
x ≤ 7 - h
This inequality tells us the maximum number of hours of TV Angela can watch this week, based on how many hours she has already watched. Now we need to figure out how many episodes she can watch, given the length of each episode.
Let's call the length of each episode "e". We know that each episode is "e" hours long, and Angela can watch "x" hours of TV. So the number of episodes she can watch is:
x ÷ e
where "÷" means division. Putting it all together, we get:
Number of episodes = x ÷ e = (7 - h) ÷ e
Now let's sketch the graph of this inequality. We can plot "x" on the horizontal axis and "h" on the vertical axis, and shade in the region where the inequality is true:
[Insert graph here]
The shaded region represents all the possible values of "x" and "h" that satisfy the inequality. For example, if Angela has already watched 3 hours of TV this week (so h = 3), then the maximum number of hours she can watch is:
x ≤ 7 - h = 7 - 3 = 4
And the maximum number of episodes she can watch is:
Number of episodes = (7 - h) ÷ e = 4 ÷ e
So if each episode is 30 minutes long (0.5 hours), then Angela can watch up to:
Number of episodes = 4 ÷ 0.5 = 8
eight episodes this week.

I need the answer and explanation for this geometry problem. (this is not a live quiz, test, or exam question, just to clarify)
The probability of picking a T and an N is 1/81.
The correct option is (B).
From the geometric shape we can see that the total number of different letter is = 9
that are M, A, T, H, I, S, F, U, N
Now T is one of the letter from that 9 letters.
Now if we pick T then the probability of that = 1/9
Therefore, P(T) = 1/9
now we again replace T in previous position before picking the next letter.
Again the total number of letters = 9
Again, N is one of the letter from that 9 letters.
So the probability of picking N = 1/9
Therefore, P(N) = 1/9
The required probability of picking T and N
= probability of picking T followed by picking N
= P(T)*P(N)
= (1/9)*(1/9)
= 1/(9*9)
= 1/81

A bowling ball shaped like a sphere had a diameter of 21. 6 centimeters. Calculate a measurement closest to the volume of the bowling ball iin cubic centimeters
Answer:
5,234 cubic centimeters
Step-by-step explanation:
The volume of a sphere can be calculated using the formula:
V = (4/3)πr^3
where V is the volume, π is pi (approximately 3.14), and r is the radius of the sphere.
Since the diameter of the bowling ball is 21.6 centimeters, the radius is half of that:
r = d/2 = 21.6/2 = 10.8 centimeters
Substituting this value into the formula, we get:
V = (4/3)πr^3 = (4/3)π(10.8)^3 ≈ 5,233.8 cubic centimeters
Rounding this to the nearest whole number, we get a measurement closest to the volume of the bowling ball of 5,234 cubic centimeters.

Graph the line that passes through the coordinates below and determine which statement is true.
(2, 3), (3, 4.5), (4, 6), (6, 9)
To graph the line that passes through the coordinates (2, 3), (3, 4.5), (4, 6), and (6, 9), we can use the slope-intercept form of the equation of a line, which is y = mx + b.
To start, we can find the slope of the line using any two points on the line. Let's use the first and last points:
slope = (change in y) / (change in x) slope = (9 - 3) / (6 - 2) slope = 1.5
Now we can choose any of the four given points and plug in the slope to find the y-intercept, b. Let's use the second point:
4.5 = 1.5(3) + b b = 0.75
So the equation of the line is:
y = 1.5x + 0.75
To graph the line, we can plot the four given points and then connect them with a straight line. Alternatively, we can choose any two values of x and plug them into the equation of the line to find the corresponding values of y, and then plot the resulting points.

As per the given volume, the height of Sofia's pyramid is approximately 4.8 inches.
Sofia's model of the great pyramid has a volume of 90 cubic inches. This means that if we were to fill the pyramid with water, it would hold 90 cubic inches of water.
The formula for the volume of a pyramid is:
Volume = (1/3) x base area x height
In this case, we know that the volume of the pyramid is 90 cubic inches, and the base of the pyramid has a side length of 7.5 inches. We need to find the height of the pyramid.
We can start by plugging in the values we know into the formula for the volume of a pyramid:
90 = (1/3) x base area x height
We know the base has a side length of 7.5 inches, so the base area is:
base area = (7.5)² = 56.25 square inches
Now we can plug in the base area and solve for the height:
90 = (1/3) x 56.25 x height
270 = 56.25 x height
height = 270 / 56.25

the hydrate CoCl2 x XH2O decomposes to CoCl2, whose mass is 53.9% of the hydrate mass. What is the value of X in the hydrate formula?
Answer:
4
Step-by-step explanation:
Let's start by assuming that the initial mass of the hydrate CoCl2 x XH2O is 100 grams. This means that the mass of the anhydrous compound CoCl2 after decomposition is 53.9 grams (since it is 53.9% of the hydrate mass).
The mass of water lost during the decomposition is therefore:
Mass of water lost = Initial mass of hydrate - Mass of anhydrous compound
Mass of water lost = 100 g - 53.9 g
Mass of water lost = 46.1 g
The molar mass of CoCl2 is 129.8 g/mol, and the molar mass of H2O is 18.0 g/mol. Therefore, the molar mass of the hydrate CoCl2 x XH2O is:
Molar mass of hydrate = Molar mass of CoCl2 + Molar mass of H2O × X
Molar mass of hydrate = 129.8 g/mol + 18.0 g/mol × X
We can set up a proportion to solve for X:
Mass of water lost / Molar mass of water = X / Molar mass of hydrate
Plugging in the values we found:
46.1 g / 18.0 g/mol = X / (129.8 g/mol + 18.0 g/mol × X)
Solving for X:
46.1 g / 18.0 g/mol = X / (129.8 g/mol + 18.0 g/mol × X)
2.56 mol = X / (129.8 g/mol + 18.0 g/mol × X)
2.56 mol × (129.8 g/mol + 18.0 g/mol × X) = X
331.968 g/mol × X + 46.368 g/mol × X = X
378.336 g/mol × X = X
X = 4
Therefore, the value of X in the hydrate formula CoCl2 x XH2O is 4, and the formula of the hydrate is CoCl2 x 4H2O.
A box has a base area of 1.9 m2.
The box is placed on the ground and exerts a force of 4.7 kN.
What pressure is the force applied with?
Give your answer in kN/m2 and rounded to 2 dp.
Answer:
The pressure exerted by the box on the ground is given by the force divided by the area of the base. Let's convert the force from kN to N, and the area from m^2 to cm^2, for convenience:
4.7 kN = 4.7 × 10^3 N
1.9 m^2 = 1.9 × 10^4 cm^2
Now we can calculate the pressure:
pressure = force / area
pressure = (4.7 × 10^3 N) / (1.9 × 10^4 cm^2)
pressure ≈ 0.247 kN/m^2
Rounding this to 2 decimal places, we get:
pressure ≈ 0.25 kN/m^2
Therefore, the pressure exerted by the box on the ground is approximately 0.25 kN/m^2.

2 years of tution and college fee: $19,000
Money already in Account = $5,000
If we deposit $100 every month for 5 years we would get $11,000 that is less than $19,000.
If we deposit $200 every month for 5 years qe would get $17,000 which is still less.
If we deposit $300 every month we would get $23,000 which is not less so the correct answer is $300.
Someone please help !!! 60 points ! Find the value of the variable(s).
The arc measure is 110° and the measures in the quadrilateral are x° is 46° and y° is 163°
We have to find the measure of arc x°
We know that the Arcs can be measured in degrees.
The degree of an arc is equal to the measure of the central arc that creates the arc
The central arc measures 110°
So x° = 110°
The complete measure of the quadrilateral is 360 degrees
As x° is equal to 46°
x° =46°
Now let us find y°
46°+46°+105°+y°=360
y°=360-197
y°=163°
Hence, the arc measure is 110° and the measures in the quadrilateral are x° is 46° and y° is 163°

Answer:
Area of sector = (π/4)(7^2)
= 49π/4 square kilometers
= 38.5 square kilometers
Length of arc = (2π)(7)/4
= 7π/2 kilometers
= 11.0 kilometers
A weather report for Eastern Ontario was a 40% probability of snow the next day. What are the odds against it snowing the next day?
Answer:
The odds against it snowing the next day can be found by subtracting the probability of it snowing (40%) from 100% (the total possible outcomes) and then expressing it as a ratio of non-snowing outcomes to snowing outcomes.
100% - 40% = 60%
The odds against it snowing the next day are 60:40 or 3:2 (simplifying the ratio).
