Answer:
5^3 = 125 cm^3
Step-by-step explanation:
The Volume of a cube is expressed as: V = s^3 - where s is the side of the cube and V is volume. Since all sides are 5cm long then the volume of the cube is 125 cm^3 OR it could also be expressed as 125 mL (since 1 cm^3 = 1 mL).
(N ‐ 2) × m when n = 5 and m = 9
Answer:
27
Step-by-step explanation:
n=5 and m=9
so it would be (5-2)x9
Distibute 5-2 which is 3 and multiply 3x9=27
so your answer is 27.

Answer: 60%
Step-by-step explanation:
17 + 19= 36
25+ 35= 60
36/60= 0.6

x-4 ; x+2 ; 3x+1 ; ... are the first three terms of a geometric sequence Determine the sequence if x is positive.
Answer:
x = 8
Step-by-step explanation:
This sequence is a geometric sequence.
As it is a geometric sequence, It means that each term multiply by a value that we call that value "a".
So (x-4) × a = (x + 2)
Therefore [tex]\frac{x+2}{x-4} = a[/tex]
And (x+2) × a = (3x+1)
Therefore [tex]\frac{3x+1}{x+2} =a[/tex].
By this we can make a conclusion that [tex]\frac{3x+1}{x+2} =\frac{x+2}{x-4}[/tex].
[tex]\frac{3x+1}{x+2}= \frac{x+2}{x-4}[/tex] [tex](3x + 1) * (x-4) = (x+2) * (x+2)[/tex] [tex]3x^{2} -11x-4=x^{2} +4x+4[/tex] [tex]2x^{2} -15x-8 = 0[/tex] [tex](2x+1) * (x-8) = 0[/tex]In the last part one of the parentheses should be 0.
First we put (2x+1) equal to 0.
[tex]2x+1 = 0[/tex] [tex]2x = -1[/tex] [tex]x = -\frac{1}{2}[/tex]It gives us a negative answer, so this is not our answer.
Now we put (x-8) equal to 0.
[tex]x-8=0[/tex] [tex]x = 8[/tex]This is a positive answer and it is correct.

Answer:
4, 10, 25, 62.5, ...Step-by-step explanation:
Given GP:
x - 4, x + 2, 3x + 1, ...Common ratio is:
(x + 2)/(x - 4) = (3x + 1)/(x + 2)Cross-multiply and solve for positive x:
(x + 2)² = (x - 4)(3x + 1)x² + 4x + 4 = 3x² - 11x - 42x² - 15x - 8 = 0x = (15 + √(15² + 4*2*8))/4x = (15 + 17)/4x = 8The first term is:
8 - 4 = 4The common ratio is:
(8 + 2)/4 = 2.5The nth term is:
aₙ = 4*(2.5)ⁿ ⁻ ¹The sequence is:
4, 10, 25, 62.5, ...use the formula for the area of a trapizoid A=(b₁+b₂/2), where A is area, and b₁ and b₂ are the length of the bases, and h is the height, to answer the question how many square feet of grass are there on a trapizoidal field with a height of 75ft and bases of 125ft and 81ft?
Answer:
7725 ft²Step-by-step explanation:
Use the formula:
A = (b₁ + b₂) h / 2Substitute the values and calculate:
A = (125 + 81)*75/2 = 7725 ft²7725ft²
Answer:
Solution given:
Area =(b₁+b₂)h/2
where A is area, and b₁ and b₂ are the length of the bases, and h is the height
We have
b₁=125ft
b₂=81ft
h=75ft
Now substituting value we get
Area of trapezoid=(125+81)*75/2=7725ft²

solve the equation for x. 1/3 (6x -9) = -33
Answer:
-15
Step-by-step explanation:
Answer:
x=-15Step-by-step explanation:
1/3 (6x -9) = -33
Multiply both sides by 3
3×1/3(6x-9)=3×3
6x-9=-99
Add 9 from both sides
6x-9+9=-99+9
6x=-90
Divide both sides by 6
6x/6=-90/6
x=-15

PLEASE HELPP AND EXPLAIN!!
Answer:
5x + 18
Step-by-step explanation:
This question is very strange, in that, you aren't finding x or how long the sides are. The "missing" side in the directions is the unmarked side.
If you add up all four sides that are labelled you find the x terms add up to 20x, but it is given that the Perimeter is 25x + 8. So the x part of the unmarked side must be 5x.
Then you'll see if you add up all the plain numbers (constants) they add up to -10. But again they told us that the perimeter is 25x + 8. So the constants need to add up to 8. We have to makeup the -10 and also 8 more for a total of 18.
The unlabelled side must be 5x + 18.
Confirm, all the sides added up, Perimeter=
(5x+18)+(4x)+(5x+2)+(5x-4)+(6x-8)
=25x+8
Herbert and Samantha are both driving from Orlando to Miami. Herbert leaves at 9:00 and averages 60 mph (miles per hour) on the way. Samantha leaves at 9:10 and averages 65 mph on the way. The situation is modeled by this system, where x is the number of hours after Samantha leaves and yis the distance each will travel: y = 60x + 10 y = 65x How long after Samantha leaves will she pass Herbert, and how far will they each have traveled?
Answer:
Option BStep-by-step explanation:
At the point they meet, they both travel same distance.
Make the equations same and solve for x:
60x + 10 = 65x65x - 60x = 105x = 10x = 2They will meet after 2 hours.
The distance traveled at the time is:
65*2 = 130 milesCorrect choice is B
Answer:
Option B
Step-by-step explanation:
We first set the two equations equal to each other.
y = 60x + 10
y = 65x
Equal Values Method:
y = y, so:
60x + 10 = 65x
Solve:
60x + 10 = 65x10 = 5xx = 2We can input 2 into either of the original equations
y = 60x + 10y = 60(2) + 10y = 120 + 10y = 130The correct option is [tex]\boxed{\text{B}}[/tex]

Find the value of x that will make A||B
Answer:
x=5
Step-by-step explanation:
9x-40=3x+20
12x=60
x=5
Answer:
x = 10
Step-by-step explanation:
To make A // B, corresponding angles should be congruent.
9x - 40 = 3x + 20
Subtract 3x from both sides
9x - 3x - 40 = 20
6x - 40 = 20
Add 40 to both sides
6x = 20+40
6x = 60
Divide both sides by 6
x = 60/6
x = 10

Drag and drop a number or symbol into each box to correctly complete the solution.
Answer:
x > -1/4
Step-by-step explanation:
-3/5x + 1/5 > 7/20
Subtract 1/5 from each side, you'll have to change 1/5 to 4/20 so they have the same denominator. 7/20 - 4/20 + 3/20
-3/5x > 3/20
Divide each side by -3/5
To divide fractions, you flip the second fraction and then multiply so you would have 3/20 times -5/3.
-3 * 5 = -15
20 * 3 = 60
Answer is -15/60 which simplifies to -1/4
x > -1/4
Creed wanted to know if there was a correlation between number of years of education and income. He collected data and created the scatterplot shown: scatter plot with points loosely scattered going up to the right Determine the closest correlation coefficient (r value) for this data. 0 0. 8 1 −1.
The closest correlation coefficient of the scatter plot with points loosely scattered going up to the right would be: 0.8.
Correlation CoefficientCorrelation coefficient is a measure of the mutual relationship between two variables.Correlation coefficient, r, ranges from 1 to -1.On a scatter plot, if the data points are clustered along the line of best-fit, the correlation coefficient is strong and away from 0, and vice versa, also it is positive if the line of best-fit or trend slopes upwards from left to right, and vice versa.Therefore, the closest correlation coefficient of the scatter plot with points loosely scattered going up to the right would be: 0.8.

-3.1x+7 -7.4x =1.5 x-6 (x-3/2)
Answer:
x = -113/61, or x = -1.852
Step-by-step explanation:
To solve this equation, remove the decimal fractions by multiplying all terms by 10; the result is:
-31x + 70 - 74x = 15x - 6x + 9.
Then -104x + 70 = 9x + 9, or
-113x = -61.
Finally, x = -113/61, or x = -1.852
