what is the sum of 21 and 5 times a number f is 61
Answer:
f = 8
Step-by-step explanation:
21 + 5f = 61
5f = 61 - 21
f = (61 - 21) / 5
f = 8
Answer:
f = 8
Step-by-step explanation:
"Sum" = addition
"Times" = multiplication
Write an equation to represent this scenario
21 + 5 * f = 61
Multiply 5 by f
21 + 5f = 61
Subtract 21 from both sides of the equation
5f = 40
Divide both sides of the equation by 5
f = 8

The Great Pyramid of Cheops is a square-based pyramid. The base has sides of 230m, and the height is 147m.
Using the same material, what would the height be if you gave the base sides of 240m?
Answer to nearest meter and explained solution please.
Answer:
height = 140.875m
Step-by-step explanation:
Volume of first pyramid= base * height /3 = 230*147/3= 11270
if the base is 240, volume is remain -> height = volume *3 /base
= 11270*3/240 =140.875m
g We are told that the data is representative of the two populations (U.S. males aged 20-29 years and U.S. males aged 75 years), and we will assume that researchers collected random samples. The samples are very large; therefore, the conditions are met for use of the T-test. Using StatCrunch, we find a T-score of 5.3 and a P-value of "< 0.0001." What can we conclude
Answer:
Step-by-step explanation:
With a T-score of 5.3 and a P-value of "< 0.0001." we can conclude that there is sufficient statistical evidence to prove that the data provided is not a representative of the two populations as the p value is less.
Over what interval is the graph of f(x) = -(x + 8)2 – 1 decreasing?
0 (-8, 0)
O (8, 0)
(- 0,8)
(-∞, -8)
Answer:
(-8, infinity)
Step-by-step explanation:
it's the first option on edge
The solution is, : The given function f(x) is decreasing on the interval :
(-8, +∞).
What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
The function is given to be : f(x) = (x + 8)² - 1
To find the interval of decreasing, first find the critical points of the function f(x)
f(x) = (x + 8)² - 1
⇒ f'(x) = 2(x + 8)
Critical Point : x = -8
Now, Intervals are : (-∞ , -8) and (-8, +∞)
For the interval : (-∞ , -8)
f'(x) > 0 ⇒ f(x) is increasing on this interval.
For the interval : (-8, +∞)
f'(x) < 0 ⇒ f(x) is decreasing on this interval.
Hence, The given function f(x) is decreasing on the interval : (-8, +∞).

George drew a line on a coordinate system by starting at (0,-5), then moved 2 units to the right and 1 unit up to locate each new point. Which is the equation of the line George Drew?
Answer:
y = 1/2x - 5
Step-by-step explanation:
I'm going to use slope-intercept form. Your y-intercept is already shown when x is zero, which is (0,-5). Your slope is defined as rise over run, so 1/2 in this case. This gives you an equation of f(x) = 1/2x-5

Identify the variable as the number of minutes, x. Identify the inequality symbol as greater than. Identify the constant as negative 56 minutes. Write the inequality as x minus 56.
Identify the variable as the number of minutes, x. Identify the inequality symbol as greater than. Identify the constant as Negative 56 minutes. Write the inequality as x greater-than negative 56.
Identify the variable as the number of minutes, x. Identify the inequality symbol as greater than. Identify the constant as 56 minutes. Write the inequality as x = 56.
Answer:
A.
Step-by-step explanation:
Given that Ebony waited for more than 56 minutes, option A summarizes the steps to write the inequality.
First, the term "more than" means greater than which is represented by the inequality symbol, >.
So, let's assume that the inequality variable is x and given that the minute she waited for is more than 56.
Writing this together will give
x > 56.
Hence, from the list of given options, only option A gives the actual representation of the statement; while others are not

(40, 96)
(85, 105)
(80, 104)
(96, 72)
Answer:
the answer is (40,96)
Step-by-step explanation:
Point P on the directed line segment from K to J has x and y coordinates that are three-fifths of the length of the line segment from K to J
(85, 105).
What are coordinates?The coordinates point to any point can be found by using the following formula.
X = [m/(m + n)](x₂ - x₁) + x₁
Y = [m/(m + n)](y₂ - y₁) + y₁
Given, On a coordinate plane, a line is drawn from point K to point J. Point K is at (160, 120) and point J is at (negative 40, 80).
The x- and y- coordinates of point P on the directed line segment from K to J such that P is Three-fifths the length of the line segment from K to J is;
X = [m/(m + n)](x₂ - x₁) + x₁
X = [3/(3 + 5)](- 40 - 160) + 160.
X = - 75 + 160.
X = 85.
Y = [m/(m + n)](y₂ - y₁) + y₁
Y = [3/(3 + 5)](80 - 120) + 120.
Y = - 15 + 120.
Y = 105
As a result, point P's x and y coordinates are such that P is three-fifths the length of the directed line segment from K to J (85, 105).

Healthy grains is planning a new design for its best-selling oatmeal. It has four containers to choose from
The question is incomplete:
Healthy Grains is planning a new design for its best-selling oatmeal. It has four containers to choose from. It costs the company $0.03 per cubic inch of oatmeal to fill a container. The company does not want the new container to cost more than $4.00 to fill. Which container should the company use? Use 3.14 for Pi.
Container A: A cylinder with height 7 inches and diameter 5 inches.
Container B: A cylinder with height 10 inches and B = 12.57 inches squared.
Container C: A cylinder with height 5.5 inches and radius 4 inches.
Container D: A cylinder with height 6 inches and radius 3 inches.
Answer:
Container B
Step-by-step explanation:
To find the answer you have to calculate the volume of each container and then, multiply that for $0.03 that is the cost per cubic inch to fill a container.
The formula to calculate the volume of a cylinder is:
V=πr^2h, where
r= radius
h= height
πr^2= base area
Container A:
The radius is half the diameter, so 5/2=2.5.
V= 3.14*(2.5^2)*7= 137.37
Cost= 137.37*0.03= 4.12
Container B:
12.57 inches is the base area, so:
V= 12.57*10= 125.7
Cost= 125.7*0.03= 3.77
Container C:
V= 3.14*(4^2)*5.5= 276.32
Cost= 276.32*0.03= 8.28
Container D:
V= 3.14*(3^2)*6
V= 169.56*0.03= 5.08
According to this, the answer is that the container that the company should use is container B because it costs less than $4.00 to fill.

There were 15 students running in a race. How many different arrangements of first, second, and third place are possible?
Answer:
The area 2730 possible arrangements of first, second, and third place.
Step-by-step explanation:
The order in which the students finish is important. For example A, B and C is a different finishing order(outcome) than B, A and C. So we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
3 from a set of 15. So
[tex]P_{(15,3)} = \frac{15!}{(15-3)!} = 2730[/tex]
The area 2730 possible arrangements of first, second, and third place.

In the interval 0 degrees < x < 360 degrees, find the values of x for which cos x =-0.4226
Give your answers to the nearest degree.
Answer:
The value of x within the interval are 115° and 245°Step-by-step explanation:
Given the trigonometric equation;
cos x =-0.4226
To get the value of x within the range 0° < x < 360°, we need to take the arc cosine of the value as shown;
x = arccos -0.4226
x = 114.99°
x ≈ 115°
Since x is positive in the 4th quadrant, the value of x can also be 360 - [tex]\theta[/tex]
where [tex]\theta = 115^{o}[/tex]
x2 = 360°-115°
x2 = 245°
The value of x within the interval are 115° and 245°
Answer:
The value of x within the interval are 115° and 245°

are parallel to each other.
bisect each other.
have the same slope.
are perpendicular to each other.
Answer:
bisect each other.
Step-by-step explanation:
The midpoints are the same point, so the diagonals bisect each other.
