Help please find the volume of the sphere
Answer: 44.6cm³
The formula is [tex]\frac{4}{3} \pi r^3[/tex].
Since the formula had π (pi) pi is 3.14.
The radius is the line inside the sphere.
That being said, the radius is 2.2, so the line is 2.2 long.
Now, let's solve.
4/3 × 3.14 = 4.186 → 4.19
4.19 × 2.2³ = 44.6
Hence, 44.6 is the answer.
Why is a parallelogram a type of trapezoid?
Answer:
A trapezoid has only one pair of parallel sides, and a parallelogram has two pairs of parallel sides. So a parallelogram is also considered a trapezoid.

A state university has an annual tuition of $12,000. Bradley would like to attend this university and will save money each month for the next 4 years. His grandparents will give him $2,800 for his first year of tuition. Which plan shows the minimum amount of money Bradley must save to have enough money to pay for his first year of tuition?
Answer:
$767 per month for the next 4 years
Step-by-step explanation
first it’s minus the 2800 they gave him and that’s 9,200 then divided by the amount of months in a year which is 12 you end up with 766.6 but rounded that would be the closest answer and then when you multiply 767x12 it’s 9200 plus the 2800 it’s 12,000 which means it checks out.
Sally's cell phone bill os expected to increase by 7.5% next year . If b represnts the current bill, which expression represent the expected cost of the cell phone bill next year?
Answer:
The expression represent the expected cost of the cell phone bill next year is: c=1.075b.
Step-by-step explanation:
With the information provided, you can say that the expected cost of the cellphone bill next year would be equal to the current bill multiplied for 1 plus the increase in decimal numbers, so the increased amount is added to the current cost. The equation would be:
c=b*(1+0.075)
c=b*1.075
c=1.075b
According to this, the answer is that the expression represent the expected cost of the cell phone bill next year is: c=1.075b.

Find the sine of angle I
796
195
Answer:
sin I = 0.244
Step-by-step explanation:
Given that,
Perpendicular, P = 195
Hypotenuse, H = 796
We need to find the value of [tex]\sin(I)[/tex]. We know that,
[tex]\sin\theta=\dfrac{P}{H}[/tex]
Substitute all the values,
[tex]\sin I=\dfrac{195}{796}\\\\\sin(I)=0.244[/tex]
So, the value of sin(I) is equal to 0.244.

Each of the options below describes a relationship that you need to graph on a coordinate plane. Which of the options will have a slope of 8? Select all that apply. A) Doing 4 pages of homework in 20 minutes B) Cycling 32 miles in 4 hours C) Buying 10 shirts for $80 D) Reading 72 pages in 9 hours
Answer:
B ; C; D
Step-by-step explanation:
The slope measures the rate of change in the dependent variable per unit change in the independent variable :
From the options :
Doing 4 pages of homework in 20 minutes :
The number of pages done per minute = slope
Slope = 20 / 4 = 5
To cycle 32 miles in 4 hours:.
Number of miles to cycle per hour to achieve the feat :
Slope = 32 /4 = 8
Buying 10 shirts for $80:
Cost per shirt = slope
Slope = $80 / 10
Slope = 8
Reading 72 pages in 9 hours
Number of pages read per hour :
72 / 9 = 8 pages
The prices of different brands of eggs are given below.
Brand Price
A $1.99
B $1.79
C $1.89
D $3.59
E $1.89
F $1.89
Mrs. Silvio decided that she is most likely to spend $2.17 on eggs because this is the mean. Is Mrs. Silvio's reasoning correct?
A. No, Mrs. Silvio should have used $3.59 because it is the highest value given.
B. No, Mrs. Silvio should have used $1.80 because it is the range of the prices and is not affect by Brand D.
C. No, Mrs. Silvio should have used $1.89 because it is the mode and is not affected
by Brand D.
D. Yes, Mrs. Silvio is correct.
Answer:
C. No, Mrs. Silvio should have used $1.89 because it is the mode and is not affected by Brand D.
Step-by-step explanation:
The mode in a set of numbers is the most common, so If you bought eggs, the most common would be $1.89

Write an expression for the perimeter of the square. SIMPLIFY your answer
Answer:
P=16x-20
Step-by-step explanation:
The perimeter of a square can be found by adding up all the sides, and since it is a square we know that all the sides are the same. So we get P=4(4x-5), then we distribute the 4, and are left with the equation P=16x-20.

Answer:

Write an equation of the line with a slope of 23and y-intercept of −8.
If we have a y intercept of -8, that means that the point falls on the y-axis, therefore x = 0. So, we have a point (0, -8) and we have a slope m = 23.
y = mx + b
y = 23x + b
Now, we can plug in the point values x = 0, y = -8
-8 = 0 + b
b = -8
If we plug b back into our original formula, we get:
y = 23x - 8
In the parallelogram ABCD, M angle A =2x +50 and m angle C= 3x + 40. The measure of ZA is
Answer:
∠A = 70°
Step-by-step explanation:
I'm... guessing this is what you mean? It would've been helpful if you'd provided pictures.
Since all parallelograms consist of two pairs of vertically opposite angles, ∠A and ∠C are equivalent.
Which means that 2x + 50 = 3x + 40.
In which you solve the equation.
2x + 50 = 3x + 40
-2x -2x
50 = x + 40
-40 -40
x = 10
Now, to find ∠A, substitute x into the equation:
∠A = 2x + 50
x = 10
∠A = 20 + 50
∠A = 70
Hence, ∠A = 70°
Select the correct answer.

The scatter plot shows the relationship between summer and winter temperatures. What is the range of the cluster shown in the
scatter plot?
A)
51°F to 71°F average January high temperature
B)
58°F to 61°F average January high temperature
C)
91°F to 98°F average July high temperature
D)
94°F to 95°F average July high temperature
Answer:
D
Step-by-step explanation:
Since it's talking abtou clusters, the only "cluster" like part there is there is where 94 and 95 are, so it has to be D.
Using the scatter plot and the range concept, it is found that the correct option is:
C) 91°F to 98°F average July high temperature
The range of a data-set is the set that contains all possible output values.
In this problem, the average July temperature is the output, plotted as function of the average January temperature, which is the input.
It varies from 91ºF to 98ºF, hence, the correct option is:C) 91°F to 98°F average July high temperature

A ball is thrown in the air. The path of the ball is represented by the equation h=-t^2+8t, where t represents time in seconds and h represents the height of the ball in meters.
What is the maximum height of the ball?
How long is the ball in the air for before it hits the ground?
Answer:
a) 16 meters ; b) 8 seconds
Step-by-step explanation:
The function can be represent with a parabola whose vertex is its maximum point
for answer the first question we have to find the y of the vertex
first of all we have to find the x
Vertex (x) = -b/2a = -8/-2 = 4
if we substitute t with 4, we can find the y
Vertex (y) = -(4^2) + (8*4) =
= -16 + 32 = 16
so the answer is 16 meters
for answer the second question we have to find where the parabola intercepts the x axis, that means solve the associated equation:
-t^2 + 8t = 0
t^2-8t = 0
t(t-8) = 0
t = 0
t = 8
the parabola intercept the x axis in (0,0) and in (8,0)
if we find the distance between this two points we can answer to the question
8-0 = 8 seconds
