Answer:
6
Step-by-step explanation:
if you divide 18 by 4 you get 4.5, and if you divide 27 by 4.5 then you get six. hope this is right :/
Answer: 6 books
Work: Okay, The first thing I did was find out how much one book costs. To find that out, I divided $18/4, and the answer is $4.50 per book. Now, we add $4.50 until it's $27. I did that, and it was just 2 more books. (4.50 + 4.50 is $9, so add nine dollars to $18, and that would be $27. Then, divide 27/4.5, and you get 6, meaning the 6 books)
Sorry if this was confusing, but I hope I helped you. :)
Jeremey performs the same operations on four values of x. He records each resulting y-value in a table, as shown below. Which equation shows the operations Jermey performs on x to get to y
Answer:
Y=4x-3
Explanation: If we look 2 = 5 We can do 4(2)= 8 -3 = 5 So that the answer and 4(4)= 16-3 = 13 so these are the Y so this is the answer!

Suppose a cylinder has a diameter of 18 feet and a height of h feet. Which equation can be used to find V, the volume of the cylinder in cubic feet?
Answer:
Volume of a cylinder, V = πr^2h
but r= d/2
therefore, Vol = π(d/2)^2h
from the parameters given,
Vol = π(18/2)^2h
=81πh

simplify the expression a² • 3a and explain your steps pls
Answer:
3a^3
Step-by-step explanation:
Ok I got you bud now the the first thing to notice that they're all the same variable. so the way I learned to look at is like this
1a^2 x 3a^1
so the reason I put it like this is so I remember that in front of every variable is a coefficient. so you would first multiply the coefficient
3x1=3
3
then multiply the a's you have one a that is being squared and one a to the first power so since your multiplying them you just add the exponents
a^1 + a^2 = a^3
so when you put it all together it says 3a^3
hope this helps

A squirrel burrowed 6 holes in 2 minutes. How many holes could the squirrel burrow in 7 minutes
Answer:
He burrows 6 holes in 2 minutes which means that he can burrow 3 holes in 1 minute.
To determine how many he can burrow in 7 minutes, you would multiply the
unit rate of 3 holes in 1 minute by 7.
He would burrow 21 holes in 7 minutes.
Step-by-step explanation:

What are the slope and the y-intercept of the line of best fit on this scatter plot?

The y-intercept is , and the slope is .
B.
The y-intercept is , and the slope is .
C.
The y-intercept is , and the slope is .
D.
The y-intercept is , and the slope is .
Answer:
the y-intercept is 8 and the slope is -4/3 .
Step-by-step explanation:
The y - intercept is (0, 8) and the slope is -4/3
What is the y-intercept?"It is the point at which the graph of the function intersects the y-axis"
What is slope?The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
For given example,
We can observe that the line of best fit on this scatter plot passes though points (0, 8) and (6, 0)
Using the slope formula,
⇒ slope = (0 - 8)/(6 - 0)
⇒ slope = (-8)/6
⇒ slope = -4/3
Also, we can observe that the line of best fit on this scatter plot intersects y-axis at point (0, 8)
So, the y - intercept is (0, 8)
Therefore, the y - intercept is (0, 8) and the slope is -4/3

A 35-foot tall pole is leading towards a building. To stop the pole from leaning further, a 48-foot long cable is secured from the top of the pole to a stake in the ground opposite of the building. If the stake is 30 feet from the pole, what angle does the cable make with the pole?
Round the answer to the nearest tenth.
9514 1404 393
Answer:
38.5°
Step-by-step explanation:
A triangle solver can give an answer easily. The angle is 38.5°.
__
The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.
C = arccos((a² +b² -c²)/(2ab))
Here, we have a=35, b=48, c=30, so the angle is ...
C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°
The angle the cable makes with the pole is about 38.5°.

Find the volume of a pyramid with a square base, where the side length of the base is
14.4 m and the height of the pyramid is 15.3 m. Round your answer to the nearest
tenth of a cubic meter.
Answer:
Volume of pyramid with square base is 1057.54 m³
Step-by-step explanation:
We are given:
Length of base of pyramid = 14.4 m
Height of pyramid = 15.3 m
We need to find:
Volume of pyramid with square base
The formula used is: [tex]Volume=\frac{1}{3}\times a^2 \times h[/tex]
Where a = base of pyramid and h is height
Putting values and finding volume
[tex]Volume=\frac{1}{3}\times a^2 \times h\\Volume=\frac{1}{3}\times (14.4)^2 \times (15.3)\\Volume=\frac{1}{3}\times 207.36 \times 15.3\\Volume=1057.54 \ m^3[/tex]
So, Volume of pyramid with square base is 1057.54 m³
Answer:
1057.5

identify the slope and write the equation of the line .
Answer:
y=-2x+5; slope is -2
Step-by-step explanation:
slope is rise/run. we can see it rises 2 and goes left one which would give us rise/run=2/-1=-2. that is our slope.
using y=mx+b to write the equation, m is slope and b is the y-int.. we can see that the y-int. is (0,5). we can plug 5 into b.
plugging b and m in we can get the equation: y=-2x+5

Answer: m∠T = 48°
ΔMAT has MA = MT
=> ΔMAT is a isosceles triangle at M
=> ∠A = ∠T = (180° - ∠M)/2
=> x + 20 = (180 - 3x)/2
⇔ 2x + 40 = 180 - 3x
⇔ 5x = 140
⇔ x = 140/5
⇔ x = 28
=> ∠A = ∠T = 28 + 20 = 48°

Find the surface area of the 3D solid. Round to one decimal place.
Answer:
172.5
Step-by-step explanation:
The formula for the surface area of a right circular cone (the following shape) is πr( r + √h^2 + r^2). Since the radius (r) is already given (3) and the height (h) is already given (15), you just replace each r with 3 and h with 15. After solving this out, you should get 172.45, which rounds to 172.5 to the first decimal place

(11x + 8) + (8x + 12) =27
Answer:
11x + 8 +8x +12 =27 (drop the parenthesis, there's no actual need for them)
19x +20 =27 (i combined like terms and then subtracted 20 from both sides)
19x = 7 (divide both sides by 19 to get x alone)
x= 7/19 or 0.36842105 (the answer)

Hana has some blue paint. She wants to lighten the shade, so she mixes in 1
cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of
white paint at a time. After adding 4 cups, she decides the color is too light.
Answer:
The answer is below
Step-by-step explanation:
Hana has some blue paint. She wants to lighten the shade, so she mixes in 1 cup of white paint. The color is still too dark, so Hana keeps mixing in 1 cup of white paint at a time. After adding 4 cups, she decides the color is too light.
How would she express the amount of paint to add to be between too dark and too light.
Solution:
After adding a cup of white paint, the color is still dark, she adds the second cup of paint and the color is still dark. She adds the third cup of paint and the color is still dark but when she adds the fourth cup of white paint, the color became too light.
This means that the amount of paint to add to be between too dark and too light is between the third and fourth cup.
Let w represent the amount of paint to add to be between too dark and too light. Hence:
3 < w < 4
