Could someone help me with this im so confused

Answers

Answer 1

Ok so basically the number by the X is your slope (m) and the other number is your y-intercept (b) so for example the first question your slope (m) 2/3 and your y-intercept (b) -2

The cylinder and the sphere below have the same radius and the same volume. What is the
height of the cylinder?

A.8m
B.6 m
C.4m
D.9m

Answers

The answer would be 8 or A

Step by Step Explanation:

First you have to find the volume of the Sphere.

Set the problem up like this: V = Volume
V= 4/3 • pi (3.14) • 6(3)
= 904.32

Now you have to volume and as stated the volume and radius is the same for both the cylinder and sphere. So now you plug in the answers for the letters.
Formula for (V) Volume of Cylinder is:
V= Pi (3.14) • R (radius) (2) • H (height)
So plug in for what you know
904.32 = 3.14 • 6(2) • H
904.32 = 3.14 • 36 • H
113.04/904.32 = 113.04 • H/113.04
8 = H

The answer is A

solve for m
–m + 8 = –4m − 10

Answers

Answer:

m=-6

Step-by-step explanation:

-m + 8 = -4m -10

+m. +m.

8= -3m -10

+10. +10

18 = -3m

/-3m /-3m

-6=m

Answer:

m=-6

Step-by-step explanation:

–m + 8 = –4m − 10

Subtract 8 from both sides

-m+8-8=-4m-10-8

Simplify:

-m=-4m-18

Add 4m to both sides

-m+4m=-4m-18+4m

Simplify:

3m=-18

Divide both sides by 3

3m/3=-18/3

-18/3=-6

m=-6

Complete the equation of the line whose y-intercept is (0,5) and slope is -9.

y=

Answers

Answer: y=-9x+5

Step-by-step explanation:

slope intercept form is y=mx+b

simply plug in the values.

m= the slope

the slope you gave was -9, so plug that in to m.

b= the y intercept aka when the number touches the y axis. in this case, it would be 5.

y=-9x+5

Elise had a credit card balance of -$120. She
made a payment of $70 this month. Write and
then evaluate a SUBTRACTION expression to
find her new credit card balance.

Answers

Answer:

15.50+n=325.00

Step-by-step explanation:

15.50+what she had in the bank already = what she has now

Step-by-step explanation:

Elise's new credit card balance is $-50.

Elise's credit card balance is negative. This means that she has withdrawn more money than she has deposited. Elsie thus owes the bank $-120. If she paid $70, the amount she owes would be reduced by $70.

Elise's new credit card balance = credit card balance + payment made

$-120 + $70 = $-50

Martha rented a sedan at a cost of $21.25 a day for three days. She drove 980 miles at 25 cents a mile. Gas cost $63.45 what was the cost per mile

Answers

Answer:

38 cents per mile

Step-by-step explanation:

Let us first calculate the total expenditure by Martha

= 21.25*3= $ 63.75

Cost of gas =$ 63.45

Therefore cost per mile = 127.2/980= 0.1297+0.25= $0.3797 or 38 cents per mile

Answers

Answer:

because 3 spheres is inside the cylinder and they are placed close together

=> The height of the cylinder is 3 times the diameter

=> the height is 18cm

the volume of the cylinder is 3,14.18.(6/2)² = 508,68

because 3 spheres have the same diameter

=> the volume of 3 spheres is 4.3,14.3³ = 339,12

=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56

Step-by-step explanation:

Answer:

The answer is 508,68

Step-by-step explanation:

Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height

Since the radius of the base is equal to 3 and since the area of its cylinder is equal to

[tex]314 \times 3 \times 3 = 28.26[/tex]

When the height equal to 18

Then the volume equal to

[tex]28.26 \times 18 = 508.68[/tex]
