y=8-2x
x+3y=12

Yes or No?

Answer:

im pretty sure that it is B please correct me if i am wrong:D

Answer:

B. 70°

Step-by-step explanation:

Answer:

13

Step-by-step explanation:

(5y+4-y)/6 + 2 = 7

(5y+4-y)/8=7

5y-y+4/8=7

4y+4/8=7

4y+4=56(Multiplied 8 and 7)

4y=56-4

4y=52

52 divided by 4 = 13

Hope this helped!

Answer:

12

Step-by-step explanation:

it will be 12 inches greater

The volume of the front door is 72 cubic inches greater than the volume of the bedroom door.

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

Assuming that the bedroom door has the same height as the front door, we can use the formula for the volume of a rectangular solid to calculate the volume of each door.

Let L, W, and H be the length, width, and height of the front door, and let L' and W' be the length and width of the bedroom door.

We know that Lx W = 72 (since the area of the base is 72 square inches), and L' x W' = 60 (since the area of the base is 60 square inches).

The volume of the front door is given by V = LWH.

The volume of the bedroom door is given by V' = L'*W'*H.

Since the height is the same for both doors, we can divide V by V' to get the ratio of the volumes:

V/V' = (LWH)/(L'*W'H)

V/V' = (LW)/(L'*W') (canceling out the heights)

Substituting in the given values, we get:

V/V' = (72)/(60)

V/V' = 6/5

This means that the volume of the front door is 6/5 times the volume of the bedroom door.

To find the difference in volume, we can subtract the volume of the bedroom door from the volume of the front door:

V - V' = (6/5)*V' - V'

V - V' = (1/5)V'

V - V' = (1/5)(L'*W'*H)

Substituting in the values for L', W', and H, we get:

V - V' = (1/5)*(L' x W' x H)

V - V' = (1/5)(√(60) x √(60) x H)

V - V' = (1/5) x 360

V - V' = 72

Therefore,

The volume of the front door is 72 cubic inches greater than the volume of the bedroom door.

Answer:

0.0011904

Step-by-step explanation:

Given that:

Number of slips = 7

Sample space = (1, 2, 3, 3, 5, 6, 7)

Numbwe of slips drawn = 4

Probability = required outcome / Total possible outcomes

Note ; selection is without replacement ;

P(drawing 1) = 1 /7

P(drawing 2) = 1 /6

P(drawing 3) = 1/5

P(drawing 4) = 1/4

1/7 * 1/6 * 1/5 * 1/4 = 0.0011904

Answer:

Bank A

Step-by-step explanation:

We find the Simple Interest for each Bank

Bank A

A savings account at bank A earns 5%

simple interest.

Where

P = $5,000.00

R = 5%

T = 2 years

Compound quarterly = 4

First, convert R percent to r a decimal

r = R/100

r = 5%/100

r = 0.05 per year,

Then, solve our equation for A

A = P(1 + r/n)^nt

A = 5,000.00(1 + 0.0125/4)(4)(2)

A = $ 5,522.43

A = P + I where

P (principal) = $ 5,000.00

I (interest) = $ 522.43

For Bank B

P = $5,000.00

R = 4%

T = 2 years

Compound quarterly = 4

First, convert R percent to r a decimal

r = R/100

r = 4%/100

r = 0.04 per year,

Then, solve our equation for A

A = P(1 + r/n)nt

A = 5,000.00(1 + 0.01/4)(4)(2)

A = $ 5,414.28

A = $ 5,414.28

A = P + I where

P (principal) = $ 5,000.00

I (interest) = $ 414.28

Therefore, the bank that would give Gabriel more interest is Bank A
