Hi! :)

The answer is A, here's why:

When tipping at a restaurant, first you need to figure out how much you're tipping. You need to move the decimal left 2 places on how much you tip. So for 20%, you get .20

Then to figure out how much to tip for 20%, you would multiply that .20 by how much the bill was and that's your tip. So .20*30=6. Your tip should be 6 dollars, and the formula for that is t=.20b

A would be the answer to this problem. To find any tip, you usually calculate it by percentage . So to find the percentage of the bill, you multiply it by the percentage which is divided by 100. So A, t=0.20b would be the answer.

noname [10]

The inside angles of the triangle add to equal 180 and so does m/FEG with unknown triangle angle.

x+2x = x+40
2x = 40
x = 20

mFEG
= 20 + 40
= 60

A travel company is selling two different suitcases, each in the shape of a rectangular prism. Which statement is true?

9966 [12]

Answer:

Suitcase 2 is the better deal because it is less expensive than Suitcase 1 by approximately $0.01 per cubic inch ⇒ C

Step-by-step explanation:

Let us find the volume of each suitcase and find the price per cubic inch to chose the better deal

The formula of the volume of a rectangular prism is V = L × W × H, where

L is the length of it
W is the width of it
H is the height of it

Suitcase 1:

∵ Its length is 14 inches

∵ Its width is 9 inches

∵ Its height is 22 inches

- Substitute them in the formula of the volume above

∵ V = 14 × 9 × 22

∴ V = 2772 inches³

∵ The cost of it is $139.99

- Divide the cost by the volume to find the cost per cubic inch

∵ The cost per cubic inch = 139.99 ÷ 2772

∴ The cost per cubic inch ≅ 0.05

∴ The cost per cubic inch is approximately $0.05

Suitcase 2:

∵ Its length is 18 inches

∵ Its width is 10 inches

∵ Its height is 22 inches

- Substitute them in the formula of the volume above

∵ V = 18 × 10 × 22

∴ V = 3960 inches³

∵ The cost of it is $158.99

- Divide the cost by the volume to find the cost per cubic inch

∵ The cost per cubic inch = 158.99 ÷ 3960

∴ The cost per cubic inch ≅ 0.04

∴ The cost per cubic inch is approximately $0.04

∵ 0.04 is less than 0.05

∵ 0.05 - 0.04 = 0.01

∴ Suitcase 2 is less expensive than suitcase 1 by $0.01

∴ Suitcase 2 is the better deal

Suitcase 2 is the better deal because it is less expensive than Suitcase 1 by approximately $0.01 per cubic inch

Euler's method:

Leokris [45]

Answer:

f(1) ≈ 2.7864

Step-by-step explanation:

You appear to want a couple of iterations of ...

... y[n+1] = y[n] +arcsin(x[n]·y[n]}·(x[n+1] -x[n])

... x[n+1] = x[n] +0.5

... x[0] = 0

... y[0] = 2

Filling in the values, we get

... y[1] = 2 + arcsin(0·2)·0.5 = 2

... y[2] = 2 + arcsin(0.5·2)·0.5 = 2 +(π/2)·0.5 ≈ 2.7864 . . . . corresponds to x=1
