Answer:

1/2x

Step-by-step explanation:

For instance, if y shifts straightforwardly as x, and y = 6 when x = 2, the steady of variety is k = 3. Therefore, the condition depicting this immediate variety is y = 3x. ... As recently expressed, k is steady for each point; i.e., the proportion between the y-arrange of a point and the x-organize of a point is consistent.

Answer:

y = 1/2x represents a direct variation because it represents the direct variation formula: y = kx. In this case, the "k" is 1/2.

How much should you invest at 5% simple interest in order to earn $100 interest in 12 months?​
marissa [1.9K]

Answer:

You should invest $2000 at 5% simple interest in order to earn $100 interest in 12 months.

Step-by-step explanation:

Using the formula

I = Prt

where

I = Interest earned

P = The principal (let say in $)

r = The Interest Rate

t = time

Given that

  • I = $100
  • r = 5%
  • t = 12 month = 1 year
  • P = The principal amount needed to invest (let say in $)

Thus,

I = Prt

100 = P × 5% × 1

100 = P × 5/100 × 1

100 × 100 = P × 5

10000 = P × 5

P = 10000/5

  = 2000 (let say in $)

Thus, you should invest $2000 at 5% simple interest in order to earn $100 interest in 12 months.

Write a real world problem that you would represent with the equation 4x+5=37.
AURORKA [14]
Bob was 5 feet off the ground. He travels 4 feet every single second. How long will it take for him to reach 37 feet?

4x + 5 = 37

4x + 5 (-5) = 37 (-5)

4x = 32

4x/4 = 32/4

x = 8

It will take Bob ~8 seconds to reach 37 feet*

Find the value of x to the nearest tenth.
Lana71 [14]

Answer:

x = 14.7

Step-by-step explanation:

Use Law of Sines.

7/sin20=x/sin46

cross multiply

7sin46=xsin20

divide both sides by sin20 to isolate x

x = 7sin46/sin20

x = 14.72
