Answer:

y = 2x + 4

y = 2x + 46x – 3y = -12

y = 2x + 46x – 3y = -12And

y = 2x + 46x – 3y = -12Andy = 2x

y = 2x + 46x – 3y = -12Andy = 2x-8x – 2y = 24

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.

Right trapezoid WXYZ is shown. Right trapezoid W X Y Z is shown. Sides X Y and W Z are parallel. Angle W is 73 degrees and angle
Sladkaya [172]

Answer:

∠WXY = 107°

Step-by-step explanation:

In a trapezoid, adjacent angles are supplementary, meaning they add up to 180°. ∠W and ∠WXY are adjacent, so they are supplementary. 180° - 73° = 107°.

Another way to do this is to know that there are 360° in a trapezoid. This is a right trapezoid, so two of the angles are 90°. One angle is 73°. 90° + 90° + 73° = 253°. 360° - 253° = 107°.

I hope this helps :))

Sinx=cos19∘<br> What is the value of x?<br><br> Enter your answer in the box.
rusak2 [61]
Remember that cos is just a translation of sin and vice versa.
So:
Sin(x) = Cos(90 - x)
Cos(x) = Sin(90 - x)

Therefore, to answer your question:
Cos(19) = Sin(90 - 19)
= Sin(71)
