Given:

Ratio of width to the length of television screen= $3:4$

Finding the width of the screen on having length of 32 inches

According to the given ratio and statement:

$\frac{3}{4}= \frac{width}{Length}$

$\frac{3}{4} =\frac{width}{32} \\\\width= \frac{3*32}{4}\\\\ width= \frac{96}{4}\\\\ width=24$

On having length=32, the width of the screen is 24.

Answer: x-intercept :12 & y-intercept ;-8

Step-by-step explanation:To find the x-intercept ,substitute in 0 for y and solve for x .

8x-12y=96

8x-12(0)=96

8x=96 (divide both # by 8)

x=12

To find the y-intercept ,substitute in 0 for x and solve for y .

8(0)-12y=96

-12y=96(Divide by -12 both )

y=-8

An actor invested some money at 5% simple interest, and $41,000 more than 4 times the amount at 9%. The total annual interest ea

NARA [144]

Answer:

The amount invested at 5%=$77,000
The amount invested at 9%=$349,000

Step-by-step explanation:

Let the amount invested at 5% simple interest =$x

He invested $41,000 more than 4 times the amount at 9%.

This amount is: $(4x+41000)

Total Annual Interest Earned = $35,260

Therefore, Time=1 year

Simple Interest $=\frac{Principal X Rate X Time}{100}$

Therefore, his total interest

=Interest from Investment 1 + Interest from Investment 2

$35260=\left(\frac{x*5*1}{100} \right)+\left(\frac{4x+41000*9*1}{100} \right)\\35260=0.05x+(0.36x+3690)\\35260-3690=0.05x+0.36x\\31570=0.41x\\\text{Divide both sides by 0.41}\\x=\$77000$

Therefore:

The amount invested at 5%=$77,000

The amount invested at 9%=$(4*77,000+41000)=$349,000
