the sides of a vegetable garden in the shape of a right triangle are in the ratio of 3:4:5. if the perimeter is 96 feet, what is

pishuonlain [190]

Answer:

The shortest side has length 24 ft

Step-by-step explanation:

Try this: 3x + 4x + 5x =96 ft, or

12x = 96 ft

Then x = (96 ft) / 12, or x = 8

Multiplying this factor 8 by 3, we get 24. The shortest side has length 24 ft.

The middle-length side is 4(8), or 32.

The longest side is 5(8), or 40.

Check: Do 40 and 32 and 24 add up to 96 ft?

do 72 and 24 add up to 96 ft?

Yes.

$470 is raised by 30%. What is the value after the increase?

alekssr [168]

<h3>Answer: $611</h3>

Work Shown:

30% of 470 = 0.30*470 = 141

The value goes up by $141, so the answer would be 470+141 = $611

A slight shortcut would be to say

1.30*470 = 611

This works because 1.30 = 1 + 0.30 = 100% + 30%

Find the zero of the following function.<br>f(x)=x³-7x²+4x+12 <br><br><br><br><br><br><br><br>

chubhunter [2.5K]

Answer:

Step-by-step explanation:

Hello, we can notice that f(-1)=0 so (x+1) is a factor and we can write.

$f(x)=(x+1)(x^2-8x +12)\\\\=(x+1)(x-6)(x-2)$

The sum of the zeros is 8=6+2 and the product is 12=6*2

So the zeroes are 2, 6, -1

thanks
