The perimeter of a triangular playground is 120 feet. The ratio of the measures of the sides is 3:5:7. Find the measure of the s

Hunter-Best [27]

24 feet, 40 feet, and 56 feet this is because using the ratio given 3:5:7

you can multiply
3x8=24
5x8=40
7x8=56
This shows that it follows the ratio lastly you need to make sure the numbers add up to 120
24+40+56=120
So A is your answer can I be marked brainiest please

Can someone help me with this problem?

Deffense [45]

The answer is -1.

First, distribute the negative inside the parenthesis of 1/2.
Next, turn all the denominators into 6 by multiplying by 3 or 2.

-1/2 + 2/3 + -1 1/6
Changes to -3/6 + 4/6 - 1 1/6

-3/6 + 4/6 = 1/6

1/6 - 1 1/6 = -1

I dont understand this can someone please help me.

Answer:

Difference = 2.25°

Step-by-step explanation:

Here we are given that at depth the Temperature T is inversely proportional to the depth x.

$T$ ∝ $\frac{1}{x}$

$T= 4500 \times \frac{1}{x}$

Where 4500 is constant

Now we have to find the difference in the temperature at 1200 mts and 3750 mts

1. x=1200

$T= 4500 \times \frac{1}{x}$

$T= 4500 \times \frac{1}{1200}$

$T= 3.75$

2. x=3750

$T= 4500 \times \frac{1}{x}$

$T= 4500 \times \frac{1}{3750}$

$T=1.2$

Hence Difference is

T = 3.75 -1.20

= 2.25

Therefore The difference of the temperature at 1200 mts and 3750 mts is T=2.25°

13. What are the x-intercepts of y = 2x2 + 6x - 20?

Brilliant_brown [7]

Answer:

x = -5, 2

Step-by-step explanation:

The first step to factor the equation is removing any factors/like terms that all of the variables share.

In the equation $y = 2x^2+6x-20$ , all numbers are multiples of 2, therefore you can factor out 2 from to equation

$y = 2(\frac{2x^2}{2} + \frac{6x}{2} -\frac{20}{2})$

$y = 2(x^2+3x-10)$

Next, you can factor the equation in the parenthesis. Since x^2 is not multiplied by anything, you know that the factors of x^2 must be x and x. Therefore, the two factors of -10 must add up to 3. The only two factors of -10/x that add up to 3 are 5 * -2.

The factors of the equation are then (2)(x+5)(x-2)

Lastly, set up only the factors containing a x to 0 in order to solve for x-intercept.

x+5 = 0; x= 0-5 ; x = -5

x - 2 = 0; x = 0 + 2; x = 2
