Answer:

x = 10 (10.2 or 10.25)

Step-by-step explanation:

To find the length of the missing side, use the pythagorean theorem. Substitute x and 8 for a and b and 13 for c.

a^2 + b^2 = c^2

(x)^2 + (8)^2 = (13)^2

Evaluate the exponents.

x^2 + 64 = 169

Subtract 64 from both sides.

x^2 = 105

Square root both sides.

x = 10.2469

Round this to the nearest whole number (I'm assuming).

x = 10 (10.2 if rounded to nearest tenth; 10.25 if rounded to the nearest hundredth)

Answer:

1/2p+2

Step-by-step explanation:

1/2 distributed to p would be 1/2p. 1/2 distributed to 4 would be the same as 1/2 * 4/1. When you multiply straight across you get 4 in the numerator and 2 in the denominator (4/2). Next you just reduce the fraction, 4 divided by 2 is 2. So, the answer would be 1/2p+2. That answer would go into the 2 empty boxes. Hope thaat helps!!!

Evaluate A 2-B 2 for A = 3 and B = -4
r-ruslan [8.4K]
Hello there, and thank you for posting your question here on brainly.

Since we know what both of the exponents are, we can rewrite the equation for it.

3 * 2 - (-4)

We can evaluate from here.

I can see we have a positive number subtracting a negative number.

Use the rule where x - (-y) = x + y

2 * 3 + 4

Now we can get solving.

2 * 3 ==> 6

6 + 4 ==> 10

10 is the final answer.

Hope this helps! ☺♥

Sally and dana take a walk in the park for every 5 strides that sally make dana makes 4 strides after sally makes 120 strides ho
olga_2 [115]

Dana made 96 strides.

Step-by-step explanation:

Given,

Ratio of Sally's stride to Dana's strides = 5:4

Strides made by Sally = 120

Let,

x be the strides made by Dana.

Ratio of Sally to Dana = 120:x

Using proportion;

Ratio of Sally's stride to Dana's stride :: Ratio of Sally to Dana

5:4::120:x

Product of mean = Product of extreme

4*120=5*x\\480=5x\\5x=480

Dividing both sides by 5

\frac{5x}{5}=\frac{480}{5}\\x=96

Dana made 96 strides.

Keywords: ratio, proportion
