Perimeter is adding all the outside dimensions. The left side of the shoae is a rectangle, so the bottom line is the same as the top line, 10 feet.

Perimeter = 8 + 10 + 8.9 + 10 + 4 = 40.9 ft.

Suppose you roll a standard number cube and spin a spinner with four equal-sized sections labeled 1, 2, 3, 4. What is the probab

Kitty [74]

Answer:

25% probability you will roll a prime number and spin a prime number

Step-by-step explanation:

If we have two events, A and B, and they are independent, we have that:

$P(A \cap B) = P(A) \times P(B)$

In this question:

Event A: Rolling a prime number.

Event B: Spinning a prime number.

Both the cube and the spinner have four values, ranging from one to four.

2 and 3 are prime values, that is, 2 of those values. Then

$P(A) = P(B) = \frac{2}{4} = \frac{1}{2}$

What is the probability you will roll a prime number and spin a prime number

The cube and the spinner are independent of each other. So

$P(A \cap B) = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4} = 0.25$

25% probability you will roll a prime number and spin a prime number

-2 = -5t + 10t + 2t<br><br> t = ? <br> Help!

romanna [79]

Hello there!

$-2 = -5t + 10t + 2t\\$

Explanation:

↓↓↓↓↓↓↓↓↓

First you had to switch sides.

$-5t+10t+2t=-2$

Then you add similar elements.

$7t=-2$

Divide by 7 from both sides of the equation.

$\frac{7t}{7}=\frac{-2}{7}$

Simplify it should be the correct answer.

$t=-\frac{2}{7}$

Answer⇒⇒⇒⇒⇒t=-2/7

Hope this helps!

Thank you for posting your question at here on Brainly.

Have a great day!
