Answer:

171 m

Step-by-step explanation:

Okay, so we have to find the area of all the shapes that make up the prism:

I'm going to start with the side rectangles:

5 x 7 = 35

There's 2 of them so:

35 x 2 = 70

Now let's go onto the side triangles:

4 x 6 = 24 (normally it would then be ÷ 2, but because there's 2 triangles, you don't have to do that)

Then we do the bottom rectangle:

6 x 7 = 42

So, adding them all together:

35 + 70 + 24 + 42 = 171

So the surface area of the prism is 171 m

hope this is right:)

A dice has 6 sides. What is the probability of rolling a 3? Explain how.

Answers

The probability is 1/6
because there are a total of 6 numbers you could get in one roll, that goes on the bottom of the fraction.
there is only one “3” on a die so you can only possibly roll a three 1/6 of the time.

The answer is 1/6 because there are 6 sides the denominator and only one 3 the numerator

NF- 26. Which choice is equal to 2.5? *

None of the decimal is equivalent to 2.5

What is Decimal?

In a decimal number, the digits are separated by a decimal point. The digits to the left of the decimal point represent the whole number part, while the digits to the right of the decimal point represent fractional parts or decimal fractions.

To determine which choice is equal to 2.5, let's evaluate each option:

A) 2/5: This fraction is less than 1. It is equivalent to 0.4, which is bequal to 2.5.

B) 2 1/5: This is a mixed number.

To convert it to a decimal, we add the whole number part (2) to the fraction part (1/5).

2 + 1/5 = 10/5 + 1/5 = 11/5

So, 2 1/5 is equal to 11/5, which is 2.2. It is not equal to 2.5.

C) 2 4/10: Similar to the previous choice, we convert this mixed number to a decimal.

2 + 4/10 = 20/10 + 4/10 = 24/10

So, 2 4/10 is equal to 24/10, which simplifies to 12/5 or 2.4. It is not equal to 2.5.

D) 5/4: This is a fraction.

To convert it to a decimal, divide the numerator (5) by the denominator (4).

5/4 = 1.25

So, 5/4 is equal to 1.25, which is not equal to 2.5.

None of the given choices is equal to 2.5.

Ciara brought $240 to spend on gifts for her family. she found 8 identical statues at the gift shop. she had $72 leftover. how much did each statue cost?(please write an equation for the answer like 2 step equation)

Answers

Answer:

$21 each

Step-by-step explanation:

Since she had $72 left that means that she spent $168 so then you divide that by the 8 identical statues.

$240 - $72 = $168

$168/8 = $21

Answer:

$21

Step-by-step explanation:

Price of each statue = x

Price of 8 statues = 8x

Price of 8 statues plus money left over = 8x + 72

Original amount of money = 240

Equation:

8x + 72 = 240

Subtract 72 from both sides.

8x = 168

Divide both sides by 8.

x = 21
