Step-by-step explanation:

You must follow the correct order of operations.

13 - 2(1 - 15)/4 =

Do the subtraction inside the parentheses first.

= 13 - 2(-14)/4

Find the solution set of the inequality
8x−8≤−72.

Answers

Answer:

x≤-8

Step-by-step explanation:

When solving 8x-8≤-72, first add 8 to both sides of the inequality.

This leaves you with 8x≤-64.

Divide both sides by 8: 8x/8 and -64/8

This leaves you with x≤-8 as your solution.

Evaluate.0.2 power of 4 =

Answers

Answer:

0.0016

Step-by-step explanation:

The expression 0.2 by the power of 4 when evaluated has a value of 0.0016

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

0.2 by the power of 4

Express as an equation

So, we have

0.2 by the power of 4 = 0.2⁴

When expanded, we have

0.2 by the power of 4 = 0.2 * 0.2 * 0.2 * 0.2

Evaluate the products

This gives

0.2 by the power of 4 = 0.0016

Hence, the solution is 0.0016

Find the degree measure of the angle expressed by 11x-6.

Answers

Answer:

Won't it just be 60, because it's an equilateral triangle.

Step-by-step explanation:

60 + 60 = 120

180 - 120 = 60

11x - 6 = 60

11x = 66

x = 66/11

x = 6

Let's substitute.

11(6) - 6 = 66 - 6 = 60

If two ratios are similar we called the ratios to be in proportion.

The length of side x is 6 cm.

What is proportion?

If two ratios are similar we called the ratios to be in proportion

We have,

Two shapes:

Consider the bigger shape width = 15 cm and length = 10 cm.

Consider the smaller shape width = 9 cm and length = x cm.

Let the ratio of bigger shape:

= Width / length

= 15/10

Let the ratio of smaller shape:

= Width / length

= 9/x

If the two figures are mathematically similar we can say that the two figures are in proportion.

We can write it as:

15/10 = 9/x

3/2 = 9/x

x = 6

Thus the length of side x is 6 cm.

A string reaches from the top of a 17-foot pole to a point 13 feet from the base of the pole. To the nearest tenth of a foot, how long is the string?

Answers

Answer:

21.4 feets

Step-by-step explanation:

Using Pythagoras rule :

The length of the string:

Hypotenus = sqrt(opposite² + adjacent²)

Length of string = sqrt(17² + 13²)

Length = sqrt(289 + 169)

Length of string = sqrt(458)

Length of string = 21.400

Length = 21.4 feets
