Solving inequalities, what is x/18>27

Mathematics
1 answer:
Lunna [17]3 years ago
7 0

Answer:   x > 486

Explanation:

We have some number x and we divide that by 18. The result is larger than 27. To find possible values for x, we need to undo what is happening to x. The opposite of division is multiplication. We multiply both sides by 18 to cancel out the "18" on the left side, which will isolate x to get it to its own side.

This is what the steps look like

x/18 > 27

18*( x/18 ) > 18*27 .... multiplying both sides by 18

x > 486 ... note the 18's cancel on the left side

So this means x is some number greater than 486.

Pythagorean Theorem Word
diamong [38]

Answer:

40 miles

Step-by-step explanation:

In the attached diagram, Point A is the starting point and C is the end point. We want to determine the distance from A to C.

The path driven forms a right triangle in which AC is the hypotenuse.

We therefore use the<u> Pythagorean Theorem</u> to solve for the AC.

Pythagorean Theorem: Hypotenuse^2=Opposite^2+Adjacent^2

|AC|^2=32^2+24^2\\|AC|^2=1600\\|AC|=\sqrt{1600}\\ |AC|=40$ miles

The  straight  line distance from the starting point is 40 miles.

A banner is made of a square and a semicircle. The square has side lengths of 22 inches. One side of the square is also the diam
anastassius [24]
Assuming the square and the semicircle aren't merged somehow, and we need to calculate their full area, we should take into account:

Area of a square:
(Side length)² = 22² = 484 square inches

Area of a circle with a diameter of 22inch:
3'14 · (radius)² = 3'14 · 11² = 379'94 square inches

Since we have half a circle, the total areas to add will be:
1/2 · 379'94 + 484 = 673'97

Which of the following are true statements about the expression 5^12?
Fed [463]

Answer:

A. 5 is the base

D. 12 is the exponent and tells us how many times we should multiply 5 by itself

Step-by-step explanation:

The given expression is

5^{12}

This is a number written in an index notation.

The base is 5.

The exponent is 12.

The exponent tells us how many times the base multiplies itself.

Therefore 5^{12} means, 5 multiplies itself 12 times.

Options A and D are correct.
