Step-by-step explanation:

The first question is pretty straight forward, all you have to do is get a ruler and measure how long XY is. Then draw another line that has the same exact length next to it and label it AB, by drawing A and B at the end points like how they did in the line XY

For the second question measure the length of FG and then measure the length of YZ and add the two lengths and then draw a line with that length and then label it CD by labeling the end points C and D.

For the last question measure the length of MN and then divide that length in 2 and then label that midpoint O. for example if I had the same problem and I put my ruler on the line and saw the length was 10 inches, I would go to where it's 5 inches and label the midpoint on the line. You also want to draw a perpendicular line through that midpoint O.

One x- value of the solution is : -2 or -8

An Equation is an algebraic statement that shows that two quantities are equal.

Analysis:

for one x-value of a solution, f(x) = g(x)

Answer:

18

Step-by-step explanation:

substitute x = 5 into g(x) and x = 2 into h(x)

g(5) + h(2)

= 2(5) - 5 + 4(2) + 5

= 10 - 5 + 8 + 5

The equation for a circle with a center (-2, 8) and a radius of 9 will be (x + 2)² + (y − 8)² = 81.

A circle can be characterized by its center's location and its radius's length.

Let the center of the considered circle be at the (h,k) coordinate.

Let the radius of the circle be 'r' units.

Then, the equation of that circle would be:

(x - h)² + (y - k)² = r²

Write an equation for a circle with a center (-2, 8) and a radius of 9.

Then the equation will be

(x + 2)² + (y − 8)² = 9²

(x + 2)² + (y − 8)² = 81

Answer:

$189

Step-by-step explanation:

35% of 140 = 49

140 + 149 = 189

Tom's total saving this year is $189.

It is a 35 percent increased saving from last year's $140.

Percentages are fractional values where the denominator is fixed to be 100.

To convert percentage into number, we multiply by 100.

In the question, we are informed that Tom was able to save 35% more this year than he did last year.

We are asked if he saved $140 last year, then how much did he save this year.

The increase in Tom's savings = 35% of last year's savings,

or, the increase = 35/100 * 140 (To convert percentage into quantity, we divide by 100).

or, the increase = $49.

Therefore, Tom's total savings this year = Last year's savings + Increase,

or, Tom's total saving this year = $140 + $49 = $189.

At  150 minutes the length of the first candle is 3 times that of the other.

The complete question is

There are two candles of same length and same size. Both of them burn at uniform rate. The first one burns in 5 hours and the second one burns in 2 hours. Both the candles are lit together. After how many minutes the length of the first candle is 3 times that of the other?

When two algebraic expression are equated using an equal sign an equation is formed.

First candle burns for 5 hours

Second candle burns for 2 hours

Let the length of candle be l.

After t time (in minutes), length of first candle =l−(lt/300)

Length of second candle =l− (lt/120)

From the data given

l -  (lt/120) = 3 * (l−(lt/300))

On simplifying

4t = 600

t = 150 minutes

Therefore after 150 minutes the length of the first candle is 3 times that of the other.

Answer: Probability = 90%

Step-by-step explanation:

In a drawer we have:

2 black shirts

7 white shirts

11 gray shirts

If we would randomly pick a shirt, what are the chances of it not being black?

To do that, we first need to calculate the probability of getting a black shirt.

To calculate that, we need to divide the number of black shirts by the total number of shirts.

Black shirts = 2

Total shirts = 2 + 7 + 11 = 20

That will be 2 black shirts divided by 20.

We get 0.1

If we multiply 0.1 by 100%, we get a 10% chance to get a black shirt.

Now, to know to chances of not getting a black shirt, we just need to subtract 10% from 100%.

And that will be 90% chances of not getting a black shirt.

Probability = 90%

The area of a 2D form is the amount of space within its perimeter. The surface area of the prism is 232 in².

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The surface area of the prism is,

Surface area = 2 [(2 × 8)+(8 × 10)+(2 × 10)]

                      = 232 in²

Hence, the surface area of the prism is 232 in².
