state of each triangle is acute, obtuse, or right

The length of DE is 6 inches.

I can see that from the image, DE is a horizontal line segment that is 6 units long. This is because the x-axis is labeled in units, and DE spans 6 units on the x-axis.

we know that

The triangle XYZ and DEF are similar triangles

therefore

The ratio of their corresponding sides is equal

12/8 = 9/x

x = 8 * 9/12

x = 6 Units.

Therefore the length of DE is 6 inches.

Answer:

- 10

Step-by-step explanation:

Wherever you see an x, put in a minus 1.

f(-1) = -3(-1)^2 + 2x - 5

f(-1) = -3(1) + 2(-1)  - 5

f(-1) = - 3 - 2 - 5

f(-1) = - 10

Answer:

y = 3x-3

Step-by-step explanation:

y = mx+b

m is your slope and b is your y-intercept

plug those numbers in

y = 3x-3

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

We have m = 3 and b = -3. Substitute:

Look at the picture.

ΔZYX and ΔDYC are similar. Therefore the lengths of sides are in proportion:

The probability of Felipe winning a specific prize in the charity raffle is 1/9 or approximately 0.111.

The subject of the question is Mathematics and the grade level is Middle School.

To determine the probability of Felipe winning a specific prize from the 9 prizes, we need to divide the number of desired outcomes (one specific prize) by the total number of possible outcomes (9 prizes in total). Therefore, the probability of Felipe winning a specific prize is 1/9, or approximately 0.111.

For example, if Felipe wants to calculate the probability of winning the first prize, he has 1 desired outcome (winning the first prize) out of 9 possible outcomes (9 prizes in total). Thus, the probability of winning the first prize is 1/9.

Answer:

27.27%

Step-by-step explanation:

Formula:

%= 100*(revenue-cost)/ revenue

%= 100* (121-88)/121

By 27.27%  the ticket price mark up.

The ratio of the increased value to the original value, multiplied by 100, is the percentage increase formula. It is outlined as a percentage. Anything's value will increase if it is valued more, so will its proportion.

Given:

Mark bought a concert ticket for $88.

Mark sold it for $121.

Change in amount= 121- 88 = $33.

So, the percent increase

= (121- 88) / 88 x 100

= 33/121 x 100

= 3/11 x 100

= 27.27%

Hence, the percent mark up is 27.27%.

Step-by-step explanation:

Remember your order of operations. Multiplication happens before subtraction.

3.912 - 9.15

-5.238

There are no answer choices, so I will just list a few. But first, we need to create the equation.

Plugging in (5,7) into the equation y=mx+b, we can solve for b since all of the other variables are known, with m=3 as the slope.

So, 7=3*5+b

7=15+b

b = -8

y=3x-8 is your equation.

So, you can plug in any value of x you get a certain value of y.

to find another point on the line add 3 to the y-coordinate and add 1 to the x-coordinate

(5, 7) → (5 + 1, 7 + 3) → (6, 10) ← other point on line

continue to do this for other points

(6, 10) → (6 + 1, 10 + 3) → (7, 13)

Answer:

C) m = -63 is your answer

Step-by-step explanation:

Isolate the variable (m). Note the equal sign, what you do to one side, you do to the other.

Multiply 3 to both sides

-21 = (m/3)

(-21)(3) = (m/3)(3)

m = (-21)(3)

Combine like terms. Simplify.

m = -21 * 3

m = -63

C) m = -63 is your answer

Answer: False

A plane is a flat line that extends forever in all directions. Think of a flat piece of paper that does not bend or curve. If you intersect two planes, then they will form a straight line. This line will extend forever both directions. There are infinitely many points on this line of intersection. You can think of a book as a good example: the pages are the planes while the spine is the line of intersection.

To solve the inequality 12x+7<−11 OR 5x−8>40, isolate x in each equation. The solutions are x < -1.5 and x > 9.6.

To solve for the inequality 12x+7<−11 OR 5x−8>40, we first need to simplify each equation separately i.e isolate x in each separate equation.

For the inequality 12x + 7 < -11: Subtract 7 from both sides, which gives 12x < -18. Then divide by 12 which will yield x < -1.5.

For the inequality 5x - 8 > 40: Add 8 to both sides, which gives 5x > 48. Then dividing both sides by 5, we get x > 9.6.

Our answer is therefore x < -1.5 OR x > 9.6. This means that any x value satisfying either of these conditions will satisfy the original inequality.

To solve the compound inequality 12x + 7 < -11 OR 5x - 8 > 40, solve each inequality separately to find x < -1.5 or x > 9.6. This means x can be any value less than -1.5 or greater than 9.6.

To solve for x in the given compound inequality, we need to handle each inequality separately.

Step-by-Step Solution:

Therefore, the solution to the compound inequality is x < -1.5 OR x > 9.6.

This means x can be any number less than -1.5 or greater than 9.6.

Step-by-step explanation:

First, plot all the points on a graph. Then draw Liza's path. Add them all up and multiply by 400.

28 · 400 = 11,200.

Liza walked 11,200 yards.

My graph is attached. The blue line is Liza's path and each coordinate point is labeled.

I hope this helps u!!

:)

Answer:

11,200 yards.

Step-by-step explanation:

Distance between two points is;

Distance = √(x²+y²)

Distance between Bank and post office = √(5²+0)

                                                                     = 5

Distance between post office and dry cleaner = √(0+9²)

                                                                              = 9

Distance between Dry cleaner and pizza shop = √(0+5²)

                                                                                = 5

Distance between Bank and pizza shop  = √(9²-0)

                                                                    = 9

Total distance = 5+9+5+9

                       = 28 units

1 unit ⇒ 400 yards

28 units ⇒ (28×400)

              ⇒ 11,200 Units

Answer:

315, 317, and 319

Step-by-step explanation:

So first we have to set the equation up. Since it is odd, we would write

[tex](x-2)+x+(x+2)=951[/tex]

where x is the middle integer. This gets you

[tex]3x=951[/tex]

Solving for x we get

[tex]x=317[/tex]

Since x was the middle, we subtract 2 and add 2 and put them together in ascending order, or 315, 317, and 319.

4 over 4 (4/4) is equal to 1.

The equation can be rewritten as X = 4/32

4/32 can be simplified to 1/8

So you have X = 1/8

Answer:

1/8

Step-by-step explanation:

to simplify 4/32, you just have to see how many times 4 goes into 32, in this case the answer is 8. A good rule of thumb is if the smaller number is on the top of the fraction, you will get a fraction for an answer, so the 4 turns into 1 and the 32 turns into 8.

Answer:

divided by 8

7.10

The cost c of one baseball if, baseball bat and 8 baseballs cost $163.25, and the bat cost $106.45 is $11.36.

It is a mathematical statement that says, "this is equivalent to that," in other words. There appears to be an equal sign in the middle, a mathematical expression on the right, and a mathematical expression on the left.

Given:

The total cost of a baseball bat and 8 baseballs cost is $163.25,

The cost of one bat is $106.45,

Write the equation for the statement as shown below,

106.45 × 1 + 8c = 163.25

Here c is the cost of one baseball,

Solve the above equation as shown below,

106.45  + 8c = 163.25

8c = 163.25 - 106.45

c = 56.8 / 8

c = 11.36

Thus, the cost of one baseball is $11.36.
