Which number is a solution of the inequality? Choose one:

-3x(10-x)>4

a. 2
b. -3
c. 1
d. 0

Look at the picture.

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

[tex]\dfrac{DC}{ZX}=\dfrac{DY}{ZY}[/tex]

DC = x

ZX = 16

DY = a

ZY = a + a = 2a

Substitute:

[tex]\dfrac{x}{16}=\dfrac{a}{2a}[/tex]

[tex]\dfrac{x}{16}=\dfrac{1}{2}[/tex]       multiply both sides by 16

[tex]\boxed{x=8}[/tex]

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:

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:

7.10

Step-by-step explanation:

163.25- 106.45

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.

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:

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:

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

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.

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.

Step-by-step explanation:

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.

Answer:

Step-by-step explanation:

slope = [tex]\frac{change in y}{change in x}[/tex] = [tex]\frac{3}{1}[/tex]

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)

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.
