Answer:

12.5% (I think)

Step-by-step explanation:

75 is the amount of money lost, and 75 is 12.5 percent of 600

Answer:

12.5 percent decrease

Step-by-step explanation:

Use the formula

new-old/old

525 is new price being sold

600 is old price being sold

525-600

-75/600

-1/8

-1/8= -0.125

0.125= 12.5 percent

so 12.5 percent decrease.

Answer:

A.43.0

Step-by-step explanation:

area of rectangle= l*w=10 units *20 units= 200 units^2

area of the 2 circles:

diameter= 20/2=10 units

r=d/2= 10/2=5 units

area of a circle= 3.14*r^2

=3.14*5*5

=78.5> the 2 circles are identical then they have the same area

area of the shaded region= area of the rectangle- 2*area of one circle

= 200- (2*78.5)

=200-157

=43.0

therefore the area of the shaded region is 43.0 units^2

Answer:

x = -3, x = 7

Step-by-step explanation:

( 5x + 15 ) ( x - 7 ) = 0

5x + 15 = 0

5x = -15

x = -3

x - 7 = 0

x = 7

Answer:

x=−3 or x=7

Step-by-step explanation:

(5x+15)(x-7)=0

5x2−20x−105=0

5(x+3)(x−7)=0

x+3=0 or x−7=0

x=−3 or x=7

Answer:

30-60-90 degrees

Step-by-step explanation:

1st angle:  x

2nd angle:  3x

3rd angle:  x+30

Sum of all angles must be 180 degrees

x + 3x + x + 30 = 180

5x + 30 = 180

5x = 150

x = 30

Answer:

60 inches

Step-by-step explanation:

Mark: 52 inches

Bryan: x Inches

X: 52 + 8

52 + 8 = 60

x= 60

Bryan: 60 inches

because mark is 8 inches shorter so bryan is 8 inches taller.

For ΔKXD, x = 21

"The triangles that have corresponding sides in proportion to each other and corresponding angles are equal."

For given question,

ΔAGM is similar to ΔKXD

This means,

[tex]\frac{AG}{KX} = \frac{GM}{XD} = \frac{AM}{KD}[/tex]

Consider,

⇒ [tex]\frac{AG}{KX} = \frac{GM}{XD}[/tex]

⇒ [tex]\frac{32}{x+3} = \frac{36}{x+6}[/tex]

⇒ [tex]32\times (x+6) = 36\times (x+3)[/tex]

⇒ [tex]32x+192=36x+108[/tex]

⇒ [tex]4x = 84[/tex]

⇒ x = 21

Answer:

1.5 grams per tablespoon

Answer:

I will try my best. Don't really know if this is correct.

Step-by-step explanation:

Well, first, you will have to get a mixed number, 9/2. And then divide 9/2 to 3/1. ( 9/2 divided by 3/1 = ? ) Then, multiply the equation. ( ? x 3 = 9/2 )

Last, draw a diagram to represent the answer.

9/2 = ? ? ? (Pretend that is a diagram) ? = 3/2 gallon

You will have to simplify the answer to get 3/2 gallon.

Look, I tried my best trying to explain everything, this question is very confusing and hard to do.

Answer:

x=30

y=4

Step-by-step explanation:

Since there is an equilateral triangle, those angles =60°, and all sides to that triangle are equal.

You can determine y by looking at the congruent lines on the second triangle. In this triangle, we see that two sides, one of which is a side to the equilateral triangle, are equal to 20. Because one of these sides is a side to the equilateral, we know that all sides of the equilateral triangle are equal to 20, so using simple algebra you can determine that y=4.

To solve for x is a little more difficult. In the equilateral triangle, we know that all angles =60°, therefore we can solve for two angles to use to solve for x. We can solve for the obtuse angle by subtracting 60 from 180=120. then we can solve for the next angle that is next to the equilateral triangle because these two make a right angle so 90-60=30. Now you add the angles you just solved for, subtract that sum from 180, and you get x.

120+30=150

180-150=30

x=30

Answer:

vertical asymptote X=-1

horizontal asymptote Y=2

Step-by-step explanation:

The vertical and the horizontal asymptotes of the function [tex]f(x) = \frac{2x^2 +7x - 4}{x^2 + 5x + 4}[/tex] are x = -1, and y = 2

The function is given as:

[tex]f(x) = \frac{2x^2 +7x - 4}{x^2 + 5x + 4}[/tex]

To start with, we plot the graph of f(x)

The asymptotes are the lines that pass through the points that appears to be on the curve because of their nearness to the curve, but they are actually not on the curve of the function.

From the graph (see attachment), we can see that:

The vertical and the horizontal asymptotes are x = -1, and y = 2

[tex]5(56z - 5y - 6)[/tex]

Step-by-step explanation:

Forst step is finding a common factor, you can do this easily by looking at the ones digit. All 3 values end in 0 or 5, so a factor is definately 5.

We now divide all values by 5.

[tex]280z \div 5 = 56z \\ (- 25y) \div 5 = ( - 5y) \\ ( - 30) \div 5 = ( - 6)[/tex]

Once you get a prime number after factoring, that is the GCF, Greatest Common Factor. We can make an equation like what is below to show oir factored answer.
