Answer:

[tex]\frac{BC}{KL}[/tex] = [tex]\frac{AD}{JM}[/tex]

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion , that is

[tex]\frac{BC}{KL}[/tex] = [tex]\frac{AD}{JM}[/tex]

Answer:

Divide it by 2 then multiply it by the answer. For example b is 4, divide it by 2. Then multiply by itself which is 2. Then answer is 4.

Answer:

The P versus NP problem is a major unsolved problem in computer science. It asks whether every problem whose solution can be quickly verified can also be solved quickly.

P is the set of problems whose solution times are proportional to polynomials involving N's. ... NP (which stands for nondeterministic polynomial time) is the set of problems whose solutions can be verified in polynomial time. But as far as anyone can tell, many of those problems take exponential time to solve.

Answer:

20.4

Step-by-step explanation:

The formula to find the volume of a rectangular prism is :

Given that,

Volume = 8223.75 in³

length = 12.5 in

width = 32.25 in

height = ?

Now let us use the formula and find the height.

V = l × w × h

8223.75 = 12.5 × 32.25 × h

8223.75 = 403.125h

Divide both sides by 403.125.

20.4 = h

Therefore,

height = 20.4 in

y=7/4x-3 or y=1.75x-3

it will go downwards left t right (negative slope) and pass through the y intercept at (0,3)

Answer:

A

Step-by-step explanation:

The answer to your question is 17/24

First find the lcd which is 24

5/8 = Times eight by three to get 23 = And whatever you do to the top you do to the bottom = So then you would do five times three to get 15 = To create your new fraction 15/24

1/12 = Times twelve by two to get 24 = And whatever you do to the top you do to the bottom = So then you would do one time two to get 2= To create your new fraction 2/24

Then you would add 15/24+2/24= 17/24

Answer:

15

Step-by-step explanation:

Answer:

C. There is a $2 fee to park, before the number of hours are factored in.

Step-by-step explanation:

Given that the equation, [tex] y = 3x + 2 [/tex], represents total cost charged for at a parking lot for customers to park their car, thus:

the "x" represents the number of hours,

3 represents the charged fee per hour

2 represents the flat fee charged, which is the starting fee, before the number of hours is calculated and added.

Therefore, the answer is "C. There is a $2 fee to park, before the number of hours are factored in."

Answer:

$9

Step-by-step explanation:

6(x-2)=42

x-2=7 (divide by 6 on both sides)

x=9 (add 2 to both sides)

Answer:

2x² + 6x - 20

Step-by-step explanation:

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

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

A = 2x² + 10x - 4x - 20

A = 2x² + 6x - 20

Step-by-step explanation:

75% of students pack their lunch. 3/4 as a decimal is 0.75. 0.75 as a percentage is 75%.

-hope it helps

Answer: 75%

Use division to convert the fraction to a decimal: 3/4 = 3 ÷ 4 = 0.75.

Multiply by 100 to get percent value: 0.75 × 100 = 75%

Answer:

24

Step-by-step explanation:

12 + 12 = 24

Answer:

it is 24

Step-by-step explanation:

The probability that the student was male, given the student chose to fly as their superpower is 2/3.

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell by the total frequency.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have:

Total females = 48

Females and invisibility = 32

P(invisibility/female) = 32/48

= 2/3

Thus, the probability that the student was male, given the student chose to fly as their superpower is 2/3.

Answer:

You should multiply 5.5 by 7 and it is equal to 38.5 so it is D

explanation:

did the test hope this helps! :D

The constant of proportionality of the given condition is 5.5.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

Let's say Matthew and Rosa's constant of proportionality is K.

Now,

Matthew bought 2 movie tickets for $11.

So,

11 ∝ 2

11 = K 2 ⇒ K = 5.5

Now,

Rosa bought 7 movie tickets for $38.50.

So,

38.50 ∝ 7

38.50 = K 7 ⇒ K = 5.5

Hence "The constant of proportionality of the given condition is 5.5".

Answer:

Part A:

10ft

Part B:

35ft

Step-by-step explanation:

• Since we know that an increase of 1 on either the x, or y value is equal to 5 feet, we can form an equation where x = the amount that the value increased, so since the fountain is at (-2, -2) and the slide is at (-2, 0), we see that there is an increase of 2 to the y-value, meaning our equation should now be 5(2) which equals 10.

• Because we use 5x and 5y to solve this, we can already see how to do this. If the swings are at (5, -2) and the fountain is at (-2, -2), we can see that there was an increase of 7 on the x-value, meaning that our equation would now be 5(7), which equals 35.

▪ Answer:

n = 17

d = 8

▪ Step-by-step explanation:

Hi there !

1 nickel = 5c

1 dime = 10c

$1.65 = 165c

n + d = 25 => n = 25 - d

5n + 10d = 165

replace n

5(25 - d) + 10d = 165

125 - 5d + 10d = 165

5d = 165 - 125

5d = 40

d = 8 (dimes)

n = 25 - d

n = 25 - 8

n = 17 (nickels)

Answer:

y = 6x + 4

Step-by-step explanation:

We know the equation is linear.  First, use two points to find the slope of the line.

m = (y₂ − y₁) / (x₂ − x₁)

m = (10 − 4) / (1 − 0)

m = 6

The y-intercept is 4.  So the equation of the line is:

y = mx + b

y = 6x + 4

Answer:

Slope (M) 5.000000
