Answers

Answer and explanation:

1. 15 girls to 6 boys = 15:6

15/6= 5/2

2. 24 players to 3 teams = 24:3

24/3= 8/1=8

3. 48 worksheets to 12 students =48:12

48/12= 4/1

4. 4/7 and 24/35 are not proportional as they do not reduce to same ratio

5. 11/12 and 33/36 are proportional because they reduce to same same ratio(33/36=11/12)

6. 8/24 and 5/15 are proportional beacaue they reduce to same ratio(8/24=5/15=1/3)

7. 3/7 and 12/21 are not proportional because they do not reduce to same ratio(3/7≠12/21)

8. 25 cars in 5 days= 25/5= 5 cars each day. 60 cars in 12 days = 60/12=5 cars each day. Therefore they are proportional.

9. 14 books in 2 boxes= 7 books per box. 20 books in 3 boxes = 20/3= 6.667. Therefore they are not proportional.

10. 12 laps in 30 minutes =12/30=2/5

15 laps in 45 minutes =15/45=1/3. Therefore they are not proportional.

Step-by-step explanation:

The two sides of the triangle are around the angle

The similarity theorem that identifies the given relationship correctly would be:

B). AABC - ADEF by SAS Similarity Theorem

What is SAS Similarity?

The SAS similarity Theorem state that in the situation where the ratio shared by the sides of two triangles remains the same and one of their angles stays equal, both the triangles would be similar.

In the given two triangles,

ΔABC and ΔDEF

The ratio of the sides are:

[tex]\frac{BC}{AB} = \frac{EF}{DE}[/tex]

so,

[tex]\frac{5}{15} = \frac{4}{12} = \frac{1}{3}[/tex]

and,

∠B = ∠E = 86°

Since the ratios shared by the two sides are equal in both the given triangles and one angle is equal, the triangles are the same.

Thus,

ΔABC ~ ΔDEF

Find the mid segment of GH

Answers

Answer:

B. 2

Step-by-step explanation:

Based on the Midsegment of a trapezoid theorem:

GH = (BC + FE)/2

9x - 3 = (19 + (5x + 1))/2) (substitution)

9x - 3 = (20 + 5x)/2

Cross multiply

2(9x - 3) = 20 + 5x

18x - 6 = 20 + 5x

Collect like terms

18x - 5x = 20 + 6

13x = 26

Divide both sides by 13

x = 26/13

x = 2

A bag contains 4 green marbles, 3 red marbles, and 7

blue marbles. One marble is taken from the bag and put

back after checking its color. A second marble is then

taken out. What is the probability that the first is blue

and the second red?

Answers

Answer:

3/28

Step-by-step explanation:

There are 14 marbles in the bag. So, the probability of choosing a blue marble is 7/14 or 1/2. Since the first marble is replaced, the bag still has 14 marbles in it. Then the probability of choosing a red marble is 3/14. The probability of choosing the blue, then the red is 1/2 x 3/14 = 3/28

120 - 20 =

1. Subtract 0 by 0.

0 - 0 = 0

2. Subtract 2 by 2.

2 - 2 = 0

3. Since there isn't a number in the hundred's place, bring the 1 down.

Therefore, your answer is: 100. There are 100 blonde-haired girls.

In one classroom their is about 25% people that are blonde, so in 6 classes with 20 people each their would be 30 blonde haired girls.

what is the inverse of f (x) = −(x+1)^2+4

Answers

Step-by-step explanation:

To find the inverse function, swap x and y, and solve the resulting equation for x.

If the initial function is not one-to-one, then there will be more than one inverse.

So, swap the variables: y=4−(x+1)2 becomes x=4−(y+1)2.

Now, solve the equation x=4−(y+1)2 for y.

I have to determine whether the sides of the triangle form a pythagorean triple.

Answers

Answer:

Step-by-step explanation:

How do you know if side lengths form a Pythagorean triple?

Pythagorean triples may also help us to find the missing side of a right triangle faster. If two sides of a right triangle form part of a triple then we can know the value of the third side without having to calculate using the Pythagorean theorem. From the ratio, we know that it is a Pythagorean triple.

Answer:

I'm learning this too the answer is 12x+10y10

slope-intercept form: y = mx + b

we know what format we need to change the equation to.

subtract 12x to each side to get 10y alone.

12x - 12x + 10y = 100 - 12x

10y = -12x + 100

divide 10 to both sides to get y alone.

10/10y = -12/10x + 100/10

y = -6/5x + 10

y = -6/5x + 10 is your answer. i hope this helpes! let me know if i got something wrong that i need to fix.

If x + 2y = 9 and 3x - y = -8, what is the value of (2x+y)?

Answers

Answer:

The value of (2x+y) is 3.

Step-by-step explanation:

First, we have to find the values of x and y.

We have that:

x + 2y = 9, which also means that:

x = 9 - 2y

Replacing into the second equation, to find y:

[tex]3x - y = -8[/tex]

[tex]3(9 - 2y) - y = -8[/tex]

[tex]27 - 6y - y = -8[/tex]

[tex]7y = 35[/tex]

[tex]y = \frac{35}{7}[/tex]

[tex]y = 5[/tex]

Finding x:

[tex]x = 9 - 2y = 9 - 10 = -1[/tex]

What is the value of (2x+y)?

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

The value of (2x+y) is 3.
