Answer:

22.5 cm, 30 cm, 37.5 cm

Step-by-step explanation:

Sum the parts of the ratio, 3 + 4 + 5 = 12 parts

Divide the perimeter by 12 to find the value of one part of the ratio.

90 cm ÷ 12 = 7.5 cm ← value of 1 part of the ratio, thus

3 parts = 3 × 7.5 cm = 22.5 cm

4 parts = 4 × 7.5 cm = 30 cm

5 parts = 5 × 7.5 cm = 37.5 cm

The 3 sides are 22.5 cm, 30 cm and 37.5 cm

Answer:

y= -2/3x + 4

Step-by-step explanation:

2x + 3y = 12

3y = 12 - 2x

3y/3 = 12/3 - 2x/3

y = 4 -2x/3

y = -2x/3 + 4

Answer: The population is 730 and the sample is 102.

Step-by-step explanation:

When we have a given set of elements, N elements, the population is N.

And if we do statistics with A of these N elements, the sample is A.

In this case, the population is the set of the 730 drivers, then the population is 730.

And while 200 of them are randomly selected, we can only work with 102 of them (because we have only 102 returned questionnaires).

Then the sample will be 102.

Then the correct option is:

The population is 730 and the sample is 102.

Answer:

730 and 102.

I took the test, so I know this is the correct answer.

Answer: 5 or 9

Find the factors of the number 45.

1, 5, 9, 15

The numbers must be greater than 1 and less than 10.

Now, we must take 5 and 9.

5 x 9 = 45

9 x 5 = 45

The answers are 5 & 9.

Answer: 5, 9

Factors of 45:

5 and 9 are between 1 and 10.

They are the answers.

5 x 9 = 45

9 x 5 = 45

Step-by-step explanation:

You can also solve this algebraically:

–5 – (–3)

–5 + 3

–2

Since it can't be negative units between two points on a number line, you can multiply it by –1 to make it a positive number:

–2 (–1)

2 units

Or, you can use a number line. I have screenshotted a number line attached below for you.

Answer: B

Step-by-step explanation:

We have to find the amount that Maya painted IN ALL, which means we must add 3/4 and 1/8. First, look for the answer choice that has 1/8 as a number (B and A). However, none of the answer choices have 3/4 as an answer, so we must convert it into an equivalent fraction, 6/8. You get 6/8 by multiplying both the numerator and denominator by 2. Therefore the answer is B.

Answer: 13 minutes

Step-by-step explanation: common sence every minute the heart beats 25 times so 25 times 3 equals 75 so if that s true then 25 times 13 equals 325 ;)

Answer:

Step-by-step explanation:

It is 12.99 - 13 min. because 325 divided by 75

equals 4.33 and so on. If you times 4.33 by 3

you get 12.99, if your teacher said to round it

then do 13 Min. Hope this helps! <3

The value of the x should be more than or equal to 5.69. Then the correct option is A.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is used to compare two statements.

A school is planning a fundraiser with all profits going to charity.

Ticket Sales: 200x − 10x²

Event Cost: 500 + 20x

The amount of profit is found by subtracting the total cost from total ticket sales. A profit of $200 or more.

             Event cost − Total sales  ≥ Profit

         (500 + 20x) − (200x − 10x²) ≥ 200

− 200x + 10x² + 500 + 20x − 200 ≥ 0

                         10x² + 180x − 700 ≥ 0

                         10x² − 180x + 700 ≥ 0

                                  x² − 18x + 70 ≥ 0

On simplifying, we have

(x − 5.69) (x − 12.33) ≥ 0

                               x ≥ 5.69, 12.33

Thus, the value of the x should be more than or equal to 5.69. Then the correct option is A.

Answer:

Answer:

(5, 20)  

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

   = (40-0)/(10-0)

   = 40/10

   =4

Since the line goes through (0,0) the y intercept is 0

y = mx+b

y = 4x

Lets check the points  by substituting into the equation

40, 10)     10 = 4*40   10 =160  no

(–5, –10)    -10 = 4*-5    10 = -20   no

(5, 20)       20 = 4*5    20 = 20  yes

(–10, –20)    -20 = 4*-10    -20 = -40   no

Answer:

Step-by-step explanation:

Answer:

13

Step-by-step explanation:

replace the numbers given for each variable: 7(2)=14+(-1)=13

Step-by-step explanation:

Hey there!

Given;

The equations are;

y = 8x...........(i)

y = 2x-12..........(ii)

Now;

Substituting the value of "y" from equation (i).

8x = 2x-12

8x-2x = -12

6x = -12

X = -12/6

Therefore, X= -2.

Now; Substituting the value of "y" in equation (i)

y = 8*-2

y = -16

Therefore, y= -16.

Therefore, x= -2 and y= -16.

Check:

y = 2x

-16= 8*-2

-16 = -16 (true).
