Answer:

16/20=1/4

Step-by-step explanation:

James is 1/4 younger then his brother

4:5 is the ratio which  represents James' age to his brother's age 4 years from now.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that James is 12 years old

James  brother is 16 years old.

We need to find the ratio which represents James' age to his brother's age 4 years from now.

After 4 years the James age is 12+4, 16 years

After 4 years the James brother age is 16+4, 20years

The ratio of James' age to his brother's age is 16/20

4/5

Hence, 4:5 is the ratio which  represents James' age to his brother's age 4 years from now

Multiply the number of chairs by the price of the chair:

34 x 205 = 6,970

Total spent = $6,970

Answer:

Step-by-step explanation:

f(n)= -3n + 2

to find :f(12)

substitute 12 in place of n

f(12)= -3*12 + 2

f(12)=-36 + 2

f(12)= -34

The value of the  f(12) is equal to -46 where the expression is

f(n) = -3n + 2.

Any mathematical statement which consist of numbers , variables and arithmetic operations is known as expression. An expression gives some numerical value when we put the value of variables in it.

Here, f(n)= -3n + 2 is the given expression.

So, we can find the value of f(12) by putting n=12 in f(n).

Put n=12 in f(n), we get

          f(12)= (-3)×12 + 2

                 = -48 + 2

                 = -46

Hence, the value of f(12) is -46.

Answer: x=-10, y=-5 or -2/1. And it's dilated by 2. & i believe the scale factor is 2.

Step-by-step explanation:

What i did was simply count from the radius (the tiny dot in the center) up, and   i counted 3, and did the same w/ the A' so I got 6, why makes me assume the scale factor is 2. then i did rise/run and i went  10 left and 5 down. So that makes -10,-5.

Step-by-step explanation:

How to find it

Written using the formula: x = 66.50 ÷ 20%

Convert the percent to a decimal.

20% ÷ 100 = 0.2.

X = 66.50 ÷ 0.2.

So 20% of 66.60 is 13.3.

Answer:

7.5

Step-by-step explanation:

Median = middle number in terms of value

To make it easier to identify the middle number lets list the number from least to greatest

1, 4, 4, 7, 8, 8, 10, 15

Now we can simply find the middle number

We notice that there are two middle numbers as there is an even amount of numbers

Those two numbers being 7 and 8

When finding the median, if there are two middle numbers, you simply add the two numbers together and divide the sum by two to get the median.

So median = 8 + 7 = 15 / 2 = 7.5

Answer:

7.5

Step-by-step explanation:

The median of a set of numbers is the middle number, so we have to order them first from least to greatest. The order would be 1, 4, 4, 7, 8, 8, 10, 15. You can see that there are an even number of numbers, so if we take the two numbers in the middle of the order (7 and 8) and add them to get 15 and divide 15 by two, we get an answer of 7.5.

Answer:

a. 70 gallons of water were leaked each month.

Step-by-step explanation:

Set up an equation:

Variable x = gallons leaked each month

210/3 = x/1

Cross multiply:

210 × 1 = 3 × x

210 = 3x

Divide by 3 to isolate the variable:

70 = x

The division part is only 210 ÷ 3 = x. I wrote it down this way so you can see how I came to this equation.

Check your work:

210/3 = 70/1

210 × 1 = 3 × 70

210 = 210

Correct!

=====================================================

Work Shown:

7/20 = 0.35 = 35% of the 20 players made all five baskets.

If this trend holds up, then we should expect 35% of the 400 people to make all five baskets.

35% of 400 = 0.35*400 = 140

We expect about 140 people will make all five baskets.

Note how 140/400 = 0.35 = 35%

-------------

Through another alternative method, we can solve like this

7/20 = x/400

7*400 = 20*x ... cross multiply

2800 = 20x

20x = 2800

x = 2800/20 ... dividing both sides by 20

x = 140 which is the same result as before

(x + 2)(x + 5)

Step-by-step explanation:

Given

x² + 7x + 10

Consider the factors of the constant term (+ 10) which sum to give the coefficient of the x- term (+ 7)

The factors are + 2 and + 5 , since

5 × 2 = + 10 and 2 + 5 = + 7 , then

x² + 7x + 10 = (x + 2)(x + 5) ← in factored form
