Split 33 into two numbers that when added up are 33.
So 12 to 21, which when divided by 3, are 4 to 7.

Answer:

Group #1: 12

Group #2: 21

Step-by-step explanation:

The ratio is 4:7 which means for each 4 elements in group number one we would have 7 elements in the group number 2. This gives us a total of 11 elements but the total is 33, so we do it again two more times to get the total of 33 elements (11x3=33) so now we know we have to multiply 3 times the ratio to get the correct answer like this

4(3):7(3)

12:21

Proof:

4+7=11

4+4+4=12

7+7+7=21

11+11+11=33

12+21=33

What’s the area of a rectangle measuring 13 inches times 12 inches ?

taurus [48]

Answer:

156 square inches

Step-by-step explanation:

We are given the two quantities

Let

length = l = 13 inches

and

Width = w = 12 inches

The formula for the area of rectangle is:

$Area=l*w$

where l is length and w is width

Putting the values of both that are given

$Area = 13*12\\=156$

so the area is 156 square inches ..

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. Four hu

castortr0y [4]

Answer: h = 120 ft; w = 80 ft

A = 9600 ft^2

Step-by-step explanation: Let h and w be the dimensions of the playground. The area is given by:

A = h*w (eq1)

The total amount of fence used is:

L = 2*h + 2*w + w (eq2) (an extra distance w beacuse of the division)

Solving for w:

w = L - 2/3*h = 480 - 2/3*h (eq3) Replacing this into the area eq:

We derive this and equal zero to find its maximum:

Solving for h:

h = 120 ft. Replacing this into eq3:

w = 80ft

Therefore the maximum area is:

A = 9600 ft^2

Please help me!!!You will get 20 points...

Use the rule of 3, note that we will convert the hours to minutes:

60 - 84
75 - x

(75 * 84) / 60 = x
6,300 / 60 = x
105 = x

105 minutes = 1h 45m

Hope it helped,

Happy homework/ study/ exam!
