Answer:

5) 1/3=x/12

12=3x

3x=12 (divide both sides)

12 divided by 3 = 4

therefore, x = 4

6) 5/9=25/y (cross multiply the numbers)

after cross multiplying you should get: 5y=225

divide both sides to get 45

therefore, y = 45

7) 26/z = 13/22 (cross multiply numbers)

after cross multiplying, you should get: 572=13z (swap the numbers)

after swapping the number, you should get: 13z=572 (divide both sides)

after dividing you should get 44

therefore, z = 44

8) b/30 = 2.6/1.5 (simplify expression)

after simplifying you should get: b/30=26/15 (cross multiply after)

after cross multiplying you should get: 15b = 780 (divide both sides)

after dividing both sides, you should get: 52

therefore, b = 52

Hope this helps:)!

the boys that will play the match are 2/7 of boys = (2/7)x35 = 10 boys

You deposit $1295 dollars in a mutual fund that provides an average return of 8.4% interest compounded annually.
Orlov [11]

Answer: $2,277.5

Step-by-step explanation:

Hi, to answer this question we have to apply the compounded interest formula:

A = p (1+ r )^t

A = total amount (principal plus returns)

P = principal invest

r =interest rate (decimal form)

t = time (in this case years)

Replacing with the values given:

A = 1295 (1 + 8.4/100)^7

A = 1295 ( 1+ 0.084)^7

A = 1295 ( 1.084)^7

A = 2,277.5

A trapezoid with a right angle and an area greater than 40 square inches
andreev551 [17]

Answer:

see the attached figure.

Step-by-step explanation:

We need to draw a trapezoid with a right angle and an area greater than 40 square inches

See the attached figure

The area of the trapezoid = 0.5 ( base_1 + base_2 ) * height

So, as shown ABCD is a trapezoid with a right angle at A

base_1 = 14 inches , base_2 = 10 inches and the height = 5 inches

So, the area = 0.5 ( 14 + 10 ) * 5 = 0.5 * 24 * 5 = 60 square inches > 40

Note: we can use any numbers other than 5 , 10 , 14

for example: 5 , 8 , 12 in this case the area = 0.5 * (8+12) * 5 = 50 > 40

<u>The point is choose any numbers which gives area > 40</u>
