Given A = ½ (b₁ + b₂)h<br><br> Solve for h
mihalych1998 [28]

Answer:

h = (2 A)/(b_1 + b_2)

Step-by-step explanation:

Solve for h:

A = 1/2 h (b_1 + b_2)

A = 1/2 h (b_1 + b_2) is equivalent to 1/2 h (b_1 + b_2) = A:

1/2 h (b_1 + b_2) = A

Divide both sides by 1/2 (b_1 + b_2):

Answer:  h = (2 A)/(b_1 + b_2)

Write a problem situation for this inequality 72-12a&lt;24
Morgarella [4.7K]

Answer:

Subtracted 12 times a number from 72 is less than 24.

Step by step solution

Given inequality is 72-12a

We need to write in word.  

12a means 12 times a number “a”

72-12a means subtract 12a from 72.

72-12a<24 means result is less than 24.  

Inequality shows “Subtracted 12 times a number from 72 is less than 24”

If we solve for number “a”

-12a<24-72

-12a<-24

a>2

All the number greater than 2 satisfy the given inequality.

The average age of 40 students of a class is 15 years. An 18 year-old student left the class and a new student was admitted. As
cluponka [151]

Answer:

Answer:age of new student is 13.4 years

Step-by-step explanation:

SUM of ages all 40 students =average age times 40

=15*40=600

after leaving 18 years old student

SUM of ages of 39 students will be 600-18=582

after adding new student with age x

SUM of ages of 40 students will become 582+x

and the average would be (582+x)/40

which is given as 14.885

so we get equation

(582+x)/40=14.885

582+x=14.885*40=595.4

x=595.4-582

x= 13.4

age of new student is 13.4 years

Hope it will help you
