1 answer:
romanna [79]2 years ago

Answer:

78

Step-by-step explanation:

for the right side we can just do 14*2 since there are two people per seat and 14 rows

14 *2 is 28

for the left side we just do 14*3 since there are three people per seat and 14 rows

14*3 is 42

Then we have to add the 8 students that can fit in the very back seat

42 + 28 + 8

28 + 8 is 36

42 + 36 = 78

The number a exceeds the number b by 50 percent. By what percent is the number b smaller than the number a?
inna [77]

Answer:

   33 1/3 percent smaller

Step-by-step explanation:


The number a exceeds the number b by 50 percent.

a = b + b*.5

a = b(1.5)

Divide by 1.5

a/1.5 = b

2/3a =b



We want to find (a-b)/a  to find the percent decrease

                           (a-2/3a)/a *100percent

                             (1/3a)/a* 100 percent

                                  1/3 * 100 percent

                                     33 1/3 percent smaller

What is the probability of rolling a 5 or not rolling a 5 using a regular 6-sided number cube?
Ne4ueva [31]
There are 6 different sides you can land on with a dice. So the probability of rolling any one side is 1/6. The probability of NOT rolling a 5 is the same thing as rolling anything except a 5. So that probability will be 5/6.

Could some please help and explain?
Sophie [7]

Answer:

x = 7

Step-by-step explanation:

A rhombus is a parallelogram where all sides are equal. Therefore, as we know two sides are equal to 7x+8 and 9x-6, we can say that

7x+8 = 9x - 6

subtract 7x from both sides to put the variable on one side

2x - 6 = 8

add 6 to both sides to isolate the variable and its coefficient

2x = 14

divide both sides by 2 to isolate x

x = 7
