please help i need to solve for m and n

Answer:

1) 36

2) 190

3) 72 units

Step-by-step explanation:

1)  2x4 = 8 units area for rectangle

(4-2) x4 /2 = 4 units

6 x 4 = 24 units

8 + 4 + 24 = 36

2) 3 x 10 / 2 = 15 units

   5 x 10 /2 = 25 units

   15 x 10 = 150 units

   150 + 25 + 15 = 190 units

3) 6 x 3 / 2 = 9 units

   6 x 9 = 54 units

   6 x 3 / 2 = 9 units

9 + 9 + 54 = 18 + 54 = 72 units

All students in each grade

audience: students - counts for both boys and girls.

option (B) for teachers is irrevelant.

option (C) doesn't include girls.

option (D) doesn't include the entire school

Hence, option A is correct.

Answer:

V= pi multiplied by radius squared multiplied by height

7² = 49

49 x 10 = 490

V= 490[tex]\pi[/tex]

Answer:

The percent of decrease is 33.3... percent

Step-by-step explanation:

9 - 6 = 3

3 ÷ 9 = 0.3...

0.3... x 100 = 33.3...

The percent of decrease in student absences this year is 33.33%

The percentage is a fraction or a ratio in which the value of the whole denominator is always 100.

Given that the average number of absences in schools was 9 students per day.

This year the average number is 6 students per day.

We need to find the percent of decrease in student absences this year,

So, the percentage of decrease = 9 - 6 / 9 × 100%

= 1/3 × 100

= 33.33%

Hence the percent of decrease in student absences this year is 33.33%

Answer:

96.2+240.5/x

Step-by-step explanation:

g(x)=96.2(4)(x+2.5)

h(x)=[96.2(x+2.5)](4)--------------Calculate[96.2(x+2.5)] first

h(x)=(96.2x+240.5)(4)

h(x)=x(96.2+240.5/x)(4)----------bring out X,So 96.2x+240.5 is divided by x

h(x)=(96.2+240.5/x)(4)x

h(x)=a(4)x

so a=96.2+240.5/x

The value of a is 96.2 + 240.5/x.

A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain. The usual way to refer to a function is as f(x), where x is the input. A function is typically represented as y = f. (x).

Given g(x) = 96.2(4)(x+2.5),

and h(x) = a(4)x,

to find a

h(x) = [96.2(x + 2.5)](4)--------------Calculate[96.2(x+2.5)] first

h(x) = (96.2x + 240.5)(4)

h(x) = x(96.2 + 240.5/x)(4)--------bring out x,So 96.2x+240.5 is divided by x

h(x) = (96.2 + 240.5/x)(4)x

h(x) = a(4)x

so a  = 96.2 + 240.5/x

Hence value of a  = 96.2 + 240.5/x

Answer:

B. 75 mph

Step-by-step explanation:

d - distance

v - velocity

t - time

d = 120 miles

t = 2 hrs

1st 60 miles :

[tex]v = \frac{d}{t} [/tex]

[tex]t = \frac{d}{v} [/tex]

[tex]t = \frac{60}{50} [/tex]

[tex]t = 1.2 \: hrs[/tex]

[tex]t = 1.2 \times 60[/tex]

[tex]t = 72 \: minutes[/tex]

2nd 60 miles:

It took 72 minutes for him to travel the first 60 miles. To get the remaining time:

[tex]t = 120 - 72[/tex]

[tex]t = 48 \: minutes[/tex]

[tex]t = 0.8 \: hrs[/tex]

For the Velocity:

[tex]v = \frac{d}{t} [/tex]

[tex]v = \frac{60}{0.8} [/tex]

[tex]v = 75 \: mph[/tex]
