Answer:

see the explanation

Step-by-step explanation:

we know that

A mixed number is equal to sum a integer plus a fraction less than 1. The result is a fraction where the numerator will be always greater than the denominator (This fraction is called an improper fraction)

Example

a\frac{b}{c} ----> a mixed number

a is a integer

b/c < 1

so

a\frac{b}{c}=a+\frac{b}{c}

Adds the integer plus the fraction

\frac{ac+b}{c} ---> an improper fraction

\frac{ac+b}{c} > 1

what is the surface area of a rectangular prisim with a base length of 9 yd, base width of 7 yd,and a height of 4 yd?
krek1111 [17]

Answer:

254 yds²

Step-by-step explanation:

There are 6 faces of the prism we need to calculate the area of for a rectangular prism.

The base and top of the prism measure 9x7 yards each, so there are two faces with an area of 63 yds²                 (9 x 7 = 63)

The sides of the prism measure 4x7 yards each, so there are two faces with an area of 28 yds²    (4 x 7 = 28)

The front and back face of the prism measure 9x4 yards each, so there are two faces with an area of 36 yds²     (9 x 4 = 36)

The total surface area is

2(63) + 2(28) + 2(36) = 254 yds²

Radius of a circular ground is 21m. Find.
trapecia [35]

The circumference of a circle of radius r is

C=2\pi r

So, in your case, the circumference is

C=2\cdot \pi \cdot 21 = 42\pi

The circumference is actually the length of the "perimeter", so the answer to questions 1 and 2 looks the same actually
