Answer:

2 1/8

Step-by-step explanation:

7/8 is the same as 0.875 and therefore you need 0.125 also known as 1/8 to make it a whole number. When you add it to the already existing whole 2 you get three. Subtract three from five to make two which is what you need to add on top to finally get 5.

Find the annual percentage rate of change for the population of Oregon. In 2000, there were 4.8

MrRa [10]

Answer:

The annual percentage rate of change for the population of Oregon is of 8.125%.

Step-by-step explanation:

Total percentage change:

Change multiplied by 100 and divided by the initial value.

Change: 8.7 - 4.8 = 3.9 million

Initial value: 4.8

Percentage change: 3.9*100/4.8 = 81.25%

Annual percentage rate of change

81.25% during 10 years(from 2000 to 2010).

So, per year

81.25%/10 = 8.125%

The annual percentage rate of change for the population of Oregon is of 8.125%.

If the length of a leg of a triangle is 39.2 and the area of the triangle is 63 what is the length of the other leg

Nadya [2.5K]

Answer:

The length of the other leg is $3.21\ units$

Step-by-step explanation:

I will assume that the triangle is a right triangle

In a right triangle the legs are perpendicular

The area of a right triangle is equal to

$A=\frac{1}{2}(a)(b)$

where

a and b are the legs of the triangle

In this problem we have

$a=39.2\ units$

$A=63\ units^{2}$

substitute the values

$63=\frac{1}{2}(39.2)(b)$

$126=(39.2)(b)$

$b=126/(39.2)=3.21\ units$

Please help 40 POINTS

Nuetrik [128]

Answer:

To reduce a fraction: divide the numerator and denominator by their greatest common factor, GCF.

Fraction: 9/10 already reduced to the lowest terms.

The numerator and denominator have no common prime factors.

Their prime factorization:

9 = 32;

10 = 2 × 5;

gcf (32; 2 × 5) = 1;

Fraction: - 3/4 already reduced to the lowest terms.

The numerator and denominator have no common prime factors.

Their prime factorization:

3 is a prime number;

4 = 22;

gcf (3; 22) = 1;

LCM (10; 4) = 22 × 5 = 20

3/20 is the answer.........

a rectangular pool has an area of 640 square feet. the is 12 feet shorter than the width. the length of the pool is feet and the

Ray Of Light [21]

Given:

Area of rectangular pool = 640 square feet

The length is 12 feet shorter than the width.

To find:

The length and width of the pool.

Solution:

Let width of the pool = x feet

Then, Length of the pool = (x-12) feet

Area of a rectangle is

$Area=length\times width$

$Area=(x-12)\times x$

Area of pool is 640 square feet. So,

$(x-12)x=640$

$x^2-12x-640=0$

Splitting the middle term, we get

$x^2-32x+20x-640=0$

$x(x-32)+20(x-32)=0$

$(x+20)(x-32)=0$

Using zero product property, we get

$x=-20,32$

Dimensions cannot be negative. So, x=32.

Now,

Width of the pool = 32 feet

Length of the pool = 32-12 = 20 feet

Therefore, the length of the pool is 20 feet and width is 32 feet.
