8. Jack has twice as many dimes as quarters. If the total
value of the coins is $6.30, how many dimes does he
have?

Answers

Answer 1

Answer:

Step-by-step explanation:

d=2q, q=d/2

10d+25q=630, using q=d/2

10d+25d/2=630

20d+25d=1260

45d=1260

d=28

So he has 28 dimes.

fine the lowest common multiple of90 and 150

Answers

Answer: 450

Step-by-step explanation:

Find the prime factorization of the two numbers (using a factor tree)

90 = 2 * 3 * 3 * 5

150 = 2 * 3 * 5 * 5

(The common factors are bolded)

To find LCM, multiply all the factors from the two prime factorizations

However, only multiply the common ones once

2 * 3 * 3 * 5 * 5 = 450

Ben is rock climbing in the Grand Canyon. He starts off 59.3 feet above sea level and descends into the canyon. The difference between his starting and ending elevation is 129.6 feet. What is Ben's final elevation?

Answers

Answer: -70.3 feet

Step-by-step explanation:

Let Ben's final elevation be represented by x.

We are informed that he starts off 59.3feet above sea level and descends into the canyon and that the difference between his starting and ending elevation is 129.6 feet. This will then be expressed in an equation as:

59.3 - x = 129.6

x = 59.3 - 129.6

x = -70.3

Therefore, the final elevation is -70.3 feet.

The Length of a rectangle is twice the with the area of the rectangle is 90 square units know that you can divide the rectangle into two squares which number represents the length of each side of the Squares

Answers

Answer:

2√45units

Step-by-step explanation:

Area of the rectangle = Length × Width

A = LW

If the Length of a rectangle is twice the width, then;

L = 2W

A = 2W(W)

Since area = 90

90 = 2W²

W² = 45

W = √45

Get the length

L =2W

L = 2√45 units

Hence the length of square is 2√45units

Step-by-step explanation:

First let's find the slope of the line through the points  and  

Note:  is the first point . So this means that x%5B1%5D=-2 and y%5B1%5D=0.

Also,  is the second point . So this means that x%5B2%5D=0 and y%5B2%5D=3.

m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29 Start with the slope formula.

m=%283-0%29%2F%280--2%29 Plug in y%5B2%5D=3, y%5B1%5D=0, x%5B2%5D=0, and x%5B1%5D=-2

m=%283%29%2F%280--2%29 Subtract 0 from 3 to get 3

m=%283%29%2F%282%29 Subtract -2 from 0 to get 2

So the slope of the line that goes through the points  and  is m=3%2F2

Now let's use the point slope formula:

y-y%5B1%5D=m%28x-x%5B1%5D%29 Start with the point slope formula

 

y-0=%283%2F2%29%28x--2%29 Plug in m=3%2F2, x%5B1%5D=-2, and y%5B1%5D=0

y-0=%283%2F2%29%28x%2B2%29 Rewrite x--2 as x%2B2

y-0=%283%2F2%29x%2B%283%2F2%29%282%29 Distribute

y-0=%283%2F2%29x%2B3 Multiply

y=%283%2F2%29x%2B3 Simplify

So the equation that goes through the points  and  is y=%283%2F2%29x%2B3

Notice how the graph of y=%283%2F2%29x%2B3 goes through the points  and . So this visually verifies our answer.

Graph of y=%283%2F2%29x%2B3 through the points  and
