Answer:

[tex] EF = 5 [/tex]

[tex] GH = 5 [/tex]

Step-by-step explanation:

Length of EFis the distance between E(-4, -3) and F (-1, 1).

[tex] EF = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] E(-4, -3) = (x_1, y_1) [/tex]

[tex] F(-1, 1) = (x_2, y_2) [/tex]

[tex] EF = \sqrt{(-1 -(-4))^2 + (1 -(-3))^2} [/tex]

[tex] EF = \sqrt{(3)^2 + (4)^2} [/tex]

[tex] EF = \sqrt{9 + 16} = \sqrt{25} [/tex]

[tex] EF = 5 [/tex]

Distance between G(-2, -3) and H(3, -3)

[tex] GH = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] G(-2, -3) = (x_1, y_1) [/tex]

[tex] H(3, -3) = (x_2, y_2) [/tex]

[tex] GH = \sqrt{(3 -(-2))^2 + (-3 -(-3))^2} [/tex]

[tex] GH = \sqrt{(5)^2 + (0)^2} [/tex]

[tex] GH = \sqrt{25 + 0} = \sqrt{25} [/tex]

[tex] GH = 5 [/tex]

Answer:

approximately 1.213 billion gallons of fuel will be saved per year.

Step-by-step explanation:

Distance to the store = 1/2 mile

If my car gets 30 miles to one gallons, then for 1/2 mile my car will use

1/2 ÷ 30 = 1/2 x 1/30 = 1/60 gallons

Statistics puts the number of cars users on Earth to be about 1.4 billion = 1.4 x 10^9 cars

If every driver makes this decision once a week for a year, that will be 52 times a year since there are 52 week in a year.

Total gas that will be saved in one week = 1/60 x 1.4 x 10^9 = 23333333.3 gallons

In a year that will be = 23333333.3 gallons x 52 = 1.213 x 10^9 gallons

that is approximately 1.213 billion gallons of fuel saved per year

Answer:

1/2+1/5=7/10

Step-by-step explanation:

1/2=5/10

1/5=2/10

2/10+5/10=7/10

Answer:

0.7 or 7/10

Step-by-step explanation:

When adding fractions they always need to have the same denominators,and the one they both have similar to is being equal to 10.

1/2 will get multiply with 5 on the numinator and the denominator having you get a fraction of 5/10.

You will do the same with 1/5 multiply it with 2 on the numinator and denominator having you get  5/10.

Since the dneominators are the same you keep it 10,and just add 5 and 2. Giving you a answer of 7/10

Answer:

7 + 2 × a.

Step-by-step explanation:

Take a as the number.

Twice the number means 2 multiplied by the number.

More than means addition.

So, it would be 7 + 2 × a.

It's an equation.

Answer:

h(-67) = 3158

Step-by-step explanation:

Simply plug in -67 for x:

h(-67) = -49(-67) - 125

h(-67) = 3283 - 125

h(-67) = 3158

Answer: h(-67) = 3158

Step-by-step explanation:

-49(-67)-125

3283-125

3158

Answer:

3/2

Step-by-step explanation:

Given the equation 3/2(4x-2)-3x = 5-(x+2)

Open the parenthesis

3/2(4x) - 3/2(2) -3x = 5-x-2

6x-3-3x = 3-x

3x-3 = 3-x

Collect like terms

3x+x = 3+3

4x = 6

Divide both sides by

4x/4 = 6/4

x = 3/2

Hence the value of x is 3/2

Step-by-step explanation:

x ≥ -8

Answer choice D is correct

x ≥ -8 represents the given inequality. Option C is correct.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here.
A number x in no less than -8,
Implies that the number x must be equal to -8 or more,
Applying the greater equal to sign(≥) between the x and -8

x ≥ -8

Thus, x ≥ -8 represents the given inequality. Option C is correct.

Complete question:

A book shop sold fiction books and cartoon books at a ratio of 3:5. Then, it sold four times as many fiction books and 40% more cartoon books. As a result, it sold 800 more fiction books than cartoon books. How many fiction and cartoon books were sold altogether in the end?

Answer:

3040

Step-by-step explanation:

Given the following :

Sales ratio = 3:5 (fiction : cartoon)

Let total number of books sold = x

Fiction books = 3x

Cartoon books = 5x

Four times as many fiction books = 4 × fiction books = 4*(3x) = 12x - - - (1)

40% more cartoon books = 40/100 = 0.4

5x(1.40) = 7x - - - (2)

As a result, 800 more fiction books than cartoon :

Fiction - cartoon = 800

12x - 7x = 800

5x = 800

x = 160

Substitute x into (1) and (2)

Fiction books : 12(160) = 1920

Cartoon books : 7(160) = 1120

1920 + 1120 = 3,040
