Answer:

More than 250 miles

Step-by-step explanation:

Rental cost of company A is $80 + $0.6 per mile driven and company B also has a rental cost of $30 + $0.8 per mile driven.

To find the moment when company A rental cost matches that of company B,we have to create an equation that is ideal for both parties.

80 +0.6x = 30 + 0.8x

Where x is the number of miles traveled by both trucks.

Simplifying the above equation, we have

0.2x = 50 divide both sides by 0.2

= 250 miles is when both rental cost matches .

Therefore, the number of miles needed to be driven so as the rental cost of company A to better company B should be more than 250 miles

Answer:

f(x + 2) = 3x + 2

Step-by-step explanation:

Simply replace wherever you find x in the function f(x) with (x + 2), like so:

f(x + 2) = 3(x + 2) - 4

f(x + 2) = 3x + 6 - 4

f(x + 2) = 3x + 2

Three friends each have some ribbon. Carol has 90 inches of ribbon, Tino has 7.5 feet of ribbon, and Baxter has 3.5 yards of rib
erastovalidia [21]

Answer: 306 inches or 25.5 feet or 8.5 yards.

Step-by-step explanation:

Given: Carol has 90 inches of ribbon, Tino has 7.5 feet of ribbon, and Baxter has 3.5 yards of ribbon.

1 feet = 12 inches

length of ribbon Tino has = 12 x 7.5 = 90 inches

1 yard = 36 inches

length of ribbon Baxter has = 3.5 x 36 = 126 inches

Total ribbon they have = (length of ribbon Carol has) + (length of ribbon Tino has) + (length of ribbon Baxter has)

= (90+90+126) inches

= 306 inches

In feet , Total ribbon = \dfrac{306}{12}\text{ feet}   [\text{ 1 inch}=\dfrac{1}{12}\text{ feet}]

=\text{25.5 feet}

In yards, Total ribbon =\dfrac{25.5}{3}\text{ yards}    [\text{1 feet}=\dfrac{1}{3}\text{ yard}]

=\text{ 8.5 yards}

Hence, the total length of ribbon the three friends have is 306 inches or 25.5 feet or 8.5 yards.

How do I solve this math problem
Angelina_Jolie [31]

Answer:

Cross Multiply.

Step-by-step explanation:

Multiply the denominator (3) of one side and the numerator (n).

Then, multiply the numerator (2) of on side and the denominator (4) of the other.

3n = 8

You divide both sides by 3 to have n be by itself, equaling ~2.6 or 8/3.

Can someone help please
yanalaym [24]

Step-by-step explanation:

a) The volume of the prism is

V = (n^2 - 1)×(n^2 - 1)×(5n)

\:\:\:\:= (n^4 - 2n^2 + 1)(5n)

\:\:\:\:=5n^5 - 10n^3 + 5n

b) If the dimensions L of the prism are tripled, the new volume will be

V' = (3L)^3 = 27L^3 = 27V

so it will increase by a factor of 27.
