A car averages 27 miles per gallon. If gas costs $4.04 per gallon, which of the following is closest to how much the gas would cost for this car to travel 2,727 typical miles?a. $44.44

b. $109.08

c. $118.80

d. $408.04

e. $444.40

Answers

(D) 408.04 is the correct answer. If you divide 2,727 miles by 27 miles per gallon you will get the number of gallons: = 101. Then, multiply the number of gallons by the cost per gallon: 101(4.04) = 408.04. This gives the cost of gas for this car to travel 2,727 typical miles. Hope this helps!

d. $ 408.04 is the answer

What do i do if i have a problem like this x exponent 5 = 1024 and (-1/7) exponent -x = -1/343

Answers

x^5 = 1024 = 4^5
Therefore, x = 4.

Given, (-1/7)^-x = -1/343
(1/7)^-x = 1/343
(1/7)^-x = (1/7)^3
-x = 3
x = -3

mr.chan made 252 cookies for the annual fifth grade class bake sale . they sold 3/4 of them and 3/9 of the remaining cookies were given to P.T.A members . mr.chan allowed the 12 student helper to divide the cookies that are left equally how many cookies will each student get. please help !!!! hurry i need help helppppppppppppppppppppppppppppppppppppppppppp

Answers

Answer

Find out the how many cookies will each student get.

To prove

As given

mr.chan made 252 cookies for the annual fifth grade class bake sale .

they sold $(3)/(4)$ of them

Than

$Number\ of\ cookies\ left = (3* 252)/(4)$

= 189

Number of cookies left after sold = 252 - 189

= 63

$(3)/(9)$ of the remaining cookies were given to P.T.A members .

Than

$Number\ of\ cookies\ left\ when\ given\ to\ P.T.A\ members = (3* 63)/(9)$

= 21

Number of cookies left after giving to P.T.A members = 63 - 21

= 42

As given

mr.chan allowed the 12 student helper to divide the cookies that are left equally.

$Each\ student\ get\ cookies =(42)/(12)$

= 3.5

Therefore the 3.5 cookies each student gets.

3¹/₂ or 3.5 cookies

Further explanation

Given:

Mr. Chan made 252 cookies for the Annual Fifth Grade Class bake sale.
They sold $(3)/(4)$ of them and $(3)/(9)$ of the remaining cookies were given to P.T.A members.
Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.

Question:

How many cookies will each student get?

The Process:

Step-1

$Let \ us \ prepare \boxed{252 / 4 = 63}$

Then, let us create a suitable diagram as follows:

$\boxed{63}\boxed{63}\boxed{63}\boxed{63} = 252 \ cookies}$

So, 1 unit of diagram is equal to 63 cookies.

Mr. Chan sold $(3)/(4)$ of them, that is $\boxed{ \ 3 \ units * 63 \ cookies = 189 \ cookies \ sold \ }$
The remaining cookies are $\boxed{ \ 252 - 189 = 63 \ cookies \ }$ , or 1 unit left of the diagram above.

Step-2

$Let \ us \ prepare \boxed{63 / 9 = 7}$

Then, let us create a suitable diagram as follows:

$\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7}\boxed{7} = 63 \ cookies}$

So, 1 unit of diagram is equal to 7 cookies.

Next, $(3)/(9)$ of the remaining cookies were given to P.T.A. members, that is $\boxed{ \ 3 \ units * 7 \ cookies = 21 \ cookies \ }$ .
The last number of cookies remaining was $\boxed{ \ 6 \ units * 7 \ cookies = 42 \ cookies \ }$ or $\boxed{ \ 63 - 21 = 42 \ cookies \ }$ .

Step-3

Mr. Chan allowed the 12 student helper to divide the cookies that are left equally.

Let us calculate how many cookies will each student get.

$\boxed{ \ 42 \ cookies / 12 \ students \ }$

$\boxed{ \ = (42)/(12) \ }$

The numerator and denominator are equally divided by 6.

$\boxed{ \ = (42 / 6)/(12 / 6) \ }$

$\boxed{ \ = (7)/(2) \ }$

$\boxed{ \ = (6)/(2) + (1)/(2) \ }$

$\boxed{\boxed{ \ = 3(1)/(2) \ }}$

Thus, each student will get $3(1)/(2)$ cookies.
