Paul cuts apples into cubes with a height of 1 1 fraction bar 3 in. He then coats the apples in caramel. Hiw much area is covered in caramel

Answers

ok so since we don't know how many cubes are covered, I will solve for how much area was covered on 1 cube
cube has 6 faces, all squares
area of square=side^2
therefor surface area (area covered by carmael)=6 times side^2
side=1 and 1/3
convert 1 and 1/3 to imporoper
1 and 1/3=1+1/3=3/3+1/3=4/3

Surface Area=6 times side^2
SA=6(4/3)^2
SA=6(16/9)
SA=96/9
SA=10 and 6/9
SA=10 and 2/3

answer is 10 and 2/3 in^2 is covered per cube
(if you are given a number of cubes, multiply 10 and 2/3 in^2 by number of cubes)

What is 2x3xnxn=54 what is n?

Answers

It would be
2x3xnxn
N has a 1 in front of it it's just not shown
So
2x3x1nx1n then you'd at as much as possible
5x2n

$2x^3*n*n=54$

$\ Use \ Product \ Rule$ $x^ax^b=x^a^+^b$

$2x^3n^2=54$

$x^3n^2= (54)/(2)$ $\ Divide \ both \ sides \ by \ 2$

$x^3n^2=27$

$n^2= (27)/(x^3)$ $\ Divide \ both \ sides \ by \ x^3$

$n=+ \sqrt{ (27)/(x^3)}$ $\ Take \ the \ square \ root \ of \ both \ sides$

______________________________________________________

$If \ you \ mean \ 2x*3xnxn=54 . \ Lets \ Solve \ for \ n$

$2x*3xnxn=54$

$6x^3n^2=54$

$x^3n^2= (54)/(6)$ $\ Divide \ both \ sides \ by \ 6$

$x^3n^2=9$

$n^2= (9)/(x^3)$ $\ Divide \ both \ sides \ by \ x^3$

$n=+ \sqrt{ (9)/(x^3) }$ $\ Take \ the \ square \ root \ of \ both \ sides$

Carmen borrowed money from her sister. Each month she makes four payments , with an average payment of no more than $ 200 . This month she has already paid her sister $ 225 , $245 , and $ 235 What is the maximum amount she can pay for the fourth payment ?

Answers

Answer:

$95

Step-by-step explanation:

We are told that Carmen makes a monthly payment of no more than 200 dollars. We then see her going above the 200 dollars so we look to the tens and ones place. We see that we now have 25, 45, and 35 dollars. Add them up and you get 105 dollars. 200-105=95 so your awnser is $95.

What is the LCD of 6/7, 3/5, and 1/4?
A.33
B.70
C.100
D.140

Answers

The least common denominator of 6/7, 3/5, and 1/4 is D. 140

The LCD of 3/5 and 1/4 is 20. However, 6/7 must be considered.
So, 20 x 7 = 140.

140 ÷ 7 = 20
140 ÷ 5 = 28
140 ÷ 4 = 35

Least common denominator is need when we add or subtract fractions.

Answer:

D. 140
