Volume ratio = 1331/729 which is the cube of the linear scale factor.
To find the linear scale factor, let find the cubic root of the numerator & the denominator:
∛1331 = ∛11³ = 11
& ∛729 = ∛9³ = 9
So the linear scale is 11/9 ==> then the ratio of their surface area will be:
11²/9² ==> 121/81.
Note, if you have a linear scale, then the surface will be the square othis scale & the volume will be the cube of the linear scale
Answer:
, solution is $14.29
Step-by-step explanation:
We can create an equation for this scenario to try and solve it.
Assuming the cost of the CD is x, it’s sale tax will be 0.05x (as that is 5% of x, 0.05.)
We can write the equation in two ways:
or 
.
Assuming we take the second one (easier to work with), we can divide both sides by 1.05. The equation simplifies to x = 14.289... which rounds to x = 14.29.
Therefore, the equation is and the solution is $14.29.

Step-by-step explanation:
Rs8,100 / (Rs45 per square meter)
= 180 square meters.
The area of the 4 walls of the room is 180 sq.m.
Answer:
acute angle
Step-by-step explanation:
<h2><em><u>Finding the angle </u></em></h2>
an obtuse angle is an angle which is more than 90° but less than 180°
a right angle is 90°
a straight angle is 180°
an acute angle is less than 90°
is you look at the picture and the definitions you can notice that the angle is less than 90 ° hence its an <u>acute angle </u>
1. You would do 45 × 3 = 135 miles
2. 630 ÷ 2 = 315. 630 + 315 = 945 miles
3. 54 × 11 = 594 miles
1. Time is distance ÷ speed, so 4760 ÷ 560 = 8 1/2hours
2. 27 ÷ 54 = 0.5 hours, or 30 minutes
3. 1748 ÷ 437 = 4 hours
I hope this helps!
