Answer:
c=7
Step-by-step explanation:
−5c+5=4c−58
Subtract 4c from both sides.
−5c+5−4c=4c−58−4c
−9c+5=−58
Subtract 5 from both sides.
−9c+5−5=−58−5
−9c=−63
Divide both sides by -9.
-9c/-9= -63/-9
c=7
Answer:
Ypu have to multiply all the sides to find your answer
Step-by-step explanation:
A right rectangular prism can be used to simulate an aquarium. Its measurements are 14 by 7 by 4 inches. If there are 153 cubic inches of water in the aquarium, There is a 61 % empty space.
<h3>What is volume?</h3>
The term “volume” refers to the amount of three-dimensional space taken up by an item or a closed surface. It is denoted by V and its SI unit is in cubic cm.
The volume of the aquarium is;
V=14 × 7 × 4 = 392 inch³
The % by which the container is empty is found as;

Hence, there is a 61 % empty space.

Answer:
540 mm
Step-by-step explanation:
Here we are given a rectangular box with dimensions of the top surface as 40 mm and 230 mm
We are asked to determine the measurement of the ribbon which may go all the way around the edge of it. Basically we are being asked the perimeter of the top surface. The perimeter is given as the
P=2 (l+w)
l = 230
w = 40
P=2(230+40)
P=2 x 270
P= 540
Hence we need 540 mm of ribbon to go all the way around the edge of the top of the box.
Step-by-step explanation:
the area of the half-circle:
πr² /2= 3.14* 20² /2= 3.14 * 400 /2 =1256/2=628cm²
50*80/2=2000cm²
Shaded area:
2000-628=1372cm²
