Answer:
<E=<G=115°
since opposite angle of rhombus is equal
Its c (9) because the opposite of -9 is 9
V(s) = volume of cube for some side length s units
If s = 2, then we can replace s with 2 to go from v(s) to v(2)
So v(2) represents the volume of a cube when it has a side length of 2 units
Saying v(2) = 8 is the same as saying "if the side length is 2 units, then the volume of the cube is 8 cubic units"
Answer:B
Step-by-step explanation:
To find c, you must isolate it.
To do this, you must divide both sides by 5/7, since that is being multiplied by c and you must do the inverse to it to cancel it out in order to leave c by itself.
5/7c ÷ 5/7 = c
13/14 ÷ 5/7
To divide fractions, follow these steps:
Step 1- Turn the second fraction, 5/7 in this case, into its reciprocal. This means swapping the places of the numerator and denominator.
5/7 reciprocal = 7/5
Step 2- multiply the original first fraction and reciprocal second fraction.
13/14 • 7/5
13 • 7 = 91
14 • 5 = 70
13/14 ÷ 5/7 = 91/70
Step 3- Simplify if possible.
91/70
Since 70 can go into 90, you can turn this into a mixed number.
1 and 21/70
Now simplify 21/70.
Both can be divided by 7.
21 ÷ 7 = 3
70 ÷ 7 = 10
So simplified, 91/70 equals 1 and 3/10.
As a decimal, this is 1.3.
So the answer is c = 1.3, or 1 and 3/10.
Hope this helps :)
