Answer:
(8/4)100 = 200
Step-by-step explanation:
Simplify the following:
8/4×100
Hint: | Express 8/4×100 as a single fraction.
8/4×100 = (8×100)/4:
(8×100)/4
Hint: | In (8×100)/4, divide 100 in the numerator by 4 in the denominator.
4 | | 2 | 5
| 1 | 0 | 0
- | | 8 |
| | 2 | 0
| - | 2 | 0
| | | 0:
8×25
Hint: | Multiply 8 and 25 together.
8×25 = 200:
Answer: 200
Answer:
848.23
Step-by-step explanation:
Step 1: Find Volume Of The The Cake
Volume = 
Evaluate: ~848.23
Step 2: Find The Part The Was Eaten:
Full Circle: 360
Eaten = 25
Part: 25/360 = 14.4
Set 3: Find Volume Eaten:
14.4/848.23 = 58.90
Answer:
10 inches
Step-by-step explanation:
The formula for the triangle area is the following:
A = b * h / 2
Where b is the length of the base side and h is the height.
So, as the height is 4 less than the base, we have that:
h = b - 4
Using this value in the area equation, we have that:
A = b * (b - 4) / 2
30 = (b^2 - 4b) / 2
b^2 - 4b = 60
b^2 - 4b - 60 = 0
Using Bhaskara's formula to solve the quadratic equation, we have:
Delta = 4^2 + 4*60 = 256
sqrt(Delta) = 16
b1 = (4 + 16)/2 = 10
b2 = (4 - 16)/2 = -6 (negative value does not fit for this problem)
So the length of the base is 10 inches.
