Answer:
1
Step-by-step explanation:
The surface area of a cone with circumference base of 24π inches and slant height of 20 inches is 384π inches² in terms of π.
<h3>Surface area of a cone</h3>
surface area = πr(r + l)
where
- r = radius
- l = slant height
Therefore,
l = 20 inches
24π = 2πr
r = 12
Therefore,
surface area = π(12)(12 + 20)
surface area = 12π(12 + 20)
surface area = 12π × 32
surface area = 384π inches²

Answer:
x = 3
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
= 13 ( multiply both sides by 2 to clear the fraction )
7x + 5 = 26 ( subtract 5 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
Answer:
Equation: 5c + 7 = 2
Solution: The number is -1.
Step-by-step explanation:
The unknown number is c.
"the product of a number and 5" is 5c
"Seven more than the product of a number and 5" is 5c + 7
"Seven more than the product of a number and 5 equals 2" is 5c + 7 = 2
The equation is
5c + 7 = 2
To solve, we first subtract 5 from both sides.
5c + 7 - 7 = 2 - 7
5c = -5
Now divide both sides by 5.
5c/5 = -5/5
c = -1
Answer: The number is -1.
Answer:
1. 2/5
Step-by-step explanation:
When it says the ratio is 5 to 2, that means 5 is always first:
5 : 2 is correct
5/2 is correct
10 : 4 is correct (multiplied 2 on both sides)
2/5 is incorrect because 2 is first. That means that this ratio would be 2 to 5, not 5 to 2.
