Curved surface of a cone of slant height 20 cm and base radius 14 cm is ____. * 1 point 280 sq.cm 2080 sq.cm 1496 sq.cm 880 sq.cm
Answer:
880 cm²
Step-by-step explanation:
Given that :
Curved surface area of a cone : πrl
r = base Radius = 14 cm
l = slant height = 20 cm
Hence,
Curved surface area = π * 14 * 20
Curvwd surface are = π * 14 * 20
Curved surface area = 879.64594 cm²
Curved surface area = 880 cm²

Connor and Angie helped take attendance during their school's practice
fire drill. Connor counted 470 in attendance and Angie counted 479. The
actual attendance was 470. What is the percent error? (ROUND TO THE
NEAREST TENTH.) *
0.019
1.2%
1.9%
12%
Answer: 1.9%
Step-by-step explanation:
The percent error formula is [tex]\frac{accepted-experimental}{accepted}[/tex] so input our values also keep in mind when we do percent error we use absolute error which means no negative percentages so 470-479/470= -9/470 or 9/470
as a decimal 9/470 is 0.019 or 1.9% so the answer is 1.9%
Nolan gives some pans of brownies to his 3 friends equally If he has 1/3 pans of brownies, how many pans of brownies will each friend receive?
Answer: 1 only have 1/3 of pans whutch mean each will get 1
Answer:
[tex]\frac{1}{9}[/tex] of the pan
Step-by-step explanation:
First, we need to divide 1/3 by 3. That way we can find how much is given to each person.
[tex]\frac{1}{3}[/tex] divided by 3
= [tex]\frac{1}{3}[/tex] * [tex]\frac{1}{3}[/tex]
= [tex]\frac{1}{9}[/tex]
Each friend will get [tex]\frac{1}{9}[/tex] of the pan.
Susan has 50% more books than Michael. Michael has 40 books. If Michael buys 8 more books, will Susan have more or less books than Michael? Use any method to solve the problem
Answer:
Susan has more books than Michael.

If Susan has 50% more books and Michael has 40 books, that means Susan has 1.5 times 40 = 60
40 + 8 = 48
60 is more than 48, so Susan has more books than Michael

If there are two children in the Patel family. They are twins of the same age. Then zero is the range of their ages
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Given,
There are two children in the Patel family.
They are twins of the same age.
Let x be the age of two children.
As they are twins so the age of children's is same.
The formula of range is highest minus lowest.
range = highest - lowest
Range=x - x
Range =0
Hence, the range of their ages is 0.

change 6 out of 100 to a percentage
Answer:
6%
Step-by-step explanation:
[tex]\frac{6}{100}[/tex]
For fractions with 100 as the denominator, it will always have the numerator as its percent value. This is because percentages are essentially comparing a number to 100, which is what [tex]\frac{6}{100}[/tex] is doing. Therefore, [tex]\frac{6}{100}[/tex] as a percentage would be 6%.
