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

Answer:
7.9 m
Step-by-step explanation:
Use the Pythagorean theorem: a²+b²=c²
This formula can be used to solve a side of any right (90°) triangle.
c² is the length of the hypotenuse (the diagonal side of the triangle, opposite to the 90° angle)
So, c = 32m.
Sides a and b are the legs of the triangle, but we only know one side. Plug numbers into the formula:
31² + b² = 32²
961 + b² = 1024 Subtract 961 from both sides to get b² by itself.
b² = 63
√b² = √63 Square root both sides to get b by itself.
b = 7.93725
Answer is 7.9 meters, rounded to tenths place

Sharon made $45 in interest by placing $500 in a savings account with simple interest for 1 year. What was the interest rate?
Answer: The interest rate was 9%.
Step-by-step explanation:
If principal amount P is invested at the rate of r percent with simple interest(I) for t years, the formula to find rate :
[tex]R=\dfrac{I\times100}{P\times t}[/tex]
As per given,
P = $ 500, I = $45, t = 1 year
Substitute values in formula , we get
[tex]R=\dfrac{45\times100}{500\times1}\\\\\Rightarrow R=9\%[/tex]
Hence, The interest rate was 9%.
A car travels a distance of 190 miles in a time of 3.4 hours.
What is its average speed rounded to 1dp?
Answer:
55.9 mph
Step-by-step explanation:
190/3.4 = 55.88 mph rounded to one dp = 55.9 mph
A car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then its average speed will be [tex]56[/tex] miles per hour.
What is average speed ?Average speed is speed is the total distance traveled by the car in a particular time of interval.
Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]
We have,
Distance [tex]=190[/tex] miles
Time[tex]= 3.4[/tex] hours
So, Using the above given formula,
Average speed [tex]=\frac{Total \ Distance}{Total \ Time}[/tex]
[tex]=\frac{190}{3.4}[/tex]
[tex]=56[/tex] miles per hour
So, the average speed of car is [tex]56[/tex] miles per hour which is find out using the above given formula.
Hence, we can say that if a car travels a distance of [tex]190[/tex] miles in a time of [tex]3.4[/tex] hours, then its average speed will be [tex]56[/tex] miles per hour.

Suppose a city with population 600,000 has been growing at a rate of 4% per year. If this rate continues, find the population of this city in 25 years.
Answer:
15,600,000
Step-by-step explanation:
We start with our initial population of 600,000. Then multiply that with the rate of 4% (0.04 in decimal, or 1.04 so that the 0.04 is automatically added to the 600,000.)
600,000 · 1.04y = projected populationy = 25600,000 · 1.04(25) = projected populationsimplify!15,600,000 = proejcted populationif triangle def is similar to triangle jkl find kl

What is the inverse function (equation) of f(x) = 6x - 5 ?
Step-by-step explanation:
Given
f(x) = 6x - 5
f^-1(x) = ?
Let
y = f(x)
y = 6x - 5
Interchanging the roles of x and y we get
x = 6y - 5
6y = x + 5
y = ( x + 5 ) / 6
So therefore f^- 1(x) = (x + 5) / 6

Suzanne, Latisha, and Morgan measure their heights. Suzanna is 0.8 times the height of Latisha, and Morgan is 1.09 times the height of Latisha. Who is the tallest? Who is the shortest?
Answer:
Tallest = Morgan
Shortest = Suzanna
Step-by-step explanation:
Assuming Latisha = 1
0.8 is less than 1, meaning it's 80% the height of Latisha, so this means Suzanna is shorter than Latisha.
1.09 is more than 1, Morgan is taller than Latisha.
Morgan is tallest and Suzanna is shortest, Latisha in the middle.
