Answer:
58π or about 182.12
Step-by-step explanation:
In order to find circumference with diameter, you need to use the formula:
C = πd
Multiply the diameter (58) by pi, and since pi is an irrational number, let's use 3.14.
3.14(58) = 182.12
58π would be the answer as well if you don't multiply pi.
The average mass of 5 boys is 50 kilograms. Another boy’s mass is added and the average goes to 40 kilograms. What was the mass of the sixth boy?
The mass of the sixth boy is 80 kilograms.
What was the mass of the sixth boy?It's important to note that a mean simply means the average of a set of numbers that are given. In this situation, the average mass of 5 boys is 50 kilograms. The total mass will be:
= 50 × 5
= 250 kilograms
In this case, when another boy’s mass is added and the average goes to 55 kilograms. The total mass will be:
= 55 × 6
= 330 kilograms.
The average mass of the last boy will be:
= 330 - 250
= 80 kilograms

Danny opened a savings account and deposited $100.00. The account earns 2% interest,
compounded annually. If he wants to use the money to buy a new bicycle in 3 years, how
much will he be able to spend on the bike?
nt
P(1 + 1)^²₁. where A is the balance (final amount), P is the principal
Use the formula A = P 1 +
(starting amount), r is the interest rate expressed as a decimal, n is the number of times per
year that the interest is compounded, and t is the time in years.
Round your answer to the nearest cent.
Answer: f = p * (1 + r) ^ n
f is the future value.
p is the present value.
r is the interest rate per time period.
n is the number of time periods.
time periods are months.
rate is the percent divided by 100.
p = 100
r = 6% per year / 12 = .5% per month / 100 = .005 per month.
n = 2 years * 12 = 24 months.
formula becomes f = 100 * (1 + .005) ^ 24
solve for f to get:
f = 112.7159776 = 112.72
that's how much Danny will be able to spend on the bike in 2 years.

if you have a learner's license, how many hours of driving experience are required to earn the class e license?
If you currently hold a learner's permit, you must complete 50 hours of practice driving under supervision, including at least 15 hours after dusk, before you may take a road test to get a class e license.
Explain the term learner's license?The candidate receives a learner's license after passing a written or online exam that assesses his understanding of traffic laws.
You may practice driving the public roads after receiving a learner's permit as long as you are supervised by someone who has a valid driving license.Before being permitted to receive a full driver's license, first-time drivers must first obtain a driver's permit, sometimes referred to as a learner's permit, driver's licence license, or provisional license. Prior to passing your driving test, you are able to drive (with some restrictions) if you obtain a driver's permit. Each state has a different minimum age requirement for obtaining a driver's license.Thus, if you currently hold a learner's permit, you must complete 50 hours of practice driving under supervision, including at least 15 hours after dusk, before you may take a road test to get a class e license.

Using the unit circle, on what interval is the cosine function increasing? (0, startfraction pi over 2 endfraction) (0, pi) (startfraction pi over 2 endfraction, startfraction 3 pi over 2 endfraction) (pi, 2 pi)
The interval where the cosine function is increasing is (π, 2π).
Finding the value of the cosine function in different intervals:The cosine function for the interval (0, π/2) gives
cos(x) = cos(0) = 1
cos(x) = cos(π/2) = 0
So, the value of the function is decreasing in this interval.
Then, for the interval (0, π), it gives
cos(0) = 1; cos(π) = -1
So, the value of the cosine function is decreasing in this interval.
Then, for the interval (π/2, 3π/2), it gives
cos(π/2) = 0
cos(π) = -1
cos(3π/2) = 0
So, the value of the function decreases up to x = π and then increases up to the same value as before i.e., cos(π/2) = cos(3π/2).
Then, for the interval (π, 2π), the cosine function gives
cos(π) = -1
cos(2π) = 1
Thus, the cosine function in this interval increase from -1 to 1.
Therefore, in the interval (π, 2π), the cosine function is increasing.

a. The given sequence is not an arithmetic sequence.
b. The distance a falling body covered in t = n seconds of movement is 5n²meters.
What is the distance?
Distance is a measurement of how far apart two things or points are, either numerically or occasionally qualitatively. The distance can refer to a physical length in physics or to an estimate based on other factors in common usage.
Here, we have
a. A sequence can be said arithmetic sequence if the difference between any two consecutive terms remains the same.
In this case, the difference between 20 and 5 is 15, and the difference between 45 and 20 is 25, this shows that the difference between two consecutive terms is not the same.
Hence, it can be said that the given sequence is not an arithmetic sequence.
b. To evaluate the distance covered by the body in “n” seconds, Substitute t=n in d(t) then d(n) will represent the distance covered by the body in “n” seconds
d(n)=1/2 g(n)²
d(n) = 1/2(10)(n)²
d(n) = 5n²meters
Hence, the distance a falling body covered in t = n seconds of movement is 5n²meters.

37.94
10.06
24.95
Answer:
$24.95
Step-by-step explanation:
2.99 times 4 is 11.96, and you would add that with 12.99 to get 24.95.
Answer:
Jaylen have left 23.05 $
Step-by-step explanation:
5 pounds of apples = 12.99 $
4 cupcakes = 2.99 $/apple
Total money = 48 $
All the cupcakes costs = 4*2.99 = 11.96 $
Then she bought in total:
48 -(12.99 + 11.96)

(a) Express the distance he jogged on Saturday as a percentage of the total distance jogged on both days.
(b) Find the percentage decrease in the distance he jogged from Saturday to
Sunday.
Answer:
a) 4,000 meters
b) - 56.25% (or -56% with 2 sig figs
Step-by-step explanation:
Calculate the total distance Ahmad jogged on both days. This will require a conversion unit to make the distances the same units.
Sat.: 3200 m
Sun: 1.8 km
(1,000m/km)
(1.8km)*(1,000 m/km) = 1,800 m jogged on Sunday
Total distance jogged = 3,200 m + 1,800 m = 4,000 meters total jogged
a) Percentage jogged on Saturday:
(3,200 m)/(4,000 m) = 0.80 or 80%
b) Percentage Decrease (From Saturday to Sunday):
Sat: 3200 m
Sun: 1800 m
Difference = 1400 m (decrease)
Percentage Decrease = (1800/3200) = 56.25%
Ahmad's distance on Sunday was a 56.25% decrease from Saturday.
