What is the surface area of the cylinder with a raidus of 4 and a high of 10 square meters? Use 3.14 for pi.
Answers
Answer:
351.68 m²
Step-by-step explanation:
surface area of cylinder = 2πrh + 2πr²
r = 4m
h = 10m
2πrh + 2πr² = 2*π*4m*10m + 2*π*(4m)² = 2*3.14*4m*10m + 2*3.14*4m*4m = 351.68 m²

The mean age of 11 women in an office is 19 years old. The mean age of 11 men in an office is 26 years old. What is the mean age (nearest year) of all the people in the office?
Answers
Answer:
22.5
Step-by-step explanation:
The mean is calculated by taking the sum of the values and dividing by the count.
For instance, for the 11 women, with the mean being 19, we can see that the ages summed to 209:
11 x 19 = 209
And then we can do the same for men:
11 x 26 = 286
And now we can combine the sum and count of the men and women to find the mean for the office:
286 + 209 = 495
495/22 = 22.5
a town is 61km north of 23km east of town B.bCalculate the bearing of A from B
Answers
Answer:
20.7°
Step-by-step explanation:
Bearing angle is measured clockwise from north. The geometry can be modeled by a right triangle with the sides equal to the distances north and east of town B. The tangent relation can be used to find the angle.
__
The attachment shows the geometry. The relevant angle relation is ...
Tan = Opposite/Adjacent
tanIβ) = 23/61 . . . . . where β is the bearing angle
The angle value can be found using the arctangent function.
β = arctan(23/61) ≈ 20.659°
The bearing of A from B is about 20.7°.

the length of a rectangle plus its width is 35 cm the area 306 what are the length and width of the rectangle
Answers
Step-by-step explanation:
Let width be w, length be l
l + w = 35, so w = 35 - l
lw = 306
l(35-l) = 306
35l - l^2 = 306
l^2 - 35l + 306 = 0
(l - 17)(l - 18) = 0
l = 17 or 18
When length = 17, width = 35-17 = 18
When length = 18, width = 35-18 = 17

Answer:
48 : 1 or 48 to 1
Step-by-step explanation:
to find out the answer we have to first find out what 8 feet is in inches as shown below
8 * 12 = 96
then we apply the inch value to a scale factor setup where 96 is the larger set and 2 is the smaller image
96 : 2
find the least common denominator...
96 / 2 : 2 / 2
= 48 : = 1
and then rewrite the answer
48 : 1

Howie wants to get a car loan with 4% simple interest rate. If the car
costs $25,000, how much would Howie need to pay back at the end of
one year, including the interest?
Answers
Answer: $26,000
Explanation:
i = simple interest
P = 25,000 = amount loaned
r = interest rate in decimal form = 0.04
t = number of years = 1
So,
i = P*r*t
i = 25000*0.04*1
i = 1000
Howie needs to pay $1,000 in interest on top of the $25,000 loaned to him. In total, he needs to pay back 1,000+25,000 = 26,000 dollars.
A book has 180 pages. Haley read 12 pages each day.after a certain number of days there are 60 pages left,which equation and solve for X gives the number of days he read
Answers
Answer: She read for 10 Days, equation below
Step-by-step explanation:
Number of pages = 180
Rate = 12pages Per day
Number of days read = (180-60) /12
Days read = (total no of page - page left)/page read per day
= 120/ 12 = 10 days
Days remaining = pages left /page per day
=60/ 12 = 5

Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. What is the probability that all of Erica's flights will be on time? А 36% B 66% С 76% D 86%.
Answers
Since the chance of a flight being on time is 90%. The probability that all of Erica's flights will be on time is B 66%.
To answer the question, we need to know what probability is
What is probability?This is the likelihood for an event to occur. It is given by
P(event) = number of required outcomes/total number of outcomes
Now, given that Erica's travel plans include 4 independent flights. The chance of a flight being on time is 90%. So, P(flight) = 90%. Since they are indepent, we multiply their probability.
Probability that all of Erica's flights will be on time
So, the probability that all of Erica's flights will be on time is P(on time) = P(flight) × P(flight) × P(flight) × P(flight)
= [P(flight)]⁴
= (90%)⁴
= (0.9)⁴
= 0.656
≅ 0.66
= 66%
So, the probability that all of Erica's flights will be on time is B 66%.
