Answer:
16 and 22.5
Step-by-step explanation:
To find the mean, simply add all the numbers together and divide by the amount of values that are present in the data set.
1.) (20 + 15 + 19 + 16 + 10)/5 = 16
2.) (19 + 23 + 11 + 30 + 27 + 27 + 22 + 26 + 16 + 24)/10 = 22.5

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations)
Answer:
18π[tex]cm^{2}[/tex]
Step-by-step explanation:
Firstly we will have to find the area of the whole circle so we do....
[tex]A_{circle} =[/tex] π[tex]r^{2}[/tex]
[tex]A_{circle} =[/tex] [tex]9^{2}[/tex]π
[tex]A_{circle} =[/tex] 81π[tex]cm^{2}[/tex]
If we are talking about a whole circle the angels in the middle will be equal to 360°. But in our case we are only talking about 80° out of 360°. In other words we have to find out the area what [tex]\frac{80}{360}[/tex] (in other words [tex]\frac{2}{9}[/tex] )from the whole area is equal to. So we do....
81π[tex]cm^{2}[/tex] x [tex]\frac{2}{9}[/tex] = 18π[tex]cm^{2}[/tex]

I borrow a mortgage of £185,000 over 30 years at an interest rate of 4.1%. How much will I pay back overall?
Answer:
617,580.56
Step-by-step explanation:
I'm going to assume that there will be only 1 payment made at the end of the loan and the interest is compounding anually.
Using the compound interest formula we have
185000(1+.041)^30
Compute this and get
617580.56
George wants to rent a car for a road trip with his friends. He checked the rentals with 2 companies. Compony A charges a non refundable fee of 50$ and then also $150 for each day. Compony B using the function 50(2x+1). Compare the two functions. Which function has a great rate of change?
Answer: The function of company A.
Step-by-step explanation:
For a linear equation:
y = a*x + b
the rate of change is "a", the coefficient that is multiplicating the variable.
Now, for company A we know that:
There is a fixed fee of $50, and $150 for each day.
So if you rent the car for x days, the total cost will be:
y = $150*x + $50
Then for this company, the rate of change is $150.
For company B we have the function:
y = $50*(2x + 1)
Where again, x is the number of days that you rent the car.
We can rewrite this as:
y = $50*2*x + $50*1
y = $100*X + $50
In this case, the rate of change is $100
Then the company with a great rate of change is the function for company A.
Using the property of exponents, what do you need to multiply 10^2 by to get 10^4 ?
Answer:
We conclude that using the property of exponents, we need to multiply 10² to get 10⁴.
Step-by-step explanation:
Let 'x' be the number we need to multiply 10² by to get 10⁴.
So the expression becomes
[tex]10^2\:\times\:x\:=\:10^4[/tex]
Divide both sides by 10²
[tex]\frac{10^2x}{10^2}=\frac{10^4}{10^2}[/tex]
[tex]\:x=\frac{10^4}{10^2}[/tex]
Apply the exponent rule:
[tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
so the expression becomes
[tex]x=\frac{10^4}{10^2}=10^{4-2}[/tex]
[tex]x=10^2[/tex]
Therefore, we conclude that using the property of exponents, we need to multiply 10² to get 10⁴.
The cost of 9 donuts is $5.50. how many donuts can you buy for $33.00
9514 1404 393
Answer:
54
Step-by-step explanation:
Let d represent the number of donuts. The cost is proportional to the number, so we have ...
d/33.00 = 9/5.50
d = 33.00(9/5.5) = 9·6 = 54
You can buy 54 donuts for $33.00.
When a bush was first planted in a garden, it was 20 cm tall. After two months, it was 300% as tall as when it was first planted. Use mental math to find how tall the bush was after the two months.
Answer:
Length of the bush after 2 months = 60 cm
Step-by-step explanation:
When the bush was planted in the garden, height of the bush = 20 cm
200% as tall as initial length = 2 times of the initial length
300% as tall as initial length = 3 times of the initial length
Therefore, after 2 months, length of the bush = 20 × 3
= 60 cm
After 2 months, length of the bush is 60 cm.
convert 17 kilometers to the nearest whole mile
Answer:
11miles

On a map, 1 inch equals 20 miles. Two cities are 7 inches apart on the map. What is the actual distance between the cities?
Answer:
140 miles
Step-by-step explanation:
1 times 20 (1 inch=20 miles)
2 times 20 (2 inches=40 miles)
3 times 20 (3 inches=60 miles)
4 times 20 (4 inches=80 miles)
5 times 20 (5 inches=100 miles)
6 times 20 (6 inches=120 miles)
7 times 20 (7 inches=140 miles)

15 bakers complete a big order in 24 hours. How many hours would it take 18 bakers to complete the same order? Please help with explanation, thank you!
Answer:
it will take 20 hours for 18 bakers to complete the same order
Step-by-step explanation:
15 bakers take 24 hours
18 bakers take x hours
15 * 24 = 360 "baking hours"
18 * x = 18x " baking hours"
360 baking hours = 18x baking hours
360 = 18x
18 18
20 = x
x = 20 hours

Answer:
1) 6 (9x - 5)
2) 4 (1 + 6)
Step-by-step explanation:
1.
54x - 30
The greatest common factor is 6, hence take out 6
6 (9x - 5)
2.
4 + 24
The greatest common factor is 4, take out 4
4 (1 + 6)

Estimate the quotient by rounding the expression to relate to a one-digit fact 1275 ÷ 588 A.2 B.3 C.4 D.5
Answer:
2
Step-by-step explanation:
Round the divisor to the nearest 10 or 100, depending on how many digits are in the divisor.
Round the dividend to the nearest 10, 100, or 1,000 so that all of the digits, except the first one are zeros.
Divide 600 by 30.
Compare your estimate to the exact answer to determine if the exact answer is reasonable.
Hi. I need help with this question (see image). Please show workings.
Answer:
[tex]\frac{dy}{dx}[/tex] = 8(2x + 3)³
Step-by-step explanation:
Differentiate using the chain rule
Given
y = f(g(x)) , then
[tex]\frac{dy}{dx}[/tex] = f'(g(x)) × g'(x)
Here
f(x) = [tex](2x+3)^{4}[/tex] ⇒ f'(x) = 4(2x + 3)³
g(x) = 2x + 3 ⇒ g'(x) = 2
Thus
[tex]\frac{dy}{dx}[/tex] = 4(2x + 3)³ × 2
= 8(2x + 3)³

Answer:
angle XYW = -20x + 155
Step-by-step explanation:
angle XYZ = 150
angle WYZ = 20x - 5
angle XYW = y
angle XYZ = 20x - 5 + y
150 = 20x - 5 + y
150 + 5 = 20x + y
y = -20x + 155
So angle XYW = -20x + 155

I need help with Geometry
Answer:
B
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is
difference of 2 sides < x < sum of 2 sides , that is
17 - 10 < x < 17 + 10
7 < x < 27
In terms of AC , then
7 < AC < 27 → B
Answer:
all u need to know is that a side of a triangle is always smaller ( not smaller or equall) than the sum of two other sides of the triangle which in this case means AC is smaller than 27 and the only choice that is meantioning this is B so yea thats it (u cab always eleminate options if u dont know eveythibg about question but u just know some of them are wrong for some reason)
