Please help!! Thank you!
Answer:
A. $209.53
Step-by-step explanation:
First, we have to take away 15% from the 850 dollar total so we can divide the remaining amount between the friends.
15% can also be written as the fraction 0.15
850 x 0.15 = 127.5
Now, we subtract the money they put away from the total amount.
850 - 127.5 = 722.5
So, the three friends have $722.50 to split between each other.
To figure out what amount everyone gets, we will first at together the total hours they worked.
17.25 + 18.25 + 14.5 = 50
Since the total hours is 50, we can divide the number of hours Shawn worked by 50 to find out what fraction of the total time he worked.
14 ÷ 50 = 0.29
0.29 is the same as the percentage 29%. This means Shawn worked for 29% of the total time out of his friends.
So, he gets 29% of the 722.50 dollars.
0.29 x 722.5 = 209.525
Round it up to 209.53
Shawn gets $209.53

When x is equal to 40, y is equal to 20
When y is 50, what is x?
Pleas help, I’ll mark as brainliest.
Answer:
When f(x) is 0, then x is -1.8.
Step-by-step explanation:
To find this, you simply have to look for the place where the line crosses the x axis. This is where y (or f(x)) is equal to 0. Since this graph only crosses that axis at x = -1.8, that is the number we are looking for.

-10+4(2b+2)=
Answer:
2(4b-1)
Step-by-step explanation:
1. You would have to distribute first. So basically you just multiply 4 · 2b which gives you 8b and then 4 · 2
Answer to first step: -10+8b+8
2. Add the numbers. It should be -10 + 8 which would give you -2
Answer to second step: -2 + 8b
3. Rearranging the terms. So, instead of doing -2 + 8b you would have to do 8b - 2
Answer to third step: 8b - 2
4. 2(4b - 1) Find what times what gives you 8 (not 1 times 8) and the same for -2

Convert the mixed number 1 2/3
to an improper fraction.
Answer:
5/3
Step-by-step explanation:
An improper fraction is a fraction, not in mixed form, where the numerator (top half) is greater than the denominator (bottom half). Since this fraction is 1 2/3, we already have 1 full and 2/3 full. So, since the 1 is full, it means that in fraction form it equals 3/3.
We can finally add the fractions. [tex]2/3+3/3=5/3[/tex].

I TAKE BACK WHAT I SAID I READ THE QUESTION WRONG MY BAD
Step-by-step explanation:
A local weather enthusiast wants to see if the last five summers have been warmer than normal for Eloy, Arizona. From the National Oceanic and Atmospheric Administration (NOAA), he knows the 30-year average for July was 90° with a standard deviation of 2. 1°. The last five summers recorded have an average of 93. 5°. If he uses a = 5%, which of the following would be valid based on the data he has gathered? He can conclude that the summers have been warmer than the 30-year average. He can conclude that the summers will continue to be warmer for the next 10 years. He does not have enough information to make a decision. The average for the last five years fits with the 30-year average.
For local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average.
What is the standard deviation data?The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
The 30-year average for July was 90°. The standard deviation for this average is 2.1°. Thus, the temperature is lie between the [tex]\pm 2.1[/tex] ranges around the 90° in the month of July.
Therefore, the range of the temperature is,
[tex]t=90-2.1=87.9^o\\t=90+2.1=92.1^o[/tex]
The last five summers recorded have an average of 93. 5° and the value of a is 5%. Thus, the reduction is,
[tex]t=92-92\times\dfrac{2.5}{100}\\t=89.70^o[/tex]
This value of temperature lies between the range of 87.9-92.1 degrees Celsius. Hence, the two average are probably the same.
Hence, for local weather of Eloy, Arizona, the average for the last five years fits with the 30-year average. Option D is correct.

The circle at the right represents a planet. The radius of the planet is about 4700 km. Find the distance d to the horizon that a person can see
on a clear day from the following height h above the planet
h=2 km
A person can see a distance of approximately km on a clear day from a height of 2 km above the given planet.
Answer:
137.13km
Step-by-step explanation:
A right triangle is formed, where h + r = 2+ 4700= 4702 km is the hypotenuse, r = 4700km is one leg and d is the other leg. By Pythagorean theorem:
4702² = 4700² + d²
d² = 4702² - 4700²
d = √18,804
d = 137.13 km

The volume of a cone is 540pi
Work out the height,of the cone.
The radius is 9cm
Formula for volume of a cone = pi x r^2 x h/3
540pi = pi x 9^2 x h/3
Divide both sides by pi:
540= 9^2 x h/3
Simplify:
540 = 81 x h/3
Divide both sides by 81:
6 2/3 = h/3
Multiply both sides by 3
H = 20
the height is 20 cm

1/5=2/10=5/25
To get 2/10, since, in the denominators, to go from 5 to 10, you multiply 5 by 2, I multiplied 1 and 2 to get the answer.
For 5/25, to go from 1 to 5 you multiply 1 by 5, so you multiply 5 by 5, and that's 25, so the denominator for that fraction is 25.

This shape is made of three identical semicircles.
The perimeter of the shape is 36 centimetres.
Another shape is made up using the same semicircles as above.
Answer:
48cm
Step-by-step explanation:
The perimeter of first shape is 36cm. There are 3 semi circle (curves).
Therefore,
3 curves of semicircle (arc length) = 36
1 curve of semicircle (arc length) = 36/3
= 12cm
In picture 2,
4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)
So,
4×12 = 48cm
