Answer:
4a:3=8:2
so we multiply 4a to 2 equal to 8 times 3
4a×2=8×3
so a=3
Answer:
a = 3
Step-by-step explanation:
Express the ratios in fractional form , that is
[tex]\frac{4a}{3}[/tex] = [tex]\frac{8}{2}[/tex] ( cross- multiply )
8a = 24 ( divide both sides by 8 )
a = 3

Jason just got tired for a new job and will make $80,000 in his first year. Jason was
told that he can expect to get raises of $5,000 every year going forward. How much
money in salary would Jason make in his 23rd year working at this job?
Answer:
$110,080
Step-by-step explanation:
This is an arithmetic sequence because each new term is obtained by adding $5000 to the preivous term.
The general formula for such an arithmetic series is
a(n) = $80,000 + ($5,000)(n - 1)
and so in his 23rd year Jason would make
a(23) = $80,000 + ($5,000)(23 - 1), or
$110,080
Answer:
$110,080 is the answer

1. 2x^2yz-32x^2y^3z
Answer:
2x²yz(1 - 4y)(1 + 4y)
Step-by-step explanation:
Given
2x²yz - 32x²y³z ← factor out 2x²yz from each term
= 2x²yz(1 - 16y²) ← difference of squares
= 2x²yz(1 - 4y)(1 + 4y)
If 25 percent of your classmates have cats, and your class has 20 students, how many students have cats? (I have to show my work)
Answer:
5 students.
Step-by-step explanation:
25% is a quarter of the amount, or 1/4. A quarter of 20 is 5, since 4 times 5 is 20. So 5 students have cats.

I want to build a shed that is 16‘ x 20‘ while I am measuring the foundation I measure the diagonal from one born to another measurement is 29 feet is the corner 90°?
Answer:
the corner is not 90 degrees
Step-by-step explanation:
To confirm if the corner is 90 degrees, we would use Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
16² + 20² =
256 + 400 =656
find the square root of 656
= 25.6 feet
If the corner was 90 degrees the diagonal should be 25.6 feet and not 29 feet

Write an equation of the line that passes through the points (-3, 3) and (0, -1)
Answer:
y = -4/3x - 1Step-by-step explanation:
Find the slope:
m = (-1 - 3)/(0 - (-3)) = -4/3The y-intercept is given:
b = -1The line is:
y = -4/3x - 1Slope
m=(-1-3)/3m=-4/3Equation in point slope form
y-3=-4/3(x+3)
y-3=-4/3x-4y=-4/3x-1Hiii, I would love it if you can help me with these! I tried my best but it's really hard and I don't understand this.

find z. explain please
Answer:
13
Step-by-step explanation:
You need to use pythagorean theorem (a^2 + b^2 = c^2). In this case 5 is a, 12 is b, and z is c. 5^2 + 12^2 = z^2, this ends up as 169 = z^2. Now you find the square root of 169 which is 13.
Step-by-step explanation:
Maybe it is root 5²time 12²=60

Samantha is trying to complete the Free Throw wellness challenge. In order to earn her chip, she needs to hit 16 out of 20 free throws on the basketball court. Her last three attempts were 12 out of 20, 13 out of 20, and 15 out of 20. How far is her average free throw percentage from the needed free throw percentage to earn the chip? (round to the nearest whole number)
Answer:
83%
Step-by-step explanation:
12 + 13 + 15 = 40
16 x 4 = 64
16 x 3 = 48
40/48 = 0.833333333333

Mrs. Long keeps a garden in her backyard. The garden is in the shape of a rectangle. The garden is 27 feet wide. If the perimeter of the garden is 200 feet, what is the length of Mrs. Long’s garden
Answer:
so Area = length x width
Area = 450, width = 9
450 = 9 x length
divide 450 by 9, and you have the length.
Perimeter = length + length+ 9 + 9
and you got your perimeter!
Step-by-step explanation:
The manager of a warehouse would like to know how many errors are made when a product's serial number is read by a bar-code reader. Six samples are collected of the number of scanning errors: 36, 14, 21, 39, 11, and 2 errors, per 1,000 scans each.
Just to be sure, the manager has six more samples taken:
33, 45, 34, 17, 1, and 29 errors, per 1,000 scans each
How reasonable is it to expect that the small sample represents larger samples?
Answer:1A. 20.5
2A. 14.54
1B. 14.625
2B. quite good reasonable
Step-by-step explanation:
Mean is used to measure central tendency (i.e. representative of data) and standard deviation is use to measure dispersion of data. The formula use to calculate mean and variance is :
1A. Mean of six sample =
⇒
⇒ Mean = 20.5
Standard deviation of six sample =
⇒ σ = 14.54
2A. Total number of error = 36 + 14 + 21 + 39 + 11 + 2 = 123
Total number of error made by all scans is 123 error per 6000 scans.
1B. Mean of all 12 samples is:
⇒
⇒ Mean = 23.5
Standard deviation of all 12 samples =
⇒ σ = 14.625
2B. Taking small sample instead of large sample can be quite risky sometimes as larger sample give us more accurate result than small sample.
But here we can take a small sample because the mean of both the size of the sample is near about.

Give coordinates for any three points that are on the same vertical line. Include at least one point that has a mixed number as a coordinate. (Can the numbers be made up? I put in (1 1/2,4), (2,4), (5,4) as the answer. Is that correct?)
Answer: No
Step-by-step explanation:
Points inserted are
[tex](1\ \frac{1}{2},4), (2,4), (5,4)\\[/tex]
As all the points have the same y-coordinate, therefore, they must lie on the same horizontal line of [tex]y=4[/tex]
So, the ingested points are not correct.
Points maybe [tex](1,2), (1, 3), (1,3\ \frac{1}{2})[/tex] as they line on the same vertical line.
