RedAnswer:
(x-1-3y) x (x-1+3y)
Step-by-step explanation:
x^2-2x+1-9y^2
Using a^2 - 2ab + b^2 = (a-b)^2 (factor the expression) = (x-1)^2 - 9y^2
(x-1)^2 - 9y^2 = (x-1-3y) x (x-1+3y) should be the answer :)

At MLK Middle School, enrollment increased from 320 students in 2019 to 750 students in 2020 after the pandemic. What is the percent increase in enrollment?
Answers
Answer:
134.3%
Step-by-step explanation:
Working out a percentage increase or decrease between the two numbers is pretty simple. The resulting number (the second input) is 750 and what we need to do first is subtract the old number, 320, from it:
750 - 320 = 430
Once we've done that we need to divide the result, 430, by the original number, 320. We do this because we need to compare the difference between the new number and the original:
430/320 = 1.343
We now have our answer in decimal format. How do we get this into percentage format? Multiply 2.3 by 100? Ding ding ding! We have a winner:
1.343 x 100 = 134.3%
Consider a value to be significantly low if its z score less than or equal to -2 or consider a value to be significantly high if its z score is greater than or equal to 2.
A data set lists weights (grams) of a type of coin. Those weights have a mean of 5.37215 g and a standard deviation of .05421 g. Identify the weights that are significantly low or significantly high.
What weights are significantly low? (Round to five decimal places as needed. Use ascending order.)
What weights are significantly high?
(Round to five decimal places as needed. Use ascending order.)
Answers
Answer:
z₁ = 5,361308 this value, and values below this value, should be considered significantly low
z₂ = 5,48057 this value, and values above this value, should be considered significantly high
Step-by-step explanation:
z (score) = z₁ - μ₀ / σ
where μ₀ is mean and σ the standard deviation.
if z (score) is equal to -2 ( or less) then
-2 = (z₁ - 5,37215)/0,05421
( -2 )*0,05421 = z₁ - 5,37215
- 0,10842 = z₁ - 5,37215
z₁ = 5,37215 - 0,010842
z₁ = 5,361308
And if z = 2
2* 0,05421 = z₂ - 5,37215
0,10842 = z₂ - 5,37215
z₂ = 5,37215 + 0,10842
z₂ = 5,48057

Savings and Loan Counselor:

of interest only, and pay the full amount of the principal at the
end of the term. If the interest rate is 12% annually, what are the
monthly payments for a five-year term?
Answers
Step-by-step explanation:
A.
Cost of 4 lots for $48,000= 48000*4
=$192,000
Sales made from all 7 lots = 33000*7
= $213,000
Profit =213,000-192,000
Profit =$39,000
Percent profit =(39000/192000) *100
=0.20*100
=20%
B.
Total interest formula=
Principal Loan Amount x Interest Rate x Time
Interest =30000x0.12x5
Interest = $18,000
Monthly payments for 5 years
= 18000/12*5
=18000/60
=$300

A car breaks from a speed of 108km/h to 72km/h during a displacement of 100m, what is its aceleration ?
Answers
First, note that 100 m = 0.100 km.
Recall that
v² - u² = 2 a ∆x
where u and v are initial and final velocities; a is acceleration; and ∆x is displacement. Solve for a :
(72 km/h)² - (108 km/h)² = 2 a (0.100 km)
a = ((72 km/h)² - (108 km/h)²) / (0.200 km)
a = -32,400 km/h²
If you want to convert this to m/s², we have
(-32,400 km/h²) = (-32,400 km/h²) (1000 m/km) (1/3600 h/s)²
(-32,400 km/h²) = -2.50 m/s²

24 + 28 as a product of two factors using the GCF and distributive property
Answers
Answer:
52
Step-by-step explanation:
Using GCF:
The factors of 24 are; 1, 2, 3, 4, 6, 8, 12, 24
Factors of 28 are; 1, 2, 4, 7, 14, 28
The highest greatest common factor is 4.
Now, 4 × 6 gives 24
While 4 × 7 gives 28.
Thus, our original equation is now;
4(6 + 7)
Using distributive property, let's add the number in the bracket first to get;
4(13).
Now,we multiply out to get 52.

Working simultaneously, eight pumps fill in a pool in 32 hours. All pumps work at the same pace. If only half of the pumps are working, in how many hours will the pool be filled in?
Answers
Answer:
64 hours
Step-by-step explanation:
Since there are only half of the pumps that are working the time will double. 32x2 is 64
Answer: 16 hours
Step-by-step explanation
Step 1: Split 8 in half because we are using half the amount of pumps which is 4. Now we know the amount of pumps being used.
Step 2: Next we find the unit rate by dividing 32 and 8 to get 4
Step 3: Lastly we multiply 4x4 because 4 is the amount of pumps being used and the other 4 is the unit rate. Once we multiply we get 16 which is the answer: 16 hours
The FIFO method of computing equivalent units excludes the beginning inventory costs in computing the cost per equivalent unit for the current period.
Answers
Answer:
Yes
Step-by-step explanation:
The FIFO method of process costing assumes that the opening work in process is the first group of units to be processed and completed during the current period. The opening work in progress is charged separately to completed production and the cost per unit is based only on the current period costs and the production for the current period. The closing work in process is assumed to come from the new units started during the period.

8.) A line passes through the points (k, 4) and (3, -6). The line is perpendicular to
the graph of 5y + 4x = 8. What is the value of k?
Answers
Answer:
K = 43
Step-by-step explanation:
We'll begin by determining the gradient of the equation 5y + 4x = 8. This can be obtained as follow:
5y + 4x = 8
Rearrange
5y = 8 – 4x
5y = –4x + 8
Comparing 5y = –4x + 8 with y = mx + c, the gradient m is –4
Next, we shall determine the gradient of the line perpendicular to the line with equation 5y = 8 – 4x.
This can be obtained as follow:
For perpendicular lines, their gradient is given by:
m1 × m2 = – 1
With the above formula, we can obtain the gradient of the line as follow:
m1 × m2 = – 1
m1 = –4
–4 × m2 = – 1
Divide both side by –4
m2 = –1/–4
m2 = 1/4
Finally, we shall determine the value of k as follow:
Coordinate => (k, 4) and (3, –6)
x1 coordinate = k
y1 coordinate = 4
x2 coordinate = 3
y2 coordinate = –6
Gradient (m) = 1/4
m = (y2 – y1) / (x2 – x1)
1/4 = (–6 – 4) / (3 – K)
1/4 = –10 /(3 – K)
Cross multiply
3 – K = 4 × –10
3 – K = –40
Collect like terms
– K = – 40 –3
–k = –43
Divide both side by – 1
K = –43/–1
k = 43
