What is the solution to the following equation?
2(3х – 7) + 18 = 10
Answer:
x = 1
Step-by-step explanation:
2(3x - 7) + 18 = 10 ( subtract 18 from both sides )
2(3x - 7) = - 8 ( divide both sides by 2 )
3x - 7 = - 4 ( add 7 to both sides )
3x = 3 ( divide both sides by 3 )
x = 1

Solve the quadratic by factoring: 3x^2+36x+33=0
Answer:

Step-by-step explanation:
Rico opens an ice cream shop. The function f ff models the shop's net worth (in thousands of dollars) as a function of time (in months) after Rico opens it. Plot the point on the graph of f ff that corresponds to the shop's net worth when Rico opens it.
Answer: -5
Step-by-step explanation:
Based on the graph given, the point that on the graph that corresponds with the shop's net worth when Rico opened it is -5.
What was the shop worth when it was opened?The point that the shop was opened is represented by the value of the y axis when it was first crossed.
Looking at the graph, the line first intercepted the y axis at -5 which means that this was the shop's net worth when it was opened by Rico.

Ali has q quarters. Tom has four more quarters than Ali.
Drag and drop the expressions into the boxes to write an expression that represents the number of quarters Ali and Tom have together.
Response area + Response area
Answer: x(.25)+(4+x(.25))=y
Step-by-step explanation:
1. set up the equation-
Ali has an unknown amount of quarters so make that x.
We know quarters are 25 cents so .25 if he has one quarter you put that one quarter into x, 2 into x and so on
Tom has 4 more, since he has 4 more it is 4+x and one again times .25
2. that is it
A company produces electric insulators. The strength of the insulators is important since a broken insulator may cause a short circuit. Unfortunately, the strength varies significantly due to the material. Because of the expense, only a limited number of insulators could be tested. The engineers sampled 25 insulators (From a production run of 200), and conducted a destructive test to determine the force that was required to break the insulators. The mean value of this force was 1723 lbf with a sample standard deviation of 90 lbf. You may approximate the population standard deviation with the sample standard deviation for the following questions.
a. Determine if the population is large enough or if a finite population correction (FPC) factor is needed. If so, what is the FPC factor?
b. For 95% confidence, determine the margin of error (+ lbf)
c. For these conditions, estimate the range of the probable population mean. Provide lower and upper values. For 95% confidence, determine the margin of error ( Assume the same mean and sample standard deviation. What is one advantage and one disadvantage of using 50 insulators instead of 25 insulators?
d. lbf) if 50 insulators were tested.

Answer:
[tex]\mathsf{\: \frac{24}{35} }[/tex]
Step-by-step explanation:
Given the addition of two unlike fractions, [tex]\mathsf{\frac{2}{5} \: +\:\frac{2}{7} }[/tex] :
We could only add those two fractions if they have the same denominator.
In order to do so, we must determine their least common denominator (LCD), which happens to be 35.
Next, perform the following mathematical operations:
[tex](\mathsf{\frac{2}{5} \:\times\frac{7}{7}}) + (\mathsf{\frac{2}{7} \:\times\frac{5}{5}})[/tex] = [tex]\mathsf{\frac{14}{35} \:+ \:\frac{10}{35}}[/tex] = [tex]\mathsf{\: \frac{24}{35} }[/tex]
Therefore, the correct answer is Option 3: [tex]\mathsf{\: \frac{24}{35} }[/tex].

How many solutions does the system of equations below have? (PLEASE HELP)
y=−9x−2
y=−9x−2
Answer:
y= -54-2
y= -56 &
x= -54/ -9
x= 6
Step-by-step explanation:
y= -9x-2
-9x= y+2 divide bothe side by -9
x=y+2/-9
y= -9(y+2/ -9) -2 = (y+2)-2
y= -2(y+2)
y= -2y-4
y+2y= -4
3y= -4 divide bothe side by 3
y= -4/3
x=y+2/ -9
x= -4/3+2/-9
x= -2/3× -9
x=18/3
x=6
What is the approximate length of arc s on the circle below? Use 3.14 for r. Round your answer to the nearest
tenth
Answer:6.3 i believe
Step-by-step explanation:
Answer:
6.3
Step-by-step explanation:
circumference = 2πr
arc length = (included angle/360) * circumference
as an equation
s = (θ/360) * 2πr
s = (θ/180)πr
---------------------------
θ = 45
r = 8
s = (45/180) * 3.14 * 8
s = 6.28
rounded
s = 6.3

Choose the correct answer below.
A.
about 10 years
B.
about 6 years
C.
about 3 years
D.
about 1 year
Answer:
B
Step-by-step explanation:
Use the amortisation formula:
A = P (r(1+r)^n)/((1+r)^n - 1)
swap in your numbers
p = 969.16
A = 20
n = 0.1524/12
20 = 969.16((0.1524/12) (1+(0.1524/12))^n) / ((1+(0.1524/12))^n - 1)
Then solve for n
n = 72 months
n = 6 years
