A plumber charges $75 for the service call and $25 per hour (h) for repairs. Write an algebraic expression to represent the total bill for all plumbing services.
A.
(75 + 25)h
B.
75 + 25h
C.
75h + 25
D.
75 + 25 + h
Answer:B i think if wrong im so sorry
Step-by-step explanation:
Answer:
B 75+25h
Step-by-step explanation:
$75 is the first charge for the service and is constant. $25(per hour) is not constant and changes as the time (hours) changes. That's why it has a h next to it, the h is the variable to hold the place for the hours that would be multiplied in the problem.

Answer:
C)
[tex] \frac{1}{2} [/tex]
Step-by-step explanation:
Your problem should be set up like so:
[tex] \frac{1}{6} \div \frac{2}{6} [/tex]
When dividing fractions you multiply by the reciprocal of the second fraction. Therefore your question changes to this:
[tex] \frac{1}{6} \times \frac{6}{2} [/tex]
You multiply as across as normal and you'll end up with
[tex] \frac{6}{12} [/tex]
Which when simplified gives you
[tex] \frac{1}{2} [/tex]

Answer:
m<A=94
Step-by-step explanation:
(2x+10)+(2x+2)=180
4x+12=180
-12 -12
4x=168
/4 /4
x=42
m<A= 2x+10
m<A=2(42)+10
m<A=84+10
m<A=94
Check:
Add m<A and m<B which should equal 180.
m<B=2x+2
m<B=2(42)+2
m<B=84+2
m<B=86
94+86=180
A circle has a circumference of 6. It has an arc of length 1.
What is the central angle of the arc, in degrees?
Answer:
60 degrees
Step-by-step explanation:
s = r (theta)
(theta) = s/r
= 1 / (3/π) = π/3
as a degree π/3 x 180/π = 60
60 degrees
*Circumference = 2πr
6 = 2πr
r = 6/2π = 3/π

what is 2.1 times 3.2 find the missing partial products HELP.
Given:
The area model for [tex]2.1\times 3.2[/tex].
To find:
The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.
Solution:
2.1 can be written as 2 and 0.1 on the left side of the area model.
3.2 can be written as 3 and 0.2 on the top of area model.
Area of the four parts of the area model are:
[tex]2\times 3=6[/tex]
[tex]2\times 0.2=0.4[/tex]
[tex]0.1\times 3=0.3[/tex]
[tex]0.1\times 0.2=0.02[/tex]
The complete area model is shown below.
After adding all areas of the area model, we get
[tex]6+0.4+0.3+0.02=6.72[/tex]
Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.

Answer:
x = 6
Step-by-step explanation:
3x + 4 = 22
subtract 4
3x = 18
divide by 3
x = 6
Answer:
x=6
Step-by-step explanation:
Subtract 4 from each side of the equation to get 3x=18. divide 18 by 3 to get 6, and divide 3x by 3 to get x. x=6
solve the equation for x. square root of x+9=11

If a pollster wants to increase their ability to predict the outcome of an election, one thing they can do is increase the
size of the sample. By doing so:
O nonresponse will be eliminated.
the results of the sample will be unbiased.
the variability of the sample results will be reduced, giving greater precision in the estimate.
the pollster can be certain that he can correctly predict the outcome of the election.
Answer:
the variability of the sample results will be reduced, giving greater precision in the estimate.

what is the product of 4n/4n-4 * n-1/n+1
Answer:
x/x+1
Step-by-step explanation:
[tex]\frac{4n}{4n-4} * \frac{n-1}{n+1}[/tex]
start by reducing the 4n-4 by distributing the 4 to make it 4(x-1)
So the fraction would be 4n/4(x-1)
Now that you have done that you can easily take off the 4 as well as the x-1 thats now in the parentheses
The new equation would be
n*n-1/n+1
Now just multiply:
x/x+1
Answer:
B.) n/(n+1)

A grocery store recently sold 12 cans of soup, 6 of which were black bean soup. Based on experimental probability, how many of the next 20 cans sold should you expect to be black bean soup?
Answer: 10
Step-by-step explanation: the probability of selling black bean soup is 1/2 because 6/12=1/2. You should multiply 20 by 1/2 to find how many of the next 20 are expects to be black bean.
Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?
Answer:
9500
Step-by-step explanation:
Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?
The best estimate of a population is calculated as:
= N = mn/k
Where N = Estimate of the population
m = 950 pike
n = 100 pike
k = 10 tags
= 950 × 100/10
= 9500
The best estimate of he population = 9500
A rectangular city lot has an area of 1000 square meters. If the length of the lot is 10 meters more than twice its width, find its length and width.
Answer: l=50 m, w=20 m
Step-by-step explanation:
Given
A rectangular city has an area of [tex]1000\ m^2[/tex]
Also, length is 10 m more than twice its width
suppose width is w
So, length is given by
[tex]\Rightarrow l=10+2w[/tex]
The area is given by
[tex]\Rightarrow A=l\times w\\\Rightarrow 1000=(10+2w)\times w\\\Rightarrow 2w^2+10w-1000=0\\\Rightarrow w^2+5w-500=0\\\Rightarrow w^2+25w-20w-500=0\\\Rightarrow (w+25)(w-20)=0\\\therefore w=20\ m\\l=10+2w=10+2\times 20=50\ m[/tex]
