He raises the walls of the building
by 2 centimeters five times. By how
many centimeters does Bryce raise
the walls all together?
(A) 2 cm
© 10 cm
(B) 5 cm
D20 cm
After raising the walls of the building of height 2cm 5 times the height of the wall will be 10cms.
What is multiplication ?Multiplication is a short hand of addition like if we have to add 2 by100 times it is same as multiplying 2 with 100 which is 200.
According to the given question Bryce is making a model building.
Said that he raises the walls of the building by 2 centimeters five times.
So, Either we can sum 2 centimeters 5 times which is (2 + 2 + 2 + 2 + 2) which is
= 10cms.
Or we can multiply the height of the building which is 2 cm by the no. of times he raised it which is 5.
∴(2×5) = 10cms.

A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled.
Answer:
Value of miles traveled (m) = 13 mile
Step-by-step explanation:
Given:
Equation
3.00 + 0.50 m = 9.50
Find:
Value of miles traveled (m)
Computation:
3.00 + 0.50 m = 9.50
0.50 m = 9.50 - 3.00
0.50 m = 6.50
m = 6.50 / 0.50
m = 13
Value of miles traveled (m) = 13 mile
Answer:
The question is not complete, below is the complete question:
A taxi driver wrote a formula to represent the mileage and fee for his last customer. He wrote the equation 3.00 + 0.50 m = 9.50, where m represents the number of miles traveled.
Which statement shows the meaning of the driver's equation? Check all that apply.
a.) Three dollars added to $0.50 is the same as $9.50.
b.) Three dollars plus $0.50 times the number of miles is equal to nine dollars and fifty cents.

Ten children measured how high they could jump. The results they recorded, in inches, were as follows: 8, 9, 8, 6, 8, 12, 9, 10, 11, 16 What is the median of these measures?
A. 8 in.
B. 9 in.
C. 9.5 in.
D. 10 in.
E. None correct
Answer:
b) 9 in
Step-by-step explanation:
To find median arrange the data in ascending order and count the number of data's. if the total number of data is odd number, then (n/2)th term is the median.
If the total number of data is even, then Average of (n/2)th term and (n/2)+1 th term is the median
Ascending order:
6, 8, 8 , 8 , 9 , 9 , 10 , 11 , 12 , 16
total = 10. so even number
Median = average of 5th term and 6th term

The graph of y = f(x) is shown below. Find the value of f(5)
Answer:
5
Step-by-step explanation:
WHen f(x) = f(5)
x=5
therefore y = 5
Hope that helped!!! k
Answer:
5
Step-by-step explanation:
Asking for f(5) is the same as asking for the value of f(x) when x = 5.
So we're looking for the y-value our graph gives when x = 5.
Find 5 on the x-axis and trace the line up to the graph, and then left to find the y-value. Here, it happens to be 5.
if we represent the length of a line by a, how may we represent the length of a line that is 3 inches shorter. If the combined length of the two lines is 15 inches, what is the length of each line?
Answer:
The lines' lengths are: 8 inches and 5 inches.
Step-by-step explanation:
Calling "a" the length of the line, a line that is 3 inches shorter can be written in math terms as:
a - 3
If the combined (added) length of these two lines is 15 inches, then we can write:
a + (a - 3) = 15
a + a - 3 = 15
2 a - 3 = 15
2 a = 15 + 3
2 a = 18
then
a = 18/2 = 9
Therefore, the length of one line is 8 inches, and the length of the shorter line is:
8 - 3 = 5 inches

The number of customers to visit a local small businesses 51,200 and has been continuously declining at a rate of 3.8 each year what is the approximate number of customers that visit the business in 14 years
Answer:
=30076 customers
Step-by-step explanation:
Number of customer= 51,200
rate of declination=3.8 %= 0.038
We will use the expresion below in calculating the approximate number of customers that visit the business in 14 years.
A=Pe^(rt)
Where P=initial amt,
r=annual rate of growth or decline,
A=amount after t years.
37800=Pe^.017t
51200=Pe^0.038
P= 51200/e^(0.038*14)
But e^(0.038*14)= 1.7023
P= 51200/1.7023
P=30076
Approximate number of customers that visit the business in 14 years≈30076

A 11 L solution that was 25 % vinegar was mixed with a 12 L solution that was 67 % vinegar. Find the new concentration of vinegar.
Answer:
46.91%
Step-by-step explanation:
The first solution contains 11 * 0.25 = 2.75 L of vinegar
The second solution contains 12 * 0.67 = 8.04 L of vinegar
When mixed together, that adds up to 8.04 + 2.75 = 10.79 L of vinegar
The total volume of the combined solutions is 11 + 12 = 23 L of solution
So the new concentration is 10.79/23 ≈ 0.4691 ≈ 46.91%
Sharika can finish the work in 6 days and Palkey can do the same work in 8 days. They both worked together for for 2 days then Palkey left the work. How many days will Sharika take to finish the remainig work.
Answer:
Sharika needs 2.5 days to finish the remaining work
Step-by-step explanation:
Sharika can do a work in 6 days palkey can do it in 8 days
Then the amount of work sharika can do in 1 day = 1/6
And the amount of work palkey can do in 1 day = 1/8
The amount of work both of them can do together in 1 day = 1/6 + 1/8
= 7/24
The amount of work both of them can do together in 2 day = (2× 7/24)
= 7/12
Since Palkey left the work,the amount of
work remaining for Sharika to do alone = (1 - 7/12 )
= 5/12
The number of days Sharika take to finish the remainig work. = (5/12 ÷ 1/6 )
= 5/2 days
Therefore, Sharika needs 2.5 days to finish the remaining work.

The length of a rectangle is 7 inches less than its width. The perimeter of the
rectangle is 54 inches. Find the length and the width of the rectangle. Explain your
reasoning.
Answer:
8 in.
Step-by-step explanation:
Perimeter of a rectangle, P = 2(L + W)
Value of P = 46.
Length is 7 inches less than the width. This translates to L = W - 7
Substitute L = W - 7 into the perimeter equation, you get
46 = 2(W - 7 + W)
46 = 2(2W - 7)
46 = 4W - 14
4W = 60
W = 60 / 4 = 15 in
L = W - 7 = 15 - 7 = 8 in
The width and length of the rectangle in inches are 17 and 10 respectively.
What is perimeter ?Perimeter is the sum of the lengths of all the sides of a given plane figure.
According to the given question the length of a rectangle is 7 inches less than its width.
Assuming the width of the rectangle is x inches.
∴ From the given data length of the rectangle is ( x - 7) inches.
Given perimeter is 54 inches.
We know perimeter of a rectangle is 2( length + breadth).
∴ 2{ x + ( x - 7) } = 54.
2 { 2x - 7 } = 54
4x - 14 = 54
4x = 54 + 14
4x = 68
x = 17.
So, the width of the rectangle is 17 inches and length of the rectangle is (17 - 7) inches which is 10 inches.

[tex]= -4(2x)-4(-y)+y+5(x)+5(y)\\\\= -8x+4y+y+5x+5y[/tex]
Collect the like terms:
[tex]= -8x+5x+4y+y+5y[/tex]
Sum up the resulting expression
[tex]= -8x+5x+4y+y+5y\\= -3x+10y[/tex]
Hence the required expression on simplification is -3x+10y
