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%

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

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

Hence, the calculated difference is $2500

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

             =(9+9)/2

             = 18/2

              = 9

Answer:

27/3 = 9

Step-by-step explanation:

"How many times does 3 go into 27?" is the same as asking "How much is 27 divided by 3?" Thus, the answer can be calculated as follows:

27/3 = 9"How many times does 3 go into 27?" is also the same as asking "What (x) do you multiply by 3 to get 27?" We solve the problem with an easy algebra equation:

3(x) = 27

x = 9

Tip: When you get a question like "How many times does 3 go into 27?", just think of it as how many times you can fit 3 into 27.

Answer:

4sqrt(2) + 1

Step-by-step explanation:

Well you know that cos 0 is 1

this means that a+b = 9

cos 60 is 1/2

this means 1/2 a + b = 5

a = 8

b = 1

now plug in for x = 45

cos 45 = sqrt(2)/2

After raising the walls of the building of height 2cm 5 times the height of the wall will be 10cms.

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.

15

Step-by-step explanation:

The value of f(x) when x = -5 is 15

From the equation

f(x) = 5x + 40

Substitute the value of x = -5

We have,

f(x) = 5(-5) + 4=

f(x) = -25 + 40

f(x) = 15

Therefore, the value of f(x) when x = -5 is 15

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.

Gray gob you are correct

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.

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.

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.

c.) Three dollars more than the quotient of $0.50 and the number of miles is nine dollars and fifty cents.  

d.) The product of the number of miles and the sum of $3 and $0.50 is equal to $9.50.

e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Answers

The correct answers are:

b

e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents.

Step-by-step explanation:

The formula written by the driver is: 3.00 + 0.50 m = 9.50

where m = number of miles travelled

This means that when the product of 0.50 and the number of miles travelled 'm' is added to $3, the result is 9.50

And this is the same explanation as the following options:

a.) Three dollars($3) plus $0.50 times the number of miles is equal to nine dollars and fifty cents($9.50).

e.) e.) The sum of three dollars and the product of 50 cents times the number of miles is nine dollars and fifty cents;

note that 50 cents is the same as $0.50
