Answer:

1/8 half-gallon or 1/16 full gallon

Step-by-step explanation:

Emma and her 3 friends= Four people

Four people shared 1/2 gallon= 1/2 divided by 4

1/2 divided by 4= 1/8

Each person got 1/8 of the half gallon.

This would mean that out of a FULL gallon, they would get 1/16

Answer:

3[tex]\frac{3}{4}[/tex] days

Step-by-step explanation:

Let the amount of work be x.

Daniel:

10 days = x

1 day = [tex]\frac{1}{10}[/tex]x

Father:

6 days = x

1 day = [tex]\frac{1}{6}[/tex]x

Together:

1 day = [tex]\frac{1}{10}[/tex]x + [tex]\frac{1}{6}[/tex]x

        = [tex]\frac{6}{60}[/tex]x + [tex]\frac{10}{60}[/tex]x

        = [tex]\frac{16}{60}[/tex]x

        = [tex]\frac{4}{15}[/tex]x

No. of days = [tex]\frac{15}{15}[/tex]x ÷ [tex]\frac{4}{15}[/tex]x

                   = [tex]\frac{15}{15}[/tex]x × [tex]\frac{15}{4}[/tex]x

                   = [tex]\frac{225}{60}[/tex]

                   = 3[tex]\frac{3}{4}[/tex]

Answer:

35 girls

Step-by-step explanation:

First add the ratios together ( 3+5) this will give you 8. Then divide the total number of students by 8, this will get you 7. Now multiply 7 to 3 and multiply 7 to 5. As the ratio of boy to girl is 3 to 5, to find how many girls are in the school play we multiply 7 to 5. This makes 35 girls.

If you want to check, 7 x 3 =21 boys and 7 x 5=35 girls. 35 +21= 56 (the total number of students).

Answer:

The answer is below

Step-by-step explanation:

Which equation in slope-intercept form represents a line that passes through the point (2,3) and is perpendicular to the line y−9=23(x+7)

Solution:

The equation of a line in slope intercept form is given as y = mx + b, where m is the slope and b is the y intercept.

Given a line y−9=23(x+7)

y - 9 = 23x + 161

y = 23x  + 170. The slope of this line comparing with y = mx + b gives m = 23

Two lines are perpendicular if the product of their slope gives -1.

Let [tex]m_1[/tex] be the slope of the perpendicular line, hence:

[tex]m_1(23)=-1\\\\m_1=\frac{-1}{23}[/tex]

Since the perpendicular line passes through (2, 3), we can get its equation using:

[tex]y-y_1=m_1(x_x_1)\\\\y-3=\frac{-1}{23}(x-2)\\\\y= \frac{-1}{23}x+\frac{2}{23}+3\\\\ y= \frac{-1}{23}x+\frac{71}{23}[/tex]

Answer and Step-by-step explanation:

We are not given the function in question, but in order to explain, will form a function. Suppose f(x) = 3x + 2.

If f(x) = 17, then

3x + 2 = 17, to find the value of x, we have solve for x in the equation.

3x = 17 – 2

3x = 15

x = 5

This is the method that can be used to solve problems of this nature.

Answer:

They intersect at an x value of 2

Step-by-step explanation:

Rewrite the equations into slope y-int form:

-2x + y = -6

y = 2x - 6

x + 2y = -2

2y = -2 - x

y = -1/2x - 1

Next, set the two equations as equal and solve for x:

2x - 6 = -1/2x - 1

2x + 1/2x = -1 + 6

4x + x = -2 + 12

5x = 10

x = 2

7/8 yards more blue ribbon was bought

The given parameters are

Blue ribbon = 1 3/8 yards

Green ribbon = 1/2 yards

The amount of excess ribbon that is blue is

Excess = Blue ribbon - Green ribbon

So, we have

Excess = 1 3/8 yards - 1/2 yards

Evaluate the difference

Excess = 7/8 yards

Hence, 7/8 yards more blue ribbon was bought

Answer:

4 and 7

Step-by-step explanation:

There are probably several ways to do this but this is how I did it:

First, I listed all the number combinations, that added together equaled 11.

This is what it looked like:

1, 10

2, 9

3, 8

4, 7

5, 6

6, 5

7, 4

I stopped here since the next step would be to double the first number and 8*2 would already be more than 15.

Then, I doubled the first number and added the second number to it, when I saw that didn't equal 15, I eliminated that possibility and moved on to the next set of numbers. When I reached 4, 7 I saw that 4*2 equaled 8 and 8 plus 7 equals 15 so I had the answer.

There are probably much more efficient ways to do this but this is how I did it.

Hope it helped!

The first number is 4 and second number is 7.

Let us consider that first number is x and second number is y.

            [tex]2x+y=15\\\\x+y=11[/tex]

Substitute [tex]y=11 - x[/tex]in equation [tex]2x+y=15[/tex]

        [tex]2x+11-x=15\\\\x=15-11=4[/tex]

So,   [tex]y=11-x=11-4=7[/tex]

Step-by-step explanation:

You are given a pair of alternate interior angles which are both right angles and are formed by a transversal line cutting two lines. That means the pair of angles are congruent.

Use the Alternate Interior Angles Theorem and by that those two lines must be parallel.

The amounts for the other three partners are $25000, $100000, and $200000.

The amount that the other people will share will be:

= $400000 - $50000

= $350000

Therefore this will be divided as follows:

A = 2/(2+4+8) × $350000

= 2/14 × $350000

= $25000

B = 4/14 × $350000

= $100000

C = 8/14 × $350000

= $200000

Therefore, the amounts for the other three partners are $25000, $100000, and $200000.

Answer:

The cost of the  electric scooter after the discount and

sales tax will be: $248.24

Step-by-step explanation:

The regular price of an electric scooter = $290

Discount = 20%

The discount price =  20% × 290

                                = 20/100 × 290

                                = $58

The price after the discount = $290 - $58 = $232

Sales tax = 7%

Sales tax amount = 7% × 232

                         = 7/100 × 232

                         = $16.24

The cost after the discount and sales tax = $232 + $16.24

                                                                      = $248.24

Thus, the cost of the  electric scooter after the discount and

sales tax will be: $248.24

The required rate of the level of change of water in the swimming pool is 1 / 3 level per hour.

Given that,
The swimming pool is being filled with a hose.
The pool's water level rises 4 inches in hours.
To determine the rate per hour of the water level change.

Here,
Let 1 level of pool = 1 feet = 12 inches
The pool's water level rises 4 inches in hours. So, ti will rises 12 inches in 3 hours, which implies level change after 3 hours
Now the rate of level change of water = 1 / 3 level per hour
