Rita runs 3 miles in 25 minutes. At the same rate, how many miles would she run in 20 minutes?

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]

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

Step-by-step explanation:

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 equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.

Two lines with slopes m₁ and m₂ are parallel when m₁ = m₂ and perpendicular when m₁*m₂ = -1.

In the question, we are asked for the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12.

The given line can be shown as:

x - 4y = 12,

or, - 4y = - x + 12,

or, y = x/4 - 12/4,

or, y = x/4 - 3.

Comparing it to the slope-intercept form of a line, y = mx + b, we get the slope, m = 1/4.

The line parallel to this will also have the slope, m = 1/4.

The required line passes through the point (8, -4).

Using the one-point formula, (y - y₁) = m(x - x₁), we can write the required equation as:

y - (-4) = (1/4)(x - 8),

or, y + 4 = x/4 - 2,

or, y = x/4 + 2,

or, x/4 - y = -2,

or, x - 4y = - 8.

Thus, the equation of the line that passes through the point (8, -4) and is parallel to the line x - 4y = 12 is x - 4y = - 8.

Answer:

His songs were played 4 times in a commercial, and 3 times in a movie.

Step-by-step explanation:

Let x represent the number of times his songs were played in a commercial, and y represent the number of times his songs were played in a movie.

Since we know Owen's songs were played on 4 more commercials than in movies, we can write the expression

x = y + 4

Owen gets $50 every time one of his songs is played in a commercial and $140 every time one of his songs is played in a movie, so we can add these numbers into the equation below.

140y + 50x = $770

We can use the equation two lines above and substitute it into this equation so it now becomes:

140y + 50(y +4) = 770

Now we operate the equation so it becomes:

140y + 50y + 200 = 770

Now we reduce and add like terms.

190y = 770 - 200 = 570

190y = 570

570 / 190 = 3 (3 movies)

x = y + 4 = 7

y = 3

x = 3 + 4 = 7

So therefore Owen's songs were played 4 times in a commercial (x), and 3 times in a movie. (y)

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).

(3.012 x 10−8) + (4 x 10−8)=

(3.012+4) x 10−8=

(3.012+4.000) x 10−8=7.012 x 10−8 ==> Option 3

Calculating the expression (3.012 x 10−8) + (4 x 10−8) is 7.012 x 10^(-8).

To calculate (3.012 x 10^(-8)) + (4 x 10^(-8)), we can add the numbers as follows:

(3.012 x 10^(-8)) + (4 x 10^(-8)) = (3.012 + 4) x 10^(-8) = 7.012 x 10^(-8)

Step-by-step explanation:

so, the whole question basically asks you to convert the units back and forth, (its very similar to the conversion of currency) & There are many ways to do this, ill show one of the methods, if u don't understand then i can show u another way....

ill do the first two-

COUCH-

1 inch: 0.5 ft

x inch:7ft  { x is the missing value ((model length of couch)) }

Now cross multiply

0.5x=7*1

x=7/0.5

x=14 inches

CHAIR-

1 inch: 0.5 ft

6 inch: x

Do the same step -Cross multiply

1x=0.5*6

x=3/1

x=3

The value of function f when x is (-3) is 9.

To solve the value of function for the value of x as -3, we will simply keep the value of x in the equation.

Rewriting the equation

f(x) = -x + 6

Keep the values of x in the above equation

f(x) = - (-3) + 6

Adding the two negative signs, hence, the value will be 3.

f(x) = 3 + 6

Performing addition to find the value of f(x) when value of x is (-3)

f(x) = 9

Therefore, the value of f(x) is 9.
