Answer:

(8)(0.25)−1+14

=15

Step-by-step explanation:

Answer:

2640 feet in a minute.

Step-by-step explanation:

Since the car is going 30 miles per hour, and there are 5280 feet in one mile, you would multiply 30 by 5280.

30 * 5280 = 158400

So 154800 feet = 30 miles.

Since you want to find out how fast a car going 30 miles per hour is traveling in feet per a minute, you would divide 154800 feet by 60, since there are 60 minutes in an hour.

154800 / 60 = 2640.

So 2640 feet in a minute.

If you want to check this, you can do 2640 * 60, which indeed equals 154800.

Hope this helps.

Answer: 0.9375 or 15/16 cup of water

Step-by-step explanation:

The plant has been getting 25% too much water which means that it has been getting 25% more than 3/4.

= 25% * 3/4

= ‭0.1875‬ cup of water

Water plant has been getting;

= 3/4 + ‭0.1875‬

= 0.9375 or 15/16 cup of water

you get the numbers 20 and 25 respectively.

Answer:

The value is  [tex]m = 0.9022[/tex]

Step-by-step explanation:

From the question we are told that

    The length of the treads is  [tex]a = 9 \ inch[/tex]

     The length of the risers is  [tex]b = 8.12 \ inch[/tex]

Generally the slope of the staircase is

         [tex]m = \frac{b}{a}[/tex]

=>       [tex]m = \frac{8.12}{9}[/tex]

=>       [tex]m = 0.9022[/tex]

Answer:

y = (1/6)x - 5

Step-by-step explanation:

Substituting m for the the slope:

y = (1/6)x + b

Plugging in the values showed in the point (x = 12, y = -3):

-3 = (1/6)12 + b

-3 = 2 + b

b = -5

y = (1/6)x - 5

The number to add is (11/2)^2 = 121/4

Step-by-step explanation:

Here, we want to know the number that will complete the square

We rewrite the equation as follows;

x^2 + 11x = -30

x^2 + 11x + (11/2)^2 = -30 + (11/2)^2

x^2 + 11x + 121/4 = -30 + 121/4

Answer: The expression is 5 x (6 - 3)

Step-by-step explanation:

Answer:

The equations should have been added up to equal 180 instead of being set to equal each other. The two are supplementary angles, which can be seen due the rule that a pair of interior angles on the same side of the transversal is supplementary. To fix this issue from the work that they did, they should subtract the 140 from 180, so the correct measure of DKH is actually 40 degrees.

Step-by-step explanation:

The expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.

It is defined as the combination of constants and variables with mathematical operators.

We have an expression:

= 2(14x - 3y + 28x + 12.2 - 5y - 17.5)

= 28x - 6y + 56x + 24.4 - 10y - 35

Adding like terms

= 84x - 16y -10.6

Thus, the expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.

The reason why both graphs are parallel because they have the same slope but different y-intercept.

Think about it. If both graphs have same slope and same y-intercept. The graph will intercept each others infinitely.

Then if we change the y-intercept into any numbers that aren't the same as another equations for ex.

y = -5x+1 and y = -5x+10

then we will get the parallel graph. Or if you solve the equation, the equation will not be true, thus giving the graph parallel.

But if it is y = -5x+1 and y = -5x+1 which both are the same graph. Then the graph will intercept each others infinitely. Or if we solve the equation, we will get 0 = 0 which makes the equation true for all real numbers.

Therefore, the reason why both graphs are parallel is because that they have the same slope but different y-intercept.

That's all.

Step-by-step explanation:

The amount of money left after purchasing the bike is $17.32

The cost of the new bike is $142.68

I need to save for the new bike and i decided to mow the neighbour's yard

The money paid is $40, this will be done for 4 weeks

At the end of the four weeks, the money i will get can be calculated as follows

= 40 × 4

= 160

To calculate the money left, let's subtract the cost of the bike from 160

= 160 - 142.68

= 17.32

Hence the amount of money left after buying the bike is $17.32
