Answer:

$779.1

Step-by-step explanation:

Original price = $980

Michelle bought a computer that was 25% off the regular price of $980.

Amount Michelle bought it = 75% of $980 = 0.75 * 980 = $735

If a 6% sales tax was added to the cost of the computer,

Sales tax = 6% of $735 = 0.06 * 735 = $44.1

what was the total price Michelle paid for the computer?

Total Price = Amount Michelle bought it + Sales Tax

Total Price = $735 + $44.1 = $779.1

Answer:

Step-by-step explanation:

To calculate the total that will be paid we first need to calculate how much the computer cost with the discount applied. First, we need to turn the percentage into a decimal by dividing by 100.

25% /100 = 0.25

Now we multiply the regular price of the computer by the remainder of 1 minus 0.25

980 * (1 - 0.25) = $735

Now that we have the discounted price we need to multiply this by the sales tax in decimal form after adding 1 to the decimal.

6% / 100 = 0.06

735 * (1 + 0.06) = 779.10

Finally, we can see that the total price that Michelle paid for the computer is $779.10

Answer:

is 40.9

Step-by-step explanation:

The percent of change in the value of the car is 40.88%

A percentage is a portion of a whole expressed as a number between 0 and 100 rather than as a fraction.

Given that, Manny bought a car for $32,985. Five years later, the car was worth $19,500.

Percentage change = (32985-19500)/32985*100 = 40.88%

Hence, The percent of change in the value of the car is 40.88%

Answer:

10 boys to 5 girls you got to divide

Step-by-step explanation:

you have to put 50 over 25 and simplify them by 5 and you get 10 boys to 5 girls I think.

  Class made up of 50 boys and 25 girls will have boys to girls ratio as 2 : 1

Ratio of the boys to girls in a class can be evaluated by the expression,

Ratio = [tex]\frac{\text{Total number of boys}}{\text{Total number of girls}}[/tex]

Given in the question,

Number of boys = 50

Number of girls = 25

Substitute these numbers in the expression and simplify the fraction,

Raio = [tex]\frac{50}{25}[/tex]

        = [tex]\frac{2}{1}[/tex]

        = 2 : 1

   Therefore, ratio of boys to girls in the class is 2 : 1

Answer:

I chose B. 3

Step-by-step explanation:

I chose B because the person is either staying still, not moving, or something of the sort.

Answer:

You have two brackets..divide them as

x-3=0 and x-2=0

so x=3, x=2

The solutions to the equation ( x – 3 )( x − 2 ) = 0 using factors equal to zero are x = 3 and x = 2.

To find the solutions to the equation ( x – 3 )( x − 2 ) = 0, we set each factor equal to zero and solve for x. This is because the product of two factors is equal to zero only if at least one of the factors is zero.

Setting ( x – 3 ) = 0:

x – 3 = 0

x = 3

Setting ( x − 2 ) = 0:

x − 2 = 0

x = 2

Therefore, the solutions to the equation ( x – 3 )( x − 2 ) = 0 are x = 3 and x = 2.

Answer:

X=18

Step-by-step explanation:

(1/2)*x-7 = (1/3)*(x-12) // - (1/3)*(x-12)

(1/2)*x-((1/3)*(x-12))-7 = 0

(-1/3)*(x-12)+(1/2)*x-7 = 0

x/2-1/3*(x-12)-7 = 0

(-1/3*2*(x-12))/2+x/2+(-7*2)/2 = 0

x-1/3*2*(x-12)-7*2 = 0

1/3*x-14+8 = 0

1/3*x-6 = 0

(1/3*x-6)/2 = 0

(1/3*x-6)/2 = 0 // * 2

1/3*x-6 = 0

1/3*x-6 = 0 // + 6

1/3*x = 6 // : 1/3

x = 6/1/3

x = 18

Answer:

6+5*(10-8)=16

Step-by-step explanation:

Using BODMAS multiplication takes precedence over addition and subtraction so as it stands it would be calculated as 6 + (5*10) - 8. To get the answer 16 it would be 6 + 5(10 - 8) Solving the brackets first, this gives 6 + (5*2) which gives 16.

To go from 3 to 12, add 9 to 3. Add 9 to 4 to get 13. Add 9 to 5 to get 14.

In each case, add 9 to the value of h to get j.

j = h + 9
