If you can buy 3 items for 9.00, how much will it cost for 5 items
Answer:
15.00
Step-by-step explanation:
since you buy 3 items for 9.00, then you can buy one item for 9.00/3 = 3.00
therefore, for 5 items, it will be
cost of one item * 5
which is, 3.00 * 5 = 15.00

Michelle bought a computer that was 25% off the regular price of $980. If a 6% sales tax was added to the cost of the computer, what was the total price Michelle paid for the computer?
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

A class is made up of 50 boys, 25 girls,
What is the ratio of boys to girls.
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
Calculations for the ratio of boys to girls:
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

1/2×-7=1/3(×-12) solve
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

The scatter plot shows the average weights of children at a pediatrics clinic. Write an equation for the trend line, using the points (5,40) and (0,10).
Given:
The points are (5,40) and (0,10).
To find:
The equation for the trend line using the given points.
Solution:
If a line passes through two points, then the equation of the line is:
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
Two points are (5,40) and (0,10). So, the equation of trend line is
[tex]y-40=\dfrac{10-40}{0-5}(x-5)[/tex]
[tex]y-40=\dfrac{-30}{-5}(x-5)[/tex]
[tex]y-40=6(x-5)[/tex]
[tex]y-40=6x-30[/tex]
Adding 40 on both sides, we get
[tex]y=6x-30+40[/tex]
[tex]y=6x+10[/tex]
Therefore, the equation of trend line is [tex]y=6x+10[/tex].
