1. Louis ran a race in 2.4 minutes. Laura ran the same race in 124 seconds. What is the difference between the two times?​

Answers

Answer 1
Laura: 124 seconds is 2 minutes and 4 seconds.

Louis: 2.4 minutes is 2 minutes and 24 seconds (0.4 minute is 24 seconds)

So, the difference between the times is 20 seconds. Laura was 20 seconds faster.
Answer 2

Answer:

20 sec

Step-by-step explanation:

2.4 in = 144 sec

124

insert one pair of brackets only to make the following statement correct 6 +5*10-8=16

Answers

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.

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?

Answers

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

Step-by-step explanation:

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

Answer:

it's the first one j=h+9

Step-by-step explanation:

as you can see the pattern you will look at all the answer choices and eliminate them one by one since it is the first answer you will be adding the numbers from the input by 9 and it will give you the output as you can see the other answers they are either multiplying by 9 or you just can't add them with the equation.

Find the two solutions to the equation below.
(x – 3)(x − 2) = 0
Anyone know how to do it

Answers

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.

The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB In slope-Intercept form that contains point (3,-2). (4 points)
O y = 2x + 4
O y = 2x - 8

Answers

Answer:

The equation of a parallel line in the slope-Intercept form that contains the point (3,-2) is:

y = 2x- 8

Step-by-step explanation:

The slope-intercept form of the line equation

y = mx+b

where

m is the slopeb is the y-intercept

Given the equation of a line

y = 2x + 4

comparing with the slope-intercept form of the line equation

The slope of the line AB is m = 2

We know that the parallel lines have the same slope.

Thus, the slope of the new line is also 2.

now we have,

The slope of new line m = 2The point = (3, -2)

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 2 and the point (x₁, y₁) =  (3, -2)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

y - (-2) = 2(x - 3)

y + 2 = 2x - 6

subtracting 2 from both sides

y + 2 - 2 = 2x - 6 - 2

y = 2x- 8

Therefore, the equation of a parallel line in the slope-Intercept form that contains the point (3,-2) is:

y = 2x- 8

What is percentage?

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%

Answers

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
