Some students did treadmill workouts, each one running at a constant speed. Answer the questions about their workouts. Tyler ran 4,200 meters in 30 minutes. • Kiran ran 6,300 meters in 1 hour. . Mai ran 6.3 kilometers in 45 minutes. 2. At what rate did each of them run?

Answers

Answer 1

Answer:

rate of Tyler = 8.4 Km/hour

rate of Kiran = 6.3 Km/hour

rate of Mai = 8.5 Km/hour

Step-by-step explanation:

Rate is the speed with which each ran

speed = total distance covered/total time taken to cover that distance

we will use unit  km/hour for speed calculation

_____________________________________________________________

For Tyler

distance = 4200 m

1000 m = 1 km

4200 m = 1/1000 *4200 km = 4.2 KM

time = 30 minutes

60 mins = 1 hour

30 minutes = 1/60 *30 hour = 0.5 hours

thus,

speed/rate of Tyler = 4.2 KM/0.5 hours = 8.4 Km /hour

_____________________________________________________

For Kiran

distance = 6300 m

1000 m = 1 km

6300 m = 1/1000 *6300 km = 6.3 Km

time = 1 hour

thus,

speed/rate of Kiran = 6.3KM/1 hours = 6.3Km /hour

_____________________________________________________

For Mai

distance = 6.3 Km

time = 45 minutes

60 mins = 1 hour

45 minutes = 1/60 *45 hour = 0.75 hours

thus,

speed/rate of Mai = 6.3KM/0.75 hours = 8.5 Km /hour

This equation can be written as :-

= 6 + 4x = x + 15

= 4x+6=x+15

= 4x + 6 − x = x + 15 − x

= 3x + 6 = 15

= 3x + 6 − 6 = 15 − 6

= 3x = 9

= 3 x 3 = 9

= x = 9 ÷ 3

= x = 3

Using this , let us solve the equation :-

= 6 + 4 × 3 = 3 + 15

= 6 + 12 = 3 + 15

= 18 = 18

Therefore , 6 + 4x = x + 15 = 18 ( x = 3 ) .

Sales tax is calculated as a percentage of the sales price. If sales tax is 7%, what is the sales tax on clothing that costs $150?

Answers

Answer:

$160.50

Step-by-step explanation:

You multiply $150 by .15 to find out what 15% of it  (10.50)

You add the values to get $160.50

10.5 is  the sales tax on clothing that costs $150

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given that Sales tax is calculated as a percentage of the sales price.

sales tax is 7%

We need to find the the sales tax on clothing that costs $150

Convert 7% to the decimal value by dividing with 100.

7/100=0.07

Now multiply 0.07 with 150

0.07×150

Zero point zero seven times of one hundred and fifty.

10.5

Hence, 10.5 is  the sales tax on clothing that costs $150

The question is incomplete. Here is the complete question.

Quadrilateral EFGH is a scaled copy of quadrilateral ABCD. Select all of the true statements.

A. Segment EF is twice as long as segment AB.

B. Segment CD is twice as long as segment FG

C. The measure of angle HEF is twice the measure of angle DAB

D. The length of segment EH is 16 units.

E. The area of EFGH is twice the area of ABCD.

Answer: A. Segment EF is twice as long as segment AB

              D. The length of segment EH is 16 units

              E. The area of EFGH is twice the area of ABCD

Step-by-step explanation: One quadrilateral which is scaled copy of another quadrilateral means both quadrilateral are similar, i.e., they have congruent angles (same angles) but different sides lengths.

Comparing side GH with side CD, you notice GH's length is twice the side CD. This relationship between each corresponding sides is called scale factor.

Analysing statements above:

A. This statement is correct because segments EF and AB are corresponding sides, so EF will be twice as much as AB;

B. This is incorrect because they are not corresponding sides, so they are not related;

C. Is incorrect because measure of angle in similar quadrilateral has the exact same angle;

D. Statement is correct because if segment AD is 8 units, the corresponding segment EH will be:

EH = 2 x 8 = 16 units

E. Tis statement is correct because area of quadrilateral ABCD is proportional to the area of quadrilateral EFGH by the scale factor, therefore, area of EFGH is twice the area of ABCD.

Step-by-step explanation:

Given parameters:

The midpoint = ?

Solution:

 To find the midpoint of these endpoints;

   this can be mathematically expressed as;

  x[tex]_{m}[/tex] , y[tex]_{m}[/tex]  = [tex]\frac{x_{1} + x_{2} }{2} , \frac{y_{1}+y_{2} }{2}[/tex]

       x₂  =   -1                          y₂ = 4

x[tex]_{m}[/tex] , y[tex]_{m}[/tex] = [tex]\frac{5+(-1)}{2}[/tex]  ,  [tex]\frac{1 + 4}{2}[/tex]   = 2, [tex]\frac{5}{2}[/tex]

Find the equation of the line.

Y=__x + __

Answers

Answer:

y = 3x + 3

Step-by-step explanation:

Using slope intercept form: y = mx + b

where m is the slope(rise over run/change in y over change in x), and b is the y intercept(point where x is 0). We can derive the equation by simply using our mathmatical principles of slope and y intercept. Because our y intercept is where x is 0. Our y intercept is 3 since x is 0 when y is 3 because it touches the axis. Since y is 6 when x is one.

y = mx + b

6 = m(1) + 3

-3 -3

_________

3 = m

_________

m = 3

_________

An m of 3 means that you rise 3 every 1 run or 3y every 1x.

Therefore, our equation in slope intercept is:

y = 3x + 3

Michael earns $12.50 per hour. Which equation describes this statement?

y=25x
y=12x
y=0.5x
y=12.5x

Answers

Answer: y= 12.5x

Step-by-step explanation:

The last equation describes this statement because if he earns 12.50 per hour the y will be the amount he earns in x hours. For every hour, the money will go up by $12.50.

The answer would be y=12.5x. If they were to ask a question that included how many hours he worked and you were trying to figure out how much he made in those hours you would plug the number of hours into x and solve it.

Step-by-step explanation:

To determine x% of y, we must calculate x*y/100.

The number of campers that participated in Big Lake Camp during its first year was 40. We now want to know the number of campers that participated this year, if the attendance was 180% of the first year's.

The new attendance is calculated as follows:

40 * 180 / 100 = 72

72 campers participated this year

Find the equation of the line that is parallel to the given line and passes through the given point. y=-5x+7;(7,0)

Answers

Answer:

y = -5x + 35.

Step-by-step explanation:

y = -5x + 7

The slope for that y = -5x+7 is -5. Parallel lines have the same slopes which means the line parallel to that one will also have a slope of -5.

So now let's use the slope intercept form to create the equation that is parallel to the above equation.

y = mx + b

Since slope (m) is -5, we can plug it into the equation.

y = -5x + b

Now let's use the point (7,0) to find the y-intercept (b). We can do that by plugging the numbers in (7 for x and 0 for y).

y = -5x + b

0 = -5(7) + b

0 = -35 + b

b = 35

Now let's plug the y-intercept back into the equation.

y = -5x + 35

Therefore, the equation is y = -5x + 35.
