Answer:

2.5 hours

Step-by-step explanation:

20 ÷ 8 = 2.5

we have to divide the 20 by the 8 to figure out the amount of time and because Joey rode at 8 mph and traveled 20 miles than if you divide the miles traveled (y) by the rate (m), then you would get the amount of time it took (x); keep the slope intercept formula, y = mx + b, in mind

since there wasnt a y-intercept then you can ignore the b, but if you plug in the numbers for the variables then it would be right

20 = 8(2.5)

20 = 20

B) 2.5 hours , because 8 mph is 1 hour and the another 8mph is 1 hour 8+8mph =16mph 1+1hr=2hr half of 8 is 4mph is .5hr so therefore 8+8+4=20mph 1+1+ 30mins= 2.5hr

Nataliya [291]

Answer:

He should order 15 long boards

Question:

Escape park owner want 30% of each order to include long boards he wants to know how many long boards to order out of a total of 50 skateboards

Step-by-step explanation:

Let x and y represent the number of long board and the total number of skateboard to order.

Given that 30% of each order to include long boards;

x = 30% of y

x = 0.3y .....1

But, the total number of skateboard is given as 50

y = 50

From equation 1

x = 0.3y = 0.3(50)

x = 15

He should order 15 long boards

A baseball fan is seated in the upper deck of a stadium 200 feet away from

Mrac [35]

Please find attached to this answer a well labelled diagram of the triangle

Answer:

Approximately 176.6 feet

Step-by-step explanation:

From the question, we are to find the height at which the baseball fan was sitting.

From the attached diagram the height at which the fan was sitting is equivalent to the opposite side of the triangle.

Hence , the appropriate trigonometric function to use to solve this question is the sine function.

Sine = Opposite / Hypotenuse

Opposite is unknown so we refer to it as Y

Hypotenuse = 200feet

While the Angle of depression = 62°

Therefore,

Sine 62° = Y/ 200 feet

Cross multiply

Sine 62° × 200 feet = Y

Y = 176.58951857 feet

Approximately 176.6 feet

Therefore , the height at which the fan is sitting is 176.6 feet
