This is a division problem. we need to divide 40 inches by 8 3/4 inches.

40 / 8 3/4 =

= 40 / (35/4)

= 40 * 4/35

= 8 * 4/7

= 32/7

Natalie did 87 sit-ups in 3 minutes.

What is the unit rate?


At this rate, how many sit-ups can Natalie do in 5 minutes?

Answers

Answer:

19 sit-ups per minute ;

95 sit-ups

Step-by-step explanation:

Given that :

Number of sit-ups done in 3 minutes = 57

The unit rate of sit-ups done can be obtained thus :

Total Number of sit-ups done / total time taken

= 57 sit-ups /3 minutes

= 19 sit-ups per minute

. Number of sit-ups that can be done in 5 minutes :

Unit Rate of sit-ups * number of minutes

19 sit-ups / minute * 5 minutes

= 95 (sit-ups / minute * minute)

= 95 sit-ups

The angle of depression from a lifeguard in her chair to a person swimming in a pool is 38 degrees. If the height of the chair is 12 feet tall, find the distance from the base of the lifeguard's chair to the swimmer.

Answers

Answer:

15.36 feet

Step-by-step explanation:

We solve the above question using Trigonometric function of Tangent

Tan θ = Opposite /Adjacent

From the question

θ = 38°

Opposite = the height of the chair = 12 feet tall

Adjacent = the distance from the base of the lifeguard's chair to the swimmer = x

Hence:

tan 38° = 12/x

Cross Multiply

tan 38° × x = 12

x = 12/tan 38°

x = 15.359299586

x ≈ 15.36 feet

Hence, the distance from the base of the lifeguard's chair to the swimmer is 15.36 feet

Find the equation of the line that passes through (-1,2) and is perpendicular to 2y = 2x – 1.
Leave your answer in the form y = mx + c

Answers

Step-by-step explanation:

question is solved above in the picture

The equation of line that passes through point (-1,2) and which is perpendicular to 2y = 2x – 1 will be y = -x + 1.

Equation of line

The General equation of a line is ax + by + c = 0

How to solve this problem? Since the line is perpendicular to 2y=2x-1, this means that its slope with be the opposite reciprocal of the line 2y=2x-1 ‘s slope.First, we should find the slope of the line 2y=2x-1:

2y=2x-1

y=x-1/2

Therefore, the slope of 2y=2x-1 is 1 and the opposite reciprocal of 1 is -1 So far, we have this: y=-x+bTo find b (the y-intercept) we can plug the point (-1,2) into the equation we have so far and solve for b.

y=-x+b

2=-(-1)+b

2=1+b

b=1

So, the equation of the line that passes through (-1,2) and which is perpendicular to 2y=2x-1 is y=-x+b
