Juan jogs each day from his house to a local park, and then he jogs back along the same route. On his way to the park, he averages 4 miles per hour. On his way home, he averages 6 miles per hour. If the total trip takes 1 and one-half hours, which equation can be used to find x, the distance in miles from Juan’s house to the park? Distance (mi) Rate (mi/hr) Time (hr) Trip to Park x 4 mph Trip to Home x 6 mph StartFraction x Over 4 EndFraction + StartFraction x Over 6 EndFraction = 1 StartFraction x Over 4 EndFraction + StartFraction x Over 6 EndFraction = 1 and one-half 4 x + 6 x = 1 and one-half 4 x + 6 x = 1

Answers

Answer 1

Answer:

The distance traveled equals the speed v multiplied by the time t

Since the speed varies, and we only know the total time, we must rewrite this as:

If we separate this in the two 'directions', it should add up to one and a half:

That would lead me to answer b

A'Reana earns a weekly allowance for doing chores around the house and for keeping all of her grades above a C. During a particular week, she gave $10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50. How much is A'Reana's weekly allowance?

Answers

Given :

During a particular week, she gave $10 to her friend Taylor, spent half of the remaining money on a new shirt, and then spent $7.50 on a pizza. At this point, she had $37.50.

To Find :

How much is Reana's weekly allowance.

Solution :

Let, allowance is x.

Then by given conditions :

37.50 = x - ( 10 + x/2 + 7.50 )

37.50 = x/2 - 17.50

x/2 = 55

x = $110

Therefore, Reana's weekly allowance is $110.

Hence, this is the required solution.

Bobbie and Adam each own 35% of partnership BAB. On October 15, 2018, Bobbie sells her interest to Bob, who is a 30% partner. On October 16, 2019, Adam sells his interest to Bob. When does the partnership terminate?

Answers

Answer:

Step-by-step explanation:

Such partnerships only terminate when one of the partners sells his entire share which makes him no longer a partner in the company, but there may still be another partnership in the company. The other way all partnerships in the company terminate is when a single party/partner gains control of the entire companies' shares meaning they are 100% owner of the company and no other individual has any controlling interest in the company.

Different nerve signals travel at different speeds. Pressure and touch signals travel about 250 feet per second. Dull pain signals travel about 2 feet per second. How long does it take you to feel an ant crawling on your foot? Write your answer in a sentence using context. How much longer does it take to feel a dull ache in your foot? Write your answer in a sentence using context.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Pressure and touch signal speed = 250 feets per Second

Dull pain signal speed = 2 feets per second

Ant crawling on foot

A crawling ant on one's feet can be attributed to a touch signal, hence it will take ;

Time = Distance / speed

(Distance moved by crawling ant / 250)

(Dull ache in foot) = 250 / 2 = 125

It takes 125 times longer to feel a dull ache in foot.

Answers

B:7.5

Step-by-step explanation:

since 4 goes with 30, 6 goes with 45, and 8 goes with 60, you can see that 60-45 is 15 and 45-30 is 15 as well so the constant is 15, but the number of books is going up by two so the constant there is 2. So divide 15 by 2 and the answer would be C: 7.5.

During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.

Answers

Answer:

0.75 inches of snow

Step-by-step explanation:

During a winter storm, a ski resort received 9 inches of snow in 12 hours. The snow fell at a steady rate. How many inches of snow fell at each hour.

12 hours = 9 inches of snow

1 hour = x

Cross Multiply

12 hours × x = 1 hour × 9 inches

x = 9/12

x = 0.75 inches

Therefore, 0.75 inches of snow fell at each hour.

Answers

Answer: The diameter is two times the radius, so the equation for the circumference of a circle using the radius is two times pi times the radius. If you are given the circumference but not the radius or the diameter, you can still solve for one or the other using these formulas.

Step-by-step explanation:

The radius of the circle which has a circumference of the cirlce of 200π will be 100 feet.

What is the circumference of a circle?

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let r be the radius of the circle. The circumference of the circle will be

C = 2πr units

The circumference of the circle is given as 200π feet. Then the radius of the circle is given as,

200π = 2πr

Simplify the equation, then the value of the variable 'r' will be given as,

200π = 2πr

r = 100 feet

The radius of the circle which has a circumference of the cirlce of 200π will be 100 feet.
