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.

A circle has circumference 200 pi feet.
What is the radius of the circle?

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.

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.

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.

Thurman put $90 into an account that pays 4.4% interest, compounded quarterly. According to the rule of 72, approximately how long will it take for his money to double?

Answers

Answer:

Number of Years to Double= 15.65

Step-by-step explanation:

Giving the following information:

Interest rate= 0.044/4= 0.011

Annual compound interet rate= (1.011^4) - 1= 0.4473

The rule of 72 is a means of estimating the number of years it takes for an investment or your money to double.

Round the numbers to estimate the quotient. 29 and one-fifth divided by 4 and StartFraction 6 over 7 EndFraction Which numbers should be used? 25 ÷ 5 The estimated quotient is

Answers

Answer:

The quotient is 6.

Step-by-step explanation:

Given two fractions are:

[tex]29\dfrac{1}{5}[/tex]

and

[tex]4\dfrac{6}7[/tex]

To find:

The quotient of

[tex]29\dfrac{1}{5}\div 4\dfrac{6}7[/tex]

Solution:

Formula to convert mixed fraction to a fraction:

[tex]p\dfrac{q}{r} = \dfrac{p\times r+q}{r}[/tex]

Using the above formula to rewrite the given mixed fractions:

[tex]29\dfrac{1}{5}[/tex] can be written as:

[tex]\dfrac{29\times 5+1}5\\\Rightarrow \dfrac{146}{5}[/tex]

[tex]4\dfrac{6}7[/tex] can be written as:

[tex]\dfrac{4\times 7+6}{7}\\\Rightarrow \dfrac{34}{7}[/tex]

Now dividing:

[tex]\dfrac{\frac{146}{5}}{\frac{34}{7}}\\\Rightarrow \dfrac{146\times 7}{5\times 34}\\\Rightarrow \approx 6[/tex]

Therefore the quotient is 6.

y = 22.627

tan(45) = 16/x

x = 16/tan(45)

x = 16
