A community group is picking up trash along a portion of the highway that is 1.48 miles long. In one hour they can clean a section about 1/8 mile long. Approximately how many hours will it take the group to clean the stretch of highway?
Please help ASAP
The answers are
3/16
16/3
2
12

Answers

Answer 1

Answer:

12 if im correct

Step-by-step explanation:

first we have to see that they are doing 1/8 of a mile per hour so if we divide 1.48 by 1/8 it should give us the time

first we convert 1/8 to a decimal which is .125 and we divide 1.48 by .125

giving us 11.84

since it is time, 11 hrs would be too little of a time so we need to round up to 12

Hope thats right

Answer 2

The number of hours for the group to clean the stretch of highway is A = 12 hours

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

In an equation, the expressions on either side of the equals sign are called the left-hand side (LHS) and the right-hand side (RHS), respectively. The equals sign (=) indicates that the two expressions have the same value, and that the equation is true for certain values of the variables involved.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. It typically consists  mathematical operations, such as addition, subtraction, multiplication, division, and exponentiation.

Given data ,

Let the number of hours be represented as A

Now , the value of A is

If the group can clean 1/8 mile of the highway in one hour, we can calculate how many sections of 1/8 mile are in 1.48 miles:

1.48 miles / (1/8 mile per section) = 11.84 sections

On simplifying the equation , we get

This means that the group will need to clean 11.84 sections of 1/8 mile each to clean the entire stretch of highway.

Since they can clean 1 section in 1 hour, it will take them 11.84 hours to clean the entire stretch of highway ≈ 12 hours

Hence , the number of hours to clean the highway is 12 hours

5 ( f + 4) = 4 ( f - 6)

Answers

f = -44

Hope this helps :)

Answer:

The answer is -44

Step-by-step explanation:

First, you use distributive property on each side.

5xf + 5x4 = 4xf-4x6

5f+20=4f-24

Then you subttract 5f to both sides of the equation.

5f+20=4f-24

-5f       -5f

20=-1f-24

Next, you add 24 to both sides of the equation.

 20=-1f-24

+24     +24

44=-1f

Finally, you divide -1f from each side of the equation.

44=-1f

/-1f   /-1f

Your final answer should be -44=f

or f = -44

The ratio of balls to tennis balls is 4:7 is a correct statement; however, we need to check the other questions for reliablity.

For every 6 basketballs, there are 10 dodge balls is a wrong statement because the number of basketballs is 12 and the number of dodge balls is 18 not 20. So, this answer is wrong.

None of the above is wrong because the first answer is correct so we can cross out c.

Now we know that A is the correct answer!

It is A, the ratio of soccer balls to tennis balls is 4:7.

Soccer Balls : 8

Tennis balls: 14

8 divided by 2 is 4 and 14 divided by 2 is 7.

4:7

B is not right because

Basketball: 12

Dodgeball: 18

"For every 6 basketballs, there are 10 dodge balls."

12 divided by 2 is 6

If it was 10 dodge balls for every 6, dodge balls would be 20 because there are 2 6s in a 12.

And it can't be C, none of the above because A is correct.

So yea it's A.

A linear function can be used to estimate the decrease in snowfall measured since 1920. The decrease in the annual snowfall has been on average 0.24 inches per year. Let x represent the number of years since 1920, when the measurements began, and let y represent the annual snowfall. The initial measurement in 1920 was 48.6 inches. Using the average change and initial measurement, which is the best estimate of the annual snowfall in the 78th year after records were kept? Round to the nearest hundredth.

Answers

Answer:

29.88 inches

Step-by-step explanation:

Equation of a line is given in the form  

Where

m is the slope [rate of change, here, rate of decrease]

c is the y-intercept [at 1920, the snowfall]

From the problem, we see that snowfall decreases by 0.24 inches per year, that will make the slope (m) to be -0.24

Also, at 1920, the initial measurement was 48.6 inches of snow, that is the y-intercept (b). Thus, we can write the equation of this line as:

y = mx + b

y = -0.24 x +48.6

To find annual snowfall, 78th year after 1920, we simply plug in 78 into "x" of the equation just found. So:

y = -0.24(78) + 48.6 = 29.88 inches

29.88 inches

A cylinder has a volume of 1884cm^3. Find the volume of a cone with the same radius and height as the cylinder

Answers

Answer:

628

Step-by-step explanation:

The volume V of a cylinder whose radius is r and height is h is given as

V = πr²h

The volume of a cone v of a radius r and height h is also given as

v = 1/3 πr²h

As such , given that the cylinder has a volume of 1,884 cm ³, the volume of a cone with the same radius and height as the cylinder

= 1/3 * 1,884 cm ³

= 628 cm ³

i think it is 628 so tell me if i’m correct :)
