The average time taken by workers to complete the repairing of the road is about the 4 and half weeks.

According to the statement

We have to find that the Time taken by the workers.

So, For this purpose, we know that the

Average time is a measurement that evaluates how long a works spends on repairing roads.

From the given information:

A 13 km stretch of road needs repairs. Workers can repair 3 km of road per week.

Then

If worker complete 3 km of the road in the 7 days

Then

Workers complete 13 km in the days = Total distance / Average distance

Then

Workers complete 13 km in the days = 13 / 3

Workers complete 13 km in the days = 4.33 weeks.

Answer:

32°

Step-by-step explanation:

Angles 2 and 4 are vertical angles, so they are congruent. That means that their measures are equal.

First, we set their measures equal to each other.

Then we solve the equation for x.

Then, we use the value of x to find the angle measure.

m<2 = 6x + 5

m<4 = 4x + 14

Set the measures equal.

6x + 5 = 4x + 14

Subtract 4x from both sides.

2x + 5 = 14

Subtract 5 from both sides.

2x = 9

Divide both sides by 2.

x = 4.5

m<2 = 6x + 5

m<2 = 6 × 4.5 + 5

m<2 = 27 + 5

m<2 = 32

Answer: 32°

Answer:In the number, 687,760, there are two 7s; one is at a place value of hundred and the other is at thousand.

Hence, the higher place value 7 is 10 times greater than lower place value 7. Every consecutive place value is 10 times greater than the right one.

Let x represent the investment in A and y represent the investment in B.

Total investment is $75,000 ( given )

hence x + y=$75,000 (from the above information)

x + y= 75,000     (equation 1)

Interest rate in A is 4.5 % and Interest rate in B is 3 %

now, 4% of $75000 = $3000

Charlie 50 miles per hour

Violet 60 miles per hour

It is given that the distance between Memphis and New Orleans is 395 miles. This means, the total distance both covered = 395 miles

Charlie drove for 5.5 hours and Violet drove for 2 hours. Let the speed of Charlie be x miles per hour. Since, the speed of Violet was 10 miles per hour faster than Charlies, the speed of charlie was (x + 10) miles per hour

Since, distance = speed × time

Distance covered by Charlie = 5.5x

Distance covered by Violet = 2(x + 10)

Altogether they covered 395 miles,

So,

395 = Distance covered by Charlie + Distance covered by Violet

395 = 5.5x + 2(x + 10)

395 = 5.5x + 2x + 20

375 = 7.5x

x = 375/7.5

x = 50 mph

Since, x represents the speed of Charlie, the speed of charlie was 50 miles per hour and speed of Violet =

The depreciation for the first year of the truck's useful life is $32,000.

The cost of the truck is $40000.

The useful time is 5 years.

The residual value is $5000.

Now, the depreciation is given as:

SLM depreciation = (Cost - Residual Value) / 5 years

Depreciation expense per year = ($40,000 - $5,000) / 5

Depreciation expense for the first year = $7,000

Now,

The depreciation expense per mile is the difference between cost and residual value divided by expected miles over the truck's life.

Depreciation expense per mile = (Cost - Residual Value) / Expected miles over truck's life.

Depreciation expense = Depreciation expense per mile × Miles driven

Therefore,

Depreciation expense per mile will be:

= ($40,000 - $5,000) / 15,000 miles = $2.33 or $2

The slope of the line is given as m = - 3 / 5.

The pair of point are (r, 7)(3, 4).

Using slope intercept form equation is as follows:

y = mx + b

where

Therefore, using (3, 4) we will find the y-intercept

y = - 3 / 5 x + b

4 = -3  / 5 (3) + b

4 = - 9 / 5 + b

b = 4 + 9 / 5

b = 20 + 9/ 5

b = 29 / 5

Therefore, the equation of the line is as follows;

y = - 3 / 5x + 29 / 5

Hence, let's find r (r, 7)

7 = -3 / 5(r) + 29 / 5

7 - 29 / 5 = -3 / 5 r

35 - 29/ 5 =  -3 / 5 r

6 / 5 = - 3 / 5 r

2 (9/14)

Step-by-step explanation:

The x-intercepts and y-intercepts (9,0) and (0,7) respectively.

In geometry, a line draw in between the coordinate axes by using the intercepts. The intercepts are the intersecting points of the points of the line with coordinate axes. The intersecting point of the line with x - axis is called the x - intercept (a,0). Here a is the intercept length.

Similarly,  The intersecting point of the line with y - axis is called the y - intercept (0,b). Here b is the intercept length.
