It takes five days to repair 1250 meters of road. At this rate, how long will it take to repair 8 km of road?

Answers

Answer 1
32 days bcz 1250 meters took 120 hours (120 hrs=5 days) so 8000 m will take: 8000x120/1250= 768 hrs
782 hrs/24= 32 days
Answer 2

The number of days to repair 8 km of road is given by the equation A = 32 days

What is Proportion?

The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.

The proportional equation is given as y ∝ x

And , y = kx where k is the proportionality constant

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Given data ,

Let the number of days to repair 8 km be represented as A

Now , the proportion will be

Let the distance be = 1250 meters = 1.250 km

The number of days to repair 1.250 km is = 5 days

Substituting the values in the equation , we get

5 / 1.250 = A / 8

Multiply by 8 on both sides of the equation , we get

A = ( 8 x 5 ) / 1.25

A = 40 / 1.25

A = 32 days

Hence , the number of days is 32 days

What is the image point of (7,-7) after a translation of 3 right and 1 down followed by
a reflection over the x-axis?

Answers

Answer:

The image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

P''(10, 8)

Step-by-step explanation:

Given the point

(7, -7)

Translation of 3 right and 1 down means we need to add 3 units to the x-coordinate and subtract 1 unit from the y-coordinate

Therefore, the translation rule:

(x, y) → (x+3, y-1)

In our case, let the point P(7, -7)

P(7, -7)  → P'(7+3, -7-1) → P'(10, -8)

FOLLOWED BY A reflection over the x-axis

We know that the rule of reflection over the x-axis implies that

(x y) → (x, -y)

i.e. the x-coordinate of the point remains the same, but the y-coordinate changes its sign.

After the first transformation, we had got P'(10, -8)

so

P'(10, -8) → P''(10, -(-8)) → P''(10, 8)

Therefore, the image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

P''(10, 8)

The ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3.
If there are 48 paintbrushes, how many bottles of paint are there?

Answers

Answer:

Well, 48 divided by 8 is 6. And 6 times 3 is 18. So I belive that there would be 18 bottles of paint.

Step-by-step explanation:

The number of bottles of paintbrushes is 18.

What is a fraction?

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A ratio shows how often one number is contained in another.

For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

Given that the ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3. If there are 48 paintbrushes.

The number of the bottles will be calculated as:-

P / B = 8 / 3

3P = 8B

3 x 48 = 8B

B = 3 x 6

B = 18

Therefore, the number of bottles of paintbrushes is 18.

The angle of a quadrilateral are in the ratio 4:6:3 and it's fourth angle is 100. Find the other three angles of the quadrilateral

Answers

Step-by-step explanation:

Sum of angles in a quadrilateral = 360°

Sum of first 3 angles = 360° - 100° = 260°.

260° / (4 + 6 + 3) = 20°.

First angle = (20°) * 4 = 80°

Second angle = (20°) * 6 = 120°

Third angle = (20°) * 3 = 60°

The angles are 80°, 120° and 60°.

Answer:

Let the angles of the quadrilateral be 4x, 6x, and 3x

Sum of the interior angles of a quadrilateral is 360°.

According to the above problem,

[tex]4x + 6x + 3x + 100 = 360 \\ 13x = 360 - 100 \\ 13x = 260 \\ \boxed{x = 20}[/tex]

1st angle=4x=4×20=80°2nd angle=6x=6×20=120°3rd angle=3x=3×20=60°

Hence, the other three angles are 80°, 120° and 60°.

The unknown values of number for each of the expression is 8, 10, 3000, 1440, and 25.

What is Percentage?

A percentage is a portion of a whole number which is expressed as a number between the range of 0 and 100 rather than as a fraction. All of a thing is 100 percent, half of it is 50 percent, and none of something is zero percent. To determine a percentage, we divide the portion of the whole through the whole of itself and multiply it by 100.

x × 150/100 = 12

x = 12 × 100/ 150

x = 1200/ 150

x = 8

x × 50/100 = 5

x = 5 × 100/ 50

x = 500/ 50

x = 10

x × 10/100 = 300

x = 300 × 100/ 10

x = 30000/ 10

x = 3000

x × 5/ 100 = 72

x = 72 × 100/ 5

x = 7200/ 5

x = 1,440

x × 80/ 100 = 20

x = 20 × 100/ 80

x = 2000/ 80

x = 25

Therefore, the values of unknown numbers are 8, 10, 3000, 1440, and 25, respectively.

Find the distance along an ark on the surface of the earth that subtends a central angle of 10 minutes (1 minutes 1/60 degree) The radius of the earth is 3960 miles around to the thousands

Answers

Answer:

11.52 miles

Step-by-step explanation:

We know that the length of an arc L = Ф/360 × 2πR where Ф = angle subtended by arc and R = radius of circle.

Now since Ф = 10 minutes = 10 × 1 minute = 10 × (1/60)° = (1/6)° and R = radius of earth = 3960 miles

So  L = Ф/360 × 2πR

= (1/6)°/360 × 2π(3960 miles)

= 1/2160 × 7920π

= 3.67π

= 11.52 miles
