what is one fifth of 200?​

Answer & Step-by-step explanation:

So if 14% are over 65, and 320 residents are over 65, then we can say that 14% of the town is 320. Then, we can divide by 14 to find 1%, which is 22.857142857 Now we can multiply this by 100 to get 2285.7142857, which is the answer. To double check, you'd just find 14% of 2285.7142857 (multiply by 0.14) which is equal to 320. Because you can't have fractions of people, however, you'd have to round the answer up to 2286 people.

If that is too difficult to understand them hope this is easier

14% of the towns population is 320. Let P denote the towns population.

14/100 * P =320

14P/100 = 320

14P = 32000

divide both sides by 14

P = 2285.71

the towns population is 2286

Hope this helps!

Answer:

520

Step-by-step explanation:

When rounding to the nearest ten, like I did with 524 above, we use the following rules:

A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.

B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.

C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

Answer: 2 1/2 cups of flour  will make 1 Loaf of bread.

Step-by-step explanation:

3 loafs of bread can be made from  71/2 cups of flour

1 Loaf of  bread  will require = x cups of flour

By cross multiplication , we have

(1 Loaf of  bread x 71/2 cups of flour) = 3 loafs of bread X x cups of flour

x cups of flour = (1 Loaf of  bread x 71/2 cups of flour)/ 3 loafs of bread

=15/2 X 1/3 = 5/2 = 2 1/2

OR  

7.5 /3  =2.5 = 2 1/2 cups of flour

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

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

(0,4) , (1,7) , (2,10) and (-1,1)

Step-by-step explanation:

Since you did not supply a graph, maybe I could give you some points that you should find the line on the correct graph goes through.

y = 3(0) + 4

y = 4

y = 3(1) + 4

y = 7

y = 3(2) + 4

y = 10

y = 3(-1) + 4

y = 1

The points (0,4) , (1,7) , (2,10) and (-1,1) should be on the line of the correct graph. In general, your graph should be of a straight line that crosses the y-axis at 4.

yes....i guess the rectangle is similar because both the side length of the rectangle have the same scale factor..

Picture 2:( x-4)²+(y-1)²=25

Step-by-step explanation:

Use the rule: ( x-p)²+(y-q)² =r

( p,q)is the coordinate of the center of the circle

r is the radius of the circle

Answer:

A = 153.94 sq mi

Step-by-step explanation:

In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following

A = [tex]\pi r^{2}[/tex]

A = [tex]\pi 7^{2}[/tex]

A = [tex]\pi 49[/tex]

A = 153.94 sq mi

A total of 153.94 square miles must be searched.

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]

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

Answer:

0.9968

Step-by-step explanation:

Given that:

P of being correct = 0.5 (since there are only 2 options in each question with only one bring correct).

1 - p = 1 - 0.5 = 0.5

Number of questions, n = 12

Probability that atleast 2 questions are correct

P(x ≥ 2) = p(x = 2) + p(x = 3) +... + p(x = 12)

P(x =x) = nCx * p^x * (1 - p)^(n - x)

The sun of the individual probabilities gives us the answer or we could use the binomial probability calculator :

Hence,

P(x ≥ 2) = 0.9968

Answer:

100 years

Step-by-step explanation:

Simple interest means 4% on the 20$ only and forever.

100-20=80 dollars.

4% of 20 is 0.80

80/0.80 = 100

It will take 100 years

Answer:

It takes 41 years for $20 to grow to $99.86 and if you rounded that up, it would be $100 or if you want it to surpass $100 it would take 42 years turning $20 to $103.85
