Answer:

b)in order to do that you have to write out your problem using a proportional relationship. you start with picking out your scale factor and then you use that to calculate your enlargement. lets say your scale factor is 3:1.

3/1=x/21 x=63

c) 5/1=x/21 x=105       the appx. area of the park in the enlarged drawing will be 105ft sq

d)I identified the scale factor in each problem and then applied it to each of the separate situations in order to enlarge or reduce an amount/ image.

Step-by-step explanation:

The approximate area of the park of the park in your enlarged drawing is given by A = 105 inches²

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 proportion be represented as A

Now , the value of A is

The area of the map = 21 inches²

And , the scale factor of proportion is 5 : 1

So , the area of the drawing is given by

A / 21 = 5 / 1

Multiply by 21 on both sides , we get

A = 105 inches²

Therefore , the value of A is 105 inches²

Hence , the area of the drawing is 105 inches²

Answer: A.

Step-by-step explanation:

I did the test and got it correct.

Answer:

the answer is not A. the correct answer is D. 0.00000078

Step-by-step explanation:

The reason D.

is correct is because if you multiply 10 six times you will get 1,000,000

and all you have to do is take the zeros from 1,000,000 and add it to 0.78 you will get your answer.

(hope this helps)

Answer:

90sqft

Step-by-step explanation:

We have the base and the height, so we just compute

A = bh/2

A = 12ft * 15ft / 2 = 180sqft / 2 = 90sqft

Answer:

62.5

Step-by-step explanation:

Finally, we need to subtract the area of the triangle from the area of the rectangle to find the area of the banner: Area of banner = Area of rectangle - Area of triangle Area of banner = 70 - 7.5 Area of banner = 62.5 square inches So, the area of the banner is 62.5 square inches.

Answer:

(-3, -7)

Step-by-step explanation:

y = 4x + 5

y = x - 4

add 4 to both sides of the second equation to get y + 4 = x

plug that back into the equation to get y = 4(y + 4) +5

distribute to get y = 4y + 16 + 5

combine like terms y = 4y + 21

subtract 4y on both sides to get -3y = 21

divide both sides by -3 to get y = -7

plug -7 into the second equation to get -7 = x - 4

add 4 on both sides to get -3 = x

therefore (-3, -7)

Answer:

The area of the park is 119,966.14 cm if needed to round it would be 119,966 cm.

Step-by-step explanation:

first we would use A=length x width

so a = 614 cm x 212 cm = 130,168 cm

now we find the area of the pond using a= pi x r^2

the diameter is 114 cm so we cut that in half to find the radius which is 57 cm

a = pi x 57^2

a= 3.14 x 3249

a= 10201.86 cm

now we subtract the area of the pond from the whole area

130,168 - 10201.86 = 119,966.14 cm

The area of the park is 119,966.14 cm if needed to round it would be 119,966 cm

The area of the park on the map is 641.37 square yards.

To find the area of the park on the map, we need to first find the actual dimensions of the park in yards, and then calculate the area.

It is given that :

Scale on the map: 114 cm : 8 yards

Width of the park on the map: 212 cm

Length of the park on map: 614 cm

Diameter of the circular pond on the map: 114 cm

We know that, 1 yard = 114cm/8 = 14.25 cm

Therefore, the width of the park in yards = 14.91 yards.

Area of rectangle: Width x Length

Thus, Area of park = 14.91 yards x 43.09 yards

                               = 641.37 yards

Therefore the area of the park on the map is approximately 641.37 square yards.

Step-by-step explanation:

Answer:

i think you are mistaken. it would have to be "what two numbers when multiplied equal -12 and when added equal 4"

if that's the case then the answer would be -2 and 6

Step-by-step explanation:

-2*6=-12

-2+4=4

Answer:

its not possible because if we say 2: 2 + 2 is 4 and 2 x 6 is 12 it would have to be two numbers that both add up to 4 and multiply to 12

Step-by-step explanation:

2 + 2 = 4

2 x 6 = 12
