In drawings, a rectangular shape can be enlarged or compressed using scale ratios

<h3>The perimeter of the drawing</h3>

The dimensions of the drawing are 4 in by 5 in

So, the perimeter is:

P = 2 * (4 in + 5 in)

This gives

P = 18 in

Hence, the perimeter of the drawing is 18 inches

<h3>The perimeter of the actual flower bed</h3>

The dimensions of the actual flower bed is 30 times greater than the drawing.

So, the perimeter is:

P = (30 + 1) * 18 in

This gives

P = 558 in

Hence, the perimeter of the actual flower bed is 558 inches

<h3>The effect on the perimeter</h3>

When the dimensions are multiplied by 24, the perimeter of the flower bed increases by a product of 24

Pachacha [2.7K]

Answer: OPTION C.

Step-by-step explanation:

1. To solve this problem you must apply the Pythagorean Theorem, which is shown below:

$a^{2}=b^{2}+c^{2}$

Where a is the hypotenuse, and b and c are the legs of the triangle.

2. When you solve for one of the legs and substitute values, you obtain that the result is:

$b=\sqrt{a^{2}-c^{2}}\\b=\sqrt{(24.8ft)^{2}-(8ft)^{2}}\\b=23.5ft$

Marco can finish a jigsaw puzzle in 3 hours. Working together with Cliff, it takes them 1 hour. How

vovikov84 [41]

Macro can finish the puzzle in 3 hours. We can say that her speed for working is 1/3 or 1/3 puzzle per hour.

Now if they work together, this turns into 1 puzzle per hour.

That must mean that Cliff would be doing the other 2/3 of the puzzle while Macro does his 1/3 in that hour. If Cliff has a speed of doing them 2/3 per hour. Then it would take 1 and a half hour to finish 1 whole puzzle.

Cameron buys 2.45 pounds of apples and 1.65 pounds of pears. Apples and pears each cost c dollars per pound. If the total cost a

nordsb [41]

Answer:

$4.12=2.45c+1.65c$

Step-by-step explanation:

We are given,

Cameron buys 2.45 pounds of apple and 1.65 pounds of pears.

Also, the cost of apples and pears is 'c' dollars per pound.

Thus, the cost of 2.45 pounds of apple is $2.45c$ dollars and the cost of 1.65 pounds of pear is $1.65c$ dollars.

Since, the total cost after using a coupon is $4.12.

So, we get the equation representing the situation is,

Total cost = Total cost of apples + Total cost of pears.

i.e. $4.12=2.45c+1.65c$

i.e. $4.12=4.1c$

i.e. $c=\frac{4.12}{4.1}$

i.e. c = 1 dollar

Hence, the required equation to find c is $4.12=2.45c+1.65c$ .
