How can I use a scale to help me find the actual perimeter of an object if I already know the perimeter of the scale drawing?

Answer:

Lets say you have a scale of 2 actual feet is equal to 1 graph inch. And lets say you have a perimeter of 24 inches. You know that for every inch I have graphed, it's an actual 2 feet. So if you multiply those 24 inches by 2, then you will get 48. And you need to change the units to match the description, so I will need to change inches to feet. This will get me 48 feet of perimeter in real life.

Answer:

186.5 + 2x

Step-by-step explanation:

First, radify 25. Luckily it's a perfect square so it will be 5.

Second, divide within the parentheses. You're expression should look like this.

(93-5+x+42/8)2

Divide 42/8. The decimal form would be 5.25, while the fraction should be 5 1/4.

Third, solve within the parentheses from left to right. Right now you're expression should look like this:

(93-5+x+5.25)2

Add all like terms

93-5+5.25=93.25

Fourth, multiply. Right now the expression should look like this:

(93.25 + x) 2

186.5 + 2x

Shelly and Mickelle are making a quilt. They have a piece of fabric that measures 48 inches by 168 inches.
irinina [24]

Answer:

(a) The largest square side is 24 inches

(b) No. of pieces are 14

Step-by-step explanation:

As per the question:

The dimensions of the fabric are 48 in\times 168 in

(a)To calculate the side length of the largest square piece, we need to find the Greatest Common Factor (GCF) of the dimensions as:

48 = 2\times 2\times 2\times 2\times 3

168 = 2\times 2\times 2\times 3\times 7

Therefore,

The GCF of the dimensions = 48 = 2\times 2\times 2\times 3 = 24

Therefore, the largest side of  a square that can be cut from the fabric is 24 inches.

(b) The no. of pieces of 24 inches that can be cut from the fabric can be given as:

No. of pieces = \frac{Total\ Area}{Area\ of\ largest\ square}

No. of pieces = \frac{48\times 168}{24\times 24} =  14

Step-by-step explanation:

So this is an isosceles triangle so the other angle must be x too.

2x+40 = 180

2x = 140

x = 70

1. Use formula provided

2. A = 3500 B = 2000 r = 4.75 n = 12months/4 = 3 months t = ?

3. Solve

3500=2000(1+4.75/3)^3t

3t=logbase(31/12)*1500

t=logbase(31/12)*1500 / 3

t ≅2.568
