Abigail redecorates her house. A scale drawing of her house can be seen below. If each 6 cm on the scale drawing equals 12 ft, what are the actual dimensions of Abigail's house. The scale numbers are 10 cm, 9 cm, 8 cm, 9 cm, and 7 cm.

Answers

Answer 1

Answer: 6 cm = 12 ft * I noticed that the scale drawing is 1/2 of the actual dimension of Abigail's house.
So, every scale must be multiplied by 2 to get the actual dimensions.

10 cm = 20 ft
  9 cm = 18 ft
  8 cm = 16 ft
  9 cm = 18 ft
  7 cm = 14 ft

A bag contains 42 cups of dog food. Your dog eats 2 1/3cups of dog food each day. Is there enough food to last 3 weeks?

Answers

Answer:

it will last 18 days

Step-by-step explanation:

divide 42 by 2 1/3

2 1/3 = 7/3

42 / 7/3 =

42 * 3/7 =

126/7 = 18

if this isn't enough then here

The number of days it will take the dog to consume the 42 cup of food will be 18 days.

Total cups of dog food = 42 cups

Amount of cups consumed per day =

To obtain the number of days it will take to consume the entire food :

Divide the total amount of food by the amount consumed per day

Hence,

(42 ÷ (7/3))

Take the reciprocal of 7/3 and change the operation sign to multiplication

42 × 3/7 = (42 × 3) / 7 = 126 / 7 = 18 days

Therefore, it will take the dog 18 days to finish up the 42 cups of food.

Ron bought 8 pencils and 2 erasers for $1.66. Sarah bought 12 pencils and 5 erasers for $3.19. What is the cost for 1 pencil and 1 eraser?

Answers

p=price of 1 pencil
e=price of 1 eraser

1.66=8p+2e
divide by 2 for simplification
0.83=4p+e

3.19=12p+5e

0.83=4p+e
multiply by -5 and add to obht eration

-4.15=-20p-5e
3.19=12p+5e +
-0.96=-8p

divide by -8
0.12=p
sub back

0.83=4p+e
0.83=4(0.12)+e
0.83=0.48+e
minus 0.48 both sides
0.35=e

1e+1p=0.12+0.35=0.47

cosst is $0.47

A square painting has a diagonal of 44 in. Lorraine wants to frame the picture. How many inches of frame will she need? Round to the nearest inch.

Answers

The square has a diagonal of 44 inches.
In order to get the side, we need to use the pythagorean equation.

Diagonal (d) ^ 2 = side^2 + side ^ 2
Diagonal (d) ^ 2 = 2side (s)^2

d^2 = 2s^2
44^2 = 2s^2
1936 = 2s^2
2s^2 = 1936
s^2 = 968
s = 31.11 inches

The length of the side is approximately 31 inches.
Perimeter = 4*s
Perimeter = 4 * 31
Perimeter = 124 inches

So she need a total of 124 inches to frame the square.

I am sure the anwser is 124in

I hope this helps let me know! ;)
