Answer:
Penny:
3/100 ; 0.03
Dimes :
7/10 ; 0.7
Amount to add to make whole number = $0.23
Step-by-step explanation:
Recall:
100 pennies = $1
1 penny = 1 / 100
3 Pennies = 3 / 100 (In fraction)
3 pennies = 0.03
10 dime = $1
1 dime = 10 /100 = 1/ 10
7 dimes = 7/10 (fraction)
7 dimes = 0.7
To make the money in jar a whole dollar :
Amount to be added :
1 - (0.03 + 0.70)
1 - 0.73
= $0.27

Answer:
7
Step-by-step explanation:
AB//CD (Opposite sides of parallelogram are parallel)
Angle A + Angle B = 180 (Sum of interior angles=180)
138 + 7x - 7 = 180
7x - 7 = 180 - 138
7x = 42 + 7
7x = 49
x = 49/7
x = 7
To find how much paper for the model, you will use the formula for area of a square and area of a triangle.
A = bh
7.2 x 7.2
A = 51.84 cm²
A = 1/2bh
1/2 x 7.2 x 6
A = 21.6 cm²
21.6 cm² x 4 = 86.4 cm²
86.4 + 51.86=138.3
You will need 138.3 cm² of paper.
