1. 70 dimes and 33 quarters
2. 18 dimes and 9 nickels
3. 236 adults and 342 children
4. 12 quarters, 9 dimes
5. 9 nickels, 18 dimes
The kite area can be calculated using the formula
a = 1/2 × d₁ × d₂
with d₁ as first diagonal and d₂ as second diagonal
From the question, we know that
d₁ = 9.5 + 9.5
d₁ = 19 in
d₂ = 7 + 12
d₂ = 19 in
Calculate the area by plugging in the numbers into the formula
a = 1/2 × d₁ × d₂
a = 1/2 × 19 × 19
a = 1/2 × 361
a = 180.5
The area of the kite is 180.5 in²
The answer is fourth answer
5 1/9 rounds to 5
1 7/8 rounds to 2
5+2 = 7
11/20 rounds to 1
5/8 rounds to 1
1-1 = 0
8/9 rounds to 1
2 13/15 rounds to 3
1+3 = 4
opposite angles are equal
so <B = <D = 145
Answer
B. 145
