Y=21
Step-by-step explanation:
1 square yard = 36*36 = 1296 sq ins
So 120 square inches = 120 / 1296 = 0.0926 square yards
Answer: x < 3
Step-by-step explanation:
Let's solve your inequality step-by-step.
7x−9<12
Step 1: Add 9 to both sides.
7x−9+9<12+9 =7x<21
Step 2: Divide both sides by 7.
7x/7 < 21/7
Answer: x < 3
Answer: Daniel bought 3 apples and 7 bananas.
Step-by-step explanation:
Let x represent the number of apples that Daniel bought.
Let y represent the number of bananas that Daniel bought.
He bought a total of 10 apples and bananas altogether. This means that
x + y = 10
Daniel and his children went into a grocery store and he bought $10.15 worth of apples and bananas. Each apple costs $1.75 and each banana costs $0.70. This means that
1.75x + 0.7y = 10.15 - - - - - - - - - - - 1
Substituting x = 10 - y into equation 1, it becomes
1.75(10 - y) + 0.7y = 10.15
17.5 - 1.75y + 0.7y = 10.15
- 1.75y + 0.7y = 10.15 - 17.5
- 1.05y = - 7.35
y = - 7.35/- 1.05
y = 7
x = 10 - y = 10 - 7
x = 3
Answer:
30 units
Step-by-step explanation:
The volume is given by ...
V = Bh
Filling in the given numbers, we can find the area of the base (B) to be ...
840 = B(14)
840/14 = B = 60
The area of the base is given by the formula ...
B = (1/2)Pa
where P is the perimeter and a is the apothem. Filling in the numbers we know, we have ...
60 = (1/2)P(4)
30 = P . . . . . . divide by 2
The perimeter of the base is 30 units.
