Answer:
Step-by-step explanation:
Area of circle = πr²
= 3.14 * 12 * 12
= 452.16 sq. cm
4y-6y+9y=-2
Answer:
4y-6y+9y=-2
-2y+9y=-2
7y=-2
therefore divide 7 on both sides
7y/7=-2/7
y=-2/7
y=-0.2857
Answer:
Step-by-step explanation:
We know that represents the total number of eggs and represents the number of chickens.
According to the problem, this magnitudes are proportional that means
Where represents the constant of proportionality.
However, the problem states that each chicken laid the same number of eggs, 4. This means, the constant of proportionality is 4, that is .
Therefore, the equation that could be used to the total number of eggs collected from the cop is
In words, the total number of eggs collected is 4 per chicken.
A) 72°
B) 108°
C) 144°
D) 216°
inches and a height of 20 inches. Players use conical
paper cups, as shown below.
If the water cooler is filled completely, can each of the
38 players have two full paper cups of water during
practice? Explain
4.4 in.
O No, because there is enough water in the cooler for
about 3 cups total.
No, because there is enough water in the cooler for
about 59 cups total
5.5 in.
Yes, because there is enough water in the cooler
for about 81 cups total.
Yes, because there is enough water in the cooler
for about 2,261 cups total.
The radius and height of the cooler of 6 and 20 inches respectively, can
contain approximately only 81 cups, the correct option is therefore;
The dimensions of the cooler are;
Radius = 6 inches
Height = 20 inches
The possible dimensions of a cup are;
Diameter = 4.4 inches
Height = 5.5 inches
Required:
If each of the 38 players have 2 paper cups filled with water.
Solution;
The volume of the cooler, V₁, is found as follows;
V₁ = π × 6² × 20 = 720·π
The volume of the cooler, V₁ = 720·π in.³
The volume of the paper cup, V₂, is;
The volume of the paper cup, V₂ = in.³
The number of cups, n, in the cooler of water is therefore;
The number of cups of water in the cooler ≈ 81 cups
The number of cups required for each of the 38 player to have two full cups is, Cups = 38 × 2 = 76 cups
Given that the water available, (approximately 81 cups) is more than the
number of cups required (76 cups), the correct option is option;

Answer:
The third option (C) Yes, because there is enough water in the cooler for about 81 cups total.Step-by-step explanation:
