F=Friday
S=Saturday
P(F or S)= 20/90+22/90-20/90=22/90
22/90 as percentage is 24.44 percent
Answer:
For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.
Step-by-step explanation:
Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.

The cone and cylinder above have the same radius and height. The volume of the cone is 162 cubic inches. What is the volume of the cylinder?
A. 54 cubic inches
B. 81 cubic inches
C. 324 cubic inches
D. 486 cubic inches
The volume of the cylinder is 486 cubic inches.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
Given that,
Radius and height of the cylinder and the cone are same.
Let r and h be the radius and height of each of the cylinder and the cone.
Volume of the Cone = [tex]\frac{1}{3}[/tex] π r² h
Volume of the cylinder = π r² h
We have, volume of the cone is 162 cubic inches.
[tex]\frac{1}{3}[/tex] π r² h = 162
Multiplying both sides by 3,
π r² h = 162 × 3
π r² h = 486 cubic inches
Hence the volume of the cylinder is 486 cubic inches.

If F(x) = x² + 5x and G(x) = 2x + 1, find F(5) + G(6). 48 63 107
Answer:
63
Step-by-step explanation:
F(x) = x² + 5x
F(5) = (5)² + 5(5) = 25 + 25 = 50
G(x) = 2x + 1
G(6) = 2(6) + 1 = 12 + 1 = 13
F(5) + G(6) = 50 + 13 = 63

Find the area of the square pyramid represented by this net.
Answer:
16cm
Step-by-step explanation:
Erik transformed the equation y = 2(x − 2)^2 + 5 from vertex form to standard form. His steps are shown below. Is Erik's work correct? If not, identify and correct his error.
y = 2(x − 2)^2 + 5
y = 2(x^2 − 4x + 4) + 5
y = 2x^2 − 8x + 8 + 5
y = 2x^2 − 8x + 13
A. No. The error is in the second line: the expanded form of (x − 2)^2 is x^2 − 4.
B. No. The error is in the third line: the product of 2 and x^2 − 4x + 4 is 2x^2 − 4x + 4.
C. No. The error is in the fourth line: the sum of 8 and 5 is 12.
D. Yes. Erik is correct in his transformation from vertex form to standard form.

Answer:
1/16
Step-by-step explanation:
The equation of a direct proportion is
y = kx
Let amount of fertilizer = y and amount of peat moss = x
We have x = 12 when y = 3/4
3/4 = k * 12
k = (3/4)/12 = 3/4 * 1/12 = 3/48 = 1/16
y = 1/16 x
The constant of proportionality is 1/16.
