Answer:
$150
Step-by-step explanation:
Additional 5% and 20% on the original cost is additional 25%
Total cost = 125% of 120
= (125/100)×120
= 150
Answer:
steps attached below
Step-by-step explanation:
You need the geometric means for right triangles. There are 3 different forms of it that help us solve for either leg, or the altitude. We are looking for how the altitude is related to the hypotenuse that is split in 2. For us that will look like this:
. Your answer is "s", second choice down.
Answer:
9.42 cubic inches
Step-by-step explanation:
We are to find the volume of the cone.
The formula is given as:
1/3πr²h
From the question,
Diameter = 3 inches, Radius = D/2 = 3/2
r = 1.5 inches
h = 4 inches
Hence, the volume of the cone =
1/3 × π × 1.5² × 4
= 9.42 cubic inches
Therefore, the filter can hold 9.42 cubic inches of liquid without overflowing.
Answer:
1200 > 42x+400
Step-by-step explanation:
We need to determine the equation of the line for the number of lilac bushes versus area
m = (y2-y1)/(x2-x1)
= (484-442)/(2-1)
= 42/1
= 42 square ft per lilac bush
Using point slope form of a line
y-y1 = m(x-x1)
y-442 = 42(x-1)
Distribute
y-442 =42x-42
Add 442 to each side
y-442+442 = 42x-42+442
y = 42x+400
This is the equation of the line
Ryan has less than 1200 square feet so our equation must be less than 1200 square feet
1200 > 42x+400
