Answer:
$65
Step-by-step explanation:
x is the number of items sold, and y is the profit, so we need to calculate
y = 35x - 250
where x=9
y = 35*9 - 250 = 315 - 250 = 65
So the total profit is 65 dollars

A cylinder has a volume of 200in^3. Determine the volume of a cone whose radius and height are equal to that of the cylinder
Answer:
66.67 in^3
Step-by-step explanation:
volume of a cylinder = nr^2h
Volume of a cone = 1/3(nr^2h)
n = 22/7
r = radius
the volume of a cone is 1/3 that of a cylinder
volume of the cone = 1/3 x (200) = 66.67 in^3
Malik got a 200 cafe gift on January 1. He always orders decaf mochas which cost 5 each. At the end of January, maliks gift card has 125 left. Write an equation with x as your variable.
Answer:
200 - 5x = 125
Step-by-step explanation:
Let the number of orders made by Malik in the month of January = x
Each order costs = $5
Total cost of decaf mochas in one order = $5x
Malik had cake gift on 1st of January = $200
Amount of money left with Malik at the end of January = $125
Therefore, equation representing this situation will be,
200 - 5x = 125
which expression can he used to find the surface area of the following sqare pyramid
Answer:
answer: A
Because when doing area for triangles its
base × height ÷ 2 so for 1 triangle it would be 5 × 4 = 20 then ÷ by 2 so 20 ÷ 2 = 10 Since there are 4 triangles we will have to add 10 4 times and then for the square it's easily just 4 × 4 = 16
so it would come out to 16 + 10 + 10 + 10 + 10 =
asap please help i really need this question answered
Solve for X
Could you show me what steps to do that leads to the answer
Answer:
x = 76
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
152° is an exterior angle of the triangle , then
x + x = 152
2x = 152 ( divide both sides by 2 )
x = 76
Answer:
x+x=152° (sum of two opposite interior angles is equal to exterior angle)
2x=152°
x=76 °

area of this gigantic ple?
Answer:
1,665
Step-by-step explanation:
First find the area of the whole pizza. The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet. I will use 3.14 for PI since the problem doesn't say what value to use. Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.

Need help
Answer:
[tex]-10x + 4 y + 27[/tex]
Step-by-step explanation:
Answer: -10x+4y+27
Step-by-step explanation: first, combine the like terms
20 + 7= 27
-9x-x=-10x
4y stays the same so, if simplified this equals
-10x+2y+27
Solve for y
4(x + 1) = y - 8
Answer:
4x+4 = y-8
4x = y-8-4
4x= y-12
-y = -12 - 4x
y = 12 + 4x

Answer: B. Yes, Because 3^2 + 4^2 = 5^2
Step-by-step explanation:
ONLY FOR RIGHT TRIANGLES
the biggest side is square root of the sum of the smaller sides squared(a^2 + b^2 = c^2)
So:
3^2 + 4^2 = 5^2
9 + 16 = 25
25 = 25

What is the area of circle circumscribing a triangle?
An imaginary tangent line stretching from the triangle's two sides plus a section of the curve that is tangent to one side create this combination. The formula for the radius of a circle enclosing a triangle is
r = ABC / 4A.
Solution:
area of sector ABC = 85/360 × π × (7.3)² cm²
= 39.53 cm²
area of triangle ABC = 1/2 × 9 × 5.7 cm²
= 25.65 cm²
area of shaded region = area of sectot ABC ₋ area of triangle ABC
= 39.53 ₋ 25.65
= 13.88 cm²
Hence the area of shaded region is 13.88 cm²
