The volume of a pyramid with base area B and height h is 1/3 Bh. Jill makes candles shaped like pyramids to sell at a craft fair. The candles are 6 inches tall and have a base area of 4 square inches.
What is the volume of one of the candles?
Write your answer as a whole number or decimal.
Please HELP!!!!!
The volume of one of the candles is 8 cubic inches.
Given that, the volume of a pyramid with base area B and height h is 1/3 Bh.
What is the volume?Volume is the measure of the capacity that an object holds.
Formula to find the volume of the object is Volume = Area of a base × Height.
Height of pyramid = 6 inches and area of a base = 4 square inches
Now, volume =1/3 ×B×h
= 1/3 ×4×6
= 8 cubic inches
Hence, the volume of one of the candles is 8 cubic inches.

-6x+9y=-12
2x+y=0 i need help quick.
Need the answer for x and y
Answer:
x = 1/2 y = -1
Step-by-step explanation:
2x + y = 0
⇒ y = -2x
Substitute y = -2x into -6x + 9y = -12 to find x:
⇒ -6x + 9(-2x) = -12
⇒ -6x - 18x = -12
⇒ -24x = -12
⇒ x = 1/2
Substitute the found value of x into y = -2x to find y:
⇒ y = -2(1/2) = -1
If the length of the cushion measures 14 in, the width measures 7 in, and the height measures 4 in, how much fabric does Greg need to cover the cushion?
Answer:
364 square inches
Step-by-step explanation:
Surface area = 2(length)(width) + 2(length)(height) + 2(width)(height)
= 2(14)(7) + 2(14)(4) + 2(7)(4)
= 196 + 112 + 56
= 364 square inches

Answer the question below
Answer:
x=-1
y=-5
Step-by-step explanation:
(7x+y)-(x+y)=-6
6x=-6
x=-1
-1+y=-6
y=-5
Answer:
(-1, -5)
Step-by-step explanation:
Solve x + y = -6 for x
[tex]x + y = -6[/tex]Subtract y from both sides.
[tex]x + y - y = -6 - y[/tex] [tex]x = -y - 6[/tex]Substitute -y - 6 for x in 7x + y = -12
[tex]7(-y-6)+y=-12[/tex]Simplify both sides.
[tex]-6y - 42 = -12[/tex]Add 42 to both sides.
[tex]-6y - 42 + 42 = -12 + 42[/tex] [tex]-6y = 30[/tex]Divide both sides by -6.
[tex]\frac{-6y}{-6} = \frac{30}{-6}[/tex] [tex]y = -5[/tex]Substitute -5 for y in x = -y - 6
[tex]x = -(-5) -6[/tex]Simplify both sides of the equation.
[tex]x = 5 - 6[/tex] [tex]x = -1[/tex]Therefore, the answer is (-1, -5).

If x + 4y = 5 and 5x + 6y = 7, then what is the value of 3x + 5y?
Answer:
Option DStep-by-step Solution:
=> x + 4y = 55x + 6y = 7
=> 3(x + 4y = 5)2(5x + 6y = 7)
=> 3x + 12y = 1510x + 12y = 14
=> 3x + 12y = 15-10x - 12y = -14
=> -7x = 1=> x = -1/7=> x + 4y = 5=> -1/7 + 4y = 5=> 4y = 5 + 1/7=> 4y = 35/7 + 1/7=> 4y = 36/7=> y = 9/7=> 3x + 5y => 3(-1/7) + 5(9/7)=> -3/7 + 45/7=> 42/7=> 6Hence, Option D is correct.
Consider the polynomial function. f(x)=x^4+2x^3-11x^2-5x-6. Which statement correctly describes the number of possible positive zeros and the number of possible negative zeros?
The statement which correctly describes the number of possible positive zeros and the number of possible negative zeros is
The number of positive zeros is 1. The number of negative zeros is either 3 or 1From the polynomial function[tex]f(x)=x^4+2x^3-11x^2-5x-6[/tex]
there is only one sign change
So, there is a maximum of 1 positive zero
[tex]f(-x) = (-x)^4 + 2(-x)^3 - 11(-x)^2 - 5(-x) - 6\\\\f(-x) = x^6 - 2x^3 - 11x^2 + 5x - 6[/tex]
Sign changes 3 times
So, number of negative zeros is either 3 or 1

A rectangular field is ten times as long as it is wide. If the perimeter of the field is 1430 feet, find the length and width of the field?
Answer:
below
Step-by-step explanation:
The steps to solve this are:
The perimeter of a rectangle is given by p=2(l+w) where p is the perimeter, l is the length and w is the width. We are told the length of the field is 10 times the width so l=10w. Using this in the formula above we get:
2090=2(10w+w)
22w=2090
w=95 ft
l=950 ft
