Answer:
y + 12 = 6(x - 5)
Step-by-step explanation:
Use the point-slope formula: y - k = m(x - h).
Here we have y + 12 = 6(x - 5)
Find each pair of similar solids, find the ratio of the volume of the first figure to the volume of the second
Step-by-step explanation:
Scale factor = 4/3. Therefore radius if larger cone = 4r/3 where r is the radius of the smaller cone and height of larger cone = 4h/3 where h is the height of the larger cone.
So ratio of volumes = r^2 * h/(4r/3)^2 * 4h/3) = 9/16 * 3/4 = 27/64
30 is a similar process except it's cylinders so find the scale factor and go on with that problem.

break-even point?
A. Costs of $3000 and revenues of $5000
B. Costs of $3000 and revenues of $4000
C. Costs of $4000 and revenues of $4000
D. Costs of $4000 and revenues of $5000
Answer: C. Costs of $4000 and revenues of $4000
Step-by-step explanation: took the quiz.
The break-even point for a given company can be Costs of $4000 and revenues of $4000
What is a break-even point?The break-even point is the point at which total cost and total revenue are equal, meaning there is no loss or gain for your small business.
Given are some options we need to find a condition for a company to have a break-even point
Since, the break-even point is a condition of no loss no gain, that the difference of the cost and revenue is zero, that stage is called a break-even point.
From the options, option C is showing a condition of neither gain nor loss, it's having both cost and the revenue same = $4000
Hence, the break-even point for a given company can be Costs of $4000 and revenues of $4000

Yes, because both ratios show a pair of numbers that have a difference of 1.
Yes, because any combination of silver and green will work.
No, because the numbers in the given ratio must be multiplied by the same number.
No, because there cannot be more than 4 green parts.
Answer:
No, because the numbers in the given ratio must be multiplied by the same number.
Step-by-step explanation:
Essentially, ratio to be equal must be equal. E.g. 3:4 would be equal to 6:8 because you multiply both sides of the ratio by 2.

A square pyramid and its net are shown below. What is the surface area of the pyramid?
Answer:
736 Maybe
Step-by-step explanation:
Well what you gotta do is the triangles on the sides can be moved to form mini rectangles. When you do this you get 8 by 15 rectangles and since you have 4 of then you multiply those by 4. 8*15= 120 and 120*4 = 480. Then all you need to fing is the center square pretty easy to find that square right. Its just 16*16 = 256. And 480+256=736.
I hope this helps.
The surface area of the square base pyramid is 736 cm².
Surface area = A + 1 / 2 ps
where
A = base area
p = perimeter of the base
s = slant height
Therefore,
A = 16² = 256 cm²
p = 4(16) = 64 cm
s = 15 cm
surface area = 256 + 1 / 2 × 64 × 15
surface area = 256 + 480
surface area = 736 cm²

What is the missing leg length
Answer:
b = 16
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
12^2 + b^2 = 20^2
144+b^2 = 400
Subtract 144 from each side
b^2 = 400-144
b^2 = 256
Take the square root of each side
sqrt(b^2) = sqrt(256)
b = 16

Theresa is comparing the graphs of y=2x and y=5x. Which statement is true?
The y-intercept of y=2x is (0, 2), and y-intercept of y=5x is (0, 5).
Both graphs have a y-intercept of (0, 1), and y=2x is steeper.
Both graphs have a y-intercept of (0, 1), and y=5x is steeper.
Neither graph has a y-intercept.
Answer:
Both graphs have a y-intercept at 0,1. The y=2^x is steeper than y=5^x
Step-by-step explanation:
If you graph these on a graphing calculator you will clearly see they have the same y-intercept (0,1) and that y=2^x is steeper.
The correct option is option B that is both graphs have a common y-intercept of (0, 1) and y = 2x is steeper.
What is the intercept of a line ?
The point where the line or curve crosses the axis of the graph is called intercept. If a point crosses the x-axis, then it is called the x-intercept.
Theresa is comparing graphs of y = 2x and y = 5x
The y-intercept is the point where a graph crosses the y-axis. In other words, it is the value of y when x = 0.
Let's check
which is y = 2x.
For x = 0 , y = 0
for x = 1 , y = 2
So , here y-intercept will be (0,2)
So , for both the values y - intercept exists for first function which is y = 2x.
Similarly, for y = 5x , there will be a y -intercept of (0,5).
Both graphs have a common y-intercept of (0, 1).
We know that if the slope of the graph is steeper then we can say that the tangent of the angle made by it will be more and it will make more angle with the x axis.
Here , y = 2x is more steeper than y = 5x.
Therefore , the correct option is option B that is both graphs have a common y-intercept of (0, 1) and y = 2x is steeper.

a rectangular field has side lengths that measure 9/10 mile and 1/2 mile what is the area of the field
Answer:
[tex]\frac{9}{20}miles^2=0.45miles^2[/tex]
Step-by-step explanation:
To find the area of a rectangle:
[tex]a=l*w[/tex]
where [tex]l[/tex] is the length and [tex]w[/tex] is the width.
In this case:
length: [tex]l=\frac{9}{10}miles[/tex]
width: [tex]w=\frac{1}{2} miles[/tex]
thus, we multiply this quantities to find the area:
[tex]a=(\frac{9}{10} miles)(\frac{1}{2}miles )\\\\a=\frac{9*1}{10*2}miles^2\\ \\a=\frac{9}{20}miles^2[/tex]
the area of this rectangle is 9/20 miles squared, or what is the same 0.45 miles squared

A company is trying to calculate the amount of
concrete that will be needed to create one concrete
block that is in the form below.
The concrete block is a rectangular prism with two
cubes cut out. The cubes have a side length of 6
inches.
What is the total volume, cubic feet, of concrete
needed to make this block?
Answer:
[tex]0.19\,\,cubic\,\,feet[/tex]
Step-by-step explanation:
Given:
The concrete block is a rectangular prism with two cubes cut out. The cubes have a side length of 6 inches.
To find: total volume, cubic feet, of concrete needed to make this block
Solution:
Side of cube = 6 inches
Volume of cube = [tex](side)^3=6^3=216\,\,cubic\,\,inches[/tex]
So, volume of two cubes = 2(216) = 432 cubic inches
Length of rectangular prism = 12 inches
Breadth of rectangular prism = 8 inches
Height of rectangular prism = 8 inches
Volume of rectangular prism = length × breadth × height = [tex]12(8)(8)=768 \,\,cubic\,\, inches[/tex]
Total volume of concrete needed to make this block = Volume of rectangular prism - Volume of two cubes = 768 - 432 = 336 cubic inches = [tex]\frac{336}{1728} =0.19\,\,cubic\,\,feet[/tex]
( use 1 cubic inch = [tex]\frac{1}{1728} \,\,feet[/tex])
What is a reasonable estimate for the volume of a number cube:
8 cm3, 27 in?, or 1 ft??
