Answer:
1350 cm³
Step-by-step explanation:
Given 2 similar solids with sides in the ratio a : b , then
ratio of volumes = a³ : b³
Here the ratio of heights of A : B = 10 : 15 = 2 : 3 , thus
ratio of volumes A : B = 2³ : 3³ = 8 : 27
let x represent the volume of B then using proportion
[tex]\frac{8}{400}[/tex] = [tex]\frac{27}{x}[/tex] ( cross- multiply )
8x = 10800 ( divide both sides by 8 )
x = 1350
The volume of solid B = 1350 cm³
solve using eliminates method 3x-4y=15 2x-2y=8

The answer in this question is Alternate interior angles are congruent.
Step-by-step explanation:
Alternate interior angles are defined as when the two lines are crossed by another line which is called transversal, the pairs of angles on opposite sides of the transversal but inside the two lines are known as alternate interior angles.
A jar contains 56 quarters and pennies. The total value of the coins is $3.92. Which system of equations can be used to find p, the number of pennies, and q, the number of quarters?
Answer:
let x = the number of nickels
the number of pennies can be represented by (56 - x)
.05x + .01(56 - x) = 1.52
5x + (56 - x) = 152 if in the above line we multiply both sides of the equation by 100
4x + 56 = 152
4x = 96
x = 24
There are 24 nickels and 56 - 24 = 32 pennies
24 nickels are worth 24 * 5 = $1.20 and 32 pennies are obviously worth 32 cents, so the total is 1.20 + 0.32 = $1.52

Find the degree of each polynomial.
The perimeter of a room is 43 ft. The width is 9 1 2ft. What is the length?
Answer: The length is 12 ft.
Step-by-step explanation:
So a room is likely to be in a shape of a rectangle. And to to find the perimeter of a rectangle will use the formula P = 2w + 2l so in this case we know the perimeter and and the width but we need to find the length.
so using the formula we could do this
43 = 2(9.5) + 2l
43 = 19 + 2l subtract 19 from both sides
-19 -19
24 = 2l Divide both sides by 2
l = 12
The length is 12.
Check: 43 = 2(9.5) + 2(12)
43 = 19 + 24
43 = 43 correct so the length is 12.

Step-by-step explanation:
h(x) = 0 m , when the ball is on the ground.
h(x) = - (x-2)² + 16
0 = - (x-2)² + 16
(x-2)² = 16
√(x-2)² = +/- √16
(x-2) = 4 , (x-2) = - 4
x - 2 = 4 , x = -2
x = 6

Step-by-step explanation:
Given f(x) = 3/4x + 12, find the value of x when f(x) = x.
Answer:
48 =x
Step-by-step explanation:
3/4x + 12 = x
Subtract 3/4 x from each side
3/4x + 12-3/4x = x-3/4x
12 = 1/4x
Multiply each side by 4
12*4 =1/4x *4
48 =x
Answer:
x=48
Step-by-step explanation:
f(x) is basically just another way to write y.
If f(x)=x, then y=x.
x=3/4x+12 (Original Equation Substituting x for f(x), equal to y)
1/4x=12 (Subtract 3/4 from both sides of the linear equation)
x=48 (Multiply both sides by 4)
9. Determine the equation of a line that passes though the points (3,-4) and (6,2). [
Answer:
y=2x-10
Step-by-step explanation:
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
First, let's find what m is, the slope of the line...
The slope of a line is a measure of how fast the line "goes up" or "goes down". A large slope means the line goes up or down really fast (a very steep line). Small slopes means the line isn't very steep. A slope of zero means the line has no steepness at all; it is perfectly horizontal.
For lines like these, the slope is always defined as "the change in y over the change in x" or, in equation form:
So what we need now are the two points you gave that the line passes through. Let's call the first point you gave, (3,-4), point #1, so the x and y numbers given will be called x1 and y1. Or, x1=3 and y1=-4.
Also, let's call the second point you gave, (6,2), point #2, so the x and y numbers here will be called x2 and y2. Or, x2=6 and y2=2.
Now, just plug the numbers into the formula for m above, like this:
m=
2 - -4
6 - 3
or...
m=
6
3
or...
m=2
So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

The list price of an item is $ 93.45. The supplier is offering a series trade discount of 7/23. Find the net cost.
Answer: $66.92
Step-by-step explanation:
We can get the final price by calculating the first discount and then subtracting this from the original price to get the amount to which the second discount is applied. We can then determine the final price by subtracting the second discount from the intermediate price.The percent of the first discount is 7.
The price after the first discount is $93.45−($93.45×0.07)=$86.91.
The price to which the second discount is applied is $86.91.
The second discount is 23%
86.91 x 0.23 = $19.99
The final price is (86.91 - 19.99) = 66.92

Step-by-step explanation:
find,in terms of pie,the curved surface area of a cone with circular base diameter 10cm and height 12cm
Answer: 65π
Step-by-step explanation:
you can draw the cone to make it easier for you to understand.
to find the curved surface area of a cone, you multiply the base radius of the cone by pie. Then multiply your answer by the length of the side of the cone.
to do this you need the length of the side and the radius of the cone.
to find radius, divide the diameter by 2.
[tex]\frac{10}{2}[/tex] = 5
then use the right angle triangle in the cone to find the length of the side
use Pythagoras theorem which states that a² + b²= c²
a= 5, b= 12, c= x (length of side)
∴[tex]x^{2} 5^{2} + 12^2 =x^{2} \\25 + 144 = x^{2} \\169= x^{2} \\x=\sqrt{169} \\x= 13[/tex]
no that you have found the length
multiply the base radius by pie
which is:
5 ×π = 5π
then multiply this by the length of the side
5π × 13 = 65π
there you go!

Hosn is a picture framer. He is framing a picture that is 24 inches by 32 inches with a
frame that is 2.5 inches wide. What is the outer perimeter of the framed picture In yards, feet, and inches.
Answer: 122 sq. in.
Step-by-step explanation:
P = 2 (l + w)
P = 2 (34.5 + 26.5)
P = 2 x 61
P = 122 sq. in. = 0.847 sq ft = 0.0941 sq. yards
Perimeter is the sum of the side lengths of a shape. The outer perimeter of the framed picture is:
132 inches3.67 yard11 feetGiven that:
[tex]Length = 24in\\Width = 32in[/tex]
The width of the frame is given as:
[tex]Frame =2.5in[/tex]
So, the actual length and width of the framed picture is:
[tex]Length =24 + 2.5 + 2.5[/tex]
[tex]Length =29in[/tex]
[tex]Width = 32 + 2.5 + 2.5[/tex]
[tex]Width = 37in[/tex]
The outer perimeter (P) in inches is:
[tex]P= 2 \times (Length + Width)[/tex]
So, we have:
[tex]P= 2 \times (29in + 37in)[/tex]
[tex]P= 132in[/tex]
The perimeter in yard, is as follows:
[tex]P= \frac{132}{36}yd[/tex]
[tex]P = 3.67yd[/tex]
The perimeter in feet is as follows:
[tex]P= \frac{132}{12}ft[/tex]
[tex]P = 11ft[/tex]
Hence, the outer perimeter of the frame is 132 inches

Graph the line y = -5/4x-3
Answer:
Well I can't exactly graph for you but I will tell you the y intercept is at (0,-3) and the slope is -5/4
Step-by-step explanation:
Make a graph and plot a point on (0,-3)
Then go down 5 and go right 4 to represent the slope of -5/4
Hope this helps!
The graph of line y= -5/4x -3 is attached below.
We have the equation
y= -5/4x - 3.
To graph the line y = -5/4x - 3, you can use the slope-intercept form of a linear equation, which is y = mx + b.
In this equation, "m" represents the slope, and "b" represents the y-intercept.
From the given equation, we can determine that the
slope (m) is -5/4, and the y-intercept (b) is -3.
The graph of the line y = -5/4x - 3 should look like a downward-sloping line that passes through the points (0, -3), (4, -8), and (-4, -2).
