-5 (3 x + 1)
The explanation:
Simplify:
(5 x - 20) + (10 - 15)
Grouping like terms, 5 x - 20 x - 15 + 10 = (5 x - 20 x) + (10 - 15):
(5 x - 20 x) + (10 - 15)
5 x - 20 x = -15 x:
- 15 x + (10 - 15)
10 - 15 = -5:
-5 - 15 x
Factor: -5 out of -15 x - 5:

Math problems, yay PLS HELP-
Answer:
235.62
Step-by-step explanation:
First you need to find the area of the big circle as a whole the equation is
A = pir^2
you need to plug in the radius of the big circle which would be
A = pi(10)^2
which equals
314.16
Then you need to find the area of the unshaded circle in the middle using the same formula but replacing the 10 with a 5
which equals
78.54
We then subtract the 78.54 from the 314.16 and we get 235.62 which is the area of the shaded circle to the right

w=3x+7y solve for y in doing a class paper and im super confused
To solve for y, we need to isolate it. Start by moving all of the values on the side the y is on that don't have y to the other side (kind of confusing the way I said it). By that, I mean subtract 3x from both sides:
W = 3x + 7y
W - 3x = 7y
Now, divide both sides by 7 to find the value of y:
W - 3x = 7y
(W - 3x)/7 = y

The measure of c is___.
Answer:
10
Step-by-step explanation:
it is because of Pythagoras's theorem: that the sum of the squares of the two lines that form a right angle, must add up to the square of the hypotenuse (c). So 6²+8² is 100, which is the square of 10.
Answer:
10
Step-by-step explanation:
Pythagorean Theorem tells us that (6)a^2 plus (8)b^2 = (10)c^2
6^2 = 36
8^2 = 64
36 + 64 = 100
sqrt of 100 = 10
c = 10

Chase a has locker that is 2 ft. wide, 2 ft. deep, and 5 ft. high. How many boxes of fundraising candy can he fit into his locker if each box is 1 ft.3 in volume?
Answer:
16 boxes of candy
Step-by-step explanation:
since 12 inches fit in one foot, 3 inches are basically 3/12 or 1/4
the volume of the locker = width x depth x height. 2x2x5=20
20 divided by 1 1/4=20 divided by 5/4=20*4/5=80/5=16
Answer:
20 boxes of fundraising candy can fit in his locker.
Step-by-step explanation:
because V= l x w x h. 2 x 2 x 5= 20, since you know that the volume is 1. Divide 1 and 20, you still get 20.

Step-by-step explanation: but anyway go to my page then click on questions go to the first on type and answer and get free points and hearts :)
Answer:
C. y=3/4x-3
Slope: 3/4
y-intercept: -3
Equation: y=3/4x-3
Make a table with x and y just like the one shown below
X:Y
0:-3
4:0
As you can see when x is 0 y equals (-3)
That (-3) is your y-intercept
Now we're going to save that for later
Then you do 0-(-3) and 4-0
You should get positive numbers of 3 and 4
Now you do y/x and that will be 3/4
That 3/4 is your slope
We're going to bring back that (-3) we got earlier and make the equation
The equation is y=3/4x-3
Make sure that you check your work as well
I hope you understand what I'm saying here :)
1# What is the side length of a square with an area of 1/16 square units?
2# What is the volume of a cube with edge lengths of 2/3 units?
3# What is the edge length of a cube with a volume of 27/64 cubic units?
Answer:
#1 1/4
#2. 8/27
#3 3/4
Step-by-step explanation:
let the side of the square be y
Area of a square = y x y = y^2
y^2 = 1/16
y = sqrt (1/16)
y = 1/4
volume of a cube = edge length x edge length x edge length
Volume of a cube = 2/3 * 2/3 * 2/3
Volume of a cube = 8/27
volume of a cube = (edge length)^3
Edge length = cube root (volume of a cube)
Edge length = cube root (27/64)
Edge length = 3/4

4. 4.5mm^2
Step-by-step explanation:
1. Surface area:
2m^2 (area of face) * 6 (# of faces)
=12m^2 or 12 square meters.
Volume: (2m)^3=8m^3 or 8 cubic meters.
2. a=v+3, l=v-2
because if we rewrote exactly what the problem says, "Anna is 3 years older than Vickie" that is mathematically a=v+3. Do the same with the other equation.
3. 5.275+8.36g when g=120 is 5.275+1003.2, or 6.278.2, which is more than 6000, so the bridge would not hold Melinda's truck and 120 gallons of water.
4. 2s^2 + 4sh when s=0.5mm and h=2mm:

help please I need to find the area but I don't know how
Answer:
Let's find the area of the rectangle below since we are given lengths.
Formula for area of a rectangle:
a = w * l, where "w" is the width and "l" is the length
The width is 24 and the length is 8 yards, so let's multiply those;
a = 24 x 8
a = 192 square yards
Now that we have found one of the areas, let's find the triangle above.
Though we are not given the base of the triangle, we can find the triangle's base by adding the other two side lengths beside it and subtract it by the total width.
The other two side lengths are 6 and 6, the total width is 24 as shown under the rectangle.
So we add the two side lengths (6 + 6) = 12, and subtract it from it's total, 24, (24 - 12) = 12
Now that we have found the base of the triangle, we must find the height of the triangle (the dotted line that runs vertically through the triangle).
The height of the rectangle is 8, the total of the dotted line that runs through both the triangle and the rectangle is 16.
Now we just subtract 8 from the total of the dotted line to get our height of the triangle, (16 - 8) = 8, finally we can find the area of the triangle.
Formula for area of triangle;
A = BH x 1/2, where "b" is the base and "h" is the height.
Replace b and h:
A = 12(8) x 1/2
A = 96 x 1/2
A = 96/2
A = 48 square yards
Since we found the area of the two shapes, we must add them to get the total area.
Area of rectangle: 192
Area of triangle: 48
We add;
192 + 48 = 240 square yards, is your answer.

A student spins a spinner that has 3 equal sections labeled A, B, and C and then tosses a six-sided number cube.
What is the sample space for this compound event?
A: {A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}
B: {A, B, C, 1, 2, 3, 4, 5, 6}
C: {ABC1, ABC2, ABC3, ABC4, ABC5, ABC6}
D: {A6, B6, C6}
Answer:
{A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}
Step-by-step explanation:
I took the test
The sample space of the compound event of spinning a spinner and tossing a six-sided number cube is {A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}, the cartesian product of the sample spaces of the two events. Hence, option A is the right choice.
What is a cartesian product?An ordered set of sets is used to define a Cartesian Product. It's the collection of all conceivable ordered combinations made up of one member from each of the sets.
The set containing all ordered pairs (p, q), where p is an element of P and q is an element of Q, is the Cartesian product of two sets, P and Q, represented as P*Q.
How do we solve the given question?We are given that a student spins a spinner that has 3 equal sections labeled A, B, and C and then tosses a six-sided number cube.
Let the event of getting something on spinner be X.
∴ Sample space of X = {A, B, C}
Let the event of getting something on the number cube be Y.
∴ Sample space of Y = {1, 2, 3, 4, 5, 6}
The sample space of the compound event is the cartesian product of sample space of X with sample space of Y.
∴ Sample space of compound event = {A, B, C}*{1, 2, 3, 4, 5, 6}
or, Sample space = {A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}.
∴ The sample space of the compound event of spinning a spinner and tossing a six-sided number cube is {A1, B1, C1, A2, B2, C2, A3, B3, C3, A4, B4, C4, A5, B5, C5, A6, B6, C6}, the cartesian product of the sample spaces of the two events. Hence, option A is the right choice.

This figure represents a compartment in a container for storing craft supplies. Another compartment is identical except that it is 4 centimeters taller.
What is the difference in volume of the two compartments?
Enter your answer in the box.
cm³
Answer:
280cm^3
Step-by-step explanation:
Find the volume of the original container (490), and subtract that from the volume of the second container (770) to get 280cm^3.
The difference in the volume that the two compartments have:
280 [tex]cm^3[/tex]
Find the volume
Given that,
Sum of parallel sides = 15cm + 5cm
= 20 cm
Height = 7 cm
[tex]= 4 cm[/tex]
To find,
The volume of the compartment = Area of base × Height
= {(1/2) × 20} × 7} × 7
= 490 [tex]cm^2[/tex] ...(i)
Now,
The new compartment's height = 7 + 4
= 11 cm
Volume for the new compartment = Area of base × Height
= 70 × 11
= 770 [tex]cm^3[/tex] ...(ii)
Now,
To find the difference in the volumes,
(ii) - (i)
= 770 - 490
= 280 [tex]cm^3[/tex]
Thus, 280 [tex]cm^3[/tex] is the correct answer.
