Answer:
180=3x+7x+10
simplify
180=10x+10
subtract 10 from both sides
170=10x
divide both sides by 10
x=17
Find the Volume of the figure
Answer:
1920 cm³
Step-by-step explanation:
V = w · h · l
V = 8 · 14 · 10
V = 1120 cm³
Now for the smaller one.
V = w · h · l
V = 8 · 10 · 10
V = 800 cm³
1120 cm³ + 800 cm³
1920 cm³
Answer:
1920 cm ^3
Step-by-step explanation:
find the volume of the 2 cuboids seperatly.
bigger one: LXWXH --> 8 X 14 X 10 = 1120
smaller one: LXWXH --> 10X10X8 = 800
add them up
1120 + 800 = 1920 cm
Hope this helps :D
Which expression is equivalent to (see the picture)
A. 20x-21y +14
B. 20x + 11y + 14
C. 20x - 11y + 6
D. 20x + 21y +6
Answer:
A
Step-by-step explanation:
[tex]\frac{1}{5} (150x-80y+50-50x-25y+20)[/tex]
step 1 apply the 1/5 to everything that inside of the parenthesis
[tex]\frac{150x}{5} =30x\\\\\frac{-80y}{5} =-16y\\\\\frac{50}{5} =10\\\\\frac{-50x}{5} =-10x\\\\\frac{-25y}{5} =-5y\\\\\frac{20}{5} =4[/tex]
we now have 30x - 16y + 10 - 10x - 5y + 4
Step 2 combine like terms
30x - 10x = 20x
-16y - 5y = - 21y
10 + 4 = 14
we're left with 20x - 21y + 14 Which corresponds with answer choice A
Answer:
20x-21y+14
Step-by-step explanation:
1/5(150x-80y+50-50x-25y+20) is equal to 1/5(150x) + 1/5(-80y) + 1/5(50) + 1/5 (-50x) + 1/5(-25y) + 1/5(20)
So if we simplify, we would have 30x + (-16y) + 10 + (-10x) + (-5y) + 4, or 30x -16y + 10 -10x -5y + 4
When organizing the values by variable, the equation would look like this -
30x - 10x -16y -5y + 10 + 4
Combining like terms will result in 20x -21y + 14.
Hope this helps!

Complete the square to make a perfect square trinomial. Then, write a result as a binomial squared. m^2-13m
m^2-13+ ? =( ? )^2
Answer:
Look at the picture
Hope it helped!
Answer: m^2 - 13m + 42.25 = (m - 6.5)^2
notes:
6.5 = 13/2
42.25 = 169/4
======================================================
Explanation:
The coefficient in front of the m is -13. Cut this in half to get -13/2 = -6.5
Then square this result to get (-6.5)^2 = 42.25
We need to add 42.25 to the expression in order to complete the square
This allows us to factor to get m^2 - 13m + 42.25 = (m - 6.5)^2
Note how the equation is in the form
a^2 - 2ab + b^2 = (a-b)^2
where a = m and b = 6.5

1. devin is making a candle by pouring melted wax into a mold in the shape of a square pyramid. each side of the base of the pyramid is 6 cm and the height of the pyramid is 9 cm. to get the wax for the candle, devin melts cubes of wax that are each 4 cm by 4 cm by 4 cm. how many of the wax cubes will devin need in order to make the candle? show your work.
Answer:
1.6875
Step-by-step explanation:
Volume of a pyramid = 1/3 (l*w*h)
Volume = 1/3(6 * 6 * 9)
Volume = 2 * 6 * 9
Volume = 108 cm³
Volume of cube = s³ ; s = side length
Volume = 4³ = 4 * 4 * 4 = 64 cm³
Number of wax cube = Volume of pyramid / volume of cube
= 108 cm³ / 64 cm³
= 1.6875

WHATS THE QUESTION, BRO??
Step-by-step explanation:
A brand of uncooked spaghetti comes in a box that is a rectangular prism with a length of 10 inches, a width of 3 inches, and a height of 4 1/2 inches. What is the surface area?
Answer:
The surface area is 177 square inches
Step-by-step explanation:
Given
[tex]Length = 10[/tex]
[tex]Width = 3[/tex]
[tex]Height = 4\frac{1}{2}[/tex]
Required
The surface area
This is calculated as:
[tex]Area = 2 * (Length * Width + Length * Height + Width * Height)[/tex]
So, we have:
[tex]Area = 2 * (10* 3+ 10* 4\frac{1}{2}+ 3* 4\frac{1}{2})[/tex]
[tex]Area = 2 * (30+ 45+ 13\frac{1}{2})[/tex]
[tex]Area = 2 * (88\frac{1}{2})[/tex]
[tex]Area = 177[/tex]

I'll do problems 13 and 14 to get you started.
=====================================================
Problem 13
Answer: 32 degrees-----------------------
Explanation:
Refer to the diagram below for problem 13. Since BD is a tangent of the circle, this means angle ABD is 90 degrees, and furthermore x+y = 90. This solves to y = 90-x.
If we focus on triangle ABC, then we can add the interior angles and set the sum equal to 180
A+B+C = 180
z+y+y = 180
z+2y = 180
z+2(90-x) = 180 .... plug in y = 90-x
z+180-2x = 180
z-2x = 180-180
z-2x = 0
z = 2x
We'll use this later.
Now move onto triangle ABD. This is a right triangle due to angle ABD being 90 degrees. The acute angles z and 26 are complementary, meaning they add to 90. So,
z+26 = 90
z = 90-26
z = 64
Now plug this into z = 2x and solve for x
z = 2x
64 = 2x
2x = 64
x = 64/2
x = 32
=====================================================
Problem 14
Answer: 31 degrees-----------------------
Explanation:
Refer to the image shown below for problem 14. Like before, I've added various labels to it to help find the angle we're after (the red angle x).
Note how I've drawn a dashed line from point A to point D. This splits up quadrilateral ABCD into two triangles ABD and ACD. These triangles can be shown to be congruent using the HL (hypotenuse leg) theorem.
The congruent triangles also implies that angle DBC and angle BCD are the same measure (both are shown in green as the variable y).
Focus on triangle BCD. It has interior angles of: y, y and 62. Add them up, set the sum equal to 180.
y+y+62 = 180
2y+62 = 180
2y = 180-62
2y = 118
y = 118/2
y = 59
As the image attachment mentions, the angles x and y add to 90 degrees. This is because angle ABD is 90 degrees, due to segment BD being tangent to the circle. So x+y = 90 leads to x = 90-y, and therefore,
x = 90-y
x = 90-59
x = 31
Side note: it is not a coincidence that we ended up with half of the value of 62.

Put the steps in correct order to prove that if x is irrational, then 1/x is irrational using contraposition.
a. Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.
b. Hence x is rational.
c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.
d. Observe that x is the quotient of two integers with the denominator nonzero.
Answer:
The correct order is:
a
c
d
b
Step-by-step explanation:
First, let's write 1/x in a convenient way for us:
a) Substitute 1/x = p/q, to obtain x = 1/(1/x) = 1/(p/q) = q/p.
Now we assume that 1/x is rational (we want to prove that this implies that x will be also rational and because we know that x is irrational assuming that 1/x is rational will lead to an incongruence), then:
c. If 1/x is rational, then 1/x = p/q for some integers p and q with q ≠ 0. Observe that p is not 0 either, because 1/x is not 0.
Now we know that we can write x as a quotient of two integers, we need to imply that, then the next one is:
d) Observe that x is the quotient of two integers with the denominator nonzero.
And that is the definition of rational, then we end with:
b) Hence x is rational.
Which is what we wanted to get.
Solve for X. What does X equal?
Step-by-step explanation:
Apply angle sum of triangle, that means the sum of all interior angles in a triangle is equal to 180°.
So that, (x + 45) + 50° + 90° = 180°.
However when we simply do 45+50+90, the answer is already bigger than 180.
So the question is made wrong.
