Answer:
128.25 = y
Step-by-step explanation:
513=4y
to get y by itself, divide both sides by 4
513/4 =4y/4
513 divided by 4 is 128.25
128.25 = y
Find the surface area of this triangular prism.
Answer:
96
Step-by-step explanation:
A=Area
Using the formulas
[tex]A= 2A_{b} +(a+b+c)h\\A_{b} = \sqrt{s(s-8)(s-10)(s-6)} \\s= \frac{8+10+6}{2}[/tex]
Solving for A
[tex]A=ah+bh+ch+\frac{1}{2}*\sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4}[/tex]
[tex]A=8(2)+10(2)+6(2)+\frac{1}{2}*\sqrt{-8^{4} +2*(8*10)^{2} +2*(8*6)^{2}-10^{4} +2*(10*6)^{2}-6^{4} }[/tex][tex]A=96[/tex]

What does the expression 4+x+x equal?
Name the relationship
A.complementary
B.linear pair
C.vertical
D.adjacent
Answer:
∠a and ∠b are the adjacent angles.
Therefore, option D i.e. adjacent is the correct option.
Step-by-step explanation:
Given the angles
∠a∠bWe know that the two angles are termed as the adjacent angles when they share the:
common vertexcommon sideFrom the given diagram, we are given the angles ∠a and ∠b.
It is clear that angles ∠a and ∠b have a common vertex and common side.
Therefore, the relationship between the angles ∠a and ∠b is 'adjacent'.
In other words, ∠a and ∠b are the adjacent angles.
Please note that the given relation can not be a 'linear pair' because the sum of two angles is NOT a straight line or 180°.
Therefore, option D i.e. adjacent is the correct option.
Consider the function f(x) = 3x and a translation of f(x) named g(x). Janeen created a table for select values of x. Her table is shown below.
A 3-column table has 4 rows. Column 1 is labeled x with entries 0, 1, 2, 3. Column 2 is labeled f (x) with entries 1, 3, 9, 27. Column 3 is labeled g (x) with entries 3, 9, 27, 81.
What can be concluded about the relationship between the two functions? Check all that apply.
The functions have the same base.
The functions have the same range.
The functions have the same exponent.
The functions have the same domain.
g(x) is a translation left 1 unit.
g(x) is a translation right 2 units.
g(x) is a translation up 2 units.

Find the volume of the composite solid.
Answer:
768 m^2
Step-by-step explanation:
Separate the shapes
We can first separate the triangular pyramid from the rectangular prism.
We can calculate them separately.
Calculate
The volume of the triangular pyramid is the base multiplied by the height divided by 3. The base of the pyramid has the same base as the prism so:
8 * 8 = 64
Then we need the height which is 6 so:
64 * 6/3 = 64 * 2 = 128 m^2
Then we calculate the volum of the prism; the formula for that side times side time side:
8 * 8 * 10 = 640 m^2
The total volume is them added up:
128 + 640 = 768 m^2

The image of the point (2,−8) under a translation is (−2,−6). Find the coordinates of the image of the point (5,2) under the same translation.
Answer:To find a translation image of a shape, you can use the following rule or formula. Suppose you want to translate or slide point P a units horizontally and b units vertically. Then, change the x-values and y-values of the coordinates of P. The points of the triangle of are A(-3, 1), B(-4, 3), and C(-2, 4).

Consider the Parallelogram
If the perimeter of the parallelogram is 60, what is the length of HG?
Answer:
The length of HG = 11 units
Step-by-step explanation:
We know that opposite sides of a parallelogram are equal.
so
EF = GHand
FG = EHGiven that
FG = 2x+5
so
EH = 2x+5
also
EF = 3x-10
so
GH = 3x-10
Given that the Perimeter of a parallelogram = 60
As the perimeter of a parallelogram is the sum of all the sides, so
FG + EH + EF + FH = 60
substituting FG = 2x+5, EH = 2x+5, EF = 3x-10, GH = 3x-10
(2x+5) + (2x+5) + (3x-10) + (3x-10) = 60
remove parenthese
2x+5 + 2x+5 + 3x-10 + 3x-10 = 60
group similar elements
2x + 2x + 3x + 3x + 5 + 5 - 10 - 10 = 60
10x - 10 = 60
10x = 60+10
10x = 70
divide both sides by 10
10x/10 = 70/10
x = 7
Therefore, the value of x = 7
Thus,
The length of HG = 3x-10 = 3(7) - 10 = 21 - 10 = 11 units
Hence,
The length of HG = 11 units
Help me plz! Help plz plz plz
Answer:
Function A's slope>Function B
Step-by-step explanation:
So first we see that the y-intercept of function A is 2 (we see (0,2) as a point on the graph) and we know that it's linear. So this leaves us with
mx+2=y.
Now we can just plug in to solve for m!
m+2=6
(Subtract 2 from both sides)
m=4
So the slope of function A is 4.
Next we move onto function B.
We can clearly see that the function is decreasing, meaning that function A's slope is greater.

Hey there!
The answer to your question is [tex]\frac{1}{20}[/tex]
To solve this we must divide [tex]\frac{1}{4}[/tex] by [tex]5[/tex].
To do this, we can multiply [tex]\frac{1}{4}[/tex] by the reciprocal of [tex]5[/tex], or [tex]\frac{1}{5}[/tex].
[tex]\frac{1}{4} * \frac{1}{5}[/tex]
[tex]\frac{1}{20}[/tex]
Therefore, Andy used [tex]\frac{1}{20}[/tex] of a can of paint on each wall of his house.
Hope it helps, have a great day, and stay safe! You've got this!
