Answer:
(a) 1.18
(b) 99.71
Step-by-step explanation:
to know the value of q in degrees we can use cosine of q
[tex]\cos (q) = \frac{OR}{OQ}\\\\\cos (q) = \frac{5}{13}\\\\q = \cos^{-1}(\frac{5}{13})\\\\q \approx 67.38[/tex]
now to radians
the formula is
[tex]x\times\frac{2\pi}{360}\\\\[/tex]
with x the degrees
[tex]67.38\times \frac{2\pi}{360}\\\\=\frac{67.38\pi}{180}\\\\\approx 0.374\pi\\\\\approx 1.18[/tex]
so the measure of angle q is 1.18 radians
so now for part b
[tex]A = \frac{r^2 \alpha }{2}\\\\[/tex]
with [tex]\alpha[/tex] being the central angle in radians
for degrees is the following
[tex]A = \frac{\theta}{360}\times \pi r^2[/tex]
so we have
[tex]A = \frac{13^2 (1.18)}{2}\\\\A = 99.71[/tex]cm^2

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.
Consider the Parallelogram
If the perimeter of the parallelogram is 60, what is the length of HG?
Answers
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

Find the volume of the composite solid.
Answers
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

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.

Answers
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.
