Answer: a is 16, b is -8
Step-by-step explanation:
3a-45=3
add 45 to both sides to get rid of -45
3a=48
divide both sides by 3
a = 16
plug 16 into the first equation
16 + b = 8
subtract 16 from both sides
b = -8

Answer:
56.54in^2
Step-by-step explanation:
Answer:
18π in^2 (roughly 56.5 in^2)
Step-by-step explanation:
The area of a semicircle is half the area of a circle. So the area would be 1/2πr² instead of πr².
Since the diameter is 12 inches, the radius would be half of that, making the radius r=12/2=6 inches.
Plugging in r=6 into our formula, we see that the area of the semicircle is 1/2π(6)²=1/2π(36)=18π inches^2
So your final area is 18π in^2 (roughly 56.5 in^2)

Answer:
∠ GHE = 40°
Step-by-step explanation:
∠ IHE and ∠ GHE are adjacent angles and are supplementary, then
∠ GHE + ∠ IHE = 180°
∠ GHE + 140° = 180° ( subtract 140° from both sides )
∠ GHE = 40°

James raises chickens. He tracks the number of eggs his chicken lay at the end of each week. Is this relation a Function? Explain
Answer:
Yes it is a function.
Step-by-step explanation:
It is given that James raises chickens in his farm. and the chicken laid eggs on each day. James keeps a track of the number of eggs that his chicken laid at the end of each week.
This is a function because according to the definition of a function, if each of he input corresponds to exactly one output, then that relation is called as a function.
In this case, every week the chickens lay different number of eggs. So every week corresponds to the different number of eggs laid by the chicken. So it is a function.
Answer:
Yes it is a function because there is a domain/Input for each Range/Output

8. If
VW = 9x-11 and
SU = 16x - 12 find WT
Answer:
WT = 34
Step-by-step explanation:
The ultimate goal here to pinpoint what x is equivalent to. In a rectangle we know that the diagonals are congruent as well as the fact that they bisect each other. This means cutting in half. Using this knowledge we know VW = 9x - 11 is half of SU = 16x - 12.
Step One: Multiply 9x - 11 by 2.
2(9x - 11) = 18x - 22
Step Two: Set up your equation
18x - 22 = 16x - 12
Step Three: Solve for x
18x - 22 = 16x - 12
2x - 22 = -12
2x = 10
x = 5
Step Four: Substitute to check your work
16(5) - 12 = 68
9(5) - 11 = 34
Again, since the diagonals of a rectangle bisect each other VW = WT.
34 is half of 68 proving our findings.
The length of WT is 34.
What is Rectangle?Rectangle is a two dimensional figure which has four sides and four angles and all the angles are right angles.
We have,
VW = 9x - 11
Diagonals of a rectangle bisect each other.
So, WT = 9x - 11
VT = 2(9x - 11)
Also, we have,
SU = 16x - 12
The two diagonals of a rectangle are equal.
2(9x - 11) = 16x - 12
18x - 22 = 16x - 12
18x - 16x = -12 + 22
2x = 10
x = 5
WT = 9x - 11 = (9 × 5) - 11 = 34
Hence the length of the line WT is 34.

Volume = rule area × height
__________________________
The rule is circle and the area of the circle finds using following formula :
Circle area = pi × radius^2
Circle area = 3.14 × 1^2
Circle area = 3.14
___________________________
Volume = 3.14 × 10
Volume = 31.4 in^3
The volume of cylinder having diameter 1 inches and height be 10 inches be 31.4 cubic inches.
What is volume?Volume is amount of substance a container can hold in its capacity. Volume of cylinder is π[tex]r^{2} h[/tex] in which r is radius and h is height of cylinder.
How to calculate volume?We have been given that the diameter of cylinder be 2 inches and height be 10 inches.We have to find the volume of cylinder.
Volume of cylinder=π[tex]r^{2} h[/tex]
Radius=2/2
=1 inch
Now put the value of radius and height in the formula of volume.
Volume=3.14*1*10
=31.4 cubic inches.
Hence the volume of cylinder is 31.4 inches.

C I think
Step-by-step explanation:
What C is essentially saying is that if the lines l and m intersect and form two angles next to each other that are equal then they will be 90 degrees
this is true because if two lines intersect they will form 4 angles and since vertical angles are equal the only way for adjacent angles to be equal is for everything to be 90 degrees which then makes the lines perpendicular
