to solve better, im throwing 60 near 180. 60° is going to be -60 cause of it.
3y=180-60 = 3y=120
now im dividing both 3. because both can divide by 3.

A. 240 in. 2
B. 248 in. 2
C. 288 in. 2
D. 258 in.2
Answers
Answer:
Option C.
Step-by-step explanation:
It is given that the surface area of a rectangular prism, is
[tex]SA=2(ab+ac+bc)[/tex]
where a, b, and c represent the lengths of the edges of the prism.
We need to find the surface area of this prism if a = 12 inches, b = 6 inches, and c = 4 inches.
Substitute a=12, b=6 and c=4 in the above formula.
[tex]SA=2((12)(6)+(12)(4)+(6)(4))[/tex]
[tex]SA=2(72+48+24)[/tex]
[tex]SA=2(144)[/tex]
[tex]SA=288[/tex]
The surface area of this prism is 288 sq.inches.
Therefore, the correct option is C.

2. 3x - 5y = -2
x + 3y = 4
Let us multiply equation 2 by three, so we can use the elimination method.
3x + 9y = 12
Now, let us subtract equation 1 from equation 2.
3x + 9y - 3x + 5y = 12 + 2
14y = 14
y = 1
Let us substitute this value of y in equation 2.
x + 3(1) = 4
x = 4 - 3
x = 1
3. -3x + 3y = -6
6x + 4y = 42
Let us multiply equation 1 by 2, so we can use the elimination method.
-6x + 6y = -12
Let us now add equations 1 and 2, so as to eliminate x.
6x + 4y -6x + 6y = 42 - 12
10y = 30
y = 3
Let us now substitute this value of y in equation 1, so as to find x.
-3x + 3(3) = -6
-3x + 9 = -6
-3x = -15
3x = 15
x = 5
4. 12x + 4y = 20
2x - 2y = -2
Let us multiply equation 2 by 2, so as to use the elimination method.
4x - 4y = -4
Let us now add equations 1 and 2, so as to eliminate y.
4x - 4y + 12x + 4y = -2 + 20
16x = 18
x = [tex]\frac{18}{16}[/tex] = [tex]\frac{9}{8}[/tex] = 1.125
Let us substitute this value of x in equation 2, so as to find y.
2(9/8) -2y = -2
9/4 - 2y = -2
-2y = -2 - 9/4
2y = 17/4
y = [tex]\frac{17}{8}[/tex] = 2.125

3. The area of the base of a can is 45 square inches. Its height is 12 inches. If 1/3 of the
height is cut off, what will be the volume of the can?*
a) 540 cubic inches
b)180 cubic inches
c) 280 cubic inches
d) 360 cubic inches
Answers
Answer:
The correct answers is D
D) 360 cubic inches
Step-by-step explanation:
We know that the Area of the base of the can is given by
A = 45 inch²
Initial height of the can = 12 inches
Fraction of height cut off = 1/3
Calculate the final height after cutting off:
Find 1/3 of 12 inches:
[tex]\frac{1}{3}\cdot12=4[/tex]
Subtract the answer from 12 to get final height:
Final height = 12- 4 = 8 inches
Can is a form of cylinder, so:
Volume = (Area)(height)

V
V
represent the volume of the cylinder.
Write an equation that expresses the relationship between the volume, height, and radius of this cylinder using c and V.
If the value of c is halved, what must happen to the value of the volume V?
Answers
Answer:
Relation between V and c is represented as:
[tex]V = \pi c^{3}[/tex]
When c is halved, V becomes [tex]\frac{1}{8}[/tex] of its initial value.
Step-by-step explanation:
Height of cylinder = Radius of cylinder = c
Volume of cylinder = V
As per formula:
[tex]V = \pi r^{2} h[/tex]
Where [tex]r[/tex] is the radius of cylinder and
[tex]h[/tex] is the height of cylinder
Putting [tex]r = h =c[/tex]
[tex]V = \pi c^{2} \times c\\\Rightarrow V = \pi c^{3} ......(1)[/tex]
The values of c is halved:
Using equation (1), New volume:
[tex]V' = \pi (\dfrac{c}{2})^3\\\Rightarrow \dfrac{1}{8} \pi c^{3}[/tex]
By equation (1), putting [tex]\pi \times c^{3} = V[/tex]
[tex]V' = \dfrac{1}{8} \times V[/tex]
So, when c is halved, V becomes [tex]\frac{1}{8}[/tex] of its initial value.

Answer:
8.94
Step-by-step explanation:
with a right triangle, you can use the Pythagorean Theorem, a^2 + b^2 = c^2
if you put in the values that you have, which are 8 and 4 into the equation, you get 8^2 + 4^2 = c^2
Now simplify, and you get 16 + 64 = c^2 which can then be further simplified to 80 = c^2
To get the value c all by itself, you have to square both sides. Square root of 80 becomes 8.94, and square root of c^2 becomes just a 'c'.
Therefore, you get 8.94 = c, meaning that the missing length (hypotenuse) is 8.94 units long.
