Step-by-step explanation:
In Δ AFB,
∠AFB + ∠ABF + ∠A = 180 {Angle sum property of triangle}
90 + 48 + ∠1 = 180
138 + ∠1 = 180
∠1 = 180 - 138
∠1 = 42°
FC // ED and FD is transversal
So, ∠CFD ≅∠EDF {Alternate interior angles are congruent}
∠2 = 39°
In ΔFCD,
∠2 + ∠3 + ∠FCD = 180
39 + ∠3 + 90 = 180
129 +∠3 = 180
∠3 = 180- 129
∠3 = 51°

The formula for the volume of a cone is V=13πr2h,V=\frac{1}{3}\pi r^2 h,V=31πr2h, where r is the radius of the cone and h is the height of the cone. Rewrite the formula to solve for the positive value of rin terms of h and V.
Answers
Answer:
r = √3V/√πh
Step-by-step explanation:
V = 1/3πr²h
where,
V = volume of the cone
r = radius of the cone and
h = height of the cone.
Rewrite the formula to solve for the positive value of r in terms of h and V.
V = 1/3πr²h
V = 1/3 * π * r² * h
r² = V ÷ 1/3 * π * h
r² = V ÷ πh/3
r² = V × 3/πh
r² = 3V / πh
find the square root of both sides
√r² = √3V / πh
r = √3V/πh
Also written as
r = √3V/√πh

The horizontal shift depends on the value of h . When h>0 , the horizontal shift is described as: g(x)=f(x+h) g ( x ) = f ( x + h ) - The graph is shifted to the left h units. g(x)=f(x−h) g ( x ) = f ( x - h ) - The graph is shifted to the right h units.

Step-by-step explanation:
A linear pair of angles sum to 180° , then
3x + 10 + 4x - 5 = 180
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25
Then
3x + 10 = 3(25) + 10 = 75 + 10 = 85°
4x - 5 = 4(25) - 5 = 100 - 5 = 95°
------------------------------------------------------------
3x - 3 + 5x + 7 = 180
8x + 4 = 180 ( subtract 4 from both sides )
8x = 176 ( divide both sides by 8 )
x = 22
Then
3x - 3 = 3(22) - 3 = 66 - 3 = 63°
5x + 7 = 5(22) + 7 = 110 + 7 = 117°

Chloe wants to make a scrapbook with old family photos. An online scrapbooking company charges $45 plus $1 per page. Meanwhile, a family friend is willing to make a scrapbook for $9 plus $4 per page. For a certain number of pages, the prices would be equal. How many pages would that be? How much would Chloe be charged?
Answers
Answer:
The prices are equal when it's 12 pages. For 12 pages, she'd be charged $57
Step-by-step explanation:
x = PER page
y = total
Online scrapbooking equation:
y = 45 + x
Family friend equation:
y = 9 + 4x
Where prices (y) would be equal:
y = 45 + x (Multiply this by -4)
y = 9 + 4x
y = 9 + 4x
-4y = -180 - 4x
-3y = -171
y = 57
y = 45 + x
-y = -9 - 4x
0 = 36 - 3x
3x = 36
x = 12

3(12+x) = 96
Divide by 3
3(12+x)/3 = 96/3

Answers
y=7. x= 13
Answer:
x = 13 , y = 7
Step-by-step explanation:
x + 2y = 27 => x = 27 - 2y ---------( 1 )
2x - y = 19 ------------ ( 2 )
Substitute ( 1 ) in ( 2 ) :
2x - y = 19
2(27 - 2y) - y = 19
54 - 4y - y = 19
-5y = 19 - 54
-5y = -35
y = 7
Substitute y = 7 in ( 1 ) :
x = 27 - 2y
x = 27 - 2( 7 )
x = 27 - 14
x = 13

The elimination method is ideal for solving this system of equations. By which number must you multiply the second equation to eliminate the y-variable, and what is the solution for this system?
x + 3y = 42
2x=y= 14
A.) Multiply the second equation by-3. The solution is x = 12, y=9.
B.) Multiply the second equation by -2. The solution is = 12. y=10.
C.) Multiply the second equation by 2. The solution is x= 15, y=9.
D.) Multiply the second equation by 3. The solution is x= 12 y= 10.
Answers
Answer:
D.
Step-by-step explanation:
In order to eliminate, the numbers must eliminate. If the second equation is multiplied by 3, then the 3 and the -3 can be eliminated. Since it is multiple choice, we can plug in x = 12 and y = 10 to see if they are correct. 12 + 30 = 42 and 24 - 10 = 14, so D is correct.
