Pls Help! This is due today! Find the value of x:
Answer:
x = 23
Step-by-step explanation:
the sum of all interior angles of triangle is 180 dehrees.
top angle = 180-100 = 80 degrees
80 + 51 + (2x+3) = 180
2x+3 = 49
2x = 46
x = 23

Find the equation of the line through the points (-8,3) and (-4,5).
Answer:
[tex]2y - x = 14[/tex]
Step-by-step explanation:
Given
[tex](x_1,y_1) = (-8,3)[/tex]
[tex](x_2,y_2) = (-4,5)[/tex]
Required
The line equation
First, calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{5 - 3}{-4 - (-8)}[/tex]
[tex]m = \frac{2}{4}[/tex]
[tex]m = \frac{1}{2}[/tex]
The equation is then calculated as:
[tex]y = m(x - x_1) + y_1[/tex]
[tex]y = \frac{1}{2}(x - (-8)) +3[/tex]
[tex]y = \frac{1}{2}(x +8) +3[/tex]
Open bracket
[tex]y = \frac{1}{2}x +4 +3[/tex]
[tex]y = \frac{1}{2}x +7[/tex]
Multiply through by 2
[tex]2y = x + 14[/tex]
[tex]2y - x = 14[/tex]
2t + 4(4 + 10t)
Simplify the expression
Answer:
=42t+16
Step-by-step explanation:
=2t+(4)(4)+(4)(10t)
=2t+16+40t
=2t+16+40t
=(2t+40t)+(16)
=42t+16
Simplify the expression
2t + 4(4 + 10t)
Simplifying
y = 2t4 + -10t2 + 13
Reorder the terms:
y = 13 + -10t2 + 2t4
Solving
Solving for variy = 13 + -10t2 + 2t4
able 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 13 + -10t2 + 2t4
Hence the information I've given you, we can now state that the answer is
42 t + 16
Find the volume of a pyramid with a square base, where the perimeter of the base is 7.4 ft and the height of the pyramid is 8.1 ft. Round your answer to the nearest tenth of a cubic foot.
9514 1404 393
Answer:
9.2 ft³
Step-by-step explanation:
The side length of the square base is 1/4 of the perimeter, so is ...
s = P/4 = (7.4 ft)/4 = 1.85 ft
The area of the base is the square of this, or ...
A = s² = (1.85 ft)² = 3.4225 ft²
The volume of the pyramid is given by ...
V = 1/3Bh = (1/3)(3.4225 ft²)(8.1 ft) = 9.24075 ft²
The volume of the pyramid is about 9.2 cubic feet.
