Find the area of the composite figure.
Round answer to the nearest tenths place
Answers
Answer:
The area of the composite figure = 65.1 in.²
Step-by-step explanation:
The given figure is formed from
A triangle of base 8 inches and height (14 - r) inches where r is the radius of the semi-circleA semi-circle of diameter 8 inchesLet us find the areas of the triangle and the semi-circle, then add them up
∵ The diameter of the semi-circle is 8 inches
→ The radius is half the diameter
∴ The radius of the semi-circle = 8 ÷ 2 = 4 inches
→ The area of the semi-circle = [tex]\frac{1}{2}[/tex] πr²
∴ The area of the semi-circle = [tex]\frac{1}{2}[/tex] π(4)²
∴ The area of the semi-circle = [tex]\frac{1}{2}[/tex] π(16)
∴ The area of the semi-circle = 8π in.²
∵ The height of the triangle is (14 - r) in.
∵ r = 4 in.
∴ The height of the triangle = 14 - 4 = 10 in.
→ The area of the triangle = [tex]\frac{1}{2}[/tex] × base × height
∵ The base of the triangle = 8 in.
∴ The area of the triangle = [tex]\frac{1}{2}[/tex] × 8 × 10
∴ The area of the triangle = 40 in.²
→ Add the two areas to find the area of the figure
∵ The area of the composite figure = 8π + 40
∴ The area of the composite figure = 65.13274123 in.²
→ Round it to the nearest tenths place (one decimal place)
∴ The area of the composite figure = 65.1 in.²

Two uniformly charged, infinite, nonconducting planes are parallel to a yz plane and positioned at x = -50 cm and x = +50 cm. The charge densities on the planes are -50 nC/m² and +25 nC/m², respectively. What is the magnitude of the potential difference between the origin and the point on the x axis at x = +80 cm? (Hint:Use Gauss’ law.)
Answer:
ΔV = 2520 V
Step-by-step explanation:
We are given;
Charge density 1; σ1 = -50 nC/m² = -50 × 10^(-9) nC/m²
Charge density 2; σ2 = +25 nC/m² = +25 × 10^(-9) nC/m²
Now, formula for electric field strength is;
E = -(½ε)(|σ1| ± |σ2|)
ε is vacuum permittivity with a constant value as 8.85 × 10^(−12) C²/N.m²
|σ1| and |σ2| means we are taking the absolute values and would therefore not use the negative sign attached to them.
Now, in between x = 0 cm(0 m) and 50 cm (0.5 m), electric field generated by both charge densities would be in the same direction and thus;
E_in = -(½ε)(|σ1| + |σ2|)
E_in = -(½ × 8.85 × 10^(−12)) × [(50 × 10^(-9)) + (25 × 10^(-9))]
E_in = -4200 V/m
In contrast, when x ≥ 50 cm (0.5 m), electric field generated by both charge densities would be in opposite directions and thus;
E_out = -(½ε)(|σ1| - |σ2|)
E_out = -(½ × 8.85 × 10^(−12)) × [(50 × 10^(-9)) - (25 × 10^(-9))]
E_out = 1400 V/m
The magnitude of the potential difference from the origin to x = 80 cm(0.8 m) is calculated as attached;
From the attachment, we see that;
ΔV = 2520 V
Mercury travels about 107,100 miles per hour as it revolves around the Sun. How far does Mercury travel in 15 seconds?

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
WE have given that Mercury travels about 107,100 miles per hour as it revolves around the Sun.
Miles travelled in 1h = 107,100
Miles travelled in 1 sec = 107,100 /3600
= 29.75
Miles travelled in 15 seconds = 29.75 × 15
= 446.25 miles
Therefore, Mercury will travel 446.25 miles in 15 seconds as it revolves around the Sun.

write the equation of a line parallel to the line with an equation y=8x+6 and passes through the point (3,9)
Answers
Answer:
y = 8x - 15
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 8x + 6 ← is in slope- intercept form
with slope m = 8
Parallel lines have equal slopes, thus
y = 8x + c ← is the partial equation
To find c substitute (3, 9) into the partial equation
9 = 24 + c ⇒ c = 9 - 24 = - 15
y = 8x - 15 ← equation of parallel line

Complete Question
Joe needs to transfer 28 quarts of oil into gallons containers joe calculated that he needs 112 containers but he made a mistake in his calculations identify and correct his error
Joe's error:
28 quarts × 4 quarts/ 1 gallon
= 28 quarts/1 × 4 quarts/ 1 gallon
= (28 × 4)/ ( 1 × 1) = 112 gallons
Answer:
7 gallons is the correct answer
Joe needs to transfer 28 quarts of oil into 7 gallons
Step-by-step explanation:
Joe's error:
28 quarts × 4 quarts/ 1 gallon
= 28 quarts/1 × 4 quarts/ 1 gallon
= (28 × 4)/ ( 1 × 1) = 112 gallons
Correcting Joe's error, we have:
4 quarts = 1 gallon
28 quarts = x
Cross Multiply
4 quarts × x = 28 quarts × 1 gallon
x = 28 quarts × 1 gallon/ 4 quarts
x = 7 gallons
= 28 quarts/x gallons × 1 gallon/4 quarts
= (28 × x)/ ( 1 /4) = 7 gallons
Therefore, Joe needs to transfer 28 quarts of oil into 7 gallons

Angle S is 32.3 degrees and angle R is 96.5 degrees. Triangle A D C is similar to triangle R T S because Angle A is congruent to angle R, Angle C is congruent to angle S, and Angle D is congruent to angle T. Triangle A D C is similar to triangle R T S because Angle A is similar to angle R, Angle C is similar to angle S, and Angle D is similar to angle T. Triangle A D C is not similar to Triangle R T S because Angle D is not congruent to Angle S. Triangle A D C is not similar to Triangle R T S because C D less than S T, D A less than T R, and C A less than S R.

Answers
Answer:
x = - y-12/5+4k
Step-by-step explanation:
Solve 12-5x-4kx=y for x
12-5x-4kx = y for x
substract 12 from both side
-5x-4kx = y-12
Factor of -5x-4kx = -x(5+4k)
-x(5+4k) = y-12
Solve for x
-x = y-12/(5+4k)
Therefore x = - y-12/5+4k
