Answer: The answer is A
Step-by-step explanation:
Answer:
The answer is 34.6, or A.
Step-by-step explanation:
The formula for area is pi*r*r. This means that you will have to take the area, or A, and do this: [tex]\sqrt{\frac{a}{pi} }[/tex]. That would be that radius, so then multiply that by 2*pi, and that would give an answer of approximately 34.6.

Mathematically;
we have a structure like an arc of a circle. It is the length of this arc we want to calculate.
The formula for the length of an arc is;
theta/360 * 2 * pi * r
r is the radius which in this case is 50 cm
We have ;
115/360 * 2 * 3.1412 * 50 = 100 cm approximately

,
then a = and b = .
Answers
Answer:
a = 0, b = -15
Step-by-step explanation:
Given the following complex number;
x1 = 3(cosπ+isinπ)
x2 = 5(cosπ/2 - isinπ/2)
x1x2 = 15(cosπcosπ/2 - icosπsinπ/2+isinπcosπ/2 -i²sinπsinπ/2)
x1x2 = 15(0 - i(-1)+0 -0)
x1x2 = 15(-i)
x1x2 = -15i
x1x2 = 0-15i
Since
0 - 15i = a+ bi
Compare
a = 0
-15- = bi
b = -15
Hence a = 0, b = -15
20 out of 800 products were found to be defective. At the same rate, how many defective parts will be found in 40,000 products? There would be Blank 1 defective parts out of 40000.
Answers
Answer: 1,000 products
Step-by-step explanation:
If 20 out of 800 products are found to be defective, the percentage of defective products would be:
= 20 / 800
= 2.5%
At this same rate of 2.5%, if there are 40,000 products instead of 800, the number of defective products would be:
= 2.5% * 40,000
= 1,000 products

What is the equation of the line that passes through the point (- 1, 5) and is parallel to the line y = - 3x + 5
Answers
Answer:
y - 5 = -3(x + 1)Step-by-step explanation:
Parallel lines has the same slope.
The equation of a line that passing through point (x₁, y₁) with a slope of m is:
y - y₁ = m(x - x₁)
m = -3
(-1, 5) ⇒ x₁ = -1, y₁ = 5
Therefore the equation:
y - 5 = -3(x + 1)

The triangle is an isosceles right triangle, and the true statements about the triangle are
The triangle must be an isosceles triangle. The triangle must be a right triangle. The triangle must contain an angle measuring 45°How to determine the true statements?The given parameters are:
Angle = 90 degrees
Two side lengths = 5 cm
Given that one of the angles is 90 degrees, then it means that the triangle is a right triangle.
Also since two sides are equal, then the triangle is an isosceles triangle, and the other angles are 45 degrees each
Hence, the true statements about the triangle are (a), (c) and (e)

A person invests 3500 dollars in a bank. The bank pays 6.25% interest compounded annually. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 11100 dollars?
Answers
The duration of time period required is 2.4 years.
What is a compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.
Given that, A person invests 3500 dollars in a bank. The bank pays 6.25% interest compounded annually.
A = P(1+r/100)ⁿ
n = time
A = amount
P = principal
11100 = 3500(1+0.0625)ⁿ
3.171 = (1.0625)ⁿ
Taking log to both sides,
log(3.171) = nlog(1.0625)
n = 2.40
Hence, the required time is 2.4 years.

A trader sold a radio set for 72.00 making a profit of 8% .Find , correct to the nearest ghana cedis ,the cost price for the radio set .
Answers
Given:
The selling price of a ratio set = 72.00
Profit percent = 8%
To find:
The cost price for the radio set.
Solution:
Let x be the cost price for the radio set.
Radio set is sold at 8% profit.
[tex]\text{Selling price}=x+\dfrac{8}{100}x[/tex]
[tex]\text{Selling price}=x+0.08x[/tex]
[tex]\text{Selling price}=1.08x[/tex]
The selling price of a ratio set is 72.00.
[tex]72=1.08x[/tex]
[tex]\dfrac{72}{1.08}=x[/tex]
[tex]x=66.666...[/tex]
[tex]x\approx 67[/tex]
Therefore, the cost price for the radio set is 67.

Step-by-step explanation:
question 5:
tan45=x/13
multiply both sides by 13 to get x by its self.
end up with 13×tan45 so put that in the calculator to get x
then you do cos45= 13/y
multiply by y on both sides.
end up with y×cos45=13
divide the cos45 by both sides
put 13/cos45 to get y
question 6:
sin30=4/x
multiply x on both sides
end with x×sin30 =4
divide sin30 on both sides
put 4/sin30 in a calculator to get x
