=> cot∅ = 2x/11x = b/p
Pyhthagoras Theorem :-
=> h² = (2x)² + (11x)²
=> h² = 4x² + 121x²
=> h² = 125x²
=> h = √ 25 × 5 x
=> h = 5√5 x

Because when doing area for triangles its
base × height ÷ 2 so for 1 triangle it would be 5 × 4 = 20 then ÷ by 2 so 20 ÷ 2 = 10 Since there are 4 triangles we will have to add 10 4 times and then for the square it's easily just 4 × 4 = 16
so it would come out to 16 + 10 + 10 + 10 + 10 =
The circumference of a circle is double the perimeter of square having area 484 meter square . what is the area of the circle.
Answer:
وتؤوثتيمسوثاسز لا لا لا وا
Answer:
616 sq. m
Step-by-step explanation:
The area of a square = 484
(Side)2 = 484
side of a square = 22 m
According to the question,
circumference of a circle = perimeter of a square
2∏r = 4 × 22
r = 88 × 7/22 × 1/2
r = 14 m
Area of a circle = ∏r2 = 22/7 × 142 = 616 sq. m
The circumference of a circle is 6 2/7 miles. What is the area of the circle in square miles? ( Use 22/7 for pi.)
Answer:
solution given:
circumference of circle=6 2/7=44/7miles
2πr=44/7 miles
r=44/7×7/44=1 miles
now
area of circle=πr²=22/7×1²=22/7 =3 1/7 miles ²

What expression is equivalent to m(n+p)
Answer:
mn + mp
Step-by-step explanation:

The equivalent expression for the algebra m(n+p) is mn + mp.
What are equivalent expressions?Equivalent expressions are similar expressions that when being solved provide the same solution. Equivalent expressions are used widely in the expansion of algebraic equations.
From the given information, we have:
= m(n + p)
To determine the equivalent expression for the above algebraic equation, we need to expand the bracket as follows:
= m(n) + m(p)
= mn + mp

Classify a triangle whose side lengths are 8, 16, and 18
A. Right Triangle
B. Acute Triangle
C. Obtuse Triangle
D. Isosceles Triangle
Answer:
Obtuse triangle
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.
In right angle triangle, one angle is 90°. The square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.
An acute triangle is a triangle with acute angles (less than 90°). The square of the longest side is less than the sum of the square of the two sides.
An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles (less than 90°). The square of the longest side is larger than the sum of the square of the two sides.
An isosceles triangle is a triangle with two equal sides.
Given a triangle whose side lengths are 8, 16, and 18, the longest side is 18.
Since no two sides are the same hence it is not an isosceles triangle.
Also, 18² > 16² + 8²; therefore this is an obtuse triangle
Jersey village population in 1950 was 10,173. The population increases by 8.9% every 10 years. Predict the population in 2020
Answer:
Future Value= 18,478 people
Step-by-step explanation:
eGiving the following information:
Present value (PV)= 10,173
Growth rate (g)= 0.089 every 10 years
Number of periods (n)= 7
To calculate the population in 2020, we need to use the following formula:
FV= PV*(1 + g)^n
FV= 10,173*(1.089^7)
FV= 18,478 people

How do you find the mean, median, mode, and range of a set of numbers?
Answer:
You find the mean by adding all the numbers together then divide the sum of that by the amount of numbers there are. You find the median by looking at the middle number. You find the mode by looking at the most used number. You find the range by subtracting the highest and lowest numbers.
Step-by-step explanation:
say you have these numbers ( 8, 7, 17, 12, 0, 9, 11, 5, 8)
Mean:
8 + 7 + 12 + 17 + 0 + 9 + 11 + 5 + 8 = 77
77 ÷ 9 = 8.5
Median: 0
Mode: 8
Range: 17 - 0 = 17
Answer:
median is the middle number
but if the are two numbers in middle u add those two n divide by 2
range is the biggest number subtract lowest number
mean is total average divide by the number of data
mode is the number that appears many times

Malik got a 200 cafe gift on January 1. He always orders decaf mochas which cost 5 each. At the end of January, maliks gift card has 125 left. Write an equation with x as your variable.
Answer:
200 - 5x = 125
Step-by-step explanation:
Let the number of orders made by Malik in the month of January = x
Each order costs = $5
Total cost of decaf mochas in one order = $5x
Malik had cake gift on 1st of January = $200
Amount of money left with Malik at the end of January = $125
Therefore, equation representing this situation will be,
200 - 5x = 125

Answer:
Surface Area of right cone

[tex]440 = \pi *7*(7+\sqrt{h^2+7^2})\\\\440 = 7\pi (7 + \sqrt{h^2+7^2})\\\\\frac{440}{7\pi } = 7 + \sqrt{h^2+49}\\\\\frac{440}{7\pi } - 7 = \sqrt{h^2+49}\\\\\frac{440-49\pi}{7\pi} =\sqrt{h^2+49}\\\\[/tex]
[tex]\frac{286.062}{21.99} =\sqrt{h^2+49}\\\\13.0087= \sqrt{h^2+49}\\\\(13.0087)^2 = (\sqrt{h^2+49})^2\\\\169.227 = h^2 +49\\\\169.227 - 49 =h^2\\\\120.227 = h^2\\\\h = \sqrt{120.227} = 10.96in[/tex]

Answer:
$65
Step-by-step explanation:
x is the number of items sold, and y is the profit, so we need to calculate
y = 35x - 250
where x=9
y = 35*9 - 250 = 315 - 250 = 65
So the total profit is 65 dollars
