can someone find the area of this/explain how they did it?
thanks ! it means a lot. no links pls !!!
Answers
Answer: 1914 sq. ft
Step-by-step explanation:
area of circle= pi x radius squared
=3.14 x 10^2
=3.14x100
=314
area triangle= 1/2 base x height
=1/2(20x60)
= 1/2(1200)
= 600
area of rectangle= length x width
=50 x 20
= 1000
add the totals 1000 + 600 + 314=1914 sq. ft.

The farmer walks by the pen with the chickens and pigs. He counts 18 heads and 50 feet. How many of each, chicken and pigs, are there?
Answers
Answer:
chickens = 11
pigs = 7
Step-by-step explanation:
this would be solved using simultaneous equation
let c = chicken .
p = pigs
A normal pig and chicken both have 1 head. thus :
c + p = 18 equation 1
A normal pig has 4 legs and a normal chicken has 2 legs. Thus
2c + 4p = 50 equation 2
multiply equation 1 by 2
2c + 2p = 36 equation 3
subtract equation 3 from 2
2p = 14
p = 7
substitute for p in equation 1
c + 7 = 18
c = 11

Step-by-step explanation:
In a 30 60 90 degree triangle, the hypotenuse is always double the shorter leg. Hope this helps! :)
The hypotenuse of the 30-60-90 triangle whose shorter leg is 8 m is: 16 m.
What is the 30-60-90 Triangle?The 30-60-90 triangle is a right triangle whose hypotenuse length is always twice the length of the its shorter leg.
Given a 30-60-90 triangle whose shorter leg is 8 m long, therefore:
Hypotenuse of the 30-60-90 triangle = 2(length of the shorter leg)
Hypotenuse of the 30-60-90 triangle = 2(8)
Hypotenuse of the 30-60-90 triangle = 16 m.

A function assigns the values. The value of (5r+1/5)² when the value of r is 0 equals 0.04.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
Given the function g(r)=(5r+1/5)², therefore, the value of the function when r=0 will be,
g(r) = (5r+1/5)²
g(0) = [5(0)+1/5]²
g(0) = (1/5)²
g(0) = 1/25
g(0)=0.04
Hence, the value of (5r+1/5)² when the value of r is 0 equals 0.04.

A function f(x) has x-intercepts of -3 and -5. What is the constant term in the function?
f(x) = x2 + 8x +
Answers
Answer:
15
Step-by-step explanation:
The x-intercepts -3 and -5 are also "roots" of the polynomial. The corresponding factors are (x + 3) and (x + 5). Multiply the constants together: 3*5 = 15. This is the desired constant term.
Note that your f(x) = x2 + 8x + should be written f(x) = x^2 + 8x + ... The " ^ " denotes exponentiation.
Check: Multiply (x + 3) and (x + 5) together and compare the result to the given polynomial with constant term 15:
f(x) = (x + 3)(x + 5) = x^2 + 3x + 5x + 15 = x^2 + 8x + 15. This matches!

A third candle, in the shape of a right circular cone, has a volume of 16 cubic inches and a radius of 1.5 inches. What is the height, in inches, of the candle? Round your answer to the nearest inch.
Answers
Given:
Volume of a right circular cone = 16 cubic inches
Radius of the cone = 1.5 inches.
To find:
The height of the cone.
Solution:
The volume of a cone is:
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Where, r is the radius and h is the height of the cone.
Putting [tex]V=16,r=1.5,\pi=3.14[/tex] in the above formula.
[tex]16=\dfrac{1}{3}(3.14)(1.5)^2h[/tex]
[tex]48=(3.14)(2.25)h[/tex]
[tex]48=7.065h[/tex]
Divide both sides by 7.065.
[tex]\dfrac{48}{7.065}=h[/tex]
[tex]6.794=h[/tex]
[tex]h\approx 7[/tex]
Therefore, the height of the cone is 7 inches.
