Answer:
cocomelon . 3/5 - 4
Step-by-step explanation:
Diana's age=21 years
Carmen's age=x years
Andrew's age=2x years
21+x+2x=45
21+3x=45
3x=45-21
3x=24
x=24/3
x=8
2x8=16
Carmen is 8 years old and Andrew is 16 years old. Hoped that helps:)
Answer:
(a,b)
Step-by-step explanation:
simply we find the midpoint of AC and the midpoint of Bd by dividing over 2
Answer:
1.
ft 2.
yards 3.
units.
Step-by-step explanation:
Pythagorean's Theorem ![a^2 + b^2 = c^2](https://tex.z-dn.net/?f=a%5E2%20%2B%20b%5E2%20%3D%20c%5E2)
A and b are both side lengths, c is the hypotenuse.
7^2 + 5^2 = 74
sqrt(74) is the answer for 1.
30^2 - 5^2 = 875
Simplify the radical. sqrt(875) --> 5sqrt(35). The answer for three.
There's a rule in geometry that says a diagonal of a square is the same length as taking a side length times the square root of two. There's your answer for two.
Answer: l = 60 ft and w = 30 ft
P = 2(l + w)
180 = 2(l + w)
Let x = width of his yard
Let 2x = length of his yard
![180=2(2x+x)](https://tex.z-dn.net/?f=180%3D2%282x%2Bx%29)
![\frac{180}{2}=\frac{2(2x+x)}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B180%7D%7B2%7D%3D%5Cfrac%7B2%282x%2Bx%29%7D%7B2%7D)
![90=3x](https://tex.z-dn.net/?f=90%3D3x)
![\frac{90}{3} =\frac{3x}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B90%7D%7B3%7D%20%3D%5Cfrac%7B3x%7D%7B3%7D)
![x=30ft](https://tex.z-dn.net/?f=x%3D30ft)
l = 2x = 30(2) = 60 ft
Check:
180 = 2(l + w)
180 = 2(60 + 30)
180 = 2(90)
180 = 180
LS = RS
