Answer:
B) C and G
Step-by-step explanation:
The radius is equal to 1/2 the diameter
r = 1/2 d
G has a diameter of 45
1/2 (45) = 22.5
C and G are the same
Answer:
7x - 8y = 37
Explanation:
y+2 = ⅞(x-3) (distribute ⅞ -- x times 7/8, -3 times 7/8)
y+2 = ⅞x - 21/8 (subtract ⅞x from both sides)
y+2-⅞x = -21/8 (subtract 2 from both sides)
y-⅞x = -37/8 <--- result of -21/8 - 2
Multiply both sides by 8 to get ride of fractions
8y - 7x = -37 (rearrange)
-7x + 8y = -37
It's better to have a positive coefficient for x if you can. So multiply both sides by -1. That just means changing the sign of every term on both sides, you get
7x - 8y = 37
La función que a cada número le asocia su mitad es: f(x)= x/2
Explicación:
La mitad de una cantidad consiste en dividir el total en dos partes iguales, por lo tanto, la función debe representar una división entre el total y 2. Sea x el total, la función sería:
f(x)= x/2
Ejemplos:
La mitad de 20: f(20)= 20/2 = 10
La mitad de 8: f(8)= 8/2 = 4
La mitad de 100: f(100)= 100/2 = 50
La mitad de 2354: f(2354)= 2354/2 =1177
Tanα=y/x
y=xtanα, we are told that x=25ft and α=30°
y=25tan30° ft
y≈14.43 ft (to nearest hundredth of a foot)
Since their home is 20 feet from the base of the tree, it poses no risk right now.
A ratio is comparison between two number such as
I have three dogs and two cats the ratio of cats to dogs is 2:3 or what is the ratio of cats to total pets which is 2;5
