Answer:
27.27cm²
Step-by-step explanation:
∅=125° r=5m
A=∅/360×πr²
A=125/360×3.142×5²
A=27.27cm²
SHORT ANSWER: 84cm
Let width = w
Let length = w + 5
The area of a rectangle is found by multiplying its width by length and the problem states that the area is 84 cm2.
(Width)(Length) = 84
(w)(w + 5) = 84
w2 + 5w = 84
w2 + 5w - 84 = 0
(w + 12)(w -7) = 0
w + 12 = 0
w = -12
The width of a rectangle can't be NEGATIVE!!! Forget about that!
w - 7 = 0
w = 7
Now go back to naming the variables and replace the w with 7.
Length = w + 5 = 7 + 5 = 12
Width is 7 cm. Length is 12 cm.
Check it. Is 7 x 12 = 84? Yes.
Answer:
Step-by-step explanation:
Bag A contains 9(5/9) pounds of coffee
Bag B contains 9(2/3) pounds of coffee
Which bag contains less coffee?
( 2/3) is the same as (6/9)
Now that the denominators are the same, if we compare the numerators, 5 is less than 6 (5 parts of 9 is less than 6 parts of 9)
Bag A contains less coffee than bag B
9(5/9) < 9(2/3)
A) 0.73
B) 21.93
C) 7.67

Answer:
y = 9x -1
Step-by-step explanation:
The slope is 9 and the y intercept ( where x is zero) is -1
We can use the slope intercept form of the equation is
y = mx+b where m is the slope and b is the y intercept
y = 9x -1
