Answer:
3.5m is 500% of 70 cm and 70 cm is 20% of 3.5m.
Step-by-step explanation:
70 cm = 70cm/100= 0.7m
To solve the first problem use this equation:
3.5/0.7 *100 to get 500%
And to solve the second problem you use the same equation:
0.7/3.5*100 to get 20%
Hope this helps you.
You have to do trial and error with each of the choices to see which of those apply. They are points on the given function y=22x+32 that lie on point (x,y). Just substitute the x-and y values to the function.
a. (10,480) => x = 10, y = 480
y = 480 = 22(10) + 32
480 = 252 (does not apply)
b. (5,142) => x = 5, y = 142
y = 142= 22(5) + 32
142 = 142 (apply)
c. (8,208) => x = 8, y = 208
y = 208 = 22(8) + 32
208 = 208 (apply)
d. (7,154) => x = 7, y = 154
y = 154 = 22(7) + 32
154 = 186 (does not apply)
The answer is B and C.
Answer:
12i(36k)
Step-by-step explanation:
That's your answer when you use the distrubutive property you get your answer
Answer:
Yes.
Step-by-step explanation:
It satisfies our definition of a function. For every x, there is one and only one value of y.
Hope that helped.
Length = 2w +5
Area = l * w
63 = 2w +5 *w
63 = 2w² +5w
2w² +5w-63=0
(2w-9) (w+7)
2w-9 = 0 w+7=0
2w-9+9=0+9 w+7-7=0-7
2w =9 w= -7
2w/2=9/2
w= 4.5
Since the width can not negative the width is 4.5
Length = 2(4.5) + 5
Length =9 +5
Length = 14
Check
Area = 4.5 * 14
63 = 63
