Well if her speed is 55 miles per hour
1 hour= 55 miles
? hour= 192 miles
You can divide by 55 and get
3.5 ( I rounded the number)
Hope this helps?
Answer:114 red marbles
Step-by-step explanation:
19r + 1b = 20
120/20=6 black marbles
19 x 6 = 114 red marbles
2 consecutive odd positive integers....x and x + 2
x^2 + (x + 2)^2 = 130
x^2 + (x + 2)(x + 2) = 130
x^2 + x^2 + 4x + 4 = 130
2x^2 + 4x + 4 = 130
2x^2 + 4x + 4 - 130 = 0
2x^2 + 4x - 126 = 0
2(x^2 + 2x - 63) = 0
2(x - 7)(x + 9) = 0
x - 7 = 0
x = 7
x + 9 = 0
x = -9 (cant be this one because it is negative
so x = 7...and x + 2 = 7 + 2 = 9......ur 2 numbers are 7 and 9
Answer:
Graph B
Step-by-step explanation:
Remember that for a function to have an inverse, the function must be 1-to-1. The two functions must also be symmetrical about the line y=x, which is apparent in the second graph.
Given:
Amount of flour in a bin = 30 cups
Flour required for each signature cake = 
cups
To find:
The correct equation and graph for the given situation.
Solution:
Let F be the amount of flour in the bin and c be the number of signature cakes.
Flour required for each signature cake = cups
Flour required for each signature cake = 
cups
Flour required for c signature cakes = 
cups
Amount of flour in a bin is 30 cups and it is reduced by 1.5c cups. So, the amount of flour in the bin is:
At 
, we get
At 
, we get
Therefore, the required equation is and the 4th graph is correct.
