Answer:
g = 10.82
_______ or 5.694736842105263
-1.9
Step-by-step explanation:
- 1.6g - 0.3g = 6.46 + 4.36
-1.9g = 10.82
g = 10.82
_____
-1.9
1.6 miles - 1.1 miles = 0.5 miles
8 minutes - 2 minutes = 6 minutes
She traveled 0.5 miles in 6 minutes.
1 hour = 60 minutes.
60 minutes / 6 minutes = 10
0.5 x 10 = 5
She is walking 5 miles per hour.
Full rotation or full turn
Answer:
Step-by-step explanation:
7/3 * 2/3
14/3 * 1/3
Answer:
Step-by-step explanation:
Let the number of ounces of
A = x
B = y
A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?
Our system of equations is given as
x + y = 90.... Equation 1
x = 90 - y
40% × x + 55% × y = 45% × 90 ounces
0.4x + 0.55y = 40.5....Equation 2
We substitute 90 - y for x in Equation 2
