I have 7 cups of yogurt give my sister 3 3/5 cup how yogurt remains?
Answers
Answer:
3 2/5 cups remaining
Step-by-step explanation:
To subtract fractions, they need a common denominator. I am using 5.
7 is equal to 35/5. Make 3-3/5 into an improper fraction of 18/5.
Now subtract: 35 - 18 = 17. There is 17/5 remaining.
Make it into a mixed number and you will get 3 2/5 remaining.

Answer: Choice B) -infinity < x < infinity
==========================================================
Explanation:
The parabola goes on forever to the left and to the right. We can plug in any x value without worrying about something as a division by zero error. So any real number will work.
Writing -infinity < x < infinity refers to the entire number line, which is the set of all real numbers.

what is the range of the data below 6.5,7.6,9.1,2.4,8.8
Answers
Answer:
the range would be 6.7 or if you want it to be rounded up, it would be 7.
Step-by-step explanation:
you subtract the highest number by the lowest number. 9.1-2.4= 6.7 or if you need it to be rounded, 7.
The range of the data set given is 6.7.
What is range in statistics?In statistics, the range of a set of data is the difference between the largest and smallest values, the result of subtracting the sample maximum and minimum. It is expressed in the same units as the data.
Given is a data set, we need to find the range of the data set,
S = 6.5, 7.6, 9.1, 2.4, 8.8
The range = max value - min value
= 9.1 - 2.4 = 6.7
Hence, the range of the data set given is 6.7.

Step-by-step explanation:
Answer:
Step-by-step explanation:
I assume that they want the value of a when the solution exists.
2(ax+3y)+2x-6y=2(-5)+10
2ax+6y+2x-6y=-10+10
2ax+2x=0
ax+x=0
ax=-x
a=-1
You could then solve for x and y if you wanted x=5 and y=0

Answer: D
Step-by-step explanation: you just got coconut malled send this to a friend to totally coconut mall them (D is correct)
Answer:
d, 40% !
Step-by-step explanation:
this one, you can use long division ! since the faction of apple to all fruit is 6/15, you divide 6 by 15. you would get the decimal 0.4
in order to make that a percentage, you'd just move the decimal two places to the right, then add a % !! so it's 40% !!

A large mixing tank initially contains 1000 gallons of water in which 40 pounds of salt have been dissolved. Another brine solution is pumped into the tank at the rate of 5 gallons per minute, and the resulting mixture is pumped out at the same rate. The concentration of the incoming brine solution is 3 pounds of salt per gallon. If img represents the amount of salt in the tank at time t, the correct differential equation for A is:______.
A) dA/dT=3--.005A
B) dA/dT=5--.05A
C) dA/dT=15--.005A
D) dA/dT=3--.05A
E) dA/dT=15+.05A
Answers
Answer:
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer
Step-by-step explanation:
Given the data in the question;
If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is?
dA/dt = rate in - rate out
first we determine the rate in and rate out;
rate in = 3pound/gallon × 5gallons/min = 15 pound/min
rate out = A pounds/1000gallons × 5gallons/min = 5Ag/1000pounds/min
= 0.005A pounds/min
so we substitute
dA/dt = rate in - rate out
dA/dt = 15 - 0.005A
Therefore, If A(t) represents the amount of salt in the tank at time t, the correct differential equation for A is is dA/dt = 15 - 0.005A
Option C) dA/dt = 15 - 0.005A is the correction Answer
