Answer:
6/11 divided by 2 2/3 (=9/44)
2/7 divided by 4/5 (=5/14 or 15/42 scaled up)
1 6/7 divided by 3 (= 13/21 or 26/42 scaled up)
3/10 divided by 1/8 (=2 2/5)
Step-by-step explanation:
You cannot divide a fraction by a fraction. Instead, multiply by the reciprocal ( flip it)
2/7 divided by 4/5= 2/7 x 5/4
Multiply straight across the top, 2x5= 10
10 is the numerator
Now multiply straight across the bottom.
7x4= 28
28 is the denominator.
10/28 is the answer to this problem, however it can be simplified. Both 10 and 28 are divisible by 2. This simplifies to 5/14.
For mixed numbers, you first have to make them improper fractions.
Ex: 2 2/3
Take the denominator (3) multiply it by the whole number (2) and add the numerator (2)
3x2=6 (now add the remaining 2 from the numerator) 6+2= 8. 8 is your new numerator and you will keep the existing denominator of 3 making the improper fraction 8/3.
Answer:
Not if store closes at 5pm. The time store closes isn’t mentioned.
Step-by-step explanation:
If it takes her 35 minutes to drive to the hardware store, she would arrive at 5:05 (4:30+:35 minutes)
From an analytical point of view, a quadratic equation has no (real) solution if the discriminant is negative.
In fact, the equation for the solution involves the quantity 
, where a,b and c are the coefficient of the equation 
.
Since we can't compute the square roots of negative numbers using real numbers, if 
the equation has no solution.
From a geometric point of view, the solutions of an equation are the points where the graph of the equation intersects the x axis. So, if a parabola (i.e. the graph of a quadratic polynomial) has no solutions, it means that its graph never intersercts the x axis.
The correct question is;
Ellen has a bag with 3 red marbles and 2 blue marbles in it. she is going to randomly draw a marble from the bag 300 times, putting the marble back in the bag after each draw. what is the best prediction for the number of times that ellen will draw a blue marble?
Answer:
120 times
Step-by-step explanation:
We are given;
Red Marbles = 3
Blue Marbles = 2
Thus;
Total Marbles = 3 + 2 = 5
Probability of of Blue Marbles;
P(B) = 2/5
Total number of Draws = 300
Hence, best prediction for the number of times that ellen will draw a blue marble = 300 x (2/5)
= 120
Thus, prediction is 120 Times that Ellen will Draw Blue Marbles
