Answer:
24 purple jelly beans
Step-by-step explanation:
We are told in the question that;
Lucas had a mix of red and purple jelly beans. There were 2 red jelly beans for every 3 purple jelly beans.
The results in a ratio
2:3
Where 2 represented red jelly beans
3 represented purple jelly beans
Total number of jelly beans = 40 jelly beans.
The number of purple jelly beans that we have =
3/( 2 + 3) × 40
= 3/5 × 40
= 3 × 8
= 24.
Hence, there are 24 purple jelly beans in the bag.
Answer:
5/6
Step-by-step explanation:
Step 1: Rewrite 9/18
9/18 = 1/2
Step 2: Rewrite problem
1/2 + 1/3
Step 3: Find GCD (Greatest common denominator)
6
Step 4: Rewrite fractions
3/6 + 2/6
Step 5: Add
5/6
I will show how to do it:
Step 1: Start your point at 3 in the y axis (line going upwards)
Step 2: Move up twice.
Step 3: Now go to the right once.
Step 4: Use a ruler to draw the line.
Step 5: Cross check by picking two points that are on the line. Or use the formula - y2 - y1 / x2 - x1
Answer:
Step-by-step explanation:
Let's re-write the equations in order to get the variables as separated in independent terms as possible \:
First equation:
Second equation:
Third equation:
Now let's subtract term by term the reduced equation 3 from the reduced equation 1 in order to eliminate the term that contains "y":
Combine this last expression term by term with the reduced equation 2, and solve for "x" :
Now we use this value for "x" back in equation 1 to solve for "y":
And finally we solve for the third unknown "z":
Answer:
V=4/3*πr^2 is the same as V=four-thirds pi &(7) cubed
