Given that we have 47 kids and each kid needs 10 marbles, find out how many bags of 24 marbles will we need.
First, we will multiply 47 by 10 to get the amount of marbles needed.
47 x 10 = 470
So, that means we need 470 marbles in total.
Then, we divide 470 by 24 to see how many bags of 24 marbles 470 marbles is.
470 / 24 = 19.5833
Since, we can't have 19.5833 bags, we have to check what it would be if we only used 19.
19 x 24 = 456
470 - 456 = 14
Since, 18 is the closest number of bags but it has less than 470 it would not be correct.
Therefore, the best answer would be B. 25 since it is better to have extra marbles but not a very wide margin.
Let
x = salesperson's weekly paycheck
y = second salesperson's paycheck
We have the following system of equations:
x + y = 1025
x = 1.40y
Solving the system:
x + y = 1025
1.40y + y = 1025
2.40y = 1025
y = 1025 / 2.40 = 427.0833333 $
x = 1.40y
x = 1.40 * (427.0833333) = 597.9166666 $
answer:
the amount of each paycheck is:
first persons paycheck = 597.92 $
second persons paycheck = 427.08 $
The original price of the shirt would be $30
Y+2x=24
product is max
xy=max
we have
y+2x=24
minus 2x both sides
y=24-2x
sub that for y in xy=max
(24-2x)(x)=max
-2x^2+24x=max
we have a parabola opening down
the coordinates of the vertex is our answer
the x value of the vertex is -b/2a where
ax^2+bx+c=y
-24/2(-2)=-24/-4=6
xvalue=6
we can just sub
y=24-2x
y=24-2(6)
y=24-12
y=12
the numbers are 6 and 12
the product is 72
the numbers are 6 and 12
The formula for area of a trapezoid is:
Sides a is the top line and side b is the base, or bottom line. Add the sides together and divide by 2. After you do that, multiply the answer by the height.
Height is the length between the two sides, a and b.
