Answer:
A = 1.5x + 1400
Step-by-step explanation:
Let us represent
The number of Adults = x
The number is children = y
The total amount of money raised = A
We are told in the question that:
A pancake breakfast fundraiser served 400 people and charged $5 for adults and $3.50 for children.
Hence:
x + y = 400.... Equation 1
y = 400 - x
Hence:
A = $5 × x + $3.50 × y
A = 5x + 3.50y
Where y = 400 - x
A = 5x + 3.50(400 - x)
A = 5x + 1400 - 3.50x
A = 1.5x + 1400
The equation for how much money was raised is given as:
A = 1.5x + 1400
456.89 would be 456.9 rounded to the nearest tenth.
Answer:
<h2><em><u>80</u></em><em><u>%</u></em>.</h2>
Step-by-step explanation:
<em><u>Since</u></em><em><u>,</u></em>
Any number if divided by hundred then that no. is known as a <em><u>percentage</u></em>.
<em><u>Here</u></em><em><u>,</u></em>
<em><u>80</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>divided</u></em><em><u> </u></em><em><u>by</u></em><em><u> </u></em><em><u>100</u></em><em><u> </u></em><em><u>i</u></em><em><u>. </u></em><em><u>e</u></em><em><u>.</u></em>
80 / 100
= <em><u>80% (Ans)</u></em>
We must remember the equation to find the area of a trapezoid first.
Area =
A and B are the bases (6 and 12)
The height is 6 for each trapezoid
Now Solve!
====================================================================
SOLVING...
Area =
Area =
Area = 9 * 6
Area = 54
Since there are two trapezoids, multiply 54 by 2
54 x 2 = 108
Area = 108
