Answer: <em>936 cm²</em>
Step-by-step explanation:
<em>A = (18 × 24 × 0.5) × 2 + (18 + 30 +24) × 7 = 936 (cm²)</em>
A)
The formula for direct variation is written as Y = kx, where k is the proportion you need to solve for.
Y would be the amount raised and X would be the number of attendees:
100 = k5
Divide both sides by 5:
k = 100/5
k = 20
B. the constant of variation is the value of k above which is 20
C) Using the formula from A: y = kx, replace k with 20 and x with 60 and solve for y:
y = 20 * 60
y = 1200
They will raise $1,200
2. If the relationship is proportional the ratio would be a constant number. If the relationship is non proportional the ratio would vary between the different values.
It’s 6x6=36, because if 4 over 2 was 4 twice then 6 over 2 is 6 twice.
The distance between A and B would be 1,029 meters.
1) 0.07 zeros only matter if there is a non-zero digit, as well as the decimal to the left of it
2)90,000 it would have been 89000 if the 972 had been an 872
3).00420 must include the last zero, it is considered significant because of the reason in number one
