Answer:
Dividing an angle into two equal halves
Step-by-step explanation:
David starts by drawing angle CAB as shown in .
He then draws an arc cutting the sides AC at point D and AB at point E.
With center at E, an arc is drawn, followed by another arc with center at D.
The two arcs intersect at a certain point.
Connecting point A to this intersection yields the angle bisector of .
Hence, by observing the markings, he is effectively bisecting the angle.
An angle bisector is a line or segment that splits an angle into two equal angles.
Answer:
Step-by-step explanation:
Let the number of cans collected by Shane be x.
Thus, the number of cans collected by Abha is x + 178.
Given that a minimum of 2000 cans is required to be collected.
Therefore, we have the inequality,[ [TAG_19]]
Total cans by Shane + Total cans by Abha ≥ 2000.
That is,
Thus, the necessary inequality is .
Answer:
The price amounts to $9.70 per kilogram.
Step-by-step explanation:
This can be resolved using the rule of three.
In a rule of three scenario, the first step involves determining how the values are related, whether directly or inversely.
A direct relationship implies that when one measure increases, the corresponding measure also increases. In this case, cross multiplication serves as the method for the rule of three.
Alternatively, an inverse relationship indicates that an increase in one measurement causes a decrease in the other. In this scenario, line multiplication applies.
Here, the relationship is between the weight of the cheese and its cost. As the weight rises, so does the expense, representing a direct proportion.
Solution:
According to the problem, cheese is priced at $4.40 per pound. Given that each kg equals 2.2 pounds, we can deduce how many kg correspond to one pound.
1 pound - x kg
2.2 pounds - 1 kg
kg
Given that cheese costs $4.40 for a pound, and there are 0.45 kg in one pound, we calculate the cost for 1 kg.
$4.40 - 0.45 kg
$x - 1 kg
The price is $9.70 per kilogram.
