Answer:
BC = 4.7
Step-by-step explanation:
From the question given above, the following data were:
Angle A = 21 °
Hypothenus = AC = 13
Opposite = BC =?
The length of BC can be obtained by using sine ratio as illustrated below:
Sine A = Opposite /Hypothenus
Sine 21 = BC / 13
0.3584 = BC / 13
Cross multiply
BC = 0.3584 × 13
BC = 4.7
Thus, the length of BC is 4.7

Molly bought c candy canes. She paid $1.05, including tax, per candy cane. She gave the cashier $10 and received $1.60 in change. How many candy canes did Molly purchase? Please hurry
Answers
Answer:
Number of candy = 8 candy canes.
Step-by-step explanation:
Cost per candy = $1.05
Amount paid = $10
Change received = $1.60
Total cost = amount paid - change received
Substituting into the equation, we have;
Total cost = 10 - 1.6
Total cost = 8.4
To find the number of candy purchased;
Number of candy = total cost/cost per candy
Number of candy = 8.4/1.05
Number of candy = 8 candy canes.
Therefore, Molly purchased 8 candy canes.

The equation of the proportional relationship represented by the table and the graph is: y = 2x.
What is a Proportional Relationship?If m is the slope or unit rate, a proportional relationship between two variables, x and y, can be represented with an equation as, y = mx.
Let's find the equation that represents the relationship represented by the graph and the table. Let's use the graph.
m = y/x
Using the point, (2, 4),
m = 4/2 = 2
Substitute m = 2 into y = mx
y = 2x
Therefore, the equation of the proportional relationship represented by the table and the graph is: y = 2x.

1. x≤5 Work: 2x+9≤19 move the constant to the right then its 2x≤19-9, then subtract the numbers and it would be 2x≤10, then divide both sides of the inequality by 2 which gives you the final answer of x≤5
2. x≥19 Work: x-7≥12 move the constant to the right then its x≥12+7, then add the numbers and get your final answer of x≥19
3. x≤4 Work: Divide both sides of the inequality by -3 and flip the inequality sign and that gives you -3÷(-3)≤-12÷(-3) and divide that which gives you x≤4
4. x<-3 Work: move the constant to the right which gives you -5x>16-1, then subtract to get -5x>15 and divide both sides of the inequality by -5 and flip the inequality sign to get x<-3
Note: This Took Forever LOL

A volleyball camp chargers $150 per camper for 10 campers. When a team brings 15 campers, the rate is reduced to $125 per camper. What is the rate of change in cost per camper ?
Answers
Answer: $6.67
Step-by-step explanation:
A volleyball camp chargers $150 per camper for 10 campers. The cost for each camper will be:
= $150/10
= $15
When a team brings 15 campers, the rate is reduced to $125 per camper. The cost for each camper will be:
= $125/15
= $8.33
The rate of change in cost per camper will be:
= $15 - $8.33
= $6.67
