X, Y and Z form the vertices of a triangle, where ∠ YXZ = 68°, XY = 7.3m and XZ = 8.3m. Calculate the area of the triangle. Round your answer to 1 DP.
Answer: Area = 28.2m²
Step-by-step explanation: The triangle YXZ is shown in the figure below.
Area of a triangle is calculated by the formula:
[tex]A=\frac{1}{2} (base*height)[/tex]
According to the figure, the base of this triangle is b = 8.3m.
Height is a perpendicular line created from one side and intersecting the opposite angle.
To determine the height, use trigonometric relations to angle 68:
[tex]sin(68)=\frac{h}{7.3}[/tex]
h = 7.3*sin(68)
h = 7.3*0.93
h = 6.8
Now, area of triangle YXZ is
[tex]A=\frac{1}{2} (8.3*6.8)[/tex]
A = 28.2
Area of triangle YXZ is 28.2m².

Together, teammates Pedro and Ricky got 2675 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each player have?
Answer:
1199 for ricky, 1476 for Pedro
Step-by-step explanation:
2675-277=2398
2398 / 2 = 1199
each player had 1199 bases, pedro however, had 277 more bases than ricky
1199 + 277 = 1476
By solving a system of equations, we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.
How many hits did each player have?Let's define the variables:
P = base hits of Pedro last season.R = base hits of Ricky last season.Then we have that the total number of base hits last season is 2675, so we have:
P + R = 2675
We also know that Pedro has 277 more hits than Ricky, then:
P = 277 + R
To solve these equations, we can replace the second equation into the first one:
P + R = 2675
(277 + R) + R = 2675
2*R = 2675 - 277 = 2,398
R = 2,398/2 = 1,199
So we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.

In a triangle, the base is increasing at a constant rate of 2.8 cm per second, while the height is decreasing at a constant rate of 0.7 cm per second. At the instant when the base of the triangle is 6 cm and the height of the triangle is 10 cm, what is the rate of change of the area of the triangle?
Answer:
Step-by-step explanation:
Area of a triangle = 1/2bh
b is the base
h is the height
dA/dt = dA/db * db/dt + dA/dh * dh/dt
h = 10cm
b = 6cm
dA/db = h/2 = 10/2
dA/db = 5cm
dA/dh = b/2
dA/dh = 6/2 = 3cm
db/dt = 2.8cm/s
dh/dt = 0.7cm/s
Substitutte into the formula;
dA/dt = 5(2.8) + 3(0.7)
dA/dt = 14 + 2.1
dA/dt = 16.1cm²/s
Hence the rate of change of the area of the triangle is 16.1cm²/s
Brett is working at Subway to help pay for his college tuition. Johnny is getting paid $8.75 an hour. The manager of the Subway asked Johnny to work nights. If Johnny agreed, the manager would give him a bonus of $125 a week. Johnny is trying to figure out how much he would make if he worked between 30 - 35 hours a week and took the night shift. Find the reasonable domain and range. Create a relation, mapping diagram and table.
Answer:
Between $387.50 - $431.25 a week
Step-by-step explanation:
8.75x30 = 262.50
262.50+125 = 387.50
8.75x35 = 306.25
306.25+125 = 431.25

You are ordering shirts for the math club at your school. Short-sleeved shirts cost $10 each. Long-sleeved shirts cost $12 each. You have a budget of $300 for the shirts. Let x = the number of short sleeved shirts and let y = the number of long sleeve shirts.
Twelve students decide they want short-sleeved shirts. How many long-sleeved shirts can you order?
Answer:
15 long-sleeved shirts can be ordered.
Step-by-step explanation:
x = amount of short-sleeved.
y = amount of long-sleeved.
10x + 12y = 300
10(12) + 12y = 300
120 + 12y = 300
12y = 300 - 120
12y = 180
y = 180 / 12
y = 15

Use the equation to determine the cost of each ticket. Verify your solution. B) Olivia is Edan's cousin. Olivia has asked Edan to purchase tickets for her friends as well. Edan has now purchased 6 tickets in total. Use an algebraic equation to determine the total cost to Edan? C) Olivia has come down with the flu, and her friends no longer want to attend the concert. Edan is thinking of selling the 6 tickets she bought. Her goal is to earn $100 after selling the tickets. Using the equations from part a) and b), how much should Edan sell each ticket for, if she wants to make a profit of at least $100?
Answer:
a) $21
b) $133.75
c) $233.75
Step-by-step explanation:
Edan buys 3 tickets to a concert. When the delivery charge of $7.75 per order is added to the cost of the tickets, the total cost is $70.75.
A) Create an algebraic equation for this problem. Use the equation to determine the cost of each ticket. Verify your solution.
Let the number of tickets be represented by x
The equation is:
3x + 7.75 = 70.75
3x = 70.75 - 7.75
3x = 63
x = 63/3
x = $21
Each ticket cost $21
B) Olivia is Edan's cousin. Olivia has asked Edan to purchase tickets for her friends as well. Edan has now purchased 6 tickets in total. Use an algebraic equation to determine the total cost to Edan?
1 ticket cost = $21
Let the number of tickets be represented by x
Hence, the equation is
21x + $7.75
21 × 6 + $7.75
= 126 + $7.75
= $133.75
C) Olivia has come down with the flu, and her friends no longer want to attend the concert. Edan is thinking of selling the 6 tickets she bought. Her goal is to earn $100 after selling the tickets. Using the equations from part a) and b), how much should Edan sell each ticket for, if she
Profit = Selling price - Cost Price
Cost price = $133.75
Profit = $100
Selling price = Cost price + Profit
Selling price = $133.75 + $100
= $233.75
