Answer:
[tex]sin 40 = \frac{x}{11}[/tex]
Step-by-step explanation:
[tex]sine = \frac{opposite}{hypotenuse}[/tex]
Side x is the opposite, since it is opposite the angle you are solving for.
Side y is the adjacent, since it is next to the angle you are solving for.
The side measuring 11 is the hypotenuse, since it is across from the right angle.

A national park has two types of bears: Grizzly bears and black bears. A sciantist has reported 9 out of 12 bears she tagged are black bears. Show a model that compares the number of black bears tagged to the number of grizzly bear?
Answers
Answer:
Z = 0.75x + 0.25y
Step-by-step explanation:
Two bear types are identified :
Black bears and Grizzly bears
9 out of 12 = black bears ; Hence, 3 are grizzled
For the model:
For a bear population of Number x
Total bear population = black bear, x + grizzled bear, y
Proportion of black bear = 9/ 12 = 0.75
Grizzled bear = 1 - 0.75 = 0.25
Total bear population , Z= 0.75x + 0.25y
Hence,
Z = 0.75x + 0.25y

15 cm
Answers
Answer:
≈ 189.3 cm²
Step-by-step explanation:
The shape is composed of a rectangle and a semicircle, then
area of rectangle = 15 × 10 = 150 cm²
The semicircle has a diameter of 10 cm , so radius = 10 ÷ 2 = 5 cm
area of semicircle = [tex]\frac{1}{2}[/tex] πr² = 0.5 × π × 5² = 12.5π cm²
area of shape = 150 + 12.5π ≈ 189.3 cm² ( to 1 dec. place )

write an equation of the given line that passes through the given point and has the given slope m
(5,1);m=2
Answers
Answer:
y = 2x - 9
Step-by-step explanation:
Use slope intercept form, y = mx + b
Plug in the slope, x, and y, then solve for b:
y = mx + b
1 = 2(5) + b
1 = 10 + b
-9 = b
Then, plug in b and the slope into y = mx + b
y = mx + b
y = 2x - 9
So, the equation of the line is y = 2x - 9
Answer:
Step-by-step explanation:
y=mx+b, m=2
y=2x+b, using point (5,1)
1=2(5)+b
b=-9
y=2x-9

Devin bought a new car
for $19,024 and it was
20% off. Determine the
original price of the car.
Answers
Answer:
$23780
Step-by-step explanation:
Given data
Let the original price be x
discount= 20%
price= $19,024
so that
20/100*x=x-19,024
0.2x= x-19,024
19,024=x-0.2x
19,024=0.8x
x= 19,024/0.8
x=23780
Hence the original price is $23780

Together, teammates Pedro and Ricky got 2680 base hits last season. Pedro had 276 more hits than Ricky. How many hits did each player have?
Answers
Answer:
Ricky it is 1,202
And for Pedro = 1,202 + 276 = 1,478
Step-by-step explanation:
The computation is shown below:
Let us assume the ricky be x
So pedro be x + 276
Now the equation is
x + x + 276 = 2680
2x + 276 = 2680
2x = 2680 - 276
2x = 2404
x = 1,202
For Ricky it is 1,202
And for Pedro = 1,202 + 276 = 1,478

My sister is 18 years old. My brother says that his age minus eighteen is equal to my sister's age. How old
is my brother?
Enter an equation, using b as your variable, to find how old my brother is.
The equation is
My brother is
years old.
Answers
Answer:
The brother is 36 years old.
Step-by-step explanation:
b = brothers age
b - 18 = 18 | Given
b = 36 | Add 18 to both sides to cancel out -18 and get his age.
Answer:
36 years old or b-18 = 18
Step-by-step explanation:
Since there is an 18 year difference between the brother and the sister, all you have to do is subtract 18 from how hold the brother is. Since we know that the age of the sister is 18, the equation needs to be equal to 18. Using this, we know the equation is b - 18 = 18. When we add 18 to both sides we get that b=36.

Profit is the difference between revenue and cost. The revenue, in dollars, of a company that manufactures televisions can be modeled by the polynomial 3x2 + 180x. The cost, in dollars, of producing the televisions can be modeled by 3x2 – 160x + 300. The variable x is the number of televisions sold.
If 150 televisions are sold, what is the profit?
$2,700
$6,000
$50,700
$51,300
Answers
Answer: $50,700 is the profit
If 150 televisions are sold, the profit is $50,700.
What is profit?
Profit is the total revenue less the total cost.
Profit = total revenue - total cost
What is profit?Profit = (3x^2 + 180x) - (3x2 – 160x + 300)
Profit = (3 x 150^2 + 180 x 150) - (3 x 150^2 - 160x 150 + 300)
27,000 + 24,000 - 300
Profit = $50,700

A student is 1.75m tall and is trying out for the football team. He kicks the football straight up
in the air from his outstretched arms at a height of 1 m. If the ball hits him on the head on the
way back down 3 seconds later, what was the football's initial velocity?
Answers
Answer: see below
Step-by-step explanation: Initial velocity = terminal velocity. At the top of travel, the velocity is 0 as the ball is motionless. Then it travels 3 seconds (due to gravity). Grav is 9.8m/sec squared. So 1st second = 9.8m. 2nd second is 2x9.8m. 3rd second is 3x9.8m = 29.4 m/sec.
