A tree casts a shadow that is 125 feet in length. The angle of elevation with the sun is 32°. What is the height of the tree?
Answer:
Height of the tree is 78.11 feet.
Step-by-step explanation:
By applying the tangent rule in the right triangle formed,
Since, tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(32)° = [tex]\frac{h}{125}[/tex]
h = 125(tan32°)
h = 125(0.62487)
h = 78.109
≈ 78.11 ft
Height of the tree will be 78.11 feet.

A container holds four gallons of lemonade a large lemonade contains 16 oz how many large Lemonade's Cuisine Restaurant sell before they run out of lemonade
Answer:
32 Large lemonade
Step-by-step explanation:
A container holds four gallons of lemonade a large lemonade contains 16 oz how many large Lemonade's Cuisine Restaurant sell before they run out of lemonade
1 gallon = 128 oz
Hence, 4 gallons = x
x = 4 × 128 0z
x = 512 oz of Lemonade
If
1 large lemonade = 16 oz
16 oz = 1 large lemonade
512 oz = x
x = 512/16
x = 32 large lemonades
The restaurant will.sell 32 large lemonade

Statistics and probability: If the glucose level is above 160mg per dl one hour after a sugary drink, Sheila's measured glucose level one hour after the sugary drink varies according to the normal distribution with the mean being 145mg/dl and a standard deviation of 11mg/dl. If a single glucose measurement is made, what is the probability that Sheila is diagnosed with gestational diabetes?
Answer:
0.0863
Step-by-step explanation:
Given that:
The mean =145
The standard deviation = 11
To find P(X ≥ 160) :
Z = (x - μ)/σ
Z = 160 - 145/ 11
Z = 1.364
From the standard normal z table
Thus;
P(X ≥ 160) = 1- P(Z < 1.364)
P(X ≥ 160) = 1 - 0.9137
P(X ≥ 160) = 0.0863
Sam has some pennies, dimes and nickels in his pocket which total 52 cents. He has two more nickels than dimes and three times as many pennies as nickels. How many of each coin does he have?
Answer:
Step-by-step explanation:
Let the amount of pennies be x
amount of dimes be y
amount of nickels be z
If it all totaled 52, then x+y+z = 52
If he has two more nickels than dime, then;
z = y + 2
y = z-2
If he has three times as many pennies as nickels;
3x = z
x = z/3
Subtitute the funcion in original function;
z/3 + (z-2) + z = 52
z + 3z - 6 + 3z = 156
7z - 6 = 156
7z = 162

△ABC is reflected over the x−axis and then reflected over the y−axis to form ΔA''B''C'' as shown below.
Answer:
D
Step-by-step explanation:
Because it is.
The general rule maps △ABC onto ΔA''B''C'' is (x,y) turns to (x, -y). so option C is correct.
How does reflection across axis work?When a graph is reflected along an axis, say x axis, then that leads the graph to go just in opposite side of the axis as if we're seeing it in a mirror.
If we study it more, you will find that its symmetric, thus each point is equidistant from the axis of reflection as that of the image of that point.
Thus, if we are reflecting a point (x,y) along x axis, then its abscissa will stay same but ordinates will negate. Thus (x,y) turns to (x, -y)
Similarly, if we are reflecting a point (x,y) along y axis, the resultant image of the point will be (-x,y)
△ABC is reflected over the x−axis and then reflected over the y−axis to form ΔA''B''C'' is shown.
The general rule maps △ABC onto ΔA''B''C'' is (x,y) turns to (x, -y). so option C is correct.

(PLEASE SOLVE ASAP!!) Suppose the entry fee to Arches national park is $25 per vehicle. Suppose the entrance fee to Bryce national park can be represented by the equation y=30x, where y represents the total cost in dollars, and x represents the number of vehicles. Which park has the greatest cost per vehicle?
Answer:
Bryce national park has the greatest cost per vehicle.
Step-by-step explanation:
From the question, we are given the following:
For Arches national park
Cost per vehicle or entry fee per vehicle at Arches national park = $25
For Bryce national park
We have:
y = 30x ........................... (1)
y = the total cost in dollars
x = the number of vehicles
To obtain the cost per vehicle at Bryce national park, we have to assume that the number of vehicles is one by setting x equal to one, that is, x = 1.
Substituting x = 1 into equation (1), we have:
y = 30 * 1 = 30
This implies that cost per vehicle at Bryce national park is $30.
Conclusion
Since the $30 cost per vehicle at Bryce national park is greater than the $25 cost per vehicle at Arches national park, it therefore implies that Bryce national park has the greatest cost per vehicle.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour.
Option D is the correct answer.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 8 is an equation.
We have,
y = -2x + 43
Where y is the temperature after x hours.
Now,
At x = 0,
y = 43
This means the temperature is 43 when it first started to measure.
At x = 1,
y = 41
This means,
The temperature decreases by 2 degrees per hour
Thus,
It was 43'F when the temperature was first measured, and it is dropping by 2 degrees per hour.
Option D is the correct answer.
