Jaden is flying a kite with an angle of elevation of 33 degrees. If Jaden lets out 275 feet of string, how high above the ground is the kite flying? Round answers to the nearest tenth place.
Answers
Answer:
149.8 feet
Step-by-step explanation:
θ = Angle of elevation = 33°
The length of string Jaden lets out = Hypotenuse = 275 feet.
How high above the ground that the kite is flying = Opposite Side.
We are solving this question using the Trigonometric function of Sine
Sin θ = Opposite Side/Hypotenuse
Sin 33 = Opposite/275 feet
Cross Multiply
Sin 33 × 275 feet = Opposite
Opposite side(Height ) = 149.77573463 feet
Approximately to the nearest tenth = 149.8 feet

Answer:
a=169 ft
Step-by-step explanation:
Here you are given the angle 25, and the opposite and hypotenuse values.
Opposite/Hypotenuse: the sin(angle 25)=a/400ft.
We need to solve for a, so lets multiply 400 to the other side:
400(sin25)=a. Plug this into your calculator and you will get the answer: a=169.04 ft

A local restaurant served 124 cups of pancake mix every hour it takes 1 1/4 cups of mix to make one pancake the pancakes are all equal in size about how many pancakes can the restaurant make in two hours
Answers
Answer: The restaurant can make 199 pancakes in two hours.
Step-by-step explanation:
Given: Total number of cups of pancake mix used in 1 hour = 124
Mix required for each pancake = [tex]1\dfrac14=\dfrac{5}{4}[/tex]
Number of cups of pancake mix used in 2 hours = 2 x 124 = 248
Number of pancakes made = (Number of cups of pancake mix used in 2 hours ) ÷ (Mix required for each pancake )
[tex]=248\div\dfrac54\\\\=248\times\dfrac45\\\\= 198.4\approx199[/tex]
Hence, the restaurant can make 199 pancakes in two hours.

Adele took a total of 12 quizzes over the course of 2 weeks. After attending 5 weeks of school this quarter, how many quizzes will Adele have taken in total? Assume the relationship is directly proportional.
?quizzes
Answers
Answer:
30 quizzes
Step-by-step explanation:
12 quizzes in 2 weeks means that there were 6 per week and 6 (quizzes per week) times 5 (number of weeks) would be 30.
Hope this helped!!
Answer:
30, or 42
Step-by-step explanation:
If they took 12 quizzes over the course of 2 weeks, then we can assume that they take 6 quizzes each week (12/2 = 6).
Over the course of 5 weeks, they'll have taken 30 quizzes if the above is true. However, the 'or' is there because I don't know if they're including the past 12 or not. If they are including the 12 quizzes taken over 2 weeks, then the answer is 42. If they are only referring to the 5 weeks of school, then the answer is 30.

−1.94. The regression line overpredicts the temperature change.
−3.02. The regression line underpredicts the temperature change.
Answers
Given:
The regression equation for change in temperature, y, to amount of rain, r, is given by
[tex]\hat{y}=0.2-1.4r[/tex]
The observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.
To find:
The residual and interpret it.
Solution:
According to the question, the observed amount of rain was 0.4 inches and the temperature change was 2.3 degrees.
So, the actual value is 2.3 degrees.
Put r=0.4 in the given equation, to find the predicted value.
[tex]\hat{y}=0.2-1.4(0.4)[/tex]
[tex]\hat{y}=0.2-0.56[/tex]
[tex]\hat{y}=-0.36[/tex]
We know that,
Residual = Actual value - Predicted value
[tex]Residual=2.3-(-0.36)[/tex]
[tex]Residual=2.3+0.36[/tex]
[tex]Residual=2.66[/tex]
Residual is positive because predicated value is less than the actual value.
So, the regression line underpredicts the temperature change.
Therefore, the correct option is B.
Jessa started with 100 sugar cookies for the Christmas banquet and gave away x cookies. Cooper started with 120 cookies but gave away twice as many pieces as Jessa did. How many sugar cookies did Jessa give away if they had the same number left?
Answers
Answer:
20 cookies
Step-by-step explanation:
To find the answer start by plugging in numbers. first, subtract the number from 100 or Jessa's number of cookies then multiply that by 2 and subtract that from 120 or Cooper's cookies. If the two resulting numbers are equal then you have the right answer.
A gannet flies 24 1/2ft above sea level. It increases its elevation by 5ft. Then it dives and changes its elevation by -47 2/3ft. After it dives, what is the gannets elevation relative to sea level?
Answers
Answer:
Its elevation relative to the sea level is -18 1/6 ft (it is 18 1/6 below sea level)
Step-by-step explanation:
Here, we want to calculate the elevation relative to sea level
The sea level refer to the base of the sea
We follow the flight procedure;
distance of 24 1/2 ft above sea level , then go further up by 5
its elevation now is 24 1/2 + 5 = 29 1/2 ft
A change of -47 2/3 ft
So the elevation now will be;
29 1/2 - 47 2/3
= 59/2 - 143/3
= (177-286)/6 = -109/6
= -18 1/6 ft

The graph for the equation Y= 2X+4 is shown below.
If another equation is graphed so that the system has one solution, which equation could that be?
Oy= 2x-4
Oy=2(x+ 2)
Oy=2(x-4)
Oy=x+4
Answers
To have only one solution the two lines must have different slopes, then the correct option is:
y = x + 4.
Which equation could it be?
We want our system to have exactly one solution, so the two lines must have different slopes.
The already graphed line s:
y = 2x + 4
Notice that the slope is 2, then we need to select the option with an slope different than 2, which is the last option:
y = x + 4
If we graph that line, the system will have only one solution.
