A commercial airplane travels 5,000 feet east and then ascends 3,000 feet from its starting point in the sky. Upon noticing a severe storm system on the horizon, the pilot decides to return to the starting point. A) how much distance does the plane have to travel to turn back? B) at what angle would the plane need to travel to return to its starting point. (1,000 feet = 1 unit)
Answer:
A) 5830.95 B)59.04
Step-by-step explanation:
Solve for the hypotenuse of 5,000 and 3,000
Use tangent to find the angle
tanx = 5,000/3,000
x=59.04
The distance the plane has to travel to turn back is 5830.95 km.
The angle would the plane need to travel to return to its starting point is 59.04°
How to find the distance?Solve for the hypotenuse of 5,000 and 3,000
Use tangent to find the angle
tanx = 5,000/3,000
x = 59.04

Answer:
A and B
Step-by-step explanation:
The lines are both in slope intercept form:
y=Mx+b
Where m is the slope and b is the y intercept.
We have 2 lines:
y=1/3x+3
y=1/3x-2
1/3 is the coefficient of x, which means the slope is 1/3. Both of these lines have the same slope of 1/3. Since they both have the same slope, they are also parallel lines.
Therefore, A: the same slopes and B: parallel lines is correct.
In the photo, the red line is 1/3x+3 and the blue like is 1/3x-2

Suppose you had 28 baskets of 6 apples and 5 baskets of 9 apples.
How could you quickly figure out how many baskets of 3 apples you could create?
Answer:
71 baskets of 3 apples.
Step-by-step explanation:
From each of the 28 baskets of 6 you can get 6/3 = 2 baskets of 3.
From each of the 5 baskets you can get 9/3 = 3 baskets of 3.
Therefore:-
From the 28 baskets you can create 28 * 2 = 56 baskets of 3.
From the 5 baskets of 9 you can get 5 * 3 = 15 baskets of 3.
Total 15 + 56 = 71.

On the spinner, the probability of landing on black is 1/2 , and the probability of landing on red is 1/3. Create a probability distribution for the experiment of spinning the spinner.
Answer:
1) [tex] p_i \geq 0 , \forall i[/tex]
2)[tex] \sum_{i=1}^n P_i = 1, i =1,2,...,n[/tex]
And for this case we have:
[tex] \frac{1}{2}+\frac{1}{6}= \frac{2}{3}[/tex]
By the complement rule we can find the probability that the spinner land in a non black or red space:
[tex]p(N) = 1- \frac{1}{2} -\frac{1}{3}= \frac{1}{6}[/tex]
And then the probability distribution would be:
Color Red Black N
Prob. 1/3 1/2 1/6
Step-by-step explanation:
For this case we have two possible outcomes for the spinner experiment:
[tex] p(black) =\frac{1}{2}[/tex]
[tex] p(red) = \frac{1}{3}[/tex]
In order to have a probability distribution we need to satisfy two conditions:
1) [tex] p_i \geq 0 , \forall i[/tex]
2)[tex] \sum_{i=1}^n P_i = 1, i =1,2,...,n[/tex]
And for this case we have:
[tex] \frac{1}{2}+\frac{1}{6}= \frac{2}{3}[/tex]
By the complement rule we can find the probability that the spinner land in a non black or red space:
[tex]p(N) = 1- \frac{1}{2} -\frac{1}{3}= \frac{1}{6}[/tex]

)) A triangle has sides with lengths of 5 inches, 12 inches, and 13 inches. Is it a right
triangle?
yes
no
Answer:Yes
Step-by-step explanation:
Given
Triangle has sides
length [tex]a=5\ in.[/tex]
[tex]b=12\ in.[/tex]
[tex]c=13\ in.[/tex]
If the triangle is Right angled then it must satisfy the Pythagoras rule
[tex](\text{Perpendicular})^2+(\text{base})^2=(\text{Hypotenuse})^2[/tex]
[tex](a)^2+(b)^2=(c)^2[/tex]
[tex]5^2+12^2=13^2[/tex]
[tex]25+144=13^2[/tex]
[tex]169=13^2[/tex]
[tex]13^2=13^2[/tex]
Therefore The given triangle is right angled
A triangle has sides with lengths of 8 centimeters, 14 centimeters, and 16 centimeters. Is it a right triangle?
Answer:
No, the triangle is not a right triangle
Step-by-step explanation:
In this question, we are asked to determine if the triangle having the lengths given in the question is a right triangle.
To answer this question, we need to take into consideration a very important property of right angle triangles.
The property is that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the two other sides
The hypotenuse is the one with the longest length. Thus, the hypotenuse here is 16 centimeters.
Now let’s have the squares!
The square of the hypotenuse is 16 * 16 = 256
Let’s sum the squares of the other two sides;
(8 * 8) + ( 14 * 14) = 64 + 196 = 260
These squares are not equal so we can conclude that the triangle is not a right triangle

The first company charges 6500 to rent trucks plus an additional fee of 125.50 for each ton of sugar. The second company charges 5597 to rent trucks plus an additional fee of 200.75 for each ton of sugar. For what amount of sugar do the two companies charge the same? What is the cost when the two companies charge the same?
Answer:
a. 12
b. 8006
Step-by-step explanation:
We have company A, which is determined with the following equation:
A = 6500 + 125.5 * x
where x is the amount of ton of sugar
Same for company B:
B = 5597 + 200.7 * x
We want to know when A = B are equal, therefore:
6500 + 125.5 * x = 5597 + 200.7 * x
200.75 * x - 125.5 * x = 6500 - 5597
75.25 * x = 903
x = 903 / 75.25
x = 12
That is to say that when they are 12 tons of sugar they charge the same.
To know how much the value would be:
A = 6500 + 125.5 * 12 = 8006
B = 5597 + 200.75 * 12 = 8006
That is to say that the value when it is equal is 8006
Caleb’s puppy weighs 2,250 grams. If the puppy weighed 600 grams at his last visit to the veterinarian’s office, what is the percent increase in the puppy’s weight rounded to the nearest whole number? Enter your answer in the box.
Answer:
[tex]73\%[/tex]
Step-by-step explanation:
Given: Present weight of Caleb’s puppy = 2,250 grams
Puppy weighed 600 grams at his last visit to the veterinarian’s office.
To find: percent increase in the puppy’s weight rounded to the nearest whole number
Solution:
Increase in puppy's weight = 2250 - 600 = 1650 grams
Percent increase in the puppy’s weight =( Increase in puppy's weight/Present weight of Caleb’s puppy) × 100 = [tex]\frac{1650}{2250}(100)=73.33 \%[/tex]
[tex]73.33\%[/tex] is rounded to [tex]73\%[/tex]

[tex]\sqrt{x-6}=8[/tex]
Take square,

3. What is the solution of the system of equations 3x +2y =10 and – 6x – y=-14?
Answer:
x=2 y=2
Step-by-step explanation:
Rewrite equations:
−6x−y=−14;3x+2y=10
Step: Solve−6x−y=−14for y:
−6x−y=−14
−6x−y+6x=−14+6x(Add 6x to both sides)
−y=6x−14
−y
−1
=
6x−14
−1
(Divide both sides by -1)
y=−6x+14
Step: Substitute−6x+14foryin3x+2y=10:
3x+2y=10
3x+2(−6x+14)=10
−9x+28=10(Simplify both sides of the equation)
−9x+28+−28=10+−28(Add -28 to both sides)
−9x=−18
−9x
−9
=

−9

Combine like terms, 3 and 5, on the right side of the equation.
Distribute 2 to x on the left side of the equation and 3 to x on the right of the equation.
Distribute 2 to (x + 6) and 3 to (X - 4)
Apply the subtraction property of equality to move the 6 from the left side of the equation to the right side.
Answer:
Distribute 2 to (x+6) and 3 to (x-4)

The first thing you need to do when solving an equation with parenthesis is to always simplify the expression first before solving. This makes it easier to solve the equation.
The result for the survey of 120 students who were selected randomly is listed below. The total population of students was 380. 66 students ride the yellow bus 24 students ride the city bus 30 students do not ride a bus . Based on the data, what is the best approximate for the total number Of students who ride the city bus?
Answer: 76 students
Step-by-step explanation:
Number of students surveyed = 120
Students who 66 ride yellow bus= 66
Students ride city bus = 24
Students who do not ride a bus = 30.
The fraction of students who ride the city bus will be:
= 24/120
= 1/5
Since the total population of the students is 380, the qpproximate for the total number of students that ride the city bus will be:
= 1/5 × 380
= 76 students
