The temperature of a pot of water is 50⁰ F. The temperature rises 15⁰ per minute. Write an equation below in y=mx + b form to express this situation.
Answer:
The equation to express this situation is y = 15x + 50.
Step-by-step explanation:
Initially, the temperature of a pot of water is 50⁰, i.e. at after x = 0 minutes the temperature was, y = 50⁰.
And the temperature rises 15⁰ per minute.
So, after x₁ = 5 minutes, the temperature was, y₁ = 125⁰.
And similarly after x₂ = 10 minutes, the temperature was, y₂ = 200⁰.
Compute the equation to express this situation as follows:
[tex](y-y_{1})=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\cdot (x-x_{1})\\\\(y-125)=\frac{200-125}{10-5}\times (x-5)\\\\y-125=15x-75\\\\y=15x-50[/tex]
Thus, the equation to express this situation is y = 15x + 50.

A boat travels with velocity vector (25, 25 StartRoot 3 EndRoot). What is the directional bearing of the boat?
Answer:
The directional earing is N 30° E
Step-by-step explanation:
The given velocity vector is (25, 25·√3), therefor, we have;
R = 25·i + 25·√3·j
The angle of inclination of the direction of the boat with the horizontal = Arctan (y/x)
Where;
(x, y) = The coordinate of the components of the velocity of the boat
Therefore;
Arctan (y/x) = Arctan (25·√3/25) = Arctan (√3) = 60° North of East
The directional bearing which is the bearing relative to the northern direction is given as follows;
The directional earing = 90° - 60° = N 30° E.

What is the interest you will pay if you borrowed $900 at 10% interest for 2 years?
Answer:
$180
Step-by-step explanation:
Simple interest formula:
I = R x T x P divided by 100
=(900 x 2 x 10) / 100
=18000 / 100 = 180
=$180
A car traveling along a long straight highway at a constant speed passes a rest area. The distance d, in miles, the car must travel to reach the next rest area as a function of the time t, in hours, is modeled by d(t) = 100 - 65t . a) What does the 100 represent in the context of the problem? b) What does the 65 represent in the context of the problem?
Answer:
100 is the distance between that rest stop and the next 65 is the speed in which the car is traveling
Two sides of a triangle are 12 meters and 16 meters. What is the largest the third side can be?
A) 22 meters
B) 24 meters
C) 26 meters
D) 28 meters
Answer:
The largest third side would be 26 meters.
Option B is correct.
Step-by-step explanation:
We are given two sides of triangle 12 meters and 16 meters.
We need to find What is the largest the third side can be?
We know that the length of third side should be less than the sum of two sides of triangle
third side < length of first side + length of second side
third side < 12+16
third side < 28
So, the length of third side should be less than 28
We need to find the largest the length of third side can be: from options 22, 24 and 26. We would not consider 28 because length should be less than 28.
So, the largest third side would be 26 meters.
Option B is correct.

Find the GCF of 24, 48, and 480.
Answer:
The common factors for 24 , 48 , 480 are
1 , 2 , 3 , 4 , 6 , 8 , 12 , 24
1 , 2 , 3 , 4 , 6 , 8 , 12 , 24
1 , 2 , 3 , 4 , 6 , 8 , 12 , 24
The GCF (HCF) of the numerical factors 1,2,3,4,6,8,12,24
Step-by-step explanation:
Answer:
24
Step-by-step explanation:
Prime factorization.
24= 2*2*2*3
48= 2*2*2*2*3
480= 2*3*2*5*2*2*2
The numbers that appear the most often for all 3 numbers is: 2, 3, 4. I got 4 because of 2*2.
Multiply 2*3*4 which equals 24. The GCF of 24, 48, and 480 is 24.

Answer:
24x^3-30x^2+36x
Step-by-step explanation:
you distribute.
(2x+3)(4x^2-5x+6)
distribute the 2x first
3(4x^2*2x-5x*2x+6*2x)
then simplify
3(8x^3-10x^2+12x)
then distribute again (I'm distributing and multiplying it out in this step)
24x^3-30x^2+36x

Answer:
C. 40
Step-by-step explanation:
Start with multiplying the 120 students who took the computing and networking courses with 1160 hours. 120 times 1160 = 139200
That means that 139200 hours of the 164800 hours are by the students who took computing and networking classes, so now we have to subtract.
164800 - 139200 = 25600
Now divide 25600 with 640, because 25600 is the hours for the business course. 25600/640 = 40
So there's 40 students

Answer:
13 miles
Step-by-step explanation:
It tells us that her house is 5 miles from the Post Office. So we know that each unit on the grid is 1 mile. Lucy walks from her house to the post office to the bank. The shortest path is the hypotenuse of the right triangle. We have one side length. Now, we count the post office to bank's length. It is 12 miles. The Pythagorean theroem is a^2+b^2=c^2 so 5^2+12^2=c^2 Solving this, we get c=13. The shortest path is 13 miles.

arc RQ = 160°
Step-by-step explanation:
The length of smaller arc RQ is twice of the inscribed angle it sees
(5x + 15) × 2 = 10x + 30
9x + 17 + 6x - 12 + 10x + 30 = 360° add like terms
25x + 35 = 360
25x = 360 - 35
25x = 325 divide both sides by 25
x = 13 now the measure of arc RQ
10x + 30 ➡ 10 × 13 + 30 = 160°
