Answer:
We know that the equation for the speed is:
Speed = Distance/time.
First, we know that he walks 2 miles in 15 minutes.
distance = 2miles
time = 15 minutes
Then his speed in that interval is:
Speed = (2 mi)/(15 min) = (2/15) miles per minute.
Now, at this same speed, he wants to walk 3 more miles. And we want to find the equation that represents how much time she needs to walk 5 miles (the 2 first miles plus the other 3 miles)
We use again the equation:
Speed = Distance/Time
But we isolate Time, to get:
Time = Distance/Speed
Where:
Distance = 5 miles
Speed = (2/15) miles per min
Time = (5 miles)/((2/15) miles per min) = 37.5 minutes
She needs 37.5 minutes to walk the 5 miles.

The kinetic energy, K, of an object varies jointly with its mass, m, and the square of its velocity, v. The mass of an object stays the same, but the velocity of the object is halved. How is the kinetic energy of the object affected? The kinetic energy is quartered. The kinetic energy is halved. The kinetic energy is doubled. The kinetic energy is quadrupled.
Answer:
the answer is A
Step-by-step explanation:
I took the test
The kinetic energy of the object is affected in that; The kinetic energy is quartered.
How to Solve Kinetic Energy Problems?We are told that kinetic energy, K, of an object varies jointly with its mass, m, and the square of its velocity, v. Thus;
K = mv²
Now, mass is same but velocity halved. Thus, we now have;
K = m(v/2)²
K = ¹/₄mv²
Thus, the kinetic energy is quartered.

Newton's second law in physics states that F=ma, where F is the force of an object (measured in Newtons), m is the mass of the object (in kilograms) and a is the acceleration of that object (measured in m/s). Calculate the force created from an object with a mass of 640 grams and an acceleration of 10 m/s2
Answer:
mass=640/1000kg
=0.64kg
acceleration =10m/s^2
now,
force=mass*acceleration
=0.64*10
=6.4newton

PLEASE do this fast. I will mark the correct answer brainliest. Also, please only answer with the right answer not stuff unrelated or not answering the question. Please hurry. Thank you so so so much.
Answer:
[tex]y=-\frac{1}{2} x+4[/tex]
Step-by-step explanation:
The equation of a straight line in slope intercept form is given by:
y = mx + c;
where y, x are variables, m is the slope of the line and c is the y intercept (that is value of y when x is 0).
The equation of a line passing through point ([tex]x_1,y_1[/tex]) with a slope of -1/2 is given by:
[tex]y-y_1=m(x-x_1)[/tex]
Given that the line passes through the point (-10,9) and has a slope of -1/2. Hence the equation of the line is:
[tex]y-9=-\frac{1}{2}(x-(-10)) \\\\y-9=-\frac{1}{2} (x+10)\\\\y=-\frac{1}{2} x-5+9\\\\y=-\frac{1}{2} x+4[/tex]

Answer: B. 1
Step-by-step explanation: A common factor is something that two or more numbers have in common. It is 1 because you multiply 1 by 1 to get 1, and 1 by 2 to get 2.
(1 by 1) = 1
(2 by 1) = 2
These two numbers have the number 1 in common because both 1 and 2 can only be multiplied by 1 and itself to get the number. (That is also what you call prime numbers.)

Step-by-step explanation:
Dawn is having a party. She wants to make punch and the recipe calls for 4 pints of orange juice, 5 cups of apple juice, 1/2 gallon of lemonade, and 2 quarts of pineapple juice. When she mixes this altogether, how many gallons of punch did Dawn make?
Answer:
1 13/16 gallons
1.8125 gallons
Step-by-step explanation:
convert the measures that are not in gallons to gallon
1 pint = 1/8 gallon
4 x 1/8 = 1/2
1 cup =1/16 gallon
5 x 1/16 = 5/16
0.3125
1 quart = 1/4
1/4 x 2 = 1/2
Add these figures togehter
1/2 + 5/16 + 1/2 + 1/2 = 29 / 16 = 1 13/16 gallons

Find missing measure (No.5)
Answer:
Step-by-step explanation:
61+90+76+angle 2=360(sum of four angles is always 360 degree)
227+angle 2=360
angle 2=360-227
angle 2=133
angle 1=76 degree(being vertically opposite angle)
angle 1+angle 3+120+88=360(sum of four angles ia always 360 degree)
76+angle 3+208=360
angle 3=360-284
angle 3=76 degree

Question : find the measure of angles x and y
show your work and write a sentence staring the answer
Answer:
x = 53°, y = 42°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180° for x
x = 180° - (37 + 90)° = 180° - 127° = 53°
48° + y = 90° ( subtract 48° from both sides )
y = 42°

If the company wants to keep its profits at or above $75,000, then which constraint is reasonable for the model?
−4.57 ≤ x ≤ 39.87
1.12 ≤ x ≤ 34.18
−4.57 ≤ x ≤ 1.12 and 34.18 ≤ x ≤ 39.87
0 ≤ x < 1.12 and 34.18 < x ≤ 39.87
Answer:
1.12 ≤ x ≤ 34.18
Step-by-step explanation:
____________
Answer:
The other person is correct. This will keep the companies profit above 75,000, because 1.12 < x < 34.18 goes past 75,000, and does not allow the profit to become less than.

Adult tickets to a football game costs $6 and student tickets cost $2. A total of $1776 was collected on tickets 372. How many adult tickets were sold?
Answer:
s = the number of student tickets sold a = the number of adult tickets sold The drama class sold 25 more student tickets than adult tickets to the fall play s = a + 25 The class collected $660 from ticket sales: 6s + 3a = 660 divide both sides by 3 2s + a = 220 by solving the system of equations s = a + 25 2s + a = 220 we find s = 81.67 student tickets a = 56.67 adult tickets
