Answer:
20&22
Step-by-step explanation:
let the numbers be X and X+2.
By question, X×(X+2)=440
or, X^2+2X=440
or, X^2+2X-440=0
or, X^2+(22-20)X-440=0
or, X^2+22X-20X-440=0
or, X(X+22)-20(X+22)=0
or, (X+22)(X-20)=0
Either,X-20=0 Or, X+22=0
•°•X=20(true) •°• X=-22(false)
•°•X=20
•°•X+2=20+2=22
•°• The two consecutive even numbers are 20 and 22.

Physical therapists measure strength on a dynamometer, which uses a unit called a foot-pound. Suppose you increase the strength in your elbow joint from 90 foot-pounds to 125 foot-pounds. Find the percent of increase to the nearest percent.
A.
39%
B.
138.9%
C.
28%
Answer:
A. 39%
Step-by-step explanation:
(125-90)/(90)=(35)/(90)=0.3889 or 39%
To find the percent increase, we need to divide the amount of change by the original amount.
Compute $\sqrt{64} + \sqrt{225} - \sqrt{64 + 225}$.
Answer:
6
Step-by-step explanation:
Simplify the following:
sqrt(64) + sqrt(225) - sqrt(64 + 225)
Hint: | Evaluate 64 + 225.
64 + 225 = 289:
sqrt(64) + sqrt(225) - sqrt(289)
Hint: | Simplify radicals.
sqrt(289) = sqrt(17^2) = 17:
sqrt(64) + sqrt(225) - 17
Hint: | Simplify radicals.
sqrt(64) = sqrt(2^6) = 2^3:
2^3 + sqrt(225) - 17
Hint: | In order to evaluate 2^3 express 2^3 as 2×2^2.
2^3 = 2×2^2:
2×2^2 + sqrt(225) - 17
Hint: | Evaluate 2^2.
2^2 = 4:
2×4 + sqrt(225) - 17
Hint: | Multiply 2 and 4 together.
2×4 = 8:
8 + sqrt(225) - 17
Hint: | Simplify radicals.
sqrt(225) = sqrt(15^2) = 15:
8 + 15 - 17
Hint: | Evaluate 8 + 15 - 17.
8 + 15 - 17 = 6:

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is amperes when the resistance is ohms. What is the current when the resistance is ohms?
Answer:
[tex]\mathbf{I = 0.22 \ amperes}[/tex]
Step-by-step explanation:
From above:
let assume that;
The current is [tex]\dfrac{1}{2}[/tex] ampere when resistance is 240 ohms.
Now, to find the current when R = 540 ohms.
SO; if [tex]I \ \alpha \ \dfrac{1}{R}[/tex]
[tex]I \ =\ \dfrac{k}{R}[/tex] where k = constant
[tex]\dfrac{1}{2} \ =\ \dfrac{k}{240}[/tex]
[tex]2k = 240[/tex]
[tex]k = \dfrac{240}{2}[/tex]
[tex]k = 120[/tex]
Thus; the constant = 120
So; when R = 540 ohms
then the current will be:
[tex]I = \dfrac{k}{R}[/tex]
[tex]I = \dfrac{120}{540}[/tex]
[tex]\mathbf{I = 0.22 \ amperes}[/tex]
Personal Statement
Please include a personal statement about why you are applying and what you feel you can contribute to the program. Your statement should be a minimum of 500 words and include the following information: Why would you like to attend this Oxbridge program? Please tell us about your academic and extracurricular interests. Be sure to include your current, unweighted grade point average (GPA) or your school's equivalent. What interests you about the Major and/or Minor/Workshop courses you intend to pursue? What do you feel you will contribute to the program? Feel free to share any additional details that you feel may help our Admissions Team understand why you are a good fit for this program.
so can someone help me cause I'm not sure how to write this on a way that is convincing
Well, as it says, your first statement needs to explain what interests you about the program.
If you feel you need multiple paragraphs, let the first be an introduction, around 4 or 5 sentences. Include, possibly what pushed you to apply for this program, what you're looking forward to, and a reason for them to hire you. You can add a thesis statement of sorts if that helps (a short statement, usually one sentence, that summarizes the main point or claim of a paper). The first paragraph can be short, it doesn't need to be too in-depth. You can talk more about that later in your statement.
The body paragraphs must include your goals and extracurricular interests (what courses would you like to take and why?).
As it states, you must list your GPA, what interests you about the Major and/or Minor/Workshop courses, and what you can contribute (you can build off of what you said in your first paragraph here).
It is very important to share additional details you think are important, such as accomplishments you are proud of, for example.
A conclusion would be nice, a short and sweet wrap-up of your overall statement (not too long).
Remember, the name of the game is to sound confident and prove to them that you are in fact a good fit for the program! Good luck! Stay focused ^^

Answer:
9 is the correct answer all the best
Step-by-step explanation:
(x + 0.5)/6 = 19/12
2(x + 0.5) = 19 (multiply 12 on both sides)
x + 0.5 = 9.5 (divide 2 on both sides)
x = 9 (subtract 0.5 on both sides)
The answer is 9.

Answer:
12 ft ^3
Step-by-step explanation:
Volume of the box would be width x length x height
If the box of an area already covers four feet (width times length) we just need to multiply by the height:

A giant tortoise travels at 0.17 miles per hour and an arctic hare travels at 37 miles per hour. If
The tortoise and the hare start out together and after half an hour the hare stops to take a rest. How long does it take the tortoise to catch up
Answer:
3.145 Hours
Step-by-step explanation:
37÷2=18.5
18.5×.17=3.145
It will take the tortoise to catch up with the hare 109 hours.
Given that,
A giant tortoise travels at 0.17 miles per hour and an arctic hare travels at 37 miles per hour. If The tortoise and the hare start out together and after half an hour the hare stops to take a rest. How long it takes the tortoise to catch up is to be determined.
Speed is defined as when an object is in motion, the distance covered by that object per unit of time is called speed.
Here,
Distance traveled by hare in half hour,
= speed * time
= 37 * 1/2
= 18.5 miles
Time is taken by the tortoise to catch up with the hare,
= distance / speed
= 18.5 / 0.17
≈ 109 hours
Thus, it will take the tortoise to catch up with the hare 109 hours.

Step-by-step explanation:
A scientist measures the change in the temperature of a chemical solution. At the start of the experiment, the solution is at a temperature of -14.96ºC. The temperature decreases 2.9ºC each hour. 1️⃣ Find the temperature of the solution after 3 hours. 2️⃣ Find the temperature of the estimated solution after 3 hours.
Answer:
-6.26°C
Step-by-step explanation:
Given that:
Initial temperature = - 14.96ºC
Temperature change per hour = 2.9ºC
Hence, the temperature of the solution after 3 hours can be obtained thus :
Final temperature = (initial temperature + (temperature change per hour * Number of hours))
Temperature after 3 hours :
-14.96 + 2.9(3)
-14.96 + 8.7
= - 6.26

Two snakes race the speed of the first is 24 1/2 inches per minute and the speed of the other is 26 inches per minute how far apart with they be in 3 min? 10 min?
Answer:
637, 245
Step-by-step explanation:
Speed is the rate of change in the position of an object. The distance between the two snakes after 10 mins is 15 inches.
What is the relation between speed, distance, and Time?We know that sped, distance, and time all are in a relationship to each other. this relationship can be given as,
[tex]\rm{Speed = \dfrac{Distance}{Time}[/tex]
Given to us
Two snakes race The speed of the first is 24 1/2 inches per minute The speed of the other is 26 inches per minute What is the distance between them after 3 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 3 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 3\ mins\\= 4.5\ inches[/tex]
Thus, the distance between the two snakes after 3 mins is 4.5 inches.
What is the distance between them after 10 mins?The relative speed between them, as they are moving in the same direction, therefore,
Relative speed = (26-24.5) = 1.5 inches per minute
[tex]\text{Distance between them after 10 mins}= \rm speed \times \rm time[/tex]
[tex]= 1.5 \times 10\ mins\\= 15\ inches[/tex]
Thus, the distance between the two snakes after 10 mins is 15 inches.
