A box of an area covers four feet if the height of the box if 3 feet what is the volume of the box?
Answer:
12 cubic ft.
Step-by-step explanation:
A=bh=4(3)=12 ft^3
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:
4*3 =12 cubic feet
Hope this helps! :)
How do you solve equations using Substitution.
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
Solve the system by any method.
(3x – 4y = -5
(5x + 8y = -1
Answer:
( x , y ) = ( -1,1/2)
Step-by-step explanation:
Solve the equation for X
[tex]\left \{ {{x=-5/3+4/3y} \atop {5x+8y=-1}} \right.[/tex]
Substitute the given value of x into the equation 5x + 8y = -1
5(-5/3+4/3y)+8y=-1
Solve the equation for Y
y=-1/2
Substitute the given value of y into the equation x = -5 / 3 + 4 / 3y
x=-5/3+4/3×1/2
Solve the equation for X
x=-1
The system solution is the computer pair
(x,y)=(-1,1/2)
Check if the ordered pair given to the solution of the system of equations
[tex]\left \{ {{3*(-1)-4*1/2=-5} \atop {5*(-1)+8*1/2=-1}} \right.[/tex]
Simplify the equations
[tex]\left \{ {{-5=-5} \atop {-1=-1}} \right.[/tex]
The ordered pair is the solution of the system of equations, since both equations are true
(x,y)=(-1,1/2)

Step-by-step explanation:
A gardener will use up to 240 square feet for planting flowers and vegetables. She wants the area used for vegetables to be at least four times the area used for flowers. Let x denote the area (in square feet) used for flowers. Let y denote the area (in square feet) used for vegetables. Shade the region corresponding to all values of x and y that satisfy these requirements.

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:

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:
Step-by-step explanation:
4x-2 +3x+7 = 180
7x + 5 = 180
7x = 175
x = 25
3(25) + 7 = 82
Answer:
82 (degrees)
Step-by-step explanation:
4x-2+3x+7=180=7x+5...175=7x...x=175/7... x=25
This is both angles combined which we know adds up to half of the entire quadrilateral (180 degrees). Then solve.
3(25) +7=82 which is equal to f
f=82
A shoe is having a sale where everything is 35% off. you buy a pair of shoes that has a regular price of $85 what is the sale price of the shoes
Answer:
$55.25
Step-by-step explanation:
35% × 85 = 29.75
85 - 29.75
= 55.25
The profit of a football club after a takeover is modeled by p(t)=t^3-14t^2+20t+120,where t is the number of years after the take over, in which years was the club making a loss ?
When looking at the following expression, we can tell that it has no rational roots. However, it does have zeros at:
t = -0.45, 2.16, 12.29.
When thinking of the cubic curves you know that p(t) < 0 for 2.16 < t < 12.29. Meaning the team took a loss in years 3-12.

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 ^^
