The area of the surface of an office desk is 10 square feet. The perimeter is 14 feet. What are the dimensions of the desk?
Answers
Answer:
5ft and 2ft
Step-by-step explanation:
Area = bh or lw
Perimeter = 2(l) + 2(w)
Find factors of 10: 1, 2, 5, 10
1 and 10 is not right because Perimeter would be too big and not equal 14)

1/3a = −5
What does a equal?
Answers
1. Combine multiplied terms into a single fraction
1/3 = −5
1a/3 = -5
2. Multiply by 1
1a/3 = -5
a/3 = -5
3. Multiply all terms by the same value to eliminate fraction denominators
a/3 = -5
3 • a/3 = 3 (-5)
4. Cancel multiplied terms that are in the denominator
3 • a/3 = 3 (-5)
a = 3 (-5)
5. Multiply the numbers
a = 3(-5)
a = -5

Jane incorrectly finds the volume of the cone using the following work. Explain Jan’s error and find the correct volume AND surface area. Show all work
Answers
Answer:
V=39.25. the height is not 6.25, 6.25 is the slope. you have to use Pythagoras theorem to find the height, then you can find the volume.
The surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².
What is of volume of cone?
Volume of cones the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.
Volume of cone can be given as,
[tex]V=\dfrac{1}{3}\pi r^2h[/tex]
Here, (r) is the radius of the base of the cone and (h) is the height of the cone.
The height of the cone is 6.5 cm and the radius is 2.5 cm. Put the values in the above formula,
[tex]V=\dfrac{1}{3}\pi r^2h\\V=\dfrac{1}{3}\pi (2.5)^2(6.5)\\V=\dfrac{1}{3}\pi (6.25)^2(6.5)\\V=\dfrac{40.625\pi }{3}\\V\approx42.5\rm\;cm^3[/tex]
The surface area of cone can be find out by the following formula,
[tex]A=\pi r(r+\sqrt{h^2+r^2})[/tex]
Again put the values in this formula,
[tex]A=\pi \times2.5(2.5+\sqrt{(6.5)^2+(2.5)^2})\\A=\pi \times2.5(2.5+\sqrt{48.5})\\A=\pi \times2.5(2.5+6.96)\\A=\pi \times2.5(9.46)\\A=74.33\rm\; cm^2[/tex]
Thus, the surface area of the cone shown in the figure, for which Jane incorrectly finds the volume, is 74.33 cm².

Find the volume of the sphere. Round your answer to the nearest tenth.
Answers
Answer:
See below.
Step-by-step explanation:
The formula for the volume of a sphere
= 4/3 π r^3 where r = the radius.
So for number 1:
V = 4/3 π (5)^3
= 523 .60 mm^3 to nearest hundredth.
The others are solved in exactly the same way except where the diameter is given as in number 4 and 5 you get the radius r by dividing the diameter by 2. So in number 4, r = 30/2 = 15.

The answer is: C
Step-by-step explanation: So they tell you that each pencil cost the same as another and the same applies to the journals. With this information you know that you're spending the same for each one, meaning you can multiply the amount you bought by the price and get your total. So, as an example: Mr. Bowden bought 18 journals, in our situation journals cost *J*. So 18 multiplied by *J* would be our total for the journals Mr. Bowden bought. the same applies to pencils, and so Mr. Bowden bought 40 pencils, and each pencil costs *P*. We can multiply 40 and *P* to figure out what the pencils in total for Mr. Bowden cost. We can then add the total for journals and pencils for Mr. Bowden and get $95.42. I hope this helps :)
