Use Ep=mgh
Ep- gravitational potential energy (Joules)
m- mass (kg)
g- acceleration due to gravity(9.8m/s^2 on earth)
h-height above ground (metres)


1.Ep=mgh
Ep= (0.1)(9.8)(4)
Ep=3.92 Joules

2.Ep=mgh
Ep=2(9.8)(3)
Ep=58.8 Joules

Total surface area??

Answers

Answer:

total area = 207 cm²

Step-by-step explanation:

base area = 9 x 9 = 81

side area = 1/2(9)(7) = 31.5 x 4 (for 4 sides) = 126

81 + 126 = 207 cm²

Raymond needs to cover the entire surface area of the square based pyramid with paper what is the minimum amount of paper he will need

Answers

Answer: 408 sq ft

Step-by-step explanation: You would need to use the surface area formula SA = 1/2LP + B. Note that L is the slant height, P is the perimeter of the base, and B is the area of the base. 11 is the slant height as shown in the image above, p is 48 since you add 12 + 12 + 12 + 12, and the area of the square will be 144 since 12*12 = 144. Once you substitute the numbers in their correct place, you should get SA = 1/2 (11)(48)+144 which gives you 408 sq ft. Hope this helps!

Answers

Answer:

5 1/4 ; 6 ; 6 3/4

Step-by-step explanation:

Using the nth term of an arithmetic progression relation.

an = a + (n - 1)d

First term, a = 4 3/4

Common difference, d = 1/4

3 rd term ; n = 3

a3 = 4 3/4 + (3 - 1)1/4

a3 = 4 3/4 + 2*1/4

a3 = 4 3/4 + 1/2

a3 = 5 1/4

6th term ; n = 6

a6 = 4 3/4 + (6 - 1)1/4

a6 = 4 3/4 + 5*1/4

a6 = 4 3/4 + 5/4

a6 = 6

9 th term ; n = 3

a9 = 4 3/4 + (9 - 1)1/4

a9 = 4 3/4 + 8*1/4

a9 = 4 3/4 + 2

a9 = 6 3/4

The product of two numbers is negative. What conclusion can you draw about the sign of the quotient of the same numbers? *​

Answers

According to the law of signs for division, the quotient of 2 numbers of different sign is negative

Answer:

The quotient is negative.

Step-by-step explanation:

The rules of signs for multiplication and division of two numbers are the same.

If you multiply or divide two numbers with the same sign (both positive or both negative), the answer is positive.

If you multiply or divide two numbers with different signs (one positive and one negative), then the answer is negative.

Since the product is negative, then the quotient is also negative.

Answer: The quotient is negative.

Step-by-step explanation:

Hello There!

N = Nickels and D = Dimes

The total amount of nickels and dimes is 27

so d + n = 27

or d = 27 - n

or n = 27 - d

It says that the amount of nickels she has is 3 times the amount of dimes minus 1

so

n = 3d - 1

so looking at the information above we can conclude that the answer is D

The diagram shows quadrilateral MNPQ.

Quadrilateral M N P Q is shown. Sides N P and M Q are parallel. Angles P and Q are right angles. The length of M N is 10, the length of N P is 3, and the length of P Q is 6.

What is the length of line segment MQ?
8 units
10 units
11 units
15 units

Answers

Answer:

The answer is 11 units

Step-by-step explanation:

I just took the test, plus if you were to lay the side MN down to next to MQ, it would be similar but, a little be shorter. Also if you were to think of it, 8 units would be too short and 15 units would be too long, 10 units would of made MQ look the same length as MN, but MQ was longer just by a bit. Thus, makes 11 units the answer.

Hopes this helps!

For the given quadrilateral MNPQ, the length of MQ is 11 units.

Therefore, the option C is the correct answer.

Given that a quadrilateral MNPQ, with sides NP and MQ are parallel, ∠P = ∠Q = 90°, MN = 10, NP = 3 and PQ = 6.

We need to find the length of side MQ,

MQ = MR + RQ............(i) [segment addition property]

To find MR and RQ, we will have to do a construction in the figure given,

(Refer to the diagram attached)

Join the segment NR, that will be equal and parallel to PQ and perpendicular to MQ.

So, we get NPQR as a rectangle, according to the property of a rectangle its opposite sides are equal,

So, we get,

QR = 3 and NR = 6.

Also, we have a right triangle MNR, where MN is the hypotenuse,

Using the Pythagoras theorem, we can find the length of MR,

MR² = MN² - NR²

MR = √(10² - 6²)

MR = √(100 - 36)

MR = √64

MR = 8

Putting the values of MR and QR in equation (i), we get,

MQ = MR + RQ

MQ = 8 + 3

MQ = 11

Hence the length of MQ is 11 units.

The cone and cylinder above have the same radius and height. The volume of the cylinder is 48 cm3. What is the volume of the cone?
A.
24 cm3
B.
16 cm3
C.

Answers

Answer:

Option B (16 cm³)

Step-by-step explanation:

GIVEN :-

Both cone and cylinder have same radius and height.Volume of cylinder = 48 cm³

TO FIND :-

Volume of cone

FACTS TO KNOW BEFORE SOLVING :-

Volume of a cylinder having radius 'r' and height 'h' is  [tex]\pi r^{2} h[/tex]Volume of a cone having radius 'r' and height 'h' is  [tex]\frac{1}{3} \pi r^{2} h[/tex]

Hence ,

Volume of cylinder = Thrice the volume of cone
