Which expression represents the perimeter of a rhombus with diagonal lengths 8a and 10a?

Answers

Answer 1

Answer:

4a[tex]\sqrt{x}[/tex]41

Step-by-step explanation:

12*2+9x2= Perimeter.

Answer 2

The perimeter P of rhombus is given as

[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]

The diagonals of rhombus bisect each other at right angles and it has same perimeter as that of a square.

From this property stated above we can formulate  side of rhombus is below in equation (1)

Side and  diagonals of rhombus have following relation

[tex]\rm Let \; the \; side \; of\; rhombus = s\\Length\; of \; first \; diagonal = 8a\\ Length\; of \; second \; diagonal = 10a\\\\According \; to \; the \; identity\; for\; area \; of\; rhombus \\ s^2 = (p/2)^2 +(q/2)^2 ....(1) \\where \; p \; and\; q \; are\; the \; diagonals.[/tex]

so

[tex]\rm s^2 = (10a/2)^2 + (8a/2)^2\\s^2 = 25a^2 + 16a^2 = 41 a^2 \\s= \sqrt{41}a ......(2)[/tex]

Equation (2) represents side of rhombus

So the perimeter P of rhombus is given as

[tex]\rm P = 4\times s[/tex]

[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]

The perimeter P of rhombus is given as

[tex]\rm\bold{ P = 4\sqrt{41}a }[/tex]

The total is 120. 8 have a box meaning 112 do not have a box. The question is asking about those without a box, so 112 will be used. 112/120. Simply by dividing each the numerator and denominator, in this case by 8. The fraction left is 14/15

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

calculate

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!

D.
144 cm3

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

[OR]

Volume of cone = One third of volume of cylinder

PROCEDURE :-

Volume of cone = [tex]\frac{1}{3} (Volume \: of \: cylinder) = \frac{48}{3} = 16cm^3[/tex]

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.

Given:

The function is:

To find:

The value of [tex]\dfrac{dy}{dx}[/tex].

Solution:

We have,

[tex]y=-\dfrac{3\sqrt{x^5}}{4}[/tex]

It can be written as

[tex]y=-\dfrac{3}{4}x^{\frac{5}{2}}[/tex]        [tex][\because \sqrt[n]x=x^\frac{1}{n}][/tex]

Differentiate with respect to x.

[tex]\dfrac{dy}{dx}=-\dfrac{3}{4}\times \dfrac{5}{2}x^{\frac{5}{2}-1}[/tex]       [tex][\because \dfrac{d}{dx}x^n=nx^{n-1}][/tex]

[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{5-2}{2}}[/tex]

[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}x^{\frac{3}{2}}[/tex]

[tex]\dfrac{dy}{dx}=-\dfrac{15}{8}\sqrt{x^3}[/tex]

Therefore, the value of [tex]\dfrac{dy}{dx}[/tex] is [tex]-\dfrac{15}{8}\sqrt{x^3}[/tex].

Start at 4 3/4 and count on steps of 1/4. If 4 3/4 is the first number in the sequence write down the 3rd number and the 6th number and the 9th number

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
