Answer:

[tex]x=\frac{5}{k}[/tex]

Step-by-step explanation:

Given expression is,

[tex]\text{log}_{3^k}243=x[/tex]

By using the law of logarithm,

[tex](3^k)^x=243[/tex]

[tex]3^{kx}=243[/tex]

[tex]3^{kx}=3^5[/tex]

By comparing exponents on both the sides of the equation,

[tex]kx=5[/tex]

[tex]x=\frac{5}{k}[/tex]

Therefore, [tex]x=\frac{5}{k}[/tex] will be the answer.

Answer:

number 1:area is 30 , perimeter is 22

number 2:area is 450 perimeter is 29

Step-by-step explanation:

Answer:

1 = 30, 22. 2 = 45, 33.

Step-by-step explanation:

For step 1, multiply the numbers to get the area, then double them and add them all to get the perimeter.

For step 2, multiply the two sets of numbers, 5 and 3, and 6 and 5, and add them. For the perimeter do the same as step 1.

Answer:

maybe 14/20

Step-by-step explanation:

Answer:

10000

Step-by-step explanation:

Let the number = x

Square root of x divided by 5 equals 20

√x / 5 = 20

Using cross multiplication

√x = 20 * 5

√x = 100

Take the square of both sides

(√x)² = 100²

x = 10000

Therefore, the number is 10000

Answer:

[tex]104in^{2}[/tex]

Step-by-step explanation:

area of a triangle is just (b)(h)/2

(13)(16)/2

208/2

104 in squared

Answer:

104ft²

Step-by-step explanation:

formula for area of a triangle = [tex]A=\frac{bh}{2}[/tex]

where b = base length and h = height

The triangle shown has a base length of 16 ft and a height of 13 ft

Using this information we plug in the values into the formula

[tex]A=\frac{16*13}{2}\\16*13=208\\\frac{208}{2} =104\\A=104ft^2[/tex]

Hence, the answer is 104ft²

Answer:

GL = square root of 2 = √2

Step-by-step explanation:

Given: GHJK is a square and its diagonals intersect at L

GJ and HK are its two diagonals.

We know that in a square diagonals bisect each other and if length of side is a, then length of its diagonal = √2 a.

Therefore, GJ=HK = √2×2

Since, diagonal intersect at L , L is mid point of GJ and HK

Therefore, GL = √2×2/2 = √2

Hence, GL = square root of 2

the dimensions of the rectangle are 9 and 3

Step-by-step explanation:

Length of the wooden dowel rod = 8/15 of a yard

Number of pieces = 24

What is the length of each piece of dowel rod?

Length of each piece of dowel rod = Total length of wooden dowel rod / number of pieces

= 8/15 ÷ 24

= 8/15 × 1/24

= (8*1) / (15*24)

= 8/360

= 1/45

Length of each piece of dowel rod = 1/45 of a yard

Give the guy above me brainliest tho :)

The height of the rhombus is equal to 9 centimeters.

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

here, we have,

To calculate the height of the rhombus, we will follow the steps below;

write the formula for calculating the area of a rhombus

area of a rhombus = b × h

where h is the height of the rhombus and b is the base of the rhombus

From the question given,  area of the rhombus = 12 square centimeters  

and length of sides of the rhombus is 8 centimeters.

we can now proceed to insert the values into the formula and then solve for h

area of a rhombus = b × h

i.e.  12 = 4 × h

Divide both-side of the equation by 4

12/4  =  4/4 × h

3 =  1× h

3 = h

h =3 centimeters

The height of the rhombus is equal to 3centimeters.

Answer:

17.5

Step-by-step explanation:

y=kx

35 = k(140)

k = 0.25

(k is constant of proportionality)

y = (0.25)(70)

y=17.5

Answer:

Hello There!!

Step-by-step explanation:

I think it is the second option as you use the formula for finding out the area of a triangle which is b×h/2 so 18×6=108 then divide by 2 or half it which gets the answer of 54mi^2.

hope this helps,have a great day!!

Answer:

Step-by-step explanation:

Number needed is 4² = 16

Answer:

Solution given:

x² + 8x =6

x²+2.x.4+4²-4²=6

(x+4)²=6+16

(x+4)²=22

so

no needed is 4² or 16.

Answer:

4x=-16

x=-4 is your answer

Answer:A) x = -4

Additive inverse -3 to both sides 4x=-16

The divide both sides by 4, x=-4
