Based on the given equation, the change of subject of the equation to M is given by M = 10L - 5/2g + 130

Changing the subject of formula of an equation is the working out of a particular variable from the list of variables in the formula. The variable is either denoted with letter or symbol.

M/5 - 26 = 2L- 1/2g

Where,

M/5 - 26 = 2L- 1/2g

M/5 = 2L - 1/2g + 26

M = 5(2L - 1/2g + 26)

M = 10L - 5/2g + 130

Therefore, the solving for M in the equation will give M = 10L - 5/2g + 130

Answer:

x = 3

Step-by-step explanation:

3x + 2 = 11

3x = 11 - 2

3x = 9

x = 9/3

x = 3

Answer:

Separate the x and the numbers on each side and solve.

3x + 2 = 11

3x = 9

x = 3

Answer:

n < - 1

Step-by-step explanation:

- 2(n - 4.5) > 11 ← distribute parenthesis on left side

- 2n + 9 > 11 ( subtract 9 from both sides )

- 2n > 2

divide both sides by - 2, reversing the symbol as a result of dividing by a negative quantity.

n < - 1

Answer:

n < -1

Step-by-step explanation:

-2(n -4.5) > 11 (multiply the contents within the bracket by -2.)

-2n + 9 > 11 (- × - = +)

-2n > 11 - 9 [ like terms have to be with each other (transposing); and when u transpose a number it changes signs.]

-2n > 2 (divide both sides by negative 2)

n < -1 (sign changes as a reslut of the negative division)

• [tex]a^{0}[/tex] = 1 , then

[tex](5x)^{0}[/tex] = 1

Answer:

-1

Step-by-step explanation:

First combine like terms on the right side (5x-10x) to get -5x +4

6-3x=-5x+4

then move the -5x over to get 2x because you would add the -5x to the -3x.

6+2x= 4

then subtract 6 on both sides.

2x=-2

to make your final answer -1.

Step-by-step explanation:

After completing 6 week and 8 days, the amount in the bank account will be $280.

The initial balance in the bank account = $60.

Allowance deposit per week = $7.

Paycheck deposit per week = $25.

Let 'w' be the number of week.

Th equation of the total amount 'b' after 'w' week becomes;

b = 60 + (25+7)w

As, the total amount becomes $280, after the week .

Put b = 280 in equation and find w.

280 = 60 + (25+7)w

Simplifying;

220 = 32w

w = 6.875

Step-by-step explanation:

For Arithmetic Sequence

Tn = a + (n -- 1)d

Where Tn = the no of nth term

a = First number

n = nth term

d = common difference

a = --27, T2 = --21

d = second term -- first term

d = --27 -- (--21)

d = --27 + 21 = --6

a = --27, n = 62, d = --6, T62 = ?

Tn = a + (n -- 1)d

T62 = --27 + (62 -- 1)×--6

T62 = --27 + (61 × --6)

T62 = --27 + (--366)

T62 = --27 -- 366

T62 = --393

Answer:

A square pyramid is composed of an eight-sided square base, four triangular sides, five vertices, and five vertices. This pyramid has a square base with a peak at the top. The fact that a square pyramid is a polyhedron was noted.

Step-by-step explanation:

The three-dimensional geometric shape of a square pyramid has a square base and four triangular sides that are joined at the vertex. Five facets make up its polyhedron shape (pentahedron). Four triangles joined at the vertex and a square base make up a square pyramid. Three sides, a square base, and a central vertex characterize the triangle side faces. The tallest point of the pyramid is known as its "apex." The base is represented by the bottom square. Faces are the three triangular vertices of the triangle. When viewed from the bottom up, a pentahedron is a five-sided, three-dimensional shape that resembles a square pyramid.

Answer:

h(x) = 9x-18 is the correct inverse function

Step-by-step explanation:

f(x) -> y (first we need to rewrite the equation with y)

y= 1/9x+2 (next we need to solve for x)

y=1/9x

-2 -2  (subtract 2 from both sides)

y-2= 1/9x (multiply 9 on both sides

9y-18= x (and lastly switch back x and y)

y = 9x - 18 (if a real equation than write h(x) or [tex]f(x)^{-1}[/tex], if not real equation keep it in y)

h(x) = 9x-18

The mean distance, μ, If 5% of balls go farther than 70 feet is; μ = 68.032

We know that the formula to find the z-score is;

z = (x' - μ)/σ

where;

z is z-score

x' is sample mean

μ is population mean

σ is standard deviation

We are given;

σ = standard deviation = 1.2

x' = sample mean = 70 ft

Now, the z-score that produces a p-value of 0.05 or 5% is; z = 1.64

Thus;

1.64 =  (70 - μ)/1.2

μ = 70 - (1.64 * 1.2)

What is angle of depression?
The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line.

Given data ,

we have Angle of depression = 35°

Base distance D = 905 ft

Let the vertical distance be H

To calculate the vertical distance H of the balloon above the ground , we use the angle of depression and the base distance.

Therefore , using the trigonometric identities ,

sin = Opposite / Hypotenuse

cos = Adjacent / Hypotenuse

tan = Opposite / Adjacent

So , tan  Ф = tan 35°

                  = H / D

      tan 35°= H / 905

H = tan 35° x 905 ft

H = 0.7002075 x 905

H = 633.7 ft

 x = 5.33333333333

Step-by-step explanation:

3x-5=11

   +5   +5

3x= 16

3      3      

u need to separate the 3x

so u use the opposite operation on - 5

add +5 on both sides

-5 plus 5 cancel each other

add 11 to 5 and that is 16

bring them down and divide both by 3

and ur 3 cancel each other,

now divide 16 by 3

and u get  x = 5.33333333333

The speed of the walker is 16.67 miles per hour.

The speed of the cyclist is 25 miles per hour.

Let the speed of a walker = x

Biker's speed = 1.5x

Their relative speed will be:

= 1.5x - x = 0.5x

Distance between them = 12.5 miles

Time taken = 1.5 hours.

It should be noted that distance will be:

= Speed × Time

12.5 = 1.5 × 0.5x

Divide through to get x

12.5 = 0.75x

x = 16.67 miles per hour.

Speed of cyclist = 16.67 × 1.5 = 25 miles per hour.
