An exponent is often referred to as a power of 10, for instance, [tex]\sf 6\boxed{^7}[/tex], as the exponent is highlighted. A number can only become a power of 10 under certain circumstances in an expression, on the other hand, you have exponents alone in expressions like "45² + x", the exponent was assigned to a number and that means that we multiply that number by itself that number of times. Logically speaking, it's impossible for a number alone to be a power of 10 or to become one out of the blue, a power of 10 is assigned into an expression and before a whole number before you start working on it, which is the equation.

The two representations are:

x > 5

A number line with an open circle at 5 and a line that points to the right.

We start with the inequality:

-3(2x - 5) < 5*(2 - x)

First, we need to solve this for x, expanding both sides we get:

-6x + 15 < 10 - 5x

Now we move the terms with x to the right side and the terms without to the left side.

15 - 10 < 6x - 5x

5 < x

This is a representation of the inequality.

The other will be a graph, to graph this on a number line we need to do an open circle at x = 5, and shade the region to the right (because x is larger than 5).

You find the common multiple and then distribute.

The actual width of the field 80 yard. when proportion is 3 : 2.

What in mathematics is a proportion?

A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)

We have the proportion  

                            3/2 = 120/w

where in the numerator are the length and in the denominators the width of the field.

Now ,                        3 . w = 120 . 2

                                  3w = 240

                                    w = 80

let Irene's share be x and Charlie's share be y

x=2y-8

x+y=$47.50

x=$47.50-y

$47.50-y=2y-$8

$47.50+$8=2y+y

$55.50=3y

y=$55.50/3

y=$18.50

x=$47.50-$18.50

x=$29

Answer:

Irene's share = 29

Charlie's share = 18.5

Step-by-step explanation:

R bill = 47.5

Irene's share = (2 × Charlie's share )-8

Irene's share = y

Charlie's share = x

bill = x + y = 47.5

y = 2x -8

This is further explained below.

Generally, Expressions are considered to be equivalent if their function is the same despite their appearance being distinct.

If two algebraic expressions are equivalent to one another, then those two expressions will provide the same result when we use the same value for the variable in each expression.

In conclusion,

Firstly, we consider what Dave saves in one week will be,

Since $24 Dave’s after 3 weeks we have

One week =24/3

the rate of change of the linear equation in the table is 120.

Remember that for any linear equation with an slope (also called rate of change) s and it passes through the points (a, b) and (c, d), then the slope can be written as:

s = (d - b)/(c - a)

Using that relation and the first two points on the table (0.5, 60) and (1.5, 180)

We get that the rate of change is:

s = (180 - 60)/(1.5 - 0.5) = 120

Total number of hours both worked last month is; 28.8 hours

Let the number of hours that Herold worked last month be x. Thus, number of hours that Marley worked = 16 + x

Now, we are told that Marley worked 7 hours for every 2 hours that Herold worked. Thus;

(16 + x)/x = 7/2

Cross multiply to get;

2(16 + x) = 7x

32 + 2x = 7x

7x - 2x = 32

x = 32/5

x = 6.4 hours

Thus, total hours Marley worked = 16 + 6.4 = 22.4 hours

Total number of hours both worked last month = 22.4 + 6.4 = 28.8 hours

The sum to infinity of the terms of this sequence is -36/5

The given parameters are

T3 = -1/6

T6 = -1/1296

The nth term of a geometric sequence is

Tn = a * r^(n-1)

So, we have

T3 = ar^2

T6 = ar^5

Divide both equations

T6/T3 = ar^5/ar^2

Evaluate the quotient

T6/T3 = r^3

Substitute T3 = -1/6 and T6 = -1/1296 in T6/T3 = r^3

(-1/1296)/(-1/6) = r^3

Evaluate the quotient

1/216 = r^3

Take the cube root of both sides

r =1/6

Substitute r =1/6 in T3 = ar^2

T3 = a(1/6)^2

This gives

T3 = a/36

Substitute T3 = -1/6 in T3 = a/36

a/36 = -1/6

This gives

a = -6

The sum to infinity of the terms of this sequence is

S = a/(1 - r)

This gives

S = -6/(1 - 1/6)

This gives

S = -6/(5/6)

Evaluate

S = -36/5

Hence, the sum to infinity of the terms of this sequence is -36/5

The total area of the land that the developer is considering to buy is 49,500 yards².

We are given a triangular plot of land having the dimensions as:

Base = b = 550 yards

Height = h = 180 yards.

We need to find the area occupied by the triangular plot.

Area of a triangle refers to the space occupied by the shape or object.

Area = 1 / 2 × b × h

Substituting the values in the formula, we get that:

Area = 1 / 2 × 550 yards × 180 yards

Area = 550 yards × 90 yards

Area = 49,500 yards²

Answer:

C. 49,500 yd2

Step-by-step explanation:

good luck

Answer:

See below

Step-by-step explanation:

From 2 minutes to 5 minutes the pump puts in (200-110) = 90 gallons ...in 3 minutes....so the rate of the pump is    30 gal / min

   at two minutes the pump has put in 30 x 2 = 60 gallons......so there was 50 gallons in the tank to start ( 50 + 60 = 110)

the equation becomes :

   G = 50  +  30 t    

               where t = minutes

   and 50 is the initial volume in the tank

For 13 minutes      G = 50 + 30 (13) = 440 gallons

For 890 gallons      890 = 50 + 30 t

                                840 = 30 t

                                   t = 28  minutes

t intercept occurs when  G = 0

                         0 = 50 + 30 t

                             t = - 5/3   minute    <====this is the amount of time before measurements were taken.....or the time for the pump put in 50 gallons before the  start
