There are a number of ways to do this type of problem. One way is to divide the figure as shown in the diagram below. See the attached image.

I'm splitting the irregular shape into two rectangles and a triangle.

The upper rectangle is 10 miles by 9 miles to get an area of 10*9 = 90 square miles. Let A = 90 so we can use it later.

The lower rectangle is 4 miles by 19 miles. Its area is 4*19 = 76 square miles. Let B = 76.

The total vertical height of the figure is 9+4+10 = 23 miles.

Notice along the column that has "8 miles" up top over "9 miles" down below, we have a gap of some distance which I'll call x. This x adds to 8 and 9 to get the 23 mentioned.

x+8+9 = 23

x+17 = 23

x = 23-17

x = 6

This helps find the height of the triangle which is 9+x = 9+6 = 15 miles.

The triangle has a base of 9 miles.

The area of the triangle is base*height/2 = 9*15/2 = 135/2 = 67.5 square miles. Let C = 67.5

--------------

We found that:

The total area is: A+B+C = 90+76+67.5 = 233.5 square miles.

Answer:

c=-2.5s

Step-by-step explanation:

The equation modeling the change in elevation c after s seconds is

c = -2.5s

Given,

A mountain climber descends a cliff at a rate of 2.5 ft/second.

We need to write an equation modeling the change in elevation c after s seconds.

Elevation means going up so we take it as a positive distance.

Descent means going down so we take it as a negative distance.

Find the rate at which the climber descents.

2.5 ft = 1 second

Find the equation that represents the descents c in seconds.

We have,

2.5 ft = 1 second

So,

s x 2.5 ft = s x 1 seconds

2.5 s ft = s seconds

This means,

In s seconds we will have a 2.5s distance descended.

We can write this as an equation:

c = change in elevation

c = - 2.5s

Thus the equation modeling the change in elevation c after s seconds is

c = -2.5s

Answer:

  9.2 m

Step-by-step explanation:

The right triangle model is shown in the attachment. The lengths 6 m and 7 m are the legs of the triangle, and the requested distance is the hypotenuse. The given Pythagorean theorem equation can be used to find the desired distance:

  c² = a² +b²

  c² = 7² +6² = 49 +36 = 85

  c = √85 ≈ 9.2

Answer:

12

Step-by-step explanation:

Since there are 6 packs in all, and a total of 72 cards, we can multiply 6×12=72

There were 12 cards in each pack if they have 72 cards in all.

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Lori and Jayden crack open six packs of baseball cards. They have a total of 72 cards.

As per the given question, the required solution would be as;

Lori and Jayden have 6 packs × c cards/pack =  cards in total.

This means that there are c = 72 cards / 6 packs = 12 cards in each pack.

Therefore, there were 12 cards in each pack.

Step-by-step explanation:

Answer:

1/9 is smaller than 1/6, so it takes more amounts of 1/9 to make make a fraction equal to 1/3

It takes more 1/9 than 1/6 to make a fraction equivalent to 1/3.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

To make a fraction equivalent to 1/3, we need to multiply both the numerator and the denominator by the same non-zero constant. Let's call this constant "x". Therefore, the equivalent fractions are:

1/3 = (x1)/(x3)

To compare how many 1/9s and 1/6s are needed to create this fraction, we need to find the value of "x" that will make the denominators of 1/9 and 1/6 equal to the denominator of 1/3, which is 3.

For 1/9, we can find x as follows:

1/9 = (x1)/(x9)

Multiplying both sides by 3, we get:

3/9 = (x3)/(x9)

Simplifying, we get:

1/3 = x/9

Multiplying both sides by 9, we get,

x = 3

Therefore, to make a fraction equivalent to 1/3 using 1/9, we need to multiply both the numerator and denominator by 3.

Now let's look at 1/6. We can find x as follows:

1/6 = (x1)/(x6)

Multiplying both sides by 2, we get:

2/12 = (x2)/(x12)

Simplifying, we get:

1/6 = x/12

Multiplying both sides by 12, we get:

x = 2

Therefore, to make a fraction equivalent to 1/3 using 1/6, we need to multiply both the numerator and denominator by 2.

The Consumer Price Index for the year 2 be 116.11.

This is calculated by adding together a sampling of product prices from a previous year.

We then add together the current prices of the same products and divide the total of current prices by the old prices, then multiply the result by 100.

Given data

Year 1 = $9

Year 2 = $10.45

Year 2 / Year 1 = $10.45 / $9.00

Year 2 / Year 1= 1.6111

CPI for year 2 = 1.61 x 100

CPI for year 2 = 116.11

Therefore, the Option D is correct.

Answer:

Total Population = Young & Institutionalized + Working Age Population

Working-Age Population = Labor Force + Not in the Labor Force

Labor Force = Employed + Unemployed

Total population = 400

Working Age Population = 300

Young & Institutionalized = 100

Not in Labor Force = 100

Labor Force = 200

Employed = 150

Unemployed = 50

Employment-population ratio = (Employed ÷ Working Age Population) x 100%

                                                 = (150 ÷ 300) × 100%

                                                 = 50%

Labor force participation rate = (Labor Force ÷ Working Age Population) x 100%

                                                 = (200 ÷ 300) × 100%

                                                 = 66.7% (nearest tenth)

Unemployment rate = (Unemployed ÷ Labor Force) x 100%

                                  = (50 ÷ 200) x 100%

                                  = 25%

y=3√3

Use trig ratios

Answer:

x = 3sqr3, y = 9

Step-by-step explanation:

Use SOH CAH TOA, to solve this.

Here I know the hypotenuse, so I could use either SOH either CAH or both to find the 2 unknowns.

To find y, I would use SOH, which is Sin(angle) = opposite/hypotenuse.

When I rearrange it, I get Sin(angle)*hypotenuse = opposite. Now let's fill in with the values to give:

Sin(30)*6sqr3 = 3sqr3

And then to find x, let's use CAH, which is Cos(angle) = adjacent/hypotenuse.

Rearrange it to get Cos(angle)*hypotenuse = adjacent. This gives us a side x with a value of:

Cos(30)*6sqr3 = 9
