We are given a trapezoid and we are asked to determine one of its angles. To do that we need to have into account that the following angles are equal:

Also, the sum of two different angles must be equal to 180, therefore, we have the following relationship:

Replacing the value of angle W:

Subtracting 112 to both sides:

Therefore, the measure of angle Z is 68.

The actual distance between city c and city d represented by 2.38 feet on the map as required in the task content is; 700 miles.

It follows from the task content that the actual distance between city c and city d be determined according to the map's scale factor given.

It follows from the task content that the distance between cities a and b which is 500 miles is represented by 1.7 feet on the map;

1.7 feet ===== 500 miles

Hence, let x = the actual distance between the cities c and d represented by 2.38 on the map is; so that we have;

1.7 feet ====== 500 miles

2.38 feet ====== x miles.

x = (500 × 2.38)/1.7

x = 700 miles.

Therefore, the actual distance between the two cities c and d is; 700 miles.

The amount of money Landon will make in 1 hour is $12 and he needs to work for 13 hours to make $156.

The amount of money he will make in 1 hour can be calculated by using division.

It can be determined by dividing the total amount earned by him by the total number of hours he worked yesterday. Therefore;

money earned in 1 hour = total amount earned ÷ total number of hours

money earned in 1 hour = 48 ÷ 4

money earned in 1 hour = $12

Now we can calculate the number of hours he needs to work at the movie theater to make $156 by dividing the desired amount by the amount earned in one hour. Therefore;

number of hours required = 156 / 12

number of hours required = 13

Hence, Landon will make $12 in one hour and he will need to work 13 hours to make $156

A function with the formula f(x) = ax + b, where a and b are real values, is referred to as a linear function. Here, a stands for the line's gradient, and b for the y-axis intercept (which is sometimes called the vertical intercept).

The rate of change of y with respect to x, can be calculated utilizing any two of the pairs of values of the table, say, (3, -5) and (7, -2).

Rate of change [tex]$=\frac{y_2-y_1}{x_2-x_1}$[/tex]

The approximate value of the expression given will be equal to -6.3.

An approximation may be defined bringing the value of a certain entity which is almost similar, but not exactly equal to the correct value. The expression can be written as −12 + √32. The value of √32 can be written as 5.656. Since, after decimal 6 to the right of 5 is greater than 5 so to the nearest tenth, we can write as 5.66. Therefore, √32 = 5.66

For the required value of the expression we can write,

−12 + √32

Putting the value of √32 = 5.66 in the expression we get

-12 + √32 = -12 + 5.66

After solving we get

⇒ -12 + √32 = -6.34

To the nearest tenth it will be -6.3.

in the question ,

it is given that ,

On the map  [tex]1\frac{1}{2}[/tex]  miles is equal to  [tex]1\frac{7}{8}[/tex] inches  .

we first convert the mixed fraction to normal fractions ,

we get

[tex]1\frac{1}{2}[/tex]  miles = (1*2+1)/2 = 3/2 miles

and

[tex]1\frac{7}{8}[/tex] inches = (8+7)/8 = 15/8 inches

So, the statement becomes

On the map  3/2  miles is equal to  15/8 inches .

So  1 mile = (15/8)/(3/2) = (15*2)/(8*3) = 30/24 = 5/4

so , the unite rate is 5/4 inches per mile .

given the road B is 15 miles long .

and the unit rate is 5/4 .

so 15 miles = 15 *(5/4) = 75/4 = 18.75 inches

Seven people sharing the rent would make the cost $120 per person.

When two quantities are inversely proportional, that is, when an increase in one causes a decrease in the other and vice versa, they are said to be inversely proportional.

The general equation for inverse variation is y = k/x, where k is the proportionality constant and x and y are two variables.

Given:

The price paid by Four friends on a ski trip to share the rent of a cabin = $210

The cost per person varies inversely with the number of persons.

Let the cost be C and the number of persons be n,

C ∝ 1/n

So, the equation becomes, k = Cn.

Putting the values in the equation we obtain the value of k,

k = 210×4 = 840

We have to find the number of people sharing the rent that would make the cost $120 per person.

Using the equation,

k = Cn

840 = 120 × n

n = 840/120 = 7

Therefore, seven people sharing the rent would make the cost $120 per person.

1. Common ratio of the G.P is 50

2. First term of the G.P is -100

3. Sum of the 8th term is 250.

Given,

In a Geometric progression,

7th term is 16 times the 3rd term

Sum of 2nd and 6th term is 102

Common ratio is positive.

Now,

Take a as first term.

r as common ratio

Then,

2nd term = a + r

6th term = a + 5r

So,

a + r + a + 5r = 102

Then,

2a + 6r = 102

2a = 102 - 6r

a = (102 - 6r) / 2

Now,

1. Common ratio:

Consider any term,

Here, 3rd term = a + 2r

Substitute a here.

a + 2r =  (102 - 6r) / 2 + 2r

102 - 6r + 4r = 2

102 - 2 = 6r - 4r

100 = 2r

r = 100/2 = 50

That is,

The common ratio of the G.P is 50.

2. First term:

Consider,

7th term is 16 times the 3rd term

That is,

3rd term = a + 2r

7th term = 16(a + 2r)

r = 50

Then,

a + 50 × 2 = 16(a + 50 × 2)

a + 100 = 16(a + 100)

a + 100 = 16a + 1600

100 - 1600 = 16a - a

15a = -1500

a = -1500/15

a = -100

Therefore,

The first term of the G.P is -100

3. Sum of the 8th term.

8th term = a + 7r = -100 + 7 × 50 = -100 + 350 = 250

That is,

The sum of the 8th term is 250.

Multiplying both sides by 64 cancels on the left64 × (X/64) = (9/8) × 64

X = (9/8) × 64Then solving for X X = 64 × (9/8)X = 72
