Answer:

ok first you'll have to subtract

6 from 22 = 16

so now easy

you'll say

16+3 and you'll have your answer

Answer:

Step-by-step explanation:

ΘΘ + 6 = 22

Factor on the left.

2(Θ + 3) = 22

Divide both sides by 2.

Θ + 3 = 11

The interpretation of the straight line graph of the gallons of gas to distance in miles are as follows;

(a) After 100 miles, the equation for the graph and the graph indicates that Linda's car will have more gas

Linda's car will have 1 gallon more gas than Shen's car.

(b) Linda and Shen will have the same amount of gas in their cars after 150 miles

The graph indicates that Shen's car will have less gas than Linda's car before reaching 150 miles

A straight line graph is a graph of a linear equation.

The points on the graphs are;

Linda; (0, 14), (150, 8)

Shen; (0, 11), (150, 8)

The equation for the amount of gas remaining in Linda's car can be found as follows;

Slope of the line = (8 - 14)/(150 - 0) = -6/150 = -1/25 = -0.004

Equation of the line is therefore;

y - 14 = (-1/25)(x - 0)

The slope of the graph of the equation of Shen's car = (8 - 11)/(150 - 0) = -0.02

The equation of the line is; y - 11 = -0.02·x

After 100 miles we get;

Gas left in Linda's car = -0.04 × 100 + 14 = 10

Gas left in Shen's car = -0.02 × 100 + 11 = 9

Therefore, Linda's car will have more gas after 100 miles

Her car will have 10 gallons of gas

(b) From the graph, at the point x = 150, the tanks of Linda and Shen will contain the same amount of gas

If the miles driven is less than 150 miles, the graph indicates that Shen's car will have less gas than Linda's car

Answer: $5.50

Step-by-step explanation:

$275 x 2% = 550

550/100 = 5.5

The salesperson makes $5.50 in commission.

30.54cm is the length of the vertical leg.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

In a right angled triangle  the horizontal leg has a measure of 42.7 centimeters(cm).

The hypotenuse has a measure of 52.5cm.

We need to find the measure of the vertical leg.

We can find this by using pythagoras theorem.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides

52.5²=42.7²+x²

2756.25=1823.29+x²

Subtract 1823.29 on both sides

2756.25-1823.29=x²

932.96=x²

Taking square root on both sides

x=30.54

Hence, the length of the vertical leg is 30.54cm.

In mathematics, a ratio shows how frequently one number appears in another.

For instance, the ratio of oranges to lemons in a fruit plate would be eight to six if there were eight oranges and six lemons.

Oranges make up 8:14 of the total fruit, whereas lemons make up 6:8 of the total fruit.

So, 1st we have a rectangle which:

width 14cm

Just get the ratio of length:width:

When height becomes 1cm, then according to the ratio the width will be:

1/2 * 1/1 = 1/2cm

We have to find how many license plates have at least a repeated letter.

For this,

We will first find how many different license plates the country can produce and how many license plates have no repeated letter.

The country can produce:

10 x 26 x 26 x 26 x 26 x 26 = X

10 x 11,881,376 = X

b) The subtotal of a person with a sales tax of $1.61 is of: $16.95.

The amounts are obtained applying the proportion of 9.5%, which represents the sales tax of this restaurant.

The sales tax of the person with a subtotal of $24.95 is obtained with the multiplication of the subtotal by the sales tax of 9.5% = 0.095 as follows, hence:

Sales tax = 0.095 x 24.95 = $2.37.

The subtotal of a person with a sales tax of $1.61 is obtained considering that $1.61 represents 9.5% = 0.095 of the subtotal x, due to the tax rate, as follows:

0.095x = 1.61

x = 1.61/0.095

Answer And step-by-step explanation: The sum of x and y is 58. In other words, x plus y equals 58 and can be written as equation A:

x + y = 58

The difference between x and y is 18. In other words, x minus y equals 18 and can be written as equation B:

x - y = 18

Now solve equation B for x to get the revised equation B:

x - y = 18

x = 18 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 58

18 + y + y = 58

18 + 2y = 58

2y = 40

y = 20

Now we know y is 20. Which means that we can substitute y for 20 in equation A and solve for x:

x + y = 58

x + 20 = 58

X = 38

Step-by-step explanation:

We can create a right triangle with the following points:

- the top of the lighthouse

- the base of the lighthouse

- the rock jutting out of the water

I will label the distance from the base of the lighthouse to the rock d.

See the attached image for a detailed model.

Then, solve for the two acute angles of the triangle.

The larger acute angle (∠1) is complementary to 6°, so we can solve by setting their sum to 90°:

6° + m∠1 = 90°

m∠1 = 84°

Because this is a right triangle, the smaller acute angle (∠2) is complementary to the larger acute angle, so we can solve once again by setting their sum to 90°:

m∠1 + m∠2 = 90°

84° + m∠2 = 90°

m∠2 = 6°

We can use either of these angles in combination with the trigonometric ratio tangent to solve for the distance d. I will use tangent of ∠1.

[tex]\tan(84\textdegree) = \dfrac{d}{85 \, \textrm{ft}}[/tex]

[tex]d = 85\tan(84\textdegree)[/tex]

[tex]d \approx 808.72 \, \textrm{ft}[/tex]

Step-by-step explanation:

The values will be of two digit either 92 or 29, 74 or 47 etc.

Let M = AB(A..B = 0…9) and N = BA. where A and B are numbers from 0 to 9.

The subtraction rule requires the last digit of the difference to be the Difference of A-B. To explain further, for example 44, take the last digit 4. This can be expressed as the difference of 5-1, 8-4, 4-0. (meaning 1st digit is A and 2nd digit is B) = 88 - 44 = 44, similarly 99-55  = 44, 44-0 = 44. So we can represent 44 according to the rules above.

For numbers greater than 100, the last digit can be represented as the sum of the numbers 0 through 9 and the numbers greater than 5. To explain this, let's analyze 121. The last digit is 1.

digit can be represented as the sum of the numbers 0 through 9 and the numbers greater than 5. To explain this, let's analyze 121.

The last digit is 1. Since the number is greater than 100, it must be expressed as the sum of single digit numbers that sum to 11,

so 9+2.8+3.7. + 4.6+5, then applying any of these gives 92+29 = 121, 83+38 = 121, 74+47+121, 65+56=121. So 121 is removed.

Quadratic formula is used to find the roots of a quadratic function f(x) = ax² + bx + c as x = (-b ± √(b² - 4ac))/2a.

The expression b² - 4ac is called the determinant D.

When D = 0, roots are real and equal.

For D > 0, roots are real and unequal and for D < 0, roots are complex conjugates.

The given quadratic function is f(x) = 2x² + 7x - 4.

The cost function is C(w) = 300/w + 18w² and the cost of materials for the cheapest such container is $222.0

From the question, we have the following parameters that can be used in our computation:

The length is twice the width;

Volume = 10m³

This means that:

V = 10

l = 2w

The volume of the container is calculated as:

V = lwh

So, we have

v = 2w²h

By substitution, we have

h = v/2w²

So, we have

h = 10/2w²

Divide

h = 5/w²

The surface area of an open rectangular storage is:

A = 2h(l + w) + lw

So, we have

A = 2h(2w + w) + 2w²

A = 2h(3w) + 2w²

Substitute h = 5/w²

A = 2 * 5/w² * (3w) + 2w²

Evaluate

A = 20/w + 2w²

The base costs $15, and the sides cost $9

So, the cost function is:

C(w) = 15 * 20/w + 2w² * 9

Rewrite as:

C(w) = 300/w + 18w²

We have

C(w) = 300/w + 18w²

Differentiate

C'(w) = -300/w² + 36w

Set to 0

-300/w² + 36w = 0

Rewrite as:

-36w = -300/w²

Cancel out the negatives

36w = 300/w²

Multiply through by ²

36w³ = 300

Divide through by 36

w³ = 8.33

Take cube roots of both sides

w = 2.03

Recall that:

C(w) = 300/w + 18w²

So, we have:

C(2.03) = 300/2.03 + 18(2.03)²

Evaluate

C(2.03) = 222.0

Hence, the cost of the materials is $222.0
