Answer:

The annual total cost is $135 when he purchases 17 books

Step-by-step explanation:

Given function is:

C(b) = 5b + 50

Here c is the output which is cost and b is the input which is number of books purchased in an year.

In order to find the total cost when he purchases 17 books, we have to put 17 in place of b and find the cost.

So,

Putting b = 17

[tex]C(17) = 5(17) + 50\\= 85+50 = 135[/tex]

Hence,

The annual total cost is $135 when he purchases 17 books

Answer:

1.25x

Step-by-step explanation:

Given that :

25% Increase in number of blog views can be expressed as (x + 0.25x)

Another way to make this representation is :

Total number of blog views + 25% of total

Total should add up to 100%

Let number of views = x

Hence,

(100% + 25%) of x

125% of x

125%x

= 1.25x

Answer:

Option B

Step-by-step explanation:

Slope = Change in y / Change in x

Slope = (8 - 2) / {6 - (-4)}

Slope = 6 / (6 + 4)

Slope = 6 / 10

Slope = 3 / 5

So option B is your answer

Answer:

30

Step-by-step explanation:

since x=5, and it's 6x, it'd be the same as 5x6, or 6(5).

Answer:

I think it should equal 30

Step-by-step explanation:

If x is 5 it would be 6(5) so you multiply 6 and 5 which equals 30

Step-by-step explanation:

Answer:

60/1 or 60

Step-by-step explanation:

Divide 180 by 3

60

So the unit rate is 60/1

Answer:

60 miles per hour

Step-by-step explanation:

The unit rate is the number of miles traveled per hour.  To solve this divide the total miles traveled by number of hours, 180/3.  The quotient is 60.

Answer:

well you do 1 divided by 2 which is 0.5

Answer:

0.2839

Step-by-step explanation:

Can you tell me what part you are stuck on?

Answer:

0.2839

Step-by-step explanation:

-First, move the decimal over 4 places to the right to make 0.0167 into a whole number, which will turn into 167.

-Now, multiply 17 times 167 to get 2839.

-Finally, since the decimal from 0.0167 was moved 4 places to the right, it needs to be moved back 4 places to the left. Once it was moved back 4 places to the left, the answer should now be 0.2839

Hope this helps! :)

Answer:

8. 9.1

9. 12.2

Step-by-step explanation:

8. let x represent the missing side:

Using pythagoras theorem;

13.3² = x² + 9.7²

x² = 13.3² - 9.7²

x² = 82.8 taking the square root of both sides;

x = 9.1

9. let y represent the missing side:

Using pythagoras theorem;

y² = 10² + 7²

y² = 149 taking the square root of both sides;

y = 12.2

Answer:

5 hot dogs packs at least and 4 buns packs at least

Step-by-step explanation:

Answer:

The two number are :

x = 1411

y = 1079

Step-by-step explanation:

Let the two numbers = x and y

The sum of two numbers is 2490

x + y = 2490..... Equation 1

If 6.5 percent of one no. is equal to 8.5 percent of the other,

Hence:

6.5% of x = 8.5% of y

0.065x = 0.085y

Make x the subject of the Formula

x = 0.085y/0.065

x = 1.308y

We substitute 1.308y for x Equation 1

x + y = 2490..... Equation 1

1.308y + y = 2490

2.308y = 2490

y = 2490/2.308

y = 1078.8561525

y = 1079

x + y = 2490..... Equation 1

x = 2490 - y

x = 2490 - 1079

x = 1411

Answer:

Answer:640^2

Step-by-step explanation:

The Pythagorean Theorem states that the sum of the squared sides of a right triangle equals the length of the hypotenuse squared. You might recognize this theorem in the form of the Pythagorean equation: a 2 + b 2 = c 2.

8cm^2+24cm^2=640^2

Answer:

∠2 and ∠5 should not be Alternate exterior angles. ∠2 and ∠11 can be Alternate exterior angles if that is an option. The rest is correct. As for consecutive interior angles, you have (∠3 and ∠9), (∠4 and ∠10), (∠7 and ∠13) and (∠8 and ∠14).

Step-by-step explanation:

Alternate exterior angles are basically like the angles that are the combination of a vertically opposite angle and a corresponding angle. Since the vertical lines are not parallel, ∠2 and ∠5 cannot be Alternate exterior angles.

Consecutive interior angles are any pair of angles that are within a pair of parallel lines and add up to 180°.

Answer:

The value if x is 20

Step-by-step explanation:

Hope this helps :)

The value of the variable x is 20. Then the correct option is A.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

If the two chords of the circle intersect at a point, then the product of the segments of the chord will be equal.

We know that the product of (x - 5) & (x - 8) and (x - 5) & (x) will be equal. Then we have

(x - 5) · (x - 8) = (x - 11) · x

Simplify the equation, then the value of the  variable x will be

(x - 5) · (x - 8) = (x - 11) · x

x² - 13x + 40 = x² - 11x

2x = 40

x = 20

Thus, the value of the variable x is 20.

Then the correct option is A.
