Answer:

x=3

Step-by-step explanation:

Since they are similar triangles, we can use ratios to solve

x 3.5

----- = -------

6 7

Using cross products

7x = 21

Divide each side by 7

7x/7 = 21/7

x = 3

This question is worth 50 points, make sure to provide ALL calculations without using a calculator, though.

Answer:

Step-by-step explanation:

Use the formula for the volume of a cone:

V = (1/3)(area of base / round opening)(height of cone)

In this case we're interested in the following:

(1/3)(area of base / round opening)(height of cone) ≤ 535 cm³

First, mult. both sides by 3 to elim. the fraction 1/3:

(area of base)(height) ≤ 1605 cm³

Since the height is 8 cm, we now have:

(area of base) / (8 cm) = 1605 cm³, or

(area of base) = (1605 cm³) · (8 cm) = 200.625 cm²

The formula for the area of a circle is A = 3.14·r², where r is the radius.

If the area of the base is 200.625 cm², as found above, this equals 3.14r², and so

r² = (200.625 cm²) / (3.14) = 63.89 cm²

Then the radius must be +√63.89 cm, or 8 cm

and the diameter must be 2r = 2(8 cm) = 16 cm. This would be the largest width of the container.

Match each function with the expression representing its inverse function.

Georgia [21]

Answer:

A matches with 5.
B matches with 3.
C matches with 2.
D matches with 6.
E matches with 4.
F matches with 1.

Step-by-step explanation:

To find the inverse of a function $f(x)$ , we let $f(y)=x$ and then solve again for y.

For example, using $g(x)=-0.5x$ , we will let $g(y)=x$ , giving $x=-0.5y$ . This means that $y=-2x$ , and thus $g^{-1}(x)=-2x$ .

Using similar logic, we see that:

A matches with 5.
B matches with 3.
C matches with 2.
D matches with 6.
E matches with 4.
F matches with 1.

Dominic is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The monthly fe

insens350 [35]

The equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t

<h3>Equation</h3>

There are three basic types of equation in mathematics. Namely:

Linear equations
Quadratic equations
Simultaneous equations

Monthly fee = $50
One-time joining fee = $150
Total cost = C
Number of months = t

C = 150 + 50t

Therefore, the equation for C in terms of t,t, representing the total cost of the gym membership over tt months is C = 150 + 50t
