\displaystyle \frac{7a}{9bc}  \div\frac{21a}{12b} =\frac{\backslash\!\!\!\!7a}{9 \backslash \!\!\!b \ c} \cdot \frac{4\backslash\!\!\!b}{\backslash\!\!\!\!7a} =\boxed{\frac{4}{9c} }

<h3>Answer:   7 goes in the blank space</h3>

The range of values for x is 2 < x < 7

========================================

Explanation:

The hinge theorem says that the larger the opposite side is, the larger the angle will be.

AD = 11, DC = 8

Since AD > DC, this means angle ABD > angle DBC.

--------

angle ABD > angle DBC

20 > 4x-8

20+8 > 4x-8+8 ... add 8 to both sides

28 > 4x

4x < 28 ... flip both sides and the inequality sign

4x/4 < 28/4 ... divide both sides by 4

x < 7

--------

At the same time, the angle 4x-8 cannot be 0 or negative.

So we say 4x-8 > 0. Let's solve this for x.

4x-8 > 0

4x-8+8 > 0+8 ... add 8 to both sides

4x > 8

4x/4 > 8/4 ... divide both sides by 4

x > 2

2 < x ... flip both sides and the inequality sign

--------

We have 2 < x and x < 7. Both of these combine to the compound inequality 2 < x < 7

We can pick any value between 2 and 7 as long as we dont pick x = 2 or we dont pick x = 7.

Jesse is looking for the volume of the cone below, and she is using the formula V=(1/3)Bh. Which of the following is the value o
Sidana [21]

Answer:

B =  \pi *r^2

(Base of the cone)

Step-by-step explanation:

The volume of the cone is always 1/3 of the volume of a cylinder with the same radius and height.

Volume of the cylinder

V_cylin = ( \pi *r^2 )* h

Where

r is the radius

h is the height

This means the volume of the cone is equal to

V_cone = (1/3)* ( \pi *r^2 )* h

By looking to the equation of the problem

V=(1/3)Bh

We can easily deduce that

B =  \pi *r^2

(Base of the cone)

The ABC Book club charges a $40 monthly fee, plus $2 per book read in that month. The Easy Book Club charges a $35 monthly fee,
alina1380 [7]

Answer:

5 books must be read in 1 month for the total charges from each club to be equal.

Step-by-step explanation:

Monthly Charges of ABC club = 40$

Per book read charges of ABC club = 2$

amount of book read = x

Total charges of ABC club = 40 + 2x

Monthly Charges of Easy book club = 40$

Per book read charges of Easy Book club = 3$

Total charges of Easy book club = 35 + 3x

To calculate how many books must be read in 1 month for the total charges from each club to be equal,

Total charges of ABC club =  Total charges of Easy book club

40 + 2x = 35 + 3x

40 - 35 = 3x -2x

5 = x

x = 5

Therefore, 5 books must be read in 1 month for the total charges from each club to be equal.
