After 4 new students joined a class, the class had 32 students. Which equation can be used to find n, the number in the class be

Vadim26 [7]

Answer:

n+4=32

Step-by-step explanation:

The initial number n gets additional 4 students making the new total number of students to be 32. Therefore, this situation can be represented as

n+4=32

To get the actual number of students before the additio, we make n the subject of formula hence

n=32-4

n=28

Therefore, the initial number was 28 and the equation is n+4=32

Since no choices were provided, the equation that can be modified is n+4=32

Solve for b: 16b = 12

Zina [86]

Answer:

b = 3/4

Step-by-step explanation:

Hi!!!

You want the value of B. To get that, we have to divide both sides by 16:

$\frac{16}{16}b =\frac{12}{16}$

$\frac{12}{16} = \frac{3}{4}$

Thus the answer to your question is $$\boxed{b = \frac{3}{4} }$ .

<u>Check:</u>

3/4 * 16 = 3 * 4 = 12.

12 = 12

So we are correct!!!

The area of the curved surface of a cylindrical can is 162 π square centimeters and it’s height is 9 centimeters. What is the di

asambeis [7]

Answer:

Diameter of the can = 18 Cm

Step-by-step explanation:

Given:

Curved surface of cylindrical can = 162 $\pi$

Height of cylindrical can = 9 Cm

Find:

Diameter of the can = ?

Computation:

Curved surface of cylindrical can = 2 $\pi$ rh

$162\pi = 2\pi rh\\\\\frac{162\pi }{2\pi }= r\times 9\\\\81 = r\times 9\\\\\frac{81}{9}=r$

$r=9 Cm$

Diameter of the can = 2×r

Diameter of the can = 2×9 Cm

Diameter of the can = 18 Cm

Simplify the expression.

bearhunter [10]

Answer:

D. x to the power of nine

Step-by-step explanation:

The applicable rule of exponents is ...

(x^a)^b = x^(ab)

You have a=3/2, b=6, so ab = 3/2·6 = 9.

(x^(3/2))^6 = x^(3/2·6) = x^9
