A large university accepts 60​% of the students who apply. Of the students the university​ accepts, 40​% actually enroll. If 30,
kykrilka [37]

Answer:

7,200

Step-by-step explanation:

Let's start by calculating how many students the university accepts. The problem says they accept 60% of the students. 60% as a decimal is 0.6. To calculate 60% of something, you multiply .60 by whatever quantity. In this case, it would be the students.

Number of accepted students = .6 * 30000 = 18,000

The university accepts 18,000 students.

Now, the next problem is that of those accepted students, we need to find out how many actually enroll. The problem says they accept 40% of the accepted students. Applying the same principle,

Number of enrolled students = .4 * 18000 = 7,200

The number of students that actually enroll is 7,200.

Alternatively, .6 * 30000 * .4 would give you the same result.

Combining the pieces together, we are asking for 60% of 30,000. Then getting 40% of that 60%.

Find the surface area of a sphere with a diameter 10 cm.
solong [7]

Answer:

c.

314 sq. cm

Step-by-step explanation:

Surface area of sphere:

The surface area of an sphere with radius r is given by:

S = 4\pi r^2

Find the surface area of a sphere with a diameter 10 cm.

Radius is half the diameter, so r = \frac{10}{2} = 5

The surface area is:

S = 4\pi*5^2 = 100\pi = 314

314 square centimeters, and option c is the answer.

What is the value of 10x^3 y^2 when x=-2 and y=-3
Sholpan [36]

Answer:

-720

Step-by-step explanation:

We are given the expression:

10x^3y^2

and asked to evaluate when x= -2 and y= -3.

Therefore, we must substitute -2 for x and -3 for y.

10(-2)^3*(-3)^2

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Evaluate the first exponent.

⇒ (-2)³ = -2 * -2 * -2= 4*-2= -8

10(-8)*(-3)^2

Evaluate the second exponent.

⇒ (-3)²= -3 * -3= 9

10(-8)*9

Multiply 10 and -8.

-80*9

Multiply -80 and 9.

-720

The value of 10x³y² at x= -2 and y= -3 is -720
