Answer:

Step-by-step explanation:

15 = 1*3*5

64 = 1*8*8 = 1*2*2*2*2*2*2

15 and 64 have only "1" that presents in both 15 and 64.

So, GCF of 15 and 64 is 1.

A classroom globe has a diameter of 12 inches. What is the volume of the globe? Use 3.14 for pi. Round your answer to the nearest hundredth. 904.32 in3

7238.23 in3

9202.77 in3

Answers

V= $(4)/(3) \pi r^(3)$

r=12/2=6
pi=3.14

V= $(4)/(3)(3.14)*(6)^(3)$

V= $(4)/(3)(3.14)*216$ =904.32 $in^(3)$

The answer is 904.32 $in^(3)$ . Sorry. I used the wrong formula. ^^;

The answer would be 904.32

Answers

the answer is 8/10 16 divided by 2 and 20 divided by 2

16/20 = 8(2)/10(2) = 8/10. 8/10 can also be further reduced to 4/5.

Which expressions are equal to a real number?

Answers

Answer:

Option B

Option C

Step-by-step explanation:

$i = √(-1)$

⇒ $i^2 = (√(-1))^2 = -1$ , which is a real number.

Similarly, $i^3 = i^2.i = -1 * i = -i$

And we also know that $i^4 = 1$

So, we see that odd powers of $i$ is a complex number and even powers renders us a real number.

Using this we solve the problem.

Option A: $(-4i)^(11)$ 11 is an odd power. This would be a complex number and not a real number.

Option B: $(-3i)^(12)$ Even power of i. So, this should give us a real number.

Option C: $(2 + 3i)^2$

(a + bi)² = a² - b² + 2abi

So, (2 + 3i)² would be a complex number because of the 2bi term.

Option D: (4 + 5i)(4 - 5i)

(a + ib)(a - ib) = a² + b²

So, (4 + 5i)(4 - 5i) = 4² + 5² = 41, a real number.

Option E: (6 + 8i)(8 + 6i)

(a + ib)(c + id) = ac - bd + (ad + bc)i

This would be a complex number because of the (ad + bc) term.

So, Options B and D are real numbers.

i got a A ON the test

At a restaurant after every 12th visit you receive a free drink. After every 15th visit you receive a free dessert. At which visit will you first receive a free dessert and a free beverage?

Answers

On the 60th visit, you will get both free dessert and a free beverage.

What is the pattern?

A pattern is a specific arrangement of numbers or any term which will follow a specific code or hint.

The hint which is present in a given pattern hides in the pattern only.

For example 2,4,6,8 in this, the difference between any two-term is only 2 and this will be its specific pattern.

Another example is 2,4,16,256 in this pattern each term is the square of the previous term and this will become its specific pattern.

Given,

At every 12th visit, we get a beverage

At every 15th visit, we get dessert

So let's say at x visit we get both

So,

x should be a minimum result of multiple of both 12 and 15

So,

12 (5) = 60 and 15(4) = 60

So 60 is the minimum result.

Hence, On the 60th visit, you will get both free dessert and a free beverage.
