The ratio 20/10=5/n. What does n equal?

Answers

Answer 1

Answer: n is equal to 2.5

I divided 20 by 5 to get 4. = 20 ÷ 5 = 4. So, I divide 10 by 4 to get n. = 10 ÷ 4 = 2.5

Or we can do this solution.

20 5
---- = ---- ; do cross multiplication. 20n = 10(5)
10 n

20n = 50 ; to get n, divide both sides by 20. 20n / 20 = 50 / 20 = n = 2.50

Whichever way: 20/10 = 5/2.5

Which interval for the graphed function contains the local maximum? A ( -3,-2)
B (-2,0)
C (0,2)
D (2,4)

Answers

Answer:

Option C is correct .i.e., ( 0 , 2 )

Step-by-step explanation:

We are given with a graph.

To find: Interval of local maximum

We can clearly see from graph that there is only one point of maximum.

Point of maximum is ( 1.55 , 10.8 )

Option A:

Interval is ( -3 , -2 ) means x > -3 & x < -2

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Option B:

Interval is ( -2 , 0 ) means x > -2 & x < 0

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Option C:

Interval is ( 0 , 2 ) means x > 0 & x < 2

Here, this interval contain x-coordinate of point of Maximum.

Thus, this option is correct

Option D:

Interval is ( 2 , 4 ) means x > 2 & x < 4

but this interval does not contain x-coordinate of point of Maximum.

Thus, this option is incorrect

Therefore, Option C is correct.

What is a 33.33% increase followed by a 50% decrease?

Answers

33.33-50=-16.67%
hope that helped :)

If you let x = the original amount, then an increase of 33.33% would be represented by

x + (x × 33.33%)

Then if there was a decrease of 50%, you would now have

[x + (x ×33.33%)] × 50%

rewrite with decimal instead of %

[x + (x × .3333)] ÷ 2

The brackets and parentheses are important to tell the order in which to proceed.

1.A pizza place offers 6 different cheeses and 12 different toppings. In how many ways can a pizza be made with 1 cheese and 3 toppings?2.How many ways can you purchase 5 CDs if there are 6 to choose from, 2 cassettes if there are 5 to choose from, and 4 DVDs if there are 8 to choose from?

Answers

1.) You have 12 toppings. You choose one topping--that leaves you with 11 toppings. You choose another--that leaves 10. 12×11×10 = 1,320.
Multiply 1,320 topping choices by 6 cheeses to get 7,920 total combinations.

2.) (Though I'm less sure of these)
CDs: 6×5×4×3×2 = 720
Cassettes: 5×4 = 20
DVDs: 8×7×6×5 = 1680
