Answer:

D. 54%

Step-by-step explanation:

Find the relative frequency of it landing on heads by dividing 27 by 50, then multiplying it by 100

27/50

= 0.54

0.54(100)

= 54

So, the relative frequency is 54%

The correct answer is D. 54%

Answer:

x=20

Step-by-step explanation:

It all equals 360º and there are two of each angle. So, we can add 5x+5x+(3x+20)+(3x+20)=360º. Subtracted 40 and simplify. So 16x=320.So divide by 16 and you get that x=20.

The ratio of hydrogen to oxygen atoms in water molecules is 2 to 1. If the beaker of water contained 4.1 moles of oxygen atoms,
Ad libitum [116K]

Answer:

8.2

Step-by-step explanation:    

We have been given that the ratio of hydrogen to oxygen atoms in water molecules is 2 to 1.      

We can represent this information as: \frac{\text{Hydrogen}}{\text{Oxygen}} =\frac{2}{1}

Let x be amount of moles of hydrogen atoms in water beaker. The proportion of hydrogen and oxygen moles will be same in water beaker.

Upon substituting our values in above proportion we will get,

\frac{2}{1} =\frac{x}{4.1}            

x=2\times 4.1              

x=8.2    

Therefore, the moles of hydrogen atoms in water beaker will be 8.2.

You are buying fruit to make fruit baskets apples come in bags of 20. Ornages come in bags of 16. And bananas come in bags of 32
QveST [7]

Answer:

160 basket of each fruit baskets we can make using all fruit.

Step-by-step explanation:

Given:

Oranges comes in bags = 16

Apples comes in bags = 20

bananas come in bags = 32

We need to find the greatest number of fruit baskets that you can make using all fruit.

Also Given:

You have one bag of each fruit basket must be identical.

So we will first find the least common multiple of all the numbers we get;

20 = 20,40,60,80,100,120,140,160

16 = 16,32,48,64,80,96,112,128,144,160

32 = 32,64,96,128,160

The least common multiple is 160.

Hence we can say that, 160 basket of each fruit baskets we can make using all fruit.
