Alex opens a 1-pint container of orange butter. He spreads 1/16of the butter on his bread. The he divides the rest of the butter into 3/4-pint containers.how many 3/4-pint containers is he able to fill?

Answers

The first thing to do is to make the denominators of the fractions the same: 
16 / 4 = 4.  4 X 3 = 12. 
12/16. 

16 / 1 = 16.  16 X 1 = 16
16/16

Now you write this out as a fraction equation: 
(16/16 - 1/16) / 12/16
15/16 / 12/16

Since all you need to know is the whole number, you can easily tell that 15 / 12 is less than 2.  

Therefore, Alex is able to fill one 3/4-point containers with orange butter. 
One pint can fill only a single 3/4-pint container, even before anybody takes away any of the full pint.

Find the slope of the line that passes through the points (–2, 2) and (13, –7).A. -1.67
B. -0.6
C. 0.6
D. 1.67

Answers

The slope of the line should be -0.6.

Given that,

  • The points are (–2, 2) and (13, –7).

Based on the above information, the calculation is as follows:

= (y_2 - y_1) / (x_2- x_1)\n\n= (-7 -2) / (13 + 2)\n\n= -9 / 15

= -0.6

Ken spends 1/5 of his money on a dictionary. He gives $21 to his brother and has1/2 of his money left. How much money does Ken have left?

Answers

Ken has 1 of his money. He spends 1/5 so he still has 4/5 of the original amount of money. He has 4/5 and he spends $21and ends up with 1/2 of his money. 4/5 = 8/10 and 1/2 = 5/10.This means that $21 is 8/10-5/10 of his original amount of money. so $21 is 3/10 of his original amount of money. 21/3*10=70. His original amount of money is $70. This means that 1/2 of his money is $35. So Ken has $35 left.

Answer:

Ken has 1 of his money. He spends 1/5 so he still has 4/5 of the original amount of money. He has 4/5 and he spends $21and ends up with 1/2 of his money. 4/5 = 8/10 and 1/2 = 5/10.This means that $21 is 8/10-5/10 of his original amount of money. so $21 is 3/10 of his original amount of money. 21/3*10=70. His original amount of money is $70. This means that 1/2 of his money is $35. So Ken has $35 left.
