What is 1/3 of 77 how did you do it

Answers

Answer:

25.67

Step-by-step explanation:

One third written as a fraction is 1/3. You can also write it as a decimal by simply dividing 1 by 3 which is 0.33.

If you multiply 0.33 with 77 you will see that you will end up with the same answer as above.

You may also find it useful to know that if you multiply 0.33 with 100 you get 33.33. Which means that our answer of 25.67 is 33.33 percent of 77.

mr dela cruz uses 18 yards of cloth for making 5 pants how many pants will he make for 72 yards of cloth​

Answers

Answer:

18÷5= 3.6

3.6 = 4 yards

72 yards of cloth ÷ 4 yards of cloth = 18 pants

Step-by-step explanation:

3.6 yards rounded to the nearest is 4. So it takes 4 yards of cloth to make 1 pants. Since it takes 4 yards of cloth to make 1 pants, we simply divide 4 yards into 72 yards which equals to 18 pants.

6) The third side must be more than 3 and less than 13.

Step-by-step explanation:

The third side must be more than the difference and less than the sum of the two numbers.

5) 9-5=4

9+5=14

So the third side must be more than 4 and less than 14.

6) 8-5=3

8+5=13

So the third side must be more than 3 and less than 13.

Roy weighs 120 pounds and plans to gain 2.5 pounds a week. Luis weighs 1 point
220 pounds and plans to lose 3.5 pounds a week. Which equation shows
when Roy and Luis will weigh the same?

Answers

The equation 120+2.5x=220-3.5x

Answer:

2.5x + 120 = -3.5x +220; after about 16.6 weeks Roy and Luis will weigh the same amount in pounds

Step-by-step explanation:

Roy's: y = 2.5x + 120

Luis': y = -3.5x + 220

x is representing the number of weeks and y is representing the total number of pounds each will weight after x weeks.

1) set the two equations equal to each other because you want them to weigh the same amount (this might be your equation if they don't want you to solve for the number of weeks)

2.5x + 120 = -3.5x +220

2) Solve for x to find after how many weeks they will weigh the same

2.5x = -3.5x +100

6x = 100

x = 16.6667 weeks
