Sammy had 30 minutes to do a three problem quiz. She spent 101/3 minutes on problem 1 and 54/5 minutes on problem 2. How much time did she have time for problem 3? Write your answer as a mixed number.

Answers

He is left with $13(13)/(15)$ minutes for the last problem

Step-by-step explanation:

Given

Total time = 30 minutes

Time spent on problem 1: $10(1)/(3)$ minutes

Time spent on problem 2: $5(4)/(5)$ minutes

First of all, we will calculate the total time for 2 problems

$Time\ for\ two\ problems = 10(1)/(3)+5(4)/(5)\n= (31)/(3) + (29)/(5)\n= (155+87)/(15)\n=(242)/(15)$

The remaining time is:

$Time\ for\ problem\ 3 = Total\ time - Time\ for\ two\ problems\n= 30 - (242)/(15)\n= (450-242)/(15)\n=(208)/(15)\n= 13(13)/(15)$

Hence,

He is left with $13(13)/(15)$ minutes for the last problem

Stacy wants to make 100 name tags with ribbons ATTACHED TO THEM. each name tag requires 5 centimeter of ribbon. SHE HAS 3.25 meters of ribbon. exactly how many more centimeters of ribbon does stacy still need to make 100 name tags

Answers

Each meter has 100 centimeters. With just 1 meter, you can make 20 name tags with ribbons. So in order to make all of the name tags, you need 5 meters. 5 - 3.25 = 1.75. You need 1.75 more meters of ribbon to make all 100 of the name tags with ribbons.

What does 2/3 x 2 equal! Someone please help as soon as possible!

Answers

The first step we have to do is: 2/3 × 2. If it is multiplying a whole number to a fraction, multiply the whole number by the numerator. In this case, the numerator is 2, so we can do: 2 × 2 to get 4.

From multiplying, our new fraction would look like: 4/3. You can keep it as an improper fraction or you can turn it into a mixed fraction. To do so, divide the numerator by the denominator (4 ÷ 3) to get the answer of 1.3333, Keep the original denominator, write the remainder as the numerator, and whatever whole number you get, goes in front of the fraction. Since 4 ÷ 3 = 1 with a remainder of 1, we can keep the denominator, and switch out the numerator with 1, and also the whole number.

The answer as an improper fraction: 4/3
The answer as a mixed fraction: 1 1/3
The answer as a decimal: 1.3333
