What ratio is equivilant to 4:13 which makes 85?

Answers

Answer 1

Answer: Let us assume the common ratio to be = x
then
4x + 13x = 85
17x = 85
x = 85/17
= 5
Then
The ratio will be = 4 * 5:13 * 5
= 20:65
So the ration in which the number 85 can be separated is 20:65. i hope the procedure is clear enough for you to understand. You can always use this method for solving similar problems without taking any help from outside. Only be careful while calculating.

tyler mixed 1 1/2 cups of flour with 3/4 cup of sugar. What is the total amount of flour and sugar tyler mixed?

Answers

Hello! try simplifying those two numbers so that they have the same denominators. You can see that you can convert 11/2 of flour so that you can add it with 3/4 of sugar and get the total amount together.

To convert multiply the top and bottom by 2 $(11)/(2) &* (2)/(2) = (22)/(4)$ :

Now add across the top numbers $(3)/(4) + (22)/(4) = (25)/(4)$ :

And finally simplify the fraction to get your final answer. You can pull out 24 out of 25 as the common factor for 4 and 6 $(25)/(4)=6 (1)/(4)$ and the remainder will be in the numerator.

In a certain math class, it is known that 18 students LOVE math review, and 5 students dislike math review. The teacher randomly selects three students from the class. What is the probability that all three students love math review?

Answers

The probability that the first random choice will be a matho-file and not a -phobe is 18/23. The probability of the second one is 17/22, and for the third one it's 16/21. The probability of all 3 is 4,896/10,626 = (18x17x16)/(23x22x21). That's 46.1% (rounded).

Timers at a swim meet used four different clocks to time an event. Which recorded time is the least precise?a. 48.9107 s
b. 48.91 s
c. 48.910 s
d. 48.9 s

Answers

Answer:

The time recorded as 48.9 s (option: d) is least precised as compared to other times.

Step-by-step explanation:

" Precision refers to the closeness of two or more measurements to each other" .

Since, in options a,b and c the time represented is quite close as they are precised to two or more decimal places.

but in option 'd' the time is precised to just one decimal place.

Hence, the time recorded as 48.9 s is least precised.

Hence, option D is the correct answer.

d. It's precise to only one decimal place
