Find the following:
9 11/60 − 3 13/80
Answers
Answer: 6 1/48
Answer:
Step-by-step explanation:
Let reformat the problem. :)
\(9\frac{11}{60} -3\frac{13}{80}\)
Then we turn the equation in improper fractions.
\(\frac{551}{60} -\frac{253}{80}\)
Then we need to have common denominators
Which is 240.
After solving, we get the answer \(\frac{1445}{24}\)

A photo of a beetle in a science book is increased to 778% as large as the actual size. If the beetle is 15 mm, what is the size of the beetle in the photo
Answers
Answer:
Step-by-step explanation:
If the beetle is 15 mm in actual size, and the photo is increased to 778% of the actual size, then we can find the size of the beetle in the photo by multiplying its actual size by 7.78:
Size of beetle in photo = Actual size of beetle x 7.78
Substituting the given value of the actual size, we get:
Size of beetle in photo = 15 mm x 7.78
= 116.7 mm
Therefore, the size of the beetle in the photo is 116.7 mm.

Is 4/5 divided by 1/3 greater than 1
Answers
Answer:
Yes
Step-by-step explanation:
It's 12/5 or also 2.4
Answer:
yes
Step-by-step explanation:
remember how to do fraction operations :
a/b / c/d = a×d / b×c
that is why you can also say it is the same as the multiplication with the upside-down fraction
a/b / c/d = a/b × d/c = a×d / b×c
in your case here
4/5 / 1/3 = 4/5 × 3/1 = 12/5
and that is definitely greater than 1.
A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18
Round 18.049 to the nearest tenth.
Answers
Answer:
18.0
Step-by-step explanation:
Note the tenth place value (underlined and bolded): 18.049
Look at the number to the direct right of the tenth place value (or the hundredth place value in this case). It is a 4.
Note the rules of rounding. If the number:
1) is 5 or greater, round up.
2) is 4 or less, round down.
In this case, it is 4, so you will round down.
18.049 rounded to the nearest tenth is 18.0

Which is the more reasonable measurement of the distance between the tracks on a DVD: 7.4 ⋅ 10−4 mm or 7.4 ⋅ 104 mm? Justify your answer.
Answers
Answer:
A- 7.4 ⋅ 10−4 mm
Step-by-step explanation:
Well, to solve this problem, we must convert the number and / or the units in a more imaginable one.
We are given two choices:
a. 7.4 x 10^-4 mm
b. 7.4 x 10^4 mm
Converting the units and numbers into meters and general form, respectively. (What is meant by general form is not to write it in scientific notation).
a. 7.4 x 10^-4 mm (1 m / 1000 mm) = 0.00000074 m
b. 7.4 x 10^4 mm (1 m / 1000 mm) = 74 m
Now comparing the two values above, what do you think is the distance between the tracks on a DVD? Definitely NOT 74 m or else the DVD is extremely big. Therefore the correct is the smaller one.

set as a fraction:
Numerator = amount needed (2)
Denominator = all things/objects involved (10)

With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction
ex:
10/2=5=500% (this can't be the answer)
So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

To find the x intercepts you must put y=0; in this way you fix at zero the coordinate y of the points you are seeking. You are left with finding the coordinate x of the points. If y=0 you are left with: 0=ax2+bx+c which is a second degree equation.

Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666...

explain how the models in questions 4 and 5 are the same

Answer:
Hi!
So, for question 4, when you divide it by two, you can split it horizontally to make it 6 squares instead of 3 rectangles from the model of the 1/3, leaving 2 shaded squares and 4 unshaded squares. And since you're dividing it by 2, you only use 1 of the shaded squares.
For question 5, I made the one-half horizontal instead of vertical so you can easily overlap the 2 models when you multiply them. Similar to question 4, the model becomes 6 squares and the 2 models overlap on one square.
Hope this helps! :)

Also, just post one question at a time. We aren't allowed to post multiple answers.
Five people can be in a group. There's 12 people. The combination will be 792 groups
What is the combination?Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.
The number of r-element combinations of n objects, with repetition is:
\(\overline{C}_{n,k} = \: ^{n + k-1}C_{k} = \dfrac{(n+k-1)!}{k! \times (n-1)!}\)
Thus, 5 people can be in a group. There's 12 people. So we can use combination.
12C5 = 12 * 11 * 10 *9 * 8
12C5 = 792
