Answer:
surely it's 200 marbles bc 2/4 is equal to 1/2 and if u then half 400 you get 200
Step-by-step explanation:
The answer of 3 × 1 3\4 is 21\4 or 5 1/4
20, 20, 20, 30, 20
Tip for rounding nearest 10th: if the 2nd number is above 5 it’s the one above, if it’s below 5 it’s the one below.
Answer:
Absolute error is 0.05 cm.
Step-by-step explanation:
Given:
Actual length = 12.25 cm
Measured length = 12.2 cm
We need to find Absolute error.
Solution:
Now we can say that;
Absolute error is equal to measured length minus Actual actual.
framing in equation form we get;
Absolute error = 
Hence Absolute error is 0.05 cm.
Answer:
factors are basically numbers that can multiply by another number to get a certain number
Step-by-step explanation:
for example, the factors of 12: 1,2,3,4,6,12
you should count from the lowest to highest number to make it easier for u.
look at 1 and 12 in the sequence. 1 x 12 = 12
now look at 2 and 6. 2 x 6 = 12
now look at 3 and 4. 3 x 4 = 12
see what i mean?
an example of a non-factor would be 5. 5 can't multiply by anything to get 12. You need to find numbers between 1 and the certain number (12 in this example) and you need to find numbers that can multiply by another number to get that certain number but u can't go beyond the certain number. 7 can't multiply by anything to get 12. if u still don't understand, here is an easier way to help u.
the best thing to do is write the numbers from 1 - 12. 1 2 3 4 5 6 7 8 9 10 11 12
once u do that, you need to ask yourself: which numbers can multiply to get 12? 1 can multiply by a number to get 12. 2 can. 3 can. 4 can. <em>5 can't. </em>once you find a number that you can't multiply by, that is <em>not </em>a factor of the certain number you're looking for.
Hope this helps you :D
