Answer:
S' (1,-2)
S'' (0,0)
Step-by-step explanation:
hopefully this is correct (:
100 = 10 x 10 = 10<span>2 </span>
7.5" if the width is now 18 that means its value increased by 3 so multiply 2.5 by 3 and its = to 7.5
Answer:
2. one angle is 108, and other is 72
3. x is 12
Step-by-step explanation:
the ratio is 3:2.
3x + 2x = 180
5x = 180
x = 36
36 x 3 = 108
36x 2 = 72
so that is why the two angles re 108and 72.
for the last question, 37 plus 41 plus x = 90
37 plus 41 is 78
90 - 78 = 12
so that is why x is 12.
The answer to that question is the sum of the hours he studied for on both days, which will be 1/4 + 3/8.
However, we cannot add fractions with different denominators. In this case, it's 4 and 8.
So if we want to add them, we must make the denominators similar to each other. How to make 4 into 8? We multiply it by 2: 4 x 2 = 8.
BUT when we multiply fractions, we must multiply both the numerator and the denominator by the same number to keep its original value. In this case, if you want to multiply 4 by 2, you must also multiply 1 by 2.
=> SO to make 1/4 into y/8, we will multiply it like this (1 x 2) / (4 x 2) = 2/8
Now we can add the 2 fractions together. 2/8 + 3/8 = (2 + 3)/8 = 5/8. THIS IS YOUR ANSWER.
TL;DR: He studied 5/8 (or 0.625) hour altogether on both days.
