Answer is A, (√12+√6)(√6-√10)
The answer would be 4. It would be 4 because 4x16=64. And 0-4x3=-12.
Answer:
It says or, so you can answer any however the answer to time would be 4 years or so
Step-by-step explanation:
10x5 = 50
50x50 = 2500
2500x.4= 1000
1000/250=4
4
So I check as best as I could from the paper as it would get kind of blurry as you'd zoom. But as reviewing everything, I see that everything actually seems to be actually correct. I wanted to consider the last question, as it would say that would be the percent of 7/8 to 3/4. Your answer that you have done in this would be 6/8 based by knowing that 7/8 and 3/4 are almost whole numbers, and also, sense this would be the case, we would have to brainstorm it, and thing that maybe the answer would then have to have the same denominator as the smaller fraction, and also move two digits down as both numbers are almost a whole number. So in this question, I do give credit. You did great. And also, as for the other questions, the multiplication seems to also be top notch, and everything also seems to be answered completely and great.<span />
Step-by-step explanation:
a) The scale 3:24 = 1:8 so if the scale drawing is 5" tall, then the building's actual height is 5×8 = 40 ft.
b) The ratio of the cement to sand is 1:3 so if you have 24 buckets of sand, that means you need 24/3 = 8 buckets of cement.
c) The ratio at which the money is to be distributed is 5:2:4:3. So the money is to be partitioned into 14 (=5+2+4+3) parts so that A get (5/14) of the money, B gets (2/14), C gets (4/14) and D gets (3/14). If C gets R1000 more than D then we can write
Solving for M, which is the total sum of money, we get
Now that we know how much money is involved we can now solve how much money B gets:
