<span>1. The problem says that the is ratio 1:3:5 by weight and Talil wants to make 180 kg of concrete mix.
2. Therefore, you have:
1+3+5=9
180 kg/9=20 kg
3. Each of the 9 parts of the ratio weights 20 kg. So, to make 180 kg of concrete mix, he needs:
1x20 kg=20 kg of cement
3x20 kg=60 kg of sand
5x20 kg=100 kg of gravel
4. Talil has:
15kg of cement (Not enough)
85kg of sand (More than enough)
100kg of gravel (Enough)
</span><span>
Does Talil have enough cement , sand and gravel to make concrete mix?
</span><span>
The answer is: No, she does no have </span>enough cement , sand and gravel to make concrete mix.
I think 11 miles but I’m not 100% hope I helped ;)
6.24x10^6 ( the first one)
What the above statement is saying is:
If the number is 4, find the difference between the square of the number (the number is 4) and the number itself (the number is still 4).
The square of the number is:
The number^2
= 4^2
= 4 × 4
= 16
The difference between the square of the number and the number is:
The number^2 - The number
= 16 - 4
= 12
Hope this helps! :)
Answer:
C ig.
Step-by-step explanation:
well, it's not a right angle (90 degrees), it's not a 45 degree angle, and it's not a straight angle (180 degrees), so it's not enough info
