<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.
Answer:
C. x<18
Step-by-step explanation:
If you substituted the inequalities with 5, the logical one is x<18.
Especially since 5 is less than 18, it isn;t greater than or less than 2,9, or 42.
Answer: -133
Step-by-step explanation:
1. 4(-6^2+3)-2(1/2)
v
2. 4(-36+3)-2(1/2)
v
3. 4(-33)-2(1/2)
v v
4. -132-1
v
5. -133
Since the area of any thing is length time width, we can divide 4864 by 152 to get the width of the garden. This gives us 32. Now we need to add 152 + 152 + 32 + 32 to get our total feet of fencing necessary. This would give us 368 feet of fencing.
Answer:
88°
Step-by-step explanation:
Since we have 2 parallel lines, first we use the Corresponding Angles Postulate.
Since angle 2 is corresponding to the 92° angle,
angle 2 = 92°
Now we know that angle 1 and angle 2 are supplementary.
This means:
angle 1 + angle 2 = 180°
<em>(substitute known values)</em>
angle 1 + 92 = 180
<em>(subtract 92 on both sides)</em>
<h2>
angle 1 = 88°</h2><h2>
</h2>
Hope this helps, please say thanks if it does!
