oof its asking for it to be 20 words longs or something like that oof thats why im typing this.
Answer:
t < 0 and t > 140
Step-by-step explanation:
It is given in the question that fluid is not a liquid if its temperature is above 140°C or below 0°C.
So, the inequality that satisfies the temperature at which the fluid is liquid will be given by 140 ≥ t ≥ 0.
Now, the compound inequality for the temperature t when the fluid is not liquid is t < 0 and t > 140. (Answer)
1. Given any triangle ABC with sides BC=a, AC=b and AB=c, the following are true :
i) the larger the angle, the larger the side in front of it, and the other way around as well. (Sine Law) Let a=20 in, then the largest angle is angle A.
ii) Given the measures of the sides of a triangle. Then the cosines of any of the angles can be found by the following formula:
a^{2}=b ^{2}+c ^{2}-2bc(cosA)
2.
20^{2}=9 ^{2}+13 ^{2}-2*9*13(cosA) 400=81+169-234(cosA) 150=-234(cosA) cosA=150/-234= -0.641
3. m(A) = Arccos(-0.641)≈130°,
4. Remark: We calculate Arccos with a scientific calculator or computer software unless it is one of the well known values, ex Arccos(0.5)=60°, Arccos(-0.5)=120° etc
Answer:
4.5 or 4 and a half
Step-by-step explanation:
9/10 divided by 2/10
put 2/10 into it's reciprocal and multiply it by 9/10
10/2 * 9/10
10 9
_ * _
2 10
^ (visualization)
multiple into 90/20, divide numerator and denominator by 10 to get 9/2
9/2 is 4.5
