Answer:
21
Step-by-step explanation:
It might be 21/30 , hope it helps though :)
Your inequality is (x being number of people):
175≥35+10x+3x
First, combine like terms so your new inequality is:
175≥35+13x
Then subtract 35 from both sides which makes it:
140≥13x
then divide 140 by 13 making it:
<span>10.769≥x
</span>But because you can't have .769 of a person the actual answer is 10
then you have to subtract 1 because he isn't including himself and there is the answer!:
9≥x
Answer:
Percent increase is 17.6%
We still have to pay 7.50 with the coupon
Step-by-step explanation:
Percent increase = (new- original)/original *100%
= (10-8.5)/8.5 * 100%
= 1.5/8.5 * 100%
= 17.6470588%
Round to the nearest tenth
17.6%
This is an increase since the cost went up.
If we have 25% off, we still have to pay (100%-25%) = 75%
10 *.75 = 7.50
We still have to pay 7.50 with the coupon
Doesn’t make sense.. how much can fit into one packet
Answer:
26.8°
Step-by-step explanation:
The cosine of an angle is the ratio of the adjacent side of the triangle in which the angle is formed to the hypotenuses side of the triangle. The cosine of the angle gives the ratio of these sides. However, the arc cosine of the ratio gives the angle measured in degrees.
If cos B = 0.8926
then arc cosine 0.8926 which may be expressed as cos-1 0.8926 will give the value of B.
B = cos-1 0.8926
= 26.8°
