Answer:
m<I=57
m<J=57
m<K=66
Step-by-step explanation:
All the angles in a triangle add up to 180 degrees.
m<I= 3x+18
m<K= 5x+1
m<I is congruent to m<J.
We can plug the information we already know into the equation.
3x+18+3x+18+5x+1=180
11x+37=180
Subtract 37 from both sides.
11x=143
x=13
Now, we can find out what the angles are.
m<I= 3x+18
m<I=3(13)+18
m<I=39+18
m<I=57
We know that m<I=m<J, so they are both equal to 57 degrees.
m<J=57
Now for m<K:
m<K=5x+1
m<K=5(13)+1
m<K=65+1
m<K=66
We know this is correct because 57+57+66=180.
So we want to find how much more space the logo took up.
So just subtract the location info from the logo space.
2/7 - 1/10
To subtract, you just want to find a common denominator. In this case it would be 70.
2/7 * 10/10 - 1/10 * 7/7
20/70 - 7/70
Then just subtract.
13/70
So that's the fraction. For the percent, just divide.
13/70 = 0.186 ish
Or, 18.6% ish
Answer:
17
Step-by-step explanation:
As 2 phones are defective from a group of 98 that were checked, you can determine a percentage:
2/98= 2%
This indicates that 2% of the phones are likely to be defective and because of that you can find 2% of 850:
850*2%= 17
According to this, 17 phones are likely to be defective.
Answer:
Step-by-step explanation:
slope-intercept formula is y = mx+b
3y + 2x - 4 = 1
3y + 2x = 5
3y = -2x +5
y = (-2/3)x + 5/3
