Answer:
C) commutative
Step-by-step explanation:
Example: a x b = b x a
Answer:x=-4 and x=4
Step-by-step explanation:
Took the assignment on edg 2020
So,
Her average so far is the sum of the five scores divided by the number of tests she has taken so far.
(87 + 81 + 85 + 90 + 78)/5 = 84.2
(87 + 81 + 85 + 90 + 78)/5 < 85 :(
She will not get into that college if she doesn't increase her average on the last test.
85 - 84.2 = 0.8
0.8(5) = 4.0
On her last test, she needs to score 4 points higher than her current average in order to get into the college.
84.2 + 4 = 88.2
Jessica needs to score at least 88.2 on her last test.
Recall your d = rt. distance = rate * time.
let's say the speed of the current is "c".
keeping in mind that, when the boat is going against the current, the boat is not really going at 2kmh, but instead at " 20 - c ", because the current is subtracting speed from it.
Likewise when is going with the current, is going at a speed of " 20 + c ".
if the boat took say "t" hours on the way over, on the way back it took the slack from the whole 8 hours and "t", namely it took " 8 - t " hours.
Hey there!
(Part 1) <span>
Your question states:
Suppose a car is traveling east on 4th Street and turns onto King Avenue heading northeast. What is the measure of the angle created by the car's turning? Explain your answer.
180</span>°-70°= 110° ✓
This person would be driving
110° degrees. ✓
So, what we would do it do 180° subtracted by 70. We need to find how much he turns onto King Avenue heading northeast. So we do 180° because that would be considered a full half turn, so 180° subtracted by 70 and that would give you
. . .
180° - 70° =
(Part 2)
Your question states:
<span>
Suppose a car is traveling southwest on King Avenue and turns left onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.</span>
This may be a little tricky on this side. These side's are coherent. As we know now that the angel on (King Ave.) was 110°, we would say the on the (3rd angel through King Ave.) that angel as well would be 110° because that is the angel on top. This would mean that they would be the same. But the thing is, we are finding what is the angel when the car is traveling southwest on King Avenue and turns left onto 3rd Street. This angel would be 70° degrees because as we do 70° + 70° + 110° + 110° = 360°.
This is how we would know that this would be that angel going into (<span>3rd Ave).
</span>My steps: 360° - 110° - 110° = 140°.
140° ÷ 2 =
∡70° ✓
Your correct answer would be
Step #3
Your question states:
<span>Suppose a car is traveling northeast on King Avenue and turns right onto 3rd Street. What is the measure of the angle created by the car's turning? Explain your answer.
</span>
Your correct answer would equal 110°. <span>✓</span>
My steps:
360° - 75° - 75° = 210°
210° ÷ 2 =
105° ✓
Your correct answer would be
