Simply plug the number after the semi colon into each question's respective variable.
1. Is k=-1 a solution to this problem?
Is 9(-1)=10-(-1)?
we see that -9=10+1=11 which is not a true equality. since -9 is not 11 then "No" is the correct answer to number 1.
3.
3(-10)÷(-6)=5-(-10) ?
-30÷-6=5+10?
5=15?
No, not true, thus "No" is the correct answer.
5. 8-8=2(8)-16?
Is 0=16-16 ?
Yes!
7.
Is 2(7-2)-5(7)=5(2-7)?
2(5)-35=5(-5)?
10-35=-25
-25=-25
Bingo! Yes.
Answer:
0.7 km
Step-by-step explanation:
Actual distance in cm = 7(10000)
= 70 000 cm
Actual distance in km = <u>0.7 km</u>
Answer:
114 ft per minute
Step-by-step explanation:
To find the speed, take the distance and divide by the time
228 ft/ 2 minutes
114 ft per minute
Answer:
see below
Step-by-step explanation:
||v|| = 3/4
Theta = 30 degrees
The x component is x = ||v|| cos theta
= 3/4 cos 30 =3/4 * sqrt(3) /2 =3 /8 sqrt(3) =.649519053= .650
The y component is y = ||v|| sin theta
= 3/4 sin 30 =.375
Answer:
<u><em>$29.75</em></u>
Step-by-step explanation:
$8.50 for 1 hour
So for <u>3 hours</u>, it will be 8.50 + 8.50 + 8.50 equaling to 25.50
So far the total is $25.50 for 3 hours ONLY!
Now, for half of an hour it will be half of a price, making 8.50 into 4.25
Finally, add $25.50 + $4.25 giving you the totality of $29.75 as the final pay after working for 3 1/2 hours
