I'm not sure about questions 4 and 7, but they may be correct.
I couldn't because I couldn't see the 2nd question
Answer:
w=9
Step-by-step explanation:
Our equation is: 8w-15=57
Add 15 to both sides
-15 is now gone because we added 15 so it would be zero
and we have 72 because 15 plus 57 is 72
Now we have:
8w=72
Divide by 8 on both sides
8w cancels out to just w
and 72 divided by 8 is 9
And you're left with:
w=9
Let S=larger square side and s=smaller square side. The area between the larger and smaller is simple the larger area minus the smaller area. The area of any square being s^2. So our remaining area is:
A=S^2-s^2
A=144-49=95 cm^2
Answer:
6 pk noisemakers (6 x 5 = 30 noisemakers)
1 pk balloons (1 x 30 = 30 balloons)
Step-by-step explanation:

Answer:
The answer to your question is:
a) sin Ф = -3/√10
b) cos Ф = 1/√10
c) tan Ф = -3
Step-by-step explanation:
See the picture below
just remember
sin Ф = opposite / hypotenuse
cos Ф = adjacent / hypotenuse
tan Ф = opposite / hypotenuse
