Answer:
W = - 14
Step-by-step explanation:
13W - 2(4W + 1) = W - 58
13W - 8W - 2 = W - 58
13W - 8W - W = 2 - 58
4W = - 56
W = - 56 : 4
W = - 14
Answer:
y = - 0.8
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when y = - 4, x = 10, then
- 4 = 10k ( divide both sides by 10 )
- 0.4 = k
y = - 0.4x ← equation of variation
When x = 2 , then
y = - 0.4 × 2 = - 0.8
Correct answer: D. Upon Itself
A line segment has an angle that is exactly 180°. As perpendicular lines are lines meeting at the right angle, or 90°. If we then use paper folding to construct a line perpendicular to a given line, the given line should be directly above each other once folded.
Answer: 
My step-by-step explanation:
- <u><em>We would use the formula πr2 (pi x radius x radius)
</em></u>
<em> </em><u><em>2.In this problem we were given the diameter of 6, in order to find the radius, you just divide by 2</em></u>
- <u><em>
And so we find: 6mm÷2=3mm
</em></u>
3. So now that we have our radius, we can just plug the numbers into the formula. So this would be:
- <u><em>πr2= 3.14 x 3 x 3= 28.26mm2</em></u>
<u><em /></u>
<u><em /></u>
Hope this helps you!
