He is left with 12
1/5 of 10 is 2 so he was left with 8
2*2 is 4, and 8+4 is 12!
Answer:
Step-by-step explanation:
(0,2). y=mx+b or 2=-2 × 0+b, or solving for b: b=2-(-2)(0).
Answer:
287
Step-by-step explanation:
The lateral surface area of a cone is r*pi*l, where l is the slant height. This is much like the formula of a square pyramid, which is a good way to understand this formula. But that aside, Lets plug in some values:
We know the diameter is 12 so r = 6.
Now lets find the slant height. We can draw a right triangle using the height, radius, and slant height. So we get, sqrt(6^2 + 14^2 ) = l, by Pythagorean's theorem. Therefore, l = sqrt(232) which is roughly 15.23
So we have 6*pi*15.23 which is roughly 287
Answer:
21/10 mph
Step-by-step explanation:
When you divide a fraction with another fraction, the number after the division sign gets flipped (meaning that the numerator and denominator switch so 1/2 would be 2/1)
So using that we can solve this:
7/5 / 2/3
7/5 * 3/2
21/10 miles per hour
<span>2x − 3y − z
</span><span> x = −2,
</span><span> y = 3,
</span><span> z = −2
What we must do is replace the values given in the equation. We have then replacing:
</span> 2*(-2) - 3*(3) - (-2) = -11
The answer is -11
