Answer:
Fastest wind speed ever recorded
That is, however, a patch on the top speed ever reached by an aircraft, a record held by the Lockheed Blackbird, which tickled 2,193mph in 1976
Step-by-step explanation:
Answer:
- 39/8y
Step-by-step explanation:
First you need to find a common denominator:
There is already a y in both denominators, so you don't have to worry about that. Since only one denominator has an 8, the other needs to have an 8, so you need to multiply the first fraction by 8 → - 4/y * 8 = - 32/8y
From here you can subtract the numerators:
- 32/8y +(- 7/8y) = - 39/8y
Because you are adding a negative to a negative, it makes the number mroe negative
I hope this helps!
So, this is kinda similar to the other I helped you with:
<span>So r is the radius of the disk. The area is known and equal to 100Pi; so
100Pi = Pi r2
Now for r: r = 10
Circumference = 2 PI r = 20 Pi
I hope this helped!</span>
The answer is 6 positive tiles.
Answer:
X=-3, y=-4, z=-5
Step-by-step explanation:
X-4y+3z=-2......(1)
2x-y+4z=-22....(2)
3x-3y+4z=-17.....(3)
-2(1)+(2) and -3(1)+(3) we get:
7y-2z=-18....(4)
9y-5z=-11.....(5)
Now 5(4)-2(5) we get:
17y=-68 so
y=-4
Put y=-4 in (4) we have:
-28-2z=-18, then 2z=-10, so we have:
z=-5
Now put y=-4 and z=-5 in (1) we get:
x+16-15=-2, then
X=-3
