I need to know what was the number of sharpened pencils at 7:07 am?

Vanyuwa [196]

You wrote the equation wrong- he starts with 9 pencils so that's a constant and he sharpens 11 pencils for every minute. The equation would be 9+11x with x being the amount of minutes, which in this case is 7. So you just substitute and solve.

9+11x

9+11(7)

9+77

Hope this helps!

Need help doing this, show steps if you could

Anna71 [15]

Answer:

p = (0.5 , 5)

Step-by-step explanation:

D(-6 ,4) E(7 ,6)

For the line FP to be a median, the point p must have the intermediate value at x and at y between points D and E

p = (Dx + Ex)/2 , (Dy + Ey)/2

p = (-6 + 7)/2 , (4 + 6)/2

p = 1/2 , 10/2

p = (0.5 , 5)

This is because for a medium to be the point p has to be right in the middle of the other 2 vertices

Grace and Zoe like to jump rope grades jump 66 times a minute Zoe jumps 56 times a minute they both Count Their jumps today and

san4es73 [151]

Answer:

Grace jumps for 9 minutes.

Zoe jumps for 12 minutes.

Step-by-step explanation:

Let the time for which Grace jumps the rope = $x$ minutes

Let the time for which Zoe jumps the rope = $y$ minutes

As per question statement:

$x+y=21 ..... (1)$

Number of times Grace jumps in one minute = 66

Number of times Zoe jumps in one minute = 56

Number of times Grace jumps in $x$ minutes = 66

Number of times Zoe jumps in $y$ minutes = 56

As per question statement:

$66x+56y=1266 ...... (2)$

Multiplying equation (1) with 66 and subtracting equation (2) from it:

$10y = 1386 - 1266\\\Rightarrow 10y=120\\\Rightarrow y =\bold{12\ min}$

By equation (1):

$x=21-12=\bold{9\ min}$

Therefore, the answer is:

Grace jumps for 9 minutes.

Zoe jumps for 12 minutes.
