kendra knits hats. She starts with 3 3/4 yd of yarn. After knitting for 5 1/4 h their is 1 1/8 yd of yarn left. At what rate doe
nadezda [96]

Answer:

The rate is  1 ÷ 2 yards per hour

Step-by-step explanation:

The computation of the rate does the amount of yarn changes is given below:

= 3 3 ÷ 4 - 1 1 ÷8

= 15 ÷ 4 - 9 ÷ 8

= 21 ÷ 8 yards

 Now divide the above fraction by the number of hours

= 21 ÷ 8 yards ÷ 5 1 ÷ 4

= 21 ÷ 8 ×  4 ÷ 21

= 1 ÷ 2 yards per hour

Hence, the rate is  1 ÷ 2 yards per hour

The same would be relevant

Imagine that you need to compute e^0.4 but you have no calculator or other aid to enable you to compute it exactly, only paper a
labwork [276]

Answer:

0.0032

Step-by-step explanation:

We need to compute e^{0.4} by the help of third-degree Taylor polynomial that is expanded around at x = 0.

Given :

e^{0.4} < e < 3

Therefore, the Taylor's Error Bound formula is given by :

$|\text{Error}| \leq \frac{M}{(N+1)!} |x-a|^{N+1}$   , where $M=|F^{N+1}(x)|$

         $\leq \frac{3}{(3+1)!} |-0.4|^4$

         $\leq \frac{3}{24} \times (0.4)^4$

         $\leq 0.0032$

Therefore, |Error| ≤ 0.0032

Setler79 [48]

Answer:

The answer is  8x - 3x + 2 -x =<u> 4 </u>x + <u>2 </u> .

Step-by-step explanation:

Given:

8x - 3x + 2 -x = __ x + __

Now, to write a number in each blank to complete each equation so that it has the requested number of solutions.

So, to solve the equation:

8x-3x+2-x

So, we add  the variables:

5x+2-x

And, then subtract it:

4x-2.

Thus, it remains:

4x-2.

So the complete equation is:

8x - 3x + 2 -x =<u> 4 </u>x + <u>2 </u>

Therefore, the answer is  8x - 3x + 2 -x =<u> 4 </u>x + <u>2 </u> .
