Hazel knits 5 centimeters of scarf eachnight. After 5 nights of knitting, how manycentimeters of scarf will Hazel have knit into

natta225 [31]

Answer:

Hazel will have knitted 25 centimeters of the scarf

SOLUTION

Problem Statement

We are told Hazel knits 5 centimeters of scarf every night for 5 nights. We are required to find the length of the scarf Hazel will have knitted after 5 nights.

Solution

We are told Hazel makes 5 centimeters of scarf every night. Thus, for each night up till 5 nights, we just need to add the length of scarf Hazel has made.

Let us count for each night.

Night 1:

Hazel makes 5 centimeters of the scarf.

Night 2:

Hazel makes extra 5 centimeters, which means she has made:

$\begin{gathered} (5+5)\text{centimeters} \\ =10\text{ centimeters} \end{gathered}$

Night 3:

Hazel makes extra 5 centimeters, which means she has made:

$\begin{gathered} (10+5)\text{centimeters} \\ =15\text{ centimeters} \end{gathered}$

NIght 4:

Hazel makes extra 5 centimeters, which means she has made:

$\begin{gathered} (15+5)\text{centimeters} \\ =20\text{ centimeters} \end{gathered}$

NIght 5:

Hazel makes extra 5 centimeters, which means she has made:

$\begin{gathered} (20+5)\text{centimeters} \\ =25\text{ centimeters} \end{gathered}$

Final Answer

Thus, Hazel will have knitted 25 centimeters of the scarf

Find the length of the missing side. Leave your answer in simplest radical form. *

choli [55]

Answer:

About 14

Step-by-step explanation:

For this you use the pythagorean theorem, which says a(a) + b(b) = c(c)

The sides that make the right angle are legs which is A and B

The other side is the hypotenuse which is C

So you set it up as

11(11) + b(b) = 18(18)

121 + b(b) = 324

324 - 121 = 203

so b(b) = 203

but 203 is b squared so you need to find the square root of 203 which is about 14.2478.

If you round that it is 14

Check

11(11) + 14(14) = 18(18)

121 + 196 = 324

317 = 324

Answer: 385

Given: error: 6 months, standard deviation = 5 years is 60 months

Step 1: find the minimal sample size ‘n’ for 95% confidence interval

1-0.95= 0.05

0.05/2= 0.025

Step 2:
1-0.025= 0.975

Estimate square root of 12 to the nearest tenth. A 4.5 B 3.9 C 4.1 D 3.5

Sholpan [36]

Answer:

3.5

Step-by-step explanation:

As a first approximation of the square root, you can look at the integers relating the given number to the next lower square number. The next lower square number is 3^2 = 9.

12 = n^2 +r = 3^2 +3 . . . . . n = 3, r = 3

The approximate square root is ...

n +r/(2n+1) = 3 +3/7 ≈ 3.429

This value tends to be a little low. Alternatively, the root can be estimated as ...

n +r/(2n) = 3 +3/6 = 3.5

This value tends to be a little high.

A reasonable estimate of √12 is 3.5.

Of course, your calculator can tell you instantly that the root is about 3.464102, close to 3.5.

Additional comment

The relation we used above simplifies the work of linear interpolation between the points (9, 3) and (16, 4) on the square root curve. For some n between 9 and 16, the interpolated root value r would be found from ...

(n -9)/(16 -9) = (r -3)/(4 -3)

(n -9)/7 = (r -3)/1

r = 3 +(n -9)/7 = 3 +(12 -9)/7 = 3 +3/7 . . . . as above

Note that "r" is used for "root" in this discussion. In the above answer, "r" is used for "remainder."
