Fern knitted 20 scarves over 5 nights. After 8 nights of knitting, how many scarves would fern have made in total.

Studentka2010 [4]

Answer:

Fern will knit 32 scarves in 8 nights.

Step-by-step explanation:

Number of scarves knitted by Fern in 5 night = 20

Relation between number of scarves knitted and number of nights is proportional,

Therefore, Number of scarves knitted (s) ∝ Number of nights spent to knit the scarves (n)

s ∝ n

s = kn

k = $\frac{s}{n}$

Here, k = proportionality constant

For s = 20 and n = 5,

k = $\frac{20}{5}$

k = 4 scarves per night

For 8 nights, by using the same proportionality rule,

k = $\frac{s}{8}$

4 = $\frac{s}{8}$

s = 32 scarves

Therefore, Fern will knit 32 scarves in 8 nights.

A tiny songbird called the blackpoll warbler migrates each fall from North America. A tracking study showed one bird flew from V

Alexus [3.1K]

Answer:

Step-by-step explanation:

Given the map coordinates o a bird during travel from Vermont at cordinate (63,45) toto Venezuela at map coordinates (67,10). In order to know how far the bird has travelled, we need to find the distance between the two coordinates first using the formula;

D = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Given x₁ = 63, y₁ = 45, x₂ = 67, y₂ = 10

$D =\sqrt{(67-63)^2+(10-45)^2}\\ \\D = \sqrt{4^2+(-35)^2} \\\\D = \sqrt{16+1225} \\\\D = \sqrt{1241} \\\\D = 35.2278$

If each map coordinate represents 75 kilometers, then the birds distance in km will be 75*35.2278 = 2642.087km

Hence the birds distance in km will be 2642km to the nearest kilometers

A keycode must contain 2 letters and 3 numbers. The letters may be any letter of the alphabet. The numbers should be any number

OverLord2011 [107]

The English alphabet contains 26 letters (a, b, c, ...y, z).

The digits from 0 to 9 are a total of 10.

A keycode contains 2 letters, and 3 numbers, for example:

AB 598; MM 139; NT 498; ...

So there are 26 possible choices for the first letter, which can combined with any of the 26 possible choices for the second letter, so there are a total of

26*26=676 possible pairs of letters.

Similarly, the 10 possible choices for the first number, which can be combined with the 10 possible choices for the second number, and the 10 possible choices for the third number make a total of :

10*10*10=1,000 possible triples of numbers.

Any of the 676 possible pairs of letters can be combined with any of the possible 1,000 triples of numbers. This makes a total of

676*1,000=676,000 keycodes.

Answer: 676,000

The coefficient of the ab term is

Jlenok [28]

Answer:

A coefficient is an integer that is written along with a variable or it is multiplied by the variable. For example, in the term 2x, 2 is the co-efficient.

Those variables which do not carry any number along with them, have a coefficient 1. For example, the term y has coefficient 1.
