a silkworm winds its cocoon out of one long silk fiber. to make silk thread, 3 to 10 of these silk fibers are unwound from their

cocoons and combined into aa single thread with a typical length of 300 yards. choose a reasonable number of silk fibers in a thread write an equation to find the total length of the silk fibersused in 300 yards of the thread

Answer:

Possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.

Step-by-step explanation:

Let the length of the silk fiber = x yards.

Let the number of silk fibres = a.

It is given that the silk fibers between 3 to 10 yards are combined to form a silk thread of 300 yards.

So, we get the equation,

ax=300, where 3\leq a\leq 10

i.e. x=\frac{300}{a}, 3\leq a\leq 10

So, the possible values of 'a' are 3, 4, 5, 6 an 10.

Thus, the possible lengths of the silk fibre 'x' are 100, 75, 60, 50 and 30 yards respectively.

Answer:

It depends on what property you use

Step-by-step explanation:

If you use the distributive property then you would get 5x-30

If you factor you would get 5(x-6)

Write an equation for the translation of y=|x|. 2 units down.

B. Y = <span>|x| - 2
when moving left or right...meaning moving horizontally.......the number is added inside the parenthesis. 

This one is moving up or down ....meaning moving horizontally........so the number is added outside the parenthesis. If it moves up then add(+)..........if it moves down then subtract(-). The formula used for horizontal shifts is, y=lXl + k
.Here k will become negative or remain positive based on the given data.

Now,
It's a horizontal shift, so we can eliminate C and D.
 It moves down so we will subtract and therefore we can eliminate A

so the answer is B.
 lets check our answer by using the formula

Y = lxl + k
moves 2 units down so our k = (-2)
Y = lxl + (-2)  [substitute k]
Y = lxl - 2

What is the value of sin(t) if cos(t)=0.1, and t is in quadrant 1
Marizza181 [45]

Answer:

sin(t)=\frac{\sqrt{99}}{10}

Step-by-step explanation:

Remember that

If angle t belong to the First Quadrant

then

The value of sin(t) and cos(t) are positive values

we know that

sin^2(t)+cos^2(t)=1 ---> by trigonometric identity

we have

cos(t)=0.1=\frac{1}{10}

substitute

sin^2(t)+(\frac{1}{10})^2=1

sin^2(t)+\frac{1}{100}=1

sin^2(t)=1-\frac{1}{100}

sin^2(t)=\frac{99}{100}

sin(t)=\frac{\sqrt{99}}{10}
