Yea Any integer can be written as a fraction! Just put that integer as the numerator of a fraction with a denominator

Answer:

Yes

Step-by-step explanation:

Any integer can be turned into a fraction.

For example, you have -2, to turn this integer into a fraction all you have to do is place -2 as a numerator and 1 as the denominator:

$-2 = \frac{-2}{1} = -\frac{2}{1}$

You can also change both values of the numerator and the denominator by multiplying the whole fraction by 2 only (to maintain the same value of -2):

$-\frac{2 * 2}{1 * 2}$ $= -\frac{4}{2}$ which means $-2 = -\frac{4}{2} = -\frac{8}{4} = -\frac{16}{8}$ ...and the pattern goes on.

Matter of fact, this method works with any integer not only the negatives.

A 140 kg camera is suspended by two wires over a 40 metre wide football field to get shots of the action from above. At one poin

Please red the answer below

Step-by-step explanation:

In order to determine the length of each cable you use the Newton second law for each component of the forces involved in the situation.

For the x component you have:

$T_1cos\theta_1-T_2cos\theta_2=0$ (1)

T1: tension of the first cable = 1500N

T2: tension of the second cable = 800N

θ1: angle between the horizontal and the first cable

θ2: angle between the horizontal and the first cable

For the y component you have:

$T_1sin\theta_1+T_2sin\theta_2-W=0$ (2)

W: weight of the camera = Mg = (140kg)(9.8m/s^2) = 1372N

You can squared both equations (1) and (2) and the sum the two equations:

$T_1^2cos^2\theta_1=T_2^2cos^2\theta_2\\\\T_1^2sin^2\theta_1=T_2^2sin^2\theta_2-2WT_2sin\theta_2+W^2$

Then, you sum the equations:

$T_1^2(cos^2\theta_1+sin^2\theta_1)=T_2^2(sin^2\theta_2+cos^2\theta_2)-2Wsin\theta_2+W^2$ (3)

Next, you use the following identity:

$sin^2\theta+cos^2\theta=1$

and you obtain in the equation (3):

$T_1^2=T_2^2-2WT_2sin\theta_2+W^2\\\\sin\theta_2=\frac{T_2^2-T_1^2+W^2}{2WT_2}=\frac{(800N)^2-(1500)^2+(1372N)^2}{2(800N)(1372N)}=0.066\\\\\theta_2=sin^{-1}0.066=27.23\°$

With this values you can calculate the value of the another angle, by using the equation (1):

$\theta_1=cos^{-1}(\frac{T_2cos(27.23\°)}{T_1})=cos^{-1}(\frac{(800N)(cos27.23\°)}{1500N})\\\\\theta_1=61.69\°$

Now, you can calculate the length of each cable by using the information about the width of the football field. You use the following trigonometric relation:

$l_1cos\theta_1=40-d\\\\l_2cos\theta_2=d\\\\$

d: distance to the right side of the field

By using the cosine law you can fins a system of equation and then you can calculate the values of l1 and l2.

Edith needs 65 yards of yarn to knit a baby hat and 580 yards of yarn to knit a baby blanket. A ball of yarn contains 420 feet o

umka2103 [35]

Answer:

Step-by-step explanation:

There are 3 feet in a yard, so 420 feet is 420/3 = 140 yards.

The total number of yards Edith needs is ...

65 yd + 580 yd = 645 yd

So, the total number of balls of yarn Edith needs is ...

(645 yd)/(140 yd/ball) ≈ 4.61 balls

Edith needs to buy 5 balls of yarn to make her projects.

First let's model the carpet as a rectangle.
The diagonal of a rectangle is given by:
d = root ((L) ^ 2 + (W) ^ 2)
Where,
L = long
W = width.
Clearing the width we have:
d = root ((L) ^ 2 + (W) ^ 2)
d ^ 2 = (L) ^ 2 + (W) ^ 2
(W) ^ 2 = (d) ^ 2- (L) ^ 2
W = root ((d) ^ 2- (L) ^ 2)
Substituting the values
W = root ((root (89)) ^ 2- (8) ^ 2) = 5
answer
The width of the carpet is
5 feet
