Write the repeating rational number 0.828282… as a fraction.

vivado [14]

Answer:

Step-by-step explanation:0.828282 = 0.828282/1 = 8.28282/10 = 82.8282/100 = 828.282/1000 = 8282.82/10000 = 82828.2/100000 = 828282/1000000

And finally we have:

0.828282 as a fraction equals 828282/1000000

Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. What equations can be used to find the number of each of bal

fredd [130]

We can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon for Myer

<u>SOLUTION: </u>

Given, Myers balloons cost $1.25 each, and latex balloons cost $0.75 each. We have to find what equations can be used to find the number of each of balloon in a bunch of 18 balloons that costs $19?

Let number of myers balloons be m, and number of latex balloons be n.

Then m + n = 18 ⇒ (1)

And according to given information,

$1.25 x number of myers ballons + $0.75 x number of latex balloons = $19

⇒ 1.25m + 0.75n = 19 ⇒ (2)

Hence, we can use the equations m + n = 18 and 1.25m + 0.75n = 19 to find number of each balloon.

Now, (1) ⇒ m = 18 – n. substitute these values in (2)

(2) ⇒ 1.25(18 – n) + 0.75n = 19

22.5 – 1.25n + 0.75n = 19

1.25n – 0.75n = 22.5 – 19

0.5n = 3.5

n = 7

Then, m = 18 – 7 ⇒ m = 11.

So, 11 myers balloons and 7 latex balloons.

A proton initially has and then 8.00 s later has (in meters per second). (a) For that 8.00 s, what is the proton's average accel

svet-max [94.6K]

Answer:

Some details are missing in the question, here are the details ; A proton initially has v = -6.5i + 17j + 13k and then 8.00s later has v = -2.8i + 17j - 9.3k (in meters per seconds).

a) proton's average acceleration in unit vector notation = 0.46i - 2.78k

b) Magnitude = 2.85m/s2

c) angle between and the positive direction of the x axis = 279.39 degree (counter clockwise)
