Can someone help me?

Answer:

Step-by-step explanation:

The answer is B because if you move two times to the right it gives you 0.09 like the eqution.

But scientific notation requires number without decimal, so the answer cannot be E because 0.9 is a decimal.

Just reminder: B and D have the same result!! just different coefficient

Answer:

Average speed = $\frac{(x+y)}{2}$ miles per hour

Step-by-step explanation:

Formula to calculate the average speed of an object is,

Average speed = $\frac{\text{Total distance covered}}{\text{Time taken to cover this distance}}$

If I travel with the speed of x mph for t hours,

Total distance covered = Speed × Time

= $x\times t$

= $xt$ miles

Similarly, if I travel with the speed y mph for t hours,

Total distance covered = $yt$ miles

Total distance covered by me = $(xt+yt)$ miles

Total time taken to cover this distance = $t+t$

= $2t$ hours

Therefore, expression for the average speed will be,

Average speed = $\frac{xt+yt}{2t}$

= $\frac{(x+y)t}{2t}$

= $\frac{x+y}{2}$ miles per hour

Find the measure of the angle indicated in bold, which is 6x

DerKrebs [107]

The measure of that angle is 60 degrees. To solve this, first, you set the 2 measures equal to each other, because they are congruent. So your equation is 6x=5x+10. Subtract 5x from both sides, leaving you with x=10. Lastly, substitute 10 for x. You multiply 6 by 10, which equals 60.

Find an explicit formula for the geometric sequence 3,15,75,375 <br> a(n)=

DENIUS [597]

Answer:

an = 3(5)^(n-1).

Step-by-step explanation:

15 / 3 = 5

75/15 = 5

375/75 = 5

So the common ratio is 5.

First term a1 =3

an = a1 r^(n-1) is the explicit formula.

so here we have:

an = 3(5)^(n-1).
