Answer:

the answer is 36654.52

Step-by-step explanation:

alright so if there are 86400 seconds in a day we substract 28800 bc thats how many seconds we have in 8 eight hours. That is 57600. divide it by 22, which is 2618.18. And multiply it by 14 bc thats how many times he blinks in 22 seconds. 36654.52

Step-by-step explanation:

24hours=86400seconds

8hours =28800seconds

Sam sleeps for 28800second

so 86400-28800=57600seconds.

Sam is awake for 57600seconds.

14blinks in 22seconds

xblinks in 57600seconds.

cross multiply

we have

22x = 806400

x=36654.5

Sam blinks for 36654.5 in a day

daniiel is currently 26 years older than his son. in 6 years he will be three times older than his son. how old are both of them

Molodets [167]

Answer:

Daniiel is 33 years old.

The son is 7 years old.

Step-by-step explanation:

x+26=3x

The x represents the son.

To solve for x:

-26=x-3x

-26=-2x

x=13

Since the father will be 3 times his son's age in six years we subtract 6.

x=7

This means the son is 7 years old as of right now. To find the father's age you do 7+26=33

Genrish500 [490]

Answer:

660

Step-by-step explanation:

First, to find out how much money they have collected so far, you need to add 7100 + 1300 which is 8400. 8400= $8.40. So now you know that they have collected 8.40, you need to subtract 1500-840 which = 660

Hope this helps!

If M is the midpoint of PQ and X is the midpoint of PM then PX = a PQ Which statement is True? a is equal to 1 a is equal to 1/2

garik1379 [7]

Answer:

D. a is equal to $\frac{1}{4}$

Step-by-step explanation:

Let us assume that segment PQ is 8 units, so that its midpoint M is at 4 units to both P and Q.

Given that X is the midpoint of PM, this implies that X is at 2 units to both P and M.

Then;

PX = aPQ

⇒ = a x 8

= 8a

Therefore, a must be equal to $\frac{1}{4}$ , so that;

PX = 8a

= 8 x $\frac{1}{4}$

= 2 units

Thus, a is equal to $\frac{1}{4}$ is the correct option.
