Time difference between 10:53AM and 10:53PM same day = 12 hours. 
<span>Time difference between 10:53PM and 12 midnight (next day) = 1 hour 7 minutes. </span>
<span>Time difference between 12 midnight and 1:05 AM (next day) = 1 hour 5 minutes. </span>
<span>Time difference between 1:05 AM (next day) and 1:05 PM (next day) = 12 hours. </span>

<span>Time difference between 10:53 AM one day and 1:05 PM the next day = 26 hours 12 minutes. Half of that is 13 hours 6 minutes. </span>

<span>10:53 AM + 12 hours = 10:53 PM. </span>
<span>10:53PM + 1 hour 6 mins = 11:59 PM

</span>My phone rang midway between 10:53 AM one day and 1:05 PM the next day. It rang at 11:59 PM.

i hope this helps! :)

Which fraction is bigger 2/6 or 2/4
Rina8888 [55]
2/4 is the larger fraction. Think of a candy bar that is cut into 4 equal pieces. Now think of the same sized candy bar cut into 6 pieces. The candy bar that has been cut into sixths has more pieces but they are smaller pieces that the candy bar cut into fourths. **When comparing fractions, if the numerators are the same (like they are in this problem) look at the denominators. Whichever fraction has the greater number is actually going to be the smaller fraction (more pieces, but smaller pieces). If the denominators are the same, then the fraction that has the greater number in the numerator will be the larger fraction (more same-sized pieces than the other fraction) Hope that helps!

Bill wanted to try out different water craft he went 62 mikes downstream in a motor boat and 27 mikes down stream on a jest ski
valina [46]

Answer:

The speed on motorboat is 20 mph

Step-by-step explanation:

here, we want to find the speed on the motorboat

if he has a speed of x mph on the motor boat, his speed on the ski will be (x + 10) mph

The total hours is 4 hours

Mathematically; speed = distance/time

Time on ski is 27/x+ 10

Time on motor boat is 62/x

The addition of both is 4

Thus;

27/(x + 10) + 62/x = 4

27(x) + 62(x + 10) = 4(x)(x + 10)

27x + 62x + 620 = 4(x^2 + 10x)

89x + 620 = 4x^2 + 40x

4x^2 -49x-620 = 0

using the quadratic formula;

{-b ± √(b^2-4ac)}/2a

where a = 4, b = -49 and c = -620

= 49 ± √(-49)^2-4(4)(-620)/8

So we have

49+ 111/8 or 49-111/8

Speed cannot be negative

(49 + 111)/8

= 20 mph

To find proportion of the area under the normal curve between two Z scores that are both above the mean, it is necessary to exam
VikaD [51]

It is necessary to imagine the sum of the areas between each z-score and the average.

Given as the ratio of the area under the normal curve between two z-scores, both above average.

The  Z score accurately measures the number of standard deviations above or below the mean of the data points.

The formula for calculating the z-score is

z = (data points – mean) / (standard deviation).

It is also expressed as z = (x-μ) / σ.

  • A positive z-score indicates that the data points are above average.
  • A negative z-score indicates that the data points are below average.
  • A z-score close to 0 means that the data points are close to average.
  • The normal curve is symmetric with respect to the mean and needs to be investigated.

Therefore, to find the percentage of the area under the normal curve between two z-scores, both above the mean, you need to look at the sum of the areas between the z-score and the mean.

Please help asap!!!!
igor_vitrenko [27]

Answer:

m\widehat {MP} =46\degree

Step-by-step explanation:

By inscribed angle theorem:

m\angle MQP=\frac{1}{2} \times \widehat {MP}

23\degree =\frac{1}{2} \times m\widehat {MP}

23\degree \times 2= m\widehat {MP}

m\widehat {MP} =46\degree
