Answer:
x+20
Step-by-step explanation:
As we can see n the diagram, there are parallel traversals and one line, and the two angles given are same-side interior angles. We know that when there is parallel traversal, and we have same side interiors, the sum of the measure of the two angles are supplementary. Supplementary means 180 degrees, or a straight line.
So we plug everything in and we have 4x+5x=180 degrees
4x+5x=9x, so 9x=180
We divide by 9 on both sides to get the value of x, which is 20
Hope it helps!
Answer:
The clock face is divided into sixty equal parts, each minute. The minute hand is located on the 20 minute mark at 6:20, the hour hand located between the 30 minute mark and the 35 minute mark. When the minute hand goes all sixty minutes, the hour hand only moves five, so to figure out the location of the hour hand, we look at how much the hour has progressed, in this case 20 minutes, or one third of the hour. So the minute hand has moved one third of the way through the hour, so has the hour hand moved one third of the way through the five minutes, or, five thirds of a minute, which is one and two thirds minute, one minute forty seconds. That puts the hour hand at thirty minutes plus one minute and forty seconds—at 31min 40sec—which is 11min 40sec farther than the minute hand.

Answer:
Mean =13, Median=9, Mode =7, Range=43
Step-by-step explanation:
(1)Mean
<u>Median</u>
First we arrange the sales in ascending order
7,7,7,8,9,9,10,11,12,50
Since there are two terms in the middle, the Median =(9+9)/2 =9
<u>Mode</u>
The mode is the number of sales with the highest frequency.
Mode =7
<u>Range</u>
Range =Highest Value - Lowest value =50-7=43
(b)Mean =13, Median=9, Mode =7, Range=43
The Median seems to best represent the ten numbers. this is as a result of the fact that the value of the Mean and range were affected by the outlier number(50).
The School should therefore order T-Shirts in the range of the Median.
