Answer:
37.66 Hours
Step-by-step explanation:
113÷ 3= 37.66
she watched it for 37.66 hours 1/3 times. each time she watched it for 37.66 hours and since she watched it 3 times it added to a total of 113 hours. hope this helped
Answer:
Step-by-step explanation:
Interesting bit of trivia if true.
The central Pacific Railway had a 24 month head start. Each month let them go 8.75 miles, so the total distance the rail went was 24*8;75 = 210 miles. They built this before the Union Pacific had done 1 mile of track.
So now when the Union Pacific started building, there remained 1590 - 210 miles of track to be laid. 1590 - 210 = 1380 miles of track.
The rest is pretty straight forward. Between the two rail companies, they built 28.75 miles of track a month.
Therefore the number of months = 1380/28.75 = 48 months.
The project took (in total) 48 + 24 = 72 months to build.
The Union Pacific built 48 * 20 = 960 miles of rail
The Central Pacific built 72 * 8.75 = 630 miles of rail
Total distance = 1590 miles which is the stated total.
Answers
Total Time = 72 months.
Union Pacific distance built = 960 miles
Central Pacific distance built = 630 miles
Non negative real numbers (y20)
Answer: Option B.
<u>Explanation:</u>
A non negative real number is a real number that that is either positive or zero. It's the association of the normal numbers and the number zero. In some cases it is alluded to as Z*, and it tends to be characterized as the as the set {0,1,2,3,… ,}. Z, the arrangement of whole numbers, is characterized as {… ,- 3,- 2,- 1,0,1,2,3,… }.
Since zero is commonly viewed as unsigned (neither positive nor negative) at that point, truly, it ought to be remembered for a lot of non-negative genuine numbers since it 'fits' the name. On the off chance that you needed to avoid zero, you could request the positive genuine numbers or the negative genuine numbers.
1/5(25-5a)=4-a
⇔5-a=4-a
NO SOLUTION
Length is 9meters and width is 3 meters
steps:
let's assume width of a rectangle = a meters
than length of the rectangle = 3*a= 3a
perimeter = 24 meters
formula to find perimeter: p = 2(l+w)
substitute the values of in the formula
24 = 2 (3a+a)
24 = 2(4a)
24 = 8a
24/8= a
3= a
a is width of the rectangle = 3 meters
length of the rectangle = 3* a = 3*3= 9 meters
hence and is length 9 meters and width 3 meters
