Solution:
we have been asked to find
Which of the given number words represents the numeral 4,056?
Its about the counting.
On unit place we have 6.
on Tenth place we have 5.
on hundredth place we have 0.
On Thousand place we have 4.
so in our number word representation there will be no "Hundreds".
So it will make
Hence the given number words representing the numeral 4,056 is Four thousands and fifty six
Answer:
Her speed on the summit was 35 mph.
Step-by-step explanation:
Her speed on the summit was "x" mph while her speed while climbing was "x - 10" mph. The distance she rode uphill was 55 miles and on the summit it was 28 miles. The total time she explored the mountain was 3 hours. Therefore:
time uphill = distance uphill / speed uphill = 55 / (x - 10)
time summit = distance summit / speed summit = 28 / x
total time = time uphill + time summit
3 = [55 / (x - 10)] + 28 / x
3 = [55*x + 28*(x - 10)]/[x*(x - 10)]
3*x*(x - 10) = 55*x + 28*x - 280
3x² - 30*x = 83*x - 280
3x² - 113*x + 280 = 0
x1 = {-(-113) + sqrt[(-113)² - 4*(3)*(280)]}/(2*3) = 35 mph
x2 = {-(-113) - sqrt[(-113)² - 4*(3)*(280)]}/(2*3) = 2.67 mph
Since her speed on the uphill couldn't be negative the speed on the summit can only be 35 mph.
Answer:
(-4, 2.5)
Step-by-step explanation:
-8/2=-4
5/2=2.5
X- smaller number
y- larger number
5x=6+y
(X)+2(x+1)=26
3x=24
X=8
Y=x+1
Y=8+1
Y=9
The two numbers are 8 and 9
