Two automobiles start together from the same place and travel along the same route. The first averages 40 miles
natita [175]

Answer:

A. (55 x 5) - (40 x 5)

Step-by-step explanation:

You are solving how much miles (further along) would the second car be after 5 hours.

The first car averages 40 miles per hour. 5 hours later, it will have averaged about 200 miles in 5 hours (40 x 5 = 200).

The second car averages 55 miles per hour. 5 hours later, it will have averaged about 275 miles in 5 hours (55 x 5 = 275)

Subtract: 275 - 200 = 75

The second car would have averaged 75 more miles than the first car.

How many sets of two or more consecutive positive integers can be added to obtain a sum of 1800?
Nataliya [291]

Answer:

n = 60

Step-by-step explanation:

GIVEN DATA:

Total sum of consecutive number is 1800

sum of n number is given as

sum = \frac{ n(n+1)}{2}

where n is positive number and belong to natural number i.e 1,2,3,4,...

from the data given we have1800 = \frac{n(n+1)}{2}

solving for n we get

[/tex]n^2 + n -3600 = 0[/tex]

n = 59.5, -60.5

therefore n = 60

From equations (1) & (2)

\angle ABC \cong \angle CAB\\\therefore AC = BC

(Because sides opposite to equal angles are equal)

Hence Proved
