Givens

a1 = -70

d = -10

an = - 100

Formula

an = a1 + (n - 1)*d

Solution

-100 = -70 + (n - 1)*-10 Remove the brackets.

-100 = - 70 + -10n + 10 Combine

-100 = -60 - 10n Add 60 to both sides

-100+60 = -60+60 - 10n Combine

-40 = - 10n Divide by - 10

-40/-10 = n

n = 4

Emily measures 3 pieces of string with the first piece measures 642 cm the second piece measures 124 cm and the third piece is 1

NeX [460]

Answer: the total length of the string is 9 meters.

Step-by-step explanation:

The total number of strings that Emily measured is 3.

The length of the first piece of string measures 642 cm.

The length of the second piece of string measures 124 cm.

The length of the third piece of string measures 134 cm.

Therefore, the total length of the 3 pieces of string would be

642 + 124 + 134 = 900 cm.

100 cm = 1 m,

Converting 900 centimeters to meters, it becomes

900/1100 = 9 meters

1 1/3 miles in 1/4 hours

Romashka [77]

Answer:

So even though it'll be a little strange, you do just take the miles and divide by the hours. Since 1 1/3 is the same as 4/3 then the rate = (4/3)/(1/4).

That's the same as 4/3 * 4 = 16/3 miles per hour. Or 5 1/3 miles per hour.
