Helen's house is located on a rectangular lot that is 1 1/8 miles by 9/10. Estimate the distance around the lot.

1 answer:

7 0

You round 1 1/8 to 1 and 9/10 to 1 (since you are estimating) and then you add 1+1+1+1, which is 4 because to find perimeter you add the lengths and the widths together.

PLS HELP ASAP PLEASE Heidi and Andrew designed two raised flower beds for their garden. Heidi's flower bed was 5 feet long by 3

Sidana [21]

First, find the area of both beds!
For Heidi: 5 x 3 = 15
For Andrew: 5 x (3 x 2) = 30 ft

Added together, the beds have an area of 45 feet. To place soil with a depth of 2 feet, simply multiply by 2. You can think of this as finding the volume of the beds, which is length x width x height, or area x height. The answer is 90 cubic feet!

Write the rule of the nth term of each sequence 7,4,1,-2

Zarrin [17]

Answer:

$a_{n}$ = 10 - 3n

Step-by-step explanation:

the terms 7, 4, 1, - 2 form an arithmetic sequence with n th term

$a_{n}$ = $a_{1}$ + (n - 1)d

where d is the common difference and $a_{1}$ the first term

here d = - 2 - 1 = 1 - 4 = 4 - 7 = - 3 and $a_{1}$ = 7, hence

$a_{n}$ = 7 - 3(n - 1) = 7 - 3n + 3 = 10 - 3n
