Answer: About 3
Step-by-step explanation:
Given : A lawn is in the shape of a trapezoid with following dimensions :-
Height : h = 50 feet
Bases : a = 30 feet and b=170 feet
Area of trapezoid is given by :-
Also , it is given that each bag covers 2400 square feet.
Then, the number of bags of fertilizer needed =
Hence, about 3 bags of fertilizer must be purchased to cover the lawn.
Answer:
Step-by-step explanation:
9(x + 1) = 25 + x
9x + 9 = 25 + x
Bringing like terms on one side
9x - x = 25 - 9
8x = 16
x = 16/8 = 2
Answer:
(1, 0.5)
Step-by-step explanation:
From the graph attached,
x-values are representing the number of games downloaded,
y - values are representing the total cost.
Unit rate means rate of 1 game downloaded.
If we represent this in terms of coordinates,
x- value (game downloaded) = 1
y - value (price of one game download) = $0.5
Therefore, point (1, 0.5) will represent the unit rate.
Option (2) on the top row will be the answer.
42 x 28 = (40 + 2) x (20 + 8) = 40 x 20 + 40 x 8 + 2 x 20 + 2 x 8
= 800 + 320 + 40 + 16
Answer:
B. [144, 174]
Step-by-step explanation:
Given
Total Weight Range = Not less than 145lb and Not more than 175lb
Required
Determine the actual weight range
Let x represent the total possible weight of a bodybuilder
From the question, we understand that the total weight is within the range of 145 to 175. i.e.
Also from the question, we understand that the bodybuilder's cloth adds 1 lb to the total weight;
The next step is to subtract this 1 lb from the range of total weight to get the actual weight range
This is as follows
This gives
<em>From the list of given options, the correct answer is [144,174]</em>
