The correct question is
<span>Brett made a scale drawing of a rectangular room in his house. The actual length of the room is 12 4/5 ft. The scale used to make the drawing was 1/4 in.=1 ft. What is the length, in inches, of the room on the drawing?</span>
we know that
scale=measure in the drawing/measure in the actual
measure in the drawing=measure in the actual*scale
in this problem
scale=1/4 in/ 1 ft-----> 1/4
measure in the actual=12 4/5 ft-----> (12*5+4)/5----> 64/5 ft
so
measure in the drawing=(64/5)*(1/4)----> 3.2 in
the answer is
the length, in inches, of the room on the drawing is 3.2
42 ft^2
Subtracting ‘blank’ space from a larger figure:
(5*12) - (6*3) = 42
60 - 18 = 42
5*12 = 60
6*3 = 18
Breaking down the figure into smaller figures:
(12*2) + (3*3) + (3*3) = 42
12*2 = 24
3*3 = 9
3*3 = 9
Answer:
-18, <u>-20</u>, <u>-22</u>, -24
Step-by-step explanation:
The pattern is -2 or adding -2 each time. -18 -2 is -20. -20 -2 is -22. -22 -2 is -24.

Answer:
heart rate during exercise become 126 bpm
Step-by-step explanation:
maximum benefit is when heart beat increased by 50%-85%
alice resting heart rate= 70 bpm
increased heart rate of alice = 80%
increased heart rate =
total heart rate = 70+56=126 bpm
so, the heart rate of alice during exercise become 126 bpm
