Step-by-step explanation:
<u>Solving in steps</u>
- 3| 4.5 - 2| - 5 |-1.5 -(- 3)| =
- 3 |2.5| -5 |-1.5 + 3| =
- 3*2.5 - 5|1.5| =
- 7.5 - 5*1.5 =
- 7.5 - 7.5=
- 0
Answer:
20
Step-by-step explanation:
100 + 60 = 160
There are 180 degrees in a triangle so we do 180-160 = 20
Answer:
Step-by-step explanation:
(x²+4)²-11(x²+4)+24=0
put x²+4=y
y²-11y+24=0
y²-3y-8y+24=0
y(y-3)-8(y-3)=0
(y-3)(y-8)=0
y=3,8
so x²+4=3
x²=-1=i²
x=±i
or x²+4=8
x²=4
x=±2
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
Answer:
Your answer is B or option 2.
Step-by-step explanation:
When doing scale factors, you will multiply. Always. To get from the original box to the second box, you will multiply by a scale factor of 5/8. An equation can model this. b=5/8a. (Let a = dimensions of original/blue box, let b = dimensions of second/green box).
Since you need to find the dimensions of the first/original box, you need to change b=5/8a to a= <em>[something]. </em>To do that, divide both sides by 5/8. You have b / 5/8 = a. The dimensions of the second box divided by the scale factor 5/8 is the dimensions of the first box. This also makes sense, because the green box looks smaller than the blue box. Hope I helped! This is a challenging subject to explain properly. ^_^"
