Answer:
Moses got into the elevator at the 8th floor.
Step-by-step explanation:
Let's call the floor which Moses started at x. Going down decreases the floor number and going up increases the floor number. We then form the equation 
which is the same as 
which means 
. Moses got in at the 8th floor.
triangle on right is the same as the triangle on the left
use pythagorean theorem
hypotenuse will give to the sides of the rectangle
a^2 + b^2 = hypotenuse squared
10.4^2 = 108.16
15.3^2 = 234.09
342.25 = hypotenuse squared
take the square root in both sides
hypotenuse = the square root of 342.25 =
18.5
add up the areas of the 2 triangles and rectangle
triangle area is 1/2 times 10.4 times 15.3 =
79.56
2 triangles areas are 159.12
rectangle area is 18.5 × 7 = 129.5
159.12 + 129.5 = 288.62
answer 1 = 288.62
second question:
to get 1 side take the
square root of 702.25 which is
26.5
to get the perimeter
multiply 26.5 by 4 which is
106
answer 2 is choice B 106
Answer:
B. (x, y) → (-x,-y)
This rule is given triangle is reflection about origin or
Rotation clockwise or counter clock wise with 180°
Step-by-step explanation:
<u>Explanation:-</u>
A triangle has coordinates at X(3,7),Y(6,7) and Z(4,2)
The Rule ( x, y)→ ( - x, -y)
<em>This rule is given triangle is reflection about origin or Rotation clockwise or counter clock wise with 180°</em>
X( 3,7) → X¹ ( -3,-7)
Y(6,7) → Y¹ (-6,-7)
Z(4,2) → Z¹( -4 ,-2)
Answer:
I going to go with B $2378.30
Answer:
X=10
Step-by-step explanation:
3x=30
3(10)=30
30=30
30+42=72
I hope this helps!
