Dear
A distance of one international mile or 1 760 international yards or exactly 1609.344 meters travelled in one hour or exactly 3 600 seconds. 1 Mile per hour = 1.60934 kilometers per hour = 0.44704 meters per second (SI base unit). 1 mph = 0.447 04 m/s.
Also,
1 Centimeter per second is equal to 0.01 meters per second (SI unit).
So, car travels 2235.2 cm per second.
Answer:
The slope is -2
Step-by-step explanation:
(−4,7);(2,−5)
(x1,y1)=(−4,7)
(x2,y2)=(2,−5)
m=
y2−y1
/x2−x1
−5−7
/2−4
−12
/6
−2
Answer:
A = 200ft²
Info:
l = 2w
P=2[(2w)+w)
P = 60
A=w(2w)
Step-by-step explanation:
Since we know the value of the perimeter, it's actually easy to solve with the information listed above.
Firstly, since the equation has the same variable, you can actually add them or multiply. You can write the perimeter in a new way,
P=6w
which means w =
,
or 10ft.
Now we know the width you can get the length by multiplying it by 2. Let's get the rectangle area.
A=w(2w) or A=wl
A=10(2x10) or A=10(20)
A = 200ft²
<u>Question Completion</u>
- Box A, The rectangular prism is of dimension 3 inch by 4 inch by 10 inch
- Box B, the Triangular prism has a base triangle of base 8 inch and height 3 inch. The length of the triangular prism is 6 Inch
See attached diagram
Answer:
Box B
Step-by-step explanation:
To determine the box which is made with less cardboard, we calculate the Total Surface Area of each box.
<u>Rectangular Prism(Box A)</u>
Total Surface Area=2(LW+LH+WH)
=2(10x4+10x3+3x4)
=
2(40+30+12)
=2(82)
Total Surface Area of Box A = 164 square inches
<u>Triangular Prism (Box B
)</u>
Total Surface Area=2(Area of Triangle)+Area of Base rectangle+2(Area of side rectangles)
=2(0.5X3X8)+(8X6)+2(5X6)
=24+48+60
=132
Total Surface Area of Box B = 132 square inches
Since the total surface area of Box b is lesser,Box B is made with less cardboard .
