Answer:
7.5 sqft.
Step-by-step explanation:
70.8/9.44=7.5
7.5x9.44=70.8
7.5 is the height.
We know that
surface area=area of the base+4*[area of one lateral triangle side]
area of the base=b²
b is the side length of the square
b=14 cm
area of the base=14²-----> 196 cm²
area of one lateral triangle side=b*h/2
b is the side length of the square
b=14 cm
h is the height of the lateral triangle side
h is equal to the slant height
h=15 cm
area of one lateral triangle side=14*15/2----> 105 cm²
surface area=196+4*[105]------> 616 cm²
the answer is
the surface area is 616 cm²
Hey there!
We know that perimeter is all the sides added up.
70= 2w+2L <== this is the basic equation
We know that the rectangles length is three times as long as it is wide.
So, you know that is is three times the length of the width. So, put 3 times w in as length and times that by two since there are two length sides, and keep width the same. 2w because there are two width sides. Then, solve.
70=2(3w)+2w
70= 6w+2w
70=8w
w=8.75
We can check this by plugging it in to our first equation and seeing if it works. First, we need to multiply 8.75 by 3 to get the value for length.
8.75*3= 26.25
2(26.25)+2(8.75)= 70 <=== it works!
So, the length is 26.25 cm and the width is 8.75 cm.
I hope this helps!

Answer:
Ty covered the least distance per min.
Step-by-step explanation:
Who covered the shortest distance per minute, or who rode his bike most slowly?
Andre's rate: (750 m) / (3 min) = 250/3 m/min
Rick's rate: (800 m) / (4 min) = 200 m/min
Ty's rate: (950 m) / (5 min) = 190 m/min
Ty was the rider who covered the least distance per minute; his rate was the slowest.
Answer:
7.2 units
Step-by-step explanation:
Distance² = (Change in y)² + (Change in x)²
Distance² = (4 - -5)² + (-3 - -7)²
Distance² = 36 + 16
Distance² = 52
Distance = 7.211102551
Rounding off the answer to nearest tenth gives 7.2 units
