Answer:
1286, I think
Step-by-step explanation:
Answer:
a). 240 miles (Approx)
b). Trip can't be covered in 3 hours with a constant speed = 70 miles pr hour
Step-by-step explanation:
a). As the scale has been given at the bottom. Length of the scale represents the distance between two points.
Now by measuring the distance between these stations, approximate distance between Amarillo and Oklahoma = 4(length of the scale)
= 4×60
= 240 miles.
b). Driving at a constant speed = 70 miles per hour
Distance covered in 3 hours = 70 × 3
= 210 miles
Therefore, distance of 240 miles between these stations can't be covered with the driving speed 70 miles per hour in 3 hours.
Answer:
if the height is h and the base is 2b
then we have:
½(2bh)=60→2bh=120
b²+h²=13²=169
so
(b+h)²=b²+h²+2bh=120+169=289
(b-h)²=b²+h²-2bh=169-120=49
so
b+h=17
|b-h|=7
so b can be 12 and h can be 5
or b can be 5 and h can be 12
which means the base is either 24cm or 10cm
