70 miles = 1 hour
Divide by 70 through to get 1 mile ..
(70 ÷ 70) miles = (1 ÷ 70) hour
1 mile = 1/70 hour
Multiply by 400 through to get 400 miles
1 x 400 miles = 1/70 x 400 hours
400 miles = 5 5/7 hours
Answer:
15.9
Step-by-step explanation:
so -9.7 is 9.7 jumps form 0 and same for 6.2 is 6.2 jumps from 0
9.7 + 6.2 = 15.9
the distance between -9.7 and 6.2 is 15.9
If we were to fold this into a prism, the rectangle on the left would be the base. The short sides of the triangles would fold to meet up with the 5 inch sides of the base. Then the rectangle on the right would fold down and fit between the two triangles, meeting up with the base. Visualizing the shape in 3 dimensions allows us to figure out the lengths of some sides. For example, the short sides of the triangles both equal 5 inches. Also, the long sides of the triangles equal 13 inches and the long side of the base is 8 inches.
The surface area is the area of all the surfaces.
8*5=40
8*12=96
2*(0.5*5*12)=60
13*8=104
Add these up..
40+96+60+104=300 in^2
Answer:
Step-by-step explanation:
If the complex number is a root of a cubic function, then the complex number is a root too. Thus, the cubic function has three known roots and can be written as
