<span>Seth travelled 1 mile in 57.1 seconds. Now, I hour = 60 minutes and 1 minute = 6-0 seconds. Thus, 1 hour = 3600 seconds. Thus, 1 mile/57.1 seconds = (1 mile/ 57.1 seconds)(3600 seconds/1 hour) = (3600/57.1) mile/hour ≈ 63.047 mile/hour.</span>
Scale factor is given by:
(length of larger figure)/(length of smaller figure)=(width of larger figure)/(width of the smaller figure)=3.4
The length of the larger figure will be given by:
length=(scale factor)*(length of smaller figure)
=3.4*6=20.4 cm
width of the larger figure will be given by:
width=(scale factor)*(width of smaller figure)
=3.4*4.5
=15.3 cm
Therefore the dimension of the new parallelogram will be 20.4 cm by 15.3 cm
Answer:
9, 40 and 41
Step-by-step explanation:
All right triangle have lengths that follow the Pythagorean Theorem (a²+b² = c²). Right triangles have one angle equal to 90°. The two shorter sides form the right angle and the side opposite the right angle is called the hypotenuse.
Using the lengths given, we can use guess and check to see what sum of two sides squared would equal a third side, or just plug them into the equation: a²+b² = c² and see what lengths fit this equation.
I recommend starting with squares you are familiar with:
9² + 40²= 81 + 1600 = 1681
Now, take the √1681 to find the length of 'c', or the hypotenuse:
√1681 = 41
Since these three lengths fit the Pythagorean Theoreom, the would form a right triangle.
38 = 5y - 1
39 = 5y
39/5 = y
7.8 = y
or 7 4/5 = y or y = 7 4/5
hope this helps :)
