Answer:
8.84 ×10⁻¹
Step-by-step explanation:
Move one decimal to the right to make one number go after the decimal. (ONLY one number from 0 - 9)
0.884 to 08.84
Now with how many times the decimal moves, it determines the power. Left equals positive and right is negative.
Standard form goes with × 10ˣ
the x next to 10 is the power.
The decimal moved 1 right so the power would be -1.
So,
8.84 × 10⁻¹
Answer:
-1y or -y
Step-by-step explanation:
8-9 =-1
substtute for y and there ya go
Answer:
104.8 in^2
Step-by-step explanation:
There are 2 ways to solve this problem.
The 1st way:
Let's make 2 triangles and 1 rectangle:
Rectangle Length = 8.3
Rectangle Width = 8
So, the left out length will be 17.9 - 8.3
=> 9.6
Since, 9.6 cm is for 2 parts.
=> 9.6 / 2
=> 4.8
So, Height of the Triangle = 8
Base of the triangle = 4.8
Area of a rectangle
=> 8.3 x 8
=> 66.4
Area of the triangle
=> 1/2 x 8 x 4.8
=> 4 x 4.8
=> 19.2
There are 2 triangles:
=> 19.2 x 2
=> 38.4
=> 66.4 + 38.4
=> 104.8
The area of the trapezoid = 104.8 in^2.
The 2nd way is:
Area of a trapezoid
=> Smaller Base + Larger Base / 2 x Height
=> 8.3 + 17.9 / 2 x 8
=> 26.2 / 2 x 8
=> 13.1 x 8
=> 104.8
The area of the trapezoid is 104.8 in^2
2 hours because 65 miles is = to one hour
130=65x2
130 miles is =to 2 hours
