Answer:
8 13/24
Step-by-step explanation:
42 2/3= 42 16/24
34 1/8= 34 3/24
42 16/24- 34 3/24= 8 13/24
Answer:
The approximate area is A) 5.09cm²
Step-by-step explanation:
Area of a Circle = πr²
r = 1.8
Plug in our values
π(1.8cm²)
Evaluate the area of the entire circle
a = π(1.8cm²)
a = π(3.24cm)
a = 10.179cm²
Area of a sector, with the area of the circle of the sector being a = theta/360 * a
Evaluate the area of the sector
180/360*10.719cm²
0.5 * 10.179cm²
5.0895cm²
Round the value up
5.09cm²
Answer:
36.9 m
Step-by-step explanation:
h(t) = -4.9t² + 25t + 6
At t = 3:
h(3) = -4.9(3)² + 25(3) + 6
h(3) = -44.1 + 75 + 6
h(3) = 36.9
After 3 seconds, the ball will have a height of 36.9 meters.
Answer:
For inverse operations, it helps make solving equations easier. Say if you'd rather add than subtract, then you can do the inverse of a negative equation.
Inverse operations are also very helpful for linear equations.
To find the inverse of an equation, we change the plus sign to a negative sign. Then, we switch the first number and the answer.
Ex:
13 - 2 = 11 (now change plus to minus)
13 + 2 = 11 (not the answer yet)
Now we switch the first number with the answer!
11 + 2 = 13
Hope this helped, I tried to explain it easily.
