48/3 = 16. On the second day she sold 16 notebooks.
16-2(she sold two more each day) = 14
16+2=18
Day 1=14
Day 2=16
Day 3=18
Answer:
3.1 seconds
Step-by-step explanation:
The time it will hit the ground is when the <em>height is equal to 0</em>. So we plug in 0 in h and solve the quadratic equation for t.
We will use the quadratic formula [
] to solve this.
a is -16
b is 40 , and
c is 30.
plugging these into the formula we get:
Since time cannot be negative, we take t = 3.1 as the value
So it will take 3.1 seconds to hit the ground (target)
Use the Rational Root Theorem, which gives all the possible values that are roots. From there, you can use either algebraic long division or synthetic division to figure out from the possible roots.
The given ratio for the measure of a pair of corresponding sides of similar polygon is also the same for all the sides. The perimeter, which is the sum of the measures of all the sides, will also have the same ratio. Thus, for the given above, the answer would be the third choice, 3/9 = 1/3.
Answer:
The answer is 0.55
Step-by-step explanation:
Because 55% = 
= 0.55
