Answer:
The answer in pic
Step-by-step explanation:
We are given an item cost before tax = $3.
Sales tax on item = 4.4% of the actual cost.
We are given actual cost = $3.
Therefore, 4.4 % of 3 = 0.044 × 3 = $0.132.
We need to round it to the nearest hundredth or cent that is upto two decimal places.
0.132 could be round to 0.13.
<h3>Therefore, $0.13 tax would you pay on that item on the given item cost $3.</h3>
Hello!
An equivalent fraction is a fraction that is equal to another but is just written different. For example 1/2 and 3/6. They are both one half of the whole. 3/6 is just put into smaller pieces, but they equal the same thing.
I hope this helps!
Question:
What is the area of the sector? Either enter an exact answer in terms of π or use 3.14 and enter your answer as a decimal rounded to the nearest hundredth.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the values of radius and central angle are not given.
However, I'll answer the question using the attached figure.
From the attached figure, the radius is 3 unit and the central angle is 120 degrees
The area of a sector is calculated as thus;
Where represents the central angle and r represents the radius
By substituting and r = 3
becomes
square units
Solving further to leave answer as a decimal; we have to substitute 3.14 for
So, becomes
square units
Hence, the area of the sector in the attached figure is or 9.42 square units
Answer:
x= -1, -9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/4x2+5/2x+21/4=3
Step 2: Subtract 3 from both sides.
1/4x2+5/2x+21/4−3=3−3
1/4x2+5/2x+9/4=0
For this equation: a=0.25, b=2.5, c=2.25
0.25x2+2.5x+2.25=0
Step 3: Use quadratic formula with a=0.25, b=2.5, c=2.25.
x=−b±√b2−4ac/2a
x=−(2.5)±√(2.5)2−4(0.25)(2.25)/2(0.25)
x=−2.5±√4/0.5
x=−1,−9
