This is how you set up a percent of error proportion:
<u>Amount of error</u> <u>x(Unknown percent)</u>
Actual value = 100(Percents are out of hundreds)
So if you fill it in, it becomes <u>4</u> <u>x
</u> 80 =100
Cross multiply, 400= 80x.
Solve.
x=5 so percent error is 5%<u>
</u>
Answer:
<h3>A. Add 3 to both sides of the equation</h3>
Step-by-step explanation:
The inequality equation is not well written Let's say the equation is given as:
5x - 3 > 2
<em>The best first step in solving this equation is by removing - 3 from the left hand side of the equation since all we want to do is make x the subject of the formula:</em>
To remove the -3, <u>we will have to add 3 to both sides of the inequality </u>as shown:
5x - 3 + 3> 2 +3
5x + 0 > 5
5x > 5
To get x, we will then divide both sides by 5
5x/5 > 5/5
x > 1
hence the best first step according to the explanation above is to Add 3 to both sides of the equation. Option A is correct
Answer:
86cm³
Step-by-step explanation:
The area of the triangle is 1/2(b)(h)*2. The 1/2 and 2 cancel out as we’re doubling the small triangle to make the big triangle. Then you just multiply it times the length of the prism. So the formula ends up:
2.5*4.3*8=86cm³
Given:
The equation of a circle is:
To find:
Center and the circumference of the circle.
Solution:
The standard form of a circle is:
...(i)
Where, (h,k) is center and r is the radius.
We have,
...(ii)
On comparing (i) and (ii), we get
So, the center of the circle is (3,0) and the radius of the circle is 
.
Now, the circumference of the circle is:
Therefore, the circumference of the circle is about 35.5 units.
3. y=112 this takes a lot of process of elimination so ill save you the paragraphs of numbers
second row - k³⁰/k¹⁴ - k¹⁶
third row - 12 ⁴⁵⁻²³ - 12²²
hope this helps
