Answer:
The sales tax rate of an item that costs $4 is 8%
Step-by-step explanation:
An item costs $4 before tax
The same item costs $4.32 after sales tax.
So the tax rate can be calculated as:
Tax rate = $4.32 - $4 = $0.32
Next, you must divide the tax rate by the original price in order to get the sales tax rate:
Sales tax rate = $0.32/4$ = 0.08
In percentage:
Sales tax rate % = 0.08x100% = 8%
Answer and Step-by-step explanation:
First work out the area of the semi circle so, To do this we find the area a circle and half it.
<em><u>We know that:</u></em>
→ The radius of the semi circle is 4.
→ To find the area of a circle is it radius² x π
→ Therefore the area of the semi circle is 4 ² x π
→ Then divide this by 2.
→ Then you should get 16 π which equals 50.26548246 cm ².
Now, to find the area of the triangle:
→ The area of a triangle is base x height divided by 2.
→ Therefore you should get 9 x 8 divided by 2 which you should get to 36 cm ².
→ Then add the two together to get:
86. 26548246.
→ Then round to the newest hundredth to get to the final answer of : <u>86.27cm².</u>

The <em><u>correct answer</u></em> is:
The degree of the polynomial is 4 and the maximum number of terms is 9.
Explanation:
Multiplying the terms of each trinomial that have the largest degree, we are multiplying x²(x²); this gives us x⁴. This means the degree of the trinomial, the largest degree of all terms, is 4.
Without multiplying through, we know we will multiply each term of the first trinomial by each term of the second one. This means that, if no terms are like to combine, we could have 3(3) = 9 terms.
