Answer: 2,000
Step-by-step explanation:it’s 2,000 because the 7 is in the thousand place and 7 minus 5 = 2.
She can by at least 18 shirts. An equation would be 5.75•18+1.5=105
Answer:
4,896
Step-by-step explanation: there is only 18 possible ways to win president, 17 ways to win vice president and 16 ways to win treasurer so you take 18x17x16=4,896
Answer:
$20.60
Step-by-step explanation:
Price before discount = $21
Discount rate = 10% or 0.1
Discount in dollars = 0.1* 21 = $2.1
Price after discount = $21 -$2.1 = <em>$18.90</em>
If sales tax is 9% or 0.09
amount of tax will be = 0.09 * 18.90 = <em>$1.701</em>
Total price of the phone including taxes = Price before tax + tax amount;
Total price = 18.90 +1.701
= 20.601
Therefore total price will be $20.60
Answer:
<em>Area of Regular Polygon = ( About ) 332.6 units^2; Option C</em>
Step-by-step explanation:
<em>~ Let us first declare consecutive notes. If we were to draw an altitude in this triangle, it would be perpendicular to the base, by definition. At the same time this shape is a regular polygon, so all sides ( and angles ) are ≅. This would mean that, by Coincidence Theorem, the altitude divides the base into the two ≅ parts. ~</em>
1. If that is so, the altitude would split this base into parts ⇒ ( 16√3 )/2 = 8√3.
2. This would mean that the altitude can be found through Pythagorean Theorem, provided that by definition it forms a 90 degree angle at the base. Let us say x ⇒ the length of the altitude, ( 8√3 )^2 + ( x )^2 = ( 16√3 )^2 ⇒ 192 + x^2 = 768 ⇒ x^2 = 576 ⇒ length of altitude - 24 units
3. With the base 16√3 units, and the the altitude/height 24 units, we can find the area of this regular polygon to be ⇒ 1/2 * base * height ⇒ 1/2 * 16√3 * 24 ⇒ 192√3 units^2
4. That being said that area would be 192 * 1.732050808...... ⇒
<em>Area of Regular Polygon = ( About ) 332.6 units^2</em>
