Answer:
x+6 ≥ 25
Step-by-step explanation:
The product means the sum of <em>x</em> + 6. In this question, <em>x</em> + 6, is greater than or equal to the number 25 which is what ≥ means. Meaning, <em>x</em> can be replaced by a number that when added to <em>6</em>, <u>will equal to </u><u><em>25</em></u><u> or more</u>. For example, <em>x </em>can equal <em>19, 20, 21 </em>and so on.
Answer:
12
Step-by-step explanation:
There are 4 different digits to choose from. Since we want 2-digit number, we will see what digits can we put in place of 1st digit and what digit can we place in place of 2nd digit.
Hence, <u><em>how many digits (from 1,5,6 and 8) can be placed in the 1st digit of the number we want?</em></u>
Any one of the four digits (1,5,6, or 8).
Now, <em><u>How many digits (from 1,5,6 and 8) can be placed as the 2nd digit of the number we want?</u></em>
Any one of the THREE digits (since repetition is not allowed, we disregard the initial digit).
Thus the number of two-digit positive integers is 4 * 3 = 12
154/22 sales = $7/sale
<span>$7/sale(35 sales) = $245 </span>
<span>He will earn $245 for 35 sales.</span>
Considering that the shaded area is the part of the semi circle outside the triangle:
Area of circle= Pi x radius2 (this means radius squared)
Area of triangle= 1/2 x base x height
1/2 (because it is a semi circle) x 3.14 (in replacement of pi as directed by question) x 9squared= 127.17
127.17 - (1/2 x 18 x 9) = 46.17cmsquared
