The answer is 69. the angle is a right angle which means it is 90 degrees. subtract 90-21 to get 69
Answer:
its 4
Step-by-step explanation:
3<span>pink
5red
4yellow
12 total roses.
Probability of selecting a pink rose would be 3/12 or 1/4.
p(pink)=3/12=1/4
The complement of that would be 1-1/4=3/4.
P(NOT pink)=1-1/4=3/4
So theres a 3/4 chance that she WON'T randomly select a pink rose.
Answer=3/4</span>
<span>I rounded up the whole number as if each student sells only 3 sweatshirts, it is too little to pay for the whole trip, therefore the number must be 4. Hope that helps!</span>
So the first thing you want to do when faced with two fractions with different denominators (when subtracting or adding) is to make the denominators the same. So for this equation they would turn out to be p+10/16=15/16 (because 16 is the lowest common denominator, 8 times two) so then you want to subtract 10/16 from 15/16 to isolate the variable (p) which would get:
p=5/16
This is the final answer because it cannot be simplified.
Hope this helps!
