Answer: 16 total starbursts.
Step-by-step explanation:
If 25% were pink, then 75% aren't pink. Let x be the total number of starbursts. We know that 75% of x = 12 (the ones that aren't pink). There is insufficient information to determine whether there is even one red starburst.
0.75x = 12
x = 12/(3/4)
x = 48/3
x = 16
There are 16 total starbursts:
25% are pink = 4 pink starbursts
75% aren't pink = 12 non pink starbursts
Total of 16 starbursts.
We can't answer how many were red. We aren't given any indication that there is even one red starburst. All we know is that 12 are not pink.
7x^2 + 3
7(4)^2 + 3
7(16) + 3
112 + 3
115.
Answer:
The school needs 2,843 more to raise.
Step-by-step explanation:
Sonya is incorrect because 5000 minus 2157 is 2843.
The answer is 2843 more dollars.
The 2 sides of the right triangle is 25 and 24.
Any multiple of a Pythagorean triple is also considered a Pythagorean triple. Multiplying 3, 4, 5 by 2 gives 6, 8, 10, which is another triple. To see if a set of numbers makes a Pythagorean triple, plug them into the Pythagorean Theorem.
3,4,5 5,12,13 7,24,25 8,15,17 9,12,15
Final Result: 25,24
