I think it is A. Because it says that 1/3 is dividing the difference of 15 and an number, furthermore "one third" mean divide by 3.

Correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.
klasskru [66]
F(x)=25-x^2
g(x)=x+5

f/g(x)=(25-x^2)/(x+5)

f(x) is in binomial form so 25-x^2 can also be written as (5-x)(5+x)

so

f/g(x)=(5-x)(5+x)/(x+5)
f/g(x)=5-x

Given that a=16cm and b=17cm work out the height of the triangle
lilavasa [31]

Answer:

√33 cm

Step-by-step explanation:

Here,

b² = a² + c²

Because it is a right triangle

=> (17)² = (16)² + c²

=> 289 = 256 + c²

=> 289 - 256 = c²

=> 33 = c²

=> √33 = c

Hence,

height of triangle is √33 cm

David, Ben, and Jordan shared stickers in a ratio of 8 : 9 : 10. If Ben had 36 stickers, how many stickers did Jordan have?
pantera1 [17]

Answer:

Jordan had 40 stickers.

Step-by-step explanation:

For this ratio, we have David:Ben:Jordan as 8:9:10, and so we need to make it as a more complex fraction, 8/9/10, now we need a multiplier to get us from 9 stickers of Jordan to 36, like a giant one. The common multiplier in this case is 4, and we know that the values must always stay proportional. We multiply everything by 4,and we get a final ratio of 32:36:40, and since Jordan is the last in the ratio David:Ben:Jordan, Jordan ends up with 40 stickers.
