In a right-angled triangle, the hypotenuse is 113 and a leg is 112.

melomori [17]

Answer: 15

Step-by-step explanation: Use the formula: $a^{2}+b^{2}=c^{2}$

Remember $c^{2}$ should always be the hypotenuse or the longest side.

$112^{2}+b^{2}=113^{2}$ ---> evaluate the exponents

$12544+b^{2}=12769$ ----> subtract 12544 to the other side

$b^{2}=225$ ---> take the square root of both sides

$b=15$

Answer:

BRIANLIEST PLZ

N = 18.75

M = 22.5

Step-by-step explanation:

Need the ratio of money paid to each. We know how the ratio of time is divided so we can use this ratio to find the amount paid.

T = t1 + t2 = 2.5 + 3 = 5.5

r1 =2.5/5.5

r2 = 3/5.5

Nick = r1 * 41.25 = 18.75

Monica = r2 * 41.25 = 22.5

Answer:

$P(x) = -0.25x^2 + 42x - 90$

Step-by-step explanation:

Given

$C(x) = -17x + 90$

$R(x) =- 0.25x^2 + 25x$

Required

Determine the profit function.

Profit function is calculated as thus:

$P(x) = R(x) - C(x)$

So, we have:

$P(x) = -0.25x^2 + 25x -(-17x + 90)$

$P(x) = -0.25x^2 + 25x + 17x - 90$

$P(x) = -0.25x^2 + 42x - 90$
