Scarlet has $85 to spend at the pet store. She is definitely buying a catfish for $12, a rainbowfish for $13, and a betta fish f
ikadub [295]

Subtract the total of the 3 fish she is buying from the amount of money she has:

85 - (12 + 13 + 14) = 85 - 39 = 46

She has $46 to spend on crabs.

Divide the amount she has to spend by the price on one crab:

46 / 8 = 5.75

Since it isn't a whole number you need to round down, since she cant buy 0.75 of a crab.

She has enough money to buy 5 crabs.

Find the area of a regular decagon with a 12.3 in, apothem and 8 in. sides.
EleoNora [17]

Answer:

C

Step-by-step explanation:

The area (A) of a regular decagon is

A = \frac{1}{2} perimeter × apothem

perimeter = 10 × 8 = 80 in, thus

A = 0.5 × 80 × 12.3 = 492 in² → D

An equation in the form ax2+bx+c=0 is solved by the quadratic formula. The solution to the equation is shown below.x=−7±√ "572"
jolli1 [7]

Answer:

B: a = 1, b= 7, c = -2

Step-by-step explanation:

<u>Quadratic Formula</u>

x=\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}\quad\textsf{when}\:ax^2+bx+c=0

Given:

x=\dfrac{-7\pm\sqrt{57}}{2}

Comparing the terms of the given x-value with those of the quadratic formula:

\dfrac{-b \pm \sqrt{b^2-4ac} }{2a}=\dfrac{-7\pm\sqrt{57}}{2}

Therefore:

  • 2a=2 \implies a=1
  • b = 7
  • b^2-4ac=57

Using the found values of a and b to solve for c:

\implies b^2-4ac=57

\implies (7)^2-4(1)c=57

\implies 49-4c=57

\implies -4c=57-49

\implies -4c=8

\implies c=-2

In summary:   a = 1,  b = 7,  c = -2

\implies x^2+7x-2=0

Therefore, <u>option B</u> is the correct solution.
