Answer:

m=80.840 kg

Step-by-step explanation:

Given Data,

Q=23000 J

c=4.184 J/g °c

Δt= 68 °c

m=?

By using this equation,

Q=mcΔt

23000=m\times 4.184\times 68\\\\m=\frac{23000}{4.184\times68} \\\\\\m=80.840 kg

The number of fish (f) in a fish tank increases when the number of algae blooms (a) decreases. Write the correct equation for th
Artyom0805 [142]

Answer:

  • f = -2/5a +14
  • 12.4 ≈ 12 fish for 4 algae blooms

Step-by-step explanation:

The 2-point form of the equation for a line is useful when you are given two points to work with:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

The independent variable (x) is apparently "algae blooms" and is to be represented by "a". The dependent variable (y) is "number of fish" and is to be represented by "f". So, we have ...

  f = (4 -10)/(25 -10)(a -10) +10

  f = -6/15(a -10) +10

  f = -2/5a +14 . . . an equation for the scenario

Four a=4, the fish population is predicted to be ...

  f = -2/5(4) +14 = 12.4

There will be about 12 fish when there are 4 algae blooms.

Natalka [10]
175000 / 100 = 1750  this step finds 1% of 175000
1750 x 4.5 = 7875  this step finds 4.5% of 175000
Commission for first house $7875
199000 / 100 = 1990  this step finds 1% of 199000
1990 x 4.5 = 8955  this step finds 4.5% of 199000
Commission for second house $8955
$7875 + $8955 = $16,830

Kensho's commission for this quarter is $16,830
