1. Pick two points on the line and determine their coordinates.

2. Determine the difference in y-coordinates of these two points (rise).

3. Determine the difference in x-coordinates for these two points (run).

4. Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

A pet store has 150 goldfish and betta fish altogether. The ratio of goldfish to betta fish is 2:3. How many goldfish does the p
Kipish [7]

The number of goldfish in the pet store is equal to 60 fishes.

  • Let the goldfish be G.
  • Let the betta fish be B.

<u>Given the following data:</u>

  • Total number of fishes = 150 fishes.
  • Ratio of G to B = 2:3
  • Total ratio= 2 + 3 = 5

To calculate the number of goldfish that the pet store have:

<h3>What is ratio?</h3>

Ratio can be defined as an expression that is used to denote the proportion of two (2) or more quantities with respect to one another and the total quantities.

Mathematically, the number of goldfish in the pet store is given by this expression:

G = \frac{2}{5} \times 150\\\\G=0.4 \times 150

G = 60 fishes.

A textbook store sold a combined total of 477 sociology and math textbooks in a week. The number of sociology textbois sold was
denpristay [2]

Answer:

The correct answer is 218 math textbooks and 259 sociology textbooks.

Step-by-step explanation:

To solve this problem, we can make a system of equations. Let the number of sociology textbooks sold be represented by the variable "s" and the number of math textbooks sold be represented by the variable "m". Using these variables, we can make two equations:

s + m = 477

m + 41 = s

There are many ways to solve this system of equations. One approach we can take is substituting the value for s given by the second equation into the first equation. This is modeled below.

s + m = 477

(m + 41) + m = 477

Combining like terms on the left side of the equation yields:

2m + 41 = 477

Subtracting 41 from both sides of the equation gives us:

2m = 436

Finally, dividing both sides of the equation by 2 gives us:

m = 218

To solve for the number of sociology textbooks, we can substitute into either of our original equations.

m + 41 = s

(218) + 41 = s

s = 259

Therefore, your answer is m = 218 and s = 259, or 218 math textbooks and 259 sociology textbooks were sold.

Hope this helps!

Answer:

Answer Below

Step-by-step explanation:

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

You can also search "how to find the volume of a triangular prism" and there will be a base calculator so u can figure out this problem!
