Mathematics
1 answer:
alexandr402 [8]3 years ago
5 0

Answer:

x = 8.5

Step-by-step explanation:

I got this answer by assuming the triangles were congurent, if they are not, the answer may vary.  

first, make an equation:

x + 8 = 3x - 9

bring 3x to the other side, by subtracting it

-2x + 8 = -9

Subtract 8

-2x = -17

divide by -2

x = 8.5

Then, just sub x into the formulas

Please help me with this problem.
mariarad [96]

Answer:

x^{\frac{8}{3}}y^{-\frac{5}{6}

Step-by-step explanation:

Remember the rule for converting radicals and exponents into fractions.  The power is the numerator of the fraction, and the nth root is the denominator of the fraction.  Also, remember that dividing by an exponent means the exponent will be negative.

\frac{\sqrt[3]{x^{8} } }{\sqrt[6]{y^{5} } } \\\\\frac{x^{\frac{8}{3} } }{y^{\frac{5}{6} } } \\\\x^{\frac{8}{3}}y^{-\frac{5}{6}

There are 20 alligators in the swamp. Each year, the number of alligators increases by 25%. There are 25 crocodiles in the swamp
Vera_Pavlovna [14]

Answer:

Step-by-step explanation:

We have given that:

There are 20 alligators in the swamp. Each year, the number of alligators increases by 25%. There are 25 crocodiles in the swamp. Each year, 10 new crocodiles join the swamp

Part A:

According to the above mentioned statement the function for representing the number of alligators and crocodiles in the swap throughout the year is:

Alligators = y=20(1.25)^x (x represents years)

crocodiles: y=10x+25

Part B:

Number of alligators after 4 years in the swap = y=20(1.25)^x

Number of alligators after 4 years in the swap = y=20(1.25)^4

Number of alligators after 4 years in the swap=48.82

This shows that about 48 to 49 alligators will be there in the swap after 4 year

Number of crocodiles after 4 years in the swap = y= 10(4)+25 = 65

Part C:

We will use the graph method to solve this part:

After approximately 7 years, the number of animals of each type will be the same, 95.
