one leg of an isoceles right triangle measures 5 inches. round to the nearest tenth, what is the approximate length of the hypot

sergeinik [125]

Because we know the leg with the measure is not the hypotenuse, the two legs would be 5 inches each. Using the Pythagorean Theorem, 5^2 + 5^2 = C^2, when C is the length of the hypotenuse. 5^2 is 25, so 25 + 25 = 50. We need to find the square root of 50, and the closest number is 7.07 or 7.1.

Morris has 2 3/4 gallons of ice tea. He gives 3/7 of it to her friend. How many gallons of ice tea does Morris have left?

lara31 [8.8K]

Answer:

$2 \frac{9}{28}$ gallons of ice tea is left with Morris

Step-by-step explanation:

Morris has 2 3/4 gallons of ice tea. He gives 3/7 of it to her friend.

Morris has 2 3/4 gallons of ice tea

$2\frac{3}{4}= \frac{2*4+3}{4}=\frac{11}{4}$

He gives 3/7 of it to her friend.

To find how many gallons of ice tea does Morris have left , we subtract 3/7 from 11/4

$\frac{11}{4}- \frac{3}{7}$

Make the denominators same

$\frac{11*7}{4*7}- \frac{3*4}{7*4}$

$\frac{77}{28}- \frac{12}{28}$

$\frac{65}{28}$

$\frac{65}{28} = 2 \frac{9}{28}$

In an effort to control vegetation overgrowth, 114 rabbits are released in an isolated area free of predators. After 3 years, it

valentina_108 [34]

114 rabbits are released in an isolated area free of predators

When month =0 , the rabbits = 114

3 years = 36 months

When months = 36 , then rabbits = 912

(0,144) and (36, 912)

Exponential growth equation is y = ab^x

Plug in each point and solve for 'a' and 'b'

$114= ab^0$ so a= 114

(36, 912)

$912= 114b^{36}$

Divide both sides by 114 and then take 36th root on both sides

8 = b^36

b = 1.05946

so exponential equation is $y= 114(1.05946)^x$

x is the number of months and y is the population

to find the population be after another 3 months

Plug in 36+3= 39 for x and find out y

$y= 114(1.05946)^{39}$

y= 1084.43336

so , 1084 rabbits after another 3 months
