Answer:

Step-by-step explanation:

Use Pythagorean theorem

$a^2 +b^2 =c^2$

c= always hypotenuse/ longest side/ side across from right angle = 13

a= 5

$5^2+b^2=13^2$

$25+b^2=169$

Subtract 25 from 169

$b^2= 144$

Square root both sides

b= 12

--------

it's also a special triangle known as a 5, 12, 13 triangle

Jonathan is making his favorite pasta dish. He serves his mom 1/12 of the pot of pasta and his brother 1/6 of the pot. How much

Sauron [17]

Answer:

3/4 of the pot left.

Step-by-step explanation:

If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.

If y²-x=7, find the positive value of when x=9.

mina [271]

Answer:

y = + 4

Step-by-step explanation:

y² - x = 7 ← substitute x = 9 into the equation

y² - 9 = 7 ( add 9 to both sides )

y² = 16 ( take square root of both sides )

y = ± $\sqrt{16}$ = ± 4

the positive value of y when x = 9 is + 4

Intersection of Intervals

Given the intervals A,B,C,etc. The intersection of them all is the set of all values that are common to all the intervals.

We must find

$\{x | x > -5\} \bigcap \ \{x | x < 5\}$

which is the intersection between the intervals x > -5 and x < 5. The intersection represents all the numbers greater than -5 and less than 5. It can also be said The numbers between -5 and 5 (non inclusive), third option

How do you <br>convert 7/5 into a decimal and round to the nearest hundreth

Amanda [17]

7/5 is an improper fraction. we need to change it to a mixed number:
7/5 -> 1 2/5

now, we know that 1/5 is 0.2 so that means 2/5 must be 0.4. there also is a 1 so the answer is going to be 1.4

The answer (rounding to the 100th place) is 1.4
