4. original = 12 degrees
Rose by 8 degrees
12+8= 20
drop by 28 degrees
20-28= -8 degrees.
So the answer is -8°.

5. (-6) * (-4) = 24

when a negative times a negative, the result will turn positive.

6. I believe it's a divide sign, ➗
-63 / -7 = 9
when a negative divides by a negative, the result turns positive.

But if it's a positive sign, than it's -70.
-63 + -7= -70

Step-by-step explanation:

As per the statement:

There are 486 hamsters at a private showing of a new documentary about humans.

⇒Total number of hamsters = 486

It is also given that there are 12 seats in each row.

They will fill = $\frac{486}{12} = 40.5$

Therefore, the best estimate the rows will hamsters fill is 40 rows.

What is an algebraic expression for "41 more than y "?

iren2701 [21]

All you have to do is add the number to the variable you need to. It works the same for subtraction instead you will put y-14 or any variable and number that is needed to subtract from it and remember when they say a number more than a variable it is + that number if they say a number less than a variable it is - that number .

y+14

What is the hypotenuse of a right triangle if the legs are each 20 inches long? Round to the nearest whole number. A. 28 B. 29 C

marusya05 [52]

Answer:

The answer is A.

Step-by-step explanation:

You have to apply Pythagoras Theorem :

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

$let \: a = 20,b = 20$

${c}^{2} = {20}^{2} + {20}^{2}$

${c}^{2} = 800$

$c = \sqrt{800}$

$c = 28 \: (nearest \: whole \: no.)$

P.S (Take note):

Pythagoras Theorem can only applied in right angle triangle.

Please help i have no clue how to do this. any tips please and thank you :)

circumference= 2(pi)r OR (pi)d
d is diameter and r is radius

if the circumference is given, then you would have to work backwards.

in this case, Circumference = 78.5 ft

the equal you would use for the radius would be 78.5 = 2 x 3.14(pi) x r
- multiply 2 x 3.14 and get 6.28
- divide 6.28 on both sides to get ‘r’ by itself
- 12.5 = r

next, for the diameter you can use C= (pi) x d
- 78.5 = 3.14 x D
- divide 3.14 on both sides to get ‘d’ by itself
- 25 = d

hope this helps! make brainliest please
