1/3 of the fish in the tank are snappers. 2/9 of the fish are catfish and the rest are goldfish. There are 40 goldfish in the ta
Paraphin [41]

<u>Find fraction of snappers and catfish:</u>

1/3 + 2/9 = 3/9 + 2/9 = 5/9


<u>Find fraction of goldfish:</u>

1 - 5/9 = 4/9


4/9 = 40 goldfish

1/9 = 40 ÷ 4 = 10

9/9 = 10 x 9 = 90


Answer: 90 fish in the tank

Divide -2x^3-5x^2+4x+2 by x+2
erik [133]

<u>Answer</u><u>: </u>

The correct option is C.  -2x^2-x+6, R(-10)

<u> Explanation: </u>

<u>Given:</u>

Dividend = -2x^3-5x^2+4x+2

Divider =(x+2)

<u>Solution</u>:

Now by using the division method , we will find out the quotient and remainder of the given equation  

And the equation will become  

-2x^3-5x^2+4x+2=(x+2)(-2x^2-x+6)-10

So , We will get the quotient =-2x^2-x+6

And Remainder = -10

Hence the Correct option which perfectly satisfy the given equation is C.

Given the function f(x) = 0.65x + 117, what<br> s the x-value of the zero?
swat32

Answer:

x = -180

Step-by-step explanation:

0 = 0.65x + 117

-117 = 65x/100

cross-multiply to solve for 'x':

65x = -11700

x = -11700/65

x = -180

What is 1/10th of 2,871,000?
abruzzese [7]
This is fairly simple. Divide 2,871,000 by 10 and that's your answer!

\frac{2,871,000}{10} =287,100

Also, since you're dividing by a factor of 10 (or in this case, <em>10</em>) you can just take away as many places as are zeros in the number you're dividing from. This works for <em>10, 100, 1,000, 10,000, etc. </em>In this case, since there is only one zero in 10 you only take away one place marking, which gives you 287,100.

Answer:

option 4.

16 square units

Step-by-step explanation:

as we do not have the measures of the sides, but if the points of the vertices with Pythagoras we can calculate the sides.

P = (2 , 4)

S = (4 , 2)

we have to subtract the values ​​of p from s

PS = (4 - 2  , 2 - 4)

PS = (2 , -2)

by pitagoras h ^ 2 = c1 ^ 2 + c2 ^ 2

h: hypotenuse

c1: leg 1

c2: leg 2

PS^2 = 2^2 + -2^2

PS = √ 4 + 4

PS = √8

PS = 2√2

S = (4 , 2)

R = (8 , 6)

SR = (8-4  ,  6-2)

SR = (4 , 4)

by pitagoras h ^ 2 = c1 ^ 2 + c2 ^ 2

h: hypotenuse

c1: leg 1

c2: leg 2

SR^2 = 4^2 + 4^2

SR = √ (16 + 16)

SR = √32

SR = 4√2

having the values ​​of 2 of its sides we multiply them and obtain their area

PS * RS = Area

2√2 * 4√2 =

16
