Cool Down: Fish Population

Mathematics
1 answer:
Ber [7]3 years ago
5 0

Answer:

the population this year is 15 I think

Step-by-step explanation:

the population this year is 15 I think because 60 = 100% so if you divide 60 into two you will get 30 / 50%. then divide 30 again which would be 15 and that's 25 percent.  only if you know what 60 divides by 2 and then 30 divided by 2.

How do I solve this?<br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20%20%3E%20%20%5Cfrac%7Bt%20-%204%7D%7B%20-%2

First you’d separate into 2 inequalities so it would change to t-4/-3>-2 then you’d solve it for inequalities t-4/-3>-2 then you’d find the intersection which would be the answer: T (3,10)

6 + 3(x+4)<br><br> PLEASEEE I NEED HELP
Ksivusya [100]

i'm going to assume you're supposed to solve for x

Answer:

x = -2

Step-by-step explanation:

so you're trying to get x out of the equation and by it self

i would start this off by setting the equation equal to 0

then subtract 6

i would then divide by 3 on each side

you should then have x+4=2

you then subtract 4 to cancel it out

you then get your answer of x = -2

hope this helps and lmk if you have questions!! <3

On a coordinate plane, parallelogram R S T U is shown. Point R is at (1, 1), point S is at (7, 0), point T is at (10, 4), and po
ira [324]

Answer:

B,5.4 units.

Step-by-step explanation:

Parallelogram RSTU

R(1,1),S(7,0),T(10,4),U(4,5)

slope of RU m=(5-1)/(4-1)=4/3

slope of RS=(0-1)/(7-1)=-1/6=-1/6

slope of ST=(4-0)/(10-7)=4/3

slope of  TU=(5-4)/(4-10)=1/(-6)=-1/6

RU||ST

eq. of line RU is

y-y1=m(x-x1)

y-1=4/3(x-1)

3y-3=4x-4

4x-3y-4+3=0

4x-3y-1=0

perpendicular distance of a point (x1,y1) from line ax+by+c=0 is

d=\frac{ax1+by1+c}{\sqrt{a^2+b^2} } \\

perpendicular distance of (7,0) from 4x-3y-1=0

d=\frac{4(7)-3(0)-1}{\sqrt{4^2+(-3)^2} } \\=\frac{28-1}{\sqrt{16+9} }\\=\frac{27}{5} \\=5.4~units
