Can you simplify 1000^2/3

1 answer:

6 0

No. You cannot simplify 1000^2/3 because when you multiply 1000 by 1000, you will get 1,000,000. And when you divide 1,000,000 by 3, you will get a long decimal number. This means it cannot be simplified equally. Making the answer a "NO".

Graph the line with slope -1/3 passing through the point (4,-2)

damaskus [11]

Y = mx + b
slope(m) = -1/3
(4,-2)...x = 4 and y = -2
sub and find b, the y int
-2 = -1/3(4) + b
-2 = -4/3 + b
-2 + 4/3 = b
-6/3 + 4/3 = b
-2/3 = b

so ur equation is : y = -1/3x - 2/3....or x + 3y = -2

ur y int is (0,-2/3)....ur x int is (-2,0)...ur slope is -2/3....other points on ur line include (1,-1) , (4,-2) , (7,-3), (10,-4), (-5,1), (-8,2)...plot these points...u should be able to see ur line from this

Answer:

choices A and F are part of Leo's system of equations

Step-by-step explanation:

The formula for the amount in an account compounded annually is ...

A = P(1 +r)^t

For the given amounts and variables, that is ...

y = 500(1.025)^x . . . . matches F

The formula for the amount in an account compounded continuously is ...

A = P·e^(rt)

With given values, this is ...

y = 400e^(0.02x) . . . . matches A

a group of students attend math club. Half of the students are boys and 4/9 of the boys have brown eyes. What fraction of the gr

Rus_ich [418]

In pretty sure the answer would be 4/18. I think it would be this because If half the students are boys and 4/9 of the boys have brown eyes, this means that the whole club is 18. You add the two denominators. This equals the whole. Since it is asking for boys with brown eyes out of the whole group you put the number of brown eyed boys over the total number of kids.

On the trip from Detroit to Columbus, Ohio, Mrs. Smith drove an average speed of 60 mph. Returning, her average speed was 55 mph

Anna11 [10]

Remember that Distance = (Average speed)(Time)
Let x be the distance between Detroit and Columbus.
We know the journey from Detroit to Columbus took a time t, and the returning trip took a time t+ $\frac{1}{3}$ . We also know the Average speed of both journeys, so now we can set our equations:
$\left \{ {{x=60t} \atop {x=55(t+ \frac{1}{3}) }} \right.$
Now, we can replace equation 1 into equation 2 to find t:
$60t=55(t+ \frac{1}{3} )$
$60t=55t+ \frac{55}{3}$
$5t= \frac{55}{3}$
$t= \frac{11}{3}$

Now that we know t, we can replace it into our equation 1 to get the distance:
$x=(60)( \frac{11}{3} )$
$x=220$

We can conclude that the distance between Detroit and Columbus is 220 miles. <span />

Find the area of the surface of the part of y=4x+z^2 that lies between the planes

adelina 88 [10]

Y) Recorder $4x$ and $z^2$

$y=z^2+4x$

X)Solve for $x$ by simplifying both sides of the equation, then isolate the variable

$x=- \frac{ z^{2} }{4}+ \frac{y}{4}$

Z)Take the root of both sides and solve.

$z= \sqrt{-4x+y}, - \sqrt{-4x+y}$
