Do the product 40x500 and 40x600 have the same number of zeros
VARVARA [1.3K]

No they do not have the same number of zeroes

Although the 2 products do seem like they might have the same number of zeroes, 40 x 500 and 40 x 600

both have 3 zeroes before multiplying

if we take the first 2 digits of the 2 numbers being multiplied to get an idea of the answer

 if we take 40 x 500 - 4 x 5 = 20

then theres an extra zero added

but if we take 40 x 600 - 4 x 6 = 24

no extra zeroes added to this


so if we finally look at the answers

40 x 500 = 20 000

40 x 600 = 24 000

20000 has 4 zeroes and 24000 has 3 zeroes


so the answer is no they dont have the same number of zeroes

Write an equation of a line parallel to y=10x+6 and going through point (2,-4)
nadya68 [22]

Answer:

Y= 10x-24 would be parralel to y=10x+6

Step-by-step explanation:

well a parralel line has to have the same slope and a different y-intercept.

To find the y-intercept the x has to be exactly 0.

So we have (2,-4)

The slope is 10/1 which is 10y and 1 x which in an ordered park would be Add 1 x and add 10 y. But we’re trying to get x to be 0 to find the y-intercept.

So subtract 1 x and subtract 10y

2-1=1

-4-10=-14

(1, -14)

1-1=0

-14-10=-24

(0, -24)

THe y-intercept is -24 and w have the slope since its the same thing So

y=10x-24 is the equation

Can someone help me with solving volume equations?
Helen [10]

Answer:

For <em>2</em>, 30 cubic m., For <em>3</em>, 90 cubic cm., For <em>4</em>, 1000 cubic yards, for <em>5</em>, 27 cubic mm., For <em>6</em>, 120 cubic in.

Step-by-step explanation:

You can simply multiply all 3 sides to get the cubic volume B x <em>h </em>is the same as<em> l</em> x <em>w </em>x <em>h</em>

<em />

<em>ex. </em>Number 2, length 3, width 2, height 5

Base is<em> 2x3=6 </em>times <em>5 = 30 </em>or<em> 2 x 3 x 5=30</em>
