Place values for 249.673
irakobra [83]
Hi! 

This question is worded a little funny, but i think in understand what it's asking. Forgive me if i'm wrong. 

Place values in math are pretty self-explanatory. It's just asking you what place each number is in.

For example:

If you were to write the number 12, the 1 would be in the tens place and the 2 would be in the ones place. 

When speaking about decimals, you pretty much just have to add the letters 'th' to the end of the place value, but instead of decreasing as the numbers grow smaller, you increase and the ones place doesn't exist. 

So in this case:

With 249.637, 2 is in the hundreds place. 4 is in the tens place. 9 is in the ones place. 6 is in the tenths place. 7 is in the hundreths place. 3 is in the thousandths place. 

Hope this helps :)

What is this graph ?
Eva8 [605]

The slope-intercept form:

y=mx+b

m - slope

b - y-intercept

x-y=1      <em>subtract x from both sides</em>

-y=-x+1     <em>change the signs</em>

y=x-1

It's a linear function.

We need only two points to plotting a graph.

We choose any three values of x and calculate y.

for\ x=0\to y=0-1=-1\to(0,\ -1)\\for\ x=1\to y=1-1=0\to(1,\ 0)\\for\ x=2\to y=2-1=1\to(2,\ 1)

Translate Δ A B C 6 units horizontally. How are the values in the ordered pairs affected by the translation?
snow_tiger [21]

Answer:

The x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.

Step-by-step explanation:

The given triangle has vertices at A(-4,1), B(-2,1) and C(-2,4)

The transformation rule for a horizontal translation by k units is

(x,y)\to (x\pm k,y)

In this case we have k=6

A(-4,1)\to A'(-4\pm6,1)

B(-2,1)\to B'(-2\pm6,1)

C(-2,4)\to C'(-2\pm6,4)

Therefore the x-coordinates are translated 6 units to the left or right while the y-coordinates are not affected.

35 percent of the students are boys which is 259 find the total number of the students and girls​
Amanda [17]

Answer:

740 total students, 481 total girls

Step-by-step explanation:

Let x be the total number of students and y be the total number of girls

x -

You know that 35% of the students is 259 students. If you convert this into algebra, you can write : 0.35x = 259, after simplifying, you know that x = 740.

y-

You know that 35% of the students are boys, so 65% must be girls. You can say that 65% of x is y and write the equation 0.65(740)=y. After simplifying, you can see that y = 481.

I hope this helps :)
