What is the name of the period that has the digits 486 in the number 751,486.
Answers
the period is the tenths, hundreds and thousands because the are behind the decimal or the comma
Which is an expression to find the speed in m/s? d = 40 meters, t = 10 seconds A. 40/10
B. 40x10
C. 10/40
D. 40+10
Answers
The answer is A because the equation is 40/10 which would give you 4 and it asks m/s.
D ÷ T = S A is correct because to find the speed you have to divide the distance by the time. The answer is 4.
Best Method using system of equations
x=4y+8 2x-8y=-3
Answers
In this case, since one equation is in the form of x=, substitution would be best for this problem. Simply plug in 4y + 8 in place of x in the second equation, solve for y, then plug that value into the first equation to find x.
X=4y+8 2x-8y=-3
lets use the substitution method 2x-8y=-3 2(4y+8)-8y=-3 8y+16-8y=-3 16 is not equal to -3 so lets try elimination
x=4y+8 2x-8y=-3
xhange the 1st equation to standard for x-4y=8 2x-8y=-3
multiply the 1st equation to remove x 2x-8y=8 2x-8y=-3 0 is not equal to 11
therefore we cannot solve using both equations so te question's answer is undefined

PLEASE help with these math questions
Answers
all of these are applications of the distance formula remember a^2+b^2=c^2 so the distance (c) is a and b are legnths of legs so we find the legnths
the distance between points (x1,y1) and (x2,y2) is
D= input points and find distance
1. (3,5) ot (7,3) D==√(16+4)=√20=4.47 answer is A
2. (-3,-2) to (4,6) D==√(49+64)=√113=10.63 answer is 10.6 units
3. from (1,7) to (9,-2) D==√(64+81)=√145=12.04 answer is B
4. (-1,-2) to (6,2) D==√(49+16)=√65=8.06 round 8.1 units
5. apply multipule times A=(2,2) B=(12,2) C=(9,8) D=(2,8) find the distance between A to B B to C C to D D to A we can see the distances between AB, CD and AD easily just since 1 variable doesn't change, we just find the change in the other variable AB=10 units CD=7 units DA=6 units now CB is from (12,2) to (9,8) D==√(9+36)=√45=6.7
add everybody AB+BC+CD+DA=10+6.7+7+6=29.7 we see that they put a trick and see option D, the not careful people will chose that but the quesiton askes for the perimiter
answer is B
How can I write a story about the doubles plus 2 fact 5+7=12.??
Answers
One possible story is:
I had 5 apples. My sister gave me 7, and now I have 12.
Explanation:
We are writing a story for 5+7=12. This means we need to start with 5 objects and somehow gain 7 more. In our story, we start with 5 apples and we get 7 more.
The last part is that our total must be 12. In our story, we end with 12 apples.
Here's a story: I had 5 dollars in my piggy bank. My mother gave me 7 more dollars for cleaning my room. I now have 12 dollars. (:
