Mathematics

Answer:

22/10 or 2 and 1/5

Step-by-step explanation:

To find the perimeter, add all sides together. Since it's a rectangle, the other sides are the same measurement as the ones given. Add 3/10, 3/10, 4/5, and 4/5 together. To do this, find a common denominator. The lowest common denominator is 10 so multiply the 4/5 by 2/2 to get the denominator to be 10. Now, add 3/10, 3/10, 8/10, and 8/10. It adds up to 22/10 but if you don't want an improper fraction, simplify it to 2 and 1/5.

Help me please i do not understand it.

Answer:y = 2x + 4

Explanation:

1) The slope - intercept form is of the kind y = mx + b, where m is the slope and b is the y-intercept.

2) Given two points you can find the slope (using the two points) and then the equation using one of the points.

3) slope = m = Δy / Δx

points given (3,10) , (0,4)

m = [y2 - y1] / [x2 - x1] = [10 - 4] / [3 - 0] = 6 / 3 = 2

4) equation

y - y2
-------- = m
x - x2

  y - 4
---------- = 2
  x - 0

=> y - 4 = 2 (x - 0)

y - 4 = 2x

y = 2x + 4

I have 5 digits. My q is worth q * 10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as mu
Scilla [17]

Answer:

92,776

Step-by-step explanation:

I have 5 digits. My 9 is worth 9*10,000. My 2 is worth 2 thousand. One of my 7s is worth 70. The other is worth 10 times as much. My other digit is a 6. What number am I?

My 9 is worth 9*10,000 = 9 * 10,000

= 90,000

My 2 is worth 2 thousand = 2,000

One of my 7s is worth 70 = 70

The other is worth 10 times as much = 70 * 10

= 700

My other digit is a 6 = 6

The number is

90,000 + 2,000 + 700 + 70 + 6

= 92,776
