4) 12-20 - 2t Help ?

Mathematics
1 answer:
ahrayia [7]3 years ago
5 0

Answer:

-2t - 8

Step-by-step explanation:

First, we do 12-20. An easy method to do that is to swap it around like 20-12 and do that to get 8 and then put a negative sign next to and get -8.

We have 2t left which ends up as:

-2t - 8

A heart beat takes 0.8. how many seconds os it written as a fraction
Drupady [299]

The problem is asking you to convert 0.8 into fraction form. The number 0.8 is in decimal form and to change it to fraction form you have to get the number after the decimal point which is 8 in this problem.

8 would be the numerator of the fraction. Next step is to count how many numbers are there after the decimal point. In this problem, there is only one number so there will only be one zero beside 1 (10). 10 will be the numerator.

So, the fraction would be 8/10 or 4/5 (simplified form)

Please help me with this

Answer:The difference between the medians is 2.5

Step-by-step explanation: So how I did this is first I found the median of the two plots (median=the middle number in a group of values) so anyway I lined it all out because I find it easier to do it that way (20,25,25,30,30,30,30) so the answers I got for both plots were -plot A=32.5 and plot B=30 than difference means subtract so 32.5-30=2.5

Kite KLMN has vertices at K(1,3) L(2,4) M(3,3) N(2,0). After the kite is rotated, K' has coordinates (-3,1). Describe the rotati
gregori [183]

The coordinates of L ', M' and N ': (-4,2); (-3.3); (0.2)

<h3>Further explanation </h3>

Transformation is a change in shape or change in location from a building to another build.

A build can be changed in shape or location using transformation

There are several forms of transformation, including translation, dilation, rotation or reflection.

Rotation is a change in the position of an object because it is rotated with certain angles and centers

Generally for rotations with angles of 90 and 180:

  •  center (a, b)

90 °: (x, y) → (-y + a + b, x -a + b)

180 °: (x, y) → (-x + 2a + b, -y + 2b)

  • center (0,0)

90 °: (x, y) → (-y, x)

180 °: (x, y) → (-x, -y)

K (1,3) L (2,4) M (3,3) N (2,0). After the kite is rotated, K 'has coordinates (-3,1)

If we look at coordinates K -> K ' meets the 90 ° rotation rule: (x, y) → (-y, x) with a center of 0.0

so the coordinates of another point

 L (2,4) ---> -4,2

M (3,3) ---> -3,3

N (2.0) ----> 0.2
