The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same. For example, when point P with coordinates (5,4) is reflecting across the X axis and mapped onto point P', the coordinates of P' are (5,-4).
Answer:
The answer is A.) R
R is in the correct correspondence with B.
Let x=papers on Saturday and y=papers on Sunday
First make equations for the information given to you
x+y=52 (total papers) and y= x+8 (he sold 8 more on Sunday)
then since you know y=x+8 then substitute it in the other equation like so
x+(x+8)=52 which means 2x+8=52 which means 2x=44 and therefore x=22
the problem however asks for sunday and not saturday, so solve for y now
y=x+8 which means y=22+8 which means y=30
He sold 30 papers on Sunday
Mercury the liquid metal? 674.1°F or 356.7°C
Answer:
Step-by-step explanation:
<u>Find the volume of cylinder:</u>
<u>Convert the dimensions into yards:</u>
- d = 24 inches = 24/36 yards = 2/3 yards ⇒ r = 1/2d = 1/2*2/3 = 1/3 yards
- h = 6 feet = 6/3 yards = 2 yards
<u>Find the volume by substituting the values:</u>
- V = 3.14*(1/3)²*2 = 0.69777 ≈ 0.7 yd³
Correct choice is C
