Answer:
B 36
Step-by-step explanation:
DC^2=6^2+8^2. AD=9cm DB=6cm
DC^2=36+64
DC^2=100
DC=√100
DC=10cm
AC^2=15^2+8^2
AC^2=225+64
AC^2=289
AC=√289
AC=17
P OF TRIANGLE ADC=10+9+17
=36cm

4x + 72 + 2x - 12 = 180
6x + 60 = 180
6x = 180 -60
6x = 120
x = 120/6
x = 20</span>
Let x + 15 = total penguins
15/ (x +15) = .30
15 = .30x + 4.5
.30x = 10.5
x = 35
Total penguins = 15 + 35 = 50
Double Check
15 / 50 * 100 = 30% Correct!!!
Answer:
9a⁶b³c⁹
Step-by-step explanation:
Just divide the 27 by 3 since 27a⁶b³c⁹ is a single number
The slope is -5.
The point is (-3, 4)
The formula for point slope form is
y-y1=m(x-x1) where y1 and x1 are the coordiantes of the point and m is the slope.
This shows that the y coordinate is positive and the x coordinate is negative.
May seem counterintuitive. So just flip signs that you see in formula to make the actual point if you are confused.
