Answer:
Part 1) 2.1 cups of cream
Part 2) 4.2 cups of dark chocolate
Step-by-step explanation:
we know that
The recipe for 20 chocolate truffles is:
I cup of cream
2 cups of dark chocolate
step 1
Find how many cups of cream are needed for 42 truffles
using proportion
Let
x-----> the number of cups of cream needed
20/1=42/x
x=42/20=2.1 cups of cream
step 2
Find how many cups of dark chocolate are needed for 42 truffles
using proportion
Let
x-----> the number of cups of dark chocolate needed
20/2=42/x
x=42*2/20=4.2 cups of dark chocolate
13-m=2(-4+m)
13-m=-8+m
-m-m = -8-13
-2m = -21
M= -21 : -2
= 10.5
Sorry if I'm wrong ..
3/45 = 20/x...3 in to 45 seconds = 20 in to x seconds
cross multiply
(3)(x) = (45)(20)
3x = 900
x = 900/3
x = 300...300 seconds (or 5 minutes)to fill the tub with 20 inches
86 or 129. how to figure that out: do 43 times 2 and you get 86 :) 43 times 3 is 129. hope this helps :)
The coordinates of the original quadrilateral are (1, 2), (4, 2), (1, 4), and (4, 4). After transformation, the new coordinates are (1, −2), (4, −2), (1, −4), and (4, −4). Thus, as we can see, the y coordinates of the original points have been multiplied by-1. This happens only when there is a reflection about the x axis.
Thus, the type of transformation in question here is reflection about the x axis.
