Answer:
Assuming the similarity is that BC scales to EF, answer is
D. 1.5BC
Step-by-step explanation:
Because the triangles are smilar, AB/BC = DE/EF
If AB = 2BC
then DE = 2EF
but also DE = 3BC
so 2EF = 3BC
EF = 1.5BC
Answer:
The domain in interval notation is [-4,∝) or set build: {x|x
Step-by-step explanation:
I'm assuming the 9x and the 36 are in the root
first we must solve for x
substract 36 to both sides
divide by 9 to both sides
simplify left side
simplfy right side
The domain in interval notation is [-4,∝) or set build: {x|x-4}
Answer:
Yeah
Step-by-step explanation:
Check the picture below.
Make sure your calculator is in Degree mode.
N=number of nickles
d=number of dimes
q=number of quarters
use cents for everything
total value=585
5n+10d+25q=585
divide everybody by 5 to simplify
n+2d+5q=117
we have
nicles are 5 more than quarters
n=5+q
4 times as many dimes as quarters
d=4 times q
d=4q
sub those in
5+q+2(4q)+5q=117
5+6q+8q=117
5+14q=117
minus 5
14q=112
q=8
sub back
n=5+q
n=5+8
n=13
d=4q
d=4(8)
d=32
13 nickles
32 dimes
8 quarters
divide both sides by 22
