(a^3-2a^2)-(3a^2-4a^3)
(a^3-2a^2)-3a^2+4a^3
5a^3-5a^2
3) HK = 2√5
midpoint of HK = (8,8)
4) SR = 2√2
R = (6,2)
5) Instead of walking a total of 14 he only would have walked a total of 10.
Hope this helps! ;)
Part 1) <span>Each sandwich costs $.02 per cubic inch to make. What is the cost of each sandwich?
</span>volume for cube sandwich is 125 in³
volume for pyramid sandwich is 41.67 in³
cost of each cube sandwich=0.02*125-----> $2.5
cost of each pyramid sandwich=0.02*41.67-----> $0.83
the answers Part 1) are
a) cost of each cube sandwich is $2.5
b) cost of each pyramid sandwich is $0.83
Part 2) <span>If each sandwich sells for $4.00 and Mr. Sammie sells 100 Cube sandwiches and 100 Pyramid Sandwiches, how much profit would Mr. Sammie make?
</span>
we know that
Profit=Sells-Costs
step 1
find the sells
Sells=200*$4-----> $800
step 2
find the costs
Costs=100*$2.5+100*$0.83----> $333
step 3
find the profit
Profit=Sells-Costs
Profit=$800-$333-----> $467
the answer Part 2) is
the profit is $467
Solution:
We have to prove that ,
△ABC ~ △Z Y X Using SAS.
It is given that , ∠X ≅ ∠C .
You must keep in mind when two triangles are similar by S A S
1. The included side between the angle should be Proportional.
2. We have to prove that ,
△ABC ~ △Z Y X Using SAS.
It is given that , ∠B ≅ ∠Y .
The included side between the given angle should be Proportional.
3. We have to prove that ,
△ABC ~ △Z Y X Using SSS.
The three sides of two triangles must be Proportional.
