Answer: it’s congruent
Step-by-step explanation:it’s congruent because DCA AND BCA are both triangles that could make a square like a puzzle because they are the same size.
Answer:
F
Step-by-step explanation:
4.85-4.15=0.7 divided by 2 = 0.35+4.15=4.5*25 cause 30-20=10 divided by 2=5+20=25*4.5=112. closest to that is 120
Answer:
(a) How many grams of copper are in the resulting mixture?
= 160 grams
(b) What percentage of the resulting mixture is copper?
= 61.5%
Step-by-step explanation:
(a) How many grams of copper are in the resulting mixture?
From the question: Suppose that a certain alloy is made by mixing 70 grams of an alloy that contains 12% copper with 90 grams of pure copper.
The number of grams of copper in the resulting mixture = 70 grams + 90 grams = 160 grams
(b) What percentage of the resulting mixture is copper?
70 grams of an alloy that contains 12% copper = 70 × 12%
= 70 grams × 0.12
= 8.4 grams
The number of grams of copper in the resulting mixture = 160 grams
The percentage of the resulting mixture that is copper is
=( 8.4 grams + 90 grams of pure copper/160) × 100
= 98.4/160 × 100
= 61.5%
Answer:
(-2x^4y^2)^3
the solution is -8x^12y^6
Step-by-step explanation:
Answer:
96
Step-by-step explanation:
Use the equation l x w x h, or length x width x height.
8 is the length, 3 is the width, and 4 is the height.
If you multiply 8 x 3 x 4, you get 96.
