Answer:
total question =90
she obtained 75% of first 40 questions
- No. of question she got correct in first 40 = 75% * 40 = 30
2. in order to get 80% out of 90,
the no. of questions got correct by Ama = 80% * 90 = 72
3. As she already got 30 c0rrect in first 40 questions, the number of question she needs correct for remaining 50 = (72-30) = 42
percentage = 42/50*100% = 84%
3/4(8p+12)+3/8(16p-8)
=3/4[(8p+12)+1/2(16p-8)]
=3/4[8p+12+8p-4]
=3/4[16p+8]
=3/4*8*[2p+1]
=6[2p+1]
=12p+6
Answer:
CPCTC - Corresponding Parts of Congruent Triangles are Congruent
Step-by-step explanation:
When two triangles are congruent, this means they have the same shape and the same size. To have the same shape, each angle must be congruent. To have the same size, each side length must be congruent. When you know two triangles are congruent you can say each corresponding part of congruent triangles is congruent. This is known as CPCTC.
Answer:
ab= 7.8
ac= 6
bc=5
Step-by-step explanation:
5y - 3y + 12
Because there is not a common factor between the three terms in it's current state, we must simplify.
2y + 12
Now, we can simplify using the distributive property.
Factor 2.
<h3>2(y + 6) is the factored form of the original expression.</h3>
