1 = 4 quarters
2 = 8 quarters
3 = 12 quarters
4 = 16 quarters
5 = 20 quarters
6 = 24 quarters
7 = 28 quarters
ooops. too much
6 and 3/4 = 27 quarters
Answer:
B. 12/5
Step-by-step explanation:
Opposite side of <S is RT = 12
Adjacent side of <S is ST = 5
Tan = Opposite / Adjacent
So
Tan(S) = Opposite / Adjacent
= RT/ST
= 12/5
Answer is B.
The equation is already solved
Answer:
D) 8x²-172x+120
Step-by-step explanation:
Length=2(-2x+20)+6
Width=-2x+20
(-4x+40+6)(-2x+20)
(-4x+46)(-2x+20)
8x²-80x-92x+920
8x²-172x+920
Part A:
Variable is a symbol for a number we don't know yet. It is usually a letter like x or y but can be any letter.
Example: 6z means 6 times z, and "z" is the variable.
Hence, the variables are c and w. [ Choose any one for your answer ]
Coefficient is any number used to multiply a variable.
<span>Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient.
</span>
Hence, the coefficients are 20 and 5. [Choose any one for your answer]
A constant is a<span> fixed value which does not change regardless of the variables entered.
</span>
Hence, the constant is 95.50
Part B:
Weeks saved (w) = 20
Cars washed (c) = 5
20c + 5w + 95.50 = (20 * 5) + (5 * 20) + 95.50 = 100 + 100 + 95.50 = 295.50
Hence, Marla will have $ 295.50 in her account.
Part C:
In <span>20c + 5w + 95.50, Marla's mom deposits $ 20 after every car wash.
If Marla's mom deposits only $ 10 after every car wash, then, the new equation would be : 10</span><span>c + 5w + 95.50
Hence, the coefficient will change from 20 to 10. </span>
