Answer: 98
Step-by-step explanation:
98 / (-7) = -14
d = 3 , a₁₂ = 40 and S
= 7775
In an arithmetic sequence the nth term and sum to n terms are
<h3>• a
= a₁ + (n-1)d</h3><h3>• S
=
[2a + (n-1)d]</h3><h3>
where d is the common difference</h3><h3>a₆ = a₁ + 5d = 22 ⇒ 7 + 5d = 22 ⇒ 5d = 15 ⇔ d = 3</h3><h3>a₁₂ = 7 + 11d = 7 +( 11× 3) = 7 + 33 = 40</h3><h3>S₁₀₀ =
[(2×7) +(99×3)</h3><h3> = 25(14 + 297) = 25(311)= 7775</h3>
12.) m=26
19-(-7)/-1-(-2)=26
13.) 14
8-(-20)/5-3=14
14.) -4/5 is the slope
Count rise over run and always make sure whether to add a negative based on the direction of the line. In this situation, the line is negative so there is a negative sign present.
Answer:
66.3 mL
Step-by-step explanation:
17.4% of 381 mL is ...
0.174 × 381 mL = 66.3 mL
0.75^2 = 0.5625.....sq rt 0.5625 = 0.75
