Answer:
24
Step-by-step explanation:
subtract 48 from 36 and that equals 12 than add 12=24
Answer:
See below
Step-by-step explanation:
The question is missing information: " . . . how far would he go in an <u>???"</u>
<u></u>
If the question is how far he would go in a [Pick a despised car model} ? The answer is still 400. The car would break down.
If the question is how far would he go in the same amount of time:
Whe the speed limit was 55, it would take Bob (55 miles/hr)*(X hr) = 400 miles
X = 7.273 hours to go 400 miles at 55 mph.
A speed limit of 70 mph would allow Bob the go:
(70 miles/hour)*(7.272 hours) = 509.1 miles
Answer:
A=72
B=18
Step-by-step explanation:
Answer:
sum of the first 12 terms of the sequence. 1, -4, -9, -14, . . = -318
Step-by-step explanation:
The given AP is,
1, -4, -9, -14, . . .
first term a = 1,
common difference d = -4 - 1 = -5
number of terms n = 12
<u>Equation:</u>
Sum of n terms of AP, S₁₂ = n/2[2a + (n - 1)d]
S₁₂ = 12/2[(2*1) + (12 - 1)*(-5)]
S₁₂ = 6[2 + (11*(-5))]
S₁₂ = 6[2 - 55] = 6*(-53) = -318
Therefore sum of the first 12 terms of the sequence. 1, -4, -9, -14, . . = -318
