2/1 or 2
either or is correct, just depends on how your teacher prefers your answers to be
Slope of the line is -3/2
Step-by-step explanation:
- Step 1: Given points are (1, -2) and (3, -5)
- Step 2: Equation for slope, m = (y2 - y1)/(x2 - x1)
⇒ m = (-5 - -2)/(3 - 1) = -3/2
Answer:
$32.25
Step-by-step explanation:
$53.75 ÷ 5 = $10.75
$10.75 × 3 = $32.25
Answer:
Case1:
Men : 30
Work : 1
Time (day×hr): 56×6 = 336 hr.
Case2:
Men : let it be m men.
Work: 1
Time: 45×7 = 315 hr.
Work being constant in both cases, men and time are in inverse proportion i.e, more men take less time.
Product of men and time is constant in both cases.
Therefore, 30×336=m×315
Or, 30×336/315 = m
Or, m = 32.
Hence, required number of men is 32.

Answer:
Step-by-step explanation:
pythagorean theorem. a^2+b^2=c^2
1.5^2+b^2=6^2
2.25+b^2=12
12-2.25=b^2
b^2=9.75
take the square root
b=3.12
