Answer:
last week = 150 minutes
this week = 162 minutes
changes = 162-150
= 12 minutes
percentage of changes = (12/150) × 100
= 8%
Answer:
The answer is 7 x + 3 =24 because its a problem solving
The general formula for geometric series is tn = a×rⁿ⁻¹. In this question, a (or a1) is 3, and r is 1.1, therefore the first ten terms would be 3×1.1⁰ (3) , 3×1.1¹ (3.3), 3×1.1² (3.63) and so on up until you get to 3×1.1⁹ or 7.07.
2 42/100 turn it to a fraction
Set up ratio problem
.2 oz butter / (1/15) lb jelly = x / 1 lb jelly
Then cross multiply the stuff opposite each other in the fractions... set it up as a multiplication problem
.2 × 1 = (1/15) × x
.2 = (1/15)x
Multiply both sides of equation by 15 to clear out the (1/15) fraction and get x
x = 3
