Answer: A 40 feet
Explanation:
If a building is 380 feet tall and the elevator has to descend 420 feet to get to the underground parking garage. So 420 - 380 to remove the height of the building from the equation. This would give us 40 feet underground left until the elevator reaches its desired destination.
Answer:
A. 8/10
Step-by-step explanation:
(0.8 × 10) / (1 × 10) = 8/10 (since, multiplying 10 shifts the decimal point towards the right by one place)
Further, we can reduce fractions 8/10 by dividing the numerator and denominator by 2.
(8 ÷ 2) / (10 ÷ 2) = 4/5
Thus, 0.8 as a fraction is 8/10 or 4/5
Answer:
Slope = 4/3x; y-intercept = -1
Step-by-step explanation:
y + 1 = 4/3x
You have to write this equation in slope-intercept form (solve for y) if you want to find the slope and y-intercept
y + 1 = 4/3x
Subtract one from both sides
y + 1 - 1 = 4/3x - 1
y = 4/3x - 1
Now that we have the equation, you can now find the slope and y-intercept
y = mx + b; m is the slope and b is the y-intercept
So for y = 4/3x - 1, the slope is 4/3x and the y-intercept is -1
Answer: The large jar has the best value for the money.
Step-by-step explanation:
Hi, to answer this question we have to divide the price of each jar by the corresponding weight.
Large jar = 1.54 / 440 = £0.0035 per gram
Small jar = 1.26 /340 =£ 0.003705 per gram
Since 0.0035<0.003705
The large jar has the cheapest price per gram, so it has the best value for the money.

Answer:
4200
Step-by-step explanation:
Time taken by Lester 30 seconds
Time taken by Ralph = 35 seconds
Their rate :
Lester = 1/time taken = 1/30
Ralph = 1/ time taken = 1/35
Combined rate:
1/30 + 1/35 = (35 + 30) / 1050 = 65 / 1050 = 0.0619047 per boot
Time taken = number of boots / combined rate per boot
Time taken = 260 / 0.0619047
Time taken = 4200 seconds
