Answer:

True

Step-by-step explanation:

"Positions to the left of the origin are negative. Distance is the absolute value of the displacement. Distance is always positive and tells how far something is from something else but does not tell us whether it is to the right or to the left."

The balance of errands average balance checking account at the beginning of last cycle was $400 and the only transaction for the

Tom [10]

Answer:

$300

Step-by-step explanation:

Here we are given:

Balance at the beginning of last cycle(first half) = $400

Balance halfway through the cycle(second half cycle) = $200

To find the amount Aaron's checking account pay interest last cycle, let's find the average balance.

Use the formula for average:

$\frac{Bal 1 + Bal 2}{2}$

$\frac{400 + 200}{2}$

$\frac{600}{2} = 300$

Average = $300

Therefore, the amount Aaron's checking account pay interest last cycle is $300

Find the Surface Area of this Prism

zvonat [6]

Answer:

Surface Area= 432m2 / Volume= 960m3

Step-by-step explanation:

Surface Area = 2(1/2bh) + LW+LW

( 8m x 4m ) + ( 8m + 6m + 6m )20

(32) + (20)20

Surface Area = 432m2

Total Volume = (BXHXL) / 2

8m x 12m x 20m/2=

1920/2

V = 960m3

The ideal mass for a piece of chocolate is 2.5 ounces. The actual mass for a production can vary by, at most, 0.08

Nady [450]

Answer:

$2.42\,oz \leq m_{real} \leq 2.58\,oz$

Step-by-step explanation:

The inequality must be the absolute value of the difference between real mass and ideal mass less or equal to 0.08 ounces. That is to say:

$|m_{real} - m_{ideal}| \leq 0.08\,oz$

$|m_{real} - 2.5\,oz| \leq 0.08\,oz$

There are two extreme cases:

$m_{real,max} - 2.5\,oz = 0.08\,oz$ and $m_{real, min} - 2.5\,oz = -0.08\,oz$

$m_{real, max} = 2.58\,oz$ and $m_{real,min} = 2.42\,oz$

Range of chocolate masses must be:

$m_{real, min} \leq m_{real} \leq m_{real,max}$

$2.42\,oz \leq m_{real} \leq 2.58\,oz$
