Answer:
<h2>D) $1.05 ÷ 3</h2>
Step-by-step explanation:
Quarter = 0.25
Nickel = 0.05
3 Quarters = 0.25 * 3 = 0.75
6 Nickels = 0.05 * 6 = 0.30
Add to find the total amount of money they have:
0.75 + 0.30 = 1.05
They have to split it equally:
1.05 / 3
Answer: By moving from sea level to Mexico City air pressure is reduced by 25%.
Step-by-step explanation:
Hi, to answer this we have to apply a decrease rate formula
P0 (1-r)^x
Where:
p0= initial pressure
r = decrease rate. (0.4 = 0.4/100=0.004 decimal form)
x = feet (hundredths, since the air pressure decays every 100 feet we have to divide the input value by 100)
Replacing with the values given
P0 (1- 0.4/100)^(7340/100) =
P0 (0.996)^73.4 =
P0 ( 0.75)=
The air pressure at Mexico City compared to the sea level is 75% (0.75 x 100 =75%)
To obtain the percent decrease
100% -75% =25%
Answer:
- 3 large boxes
- 9 small boxes
Step-by-step explanation:
The purchase can be grouped into groups containing one large box and 3 small boxes. Then each group will have 12 +3·6 = 30 granola bars.
Since 90 bars were purchased, the camp bought 90/30 = 3 groups of boxes of bars.
They purchased 3 large boxes and 9 small boxes of bars.
