Lets do this week by week
beginning pressure 45 pounds
end of week 1
45 *.06 = 2.7
45 - 2.7 = 42.3
end of week 2
42.3 * .06 = 2.538
42.3 - 2.538 = 39.762
end of week 3
39.762 *.06 = 2.38
39.762 - 2.38 = 37.37
end of week 4
37.37* .06 = 2.2425
37.37628 - 2.2425= 35.12
end of week 5
35.12 * .06 = 2.107
35.12 - 2.107 = 33.012
end of week 6
33.012* .06 = 1.98
33.012 - 1.98 =31.03
Here is the fast way to get to this answer.
do 1-.06 = .94
then do
45(.94)(.94)(.94)(.94)(.94)(.94) = 31.04
Answer:
Step-by-step explanation:
Given
Required
Write, using scientific notation
The scientific notation is written in the form:
<em>Where n is an integer and </em>
<em />
To start with; <em>Represent the given number as fraction</em>
Represent the denominator as an exponent
This can be rewritten in form of:
Remember that: <em>Where n is an integer and </em><em />
<em>This implies that; we need to adjust 2711 to a number between 1 and 10;</em>
This gives:
Write 1000 as an exponent
Apply law of indices
The question requires 2 numbers after the decimal point;
So, 2.711 will be approximated to 2.71
Hence;
<em></em>
<em> </em><em>is equivalent to </em>
<em></em>
Answer: B
. $23.42 is your answer
Hailey went to Frank’s Market and bought 1 3/4 pounds of coffee at $13 a pound and 8 1/2 pounds of rice at $0.45 per pound. If Hailey paid for her purchase with a $50 bill, how much change did she receive?
Answer:
$23.43
Step-by-step explanation:
First, you need to find the total amount she needs to pay for the items she purchased:
1 3/4=1.75
8 1/2=8.5
Total purchase=(1.75*$13)+(8.5*$0.45)
Total purchase=22.75+3.82
Total purchase=26.57
No, you need to subtract the total amount you have to pay for your purchase from $50:
$50-$26.57=$23.43
According to this, the answer is that she received $23.43 as change.
Answer:
The answer is 8 1/4

Answer:
The fllor's radius is 3 yd
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference = 18.84yd
r = radius
π = 3.14
c = 2π * r
we replace with the known values
18.84yd = 2 * 3.14 * r
18.84yd = 6.28 * r
18.84yd / 6.28 = r
3yd = r
The fllor's radius is 3 yd
