Yeah that is correct. 3/4 is equal to .75
1 week = 7 days
10 weeks = 10×7 days
= 70 days
if Ellen reads 1 book in a day
Therefore,
1 day = 1 book
70 days = 70×1
= 70 books.
Thus Ellen reads 70 books in 10 weeks.
Hope helps
We will see that the exponential decay function is:
f(x) = 175*(0.8)^x
<h3>
How to find the exponential decay?</h3>
The general exponential decay is:
f(x) = A*(1- r)^x
Where:
- A is the initial value.
- r is the rate of decay in decimal form.
- x is the variable, in this case is the time.
Here we know that the initial value is 175, and the rate of decay is 20%. To get this in decimal form, we just divide it by 100%.
20%/100% = 0.2
Replacing that in the exponential function, we get:
f(x) = 175*(1 - 0.2)^x
f(x) = 175*(0.8)^x

Answer:
fraction is 75/100
decimal is 0.75
Step-by-step explanation:
because there are 75 of them that are shaded out if 100 so 75/100 and to find out in decimal 75÷100=0.75.
hope this helps u understand:)
<span>The extra cost can be calculated by working out the total he has spent and subtracting the value of the truck. He spends $1500 on a downpayment and (350 x 10 = $3500) on monthly payments, giving him a total outlay of $5000. This means he overspent by $500. $500 interest was paid for 10 months, so at that same rate, $600 would have been paid for 12 months. $600 as a percentage of the cost of the truck minus the down payment ($3000) is 20%. </span>
