1/9+1/9+1/9 = 3/27 which simplifies into 1/3
but remember you can only add a fraction that has the same denominator m8<span />
In order to find the unit rate of acres per day, or in other words, how many acres can they plant in one day, you must divide 5/8, the number of acres planted, by 4/5, the number of days it took to plant. When you divide the two fractions, first set up an expression:
5/8<span>÷4/5
Then, to make things simpler, turn the division expression into a multiplication statement so that you have 5/8*5/4. Then multiply straight across and you get your answer as 25/32. This means that the workers can plant 25/32 acres per day.</span>
This problem is a present worth problem, where you need to calculate its present amount. this can be solved using the formula:
P = F(1+i)^(-n)
where p is the present value
f is the future value
i is the interest rate
n is the number of years
substituting the given to the formula
P = (500000) ( 1 + 0.1)^(-20)
P = 74,321 is current value of the inheritance that is 500,000 that 20 years from now
Answer: The equations are A= 600 + 125w and A = 1100 + 50w. Look into the steps for more information.
Step-by-step explanation:
Zypel's situation can be represented by the equation, A= 600 + 125w where A is the amount of money she will have after w weeks.
The same way we can represent Joshua's situation by the equation
A = 1100 + 50w where a is also the amount of money he will save after w weeks.
It says that there are 4 weeks in one month which means there will be 16 weeks in 4 months.
Now input 16 into the equations for w and solve for A.
A = 600 + 125(16)
A= 600 + 2000
A = 2600
So Zypel will save $2600 in a 4 months
A = 1100 + 50(16)
A= 1100 +800
A= 1900
So Zypel will save more than Joshua in four months.
Answer:
a. 8
b. 61, 23, 84
Step-by-step explanation:
As we can see, point S is between points R and T, therefore:
- RS + ST = RT
- 7y + 5 + 2y + 7 = 14y - 28
- 9y + 12 = 14y - 28
- 14y - 9y = 12 + 28
- 5y = 40
- y = 40/5
- y = 8
------------
- RS = 7y+5 = 61
- ST = 2y + 7= 23
- RT = 14y - 28 = 84
