A circular garden has a circumference of 88 yards. Lars is digging a straight line along a diameter of the garden at a rate of 7 yards per hour. How many hours will it take him to dig across the garden? Use 3.14 for π and round the diameter to the nearest whole number, if necessary.
Answers
Answer:
It will take 4 hours to dig in the garden
Step-by-step explanation:
First we have to calculate the diameter, for this we will use the formula to calculate the circumference of a circle and we will clear the diameter
d = diameter
π = 3.14
c = circumference
c = π * d
d = c / π
d = 88yd / 3.14
d = 28.025yd
round to the nearest whole number
28.025 = 28
d = 28yd
To know how many hours it takes, we divide the diameter by the speed
t = time
v = velocity
t = d / v
t = (28yd) / (7yd/h)
t = 4h
It will take 4 hours to dig in the garden

Step-by-step explanation:
The way the quadratic equation was given, we can't have a factored form in the format:
First, divide both sides by 2
Now, it is about thinking. From the equation, we will get something in the format:
Let's expand this:
From here, we can give some values for those variables, based on the quadratic equation :
Once we want the middle term to be -4 and bd to be 4, we can easily evaluate the other variables.
Therefore,
But we are not ready yet!
This is the factored form of , to get the factored form of the problem equation, just multiply the factored form we got by 2.

we find that the total annual income is $40,178.57.
To find the total annual income, we need to subtract the amount spent on clothing and savings from 100%.
Clothing and savings make up 16% of the income, so the remaining 84% is used for other expenses.
Let's call the total annual income 'x'.
The equation can be written as:
84% of x = $33,750.
To solve for x, we can set up a proportion: 84/100 = $33,750/x.
Cross multiplying gives us 84x = $33,75000.
Dividing both sides by 84,
we find that x = $40,178.57.

If 18,600 is 31% of X then X x .31 = 18,600
Then solve for X
18,600 / .31 = 60,000
Then check your answer:
31% of 60,000 is 60,000 x .31 = 18,600
