Step-by-step explanation:
609/504 = 1.208333333
58/48 = 1.208333333
They are proportional since they divide to the same number.
Answer:
a)
b) l=19.2 units
Step-by-step explanation:
a)Let F represent the force and l represents the length of the wrench handle.
Then inverse variation relation is:
When we introduce the variation constant, we get:
From the question when F=96, l=12
The equation is
b) If a person can only exert 60 pounds of force on a wrench,then
Hence the length of the wrench must be 19.2 units
Answer: 168/25
Step-by-step explanation:
Convert to a mixed number by placing the numbers to the right of the decimal over 100
. Reduce the fraction. Then, convert the mixed number to an improper fraction by multiplying the denominator by the whole number and adding the numerator to get the new numerator. Place this new numerator over the original denominator.
168/25
Answer:
Part 1) The radius is 6 in and the diameter is 12 in
Part 2) The area of the dinner plate is
Step-by-step explanation:
we know that
The circumference of a circle is equal to
Part 1) What are the
radius and diameter of the dinner plate?
we have
assume
substitute in the formula and solve for the radius r
Find the diameter
The diameter is two times the radius
so
Part 2) What is the area of the dinner plate
The area of a circle is equal to
we have
assume
substitute
Answer:
There are a total of 78
Step-by-step explanation:
Here we are to calculate the number of 7th grade students at Willow middle school given the information in the question.
Now, to calculate the number of people that attended the party, we add those that have left to those still remaining = 36 + 34 = 70 students
Now this number equals 90% of students
Thus let’s say the total number of students is x
90/100 * x = 70
90x = 100 * 70
90x = 7000
x = 7000/90
x = 77.77 which is approximately 78 students
