Find the DIAMETER of a circle for the circumference given.
circumference = 81 km
A) 4 km B) 10 km
C) 12 km D) 8 km
Answer:
25.796... km
Step-by-step explanation:
We are given that:
Circumference: 81 kmFormula of circumference:
2πr or πdThus, we can rewrite the circumference as:
2πr = πd = 81 kmSince we are asked to determine the diameter, it is recommended to use the formula (πd). Therefore,
πd = 81 kmDivide π both sides to isolate the diameter:
⇒ πd/π = 81 km/π ⇒ d = 81 km/πSubstitute π as 3.14 and simplify:
⇒ d = 81 km/3.14 ⇒ d = 25.796... kmTherefore, the diameter of the circle is 25.796... km.
Which expression represents the phrase below?
8 less than the product of 6 and a number, x
A. 8 - 6x
B.6x-8
C.(6+x)-8
D.8-(6+x)
Answer:
B
Step-by-step explanation:
The number is x and you want 6 of that, so that makes 6x
You want 8 less of this, so subtract 8
Therefore you get 6x - 8
Answer:
B
Step-by-step explanation:
8 less than the product of 6 and x gives the expression 6x-8.

A company uses 1/4 of a barrel of chocolate chips to make each batch of granola bars. In one day, the company uses 3 1/2 barrels of chocolate chips to make granola bars. How many batches of granola bars did the company make in the day? Can anyone show me the method.
Answer:
14 times.
Step-by-step explanation:
It is how many times 1/4 go in 3 1/2.
3 1/2 as an improper fraction is 7/2.
To make them have the same denominator, we have to change 7/2.
7 x 2 = 14
2 x 2 = 4
So, how many times does 1/4 go in 14/4?
14 times.

What is triangle?A triangle can be referred to as a polygon with three edges and three vertices.
we can arrange length of one side of a unique triangle in 3 different ways.
Let x,y,z be the length of the three sides.
For triangles to be unique, length of one side can be arranged in 3 different ways.
Then, length of 6.5 cm can be at maximum three positions which is x,y,z.
The 2.5 cm lenght can appear to be at maximum three positions which is x,y,z.This can as well be done for 6cm.

A piece of string is 120 centimeters long.
How long would the piece of string Measure in meters?
Picture:
Answer:
1.2 m
Step-by-step explanation:
1 meter = 100 cm
120-100(1m)=20
.2 meters would be 20 cm if we're going by 1 m = 100cm.
We already have 1 meter from 100 cm and then we add the .2 meters to the 1 meter. 1+.2= 1.2 m

simplify 1/6^3 divided by 1/36
Answer:
1/6
Step-by-step explanation:
To simplify the expression:
1. Change the divisor into it's reciprocal
2. Change the sign into a multiplication sign.
3. Evaluate the product of those fractions.
4. Simplify the fraction. (If possible)
Given expression:
[tex]\dfrac{1}{6^3 } \div \dfrac{1}{36}[/tex]
According to step 1, we need to convert the divisor of the expression into it's reciprocal.
[tex]\dfrac{1}{6^3 } \div \dfrac{36}{1}[/tex]
According to step 2, we need to change the division sign (÷) into a multiplication sign (×).
[tex]\implies \dfrac{1}{6^3 } \times \dfrac{36}{1}[/tex]
According to step 3, we need to determine the product of these fractions. This can be done by evaluating the exponent.
[tex]\implies \dfrac{1}{(6)(6)(6) } \times \dfrac{36}{1}[/tex]
[tex]\implies \dfrac{1}{216 } \times \dfrac{36}{1}[/tex]
Multiply the fractions as needed. [a/b × c/d = (a × c)/(b × d) = (ac)/(bd):
[tex]\implies \dfrac{36}{216 }[/tex]
According to step 4, (If possible), Simplify the product of 1/216 and 36. In this case, the product of 1/216 and 36 is 36/216. Since both are divisible by 6, we can divide the numerator and the denominator by 6 to simplify the fraction.
[tex]\implies \dfrac{36 \div 6}{216 \div 6 }[/tex]
[tex]\implies \dfrac{1}{6 }[/tex]
Therefore, the quotient of 1/6^3 and 1/36 is 1/6.

Problem 2 Six different jobs need to be done today at the restaurant where you work. You have a pool of nine available workers. If you can assign only one worker to each job and no more than one job to a worker, how many different worker/job assignments are possible
========================================================
Explanation:
The order matters because the jobs are different. This means we'll use a permutation.
We have n = 9 workers to pick from and r = 6 jobs to fill.
Plug those values into the nPr permutation formula.
[tex]n P r = \frac{n!}{ (n-r)! }\\\\9 P 6 = \frac{9!}{ (9-6)! }\\\\9 P 6 = \frac{9!}{ 3! }\\\\9 P 6 = \frac{9*8*7*6*5*4*3*2*1}{ 3*2*1 }\\\\9 P 6 = 9*8*7*6*5*4 \ \ \text{.... Note: The 3*2*1 cancels}\\\\9 P 6 = 60480\\\\[/tex]
There are 60480 ways to assign the 9 workers to the 6 different jobs where order matters.
----------------------
Another approach:
Label the 6 jobs as A,B,C,D,E,F
For job A, we have 9 workers to pick from.
For job B, we have 8 workers to pick from. This is because it states that there is "no more than one job to a worker".
For job C, we have 7 workers to pick from. And so on. We have this countdown going on. We stop once we reach job F.
We end up with 9*8*7*6*5*4 = 60480 different permutations
The string "9*8*7*6*5*4" is found in the second to last step of the section above.

From her eye, which stands 1.66 meters above the ground, Deondra measures the
angle of elevation to the top of a prominent skyscraper to be 70°. If she is standing at
a horizontal distance of 276 meters from the base of the skyscraper, what is the
height of the skyscraper? Round your answer to the nearest tenth of a meter if
necessary.
Answer:
760 m
Step-by-step explanation:
You can draw a right triangle.
For the angle of 70°, 276 m is the adjacent side.
The heigh of the building above 1.66 m is the opposite side.
tan x = opp/adj
tan 70° = h/276
h = tan 70° × 276
h = 758.3
h is the height above 1.66 m.
height = 758.3 m + 1.66 m = 759.96 m
Answer: 760 m

The average attendance at school for 5 days was 264. If the attendance on the 5th day was 256, calculate the average attendance for the first 4 day’s
Answer:
266
Step-by-step explanation:
Let the attendence of 5days be a,b,c,d,e
given,
(a+b+c+d+e)/5=264
a+b+c+d+256=264*5 [since 5th day=256]
(a+b+c+d+)/4=1(320-256)/4 [dividing both side by 4]
average attendence of 4 days =266
