Answer:
12565.11 teeth approximately cut cross the cutting surface per seconds.
Step-by-step explanation:
Since the diameter is 10inches, the circumference of the arm saw is 10π (circumference is πd where d is diameter).
The number of teeth on the cutting blade can be gotten by multiplying the diameter by 12 since we have 12 teeth per inch on the arm saw
Number of teeth on saw = 12 x 10π = 120π.
To get the number of teeth that cross the cutting surface in 2000rpm we multiple it by the total number of teeth in just one rpm.
So we have 2000 x 120π. But since we are asked to find it in revolution per seconds then 2000r/m = 2000r/60s ≈ 33.33
Therefore, we have
33.33 x 120π ≈ 12565.11 teeth

We can tell this is true because of the 3x in the second on and just hte x in the first. If you look closely you'll see the coefficents for the x values is the only difference between the two.
Let's now solve
We need to get a positive variable by itself
let's take x+y=5 and solve for y
x-5= -y
y= -x+5
We can then plug this y value into the other equation
3x-(-x+5)= -5
3x+x-5= -5
4x= 0
x=0
Let's then plug this value in for x into any of the beginning equations
0+y=5
y=5

A rectangles base is 2in. Shorter than twice its height. The rectangles area is 40in^2. Find it's dimensions.
Answer:
5 in by 8 in
Step-by-step explanation:
Given that :
Area, A of rectangle = 40 in²
Let
height = x
Base = 2x - 2
Area of rectangle = L * B
40 = x * (2x - 2)
40 = 2x² - 2x
2x² - 2x - 40 = 0
x² - x - 20 = 0
x² - 5x + 4x - 20 =0
x(x - 5) +4(x - 5) = 0
x - 5 = 0 or
x + 4 = 0
x = 5 or x = - 4
X cannot be negative
X = 5
Height = 5
Base = 2*5 - 2 = 8
Anna opened a savings account and deposited $300.00 as principal. The account earns 1%
interest, compounded annually. What is the balance after 2 years?
Answer:
$6
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 1%/100 = 0.01 per year,
then, solving our equation
I = 300 × 0.01 × 2 = 6
I = $ 6.00
The simple interest accumulated
on a principal of $ 300.00
at a rate of 1% per year
for 2 years is $ 6.00.

Step-by-step explanation:
After solving the given equation, the value obtained for x will be equal to -5/4.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given expression in the question,
(15x + 7) + (-11x - 2)
15x + 7 -11x - 2

Answer:
V=7065in³
Step-by-step explanation:
Radius is marked as 15, sub in 15 for r.
We are told to use 3.14 for π.
V=((4/3)πr³)/2
V=((4/3)(3.14)(15³))/2
V=((4/3)*3.14*3375)/2
V=14130/2
V=7065in³

You often go to school by bus. You have two bus systems you could take. City Bus offers a monthly pass that costs $15 and then you pay $1 per ride. Campus Transport simply charges $2.50 per ride and does not require a monthly pass. After how many rides will the total costs of the two options be the same? Write a system of equations in order to solve this problem.
Answer:
For City Bus you will need to ride 10 times for 2 months, and for Campus Transport you need to ride 16 times.
Step-by-step explanation:
$2.50 x 2 = $5.00 so you know that the number of rides needs to even in order to have a whole number. This is because there is no way the City Bus cost will ever have cents.
$2.50 x 16 = $40.00
$15 x 2 = $30
$1 x 10 = $10
$30 + $10 = $40
So (15 x 2) + (10 x 1) = 16 x 2.50

Hi! Could you help me me out and solve these two problems? "eight less than the product of seven and xxx", and "the sum of six and the product of three and d". Thank you!
Given:
The given statement are:
a. Eight less than the product of seven and x.
b. The sum of six and the product of three and d.
To find:
The expression for the given statements.
Solution:
a.
Product of 7 and x is 7×x = 7x.
Eight less than the product of seven and x is 7x - 8.
Therefore, the required expression for the statement "Eight less than the product of seven and x" is 7x-8.
b.
Product of 3 and d is 3×d = 3d.
The sum of six and the product of three and d is 6+3d.
Therefore, the required expression for the statement "The sum of six and the product of three and d" is 6+3d.

In a holiday resort, the ratio of men to women is 5:6 and the ratio of
women to children is 4:7. There are 200 men staying at the resort. How
many children are there?
Answer:
Men: 5 : 3 = 20 : 12
Women: 7 : 4 = 21 : 12
So for every 12 children there are 20 men to 21 women.
Neither men nor women compose more than half of the concert population
There are 200 men staying at the resort. Then the number of children in the resort will be 292.
What are ratio and proportion?A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.
In a holiday resort, the ratio of men to women is 5:6 and the ratio of women to children is 4:7.
There are 200 men staying at the resort.
Then the number of women in the resort will be
Women / 200 = 5 / 6
Women = 500 / 3
Then the number of children in the resort will be
(500/3) / children = 4/7
children = 291.67
children ≈ 292
