There are 50 odd integers from 1 to 100.

Odd integers  are the numbers that cannot be divided by 2 evenly. It cannot be divided into two separate integers evenly. If we divide an odd integer by 2, then it will leave a remainder. In other words, numbers in the form of [tex]2k + 1[/tex], where [tex]k[/tex] ∈ [tex]Z[/tex] (i.e. integers) are called odd numbers.

First odd number is 1 from 1 to 100.

Last odd number is 99 from 1 to 100.

Total odd numbers = 99+1 ÷ 2 = 50

The amount of salt in the tank at the end of one hour is 103 lbs .

Given

Initially there are 100 gal in the tank. There are 6 lbs of salt. The concentration of salt in the tank is 6/100 or 0.06 lbs per gal.

Water flowing in has concentration of 1 lb/gal.

Water flowing out has unknown concentration because mixture is constantly changing.

Tank is losing 1 gal per minute. ( 2 - 2 = 0 )

V ( t ) = 100 - t

s ( t ) = 6 + 2t − 3t ∗ C( t )

C ( t ) = s ( t ) / V ( t )

= 100 - t / 2t − 2t ∗ C( t )

= 6 + 2t / 100 + 2t

After 60 minutes

C ( t ) = 6 + 2 * 60 / 100 + 2 * 60

= 6 + 120 / 100 + 120

= 126 / 220

= 63 / 110

Salt content s( t ) = 6 + 2 * 60 - 3 * 60 * 63 / 110

= 126 - 180 * 63 / 110

= 126 - 103

Both were multiplied by 100 and the quotient of both expressions is 2.5.

What are arithmetic operations?

Arithmetic operations is a branch of mathematics that studies numbers and the operations on numbers that are useful in all other branches of mathematics. It consists primarily of operations like addition, subtraction, multiplication, and division.

We have,

3.75 ÷ 1.50 is equivalent to 375 ÷ 150.

Moving the decimal point 2 places to the right is equivalent to multiplication by 100.

so, both were multiplied by 100.

The quotient is:

3.75 ÷ 1.50 = 2.5

375 ÷ 150 = 2.5

Hence, both were multiplied by 100 and the quotient of both expressions is 2.5.

Answer:

Step-by-step explanation:

To find the time it takes for the rock to hit the water, we need to find the value of t when h is equal to zero. This is because the rock will hit the water when it reaches a height of zero feet above the water.

Substituting zero for h in the equation h = -16t^2 + 12t + 40, we get:

0 = -16t^2 + 12t + 40

This equation is a quadratic in t, so we can use the quadratic formula to solve for t:

t = (-12 +/- sqrt(12^2 - 4 * (-16) * 40)) / (-32)

Simplifying, we get:

t = (-12 +/- sqrt(144 + 640)) / (-32)

t = (-12 +/- sqrt(784)) / (-32)

t = (-12 +/- 28) / (-32)

t = -40/-32 or t = 16/-32

t = 1/8 or t = -1/2

Since the time cannot be negative (because the rock was thrown upwards), the only solution that makes sense is t = 1/8 seconds.

Therefore, it will take 1/8 seconds for the rock to hit the water.

It becomes

[tex]$$\begin{aligned}5: 8: & 6.5: x \\5 \times x & =8 \times 6.5 \\x & =\frac{8 \times 6.5}{5} \\x & =\frac{52}{5} \\x & =10.4\end{aligned}$$[/tex]

Therefore,

5 machines will take $10.4$ hour to produce the same number of parts.

Equivalent interest rates are interest rates that produce the same future value after one year. For example, 10% compounded quarterly and 10.125% compounded semiannually are equivalent nominal interest rates.

Step-by-step explanation:

The formula for the sum of the interior angle measures of a polygon with n sides is (n - 2)180 degrees.

The value of the discriminant for 2x² + 5x + 7 = 0 is -31.

The discriminant of a quadratic equation is the part of the equation used to determine the number and type of solutions. It is calculated by subtracting 4 times the coefficient of the squared term, a, from the coefficient of the linear term, b, squared. This is then divided by four times the coefficient of the squared term, a.

In this case, the equation is 2x² + 5x + 7 = 0.

The discriminant for this equation is calculated as follows:

Discriminant = b² - 4ac

Discriminant = (5)² - 4(2)(7)

Discriminant = 25 - 56

Discriminant = -31

Therefore, the value of the discriminant for 2x² + 5x + 7 = 0 is -31.

Step-by-step explanation:

The solid shape is composed of a cone and a hemisphere.

Let's work out the radius of the cone since the hemisphere and the cone share the same radius.

Let the radius be r cm.

Volume of cone= [tex] \displaystyle{\frac{1}{3} \pi {r}^{2} h}[/tex]

Substituting the volume and height of the cone:

[tex]270\pi = \displaystyle{\frac{1}{3} (\pi)( {r}^{2} )(10)}[/tex]

Simplify:

[tex] \frac{10}{3} {r}^{2} = 270[/tex]

[tex]81 = {r}^{2} [/tex]

Square root both sides:

[tex]r = \sqrt{81} [/tex]

r= 9

The volume of a hemisphere is half the volume of a sphere.

Volume of hemisphere

[tex] = \displaystyle{ \frac{1}{2}( \frac{4}{3} )(\pi )( {r}^{3}) }[/tex]

[tex] = \displaystyle{ \frac{2}{3}\pi {r}^{3} }[/tex]

When X=3 a polynomial has a value of 61 and when X=3 a value of 143.

Given that,

Let p(x)=3x²−4x²+7x−5 is our polynomial.

Polynomials are algebraic expressions made up of coefficients and variables. Occasionally, variables are referred to as indeterminates. For polynomial expressions, addition, subtraction, multiplication, and positive integer exponents are all possible; however, division by variable is not. x2+x-12 is an illustration of a single-variable polynomial. Three terms are involved in this example: x2, x, and -12.

Substitute x=3 in above expression,

∴p(3)=3(3) 3−4(3) 2 +7(3)−5

=3(27)−4(9)+21−5

=81−36+21−5

=61

Now,

p(−3)=3(−3)

3 −4(−3) 2 +7(−3)−5

=3(−27)−4(9)−21−5

=−81−36−21−5

=−143

Answer:

136

Step-by-step explanation:

because 32 times 4 is 128 and 32 divided by 4 is 8 that together is 136 its dived by four because 15 is 1/4 of 60 which is an hour

Answer: 136 copies in 4 minutes and 15 seconds

Step-by-step explanation:

First, we need to find how many copies the machine makes per second

a minute has 60 seconds. Divide the number of copies made per minute by 60

32/60

simplify

8/15

It can make 8/15 copies per second.

It takes a minute to print 32 copies, so multiply the number of copies per minute by 4 minutes

32*4=128

128 copies in 4 minutes

now 8/15 * 15 =120/15 = 8

128+8=136
