310 = 300 + 10.
Joe will write two numbers to form 310.
Step-by-step explanation:
The expanded form is used to write numbers and see the math value of individual digits. So, the numbers are separated into individual place values and decimal places and form a mathematical expression.
310 in expanded form is 300 + 10 = 310.
find the Factor of 6x 2 - 17x + 5.
Answer:
Step-by-step explanation:
[tex]6x^2-17x+5[/tex]
This can be written as
[tex]6x^2-15x-2x+5[/tex]
Because -15-2=-17 and also (-15)(-2)=30
so now we have two pairs
[tex](6x^2-15x)+(-2x+5)[/tex]
Take out GCF from each pair
[tex]3x(2x-5)-1(2x-5)[/tex]
since (2x-5) is now the common factor so final factored form
[tex](3x-1)(2x-5)[/tex]
A truck with 32-inch diameter wheels is traveling at 60 mi/h. Find the angular speed of the wheels in rad/min. How many revolutions per minute do the wheels make?
The angular speed of the wheel is 3960 rad/min and the revolutions per minute is 630 rpm.
The velocity of the truck is 60 mph. We need to convert this speed to inches per minute.
1 mile = 63360 in, 1 hour = 60 minutes
Hence:
60 mph = (60 mile * 63360 in/mi) / (1 hr * 60 min/hr) = 63360 in/min
The diameter = 32 in, hence radius = 32/2 = 16 in
The angular speed = 63360 in/min ÷ 16 in = 3960 rad/min
Revolution per minute = 3960 rad/min ÷ 2π = 630 rpm
Hence the angular speed of the wheel is 3960 rad/min and the revolutions per minute is 630 rpm.

The wheels make approximately 52.55 revolutions per minute.
To find the angular speed of the wheels in radians per minute, we first need to find the linear speed of a point on the edge of the wheel.
The formula to calculate the linear speed (v) is given by:
[tex]\[ v = r \times \omega \][/tex]
Where:
- v is the linear speed,
- r is the radius of the wheel, and
- [tex]\( \omega \)[/tex] is the angular speed in radians per second.
Given that the diameter of the wheels is 32 inches, the radius (r ) is half of the diameter, so [tex]\( r = \frac{32}{2} = 16 \)[/tex] inches.
We are given the speed of the truck, v = 60 mi/h. To convert this to inches per minute, we need to convert miles to inches and hours to minutes:
[tex]\[ 60 \text{ miles/h} = 60 \times 5280 \text{ inches/60 minutes} = 5280 \text{ inches/minute} \][/tex]
Now, we can rearrange the formula to solve for [tex]\( \omega \):[/tex]
[tex]\[ \omega = \frac{v}{r} \][/tex]
Substituting the known values:
[tex]\[ \omega = \frac{5280 \text{ inches/minute}}{16 \text{ inches}} \]\[ \omega = 330 \text{ radians/minute} \][/tex]
So, the angular speed of the wheels is 330 radians per minute.
Now, to find the number of revolutions per minute (rpm), we need to convert the angular speed from radians per minute to revolutions per minute. Since [tex]\( 2\pi \)[/tex] radians is equal to one revolution, we have:
[tex]\[ \text{Revolutions per minute (rpm)} = \frac{\omega}{2\pi} \][/tex]
Substituting the value of [tex]\( \omega \):[/tex]
[tex]\[ \text{rpm} = \frac{330}{2\pi} \]\[ \text{rpm} \approx \frac{330}{6.28} \approx 52.55 \][/tex]
So, the wheels make approximately 52.55 revolutions per minute.

The implicit equation for the plane passing through the point (5,0,5) that is perpendicular to the line l(t)=⟨3,−1−5t,−1−2t⟩ is 3x - 5y - 2z = 20.
Explanation:To find the equation of the plane passing through the point (5,0,5) and perpendicular to the line l(t)=⟨3,−1−5t,−1−2t⟩, we need to find the normal vector of the plane. The normal vector is the direction vector of the line, which is (3, -5, -2). Using the formula for the equation of a plane in standard form, which is ax + by + cz = d, and substituting the coordinates of the point and the normal vector, we get 3x - 5y - 2z = 20
as the implicit equation for the plane.

The width of the rectangle is 3 inches less than twice the length, which is represented by L. The algebraic expression for the width is W = 2L - 3.
The width of a rectangle is described in the problem as being 3 inches less than twice the length of the rectangle. If the length of the rectangle is denoted by L, the algebraic expression to represent the width (W) can be written as:
W = 2L - 3
To clarify, this expression means that whatever the length L is, you would double it (that's the 2L part), and then subtract 3 inches to find the width of the rectangle.

Complex numbers are often used when dealing with alternating current (AC) circuits. In the equation V = IZ, V is voltage, I is current, and Z is a value known as impedance. If V = 1+i and Z=2-i, find I. Please do this quickly!!
Final answer:
The current I in the AC circuit equation V = IZ is found by complex division and is equal to 1/5 + 3/5i when V = 1+i and Z=2-i.
Explanation:
To find the current I in the equation V = IZ where V = 1+i and Z=2-i, we need to solve for I using complex division. This process involves conjugating the denominator and then performing standard multiplication of complex numbers.
Step-by-step solution:
Write down the given values in the equation: V = 1+i, Z = 2-i.Use the formula I = V / Z.Conjugate the denominator Z, which gives 2+i.Multiply the numerator and denominator by the conjugate of the denominator:So, I = (1+i) * (2+i) / ((2-i) * (2+i)).Simplify both numerator and denominator: numerator becomes 2 + 3i + i^2, and the denominator becomes 4 - i^2.Substitute i^2 with -1 and simplify: numerator becomes 2+3i-1, and the denominator becomes 4+1.The final result is I = (1+3i) / 5.Divide both the real and imaginary parts by 5: I = 1/5 + 3/5i.Therefore, the current I is 1/5 + 3/5i.
Charlie has the utility function u(xa, xb) =xaxb.his indifference curve passing through 32 applesand 8 bananas will also pass through the point where he consumes 4 apples and
Final answer:
To find the indifference curve passing through 32 apples and 8 bananas, we can set up a system of equations and solve for the relationship between apples and bananas. The indifference curve will also pass through the point where Charlie consumes 4 apples and 2 bananas.
Explanation:
An indifference curve represents a set of choices that have the same level of utility. In this case, Charlie's utility function is u(xa, xb)=xaxb. To find the indifference curve passing through 32 apples and 8 bananas, we can set up a system of equations. If we plug in these points into the utility function, we get 32a*8b=4a*xb. Solving for b, we find that b=1/2a. This means that for every amount of apples, Charlie wants to consume half as many bananas to maintain the same level of utility. Therefore, the indifference curve passing through 32 apples and 8 bananas will also pass through the point where he consumes 4 apples and 2 bananas.

All the digits are odd. The last two digits add to make ten. The first and last digits add to make eight. The first two digits add to make twelve. What is the number?
The number that fits all the given criteria is 3955, where all digits are odd, the last two add to 10, the first and last to 8, and the first two to 12.
To find a number where all digits are odd, the last two digits add up to make ten, the first and last digits add up to eight, and the first two digits add up to twelve, we can use a process of elimination and reasoning.
The last two digits must be 5 and 5 because these are the only odd digits that add up to 10.The first and last digit must be 3 and 5 respectively because these add up to 8.Since the first digit is 3 and we need the first two digits to add to 12, the second digit has to be 9.Therefore, the number is 3955.

Solve for a 6(a+3)=18+6a
The equation 6(a+3) = 18+6a is an identity after canceling out like terms on both sides, which implies that the solution for 'a' is all real numbers.
To solve for a in the equation 6(a+3) = 18+6a, we begin by expanding the left side of the equation:
6a + 18 = 18 + 6a
We notice that there are terms on both sides of the equation that can be cancelled out. The 6a on the left side can be subtracted from both sides, as well as the constant 18.
After cancelling out these terms, we are left with:
0 = 0
This equation suggests that the original equation is an identity, meaning that the value of a can be any real number, as the original equation holds true for all values of a.
