what is the quotient of 84/0.729

The correct way to write 0.0000250 m in scientific notation is 2.5 · 10⁻⁵ m.

Scientific notation is a convenient way to write numbers that are very large or very small. A number written in scientific notation consists of a number greater than or equal to 1 but less than 10 multiplied by a power of 10. Here are some examples of numbers written in scientific notation:

Since you're given a number less than 1, move the decimal point to the right until you have a number between 1 and 10. Then, count the number of times you moved the decimal and write that as negative exponent over a base of 10. Finally, write out number multiplied by the power. You'll get 2.5 · 10⁻⁵ if you do those things correctly.

The car use 6.67 liters of petrol to travel 160 miles of distance.

Given, the car use the same amount of petrol for each mile it travels.

A car use 55 liters of petrol to travel 495 miles.

we have to find the petrol used to travel 160 miles.

As, 55 liters = 495 miles

495 miles = 55 liters

1 mile = 55/495 liters

Now, 160 miles = 55/495×160 liters

160 miles = 6.67 liters

So, the car use 6.67 liters of petrol to travel 160 miles of distance.

Hence, the car use 6.67 liters of petrol to travel 160 miles of distance.

The vertex form of the function g(x)= 2[tex]x^2[/tex]+16x+6 is g(x)= 2[tex](x+4)^2[/tex]-26.

What is vertex form of the function?

   The function's maximum or lowest possible output is represented by the vertex of the quadratic function's graph. When viewing a graph, the vertex is the highest or lowest point on the parabola. Utilizing the vertex formula is the simplest technique to discover the vertex. It is simple to locate the vertex of the parabola using the vertex form of a quadratic equation. Y=a(xh)2+k is the definition of the generic vertex form, where h is the x-coordinate and k is the y-coordinate of the vertex.

Here the given function is ,

=> g(x) = 2[tex]x^2[/tex]+16x+6

=> g(x) = 2([tex]x^2+[/tex]8x+3)

=> g(x) = 2([tex]x^2+[/tex]8x+16-16+3)

=>g(x) = 2 [[tex](x+4)^2[/tex]-13]

=> g(x)=  2[tex](x+4)^2[/tex]-26

Therefore vertex form of the function is g(x)= 2[tex](x+4)^2[/tex]-26 and vertex is (-4,-26).

The rate per minute at which Karama can paint banisters is 0.02.

In the given question,

Karama can paint a staircase banister in 50 minutes.

We have to find the rate per minute at which Karama can paint banisters.

Since we have to find the rate per unit. Rate per unit means how much Karama can paint in one minute.

To find the rate per unit we divide 1 by 50.

As we know that Karama can paint one staircase banister in 50 minute.

So we can write it as

50 minute = 1 staircase banister paint

Now in 1 minute.

1 minute = 1/50 staircase banister paint

Simplifying

1 minute = 0.02 staircase banister paint

The perimeter of the figure is 32 cm

The figure represents the given parameters

On the figure, we have the lengths of the side lengths to be:

Lengths = 7 cm, 5 cm, 3 cm, 4 cm, 4 cm, 9 cm

To determine the perimeter of the shape, we simply add the side lengths

Mathematically, this can be represented as

Perimeter = Sum of side lengths

Substitute the known values in the above equation So, we have the following equation

Perimeter = 7 cm + 5 cm + 3 cm + 4 cm + 4 cm + 9 cm

Evaluate the sum

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Brown rice: $2.00 per pound

So, the equations are:

x + y= 17

2x+ 4.5y= 54

2( 17- y) + 4.5y= 54
