Answer:

To find the product of 568.32 and [tex]10^{4}[/tex], move the decimal point in 568.32 4 places to the right because [tex]10^{4}[/tex] has 4 zeros.

Step-by-step explanation:

[tex]10^{4}[/tex] = 10000

568.32 · 10000 = 5683200

the decimal point moved 4 places to the right because 10000 has 4 zeros.

Answer:

  14 ohms

Step-by-step explanation:

The resistance varies directly with length, so increasing the length by a factor will increase the resistance by the same factor.

__

The length of the wire increased by a factor of 1.4 from 100 ft to 140 ft. That means the resistance will increase by a factor of 1.4 from 10 ohms to 14 ohms. (The diameter did not change.)

The longer wire will have a resistance of 14 ohms.

multiply quantity of each and add them together to get total of 540

2s + 5c = 540 or 5c + 2s = 540

The difference in pages is 19 so you would subtract: c-s = 10

answer would be

d: c-s = 10

5c + 2s = 540

Using the areas of the rectangle and of the square, it is found that 24 unit squares will be used to tile the rectangle.

The area of a square of side l is given by the square of l, that is:

A(l) = l².

In this problem, we have that [tex]l = \frac{1}{10}[/tex], hence the area is given by:

[tex]A = \left(\frac{1}{10}\right)^2 = \frac{1}{100} = 0.01[/tex]

The area of a rectangle of length l and width w is given by the multiplication of the measures, that is:

A = lw.

In this problem, we have that the measures are:

[tex]l = \frac{3}{10}, w = \frac{4}{5}[/tex]

Hence:

[tex]A = lw = \frac{3}{10} \times \frac{4}{5} = \frac{12}{50} = \frac{24}{100} = 0.24[/tex]

The area of the rectangle is 24 times the area of the square, hence 24 unit squares will be used to tile the rectangle.

The number of unit squares with a side length  of 1/10 foot that Rhys uses to tile the rectangle is 24 units

A square is a plane shape with 4 sides

The formula for calculating the area of the square is expressed as:

A = l^2

Given

side length of a square = 1/10 foot

A = (1/10)² = 1/100 = 0.01 square foot

Determine the area of the rectangle

Area = length * width

Area = 3/10 * 4/5
Area = 12/50 = 6/25
Area = 0.24 square foot

Take the ratio of both areas

Ratio = 0.24/0.01

Ratio = 24 units

Hence the number of unit squares with a side length  of 1/10 foot that Rhys uses to tile the rectangle is 24 units

Using algebra tiles to represent the polynomial x² + 18x + 80 would be problematic due to the large number of tiles required.

Algebra tiles are mathematical manipulatives that help students better understand algebraic thinking patterns and concepts. These tiles have shown to be useful as physical examples

Using algebra tiles to represent the polynomial x² + 18x + 80 would be problematic due to the large number of tiles required.

https://brainly.com/question/22560523

Answer:

Sample response: Algebra tiles would not be a good tool to use to factor the trinomial because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles. That is a total of 99 tiles. It would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. You would also need to determine how to arrange all those tiles to make a rectangle. Since 80 is a multiple of 10, you might recognize that 10 and 8 are the factors that add to 18, which would give you the values to use in the X method.

The true statements about the figure are:

Volume = 1/3(length)(width)(height)

The volume of the composite figure = sum of the volume of each rectangular pyramids.

The two pyramids have the same height and base. Therefore:

Volume of the composite figure = 2[1/3(length)(width)(height)] = 2[1/3(9)(1.5)(5)]

Step-by-step explanation:

When multiplying by 10s, the decimal point moves. Since it is a fraction, making it lesser than an actual 10, the decimal point moves one space to the left (instead of right)

437.683

Take away 430 because we don't need it for this step

Answer:

lateral area = 1892.1 m²

Step-by-step explanation:

The lateral surface area of the square based pyramid is required.

lateral surface area = 1/2 × perimeter × slant height

we have to find the slant height using Pythagoras theorem

base = 35

height = 27.03

slant height² =  17.5² + 27.03²

slant height² = 1036.8709 + 424.36

slant height² = 1461.2

slant height = √730.61

slant height = 27.0297983714

slant height ≈ 27.03 m

lateral area = 1/2 × perimeter × slant height

lateral area = 1/2 × 35 × 4 × 27.03

lateral area = 3784.200/2

lateral area = 1892.1 m²

The additive inverse of a number gives zero. The additive inverse of the complex number -8+3i is 8-3i.

The additive inverse of a number is the other number which when added to the initial number gives the output as zero.

As we know about the additive inverse, therefore, we need a number that will return zero when added to the complex number.

The additive inverse of the complex number -8+3i will be,

[tex](-8+3i) + (8-3i) = 0[/tex]

Answer:

14 [m].

Step-by-step explanation:

1) in the square ABCD AC is diagonal, its length can be calculated as AB*√2;

2) the length of AB can be calculated:

AB=√Area(ABCD); ⇒ AB=√98;

Then

3) AC=√98*√2=14 [m].

Answer:

[tex]14\:m[/tex]

Step-by-step explanation:

ABCD is a square. (Given)

[tex] \implies \: A(square) = \overline{AB} ^{2} \\ \\ \implies \: 98 = \overline{AB} ^{2} \\ \\ \implies \: \overline{AB} = \sqrt{98} \\ \\ \implies \: \overline{AB} = \sqrt{ {7}^{2} \times 2} \\ \\ \implies \: \overline{AB} = 7\sqrt{ 2}\\\\\implies \overline{AC}= \overline{AB} \times \sqrt 2 \\\\\implies \overline{AC}= 7\sqrt{ 2} \times \sqrt 2\\\\\implies \overline{AC}= 14\: m[/tex]

Answer:

35 units ^2

Step-by-step explanation:

First, draw lines or count how many units are between each point. Don't go diagonal, just up/down or left/right, like from point B to point A.

So I counted 5 units from point B to A, 5 units from C to D, 7 units from A to D, and 7 units from B to C.

Now, you choose two sides - one that goes up/down and one that goes left/right. This is your base and your height.

So you should have 5 and 7. Now, the equation of a rectangle is base times height (b* h) so you multiply 5 and 7 together to get your answer, 35 units ^2
