Answer:

2.4 *103 = 247.2

1.5*103 = 154.5

3.6*106 = 381.6

3.9*106 = 413.4

3.6*109 = 392.4

3.9*109 = 425.1

Step-by-step explanation:

2.4 * 103

we firstly count decimal numbers

in the calculation

only 2.4 has a decimal and only one number after the point

so we keep it aside making

2.4 = 24 1 dp (decimal place)

Answer:

Step-by-step explanation:

So in our case, let assume 'x' as a common factor.

Thus,

4x + 5x + 7x = 5600;

16x = 5600;

x = 5600/16 = 350.

So,

4x= 350*4 =1400;

5x= 350*5 = 1750; &

7x= 350*7 = 2450.

Your answer is, 5600 = 1400+1750+2450 which is in ratio of 4:5:7.

Answer:

Complex roots for polynomials equations will always come in conjugate pairs.  Since 1-2i is a root, 1+2i will also be a root.  (Just switch the sign of the imaginary part to its opposite.)

Step-by-step explanation:

So far we have 1-2i and 1+2i as roots.  We need two more to make a 4th degree polynomial.

x=1 with multiplicity of 2 means that we count the root twice when we write down the polynomial: (x - 1)(x - 1) = (x - 1)2

Putting it all together, we can construct our polynomial of degree 4 as

y = f(x) = (x - 1)(x - 1)[x - (1-2i)][x - (1+2i)]

Multiply the factors (FOIL):

[x - (1-2i)][x - (1+2i)] =

x2 - (1+2i)x - (1-2i)x + (1-2i)(1+2i) =

x2 - x - 2ix - x + 2ix + (1 + 2i - 2i + 4) =

x2 - 2x + 5

(x - 1)(x - 1) = x2 - x - x + 1 = x2 - 2x + 1

Now multiply the two underlined expressions:

y = (x2 - 2x + 5)(x2 - 2x + 1)

= x4 - 2x3 + 5x2 - 2x3 + 4x2 - 10x + x2 - 2x + 5  by multiplying term by term

= x4 - 4x3 + 10x2 -12x + 5 by collecting like terms.

(a) Volume of any Pyramid =   [tex]\frac{1}{3} * (Base-Area)*height = \frac{1}{3} *220.22*9 = 660.66[/tex] cubic units

(b) Sarah doesn't have to go through all the hard work as the smaller pyramid has a ratio of 2:3 to the bigger pyramid, so we get the equation, to help us solve it.

[tex]660.66 = \frac{2}{3} *(Area-of-larger-pyramid)[/tex]

Hope that helps!

Step-by-step explanation:

(a) To calculate the volume of a pyramid, you can use the formula: V = (1/3) * B * h, where V is the volume, B is the area of the base, and h is the height of the pyramid.

In this case, Sarah has the area of the base (B) as 220.22 square units and the height (h) as 9 units. Let's substitute these values into the formula:

V = (1/3) * 220.22 * 9

V ≈ 660.66 square units

Therefore, the volume of the smaller pyramid is approximately 660.66 cubic units.

(b) No, Sarah doesn't need to go through the hard work again to find the volume of the larger pyramid. Since the two pyramids are similar, the ratio of their volumes will be equal to the cube of the ratio of their corresponding sides.

The scale factor of the smaller pyramid compared to the larger pyramid is 2:3. Since the scale factor is determined by the corresponding sides, it applies to both the base length and the height of the pyramid. Therefore, the volume of the smaller pyramid compared to the larger pyramid is (2/3)^3 = 8/27.

In other words, the volume of the smaller pyramid is 8/27 times the volume of the larger pyramid. So if Sarah already knows the volume of the smaller pyramid, she can simply multiply it by 27/8 to find the volume of the larger pyramid.

(c) To calculate the volume of the larger pyramid, we can use the ratio mentioned above:

Volume of the larger pyramid = (Volume of the smaller pyramid) * (27/8)

Volume of the larger pyramid ≈ 660.66 * (27/8)

Volume of the larger pyramid ≈ 2239.99 square units

Therefore, the volume of the larger pyramid for Sarah is approximately 2239.99 cubic units.

Answer:

A (2.5, 4 )

Step-by-step explanation:

the coordinates of A are the intersection of the 2 lines AB and AC , that is

2x + 3y = 17 → (1)

4x - y = 6 → (2)

multiplying (2) by 3 and adding to (1) will eliminate y

12x - 3y = 18 → (3)

add (1) and (3) term by term to eliminate y

14x + 0 = 35

14x = 35 ( divide both sides by 14 )

x = [tex]\frac{35}{14}[/tex] = 2.5

substitute x = 2.5 into either of the 2 equations and solve for y

substituting into (1)

2(2.5) + 3y = 17

5 + 3y = 17 ( subtract 5 from both sides )

3y = 12 ( divide both sides by 3 )

y = 4

solution is (2.5, 4 )

I'm not really sure if those are the right answers, but from what I was taught in school, I think so.

The equation that can be used to find the measure of angle LKJ  is

x = Sin⁻¹ (8.9/10.9).

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled triangle.

As we know that

sine of an angle = perpendicular/hypotenuse

Sine of ∠LKJ = 8.9/10.9

∠LKJ  = Sin⁻¹ (8.9/10.9)

x = Sin⁻¹ (8.9/10.9)

Therefore, the equation that can be used to find the measure of angle LKJ is x = Sin⁻¹ (8.9/10.9).

Answer:

88

Step-by-step explanation:

If the top layer has two​ logs, there are a total of 88 logs in the pile

Number of logs in the bottom layer = 22

Number of logs in the top layer = 2

Number of logs in each subsequent layer = 22 - 2 = 20

Number of layers in the pile = 22 - 2 + 1 = 21

Total number of logs in the pile = 22 + 20 + 18 + ... + 2

This is an arithmetic series with first term 22, last term 2, and common difference -4.

The sum of an arithmetic series is given by the following formula:

sum = (first term + last term)/2 * number of terms

sum = (22 + 2)/2 * 21 = 88

Therefore, there are a total of 88 logs in the pile.\

Answer:

Mr. Crow dimension of the lawn = 85 × 40

Area of the lawn = 3250 square feet

Step-by-step explanation:

Let x represents the width of the rectangle,

Then According to the question,

The length of the rectangle = 2 x + 5

Also it is given that the perimeter of the rectangle = 250 feet.

But we know that the perimeter of the rectangle = 2 × ( length + width)

Thus, the perimeter of the rectangle = 2( 2x+5+x) = 2(3x+5) = 6x+10

If x = 30,  the perimeter of the rectangle = 6 × 30 + 10 = 190 < 250

Thus, x ≠ 10.

If x = 50,  the perimeter of the rectangle = 6 × 50 + 10 = 310 > 250

Thus, x ≠ 50

If x  = 40, the  the perimeter of the rectangle = 6 × 40 + 10 = 250 = 250

Thus, x = 40

Therefore, the width of the rectangle, x  = 40 feet.

And, the length of the rectangle, 2 x + 5 = 2 × 40 + 5 = 85 feet.

1) The dimension of the rectangle = 85 × 40

2)The area of the rectangle = length × width = 85 × 40  = 3250 square feet.Let x represents the width of the rectangle,

Then According to the question,

The length of the rectangle = 2 x + 5

Also it is given that the perimeter of the rectangle = 250 feet.

But we know that the perimeter of the rectangle = 2 × ( length + width)

Thus, the perimeter of the rectangle = 2( 2x+5+x) = 2(3x+5) = 6x+10

If x = 30,  the perimeter of the rectangle = 6 × 30 + 10 = 190 < 250

Thus, x ≠ 10.

If x = 50,  the perimeter of the rectangle = 6 × 50 + 10 = 310 > 250

Thus, x ≠ 50

If x  = 40, the  the perimeter of the rectangle = 6 × 40 + 10 = 250 = 250

Thus, x = 40

Therefore, the width of the rectangle, x  = 40 feet.

And, the length of the rectangle, 2 x + 5 = 2 × 40 + 5 = 85 feet.

1) The dimension of the rectangle = 85 × 40

2)The area of the rectangle = length × width = 85 × 40  = 3250 square feet.

Answer: 9

Step-by-step explanation: Given The family size sunscreen bottle contains 12 fluid ounces of sunscreen. The standard bottle holds only 75% as much. The normal sunscreen container contains how many fewer fluid ounces?

A 12-ounce family-size bottle is available. However, the regular bottle contains 75% less.

So, 75/100 x 12 = 9 ounces.

Step-by-step explanation:

When working with rates, multiplication is very useful. Rate questions will give a specific rate and then a time period. They often ask, based on the rate, what can be achieved in the given time period.

The question says that if Donna can read 20 chapters in 1 hour, how many chapters can she read in 4 hours. To solve this, you can multiply 20*4; this will show how many chapters she reads in the given time period.

Since 20*4=80, she must read 80 chapters in 4 hours.

The length of the top surface is given by h(x) = 11x + 1.

Area is the amount of space occupied by a two dimensional object or figure. The area (A) of a rectangle is given by:

A = length * width

Let h(x) represent the width, hence:

66x² + 17x + 1 = (6x + 1)(11x + 1)

Since the width is g(x) = 6x + 1, hence the length = 11x + 1

The length of the top surface is given by h(x) = 11x + 1.

What is Relative Frequency?

Relative frequency is simply the number of outcomes in a particular subgroup (f) divided by the total number of outcomes in an experiment (n).

Thus, Relative frequency= f/n

In the above question, we need to find the relative frequencies of 2 subgroups- lifeguards and retail.

For lifeguards, f=3 and n=15

∴ Relative Frequency (A) = [tex]\frac{3}{15}[/tex]

Since we've to express it in percentage form,

A= [tex]\frac{3}{15}[/tex] * 100
