Answer:

The skaters are 2.5 feet apart

Step-by-step explanation:

Firstly, please check attachment for diagrammatic representation.

To calculate the distance apart, this is same as the length PJ

To calculate this length, we can use the cosine rule as follows;

O^2 = P^2 + J^2 -2(P)(J)Cos 15

O^2 = 7^2 + 5^2 -2(7)(5)Cos 15

O^2 = 49 + 25 - 70Cos15

O^2 = 74 - 67.61

O^2 = 6.39

O = √6.39

O = 2.53

O = 2.5 feet to the nearest tenth of a foot

The distance between the skaters is 2.5m

Data;

To solve this problem we can use cosine rule for this since we have the value of two sides and an angle.

[tex]c^2 = a^2 + b^2 -2ab cos C[/tex]

Let's substitute the values into the formula

[tex]c^2 = 5^2 + 7^2 - 2*5*7*cos15\\c^2 = 25 + 49 - 67.61\\c^2 = 6.39\\c = \sqrt{6.39} \\c = 2.5m[/tex]

The distance between the skaters is 2.5m

Step-by-step explanation:

Final answer:

A graph that displays a collection of ordered pairs is known as a scatter plot, which shows the relationship between two variables using a Cartesian coordinate system.

Explanation:

A graph that displays a collection of ordered pairs is called a scatter plot. A scatter plot, also known as a scatter diagram, uses Cartesian coordinates to display values for two variables. It is a pictorial representation of the relationships of quantitative data, presenting individual points where the value of one variable determines the position on the horizontal axis (x-axis), and the value of the other variable determines the position on the vertical axis (y-axis). The pattern of these points on the graph helps to visualize any correlation between the variables being analyzed.

Step-by-step explanation:

Answer: 8

Step-by-step explanation:

The correct answer is:

The volume of the pyramid is approximately 111.5 cubic inches, rounded to the nearest tenth of a cubic inch.

To find the volume of a pyramid, we can use the formula:

[tex]\[ \text{Volume} = \frac{1}{3} \times \text{Base Area} \times \text{Height} \][/tex]

Given:

- Side length of the square base = 6.6 inches

- Height of the pyramid = 7.7 inches

First, let's find the area of the square base:

[tex]\[ \text{Area of square base} = \text{Side length}^2 \]\[ = 6.6^2 \]\[ = 43.56 \text{ square inches} \][/tex]

Now, substitute the values into the formula for the volume of a pyramid:

[tex]\[ \text{Volume} = \frac{1}{3} \times 43.56 \times 7.7 \]\[ \text{Volume} = \frac{1}{3} \times 334.632 \]\[ \text{Volume} = 111.544 \text{ cubic inches} \][/tex]

Rounding to the nearest tenth, the volume of the pyramid is approximately [tex]\( \boxed{111.5} \)[/tex] cubic inches.

The volume of the square-based pyramid is calculated using the formula for the volume of a pyramid, resulting in approximately 111.8 cubic inches after rounding to the nearest tenth.

The volume of a pyramid with a square base is calculated using the formula V = (1/3) x base area x height. First, calculate the base area, which is the side length squared. In this case, the base area is:

6.6 in x 6.6 in = 43.56 in²

Then, multiply the base area by the height and divide by 3 to find the volume:

V = (1/3) x 43.56 in² x 7.7 in
= 43.56 in² x 2.566 in
= 111.804 in³, which rounds to 111.8 in³ to the nearest tenth.

Therefore, the volume of the square-based pyramid is 111.8 in³.

Answer:

0.65

Step-by-step explanation:

To get 13/20 to a decimal, the denominator needs to be multiplied by 5 to make it 100. If you multiply the denominator, you also have the multiply the numerator to make it equal. 13 x 5 is 65. The fraction is 65/100, which is 0.65 in decimal form.

13/20 as a decimal is 0.65.

To write 13/20 as a decimal, you can follow the hint provided.

First, we need to find a factor that will make the denominator 100. In this case, multiplying the denominator by 5 will give us 100.

So, we need to multiply both the numerator and the denominator of 13/20 by 5:

13/20 x 5/5 = 65/100

Now, we have 65/100 as the fraction.

To convert it to decimal form, divide the numerator by the denominator:

65 ÷ 100 = 0.65

Therefore, 13/20 as a decimal is 0.65.

This question is incomplete because the diagram of the sphere was not shown. Find attached to this answer the diagram for the sphere.

Answer:

a) The correct volume of the sphere = 113cm³

b) b) Hal's likely error was that

i) He used the wrong formula which is Surface area of the sphere(4πr²) in his calculation instead of the right formula which was the Volume of a Sphere(4/3πr³)

ii) In addition to using the wrong formula, Hal did not use π in his calculation.

Step-by-step explanation:

a) The Volume of a Sphere = 4/3πr³

From the attached diagram, the radius of the sphere was given as = 3cm

π = 3.14

The volume of the sphere = 4/3 × 3.14 × 3³

= 113.04 cm³

We were told to round up to the nearest hundredth. Therefore, correct the volume of the sphere = 113cm³.

b) Hal's likely error was that

i) He used the wrong formula which is Surface area of the sphere(4πr²) in his calculation instead of the right formula which was the Volume of a Sphere(4/3πr³)

ii) In addition to using the wrong formula, Hal did not use π in his calculation.

This means:

Surface Area of a Sphere = 4πr²

But Hal's used = 4r²

Answer:

L = 17 m W = 12 m

Step-by-step explanation:

Here is the answer.

The width of the rectangle is 12 meters, and the length is 17 meters, obtained by setting up equations based on the perimeter and the given relationship between length and width.

To find the length and width of the rectangle, we need to set up equations based on the given information. The question states that the length is 5m longer than the width, and the perimeter is 58m. Let's denote the width as w and the length as l. According to the problem, l = w + 5m.

The formula for the perimeter P of a rectangle is P = 2l + 2w. We can substitute the expression for the length into this formula:

P = 2(w + 5m) + 2w

Since we know the perimeter is 58m:

58m = 2(w + 5m) + 2w

58m = 2w + 10m + 2w

58m = 4w + 10m

48m = 4w

w = 12m

Now we can find the length:

l = w + 5m

l = 12m + 5m

l = 17m

The width of the rectangle is 12 meters and the length is 17 meters.

Answer:

The age of the spear head is of 1938 yers.

Step-by-step explanation:

The amount of carbon 14 after years is given by the following equation:

[tex]Q(t) = Q(0)e^{-rt}[/tex]

In which Q(0) is the initial amount and r is the decay rate.

The half life of carbon 14 is 5700 years.

This means that [tex]Q(5700) = 0.5Q(0)[/tex]

So

[tex]Q(t) = Q(0)e^{-rt}[/tex]

[tex]0.5Q(0) = Q(0)e^{-5700r}[/tex]

[tex]e^{-5700r} = 0.5[/tex]

[tex]\ln{e^{-5700r}} = \ln{0.5}[/tex]

[tex]-5700r = \ln{0.5}[/tex]

[tex]5700r = -\ln{0.5}[/tex]

[tex]r = -\frac{\ln{0.5}}{5700}[/tex]

[tex]r = 0.00012160476[/tex]

So

[tex]Q(t) = Q(0)e^{-0.00012160476t}[/tex]

We have to find:

t for which Q(t) = 0.79Q(0). So

[tex]Q(t) = Q(0)e^{-0.00012160476t}[/tex]

[tex]0.79Q(0) = Q(0)e^{-0.00012160476t}[/tex]

[tex]e^{-0.00012160476t} = 0.79[/tex]

[tex]\ln{e^{-0.00012160476t}} = \ln{0.79}[/tex]

[tex]-0.00012160476t = \ln{0.79}[/tex]

[tex]0.00012160476t = -\ln{0.79}[/tex]

[tex]t = \frac{-\ln{0.79}}{0.00012160476}[/tex]

[tex]t = 1938.43[/tex]

Answer:

f(x) = x^2 - 12x + 20

Step-by-step explanation:

If 10 and 2 are zeros, then (x - 10) and (x - 2) are factors of the quadratic.

Multiplying these factors together, we get

f(x) = x^2 - 12x + 20

The quadratic function with zeros at 10 and 2 is f(x) = (x - 10)(x - 2) which simplifies to f(x) = x² - 12x + 20.

Given that the zeros of a quadratic function are 10 and 2, we can write the function as f(x) = a(x - 10)(x - 2). Here, a is a non-zero coefficient. For simplicity, we can choose a as 1. This gives us the function as f(x) = (x - 10)(x - 2).

Expanding this gives us: f(x) = x² - 12x + 20.

This function represents a quadratic equation that zeros at x = 10 and x = 2. Such a function can be represented on a graph with f(x) and x as axes. The roots, 10 and 2, will be the x-coordinates at which the graph intersects the x-axis.

base(height)(1/2) = 3 x 3 x 1/2 = 4.5

The letters in the word D-I-N-O-S-A-U-R can be arranged in 40,320 ways.

To find the number of ways the letters in the word D-I-N-O-S-A-U-R can be arranged, we can use the concept of permutations.

The word D-I-N-O-S-A-U-R contains 8 different letters. To find the number of arrangements, we can use the formula for calculating permutations of n objects taken all at a time, which is n!. In this case, n is equal to 8, so the number of arrangements is 8!.

However, there are some repeated letters in the word D-I-N-O-S-A-U-R.

The letter 'A' is repeated twice. To account for the repetition, we divide the total number of arrangements by the factorial of the number of times each repeated letter occurs.

In this case, 'A' appears twice, so we divide by 2!. So the final answer is 8! / 2!.

Simplifying the expression, we have 8! / 2! = 40,320.

Step-by-step explanation:

Given that there are 30 students in class 10R and the mean marks for the entire class was 70%. Therefore, total mark of class = 70 x 30 = 2100

Given that there are 20 boys in the class and the mean marks for the boys was 62 %. Therefore, total mark of boys = 62 x 20 = 1240

To calculate the mean mark for the girls we need to find the total number of girl and total mark of girls. total number of girl = 30 - 20 (boys) = 10 total mark of girls = total mark of class -  total mark of boys = 2100 - 1240 = 860 mean mark for girls = 860 / 10 = 86
