Julian's timed lap after 4 weeks of training written in mixed fraction form is 58 1/10 seconds.

What are fractions?

Every number of equal parts is represented by a fraction, which also represents a portion of a whole. A single object or a collection of objects might be whole. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object. The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves. The number of parts into which the whole has been divided is shown by the denominator. How many sections of the fraction are displayed or chosen is shown in the numerator.

Given,

Number of metres run Julia runs each week = 400

Time taken to run 400m dash in the beginning = 59 7/10 seconds

                                                                                = 597/10 seconds

Since the time is given in fractions, we have to do fraction subtraction for the following weeks.

Time taken in week 1 = 597/10 - 0.6 seconds = 597/10 - 6/10 = 591/10 seconds

Time taken in week 2 = 591/10 - 1/4 = 2364 - 10 / 40 = 2354/40 seconds

Time taken in week 3 = 2354/40 + 0.1 = 2354/40 + 1/10 = 2358/40

Time taken in week 4 = 2358/40 - 17/20 = 2358-34 / 40 = 2324/40

                                                                             = 581/10= 58 1/10 seconds.

Therefore Julian's timed lap after 4 weeks of training written in mixed fraction form is 58 1/10 seconds.

Answer:

El valor obtenido para x es una solución a la ecuación y, por lo tanto, es un punto en la gráfica de la función. Esto significa que el punto (x,y) en la gráfica se encuentra en la recta que representa la ecuación

Step-by-step explanation:

the values of a, m, and x will be √5, 3√5, and 2 respectively.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

Given, A big right triangle has three other right triangles in it.

Since, In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem

For the smallest right triangle,

Hypotenuse = 3

thus,

3² = 2² + a²

a² = 9 - 4

a² = 5

a = √5

For the medium size triangle,

Hypotenuse = 3 + 6 = 9

Other side = 2 + 4 = 6

Base = m

Thus,

9² = 6² + m²

m² = 81 - 36

m² = 45

m = 3√5

For the biggest triangle,

hypotenuse = 3 + 6 + 3 = 12

Height = 2 + 4 + x = 6 + x

base = 5

Since the given triangle is congruent to the smallest triangle,

(6 + x)/ 12 = 2/3

6 +x = 8

x = 2

The figure is a composite figure compromising of a rectangle OHKN, two triangles ∆LMN and ∆HJK, and a semicircle of arc HP, hence the total area will be derived by the sum of area for each basic shapes.

We can observe from the figure that the lines OL and HK are parallel, likewise the lines OH and NK, so OHKN is a rectangle and its area can be simply derived by multiplying its length by the width.

LMN and HJK are two different triangles and their area can be derived by half of the multiple of their base and height.

we will be left with a semicircle of arc HP and the area is derived using the formula πr²/2, where r is the radius.

The model of the exponential function is y = 3.40(1.86)^x

From the question, we have the following parameters that can be used in our computation:

(6, 140) and (7, 260)

The exponential function for the model can be expressed as:

y = ab^x

Where

b = 260/140

b = 1.86

So, we have

y = a(1.86)^x

Substitute the known values in the above equation, so, we have the following representation

140 = a(1.86)^6

This gives

a = 140/(1.86)^6

Evaluate

a = 3.40

This means that

y = 3.40(1.86)^x

Hence, the function is y = 3.40(1.86)^x

Answer:

Plain burgers: 12

Double cheeseburgers: 9

Regular cheeseburgers: 12

Step-by-step explanation:

Let's use P, D, and R to represent the number of plain burgers, double cheeseburgers, and regular cheeseburgers, respectively.

Each plain burger requires 1 patty and 1 bun, so we can make a maximum of 12 plain burgers (since we have 12 buns).

Each double cheeseburger requires 2 patties, 1 bun, and 2 slices of cheese, so we can make a maximum of 9 double cheeseburgers with the available patties, buns, and cheese. (We have enough patties and buns for 18 burgers, but each double cheeseburger uses twice as many patties, so we divide the total number of patties by 2 to get the maximum number of double cheeseburgers we can make.)

Each regular cheeseburger requires 1 patty, 1 bun, and 1 slice of cheese, so we can make a maximum of 16 regular cheeseburgers with the available patties, buns, and cheese (since we have 16 slices of cheese).

To maximize our sales, we want to make as many of each type of burger as we can. Since we can only make 12 plain burgers, we should make all 12 of those. We can then make 9 double cheeseburgers (using 18 patties, 9 buns, and 18 slices of cheese), and 12 regular cheeseburgers (using 12 patties, 12 buns, and 12 slices of cheese).

So the final answer is:

Plain burgers: 12

Double cheeseburgers: 9

Regular cheeseburgers: 12

Given:-

To find:-

Answer:-

The given figure is made up of a cone and a hemisphere , so to find the total volume , we would find the volume of cone and hemisphere individually and add them up to find the net volume.

Finding volume of cone:

The data we have is ,

As we know that the volume of cone is given by,

[tex]\implies V =\dfrac{1}{3}\pi r^2 h \\[/tex]

on substituting the respective values,we have;

[tex]\implies V =\dfrac{1}{3}\times 3.14 \times (9in.)^2 \times 14in .\\[/tex]

[tex]\implies V = \dfrac{1}{3}\times 3.14 \times 81in.^2\times 14in. \\[/tex]

[tex]\implies V = 1186.92 \ in.^3 \\[/tex]

Finding the volume of hemisphere:

As we know that the volume of hemisphere is given by;

[tex]\implies V =\dfrac{2}{3}\pi r^3 \\[/tex]

And here ,

So that;

[tex]\implies V =\dfrac{2}{3}\times 3.14\times (9\ in.)^3 \\[/tex]

[tex]\implies V =\dfrac{2}{3}\times 3.14\times 729\ in.^3 \\[/tex]

[tex]\implies V = 1526.04 \ in.^3 \\[/tex]

Hence the total volume will be ,

[tex]\implies V_{prop} = (1526.04 + 1186.92 )in.^3\\[/tex]

[tex]\implies V = 2712.96 \ in.^3 \\[/tex]

[tex]\implies \underline{\underline{ V_{prop}= 2713\ in.^3 }} \\[/tex]

Hence the volume of prop is 2713 in.³

and we are done!

Answer:

2713.0 in³  (nearest tenth)

Step-by-step explanation:

To calculate the volume of the prop, sum the volume of the cone and the volume of the half-sphere.

[tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a cone}\\\\$V=\dfrac{1}{3} \pi r^2 h$\\\\where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\ \phantom{ww}$\bullet$ $h$ is the height.\\\end{minipage}}[/tex]     [tex]\boxed{\begin{minipage}{4 cm}\underline{Volume of a half-sphere}\\\\$V=\dfrac{2}{3} \pi r^3$ \\\\ where:\\ \phantom{ww}$\bullet$ $r$ is the radius. \\\end{minipage}}[/tex]

Therefore, the equation for the volume of the prop is:

[tex]V_{\sf prop}=\dfrac{1}{3} \pi r^2 h+\dfrac{2}{3} \pi r^3[/tex]

From inspection of the given diagram:

Substitute the values of r, h and π into the equation and solve for V:

[tex]\begin{aligned}\implies V_{\sf prop}&=\dfrac{1}{3} \pi r^2 h+\dfrac{2}{3} \pi r^3\\\\&=\dfrac{1}{3} (9)^2 (14)+\dfrac{2}{3} \pi (9)^3\\\\ &=\dfrac{1}{3} \pi (81) (14)+\dfrac{2}{3} \pi (729)\\\\ &=378 \pi+486 \pi\\\\ &=864 \pi\\\\&=864 \cdot 3.14\\\\&=2712.96\\\\&=2713.0\;\sf in^3\;\;(nearest\;tenth)\end{aligned}[/tex]

Therefore, the volume of the prop is 2,713.0 in³ to the nearest tenth.

(Needing a bit more context but if its sequences then:)

Answer:

Let's suppose that Mr. Lee puts "x" apples into each box.

According to the first statement, when he puts an equal number of apples into 8 boxes, he has one apple left. This can be represented by the equation:

8x + 1 = n, where n is the total number of apples Mr. Lee has.

Similarly, the second statement says that when he puts the same number of apples into 5 boxes, he has 7 apples left. This can be represented by the equation:

5x + 7 = n

Now we have two equations with two unknowns (x and n). We can solve for x by setting the two equations equal to each other:

8x + 1 = 5x + 7

Subtracting 5x from both sides, we get:

3x + 1 = 7

Subtracting 1 from both sides, we get:

3x = 6

Dividing both sides by 3, we get:

x = 2

So Mr. Lee puts 2 apples into each box. To find the total number of apples he has, we can substitute x = 2 into either of the two equations we started with:

8x + 1 = 8(2) + 1 = 17

So Mr. Lee has 17 apples

We are given the following system of equations:

y = (1/2)x + 4 ---(1)

x - y = 8 ---(2)

We can solve this system of equations by substitution method.

From equation (2), we have:

x - y = 8

Solving for x, we get:

x = y + 8

Substitute this value of x in equation (1):

y = (1/2)(y+8) + 4

Simplifying and solving for y, we get:

y = 2

Now, substitute this value of y back in equation (2) to find the value of x:

x - 2 = 8

x = 10

Therefore, the solution of the given system of equations is (x, y) = (10, 2).

Step-by-step explanation:

$60÷8=$7.50

each book should of cost $7.50

To make the profit of $5000, the temperature should be 290 degrees Fahrenheit.

The general equation of a straight line is -

y = mx + c

where -

{m} is the slope of the line.

{c} is the {y} - intercept.

Given is a scatter plot as shown in the image.

We can write the equation of the line of best fit as -

{m} = (400 - 0/(60 - 40)

{m} = 400/20

{m} = 20

We can write the y - intercept as -

y = 20x + c

0 = 800 + c

c = - 800

So, the equation of the line of best fit is -

y = 20x - 800

For {y} = 5000, we can write -

5000 + 800 = 20x

5800 = 20x

x = 5800/20

x = 290

Therefore, to make the profit of $5000, the temperature should be 290 degrees Fahrenheit.
