Answer:

Step-by-step explanation:

The correct fraction is simply 30/7, where 30 is the distance in miles and 7 is the number of days to complete it.

30/7 = 4.286miles daily but since you've asked to have this as a fraction, 30/7miles is good.

Final answer:

To achieve his goal of running 30 miles in a week, Raul should run 30 miles divided by 7 days, which is approximately 4 2/7 (⅔) miles every day.

Explanation:

If Raul wants to run 30 miles this week and he wants to run the same number of miles each day, we need to divide the total miles by the number of days in a week. There are 7 days in a week, so we will divide 30 miles by 7 days.

Using division: 30 miles ÷ 7 days = ⅔ miles per day. The fraction ⅔ represents the number of miles Raul plans to run each day to meet his goal of running 30 miles in a week.

Based on the number of people dying from both causes and their relationship with each other, we can calculate that the number of people dead from cancer was 300,000 and those from accidents was 60,000.

Assuming x number of people died from accidents, the number that died from cancer would be 5 times that:

= 5x

The number of people dead from accidents is:

360,000 = 5x + x

6x = 360,000

x = 60,000 people

The number dead from cancer is:

= 5x

= 5 × 60,000

= 300,000 people

In conclusion, 60,000 died from accidents and 300,000 people died from cancer.

Final answer:

To solve the problem, we created two equations: c = 5a and c + a = 360,000. After substituting and solving these equations, we found that 300,000 people died from cancer and 60,000 from accidents.

Explanation:

The question refers to a situation where the number of people dying from cancer is five times the number who died from accidents, and the total deaths from these two causes amounted to 360,000. To solve this, we can set up a system of equations. Let ‘c’ be the number of cancer deaths and ‘a’ the number of accident deaths. We are given:

Substituting the first equation into the second, we get:

Then we substitute the value of ‘a’ back into the first equation to find ‘c’:

Therefore, 60,000 people died from accidents and 300,000 from cancer.

The formula for calculating  equation of line with two points is given as :

[tex]\frac{y-y_{1}}{x-x_{1}}[/tex] = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]x_{1}[/tex] = -12

[tex]x_{2}[/tex] = 6

[tex]y_{1}[/tex] = 14

[tex]y_{2}[/tex] = -1

substituting the values into the formula , we have

[tex]\frac{y-14}{x-(-12)}[/tex] = [tex]\frac{-1-14}{6-(-12)}[/tex]

[tex]\frac{y-14}{x+12}[/tex] = [tex]\frac{-15}{18}[/tex]

[tex]\frac{y-14}{x+12}[/tex] = [tex]\frac{-5}{6}[/tex]

Answer:

Jason is 14 year old.

Step-by-step explanation:

Given: Joe, John and Jason are each a year apart in age.

           Sum of their age is 39.

Lets assume the age of Joe be x

∴ Age of Jahn will be [tex](x+1)[/tex]

And age of Jason will be [tex](x+2)[/tex]

Now, putting up an equation for the sum of their age.

∴ [tex]x+(x+1)+(x+2)= 39[/tex]

Opening the parenthesis.

⇒[tex]x+x+1+x+2= 39[/tex]

⇒[tex]3x+3= 39[/tex]

Subtracting both side by 3

⇒ [tex]3x= 36[/tex]

Dividing both side by 3

⇒[tex]x= \frac{36}{3}[/tex]

∴ [tex]x= 12\ years[/tex]

Hence, Joe is 12 year old.

Next subtituting the value of x to find age of Jason and John.

Jason= [tex](x+2)= 12+2[/tex]

∴Jason= 14 years.

John age= [tex](x+1)= 12+1[/tex]

∴ John Age= 13 years.

Hence, Jason is 14 year of age.

Answer:

x = 8

y = 10

Step-by-step explanation:

We are given the equations;

-3x + 4Y = 16

3x - y =14

We are required to solve the two equations simultaneously using elimination

In this case, we will eliminate one unknown;

We eliminate x by adding the two equations;

That is;

-3x + 4Y = 16

3x - y =14

.............................

     3y = 30

       y = 10

Solving for x

3x - (10) = 14

3x = 14 +10

  3x = 24

   x = 8

Therefore, the solution of the equation is x=8 and y=10

Answer:

9 3/4, 9 3/4, 9.5, 9.125

Step-by-step explanation:

*I converted to decimal form*

9 3/4= 9.75

9.75 is greater than both 9.5 and 9.125, so therefore it is first on the list.

Next, since 9.5 is greater than 9.125, it is arranged next on the list.

9.125 is the only number left, and is clearly the smallest out of all of the numbers shown.

We want to order the given set of numbers from greatest to lest.

The correct order is:

{9 3/4, 9 3/4, 9.5, 9.125}

Let's see how to get that.

The given set is:

{9.5, 9 3/4, 9.125, 9 3/4}

Here we can see that we have two times the mixed number (9 3/4).

This can also be written as:

9 + 3/4

And we know that 3/4 = 0.75

Then:

9 + 3/4 = 9.75

Then the mixed number is the largest number.

Then comes the 9.5, and finally the 9.125

Then the correct order is:

{9 3/4, 9 3/4, 9.5, 9.125}

Answer:

Square root of 8.

Step-by-step explanation:

Given:

Number given : 2 to the power of 3 over 2 equal ...

Using the laws of exponent:

We know that:

⇒ [tex]\sqrt{a} = (a)^1^/^2[/tex]  and

⇒ [tex]\sqrt[3]{a}=(a)^1^/^3[/tex]

So,

According to the question:

2 to the power of 3 over 2  = [tex](2) ^3^/^2[/tex]

Using fractional exponent concept where :  [tex]\sqrt[y]{a^x} = (a)^x^/^y[/tex]

This can be re-written as:

⇒ [tex](2^3)^1^/^2[/tex] and [tex]\sqrt{2^3}[/tex] that is equivalent to [tex]\sqrt{8}[/tex]    as  ...[tex]2^3=2\times 2\times 2=8[/tex]

Square root of 8 is our final answer.

Answer:

Explanation:

The ball is dropped from a height of 900 centimeters.

Since the heights form a geometric sequence, you can find a common ratio between consecutive terms. This is:

Hence, the ratio of the geometric sequence is 0.7, and taking bounce 1 as the start of the sequence, the general term of the sequence is:

            [tex]a_n=800(0.7)^{n-1}[/tex]

With that formula you can find any term:

             [tex]n=1,a_1=800(0.7)^{(1-1)}=800(0.7)^0=800\\ \\ n=2,a_{2}=800(0.7)^{(2-1)}=800(0.7)=560\\ \\n=5,a_{5}=800(0.7)^{(5-1)}=800(0.4)^4=192.08[/tex]

Rounding to nearest tenth of centimeter, the ball bounces 192.1 cm high on the 5th bounce.

The polar form of z = -7 - 8i is:

z = 3√13 (cos 230.2° + i sin 230.2°)

Converting -7 - 8i to polar form:

The rectangular form of a complex number is given by z = a + bi, where a is the real part and b is the imaginary part. In this case, a = -7 and b = -8.

The polar form of a complex number is given by z = r(cos θ + i sin θ), where:

r is the modulus (or absolute value), which represents the distance of the complex number from the origin in the complex plane.

θ is the argument (or angle), which represents the direction of the complex number relative to the positive real axis.

1. Finding modulus (r):

r = √(a² + b²) = √((-7)² + (-8)²) = √(113) = √(13 * 9) = √13 * 3 (using factorization and perfect squares)

Therefore, r = 3√13.

2. Finding argument (θ):

θ = arctan(b/a) = arctan((-8)/(-7)) ≈ 50.2° (using the arctangent function on a calculator). However, this only gives one possible angle for the complex number.

Note: The arctangent function typically outputs values between -90° and 90°, which corresponds to Quadrant 1 or 4 in the complex plane. Since -7 - 8i lies in Quadrant 3, we need to add 180° to get the correct angle:

θ = 50.2° + 180° = 230.2°

Therefore, the polar form of z = -7 - 8i is:

z = 3√13 (cos 230.2° + i sin 230.2°)

[tex]remainder=2802[/tex]

Step-by-step explanation:

Remainder Theorem: When a polynomial [tex]f(x)[/tex] is divided by [tex](x-a)[/tex] the remainder will be [tex]f(a)[/tex]

[tex]Here \ \ f(x)=x^3+6x^2-20x+450[/tex]

[tex]It\ is\ divided\ by\ (x-12)[/tex]

[tex]Then\ remainder =f(12)\\\\remainder=(12)^3+6(12)^2-20\times12+450\\\\remainder=1728+6\times144-240+450\\\\remainder=1728+864-240+450\\\\remainder=3042-240\\\\remainder=2802[/tex]

Final answer:

To find the remainder of the polynomial f(x) = x³ + 6x² - 20x + 450 when divided by (x - 12), we evaluate f(12) using the Remainder Theorem, which yields a remainder of 2802.

Explanation:

To find the remainder when the function f(x) = x³ + 6x² - 20x + 450 is divided by (x - 12), we use the Remainder Theorem. This theorem states that the remainder of a polynomial f(x) divided by (x - a) is f(a). Therefore, to find the remainder of f(x) divided by (x - 12), we evaluate f(12).

Substitute x with 12 into the function:

f(12) = (12)³ + 6(12)² - 20(12) + 450

f(12) = 1728 + 864 - 240 + 450

f(12) = 2802

Thus, the remainder is 2802.
