Step-by-step explanation:

First we have to find the total length she swims in 1 day

= 2(length of the swimming pool) x no. of lengths she swims in 1 day

=2x30x20

=120m she covers in 1 day

10km = 10,000m

no of days= total distance/ distance she covers in 1 day

=10000/120

=83.3 days

Answer:

X = 41°

Step-by-step explanation:

[tex] \angle1 + \angle2 + \angle3 = 180 \degree [/tex]

[tex]Here \\ \angle1 = 105 \degree \\ \angle2 = ? \\ \angle3 = x[/tex]

[tex] \angle4 = 146 \degree[/tex]

[tex]here \: \angle2 + \angle4 = 180 \degree \\ \: (liner \: pair \: angle) degree\\ \angle2 + 146\degree = 180 \degree \\ \angle2 = 180 \degree - 146\degree \\ \angle2 = 34\degree[/tex]

[tex] \angle1 + \angle2 + \angle3 = 180 \degree \\ 105\degree + 34\degree + x = 180\degree \\ 139\degree + x = 180\degree \\ x = 180\degree - 149\degree \\ x = 41\degree[/tex]

Answer:

9-pack of hot dogs for $3.61

Answer:

Step-by-step explanation:

This is a question on the unit price. The better buy is the lower unit price. But that only works if you have 8 people to share the dogs with.

2 dogs cost 0.81

1 dog is 0.81/2 = 0.405 which you should write as 0.41

9 dogs are 3.61

1 dog is 3.61/9 = 0.401 what you (again) should be 0.41

Ever so marginally, you should pick the 2 dogs if there are only 2 people and 9 dogs if you are buying for a baseball team.

Answer:

Blue balloons = 12

Step-by-step explanation:

Total no of balloons = 21

Let us assume that the ratio of blue balloons to green balloons is 4:3.

Let there are 4x blue balloons and 3x green balloons.

ATQ,

4x+3x = 21

7x = 21

x = 3

Blue balloons = 4x

= 4(3)

= 12

Hence, she will have 12 blue balloons at her party.

Step-by-step explanation:

Answer:

Slope = 2, y-intercept = 3

Step-by-step explanation:

I will be calculating the slope of the line using these two points: (-1, 1) and (0, 3)

Slope = [tex]\frac{rise}{run}[/tex]

          = [tex]\frac{3-1}{0-(-1)}[/tex]

          = [tex]\frac{3-1}{0+1}[/tex]

          = 2

Based on the graph, the y-intercept is 3.

Answer:

12a)  4L - 6 = Perimeter

13) 4(6x + 9)

Step-by-step explanation:

for #12:  two sides of the rectangle are referred to as L

The other two sides can be referred to as L-3 (these sides are the width, which are 3 less than the length)

Perimeter = sum of all sides; so, 2L + 2(L-3)

P = 2L + 2L - 6

  = 4L - 6

Answer: 12. The expression is 2L+2(L-3)

13. The answer is 6x+9

Step-by-step explanation:

12. The perimeter of a rectangle is 2*length +2*width. So, in this case (when L is the length of the rectangle) the perimeter should be 2L+2(L-3). If you simplify you will get 4L-6.

13. The perimeter is just the value you get when all the sides of a shape are added. A square has 4 equal sides. So, just divide the perimeter, which in this case is (24x+36), by 4. You should get 6x+9.

[tex]40m^{3}[/tex]

Step-by-step explanation:

Because of order of operations, you do exponent first. [tex](2m)^{3} =8m^{3}[/tex]. Lastly 8 multiplied by 5 is 40, so the answer is [tex]40m^{3}[/tex]

Answer:

Answer:

n(A) = 6

Step-by-step explanation:

Let consider a set A = {a, m, b, d, h}. There are five elements in the set. The no of elements in a set is known its cardinality. Since set A has five elements, its cardinality number is 5. The cardinality of the set A is denoted by n(A).

Hence, from the given information:

The set A = {1, 2, 3, 4, 0, 7} have a cardinality number of 6

n(A) = 6

Approximate solutions are the estimate values of an equation

The approximate solution of the equation is x = 0.45

The equation is given as:

[tex]x^3 + 2x- 1= 0[/tex]

The iteration is given as:

[tex]x_{n+1} = \frac{1}{x_n^2 + 2}[/tex]

To start with, we have:

[tex]x_1 = 1[/tex]

So, we have:

[tex]x_2 = \frac{1}{1^2 + 2} = \frac 13 =0.33333333[/tex]

The next iteration is:

[tex]x_3 = \frac{1}{0.33333333^2 + 2} = 0.47368421102[/tex]

The next iteration is:

[tex]x_4 = \frac{1}{0.47368421102^2 + 2} = 0.4495641344[/tex]

The next iteration is:

[tex]x_5 = \frac{1}{0.4495641344^2 + 2} = 0.45411035264[/tex]

The next iteration is:

[tex]x_6 = \frac{1}{0.45411035264^2 + 2} = 0.45326473189[/tex]

Notice that:

x5 and x6 have the same value to 2 decimal places.

i.e. [tex]x_5 \approx x_6 = 0.45[/tex]

Hence, the approximate solution of the equation is x = 0.45

Answer:

The correct answer is:

Matthew's rate is higher by $50 per month.

Step-by-step explanation:

We know that Christopher's rate is $550 per month.

To find Matthew's rate, we will treat the data we have as ordered pairs:

(3, 1800)

(6, 3600)

(9, 5400)

We find the slope of the line between these points.  The formula for slope is:

Using the first two points, we have:

To verify Matthew saves the same amount each month, we will find the slope between the second two points and make sure they're the same:

Matthew's rate is $600 per month.

This is higher than Christopher's by 600-550=$50 per month.

Answer:

c

Step-by-step explanation:

I took the test and got it right

The correct equation that justifies why seven to the one-third power equals the cube root of seven is option C: [tex](7^{(1/3)})^3[/tex]=[tex]7^{(1/3 * 3)[/tex]=7.

C. Seven to the one-third power all raised to the third power equals seven to the one-third times three power equals seven.

Let's break down the steps:

Seven to the one-third power all raised to the third power:

[tex](7^{(1/3)})^3[/tex]

Using the property of exponents [tex](a^{(m*n)} = (a^m)^n)[/tex] to simplify:

[tex]7^{(1/3 * 3)[/tex]

The exponent 1/3 multiplied by 3 is equal to 1:

[tex]7^1[/tex]

Any number raised to the power of 1 is itself, so:

7

This justifies that [tex]7^{(1/3)[/tex] raised to the power of 3 is equal to 7.

Therefore, [tex]7^{(1/3)[/tex] is equal to the cube root of 7.
