The solution to the total distance covered by Luke is that; It is less than a kilometer

How do you calculate total distance?

We are given;

Distance from luke's house to skating rink = 0.4 km

Distance from Mark's house to skating rink = 0.25 km

Since luke is walking to mark's house after getting to the skating rink, then;

Total distance covered by luke = 0.4 km + 0.25 km = 0.65 km

In conclusion, total distance covered by luke is less than a kilometer.

Answer:

(a) 5 cm

(b) 156.5 cm

Step-by-step explanation:

1. In 5th grade, Ali was 136.5 cm, then in 6th, grade he was 141.5 cm. Now, in 7th grade, Ali is 146.5 cm. As you can see, Ali's height increases 5 cm per grade.

2. Since 9th grade is in two years, we add 10 cm to Ali's 7th grade height.

Answer:

W=9/10

Step-by-step explanation:

To find out what W equals to, we need to set the equation equal to W:

W- 2/5 = 1/2

Add 2/5 to both sides:

W = 1/2 + 2/5

W = 9/10 ( I added 5/10 + 4/10)

So W = 9/10 and Bingo was his namo!

Answer:

y=1/8x−3

Step-by-step explanation:

Answer:

a. y = 12400x + 26800

b. $113600

c. end of the 5th year

Step-by-step explanation:

a.

We are given 2 points, (1, 39200) and (4, 76400).

We are looking for the equation of the line that passes through those two points.

slope = (76400 - 39200)/(4 - 1) = 12400

y = mx + b

y = 12400x + b

We have when x = 1 y = 39200.

39200 = 12400(1) + b

b = 26800

The equation is

y = 12400x + 26800

b.

y = 12400x + 26800

x = 7

y = 12400(7) + 26800

y = 113600

c.

y = 12400x + 26800

88800 = 12400x + 26800

62000 = 12400x

x = 5

Answer:

$66.56

Step-by-step explanation:

8% = 0.08

52 * 0.08 = 4.16

20% = 0.20

52*0.20 = 10.4

$52 + $4.16 + $10.4 = $66.56

Part A

P(white) = (3 white)/(10 total) = 3/10

Answer: 3/10

==============================================

Part B

10 total, 3 are white

10-3 = 7 are not white so they are either black or red

P(black or red) = 7/10

Answer: 7/10

==============================================

Part C

Earlier in part B we calculated 7 beads that weren't white

This means P(not white) = P(black or red) = 7/10

They are the same probability just phrased slightly different ways.

Answer: 7/10

==============================================

Part D

There aren't any blue beads (unless there's a typo somewhere). So the probability of picking not blue is 100% or we represent this as the value 1.

The amount of paint is the volume of paint needed.

The amount of paint needed is 0.065312 cubic meters

How to determine the amount of paint needed

The volume of a hemisphere is:

[tex]V = \frac 23\pi r^3[/tex]

Differentiate the above equation

[tex]V' = 2\pi r^2 r'[/tex]

The above equation represents the estimate of the amount of paint needed.

Where:

r represents the radius (r = 52/2 m)r' represents the thickness (r' = 0.04 cm)

So, we have:

[tex]V' = 2\pi r^2 r'[/tex]

[tex]V' = 2 * 3.14 * (52/2\ m)^2 * (0.04cm)[/tex]

[tex]V' = 2 * 3.14 * (26\ m)^2 * (0.04cm)[/tex]

Express cm as m

[tex]V' = 2 * 3.14 * (26\ m)^2 * (0.0004m)[/tex]

[tex]V' = 0.065312 m^3[/tex]

Hence, the amount of paint needed is 0.065312 cubic meters

Answer:

12/12

This is because you multiply the denominator and the numerator by 2 you get 12/12

Answer:

Any fraction with the same number as the numerator and denominator.

Step-by-step explanation:

There should be options for this question, but the answer would be any fraction that has the same number as the numerator and as the denominator, like 1/1, 2/2, 3/3, etc. The fraction 6/6 is equal to 1, and so is every other fraction with identical numerators and denominators. Hope this helps :)

Using the general equation formula;
y-y1=m(x-x1)

y1=20 and x1=4
Since the two lines are perpendicular, they have the same gradients
But gradient for y=4x+5 is 4
Therefore m of the equation is 4

Substituting all this into the general formula;

y-20=4(x-4)
y-20=4x-16
y=4x-16+20
y=4x+4

First let's take our two given equations

-2x-9y=-25

-4x-9y=-23

Now we need to cancel out either x or y by making them the same values, but opposite on being negative or positive

We do this by multiplying the entire equation by a number

-1(-4x-9y=-23)=4x+9y=23

Now we have a new equation

-2x-9y=-25

4x+9y=23

Combine the two equations and your y will cancel out

2x=-2

Now we need to find x

2x=-2

Divide by 2 on each side

x=-1

Now we need to plugin our x to find the y by plugging the x into any of the first given equations

-2(-1)-9y=-25

2-9y=-25

-2 -2

-9y=-27

Divide by -9 on each side

y=3

x=-1, y=3

My aunt's age is 43.

My brother's age is 16.

My mother's age is 41.

What are the current ages?

In order to determine the current ages, the year the ages are been calculated has to be determined first. The year can be determined by adding my Tali's age to the year he was born.

2008 + 13 = 2021

What is my aunt's age = 2021 - 1978 = 43

What is my brother's age = 2021 - 2005 = 16

What is my mother's age = 2021 - 1980 = 41

To get the expected value, multiply each value of x by the corresponding probability P(x), then take the total:

E[X] = ∑ x P(x)

E[X] = 0 •0.55 + 1 •0.20 + 2 •0.25

E[X] = 0 + 0.20 + 0.50

E[X] = 0.70

To get the standard deviation, compute the variance, defined by

Var[X] = E[(X - E[X])²] = E[X²] - E[X]²

Compute the second moment:

E[X²] = ∑ x² P(x)

E[X²] = 0² •0.55 + 1² •0.20 + 2² •0.25

E[X²] = 0 + 0.20 + 1

E[X²] = 1.2

Then the variance is

Var[X] = 1.2 - 0.70²

Var[X] = 0.71

and the standard deviation is the square root of this,

√(Var[X]) ≈ 0.8426
