Answer:

12.7

Step-by-step explanation:

Its a pythagerous question question

so if the ladder is 8 feet from the wall the base is 8

and the ladder is 15 foot and is the hypotemuse

so 15^2-8^2=161^2

The root of 161 = 12.69 rounded to 2 dp

so 12.7

The distance far the top of the ladder from the ground is 12.7 feet

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

We are given that;

Length= 15foot

Base= 8feet

Now,

In this case, the ladder is the hypotenuse, and the base and the height are the legs. So, we can write:

15^2 = 8^2 + h^2

where h is the height of the ladder from the ground. Solving for h, we get:

h^2 = 15^2 - 8^2

h^2 = 225 - 64

h^2 = 161

h = sqrt(161)

h = 12.688

Therefore, by  Pythagoras theorem the answer will be 12.7 feet.

An associate in a scatter plot tells us the relation between the two variables. The points that are true about the given scatter plot are C and F.

An associate in a scatter plot tells us the relation between the two variables. There are 4 types of associates:

Positive associate: If the value of one variable is increasing the value of another increase as well, but the relation is not linear.

Negative associate: If the value of one variable is decreasing with the value of another increasing as well, but the relation is not linear.

Linear Associate: If the value of one is dependent on the other such that they follow a function of line, and all the data points are on that function line.

Non-linear Associate: If the data points of the plot are scattered and random, such that there is no relationship between the points.

Answer:

the book store selling 7 books for $39.55 (the book store)

Step-by-step explanation:

we have to calculate what each book costs. to find out what each book costs, we have to use division...

so for the book store:

39.55 / 7 = 5.65       -       this means that each book costs $5.65 by itself

for the online store:

24.96 / 3 = 8.32       -       this means that each book costs $8.32 by itself

now we have to compare the prices... $5.65 costs less than $8.32, so the book store would have a lower unit price.

Answer:

$450

Step-by-step explanation:

Let E be the amount of money Ethan starts with, J be the amount Jun Wei starts with, and R be the amount Raj starts with. Let M be the total amount of money to start with.

To start:

[tex]E:J:R = 5:6:9[/tex]

This means Ethan has 5/20 of M, the money to start with. This reduces to 1/4 of M.

Afterwards:

[tex](E-50):J:R = 3:4:6[/tex]

This means Ethan has 3/13 of the remaining money (which is M-50!) after giving up 50. So

E = (M/4), or 4E = M

and

[tex](E - 50) = 3/13 * (M - 50)[/tex]

We know 4E = M, so we can substitute that in:

[tex](E - 50) = 3/13 * (4E - 50)E - 50 = (12/13)E - 150/13E - 650/13 = (12/13)E - 150/13(1/13)E = 500/13E = 500[/tex]

That's how much money Ethan had to start with. But we're asked how much he has AFTER giving $50 away, so that's $450.

Answer:

159.25cm²

Step-by-step explanation:

A=lw

A=12×10cm

The rectangle’s area is 120cm² 

First, substitute the given information into the equation for the area of a circle.

A=πr²

A=(3.14)(5²)

A=3.14×25

A=78.5

Next, because the figure is only half of a circle, divide this in two.

78.5/2= 39.25cm²

Asc=39.25cm²

Add the two areas together.

A=Ar+Asc

120cm²+39.25cm²

Step-by-step explanation:

A solid line passes through (-1, 0) and (0, 3). The area to the left of the line is shaded gray.

Here we have the inequality:

3y - 9x ≥ 9

First, we should isolate y on one side of the inequality.

3y  ≥ 9x + 9

y  ≥ 3x + 3

Then, the graph will be a solid line of the form:

y =  3x + 3

Where the line is solid because the points on the line are solutions, and we need to shade all the region above the line.

Also, notice that for the line:

y = 3x + 3

if x = -1 we have:

y = 3*(-1) + 3 = 0

if x = 0 we have:

y = 3*0 + 3 = 3

Then the line passes through (0, 3) and (-1, 0). So the correct option is the second one.

Volume = l·w·h

After cutouts:

l = 14 - 2x

w = 6 - 2x

h = x

V = (14 - 2x)(6 - 2x)(x) in3

V = 4x3 - 40x2 + 84x in3

To maximize the volume, take the derivative of V with respect to x, set it equal to zero, and solve for x:

dV/dx = 0 = 12x2 - 80x + 24

x2 - (20/3)x + 7 = 0

x = (10 ± √37)/3 in

Since (6 - 2x) yields a negative number for x = (10 + √37)/3 we use only x = (10 - √37)/3

Thus, the dimensions are:

l = 14 - 2x = 11.39 in

w = 6 - 2x = 3.39 in

h = x = 1.31 in

Answer:

Step-by-step explanation:

The evaluated expression of 3x² + 4y⁰(x - 1) when x = 4 and y = 5 is  60.

What is Substitution?

Substitution simply means to put in place another. Therefore, let's substitute the value of x and y in the mathematical expression.

3x² + 4y⁰(x - 1)

Therefore,

y⁰ = 1

3x² + 4y⁰(x - 1)

3x² + 4y⁰(x - 1)

3x² + 4(x - 1)

3x² + 4x - 4

Therefore, when x = 4 and y = 5

3(4)² + 4(4) - 4

48 + 16 - 4 = 60
