Answer:

x = 12

Step-by-step explanation:

Pythagoras' Theorem

[tex]a^{2} = b^{2} + c^{2}[/tex]

a = 13

b = 5

c = x

[tex]13^{2} = 5^{2} + x^{2}\\169 = 25 + x^{2}\\169 - 25 = x^{2}\\144 = x^{2}\\12 = x[/tex]

After applying the Pythagorean theorem on the given right-angled triangle the value of x we get 12.

A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.

The Pythagoras theorem for a right-angled triangle:

(Hypotenuse)²= (Perpendicular)² + (Base)²

For the given triangle:

The hypotenuse 'MC' = 13

The perpendicular 'MN' = 5

Base 'NC' = x

Substituting these values into the Pythagorean theorem:

(13)²= (5)² + (x)²

Simplifying the square,

169 = 25 + x²

Subtracting 25 we get,

x² = 144

Take square root on both sides,

x = 12

Hence,

The value of x is 12.

To calculate the sale price of the sweatshirt, multiply the original price by the discount rate to get the discount amount and subtract from the original price. The sweatshirt is now priced at $24.

We can find the amount discounted by multiplying the original price of the sweatshirt by the discount rate. So, we calculate 60% of $60. First distinguish that 60% is the same as 0.60 in decimal form. Therefore, we multiply $60 by 0.60 (60%) to get $36. This is the amount that is discounted from the original price. To find the new price after discount, subtract this amount from the original price. So, $60 - $36 equals $24. Therefore, the sweatshirt on sale is now priced at $24.

Answer:

y=8x-69

Step-by-step explanation:

you would use the equation y-y1 = m (x - x1)

plug in m = 8 , y1 = 3, x1 = 9

now you have y - 3 = 8 (x-9)

distribute 8 --> y-3 = 8x - 72

add three to both sides to get y = 8x - 69

Answer:

[tex]y-3=8(x-9)[/tex]

Step-by-step explanation:

We are given that a line has a slope (m) of 8 and passes through the point (9,3).

We want to write the equation of this line.

There are three ways to write the equation of the line:

As the problem doesn't specify that we have to write the equation in a specific format, any one of the three work.

However, let's write it in point-slope form, as it is the easiest one to write in this case.  

As we are already given the point and the slope, we can plug them into the equation.

Starting with the slope, substitute 8 as m in the equation.

[tex]y-y_1=8(x-x_1)[/tex]

Now, substitute 9 as [tex]x_1[/tex] and 3 as [tex]y_1[/tex].

We get:

[tex]y-3=8(x-9)[/tex]

Answer:

The Total earning of Paula riddle from 6 pm to 11 pm is $7.25  

Step-by-step explanation:

Given as :

Paula riddle charges per hour before 9 pm = $2.25 per hour

Paula riddle charges per hour after 9 pm = $2.75  per hour

Let The Total earning of Paula riddle from 6 pm to 11 pm = $A

Now, According to question

∵ before 9 pm , charges = $2.25 per hour

The time spend between 6 pm to 9 pm = 3 hours

So, The charge between 6 pm to 9 pm = $2.25 per hours × 3 hours

i.e  The charge between 6 pm to 9 pm = $6.75

Again

After 9 pm , charges = $2.75 per hour

The time spend between 9 pm to 11 pm = 2 hours

So, The charge between 9 pm to 11 pm = $2.75 per hours × 2 hours

i.e  The charge between 9 pm to 11 pm = $5.5

So, The Total earning of Paula riddle from 6 pm to 11 pm =  charge between 6 pm to 9 pm + charge between 9 pm to 11 pm

i.e A = $6.75 + $5.5

Or, A = $7.25

So, The Total earning of Paula riddle from 6 pm to 11 pm = A = $7.25

Hence, The Total earning of Paula riddle from 6 pm to 11 pm is $7.25  Answer

The given system is

2x-y=4

x-y=-2

We write the system in slope-intercept form:

y=2x-4

y=x+2

The first equation has slope of 2 and y-intercept at (0,-4)

When y=0, x=2.

We plot (0,-4) and (2,0) to graph this first equation.

The second equation has a slope of 1 and a y-intercept at (0,2)

Also when y=0, x=-2.

We plot (0,2) and (-2,0) and draw a straight line through them.

Step-by-step explanation:

to work out surface area you need to figure out the area of each face on the shape.

the first side is 7.5 x 9 = 67.5

there are two of these sides

this makes 135mm

the top side is (4.5 x 6) / 2

this makes 13.5

there are also two of these sides making 27mm

finally the back side is 4.5 x 9 = 40.5

there are only one of these sides

this makes 40.5mm

finally you need to add all these sides

135 + 27 + 40.5 = 202.5

the surface area is 202.5mm

Final answer:

Laura earns $18 per hour, and for 8 hours of work, she would make $144.

Explanation:

The question asks us to determine how much Laura would make for 8 hours of work, given that she made $324 for 18 hours of work. To find the hourly rate, we divide the total amount earned by the total hours worked. Then we multiply the hourly rate by the number of hours we want to find the earnings for.

To calculate Laura's hourly rate: $324 / 18 hours = $18 per hour.

Now, we can find out Laura's earnings for 8 hours: $18 per hour * 8 hours = $144.

Therefore, Laura would make $144 for 8 hours of work at the same rate.

Answer:

30 minutes

Step-by-step explanation:

Let

y ---> the distance in miles    

x ---> the time in minutes

Remember that

[tex]1\ h=60\ min[/tex]

[tex]766\frac{2}{3}\ mi=\frac{766*3+2}{3}=\frac{2,300}{3}\ mi[/tex]

we have the ordered pairs

[tex](20,\frac{2,300}{3}),(60,2,300)[/tex]

Find the slope

[tex]m=(2,300-\frac{2,300}{3})/(60-20)[/tex]

[tex]m=(\frac{4,600}{3})/(40)[/tex]

[tex]m=\frac{4,600}{120}\\\\m=\frac{115}{3}\ mi/min[/tex]  

Find the linear equation in point slope form

[tex]y-y1=m(x-x1)[/tex]

we have

[tex]m=\frac{115}{3}[/tex]

[tex]point\ (60,2,300)[/tex]

substitute

[tex]y-2,300=\frac{115}{3}(x-60)[/tex]

[tex]y-2,300=\frac{115}{3}x-2,300\\\\y=\frac{115}{3}x[/tex]

Is a proportional relationship between the variables x and y (speed)

For y=1,150 miles

substitute the value of y in the linear equation and solve for x

[tex]1,150=\frac{115}{3}x\\\\x=1,150(3)/115\\\\x=30\ minutes[/tex]

Final answer:

It takes approximately 30 minutes for the shadow to travel 1,150 miles during a solar eclipse.

Explanation:

To determine the time it takes for the shadow to travel 1,150 miles, we can set up a proportion using the given information. Let's call the time it takes to travel 1,150 miles 't'. We can set up the proportion:

766.67 miles / 20 minutes = 1,150 miles / t

Now, let's solve for 't'. We can cross-multiply:

766.67 * t = 20 * 1,150

Divide both sides by 766.67:

t = (20 * 1,150) / 766.67

Simplifying the right side of the equation gives us:

t ≈ 30

Therefore, it takes approximately 30 minutes for the shadow to travel 1,150 miles.

Step-by-step explanation:

The probability that a randomly selected dog is female, given it is a Chihuahua, is 3/11. This is calculated by dividing the number of female Chihuahuas (3) by the total number of Chihuahuas (11) in the store.

Probability of Selecting a Female Chihuahua

First, let's determine the total number of Chihuahuas in the store. Since the store has 25 dogs and 14 of them are not Chihuahuas, we subtract 14 from 25 to get the number of Chihuahuas:

25 - 14 = 11

There are 11 Chihuahuas in the store. We are given that there are 3 female Chihuahuas. Therefore, the probability that a randomly selected dog is a female Chihuahua is the number of female Chihuahuas divided by the total number of Chihuahuas:

Probability = Number of Female Chihuahuas / Total Number of Chihuahuas = 3 / 11

This calculation gives us the probability of 3/11 that a dog selected at random is female, given it is a Chihuahua.
