15. A movie is
1 7/8
hours long. After 45 minutes, how much of the movie is left?

Start at 3, subtract 5 and you get -2

Could you retake the photo

Answer:

1/24 chance

Step-by-step explanation:

To begin you would need to find the probability of picking a green sock which would be 3/9; and you could simplify this to 1/3.

After that you need to find the probability of picking a purple sock out of the 8 left, which would provide you with 1/8. To find the probability of both you would multiply 1/8 by 1/3 to find the combined probability which would leave you with 1/24.

The value of the home after the tenth year is 67500.

To find the value of the home after the tenth year?

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Given that:

Principal=P=$225000

Rate of interest=R=3%

Time=10 year

By the use of formula:

[tex]I=\frac{PRT}{100}[/tex]

[tex]I=\frac{225000*3*10}{100} \\\\I=22500*3\\\\I=67500[/tex]

So, the value of the home after the tenth year is 67500.

Hi! I'm happy to help!

To solve this problem, we have to find the slope, which is rise over run, or how much the line rises and how far forward the line goes.

We find the slope using this formula (slope formula)

m(slope)=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]

This refers to the second y point minus the first y point, divided by the second x point minus the first x point. Y refers to the y axis, so that is the rise, because it is the difference of height in the line. X refers to the x axis, so that is the run, because it is the difference in how far it travels forward.

Our second y point is -2, our first y point is also -2. Our second x point is -2, and our first y point is 4. Let's plug in our values.

[tex]\frac{-2-(-2)}{-2-4}[/tex]

Let's simplify this so there isn't a double negative.

[tex]\frac{-2+2}{-2-4}[/tex]

Now, let's solve

[tex]\frac{0}{-6}[/tex]

0 divided by -6, is still 0, so there is no slope or the slope is 0. This means that the line is horizontal and the y coordinate doesn't change.

Answer:

There are 240 boys.

Step-by-step explanation:

There are five boys to every three girls in an introductory Chinese course. Given that there are 384 students enrolled in total, we want to determine the amount of students which are boys.

Let b represent the number of boys and g girls.

Since the ratio is 5:3, we can write that:

[tex]\displaystyle \frac{5}{3} = \frac{b}{g}[/tex]

And since the total number of students is 384:

[tex]b + g = 384[/tex]

From the first equation, cross-multiply:

[tex]5g = 3b[/tex]

Solve for g:

[tex]\displaystyle g = \frac{3}{5} b[/tex]

Substitute:

[tex]\displaystyle b + \left (\frac{3}{5} b\right) = 384[/tex]

Simplify:

[tex]\displaystyle \frac{8}{5} b = 384[/tex]

Solve for b:

[tex]\displaystyle b = \frac{5}{8}\left(384\right) = 240[/tex]

In conclusion, 240 of the total students are boys.

The argument; if he did not get a good wage, then he must not have studied medicine is valid.

Let P represent "He studies medicine"

Let Q represent "He gets a good job"

Let R represent "He gets a good wage"

The argument can be written as:

P → Q

Q → R

¬R

∴ ¬P (conclusion: he did not study medicine)

Assume for contradiction that the argument is invalid:

P → Q

Q → R

¬R

P (assumption for contradiction: he studied medicine)

Use modus ponens to derive Q from (5) and (1):

Q (from 1 and 5 using MP)

Use modus ponens again to derive R from (6) and (2):

R (from 2 and 6 using MP)

This contradicts ¬R in (3), so our assumption in (5) must be false. Therefore, we can conclude that the argument is valid:

The square root of 1296 would equal 36, so, 36 - 36 = 0.

2x-8x=-5-3

6x=-2

6x/6=-2/6

x=-3

part 2

I can't so please help me

Answer:

Step-by-step explanation:

One

2x + 3 = 8x - 5                Add 5 to both sides

2x + 3 + 5 = 8x               Combine

2x + 8 = 8x                      Subtract 2x from both sides.

8 = 8x - 2x                       Combine

8 = 6x                              Divide by 6

x = 8/6

x = 8.333

Two

3x + 2 = 4                       Subtract 2 from both sides

3x = 4 - 2

3x = 2                             Divide by 3

x = 2/3

2y + 6 = 5                     Subtract 6 from both sides

2y = 5 - 6

2y = -1                          Divide by 2

y = - 1/2

x + y = 2/3 - 1/2

x + y = 4/6 - 3/6

x + y = 1/6

We are required to find how much the polygon has rotated after 12 minutes

The number of times the polygon has rotated after 12 minutes is 72°

Number of sides of the polygon = 60

The polygon rotates every minute, that is

1 rotation = 1 minutes

12 rotation = 12 minutes

one rotation of the clock is 360°

Number of times the polygon has rotated after 12 minutes = one rotation of the clock / Number of sides of the polygon × number of minutes

= 360°/60 × 12

= 6 × 12

= 72°

So, first, we have to establish how much the base rent ends up costing. So to find that, we do 1,800x12=21,600. So the base rent is $21,600. Then, we add the 4% of sales which is 125,000x0.04=5,000. So, we add $21,600 with $5,000 and we get a final answer of $26,600 owed at the end of the year :)

Answer:

51 cm²

Step-by-step explanation:

Let's ASSUME that the vertical measurements are taken perpendicular to the roughly horizontal baselines.

The three yellow triangles are all similar

the upper small triangle has height 3 and base 6 cm. The ratio of the lengths is 6/3 = 2

This means the medium (overlapping) triangle has lengths 10 - 3 = 7 and 7(2) = 14 cm

Area of the large triangle is ½(14 + 6)(10) = 100 cm²

Area of the overlapping yellow triangle is ½(7)(14) = 49 cm²

Exposed area of the blue triangle is 100 - 49 = 51 cm²

Both triangles have an area of 100 square centimeters and the area of the blue triangle showing is 51 square centimeters.

Based on the information given from statement, we can determine the missing length of the yellow triangle by means of simmilarity ratios, that is:

[tex]\frac{3\,cm}{6\,cm} = \frac{10\,cm}{x}[/tex] (1)

Where [tex]x[/tex] is the base of the yellow triangle, in centimeters.

Now we proceed to find the length base:

[tex]x = \frac{6\,cm}{3\,cm}\times 10\,cm[/tex]

[tex]x = 20\,cm[/tex]

The area of the triangle can be found by means of the following expression:

[tex]A = \frac{1}{2}\cdot b\cdot h[/tex] (2)

Where:

If we know that [tex]b = 20\,cm[/tex] and [tex]h = 10\,cm[/tex], then the area of the triangle is:

[tex]A = \frac{1}{2}\cdot (20\,cm)\cdot (10\,cm)[/tex]

[tex]A = 100\,cm^{2}[/tex]

The area of the yellow triangle is 100 square centimeters and the area of the blue triangle is also 100 square centimeters due to congruency. The dimensions of the section of the yellow triangle overlapping the blue triangle are [tex]b = 14\,cm[/tex] and [tex]h = 7\,cm[/tex]. The area of this section is:

[tex]A' = \frac{1}{2}\cdot (14\,cm)\cdot (7\,cm)[/tex]

[tex]A' = 49\,cm^{2}[/tex]

And the area of the rest of the blue triangle is:

[tex]A'' = A - A'[/tex] (2)

[tex]A'' = 100\,cm^{2}-49\,cm^{2}[/tex]

[tex]A'' = 51\,cm^{2}[/tex]

In a nutshell, both triangles have an area of 100 square centimeters and the area of the blue triangle showing is 51 square centimeters.

The word “sum” simply means “to add” or “addition” in mathematical terms

So, we have to ADD -12 from 8 from each other.

Positives are on the RIGHT side of the number line whereas negatives are on the LEFT side of the number line

Start at -12 and go UP 8 spaces to the right.

Answer:

B

Step-by-step explanation:

(7×2)⁶

when we put a number to the power of something, we need to include the whole number. bit just a part of it.

so, it must be 7⁶×2⁶

just think about the simple example 6², which we could write as (2×3)².

would it be sufficient to e.g. square only one of the factors ?

6² = 36

but e.g. 2×3² = 18. so, that's really not it.

or add the two factors and then square them ?

2+3 = 5. 5² = 25. so, that's not it either.

or multiply the exponent in ?

2×3×2 = 12. so that's not it either.

no, it truly is you need to do the operation to all parts.

2²×3² = 4×9 = 36. yes, that fits.

therefore, B is the right answer.
