Step-by-step explanation: The bus was late 15 out of 20 times. Therefore, the experimental probability that the bus will be late is 0.75.

Answer: {(5,0), (3,4)}

Step-by-step explanation:

You can apply the Substitution method:

- Solve for y from the second equation.

- Substitute into the first equation and solve for x.

Then:

[tex]y=10-2x[/tex]

[tex]x^2+y^2=25\\x^2+(10-2x)^2=25\\[/tex]

(Remember that: [tex](a\±b)^2=a^2\±2ab+b^2[/tex])

[tex]x^2+(10^2-2(10)(2x)+(2x)^2)=25\\x^2+100-40x+4x^2=25\\5x^2-40x+75=0\\x^2-8x+15=0\\(x-5)(x-3)=0\\\\x=5\\x=3[/tex]

Substitute the values obtained into one of the original equation and solve for y:

[tex]2(5)+y=10\\10+y=10\\y=0\\\\2(3)+y=10\\6+y=10\\y=4[/tex]

The solution set is: {(5,0), (3,4)}

Answer: 0, I think?

Step-by-step explanation: In order to do this equation, we want to get the variable on one side. In order to do this, we add 7 to both sides to cancel out the -7's. Now, we divide 9 on both sides, giving us 0.

Answer:

[tex](f\circ g)(3)=-7[/tex]

Step-by-step explanation:

The given functions are;

[tex]f(x)=-2x+7[/tex]

and

[tex]g(x)=x^2-2[/tex]

We need to first of all find [tex](f\circ g)(x)[/tex]

[tex](f\circ g)(x)=f(g(x))[/tex]

[tex](f\circ g)(x)=f(x^2-2)[/tex]

[tex](f\circ g)(x)=-2(x^2-2)+7[/tex]

[tex](f\circ g)(x)=-2x^2+4+7[/tex]

[tex](f\circ g)(x)=-2x^2+11[/tex]

We now plug in x=3

[tex](f\circ g)(3)=-2(3)^2+11[/tex]

[tex](f\circ g)(3)=-18+11[/tex]

[tex](f\circ g)(3)=-7[/tex]

Answer:

A. 8 cm sq

Step-by-step explanation:

Find the scale factor

new width/original width

8/1.6=5

calculate length of original rectangle

new length/scale factor

25/5=5cm

Find area of original rectangle

A=l×w

A=1.6×5=8cm²

A is the answer

You find the scale factor by doing 8÷1.6 which = 5

Then you do 25÷5=5

And then times 5 and 1.6 together to get 8cm sq

Answer:

Step-by-step explanation:

Compounded interest formula is

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Where [tex]A[/tex] is the final amount, [tex]P[/tex] is the principal, [tex]r[/tex] is the anual interest in decimal, [tex]n[/tex] is the numer of compounded periods in one year and [tex]t[/tex] is the time in years.

[tex]P=\$800\\r=0.09\\n=1\\t=4[/tex]

Notice that [tex]n=1[/tex], because the interest is compounded anually, if the interest is compounded, then [tex]n=12[/tex], because there would be 12 compound periods in one year.

Then, we replace all these vaules in the formula

[tex]A=P(1+\frac{r}{n})^{nt}\\A=800(1+\frac{0.09}{1})^{1(4)}=800(1.09)^{4}\\ A=1,129.26[/tex]

Therefore, after 4 years, the amount would be $1,129.27.

Answer:

Step-by-step explanation:

Seven

I imagine that 7 is the one giving you the problem. There are 29 steps between where A is and where B is. The problem is in the directions. If you follow the first direction, there are 29 squares separating them meaning that B and starts on square 31 and A starts on one. If, however, you read on, your find out that B actually starts on 29. Which is it? If you follow the first direction, you get the both land on 13. Here's how.

A's motion is 3 up 1 back. His net motion is that  he moves 2 forward.

B's motion is 5 down and 2 up. His not motion is - 3 each time

A                          B

1                            31

3                            28

5                            25

7                             22

9                             19

11                             16

13                             13

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

Let's do it again starting with the second direction

A                              B

1                               29

3                              26

5                               23

7                                20

9                                17

11                                14

13                                11 and they miss  but keep going. You might have to go another round

15                                 8

17                                  5

19                                  2 Now if you try going forward you can't so B uses As  rule.

21                                  4

23                                  6

25                                  8  And these two will never meet on this round.

I think you should follow the first rule.

27                                   10

28                                   12

25                                   14

22                                    16

19                                      18 another miss.    

Well you can carry it on. I would ask your teacher about this one.

I can give you an answer, but I don't know how you would find it on your own. The smallest number I found was 301

You can see that 2 and 5 do leave a remainder of 1.

You can also see the 301 / 3 leaves a remainder of 1

What about 4? 301 / 4 = 75 with a remainder of 1.

301 / 6 = 50 with a remainder of 1.

301/7 = 43 with no remainder.

What a strange question.

All of these from 2 to 6 divide into 300 evenly. 301 gives a remainder of 1.

But 301 = 7 * 43

Let the smaller to the 2 angles = x

Therefore the larger one is 3x + 2

The third angle = 90 degrees.

3x + 2 + x + 90 = 180                    Combine like terms on the left.

4x + 92 = 180                                Subtract 92 from both sides.

4x = 180 - 92

4x = 88                                          Divide by 4

x = 88/4

x = 22

So the three angles are

22

66 + 2 = 68

90

This problem seems much easier than the other 2.

Answer:

cscФ = 13/12

Step-by-step explanation:

∵ The terminal side of the angle Ф passes through point (5/13 , 12/13)

∵ x = 5/13 and y = 12/13

∵ x = cosФ and y = sinФ

∴ cosФ = 5/13

∴ sinФ = 12/13

∵ cscФ = 1/sinФ

∴ cscФ = 1 ÷ 12/13 = 13/12

Step-by-step explanation:

The volume (V) of the triangular prism is

V = area of triangular end × length

area of triangle = [tex]\frac{1}{2}[/tex] × 3.4 × 2.5 = 4.25 in², hence

V = 4.25 × 4.8 = 20.4 in³ → b

Answer: B

Step-by-step explanation:

The volume of a triangular prism can be achieved by the equation:

[tex]V=\frac{1}{2} *l*w*h[/tex]

similar to finding the volume of a regular right triangle, where you have:

[tex]a=\frac{1}{2} b*h[/tex]

Here all you are adding is the dimension of depth by multiplying that depth (l) by the equation for the area.

Answer:

¹²/₇

Step-by-step explanation:

Model ⁴/₇ × 3

Assume that you have three pies, each dived into seven slices.

There are only four slices remaining in each pie, that is, there is ⁴/₇ pie in each pie plate

The picture represents ⁴/₇ × 3.  

Model the product

Now, transfer slices to get as many filled pie plates as possible.

Count the total slices.

You have 12 slices, and each slice represents ⅐ of a pie.

You have ¹²/₇  pie.

∴ ⁴/₇ × 3 = ¹²/₇

Final answer:

A parallelogram is a quadrilateral with parallel and equal sides, but it does not necessarily have any right angles. The greatest number of right angles a parallelogram can have is two, which occurs when the parallelogram is a rectangle.

Explanation:

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length. In a parallelogram, the opposite angles are also equal. However, a parallelogram is not required to have any right angles, and in fact, most parallelograms do not have any right angles.

The greatest number of right angles a parallelogram can have is two. This would occur when the parallelogram is a rectangle, which is a special type of parallelogram. A rectangle has opposite sides that are parallel and equal in length, and all four angles are right angles, measuring 90 degrees each.

Therefore, the answer to Sarah's question is that the greatest number of right angles her parallelogram can have is two.

Final answer:

By applying the Pythagorean theorem, we find that the sum of the squares of the two shorter sides of triangle STV (7 and 11) is not equal to the square of the longest side (14). Therefore, triangle STV is not a right triangle.

Explanation:

To determine if triangle STV with sides of 7, 11, and 14 is a right triangle, we can apply the Pythagorean theorem, a² + b² = c², where c is the hypotenuse (the longest side of the triangle) and a and b are the other two sides. For triangle STV, assume that the side with a length of 14 units is the hypotenuse, and the sides with lengths of 7 and 11 units are the other two sides.

Now, let's calculate:

a² = 7² = 49

b² = 11² = 121

a² + b² = 49 + 121 = 170

c² = 14² = 196

Since 170 does not equal 196, the sums of the squares of the sides do not equal the square of the hypotenuse. Therefore, triangle STV is not a right triangle.

Step-by-step explanation:

given

[tex]\frac{x8x^2-8}{4x+4}[/tex] , x ≠ - 1

The x ≠ - 1 means that x cannot take the value of - 1 as this would make the denominator equal to zero which would make the fraction undefined.

Factor the numerator/ denominator

8x² - 8 = 8(x² - 1) ← factor out 8 from both terms

x² - 1 ← is a difference of squares, hence

8x² - 8 = 8(x - 1)(x + 1)

4x + 4 = 4(x + 1) ← factor out 4 from both terms

Thus the fraction now simplifies to

[tex]\frac{8(x-1)(x+1)}{4(x+1)}[/tex]

Cancel the 8 and 4 by 4 and cancel the factor (x + 1), leaving

=  2(x - 1) = 2x - 2 ← in the form ax + b
