How many outcomes are in the sample space

Answer:

4 Dollars and 30 cents

Step-by-step explanation:

15.95 x 6 = 95.7

100-95.7= 4.30

Final answer:

Erin bought six shirts at $15.95 each, totaling $95.70. After paying with a $100 bill, she would receive $4.30 in change.

Explanation:

The question asks us to calculate the total cost of six shirts and then determine the change from a $100 bill. Erin bought six shirts that cost $15.95 each. To find the total cost, we multiply the price of one shirt by the number of shirts:

$15.95 × 6 = $95.70.

Next, we calculate the change Erin would receive if she paid with a $100 bill:

$100 - $95.70 = $4.30.

Therefore, Erin would receive $4.30 in change.

Answer:

10/14, 15/21

Step-by-step explanation:

WE are given a ratio 5/7

To find equivalent ratios it is sufficient to multiply both numerator and denominator by the same number

Let us take 2,3 for example.

When we multiply both numerator and denominator by 2, value does not change.

Hence we get equivalent fraction.

So 10/14 is one such fraction.

Next is multiply by 3

15/21 is another fraction.

Answer:

Each student would get 4 inches of ribbon

Step-by-step explanation:

Mrs. Barkley has 75 inches of ribbon and is splitting it between 18 students so you would divide 75 by 18. When you divide you get 4.166666... etc. So the answer would be 4

Each of the 18 students in Mrs. Barkley's class will receive 50 inches of ribbon when 75 feet of ribbon are divided equally among them.

The student has asked how many inches of ribbon each student will get if Mrs. Barkley has 75 feet of ribbon and splits it equally among 18 students. To solve this problem, we first need to convert feet to inches because there are 12 inches in a foot. Then we divide the total inches of ribbon by the number of students.

Total length of ribbon for each student= 75/18

The total length of ribbon for each student≈4.1667

So, each student will receive approximately 4.1667 feet of ribbon.

To find out how many inches this is, we'll convert this value to inches. Since 1 foot is equal to 12 inches, we can multiply the total length of the ribbon for each student by 12:

The total length of ribbon for each student (in inches)=4.1667×12

The total length of ribbon for each student (in inches)≈49.9999

Therefore, each student will receive approximately 50 inches of ribbon.

Final answer:

The probability of drawing a black pen first and then a red pen with replacement from a box of 10 pens is 20%.

Explanation:

To calculate the probability of drawing a black pen and then a red pen with replacement in a box that contains 10 pens, we should calculate the probability of each event separately and then multiply them since the events are independent.

There are 5 red pens, 4 black pens, and 1 blue pen, making a total of 10 pens. The probability of drawing a black pen is the number of black pens divided by the total number of pens: P(black) = 4/10 or 0.4.

Since the pen is replaced, the total stays the same. Therefore, the probability of then drawing a red pen is the number of red pens divided by the total number of pens: P(red) = 5/10 or 0.5.

To find the combined probability of both events happening in sequence (drawing a black pen and then a red pen), we multiply the two probabilities together: P(black and red) = P(black) × P(red) = 0.4 × 0.5 = 0.2 or 20%.

We must find the difference between 3 1/12 and 2 1/3. So we can first subtract 3 from 2 and we earn 1 whole number. Next we must subtract  1/12 and 1/3. This is the same as 3/36-12/36, which is -9/36 or -1/4. Since we can't have -1/4 we must subtract 1/4 from 1 and earn 3/4 as our answer.

Answer:

It will take 10 hours.

Step-by-step explanation:

We know distance = rate * time

Sally's rate = 55

Jim's rate = 65

We want Jim to be 100 miles ahead of Sally

The time will always be the same.

d =Sally's distance

Sally

d = 55t

Jim

d+100 = 65 t

We know have 2 equations with 2 unknowns.  Substitute d= 55t into Jim's equations

55t + 100 = 65t

Subtract 55t from both sides.

55t-55t + 100 = 65t-55t

100 = 10t

divide each side by 10

100/10 = 10t/10

10 = t

Option: D is the correct answer.

  D.    The slope of is 3, and passes through O.

It is given that:

AB is dilated by a scale factor of 3 to form AB .

Also, the line AB pass through the origin.

So, if AB pass through (0,0) and some point (x,y) then the slope of line AB is:

[tex]Slope=\dfrac{y-0}{x-0}\\\\i.e.\\\\Slope=\dfrac{y}{x}=3[/tex]

( Since, it is given the slope of AB is 3 )

Now , if AB is dilated to A'B' by a scale factor of 3 then

(0,0) → (0,0)

and

(x,y) → (3x,3y)

i.e. (0,0) and (3x,3y) will lie on A'B'.

Hence, the slope of line A'B' is given by:

[tex]Slope=\dfrac{3y-0}{3x-0}\\\\i.e.\\\\Slope=\dfrac{3y}{3x}\\\\i.e.\\\\Slope=\dfrac{y}{x}=3[/tex]

Hence, both have the same slope.

Answer:

f(x) = -38

Step-by-step explanation:

well f(x) is the same thing as y so just write it as y so its easier to understand.

y = -2x -13

take the x value they give you which in this case is 5 and plug it in to the x in your equation.

y = -2(5) -13

now just use a calculator or something and find that

y = -25 - 13

and finally

y = -38

now just change y back to f(x) if needed

Answer:

Angle ABC is 22 degrees

Angle BAC is 68 degrees

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

Work Shown:

Because there are just 3 points, we can refer to "angle BAC" as "angle A" and "angle ABC" as "angle B". Focus on the middle letter of each three-letter sequence.

The three angles A, B, C add up to 180 degrees. This is true for any triangle.

A+B+C = 180

(6x+8) + (2x+2) + 90 = 180 ... substitution

6x+8 + 2x+2 + 90 = 180

8x+100 = 180

8x+100-100 = 180-100 ... subtract 100 from both sides

8x = 80

8x/8 = 80/8 ... divide both sides by 8

x = 10

If x = 10, then angle BAC is

angle BAC = 6x+8

angle BAC = 6*10+8

angle BAC = 60+8

angle BAC = 68

Use x = 10 to find angle ABC as well

angle ABC = 2x+2

angle ABC = 2*10+2

angle ABC = 20+2

angle ABC = 22

The three angles of this triangle are A = 68, B = 22, C = 90

As a check, the three angles must add to 180

A+B+C = 180

68+22+90 = 180

180 = 180

Answers are confirmed

Another thing to notice is that A+B = 90 meaning that A and B are complementary angles. A+B = 68+22 = 90.

Answer:

4x - 3y = 36

Step-by-step explanation:

2/3x - 1/2y = 6

Multiply each side by 6 to get rid of the fractions

6*  (2/3x - 1/2y) = 6*6

Distribute the 6

12/3 x - 6/2y = 36

4x -3y = 36

Answer:

A

Step-by-step explanation:

given sin x ≈ 0.2588, then

x = [tex]sin^{-1}[/tex](0.2588) ≈ 15°

using the cofunction identity

cos x = sin(90 - x)

the complement of 15° is 90° - 15° = 75°, hence

cos 75° = sin(90 - 75)° = sin15° ≈ 0.2588

Final answer:

James cuts each of the three lasagnas into five equal parts, resulting in a total of 15 pieces of lasagna.

Explanation:

When James cuts each square lasagna into pieces that are each 1/5 of the lasagna, he's effectively dividing each whole lasagna into five equal parts. Since he has three whole lasagnas, each cut into 1/5-sized pieces, the total number of pieces he would end up with can be found by multiplying the number of pieces per lasagna by the number of lasagnas.

To calculate this, you multiply 5 (the number of pieces from one lasagna) by 3 (the number of lasagnas):

Multiply the number of pieces per lasagna (5) by the number of lasagnas (3).

5 pieces/lasagna × 3 lasagnas = 15 pieces

Thus, James cuts the lasagna into 15 pieces in total.

The center of the circle described by the equation x^2 + (y+4)^2 = 64 is at the point (0,-4), and the radius is 8.

In the context of a circle, the general equation form is (x-a)^2 + (y-b)^2 = r^2, where (a,b) is the center of the circle and r is its radius. Looking at your given equation x^2 + (y+4)^2 = 64, it is in this general format.

Here, the value of a is 0 (as there is no number being subtracted from x) and b is -4 (the y coordinate has been shifted 4 units down). Therefore, the center of the circle is at point (0,-4).

For the radius, since r^2 = 64, the radius r will be the square root of 64 which is 8.

Reflection about the y axis, and then about the x- axis

Step-by-step explanation:

When reflecting an object about the y- axis, the x-coordinates are multiplied with -1.

When reflecting an object about the x-axis, the y-coordinates are multiplied with -.

When reflecting about both axes, both coordinates are multiplied by -1.

Now looking at the coordinates of the two triangles:

A(2, -4) → A'(-2, 4)

B(5, -5) → B'(-5, 1)

C(4, -5) → C'(-4, 5)

All of the coordinates are multiplied by -1.

To write the slope-intercept form of a linear equation, we use the formula y = mx + b, where m represents the slope and b represents the y-intercept.

Answer:

3750 feet

Step-by-step explanation:

Given that Paulo begins at Stop 1 and then walks to Stop 2, then Stop 3, and then Stop 4. Then he walks to Stop 1 again.

Where stops are given by coordinates:

Stop 1 at (−2,1)

Stop 2 at (−2, −7) ​​

Stop 3 at (5,−7)

Stop 4 at (5, 1)

The path between each stop is a straight line. One unit on the coordinate grid equals 125 feet.

Now we need to find about what is the total distance Paulo walked.

So first we graph those points so that we can easily count the length of each side. then add each side to get the total length

length of rectangular path = 8+7+8+7=30

since one unit on the coordinate grid equals 125 feet. So to find the actual length we need to multiply 30 by 125 feet.

Hence final answer will be 125*30 = 3750 feet.
