Spin a spinner numbered 1-8 two times, land on two the first time and
land on a factor of 8 the second time

Answers

Answer 1
The correct probability is 1/16.

Explanation:

There is 1 section marked 8 out of 8 sections.  This makes the probability of landing on an 8 1/8.

The factors of 4 on this spinner are 1, 2, 4 and 8.  This makes 4 sections out of 8, which makes the probability of landing on a factor of 8 equal 4/8=1/2.

Together, the probability of both events would be 1/8(1/2) = 1/16.
Answer 2

Answer:

Required probability = 1/16

Step-by-step explanation:

When we spin a spinner numbered 1-8, we find that each spin is independent of the other.

HEnce probability for getting any number from 1 to 8 will be equal to 1/8 and remain the same for each spin.

So Probability on two for the first time and factor of 8 on the second time

=Prob (landing on 2)*Prob (landing on any factor of 8)

P(landing on 2) = 1/8

Factors of 8 are 1,2,4,8

Prob (landing on factor of 8) = 4/8

Hence required prob = 1/8(4/8) =1/16

Explain how you can determine that the following system has one unique solution – without actually solving the system. 2x+y=4 , 2y=6-2x

Answers

Answer:  The slopes are different

To compare the lines put them both in slope intercept form. The first equation will be y = -2x + 4 and the second equation will be y = -1x + 6. The slopes of the 2 graphs are different. These means that they are going in different directions. Therefore, they will cross a one unique point.

Answer:

Both equations has different slope , so the system of equation have one unique solution.

Step-by-step explanation:

[tex]2x+y=4[/tex] , [tex]2y=6-2x[/tex]

To determine that the system of equation has unique solution, we need to find out the slope.

To find slope, we write the equation in the form of y=mx+b

Where m  is the slope and b is the y intercept

[tex]2x+y=4[/tex]

Subtract 2x on both sides

[tex]y=-2x+4[/tex]

here, m= -2 is the slope

[tex]2y=6-2x[/tex]

Divide both sides by 2

[tex]y=3-x[/tex]

[tex]y=-x+3[/tex]

Slope m = -1

Both equations has different slope , so the system of equation have one unique solution.

Chris needs 3 1/2 cups of flour. His only clean measuring cup holds 1/3 cup. how many 1/3 cups of flour does Chris need?

Answers

He will need 10 1/2 (1/3) cups
Final answer:

To find the number of 1/3 cups of flour Chris needs, we need to divide the total amount of flour needed by the amount that can be measured with the 1/3 cup measuring cup. In this case, Chris needs 28 1/2 cups of flour.

Explanation:

To find the number of 1/3 cups of flour Chris needs, we need to divide the total amount of flour needed (3 1/2 cups) by the amount that can be measured with the 1/3 cup measuring cup.

To do this, we convert the whole number 3 to thirds by multiplying by 3, which gives us 9 thirds. Then we add the 1/2 cup, which is equivalent to 3/6 or 6/12. So, the total amount in thirds is 9 + 6/12 = 9 1/2 thirds.

Now, we divide the total number of thirds by the number of thirds in one 1/3 cup.

9 1/2 thirds ÷ 1/3 third/cup = (9 1/2) ÷ (1/3) = (19/2) ÷ (1/3) = 19/2 × 3/1 = 19/2 × 3/1 = 57/2 = 28 1/2 cups.

(2 1/2)/(5/8)

Now, if you remember, when dividing with fractions, you may multiply with the reciprocal of the fraction that’s dividing. What that means is, if you flip the bottom fraction from (5/8) to (8/5), you make your life easier by multiplying.

(2 1/2) • (8/5)

To make things even easier, let’s turn 2 1/2 into an improper fraction. This turns it into (5/2). So...

I need help on any of these y’all can help on. Plzzz. (points)

Answers

What you have here is the reflection problem. All you have to do is reflect from the original points over the x-axis or the y-axis.
1.) A(2,2), B(5,4), C(5,1) You have to reflect over the x-axis. And over the axis is (+,-), so the y-intercept must be negative. And the answer to that is simple: A'(2,-2), B'(5,-4), C'(5,-1). For reflection, all you have to do change the signs depends what quarter you on: Q1(+,+), Q2(-,+), Q3(-,-), Q4(+,-).
2.) A(-1,2), B(2,-1), C(5,2), D(2,5) Now this is the part you need to pay close attention on. As you can see figure A is already over y-axis, but that doesn't mean you can't reflect it. It means you got the new y-axis, which is: (-2,0). 
So the answer is this: A'(-3,2), B'(-4,-1), C'(-7,2), D'(-4,5).
3.) B(1,-2)=>B'(1,2) Remember what we discuss before, "...all you have to do is change the signs depends what quarter you on...." And that actually what this showing us, now you have figure it out whether it reflect over x-axis or the y-axis. You notice that only the y-intercept had change the signs, so it must be: x-axis. Because only Q4 is reflecting to Q1.
4.) J(-3,5)=>J'(-3,-5) Okay, J is the point for Q2 and J' is for Q3. The answer is it reflect over the x-axis.
5.) W(-7,-4)=>W'(7,-4) W in Q3 and W' in Q4. It reflect over the y-axis.
6.) Same as we did for question 2, we got the new y-axis (which is (-1,0)). The question is asking us what is the when we reflect X(4,2) over y-axis. And the answer is X'(-5,2).
7.) Same as the previous question, Y(4,4) over y-axis and the answer is: Y'(-6,4).
8.) Z(0,2) the answer is Z'(-2,2).
9.) For this question, it asking us to graph the whole triangle that is reflect it from the original triangle over the x-axis. The correct answer is: X'(4,-2), Y'(4,-4), Z'(0,-2).

A. 1/2

Answers

Okay so I am not 100% sure but I think it is C. 1/12;

Because if you rearrange all the letters so that W is is the beginning you get 6 different combinations.

Then I multiplied those 6 combinations by 4 because there are 4 letters.

Once I multiplied I got 2/24 because there are 24 possibilities in total, and we are looking for the probability of getting those 2 combinations.

I simplified 2/24 to its lowest form and I got 2/24 = 1/12.

So the correct answer is C.1/12, hope this helps!

Graph the system of equations. {2x−y=4x−y=−2 Use the Line tool to graph the lines.

Answers

Hear hear! For I have brought you the correct answer... (I took a "snip" of it so you can't see the entire graph but you can see the whole answer.)


By plotting the lines 2x - y = 4 and x - y = -2 using a graphing tool or on graph paper.

To graph these lines, you can start by rearranging them into slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.

For 2x - y = 4:

-y = -2x + 4

y = 2x - 4

This equation has a slope of 2 and a y-intercept of -4.

For x - y = -2:

-y = -x - 2

y = x + 2

This equation has a slope of 1 and a y-intercept of 2.

Now, you can graph these lines on a coordinate plane by plotting the y-intercepts and using the slopes to find additional points.

Once you have the two lines graphed, their point of intersection represents the solution to the system of equations.

A school baseball team earned $3416.90 from selling 5716 tickets to their game. If grandstand tickets sold for 65 cents each and bleacher tickets sold for 40 cents each, how many of the bleacher tickets were sold?

Answers

does any previous problem tell you how many grandstand tickets were sold?

Let x and y represent the number of grandstand and bleacher tickets sold respectively.

We know that the total number of tickets sold is 5716. Therefore, we will get the equation:

x+y = 5716

Therefore, x=5716-y.............................(Equation 1)

Now, we also know that the total value of tickets sold is $3416.90 or 341690 Cents.

We also know that the price of one grandstand ticket is 65 Cents. Thus, the price of x grandstand tickets will be 65x cents.

Likewise, since the price of one bleacher ticket is 40 cents, the price of y bleacher tickets will be 40y cents.

The information presented above gives us:

65x+40y=341690..........................(Equation 2)

Substituting x from (Equation 1) to (Equation 2) we get:

[tex] 65(5716-y)+40y=341690 [/tex]

Let us solve the above equation for y.

[tex] 65\times 5716-65y+40y=341690 [/tex]

[tex] 371540-25y=341690 [/tex]

[tex] \therefore 25y=371540-341690=29850 [/tex]

[tex] y=1194 [/tex]

Therefore, the total number of bleacher tickets sold was 1194.


A salesperson receives a 3% commission on sales. The salesperson receives $180 in commission. What is the amount of sales?

Answers

Hello there! We are looking for the amount of total sales. To find the amount of total sales, we can write and solve a proportion. Set it up like this:

180/x = 3/100

We do this, because 180 is part of the whole, 3% is a part of 100%. This proportion will help us get to the correct answer. Let's cross multiply. 180 * 100 is 18,000. 3 * x is 3x. that makes 18,000 = 3x. Now, divide each side by 3 to isolate the x. 3x/3 cancels out. 18,000/3 is 6,000. Let's check this. 6,000 * 3% (0.030 is 180. 180 = 180. There. x = 6,000. The amount of sales is $6,000.
The amount of sales is $6,000.

The top and bottom areas of the base cuboid are (10 in)*(10 in) = 100 in^2, for a total of 2*100 in^2 = 200 in^2.

The lateral area of the base cuboid is its perimeter (4*10 in = 40 in) multiplied by its height (2 in), so is 80 in^2.

Likewise, the lateral area of the "tower" is the product of its perimeter (4*5 in = 20 in) and its height (8 in), so is 160 in^2.

4x = 24
x = 24/4
x = 6

AC = 4x+17
      = 4*6 + 17
      = 24 +17
      = 41°

Answer:

The measure of AC is 41°

Step-by-step explanation:

Given : ∠ABC = (4x-3.5)°

            Arc AC = (4x+17)°

An inscribed angle: An angle with its vertex on the circle and whose sides are chords.

The intercepted arc : The arc that is inside the inscribed angle and whose endpoints are on the angle.

The Inscribed Angle Theorem : The measure of an inscribed angle is half the measure of its intercepted arc.

Uisng the theorem

[tex]\angle{ABC}=\frac{1}{2} \text{arc(AC)}[/tex]

[tex](4x-3.5)^{\circ}=\frac{1}{2} (4x+17)^{\circ}[/tex]

[tex]2*(4x-3.5)^{\circ}= (4x+17)^{\circ}[/tex]

[tex]8x-7= 4x+17[/tex]

[tex]4x=24[/tex]

[tex]x=\frac{24}{4}[/tex]

So, Arc AC = (4x+17)° = (4*6+17)° = (24+17)° = 41°

Hence the measure of AC is 41°
