Step-by-step explanation:

4z - 32 = 36

4z = 68

z = 17

6x - 29 = 115

6x = 144

x = 24

36 + 115 = 151

What is the probability that a randomly selected customer likes hot or iced coffee?

A.

B.

C.

D

Answers

Answer:

0.83

Step-by-step explanation:

add the hot, cold, and both sections together

xoxo, your highness...

The probability of people liking hot or iced coffee is 0.61. Therefore, option C is the correct answer.

What is the probability?

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, according to sales records at a local coffee shop, 75% of all customers like hot coffee, 30% like cold coffee and 22% like both hot and iced coffee.

People like only hot coffee = 0.53

People like only iced coffee = 0.08

Customers like hot or iced coffee =0.53+0.08

= 0.61

Therefore, option C is the correct answer.

The height of XYZ is the distance from the point Y to XZ find the area of the triangle round your answer to the nearest 10th if necessary HELPPP PLEASE

Answers

Answer:

Area of ΔXYZ = 10 square units

Step-by-step explanation:

Area of the triangle XYZ = [tex]\frac{1}{2}(\text{Height})(\text{Base})[/tex]

Height of the triangle = AY

Base of the triangle = XZ

To get the length of any segment we will use the formula,

d = [tex]\sqrt{(y_2-y_1)^2+(x_2-x_1)^2)}[/tex]

Here [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the endpoints of the segment.

Length of AY = Distance between (-1, 4) and (3, 6)

                      = [tex]\sqrt{(6-4)^2+(3+1)^2}[/tex]

                      = [tex]\sqrt{20}[/tex]

Length of XZ = [tex]\sqrt{(6-2)^2+(-2-0)^2}[/tex]

Step-by-step explanation:

First Degree Equations

A first-degree equation can have one, none, or infinitely many solutions.

An equation like

2x + 3 = -x + 6

Has one solution: x=1

An equation like:

4x + 2 = 4x + 1

Has no solutions because when trying to solve for x we get:

2 = 1

This equality is false and no value of x can make it true

Finally, the equation:

3x + 2 = x + 2x + 2

Has infiniteyl many solutions, because when trying to solve it, we get:

2 = 2

Which is true regardless of the value of x

The first given equation:

3x + 9 + 4x + x = ??

can be simplified as:

8x + 9 = ??

For this equation not having solutions, we should have 8x plus any number but 9 on the right side of the equation:

8x + 9 = 8x -3, or

8x + 9 = 8x + 4

The second given equation:

3x + 9 + 4x + x = ??

can be simplified as:

8x + 9 = ??

If the equation has one solution, the only condition is that we should not have 8x on the right side. Thus any of those will do:

8x + 9 = 3x + 9

8x + 9 = -x + 5

8x + 9 = 0

The third equation:

3x + 9 + 4x + x = ??

can be simplified as:

8x + 9 = ??

For this equation to have infinitely many solutions, the right side must be exactly equal to the left side:

8x + 9 = 8x + 9

Solve for the distance between the points (0, -9) and (-4, 3).

Jane is a computer science major planning to take 4 courses next semester. She is planning to take 2 computer science courses and 2 courses from other areas. How many different schedules can she build?

Answers

Answer: 24 schedules.

Step-by-step explanation:

Given data:

Courses planning to take = 4

Computer courses = 2

Courses from other areas = 2

Solution:

This problem can be solved using permutation.

For Computer science courses.

npr = n! / ( n - r )!

Where n = 4

r = 2

4p2 = 4!/( 4-2)!

= 4!/2!

= 12

For other courses.

Where n = 4

r = 2

4p2 = 4!/( 4-2)!

= 4!/2!

= 12

Jane can have a total of 24 different schedules.

You and your four friends have $25 to spend on snacks. A medium size popcorn costs $2.50 and a medium soft drink costs $1.50. Write and graph an inequality that represents the numbers of medium boxes of popcorn and medium soft drinks you can buy.

Answer:

Step-by-step explanation:

Step one:

given

Total money at hand=$25

cost of one popcorn=n $2.5

cost of drink= $1.5

total number of friends plus you= 4+1= 5

let the total amount spent be y

y= 5(2.5)+5(1.5)

y=12.5+7.5

y=20

a company makes two different-sized ice cream cones. The smaller cones are 3.5 inches tall and have a diameter of 3 inches. The larger cones are 5.1 inches tall and have a diameter of 4.5. inches. About how much greater, to the nearest tenth of a cubic inch, is the volume of the larger cone than the volume of the smaller cone?

Answers

9514 1404 393

Answer:

  18.8 cubic inches

Step-by-step explanation:

The formula for the volume of a cone is useful:

  V = 1/3πr²h

Where r is half the diameter, we can use r=d/2 to write this in terms of diameter:

  V = 1/3π(d/2)²h = (π/12)d²h

For the given dimensions, the volumes are ...

  large cone: v = (π/12)(4.5 in)²(5.1 in) ≈ 27.04 in³

  small cone: v = (π/12)(3 in)²(3.5 in) ≈ 8.25 in³

Then the difference in volume is ...

  (27.04 -8.25) in³ ≈ 18.8 in³

The larger cone has about 18.8 cubic inches more volume.

A person 6ft tall stands 10ft from point P directly beneath a lantern hanging 30 ft above the ground. The lantern start to fall, thus causing the person shadow to lengthen(L). Given that the lantern falls 16t2 feet in t seconds, how fast will the shadow be lengthening when t=1

Answers

Answer:

[tex]\frac{dL}{dt}=30 \frac{ft}{s}[/tex]

Step-by-step explanation:

In order to solve this it is always a good idea to start by drawing a diagram of the situation (See attached picture).

From the diagram we can see that we are dealing with similar triangles. We can use similar triangles to build an equation that relates the length of the shadow with the height of the lamp, so we get:

[tex]\frac{L}{6}=\frac{10+L}{h}[/tex]

the height of the lamp can be found by subtracting the [tex]16t^{2}[/tex] distance the lamp falls in a given time t from the original 30ft the lamp was located at.

So the equation will now lok like this:

[tex]\frac{L}{6}=\frac{10+L}{30-16t^{2}}[/tex]

So now we can solve the equation for L, we can start by multiplying by the LCD SO WE GET:

[tex]L(30-16t^{2})=6(10+L)[/tex]

next, we can distribute the right side of the equation so we get:

[tex]L(30-16t^{2})=60+6L[/tex]

and subtract 6L from both sides so we get:

[tex]L(30-16t^{2})-6L=60[/tex]

and factor L, so we get:

[tex]L(30-16t^{2}-6)=60[/tex]

and solve for L:

[tex]L=\frac{60}{24-16t^{2}}[/tex]

now, we can differentiate this equation by using the chain rule, so we get:

[tex]dL=-\frac{60}{(24-16t^{2})^{2}}(-32t)dt[/tex]

which can be simplified to:

[tex]\frac{dL}{dt}=\frac{1920t}{(24-16t^{2})^{2}}[/tex]

and now we can substitute t for 1s so we get:

[tex]\frac{dL}{dt}=\frac{1920(1)}{(24-16(1)^{2})^{2}}[/tex]

[tex]\frac{dL}{dt}=30 \frac{ft}{s}[/tex]

He would have to work at building up his endurance and set more realistic goals for himself. As he thought about what he had already accomplished, he started to smile and felt like a weight was being lifted off his shoulders. He realized that he had run almost a mile and a half before his body started to protest and if he kept working hard, he could get back to where he was before his accident.Since when did you get so smart, Dr. Meiya? he teased.
