Answer:

The number of ways to assing 7 floors to 5 passengers is 7⋅7⋅7⋅7⋅7

Step-by-step explanation:

The probability that, after 5 seconds, the elevator is at floor 18 is 16807.

Every second, an elevator either has a 50% chance of going up or a 50% chance of going down.

If the elevator starts on floor 15.

An act of arranging; state of being arranged

The number of ways to assign 7 floors to 5 passengers is,

Answer:

x=-2

y=9

Step-by-step explanation:

Multiply one of the equations to get negative terms with equal y coefficients. Add them together then solve for x.

Substitute x in one of the equations then solve for y.

You can check your answer by substituting x and y into one equation and solving to obtain the same answer on the right side of the equation.

Step-by-step explanation:

-4 < -1

Note:

< → Less than

> → Greater than

= → Equal

Explain:

if you put -4 and -1 on a number line it on the left. But -4 is more on the left than -1. Thus, we can know that -4 is less than -1.

Answer: 45%.

Step-by-step explanation: When you solve problems like these, you need to make the total 100%.  The total amount of people at the community pool is 120.  120 can be our 100%.  66 people aren't in the water and 54 are in the water.  As you can see, less than half of the total number of people at the community swimming pool is in the water, which means that is 45%.  The 66 people who aren't in the water are 55% of the total people that are at the community swimming pool.  So in summary, 45% of the total people who are in the community swimming pool are in the water.

Answer:

Answer:
The width of member is as follows:
b = 3 ft

b = 3 × 12 in.

b= 36 in.
The depth of member is as follows:

d = 8 ft

d = 8 × 12 in.

d=96 in.
Since the structure used is Douglas fir-Larch lumber of size 3 × 8 size. Hence, tensile strength, f =1000 psi
Calculate the net area of the member as follows:
A = (b - ∅) × d

A= (36 - 7/8) × 96
[tex]A = 3372in^{2}[/tex]
Calculate the maximum axial tensile load by ASD method as follows:
P = f × A

P = 1000 x 3372

P = 3372000 lbs  
P = 3372 kips

Answer:

Perameter = 22

Area = 30

Answer:

Step-by-step explanation:

A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit).

Since the key says 4|0= 40 the answer to your question is 12. Twelve cleaners have more than 80 ingredients.

Answer: 12.

Step-by-step explanation: According to the key, 4|0 means 40, which applies to any other stem and leaf on the chart.  For example, on the chart, any numbers to the other side of the 8 are more than 0 which can be 8|2 or 8|5, so those count.  9|0 or 90, is way bigger than 80, so any numbers next to 90 count as well.  I circled all the numbers that are correct, which is 12.

Answer:

Question 3

In 15 minutes, the tortoise walked 400 meters

1 hour ---> 60 minutes

60 minutes is 4 x 15 minutes

4 x 15 // 400 x 4

1 hour // 1600 meters = 1.6 kilometers

the tortoise can walk 1.6 Kilometers per hour

Question 4

2 quart bottle for 2.56$

1 quart = 32 fluid ounces

2 quart = 64 fluid ounces

2.56/64 = 0.04$ per fluid ounce

Answer:

  $61.25

Step-by-step explanation:

The quantity for a 60-day supply is 60 times the 1-day usage. The BOGO offer means the sale price is effectively half the usual price.

__

One day supply: 2/3 can + 1/2 can = (4/6 +3/6) = 7/6 can

60-day supply: 60 × 7/6 can = 70 cans

Susan will be paying for 70/2 = 35 cans of dog food. (She will get 35 cans free.) So, her cost will be ...

  35 × $1.75 = $61.25

The cost of Susan's dog food purchase would be $61.25 before tax.

Step-by-step explanation:

The volume of prism is,

⇒ V = 126 yards²

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A right prism has a triangular base. The length of the base is 12 yards and the height of the base is 3 yards. The height of the prism is 3.5 yards.

We know that;

The volume of prism is,

⇒ V = B × H

Where,  B is the area of the base and h is the height of the prism.

Hence, We get;

The volume of prism is,

⇒ V = 12 × 3 × 3.5

⇒ V = 126 yards²

Thus, The volume of prism is,

⇒ V = 126 yards²

Answer:

32

Step-by-step explanation:

If the question is x (standing for an unknown number) divided by 4 equals 8, then 8 times 4 should equal that unknown number.

x / 4 = 8

x / 4 (*4) = 8 (*4)

x = 32

We now can replace x with our number and see if this answer is valid.

x / 4 = 8

32 / 4 = 8

And yes, it is true. Therefore, 32 divided by 4 is 8.

Answer:

x ≤ 40

Step-by-step explanation:

Given:

[tex]\displaystyle \large{\dfrac{x}{-8} \geq -5}[/tex]

Multiply both sides by -8 to get clear out the denominator:

[tex]\displaystyle \large{\dfrac{x}{-8}\cdot (-8) \geq -5\cdot (-8)}\\\displaystyle \large{x\geq 40}[/tex]

Because the LHS (Left-Handed Side) expression is in negative, make sure not to forget to swap the sign from ≥ to ≤

Hence, the solution is x ≤ 40
