What does a mathematical expression mean?

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation.

This mathematical operation may be addition, subtraction, multiplication, or division.

Given expression is 20x + 12 = 4(_+_). The value of the missing terms will be calculated as,

2( 6 + x)

Lucille has an aquarium with 9 gallons of water which weighs 85 pounds. The stand holding the aquarium can hold no more than 112 pounds. She wants to add 2.5-pound rocks, r, her tank. Complete the inequality to show how many rocks she can add. R≤

Answers

Answer:

[tex]r\leq 10.8[/tex]

[tex]r\leq 10[/tex]

Step-by-step explanation:

Given that:

Amount of water in the aquarium = 9 gallons

Weight of water in the aquarium = 85 pounds

Total weight that aquarium can hold = 112 pounds

Weight of each rock = 2.5 pounds

To find:

The inequality to find the number of rocks, [tex]r[/tex] that can put in her tank.

Solution:

First of all, let us find more weight that the aquarium can hold after putting the water in the aquarium.

Additional weight that can be put in the aquarium = Total weight - Weight of water = 112 - 85 = 27 pounds

This 27 pounds can be of rocks.

Let the number of rocks that can be put in the aquarium = [tex]r[/tex]

Total weight of [tex]r[/tex] number of rocks = Weight of one rock multiplied by [tex]r[/tex]=2.5[tex]r[/tex]

Now, this weight of rocks must be lesser than or equal to 27 pounds.

Therefore, the in equality is:

[tex]2.5r\leq =27\\\Rightarrow r \leq 10.8\\OR\\\Rightarrow r \leq 10[/tex]

What is the first step to solving the following equation?5x –11 = 42

Answers

Answer:

add the 11 to both sides to cancel it out.

Step-by-step explanation:

so basically

5x - 11 + 11 = 42 +11

5x = 53

The required first step of solving the given expression is to add 11 on both sides.

Given that,
The first step for the solution of the given expression 5x - 11 = 42 is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
5x - 11 = 42
Add 11 on both sides to reduce the equation as
5x = 53

Thus, the required first step of solving the given expression is to add 11 on both sides.

The formula for the volume, V, of a shape is given by V = Ah. A is the area and h is the height.
(a) Find the volume of the shape if A = 40 and h = 8
(b) Find the area of the shape if V= 800 and h = 20

Answers

Answer:

Step-by-step explanation:

a) V= A*h V=40*8=320

b) V=800 and h=20

A=V/h=800/20=40

Answer:

see explanation

Step-by-step explanation:

Given the formula

V = Ah

with A = 40 and h = 8 , then

V = 40 × 8 = 320 units³

(b)

Given V = 800 and h = 20, then

800 = 20A ( divide both sides by 20 )

A = 40 units²

The weights of dogs at a kennel are Normally distributed with a mean of 18 pounds and a standard deviation of 3.5 pounds.In which percentile is a dog who weighs 25 pounds?

Answers

Answer:

P(x=25)=P(z=2)=0.9972 or 99.72%

Step-by-step explanation:

Mean = 18 pounds

Standard Deviation = 3.5 pounds

x= 25

We need to find P(x=25)

First, we need to find z-score using formula: [tex]z-score=\frac{x-\mu}{\sigma}[/tex]

Finding z-score when x=25

[tex]z-score=\frac{x-\mu}{\sigma}\\z-score=\frac{25-18}{3.5}\\z-score=2[/tex]

So, we need to find P(z=2)=P(x=25)

Looking at z-score table we can find P(z=2)

P(z=2)=0.9972 or 99.72%

So, P(z=2)=0.9972 or 99.72%

Answer:

97.5th percentile
