We have to find that Clara is correct or not.
What is expressions ?
Expression in math is a phrase that can contain numbers ( 1, 2, 3 etc.), variables ( x, y, z etc.) and operators
Now,
Clara says that if you square the number 4 and then divide the result 2, you end up with 4.
If we square the number 4 we get,
[tex]4^{2} = 16[/tex]
And, then divide by 2,
[tex]\frac{16}{2} = 8[/tex]

it rounded to the nearest dime what is the greatest amount of money that rounds to $105.40
Answer:
$105.44.
Step-by-step explanation:
We are asked to find the the greatest amount of money that rounds to $105.40, rounded to the nearest dime.
We know that when the next digit to rounded digit is 0, 1, 2, 3, 4; then we keep the same digit.
When the next digit to rounded digit is 5 or more than 5; then we round up our answer by one digit.
We know that 1 dime equals $0.10.
Since our answer in rounded to nearest dime, so the hundredths digit will be less than 5.
Therefore, the greatest amount of money would be $105.44.
the rivers family plans to travel to the beach for a summer vacation the family spend 67.50 for 23 gallons of gasoline the distance between their home and the beach is approximately 350 miles to the nearest cent how much money did the rivers family spend per gallon on gas for the trip
To find the cost per gallon of gasoline for the Rivers family, we divide the total amount spent on gas ($67.50) by the total number of gallons purchased (23). This gives us an approximate cost of $2.93 per gallon for their trip to the beach.
Explanation:A common way to analyze such problems is to determine the cost per unit, in this case, the cost per gallon of gasoline. The Rivers family spent $67.50 on 23 gallons of gasoline. To figure out how much they spent for each gallon of gasoline, we divide the total cost by the quantity of gallons.
So, the calculation is $67.50 / 23 gallons, which is approximately $2.93 per gallon. Hence, for this trip to the beach, the Rivers family was spending around $2.93 for each gallon of gasoline they purchased.

The question involves the division of decimal numbers by whole numbers. The results are 2.06, 21.3, 5.41, and approximately 2.96, respectively. For calculations, the decimal point in the quotient is aligned with the decimal point in the dividend.
Explanation:Division of Decimal Numbers
The given question involves the division of decimal numbers by whole numbers. These operations can be easily performed using long division or a calculator:
16.48 divided by 8 equals 2.06.191.7 divided by 9 equals 21.3.21.64 divided by 4 equals 5.41.41.44 divided by 14 equals approximately 2.96.To perform these divisions, place a decimal point in the quotient (the result) directly above the decimal point in the dividend (the number being divided). Then, proceed with the division as you would with whole numbers, bringing down the digits past the decimal point as necessary.

A 25-N net force is applied to a rolling cart and produces an acceleration of 5 m/s2.What is the cart's mass
The mass of the cart is 5 kg
The calculation can be done as follows
Force= 25 N
Acceleration= 5 m/s²
The mass can be calculated as follows
Force= mass × acceleration
25= mass × 5
mass= 25/5
= 5 kg
Hence the mass of the cart is 5 kg

Make an estimate for 3389+2712. Write a number model to show your strategy. I know the answer. Can someone explain this to me pls
Final answer:
To estimate the sum of 3389 and 2712, round each number to the nearest thousand (3389 to 3000 and 2712 to 3000) and then add them to get an estimated sum of 6000.
Explanation:
To make an estimate for the sum of 3389 and 2712, you can round each number to the nearest hundred or thousand then add the rounded numbers. In this case, let's round to the nearest thousand for a simpler estimate:
3389 is close to 3000 (rounded down)2712 is close to 3000 (rounded up)Now add the rounded numbers:
3000 + 3000 = 6000
The number model for this estimate strategy is:
\( 3000 + 3000 = 6000 \)
This model shows the process of rounding each term to the nearest thousand and then adding them together to get an estimated sum.

The markup from cost to sale price is $28.
Original selling price - $440Marked down by 30% to $440 - 30% = $308Markup from cost to sale price = Sale price - Cost price = $308 - $280 = $28Find the value of x so that the function has the given value .q(x)= 1/2x-3;q(x)=-4
To find the value of x when q(x) = -4, we set up the equation and solve for x.
Explanation:To find the value of x for which the function q(x) is equal to -4, we can set up the equation q(x) = -4 and solve for x.
Given q(x) = 1/2x - 3, we can substitute -4 for q(x) and solve:
-4 = 1/2x - 3
Adding 3 to both sides, we get:
-1 = 1/2x
Multiplying both sides by 2 to isolate x, we have:
-2 = x
Therefore, the value of x that makes the function q(x) equal to -4 is x = -2.

Cookies are sold singly or in packages of 10 or 30. With this packaging, how many ways can you buy 60 cookies?
To find how many ways you can buy 60 cookies using single cookies or packages of 10 or 30, you solve for non-negative integer solutions to the equation x + 10y + 30z = 60 and count the combinations.
Explanation:The question concerns the number of ways to purchase a specific quantity of an item when given different packaging options. Here, we want to find out how many ways you can buy 60 cookies when they are sold singly or in packages of 10 or 30.
To solve this, we can set up a mathematical equation where x, y, and z represent the number of single cookies, 10-cookie packages, and 30-cookie packages, respectively. The equation would be:
x + 10y + 30z = 60
We are looking for all non-negative integer solutions to this equation. By examining the possible combinations, we can systematically list out the ways to achieve the total of 60 cookies using these packaging options.
If we start by using no 30-cookie packages, we can have 0 to 6 packages of 10, with the remainder being single cookies.When using one 30-cookie package, we can have 0 to 3 packages of 10, with the remainder being single cookies.Lastly, if we use two 30-cookie packages, we don't need any 10-cookie packages, and we can just have 0 singles.By counting all the combinations, we can determine how many different ways there are to purchase exactly 60 cookies.

The true statement is b. Yes, the figure can be rotated 90°
Does the figure have rotational symmetry
From the question, we have the following parameters that can be used in our computation:
The figure (a square)
Rotational symmetry means that an object looks the same after a certain amount of rotation around a central point.
In the case of a square, it has rotational symmetry of 90 degrees. This means that if you rotate a square by 90 degrees (a quarter turn), it will look exactly the same as it did before the rotation.
Hence, the true statement is b. Yes, the figure can be rotated 90°

Solving the following problem -25 +37=
the table below shows the relationship between the approximate number of hours and the corresponding number of hours and the corresponding number of days on Saturn.
Answer: There are 768 hours in 72 days.
Step-by-step explanation:
Given: The number of hours in 25 days = [tex]266\frac{2}{3}=\frac{800}{3}[/tex] hours
Let x be the number of hours in 72 days.
Since the relation between number of hours and days is directly proportional, thus
[tex]\frac{x}{72}=\frac{\frac{800}{3}}{25}\\\Rightarrow\ x=\frac{800\times72}{3\times25}\\\Rightarrow\ x=768\text{ hours}[/tex]
Hence, there are 768 hours in 72 days.

Multivariate statistical techniques are a key tool used by scientists to find patterns in large data sets, allowing them to make predictions and understand relationships between variables.
One example of a tool that scientists use to find patterns in their data is multivariate statistical techniques. These techniques, often referred to as pattern analyses, are excellent at discovering and summarizing consistent patterns in large data sets. By applying these methods, scientists can identify cause and effect relationships, use graphs and charts to represent data visually, and make predictions based on the identified patterns.
Whether in biology, physics, or any other scientific field, finding patterns is essential for understanding relationships between variables, explaining general phenomena, and making meaningful predictions.
