Final answer:

To spot Sienna's error in using base-ten blocks for dividing 45 by 3, we need to verify the even distribution of tens and ones among three groups. The correct result should be 15, with each group receiving 1 ten block and 5 ones blocks.

Explanation:

To find the error made by Sienna in dividing 45 by 3 using base-ten blocks, we need to visualize the process. The number 45 consists of 4 tens (which are blocks representing the number 10) and 5 ones (single blocks representing the number 1). Since she is dividing by 3, Sienna should group the blocks into 3 equal groups to find the quotient, which should be the same number in each group when the blocks are divided evenly.

If Sienna were to correctly divide the blocks to find 45 ÷ 3, she would need to distribute the 4 tens blocks evenly among 3 groups, which would give each group one ten blocks, with one ten blocks remaining. These remaining ten blocks should then be exchanged for ten one's blocks, which, added to the existing five one's blocks, makes a total of fifteen one's blocks. These fifteen blocks can then be evenly distributed, giving each group five blocks. In the end, each group will have one ten-block and five blocks, meaning the quotient is 15.

Therefore, the error that Sienna could have made could include not exchanging a remaining tens block for ones blocks, or not distributing the ones blocks correctly after exchanging. It’s important to keep track of remainders and ensure even distribution among the groups to find the correct quotient in division with base-ten blocks.

The distance function for Aubrey and Charlie's trip is d(t) = 20 + 50t, accounting for an initial 20 miles already traveled. The reasonable domain for time t in this situation is from 0 to 2 hours since they are traveling at 50 miles per hour and have 100 miles remaining.

Aubrey and Charlie have already traveled 20 miles and are continuing to travel towards a city that is 120 miles away from their start at a constant rate of 50 miles per hour. To complete the function that models the distance they drive as a function of time, we use the formula distance traveled is velocity  imes time. With a start of 20 miles, the function can be written as:

d(t) = 20 + 50t

Where d(t) represents the distance traveled at time t in hours. For the domain, since they have already traveled 20 miles, the remaining distance is 100 miles. At a rate of 50 miles/hour, the maximum time needed to cover the remaining distance is 2 hours. Hence, the reasonable domain for time t is 0 ≤ t ≤ 2.

The edge length of a Rubik's cube, given a face perimeter of 22.2 cm is 5.55 cm.

The question asks for the length of an edge of a Rubik's cube, given that the perimeter of each face of the cube is 22.2 cm. A Rubik's cube is a square based cube, meaning each face of the cube is a square.

In a square, all sides have equal length and the perimeter is four times the length of one edge. Therefore, to find the length of one edge, you divide the perimeter of the square by four. Using the provided perimeter of 22.2 cm, the length of an edge would be 22.2 ÷ 4 = 5.55 cm

Answer:

Slope of the line is 4 and the point on the line is (-8,3)

Step-by-step explanation:

The equation of the line is given by [tex]y-3=4(x+8)[/tex]

The point slope form of a line is

[tex]y-y_1=m(x-x_1)[/tex]

Here, m is the slope of the line

And the point [tex](x_1,y_1)[/tex] lies on the line.

On comparing the given equation with the point slope form of the line

[tex]m=4,x_1=-8,y_1=3[/tex]

Therefore, the slope is 4 and the point on the line is (-8,3)

The slope of the equation is 4, and a point on the line is (0,35)

The equation is given as:

[tex]y - 3 = 4(x + 8)[/tex]

Open the bracket

[tex]y - 3 = 4x + 32[/tex]

Add 3 to both sides

[tex]y = 4x + 35[/tex]

A linear equation is represented as:

y = mx + b

Where m represents the slope

So, by comparison:

The slope of the equation is 4

Set x = 0

y  = 4 * 0 + 35

y = 35

Hence, a point on the line is (0,35)

To solve problems with integers and rational numbers, one should apply operations' properties such as commutativity, associativity, and distributivity, which streamline calculations and assist in combining numbers in an order that simplifies the process.

Integers and rational numbers are essential elements of algebra that allow for diverse mathematical operations. Integers are the set of whole numbers including zero, and their negative counterparts (e.g., -1, 0, 1), while rational numbers are ratios of integers (e.g., 2/1, 3/4) that can represent fractions and decimals that terminate or repeat. When solving problems, it is crucial to remember the properties of operations, which include commutativity associativity , distributivity, the additive inverse and the multiplicative inverse.

For example, when adding fractions with different denominators, you find a common denominator and use commutativity and associativity to combine these fractions. A problem involving multiplication of a negative integer and a fraction may require both the distributive property and understanding of the multiplicative inverse. Mastering these properties provides a foundation for solving algebraic expressions and equations, ensuring accuracy whether the numbers are complex, real, rational, or integers.

Final answer:

The product of 7/8 and 8 is the multiplication of a fraction by a whole number, leading to the simplified result of 7. This is because multiplying by 8/8 (which equals 1) does not change the original numerator of the fraction.

Explanation:

When we talk about the product of 7/8 and 8, we are performing a multiplication between a fraction and a whole number. To do this, you can multiply the numerator of the fraction by the whole number and leave the denominator unchanged. Since 7/8 multiplied by 8/1 is the same as 7/8 times 8, you can simplify the equation by multiplying 7 by 8, which gives you 56, and then divide that by the denominator, which is 8. So, the product is 56/8, which simplifies to 7. This is because 8/8 is essentially 1, and multiplying by 1 doesn't change the value of the number, thus the product of 7/8 and 8 is the same as the numerator 7.

Use 1.75 cups of blue and 1 cup of yellow

The given problem can be placed in the category of ratios and proportions. There is a ratio of color mixing which contains the proportion of two colors i.e blue and yellow. When we use 2 cups of yellow with 3.5 cups of yellow then we get green color so if we mix half of their amounts then we can get less or simply half amount of color too. Hence adding 1 cup of yellow and 1.75 cup of blue will give us small amount in result.

[tex]3.28084 feet = 1 meter[/tex]

So,

[tex]1 feet = \frac{1}{3.28084} meter[/tex]

[tex]1 cubic feet= \frac{1}{3.28084} *\frac{1}{3.28084}* \frac{1}{3.28084}cubic meters[/tex]
