Answer: Multiplying a large number can be easier if you break it up into its place values and perform the multiplication separately for each place value.

Step-by-step explanation:

Take the following multiplication issue, for instance:

43 x 32

The issue arises if place value is used to divide the numbers:

(4 x 3) + (3 x 2) + (3 x 3) (3 x 3)

This can be stated simply as:

12 + 6 + 9 = 27

Thus, the final response is 27.

Breaking up the multiplication problem by place value can also help you avoid making mistakes because you can check each place value separately to make sure that the calculations are correct before adding them together to get the final answer.

Answer:

13. x=4

14. x=8

Step-by-step explanation:

We know that these are both isosceles triangle because the two base angles are the same on #13, and the two sides are the congruent on #14. So all we need to do is make equations of equivalence. So #13 9x-8=28 and #14 11x-18=70. Look at the work shown in the image and follow those steps.

We have prepared the table and drawn the graph.

What is a graph of a function?

A graph of a function is a visual representation of the relationship between the inputs (x-coordinates) and the outputs (y-coordinates) of a function. The inputs are typically represented on the x-axis and the outputs are represented on the y-axis.

Table:

x (days) y (number of cells)

0        1000

1        2000

2       4000

Graph:

The graph would be a line graph with x-axis showing the day passed and y-axis showing the number of bacteria cells,

The point (0,1000) would be plotted on the graph, representing the initial number of bacteria cells on the first day.

The point (1,2000) would be plotted on the graph, representing the second day and the number of bacteria cells.

The point (2,4000) would be plotted on the graph, representing the third day and the number of bacteria cells.

The graph would be a upward sloping line, representing the growth of bacteria cells.

Hence we have prepared the table and drawn the graph.

The Boolean expression A >= B is equivalent to  !(A < B) (option A)

To simplify a Boolean expression, use De Morgan's Law.

De Morgan's Law is used to simplify or find the equivalent of a negation of compound expressions.

The principle is:

NOT (A AND B) is equivalent to (NOT A) OR (NOT B)

NOT (A OR B) is equivalent to (NOT A) AND (NOT B)

When the expression involves >, <, = signs, then to simplify the expression, move the not and flip the sign.

! is the symbol of negation or NOT.

Hence,

! (>) becomes <=

! (<) becomes >=

Here are some examples:

!(A > B) is equivalent to (A <= B)

!(A <= B) is equivalent to (A > B)

!(A >= B) is equivalent to (A < B)

!(A == B) is equivalent to (A != B)

!(A != B) is equivalent to (A == B)

!(A < B) is equivalent to (A >= B)

From the above list we can conclude that A >= B is equivalent to !(A < B) (option A)

Answer:

q = ± 5[tex]\sqrt{5}[/tex]

Step-by-step explanation:

f(q) = q² - 125

to find the roots , let f(q) = 0 , that is

q² - 125 = 0 ( add 125 to both sides )

q² = 125 ( take square root of both sides )

q = ± [tex]\sqrt{125}[/tex]  = ± [tex]\sqrt{25(5)}[/tex] = ± ([tex]\sqrt{25}[/tex] × [tex]\sqrt{5}[/tex] ) = ± 5[tex]\sqrt{5}[/tex]

A child's ticket would cost $10 while and adult's ticket would cost $18.

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power. In other words, none of the exponents can be greater than 1.

For example, x² is a variable raised to the second power, but x is a variable raised to the first power.

5 is an example of a constant.

The expressions are;

3a + 4c = 94 ---- 1

2a + 3c = 66 ---- 2

Multiplying equation 1 by 2 and equation 2 by 3

6a + 8c = 188 ---- 3

6a + 9c = 198 ---- 4

--------------------------

     - c = - 10

therefore;

c = 10

Substituting c in equation 3

6a + 8(10) = 188

6a + 80 = 188

6a = 188 - 80

6a = 108

a = 18

Therefore, child's ticket costs $10 while and adult's ticket cost $18.

The inequality which can be used to determine x is equal to 78.20x ≤ 304.98 , and the number of outfits Madeline can purchase while staying within her budget is 3  .

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Given that Total money Madeline can spend = $680

Price of the cycle = $318.67

Price of 2 pair of reflectors = 2x 12.89 = $25.78

Price of a pair of bike gloves = $30.57

It can calculated as Money left with Madeline = (Total money Madeline has ) - price of the cycle - price of 2 pair of reflectors - price of a pair of bike gloves

Thus Money left with Madeline = 680 - 318.67 - 25.78 - 30.57

                                          = $304.98

Consider Madeline purchase x number of  biking outfits

The price of each biking outfit = $78.20

The price of x biking outfit = 78.20x

Since Madeline has only $304.98 She can only use not more than $304.98.

The inequality becomes

78.20x ≤ 304.98

Solving for x we get;

x ≤ 304.98/78.20

x ≤ 3.9

A statement which correctly describes the comparison between the shapes of the box plots include the following: A. The Bulldogs' distribution is symmetric, but the Wolverines' distribution is negatively skewed.

In Mathematics, skewness can be defined as a measure of the asymmetry of a box plot (box-and-whisker plot) or histogram and as such, a box plot (box-and-whisker plot) or histogram has a normal distribution when it is symmetrical.

By critically observing the box plot (box-and-whisker plot) which represent basketball scores for the Bulldogs basketball team has a median of 80 (vertical line dividing the box into two equal halves), which simply means that both whiskers on either sides of the box plot (box-and-whisker plot) are relatively equal and symmetric.

On the other hand (conversely), the box plot (box-and-whisker plot) for the Wolverines basketball team shows that the median is more closer to the third quartile (upper quartile) and the whisker to the right of the box plot is longer, which ultimately implies that Wolverines' distribution is negatively skewed.

We can notice that this is a quadrilateral with two pairs of equal sides, with that we will see that:

m∠D = 98°

In the image we can see a quadrilateral ABCD, on that image we can see that:

AB = CD

AD = BC

You can notice that because of the "arrows" on the sides.

From that, we can conclude that the measures of the angles meet the conditions:

m∠A = m∠C

m∠D = m∠B

On the image we also can see that:

m∠B = 98°

And the measure of angle B is equal to the measure of angle D, then we can conclude that the measure of angle D is also 98°, so:

Here x refers the missing number of chicken nuggets.

Then the equation is written as

=> 1 + 3 + 0 + 6 + x = 10 + x

Here we can multiply both sides by 5 to clear the denominator:

Then we have to isolate the x by subtracting 10 from both sides.

The cultivation of maize affected the settlement patterns in the American Southwest and present-day Mexico as B. It caused Native Americans in the area to develop permanent settlements supported by farming and irrigation system

The cultivation of maize had a significant impact on settlement patterns in the American Southwest and present-day Mexico. In the American Southwest, the cultivation of maize, along with other crops such as beans and squash, allowed for the development of more permanent settlements as people were able to rely on a stable food supply. This, in turn, led to the growth of larger, more complex societies and the development of elaborate systems of trade and exchange.

In present-day Mexico, the cultivation of maize played a central role in the development of complex societies such as the Olmec, Maya, and Aztec. These societies built sophisticated systems of agriculture, including terracing, irrigation, and crop rotation, which allowed them to support large populations and build elaborate cities. The cultivation of maize was also closely tied to the religious and cultural practices of these societies, and it played a central role in their economies and social systems.

First, we can set up the ratio of carrots to potatoes as 3:4. Since there are 12 carrots, we can set up the following proportion:

3/4 = 12/x

To solve for the number of potatoes, we can cross-multiply to get:

4x = 12 * 4

x = 48/4

x = <<48/4=12>>12 potatoes.

Therefore, there are 12 potatoes in the sack.
