To write down 4-digit odd and even numbers using the digits 7, 5, 4, and 8, there are 4 possible odd numbers and 2 possible even numbers.
Explanation:In order to write down all possible 4-digit odd and even numbers using the digits 7, 5, 4, and 8, we need to consider the following:
An odd number always ends with an odd digit, which in this case can only be 7 or 5. So, we have two options: 75 or 57.The remaining two digits can be arranged in any order. We have 2 options for the first digit (4 or 8) and 1 option for the second digit (the remaining digit).Therefore, for 4-digit odd numbers, we have a total of 2 * 2 * 1 = 4 possible numbers: 754, 584, 758, and 578.An even number always ends with an even digit, which in this case is 8. So, we need to choose an even digit for the thousands place. We have one option, which is 4. The remaining two digits can be arranged in any order.Therefore, for 4-digit even numbers, we have a total of 1 * 2 * 1 = 2 possible numbers: 854 and 584.I really need help with this problem thank you.
Charlie wants to order lunch for his friends. He'll order 6 sandwiches and a $2 kid's meal for his little brother. Charlie has $32. How much can he spend on each sandwich is they are all the same price?
Choose two answers: One for inequality that models this situation and one for the correct answer.
A. Inequality: 6x+2 > ( greater than or equal too ) 32
B. Inequality: 6x+2 < ( less than or equal too ) 32
C. Answer: $13 or less
D. Answer: $5 or less
E. Inequality: 2x+6 < 32
F. Inequality: 2x+6 < ( less than or equal too ) 32
Inequality that models the given situation is given by 6x+2 ≤ 32.
Price of each sandwich is equals to $5 or less.
What is inequality?" Inequality is defined as the algebraic expression which represents the relation between the variables using the sign of inequality < , > , ≤ , ≥."
According to the question,
Given,
Number of sandwiches = 6
Amount spend on kids meal = $2
Total money with Charlie = $32
'x' represents the cost of each sandwich
As per the condition inequality is given by,
[tex]6x+2 \leq 32\\\\\implies 6x \leq 32 - 2\\\\ \implies 6x \leq 30 \\\\ \implies x \leq \frac{30}{6} \\\\\implies x\leq \$5[/tex]
Hence, Option(D) is the correct answer

Helppppp! After 2 1/4 h, a chainsaw has used 2 13/16 gal of fuel.
How many gallons of fuel did the chainsaw use each hour?
Enter your answer as a mixed number in simplest form.
Answer:
[tex]1\frac{1}{4}[/tex]gallon/hour
Step-by-step explanation:
After [tex]2\frac{1}{4}[/tex] hour a chainsaw has used [tex]2\frac{13}{16}[/tex] gallons of fuel.
[tex]2\frac{1}{4}[/tex] hours = [tex]\frac{9}{4}[/tex] hours
[tex]2\frac{13}{16}[/tex] gallons = [tex]\frac{45}{16}[/tex] = 2.8125 gallons
The chainsaw used fuel after [tex]\frac{9}{4}[/tex] hours = [tex]\frac{45}{16}[/tex] gallons
The chainsaw used fuel in 1 hour = [tex]\frac{\frac{45}{16}}{\frac{9}{4}}[/tex]
= [tex]\frac{45}{16}[/tex] ÷ [tex]\frac{9}{4}[/tex]
= [tex]\frac{45}{16}[/tex] × [tex]\frac{4}{9}[/tex]
= [tex]\frac{180}{144}[/tex]
= [tex]\frac{90}{72}[/tex]
= [tex]\frac{30}{24}[/tex]
= [tex]\frac{15}{12}[/tex]
= [tex]\frac{5}{4}[/tex]
= [tex]1\frac{1}{4}[/tex] gallons of fuel
Chainsaw used [tex]1\frac{1}{4}[/tex] gallons of fuel in each hour

Explain how to model the multiplication of 3 and ‒4 on a number line
First, start at zero. Now, because we are multiplying -4 by 3, we will jump over by 4 to the left ; 3 times on the number line. We should reach -12, and if we check our work, 3 x -4 = -12.
Final answer:
To model the multiplication of 3 and -4 on a number line, start at zero and make three moves to the left by 4 units, ending up at -12. This demonstrates the rule that multiplying numbers with opposite signs results in a negative product.
Explanation:
To model the multiplication of 3 and -4 on a number line, you can follow these steps:
Start at zero on the number line.
Since you are multipling a positive number by a negative number, you will move in the negative direction (to the left).
Make three moves (corresponding to multiplying by 3), each 4 units to the left. This represents adding -4 three times.
Where you end up on the number line is the product of 3 and -4, which is -12.
This method of multiplication on a number line illustrates the rule that when two numbers multiplied have opposite signs, the answer has a negative sign, such as in the example ( -4) x 3 = -12.
Add using a number line.
5/6 + (−1 1/6)
Drag and drop the word SUM to the correct value on the number line.
Answer:
-1
Step-by-step explanation:
We are given that an expression
[tex]\frac{5}{6}-\frac{11}{6}[/tex]
We have to find the correct value of given expression on the number line.
[tex]\frac{11}{6}=1\frac{5}{6}[/tex]
[tex]\frac{5}{6}-\frac{11}{6}[/tex]
[tex]\frac{5-11}{6}=\frac{-6}{6}[/tex]
[tex]\frac{5}{6}-\frac{11}{6}=-1[/tex]
[tex]\frac{5}{6}+(-1\frac{5}{6})[/tex]
When an integer positive and other integer negative and add them .If negative integer is greater and positive integer is small then we go from left to right.
We go [tex]\frac{5}{6}[/tex] step from [tex]-1\frac{5}{6}[/tex]towards right then we reach at [tex]{-1}[/tex].
Hence, -1 is the correct value of given expression.

Stanley is putting wallpaper strips on his bathroom walls that have a total area of 460 ft2. Each strip of wallpaper covers 22 square feet. How many strips of wallpaper will Stanley need to fully cover his walls? Write your answer using the correct number of significant digits.
Answer:
21
Step-by-step explanation:
We are given that Stanley is putting wallpaper strips on his bathroom walls that have a total area of 460 square feet.
Area of each strip =22 square feet
We have to find the number of strips of wallpapers will Stanley need to fully cover his walls.
In order to find the number of strips of wall papers we are dividing the area of walls by area of each strips
Number of strips of wall paper=[tex]\frac{460}{22}[/tex]
Number of strips of wall paper=20.909 =21 strips of wallpaper
Hence, Stanley will need strips of wallpaper to cover fully his walls=21

A school library has 260 DVDs in its collection. Given that 45% of the DVDs are about science and 40% or about history how many of the DVDs are about other subjects?
39 DVDs are about other subjects.
To determine the number of DVDs about other subjects in the school library, we must first calculate the number of DVDs dedicated to science and history. We start by finding 45% of 260 DVDs for science and 40% of 260 DVDs for history.
Science DVDs: 45% of 260 = 0.45 * 260 = 117
History DVDs: 40% of 260 = 0.40 * 260 = 104
Adding the numbers of science and history DVDs gives us the total number of DVDs not about other subjects:
117 (Science) + 104 (History) = 221
To find the number about other subjects, we subtract the total number of science and history DVDs from the total collection:
260 (Total) - 221 (Science and History) = 39 DVDs about other subjects.

A company finds that on average, they use 43 minutes for each meeting.
An employee sketches a graph to show the total amount of time in minutes, T, used for m meetings. The graph shows the value of T for 1 to 5 meetings.
If the employee counts by 10's, what should be the largest value on the T-axis of his or her graph so that the scale is the most appropriate for the given information?
A. 10

C. 50
D. 200
E. 210
F. 220
G. 250
Answer:
F. 220
Step-by-step explanation:
Showing the time for 1 to 5 meetings means we would go from 43(1) = 43 to 43(5) = 215 for the y-axis (time in minutes).
We are counting by 10s. The two closest tens to 215 are 210 and 220. However, in order to show 215 on the graph, we must go up to 220.

The bar of chocolate should be broken [tex]\boxed{\bf 71\text{\bf\ times}}[/tex], so that it is separated into individual squares.
Further explanation:
Given that the bar of chocolate is eight pieces high and nine pieces long.
First break the chocolate horizontally [tex]7\text{ times}[/tex] since, it is eight pieces high.
Now, the broken piece of chocolate is divided into nine single strips of eight pieces each.
Each nine single strip is broken [tex]8\text{ times}[/tex].
Therefore, total number of times the chocolate bar is broken is calculated as follows:
[tex]\begin{aligned}\text{Total number of times}&=7+(8\cdot 8)\\&=7+64\\&=71\end{aliogned}[/tex]
Thus, [tex]71\text{ times}[/tex] the bar of chocolate is broken so that it is separated into individual squares.
Now, break the chocolate vertically [tex]8\text{ times}[/tex] since, it is nine pieces long.
Now, the broken piece of chocolate is divided into nine single strips of nine pieces each.
Each nine single strip is broken [tex]7\text{ times}[/tex].
Therefore, total number of times the chocolate bar is broken is calculated as follows:
[tex]\begin{aligned}\text{Total number of times}&=8+(9\cdot 7)\\&=8+63\\&=71\end{aliogned}[/tex]
Thus, [tex]71\text{ times}[/tex] the bar of chocolate is broken so that it is separated into individual squares.
