Mr. Moore has 21 feet of wallpaper he cuts it into sections that are each 3 feet long how many
Total = 21 feet
if each is 3 feet
21/3 = 7
Therefore, there are 7 sections
Mathematics defines division as breaking into parts a larger unit to make several smaller units.
Division of 21 feet wallpaper into 3 feet section will give 7 small parts of the wallpaper.
To reach above answer, following calculation was made:
[tex]\begin{aligned} \rm Total\: length\:of \: the \:wallpaper &= 21\rm \:centimetres\\Length \:of\:each\:section &= 3\: \rm centimetres\end[/tex]
Therefore, number of sections will be the division of total length to length of each section.
[tex]\rm \begin{aligned} Number \:of \:sections &= \dfrac{\rmTotal\: length}{\rmLength\:of\:each\:section}\\ \\&= \dfrac{\rm 21\:centimetres}{\rm 3\:centimetres}\\\\&= \rm 7 \:sections \end[/tex]
Hence, 21 centimetres long wallpaper can be divided into 7 sections that are 3 centimetres long.

Need help evaluate the expression 5x - 7 for x =9? What is the answer?
An expression involving a variable is a way to express an idea, rather than a specific number. So, writing [tex] 5x-7 [/tex] means that there is a certain quantity, x, and you want to multiply it by 5, and then subtract 7.
Note that we don't want to know the value of x, we're only saying that we will multiply it by 5 and then subtract 7.
So, if we know that x=9, we will multiply it by 5 and then subtract 7:
[tex] 5x-7 = 5\cdot 9 - 7 = 45-7 = 38 [/tex]

Step-by-step explanation:
The davis family traveled 35 miles in 1/2 hour if it is currently 2:00pm any the family destination is 245 miles away at what time will they arrive explain
The distance traveled by Davis family = 35 miles
Time taken to cover the distance = [tex]\frac{1}{2}[/tex] hour
Speed = Distance [tex]\div[/tex] Time
Speed = [tex]35 \div \frac{1}{2}[/tex]
Speed = [tex]35 \times 2[/tex]
So, speed = 70 miles/hour.
At 2:00 pm, the family destination was 245 miles away.
So, the number of hours, when the family was 245 miles away = [tex]245 \div 70[/tex]
= 3.5 hours
So, after 3.5 hours, that is at 5:30 pm, the Davis family will be 245 miles away.
To find the Davis family's arrival time, you calculate the average speed, find the time needed for the remaining distance, and then add it to the current time of 2:00pm. Their arrival time is calculated to be 5:30pm.
The student asked: The Davis family traveled 35 miles in 1/2 hour. If it is currently 2:00pm and the family destination is 245 miles away, at what time will they arrive? To solve this, we need to calculate the total travel time based on their average speed and the remaining distance to the destination.
First, we find their speed by dividing the distance traveled by the time taken: 35 miles / 0.5 hours = 70 miles per hour. Next, we calculate the remaining distance to travel, which is 245 miles.
To find the time needed to cover the remaining distance, we divide the distance by the speed: 245 miles / 70 miles per hour = 3.5 hours.
Now, we add the travel time to the current time. Since it's 2:00pm, adding 3.5 hours gives us 5:30pm, which is the arrival time.

Answer:
19.57
Step-by-step explanation:
100% of 19 is 19.
In order to find out what 1% of 19, move the decimal point two place to the left. 1% of 19= 0.19. To find 3% of 19, multiply .19 x 3. add 0.19 x 3 to 19, aka add 0.57 to 19 to get 19.57= 103% of 19

Which of the numbers below correctly describes 63.45 Mhz? Select one: a. 0.06345 Ghz b. 63,450 khz c. Both a and b d. None of the above
To solve this question, let us take one part at a time.
Part 1 (MHz to GHz)
We know that 1 MHz=0.01 GHz
Therefore, [tex]63.45 MHz=63.45\times 0.001 GHz=0.06345 GHz[/tex]
Thus, for the time being we know that Option A is correct.
Part 2 (MHz to KHz)
We know that 1 MHz=1000 KHz
Therefore, [tex]63.45 MHz=63.45\times 1000 KHz=63450 KHz[/tex]
Thus, Option B too is correct.
Therefore, Both A and B are correct. Thus, out of the given options, Option C is correct.
A dairy needs 392 gallons of milk containing 5% butterfat. How many gallons each of milk containing 6% butterfat and milk containing 2% butterfat must be used to obtain the desired 392 gallons?
Qty % Qty * %
Solution 1: x 6% = 0.06 = 0.06x
Solution 2: 392 - x 2% = 0.02 = 0.02(392 - x) = 7.84 - 0.02x
Mixture: 392 5% = 0.05 = 0.06x + 7.84 - 0.02x
392(0.05) = 0.08x + 7.84
19.6 = 0.08x + 7.84
11.76 = 0.08x
147 = x
Solution 2: 392 - x = 392 - (147) = 245
Answer: 147 gallons 6% and 245 gallons of 2%
{x*0.02+0.06y=392*0.05
{x+y=392, x=392-y
0.04y=11.76, y=294; x=392-294=98
There is need 98 gallons of milk with 2% butterfat and 294 gallons of milk with 6% butterfat

What is m∠SVT?
Enter your answer in the box.
Answer:
m∠SVT= 79
Step-by-step explanation:
8y-33= 5y+9
Subtract 5y from both sides
8y-33= 5y+9
8y-33= 5y +9
-5y -5y
3y - 33= 9
Then add 33 to the other side
3y-33 = 9
+33 +33
= 3y= 42
Side by Side need to divide (divide by 3 on each side)
3y= 42
/3 /3
y= 143
m∠SVT = 5y + 9
m∠SVT = 5(14) + 9
m∠SVT = 70 + 9
m∠SVT = 79

Evaluate |-6| + 3|4| + |-5| - 0 × 6.
First of all, let's get rid of the absolute values. If the number inside is positive, don't do anything. If it's negative, switch the sign. So, the expression becomes
[tex] 6 + 3\cdot 4 + 5 - 0 \cdot 6 [/tex]
We have to perform multiplications first:
[tex] 6 + 12 + 5 - 0 [/tex]
The last subtraction by 0 doesn't affect the number in any way, so we can ignore it:
[tex] 6 + 12 + 5 [/tex]
Now you can perform the sums just as they appear:
[tex] 6 + 12 + 5 = 18 + 5 = 23 [/tex]
|-6| + 3|4| + |-5| - 0 * 6
Note: absolute value makes the number positive
6 + 3(4) + 5 - 0 * 6
Now, use the order of operations (multiply first)
6 + 12 + 5 - 0
Next, add and subtract
18 + 5 - 0
23 - 0

Answer: The 3,8,13,18 and 23 the actual common difference of this sequence.
Explanation:
The given terms of the sequence are 3,8,13,18 and 23.
Where first term is 3, second is 8, thirst term is 18, fourth term is 18 and fifth term is 23.
The difference between second and third term is 5.
[tex]8-3=5[/tex]
The difference between third and fourth term is 5.
[tex]13-8=5[/tex]
So, the common difference of the sequence is 5. Since the difference between terms are same, therefore it is an arithmetic progression.
The formula to find the nth term is ,
[tex]a_n=a+(n-1)d[/tex]
Where a is the first term and d is the common difference.

Just multiply (20 miles per week) by 1.40: 1.40(20 mpw) = 28 miles
Which numbers are 3 units from −6 on this number line?
Drag and drop all of the numbers that are 3 units from −6 to their correct position on the number line.
The numbers -9 and -3 are 3 units from −6 on this number line.
What is a number line?
In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.
In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.
A horizontal number line is the most common representation and can be extended infinitely in any direction.
Given a number line,
The 3 units left to the -6 is ⇒ -6 - 3 = -9
The 3 units right to the -6 ⇒ -6 + 3 = -3
Hence "The numbers -9 and -3 are 3 units from −6 on this number line".

The numbers that are 3 units from -6 on the number line are determined as: -9 and -3.
What is a number line?
A number line is a visual tool that displays numbers in a linear sequence, extending endlessly in both positive and negative directions, illustrating their comparative sizes and positions.
To find numbers that are 3 units from -6 on the number line, you need to consider both numbers that are 3 units to the right and 3 units to the left of -6.
To the right of -6: -6 + 3 = -3
To the left of -6: -6 - 3 = -9
So, the correct numbers are:
D. -3
B. -9
Place them on the number line accordingly.

Modeling and Solving a Problem:
An isosceles triangle has two sides of equal length. The third side is 5 less than twice the length of one of the other sides. If the perimeter of the triangle is 23 cm, what is the length of the third side?
Explain how you would define a variable for this problem.
The third side is 9 cm long
Let [tex]x[/tex] represent one of the equal sides. Then the` other side will be [tex]2x-5[/tex].
Adding all the length of the sides should give 23. Thus,
[tex]x+x+2x-5=23[/tex]
This implies that,
[tex]4x-5=23[/tex]
We group like terms and simplify to obtain.
[tex]4x=23+5[/tex]
[tex]4x=28[/tex]
Divide through by 4 to get
[tex]x=7[/tex]
Hence the length of the other side is
[tex]2(7)-5=9[/tex]
