Compute using long division: 342 ÷ 23
Answers
Start by setting it up with the divisor 23 on the left side and the dividend 342 on the right side like this:
2 3 ⟌ 3 4 2
Step 2:
The divisor (23) goes into the first digit of the dividend (3), 0 time(s). Therefore, put 0 on top:
0
2 3 ⟌ 3 4 2
Step 3:
Multiply the divisor by the result in the previous step (23 x 0 = 0) and write that answer below the dividend.
0
2 3 ⟌ 3 4 2
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (3 - 0 = 3) and write the answer below.
0
2 3 ⟌ 3 4 2
- 0
3
Step 5:
Move down the 2nd digit of the dividend (4) like this:
0
2 3 ⟌ 3 4 2
- 0
3 4
Step 6:
The divisor (23) goes into the bottom number (34), 1 time(s). Therefore, put 1 on top:
0 1
2 3 ⟌ 3 4 2
- 0
3 4
Step 7:
Multiply the divisor by the result in the previous step (23 x 1 = 23) and write that answer at the bottom:
0 1
2 3 ⟌ 3 4 2
- 0
3 4
2 3
Step 8:
Subtract the result in the previous step from the number written above it. (34 - 23 = 11) and write the answer at the bottom.
0 1
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1
Step 9:
Move down the last digit of the dividend (2) like this:
0 1
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1 2
Step 10:
The divisor (23) goes into the bottom number (112), 4 time(s). Therefore put 4 on top:
0 1 4
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1 2
Step 11:
Multiply the divisor by the result in the previous step (23 x 4 = 92) and write the answer at the bottom:
0 1 4
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1 2
9 2
Step 12:
Subtract the result in the previous step from the number written above it. (112 - 92 = 20) and write the answer at the bottom.
0 1 4
2 3 ⟌ 3 4 2
- 0
3 4
- 2 3
1 1 2
- 9 2
2 0
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 342 divided by 23 calculated using Long Division is:
14
The quotient after division is 322 and the remainder is 20.
What is long division?Long division is the mathematical method for dividing large numbers into smaller groups or parts.
Given that, 342 ÷ 23,
When we will divide 342 by 23, we will get,
The quotient 322 and the remainder is 20.

Answer:
Its perimeter is 23 units
Step-by-step explanation:
The perimeter of any figure is the sum of the lengths of its outline sides
The rule of the distance between two points is:
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]In the given figure ABCD:
Its perimeter = AB + BC + CD + DE + EA
→ Find the length of each side using the rule above
A = (-4, -2), B = (-1, 2), C = (2, 2), D = (5, -1), E = (2, -4)
→ Substitute them in the rule above to find the lengths of its sides
[tex]AB=\sqrt{(-1--4)^{2}+(2--2)^{2}}=\sqrt{(-1+4)^{2}+(2+2)^{2}}\\\\=\sqrt{(3)^{2}+(4)^{2}}=\sqrt{9+16}=\sqrt{25}[/tex]
∴ AB = 5
[tex]BC=\sqrt{(2--1)^{2}+(2-2)^{2}}=\sqrt{(2+1)^{2}+(0)^{2}}\\\\=\sqrt{(3)^{2}+0}=\sqrt{9+0}=\sqrt{9}[/tex]
∴ BC = 3
[tex]CD=\sqrt{(5-2)^{2}+(-1-2)^{2}}=\sqrt{(3)^{2}+(-3)^{2}}\\\\=\sqrt{9+9}=\sqrt{18}[/tex]
∴ CD = [tex]\sqrt{18}[/tex]
[tex]DE=\sqrt{(2-5)^{2}+(-4--1)^{2}}=\sqrt{(-3)^{2}+(-4+1)^{2}}\\\\=\sqrt{(-3)^{2}+(-3)^{2}}=\sqrt{9+9}=\sqrt{18}[/tex]
∴ DE = [tex]\sqrt{18}[/tex]
[tex]EA=\sqrt{(-4-2)^{2}+(-2--4)^{2}}=\sqrt{(-6)^{2}+(-2+4)^{2}}\\\\=\sqrt{(-6)^{2}+(2)^{2}}=\sqrt{36+4}=\sqrt{40}[/tex]
∴ EA = [tex]\sqrt{40}[/tex]
→ Add them to find the perimeter of the figure ABCDE
∴ Its perimeter = 5 + 3 + [tex]\sqrt{18}[/tex] + [tex]\sqrt{18}[/tex] +[tex]\sqrt{40}[/tex] ≅ 22.8098
→ Round it to the whole number

Flying agaist the wind, an airplane travels 6300 kilometers in7 hours. Flying with the wind, the same plane travels 8400 in 6 hours. What is the rate of the plane is still air and what is the rate of the wind?
Answers
Answer:
plane: 1150 kphwind: 250 kphStep-by-step explanation:
The given relationships allow us to write a system of equations in the speeds of the wind and plane.
Let w and p represent the speeds of the wind and the plane, respectively. We know speed is the ratio of distance to time, so ...
p -w = 6300 km/(7 h) = 900 km/h
p +w = 8400 km/(6 h) = 1400 km/h
__
Adding these two equations gives ...
2p = 2300 km/h
p = 1150 km/h . . . . . . divide by 2
Subtracting the first equation from the second gives ...
2w = 500 km/h
w = 250 km/h
The speed of the plane in still air is 1150 km per hour; the speed of the wind is 250 km per hour.

joanna has 45 postcards in her postcard collection, which is 180% of the number of postcards Kyle has. How many postcards does Kyle have?
Answers
Answer:
Kyle has 25 postcards
Step-by-step explanation:
Joanna has 45 postcards in her collection, which is 180% of the number of postcards of Kyle.
If the number of postcards of Kyle is K, and the number of postcards of Joanna is J, then:
J=180% K
Recall a percentage can be expressed in decimal by dividing by 100:
J=180/100*K
To find the value of K, we solve the above equation:
K=100/180*J
Since J=45:
K=100/180*45=25
Kyle has 25 postcards

12X + 16y = 96
12X + 48y = 192
Answers
Answer:
x=4
y=3
Step-by-step explanation:
12X + 16y = 96--(1)
12X + 48y = 192---(2)
(2)-(1),
12x + 48y - (12x+ 16y)= 192- 96
12x + 48y - 12x - 16y = 96
32y = 96
y= 96÷32
y =3
substituting y=3 in (1),
12x +(16×3) = 96
12x + 48 = 96
12x = 96-48
12x = 48
x= 48÷12
x= 4

so the vertex can be read from the given expression.
y > (x +2)^2 -1 ⇒ (h, k) = (-2, -1) . . . the vertex
The leading coefficient (+1) is positive so the parabola opens upward.

3x + 10
Answers
Answer:
x = 46
Step-by-step explanation:
Since the angles are equal to each other, make the equations equal to each other.
4x - 36 = 3x + 10 and simplify
x - 36 = 10
x = 46
Hope this helps!
The value of x is 46.
Since the angles are equal to each other, make the equations equal to each other.
4x - 36 = 3x + 10
First, let's move the term with 3x to the left side by subtracting 3x from both sides:
4x - 3x - 36 = 3x - 3x + 10
Simplifying further:
x - 36 = 10
Next, let's move the constant term -36 to the right side by adding 36 to both sides:
x - 36 + 36 = 10 + 36
Simplifying further:
x = 46
Therefore, the value of x is 46.
