Answer:
8 pieces of wood should be put along each side of the chessboard
Step-by-step explanation:
Here in this question, we are interested in knowing the the number of pieces of wood that should be put along each side of the cheese board.
Firstly, to know the number of pieces of wood to use, we need to divide the area of the board by the area of each piece of wood
Mathematically that would be 64 square inches/ 1 square inch = 64 pieces of wood
64 pieces of wood would be needed to complete the cheeseboard.
The number of pieces to put along each side of the cheese board will be √64.
This is because the shape of a chessboard is square.
Thus the number of pieces to put on each side will be √64 = 8

How are the expressions 8 - 15 and 8 +(15) alike? How are they different?
Well, one thing they ahve in common is that they are both adding or subtracting the same numbers and of course, they are both expressions.
They are different because one expression is subtract both numbers while one expression is adding both numbers.
8 - 15 = -7
8 + 15 = 23

Before comparing mixed fractions, let's make them inappropriate
2 1/2 = 5/2
3 1/3 = 10/3
Comparing fractions. (MMC - Maximum Common Multiple - I don't know that term in English)
2 1/2 = 5/2 = 15/6
3 1/3 = 10/3 = 30/6
30/6 > 15/6 then
3 1/3 > 2 1/2A group of 24 students have recess together. They are making teams to play a game. Each team has to have exactly 5 players, and no one can be than one team. How many teams can they make? ( it is possible that not everyone can be on a team.)
solve the equation for x
Answer
x = 15Step-by-step explanation:
[tex] \sf{ \frac{40}{x + 1} = \frac{15}{6} }[/tex]
Do cross multiplication
[tex] \dashrightarrow{ \sf{15(x + 1) = 40 \times 6}}[/tex]
Distribute 15 through the parentheses
[tex] \dashrightarrow \sf \: 15x + 15 = 40 \times 6[/tex]
Multiply the numbers : 40 and 6
[tex] \dashrightarrow{ \sf{15x + 15 = 240}}[/tex]
Move 15 to right hand side and change it's sign
[tex] \dashrightarrow{ \sf{15x = 240 - 15}}[/tex]
Subtract 15 from 240
[tex] \dashrightarrow \: \sf{15x = 225}[/tex]
Divide both sides by 15
[tex] \dashrightarrow{ \sf{ \frac{15x}{15} = \frac{225}{15} }}[/tex]
Calculate
[tex] \dashrightarrow{ \sf{x = 15}}[/tex]
Hope I helped!

A new Youth Activity Center is being built in Hadleyville. The perimeter of the rectangular playing field is 430 yards. The length of the field is 5 yards less than quadruple the width. What are the dimensions of the
playing field?
The width is yards.
The length is yards.
Answer:
Width = 44 yards
Length = 171 yards
Step-by-step explanation:
Given:
Perimeter of the rectangular field = 430 yards.
Let:
The length of the field be L
The width of the field be W.
From the question:
The length of the field is 5yards less than quadruple the width. This implies that;
L = 4W - 5
But.
Perimeter (P) of a rectangle is given by:
P = 2(L + W) ---------------(i)
Substitute the values of P = 430, L = 4W - 5 and W into equation (i) as follows;
430 = 2(4W - 5 + W)
430 = 2(5W - 5)
430 = 10W - 10
10W = 430 + 10
10W = 440
Divide both sides by 10
W = 44
Therefore, the width of the field is 44 yards.
Remember that,
L = 4W - 5
[Now substitute W = 44]
L = 4(44) - 5
L = 176 - 5
L = 171
Therefore, the length of the field is 171 yards
0.00035
Write each number in scientific notation.
Step-by-step explanation:
For example, in order to multiply 832,000 by 0.00035, one converts first to scientific notation as follows: (832,000)×(0.00035)=(8.32×10 5)×(3.5×10 −4)=8.32×3.5×10 5×10 −4=29.12×10 1=2.912×10 2 (in scientific notation) or 291.2 (in ordinary notation).
Answer:
0.00035 = 3.5 × 10 to the -4

Answer:
[tex]Wood\ remain = 1\frac{3}{4}[/tex]
Step-by-step explanation:
Note; given question is incomplete
Size of pieces = [tex]1\frac{2}{3} ,2\frac{3}{4} , 3\frac{5}{6}[/tex]

[tex]Wood\ remain = 10-\frac{5}{3} -\frac{11}{4} - \frac{23}{6}\\\\Wood\ remain = 10 - \frac{99}{12} \\\\Wood\ remain = 1\frac{3}{4}[/tex]
Question is given in picture below. Help will be greatly appreciated!
Answer:
C
Step-by-step explanation:
Th explicit formula of a geometric sequence has the following format:
[tex]x_n=a(r)^{n-1}[/tex]
Where a is the initial term and r is the common ratio.
From the recursive formula, we can see that each subsequent term is multiplied by 13. Thus, the common ratio is 13.
Also, we are given that the first term is 7.
So, substituting these in, we have:
[tex]x_n=7(13)^{n-1}[/tex]
Our answer is C
And we're done!

what sequence of transformations on the red triangle will map it onto the missing portion of the square
Answer:
Answer is C.) a 90° counterclockwise rotation about the origin and then a translation 16 units right and 16 units up
Step-by-step explanation:
Rotating the triangle 90° counterclockwise will take the triangle to 3rd quadrant and then further moving it 16 steps right will take it to 4th quadrant and followed by 16 steps upward will take it to the desired position which is in 1st quadrant.
Factorise :
[tex] \sf{ {x}^{2} - 4x - 21 + 10y - {y}^{2} }[/tex]
Show workings too!
Answer:
(x - y + 3)(x + y - 7)
Step-by-step explanation:
x^2 - 4x - 21 + 10y - y^2
= x^2 - y^2 - 4x -21 + 10y
= (x - y)(x + y) - 4x + 10y - 21 Now -21 = + 3 * -7 and +3x - 7x =- 4x so we try:
= (x - y + 3)(x + y - 7)
- this expands to the original expression.
Answer:
(x+y-7)(x-y+3) is your answer
Step-by-step explanation:
x²-4x-21+10y-y²
x²-4x+2²-2²-21+10y-y²
(x-2)²-(y2-10y+25)
(x-2)²-(y-5)²
(x-2+y-5)+x-2-y+5)
(x+y-7)(x-y+3)
x + 9 = 18 + -2x what does x epual
Answer:
x = 3
Step-by-step explanation:
Step 1: Write out equation
x + 9 = 18 - 2x
Step 2: Add 2x on both sides
x + 2x + 9 = 18 - 2x + 2x
3x + 9 = 18
Step 3: Subtract 9 on both sides
3x + 9 - 9 = 18 - 9
3x = 9
Step 4: Divide both sides by 3
3x/3 = 9/3
x = 3

Q8
The midpoint of GH is M (2,2). One endpoint is H (1,9). Find the coordinates of endpoint G.
Answer:
(3,-5)
Step-by-step explanation:
Given
[tex]M = (2,2)[/tex]
[tex]H = (1,9)[/tex]
Required
Determine G
This is calculated using the following midpoint formula;
[tex]M(x,y) = (\frac{x_1 + x_2}{2},\frac{y_1 + y_2}{2})[/tex]
Where
[tex](x,y) = (2,2)[/tex] and [tex](x_1,y_1) = (1,9)[/tex]
Substitute these values in the formula above
[tex](2,2) = (\frac{1 + x_2}{2},\frac{9 + y_2}{2})[/tex]
Solving for [tex]x_2[/tex]
[tex]2 =\frac{1 + x_2}{2}[/tex]
Multiply both sides by 2
[tex]2 * 2 = 1 + x_2[/tex]
[tex]4 = 1 + x_2[/tex]
[tex]x_2 = 4 - 1[/tex]
[tex]x_2 = 3[/tex]
Solving for [tex]y_2[/tex]
[tex]2 = \frac{9 + y_2}{2}[/tex]
Multiply both sides by 2
[tex]2 * 2 = 9 + y_2[/tex]
[tex]4 = 9 + y_2[/tex]
[tex]y_2 = 4 - 9[/tex]
[tex]y_2= -5[/tex]
Hence, the coordinates of G is [tex](3,-5)[/tex]
Min-jun has a swimming pool that needs to be drained. His pool holds
10,874.5 gallons of water and will need to drain completely in 10.7
hours. What is the change in the water level per hour for Min-jun's
swimming pool? Round your answer to the nearest hundredth.
Answer:
The change in the water level per hour for Min-Jun's swimming pool is 1016.31 Gallons per hour.
Step-by-step explanation:
Since we have a total amount of 10,874.5 gallons and 10.7 hours total to drain the full pool we divide the total amount by the total time, assuming that the pool drains at a constant rate. When we divide 10,874.5 by 10.7 we get 10.16.3084... and rounding it to the nearest hundreth or the second decimal place we get 1,016.31 gallons per hour.

Does it make sense to represent the number 15.3 using scientific notation yes or no?
Answer:
Not really. No.
Step-by-step explanation:
15.3 in scientific notation would be represented as "1.53e+1." 15.3 isn't a very large or tiny number. Usually numbers that would be represented by scientific notation would be numbers such as "600,000,000" or "0.00000012" etc. 15.3 is just a standard decimal so it's not really practical.
Hope this helps and have a nice day!
