sukhleen is making a chess board she has 210cm2 of wood with which to make the white squares 210cm2 of wood with which to make the black squares and 6500mm2 of word to make a border
what is the total area of the chessboard?
Answer: 1070cm2
Step-by-step explanation: Hi there
(Not taking the number of squares into account)
1. Convert 6500 millimeters to centimeters
6500mm=650cm
2. Add the area of the wood
650+210+210=1070
So the total area is 1070 cm2

Tomas learned that the product of the polynomials [tex](a+b)(a^2-ab+b^2)[/tex] was a special pattern that would result in a sum of cubes, [tex]a^3+b^3[/tex].
His teacher put four products on the board and asked the class to identify which product would result in a sum of cubes if [tex]a=2x[/tex] and [tex]b=y[/tex].
We are provided , Tomas learned that a³ + b³ = (a + b ) ( a² - ab + b² ) , and his teacher writes four products on the board and we have to tell that which product suits the best if a = 2x and b = y
Now , putting a = 2x , b = y in the given formula we have :
[tex]{:\implies \quad \sf (2x)^{3}+(y)^{3}=(2x+y)\{(2x)^{2}-2\cdot x\cdot y+(y)^{2}\}}[/tex]
[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{(2x)^{3}+(y)^{3}=(2x+y)(4x^{2}-2xy+y^{2})}}}[/tex]
Hence , The product (2x+y) (4x²-2xy+y²) would result in the sum of cubes of 2x & y :D
if you do this for me I'll love you forever!!!!
Answer:
1: B
2: H
3. C or D (it's hard to tell, especially without an equation)
4. J
5. A
6. G
7. B
Step-by-step explanation:
1:
f(x) - g(x)
(x^2 + 8x) - (3x - 5) Distribute the negative
x^2 + 8x - 3x + 5 Combine like terms
x^2 + 5x + 5
2:
f(g(x))
Plug g(x) into f(x)
(2x - 1)^2 - 3
Immediately we can see that there will be a 4x^2 (because 2x times 2x = 4x^2) so we know the answer will be H because that's the only option with 4x^2
3:
The line starts at -4 on the x axis and goes infinitely to the right so everything greater than (and maybe equal to) -4.
On the y axis, the line starts at 0 and goes infinitely up so everything greater than (and maybe equal to) 0.
4:
To find the inverse of a function:
f(x) -> y
Switch x and y
Solve for y again
x = 3 +5y
x-3 = 5y
(x-3)/5 = y
5:
If option A were inverse functions, h(x) would be
x = 2y + 9
x - 9 = 2y
(x-9)/2 = y
Which could also be written as (1/2)x - 9/2 or (1/2)x - 4.5 but not (1/2)x - 9
6:
As y approaches -1, x approaches 1. Going the other direction,
As y approaches positive infinity, x approaches positive infinity.
7:
The number inside directly affecting the x moves the function left and right (left is positive, right is negative). The number outside moves the function up and down. So (x + 4) moves it left 4 and the +1 moves it up 1.

Find the measure of the indicated angle in each triangle
47
86
180
133
Answer:
47°
Step-by-step explanation:
86°+47°+F=180° (reason : sum of angles in a triangle)
133°+F=180°
Collect like terms
F=180°-133°
F=47°
An electrician has 350 clients. If the electrician can see 5 clients per day; how many days will it take for him to see 30% of his clients
Answer:
21 days
Step-by-step explanation:
Start off by finding out what 30% of 350 is. Which is 105. Then divide 105 by 5 which gives you 21.

5x - 7 < 13
Answer:
5x-7 has to equal to something smaller than 13
5x-7=5
Answer: x < 4
Step-by-step explanation:
Disregarding the lesser than sign, we can treat this equation as 5x-7=13. This doesn't work all the time as there are rules, but those rules don't apply to a simple inequality such as this.
5x-7<13
5x<20
x<4
And so, our answer is x<4

If John takes 2 hours to travel 20km,how many kilometers does he travel in 6 hours?
Answer:
60km
Step-by-step explanation:
There are two ways to look at this
1. Finding the unit rate
We can find how many km he travels in 1 hour by diving both the hours and km by 2. 1 hour = 10km so 6 hours is 60km since we multiply by 6.
2. Multiply by 3
We can multiply both the km and hours by 3, since 2x3=6 hours
20km * 3 hours = 60km

Maria is building a circular pool. The radius of the pool will be 7 feet. She will put a cover on the pool and build a fence around the pool. How much material will she need to cover the top of the pool?
Answer:
about 154 square feet
Step-by-step explanation:
The area of the pool is given by the formula for the area of a circle:
A = πr²
A = π(7 ft)² = 49π ft² ≈ 153.94 ft²
About 154 square feet of material will be needed to cover the top of the pool.

Additional comment
The circumference of the pool is 2πr, or 14π feet -- about 44 feet.
How can you use estimation to find
92 +91 +92 +91 +9?
Answer:
370
Step-by-step explanation:
Round each answer into easier to add numbers. 92 and 91 round down to 90. 9 rounds up to 10.
Answer:
aprox 280
Step-by-step explanation:
if you need to add these numbers quickly you can estimate either with an overestimation or under estimation:
for an over estimation, you can find the nearest 10 or 100 that each value is so for this you have 92 + 91 +92 +9 which is close to 100 +100+100+10
so using this you can quickly guess that it would be somewhere around 310
for an under estimation you can do the same thing but rounding down so we instead would add 90 + 90 + 90 + 10 which gives 280
now using both we know the answer would be somewhere between 280 and 310

Find the co-interior angle measurements for the measured angle.
Thanks! :)
Answer:
71°
Step-by-step explanation:
Line AB is parallel to line CD and that makes the angle given as 109 and the co-interior angle supplementary
since the sum of supplementary angles is equal to 180° :
180 - 109 = 71 is the measure of the co-interior angle

Sophia is designing the seating arrangement for a concert and
outdoor theater. To give everyone a good view, each row must have 8
more seats than the row before it, and the 1st row can only have 13
seats. Help Sophia plan the rest of the seating by solving for how many seats are in row 20. Then explain to Sophia how to create an equation to predict the number of seats in any row.
Answer:
the answer for the first part is 260
the equation is n+8
Step-by-step explanation:
all you need to do is take the starting number witch is 13 then you add 8 and then take that number and add 8 so thats why the equation is n+8 n equaling the starting number and 8 equaling to the reoccurring number.
I have 12 more nickels than quarters. It the coins are worth $5.40, then how many of each type
of coin do I have?
Answer:
You have 16 quarts and 28 nickels lol
Step-by-step explanation:
Answer:
16 quarters and 28 nickels
Step-by-step explanation:
Because...
1 quarter=25 cents of so if you have 16 quarters that=4.00$
2 if there are 12 more nickels then there are 28 nickels.
1 nickle=5 cents. so what is 28 x 5=1.40$
Then add 4.00$+1.40$=5.40$ and there is your answer.
