Answer:
scale drawing you should use a limited unit of measurement so you are not drawing actual scale of the kitchen use 1 to40
Answer:
2 dollars for kids
5 dollars for adults
Step-by-step explanation:
We will let x= children
y= adult
we know that
33x+42y=276
46x+40y=292
There are a lot of ways you can solve this but I think it's easiest if we use (what I think is called elimination)
we will start by mulitiplying the second equation by 1.05 to get
48.3x+42y= 306.6
We will subtract the first equation from the second to get
15.3x= 30.6
Solve for x and get 2
Now that we know what x equals we can plug that into any equation and solve for y
we have
33(2)+42y=276
y=5
This shows that about 7 and 3 pounds of each chocolate were included in the mixture.
Let the number of pounds of both chocolates be x and y.
If Enrico sold a 10-pound box of assorted chocolates, hence;
x + y = 10 ................. 1
If some of the chocolates in the box sold for $1.75 per pound and some sold for $2.00 per pound with mixture sold for $1.90 per pound, then:
1.75x + 2x = 1.90 ................ 2
Solve equations 1 and 2 simultaneously.
x + y = 10 ................. 1 * 20
17.5x + 20x = 19 ................ 2 * 1
____________________________
20x + 20y = 200
17.5x + 20x = 19
Subtract
20x - 17.5x = 200 - 19
2.5x = 181x = 7.24
Substitute 7.24 into 1
x + y = 10
y = 10 - 7.24
x = 2.76
This shows that about 7 and 3 pounds of each chocolate were included in the mixture.

The difference of two squares expression is (d) 25a^2-36b^6
<h3>How to determine the difference of two squares?</h3>
The difference of two squares is represented as:
x^2 - y^2
Where x and y are perfect square expressions.
From the list of options, we have:
25a^2-36b^6
The terms of the above expression are perfect squares
i.e.
25a^2 = (5a)^2
36b^6 = (6b^3)^2
Hence, the difference of two squares expression is (d) 25a^2-36b^6
