Assume all items are Lipgloss
Total Cost -> $7 x 9 = $63
difference-> $63-$50.50= $12.50
Assume that all were Lipgloss except for one item
Total Cost-> ($7x8)+$4.50= $60.50
diff-> $63-$60.50=$2.50
Number of Nail Polishes-> $12.50 diveded by $2.50 = 5
Number of Lipglosses-> 9-5=4
ANSWER:
Lipglosses:4
Nail Polishes :5
Answer:

Answer:
Step-by-step explanation:
When you have exponents above a like term and they are being multiplied together, you add them.
For example:
So let's group like terms in the numerator:
We can add terms like in the example.
Let's rearrange the denominator.
Now we have:
Cancel like terms
4/8 = 1/2
= 1 So it cancels
= s Since s is raised to the -1 it goes on top and becomes s.
Now we combine everything back together:
Answer:
Step-by-step explanation:
You can do long division, which is very very hard to show with typing on a keyboard. You essentially want to divide the leading coefficient for each term. Ill try my best to explain it.
Do . Write 2x^2 down. Now multiply (x - 3) by it. Then subtract it from the trinomial.
Now do . Write that down next to your 2x^2. Multiply 3x by (x - 3) to get:
Your final step is to do . Write this -2 next to your other two parts
Multiply -2 by (x - 3) to get:
Our remainder is 0 so that means (x - 3) goes into that trinomial exactly:
times
Answer:
785.0cm³
Step-by-step explanation:
Formula of calculating volume of a cylinder
= π r²h (Pie × radius square × height)
Radius given = 5cm
Height given = 10cm
working: π × radius²× height
= π × 5² × 10
=785.5398
=785.0cm³ (3s.f)
