Answer: $48
Step by step:
1. 30 packs times 64 dollars is 1920
2. 1920 divided by 40 packs is 48
because if you pay 64 for 40 packs and your trying to figure out how much for 30 packs you will want to set it up like this:
then you will use fishy method Google fish method in math if this doesn't help
Y-4=2(x-3)
Y-4=2x-6
Y+4= +4
Answer is Y=2x-2
Copy exactly how you see it
Answer:
X=-2 or x=-7
Step-by-step explanation:
(x+2)(x+7)=0
X=-2 or x=-7
Answer:
See Below.
Step-by-step explanation:
We want to use the Squeeze Theorem to show that:
Recall that according to the Squeeze Theorem, if:
And:
Then:
Recall that the value of sine is always ≥ -1 and ≤ 1. Hence:
We can multiply both sides by <em>x</em>². Since this value is always positive, we do not need to change the signs. Hence:
Let <em>g</em> = -<em>x</em>², <em>h</em> = <em>x</em>², and <em>f</em> = <em>x</em>²sin(2 / x). We can see that:
And since g(x) ≤ f(x) ≤ h(x), we can conclude using the Squeeze Theorem that:
If you have a calculator:
<span>1) To find 1%, divide by 100 (70 / 100 = 0.7) </span>
<span>2) Then, multiply by the % you need (0.7 x 13 = 9.1) </span>
<span>Therefore 70 - 9.1 = 60.9 </span>
<span>If you don't have a calculator: </span>
<span>1) Find 50%, 10%, 5%, and 1%. With these, you can make any % you need. </span>
<span>50% = X / 2 (= 35) </span>
<span>10% = X / 10 (= 7) </span>
<span>5% = first, do 10%, then divide that by 2 (= 3.5) </span>
<span>1% = X / 100 (= 0.7) </span>
<span>Where X is the number you want to work out % for </span>
<span>2) Add those % up to get the amount you want </span>
<span>10% + 1% + 1% +1% = 13% </span>
<span>7 + 0.7 + 0.7 + 0.7 = 9.1 </span>
<span>Therefore 70 - 9.1 = 60.9
Hope that helps :)</span>
