90° angle
90° - existing 42°
the missing angle is 48°
Answer:
$3.88
Step-by-step explanation:
You want to leave a 18% tip on a meal that cost $21.58.
First, convert the 18% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 18%) by 100%.So, the conversational term "18%" becomes 18% / 100% = 0.18 in terms of a real mathematical number.
Second, you need to find out what 18% of your $21.58 meal cost is.This is always done by multiplying 0.18 by $21.58, or 0.18 x $21.58=$3.88.
So, the amount of tip you are going to leave is $3.88.
A factorial of 7 numbers is just multiplying 7 numbers together like this 1*2*3*4*5*6*7, which equals 5040.
If you wanted to get fancy, you could reword the questions and say, "what is the factorial of 5040?" In that case the answer is 1*2*3*4*5*6*7
15kg=33 lbs
48.4 lbs/2.2 lbs. =22 kg
1 kg = 2.2 lbs so when you need to make a conversion wityh kilograms and pounds write that out then put how ever many pound you need to get to under the 2.2 lbs and cross multiply same with the kilograms.
<u>Answer</u>:
Option 5: -4 ≤ 7x - 7 ≤ 4
<u>Step-by-step explanation:</u>
It is required to find which expression is equivalent to |7x-7| ≤ 4
So, at the beginning we should review the rules of absolute value inequalities.
1) If |x| ≤ a ⇒ -a ≤ x ≤ a
2) If |x| < a ⇒ -a < x < a
3) If |x| ≥ a ⇒ x ≤ -a or x ≥ a
4) If |x| > a ⇒ x < -a or x > a
Applying the first rule to the given absolute value inequality:
|7x-7| ≤ 4 ⇒ -4 ≤ 7x-7 ≤ 4
So, the answer is option 5
