Answer:
To find this, you must find the total number of points Sara has scored already. She has answered 10 multiple choice questions which are 4 points each. This means that Sara has scored 40 points so far.
If Sara wants to score at least 70 points, she needs to score at least 30 more points. To find how many open-ended questions she needs to answer, you need to divide the remaining number of points by the number of points an open-ended question is worth. The number we get will be x.
30/5 = 6
This means Sara must complete at least 6 open-ended questions to score 70. Now, all we have to do is figure out which inequality sign to use. Since Sara wants to score more than 70 points, it should be the "greater than" sign.
Your answer is: x>6
Step-by-step explanation:
After you see the image you want to add 30 min which would make it 10:00 then you want to add 15 min. then you add your minutes together and get 45 min. And that would be your answer.
The answer is (4,8). I hope this helps.
Height of building =60 feet (where woman is trapped)
distance of bottom of ladder from base of building = 40 feet
This makes a right angled triangle as shown in figure.
here hypotenuse =length of ladder
base = distance of bottom of ladder from base of building = 40 feet
perpendicular =Height of building =60 feet (where woman is trapped)
So here we can use Pythagoras theorem to find the length of ladder.
Hypotenuse² = base² + perpendicular²
height of ladder = √(60² +(40)² = √3600 +1600 = √5200
height of ladder = 72.1 feet
