Answer:
Step-by-step explanation:
We have been given a graph of similar triangles. We are asked to find the value of x.
Since we know that corresponding sides of similar triangles are always in same proportion, so we will use proportions to find the length of x.
Upon cross multiplying our equation we will get,
Upon distributing 4 we will get,
Let us subtract 12 from both sides of our equation.
Upon dividing both sides of our equation by 4 we will get,
Therefore, the value of x will be 12.
Answer:
1. $35.075
2. 43.5 hours
3. 70%
4. Danny is correct
5. Abe's score out of the 30 points of the last quiz to get an overall checkup quiz grade of 80% should be 28.5
Step-by-step explanation:
The pay per hour for student tutors = $5.75
1. A tutor who worked 3.4 hours on Monday and 2.7 hours on Thursday has worked, 3.4 + 2.7 = 6.1 hours for the week, therefore
The week earning for the tutor = 6.1 × 5.75 = $35.075
2. The Club's tutoring budget per week = $250
The number of tutoring hours that can be provided per week is given by the relation;
3. The score of 21 out of 30 as a percentage is given as follows;
4. Where the second score is 45 out of a total of 60 points, we have;
Therefore, the increase in Abe's score is 5%, therefore, Danny is correct
5. To raise his checkup quiz grade to 80% overall, then we should have;
Where:
Q = The percentage grade of the last quiz
(145 + Q)×100 = 80×300 = 24000
145 + Q = 240
Q = 240 - 145 = 95%
Therefore, he has to score, 95% of 30 on the last quiz, which is thus;
Abe's score out of the 30 points of the last quiz to get an overall checkup quiz grade of 80% = 28.5 points.
