The total cost of attending a state university is $19,700 for the first year. • A student's grandparents will pay half of this c
Temka [501]

Answer:

The student will have to save $404.2 minimum monthly

Step-by-step explanation:

Given that the total cost for the first year= $19,700

The grandparents paid half the amount = 1/2(19700)= $9850

The remaining balance to be paid is

19,700 - 9850=$9850

If an athlete paid $5000

The the remaining balance to be paid = 9850-5000=$4850

For the student to clear this amount in 12 months he must save

monthly 4850/12= $404.166

Hence the minimum amount to be saved per month is $404.2

Hello! can you please, help me by finding some missing angles.
yuradex [85]

Answer:

Going horizontally,

Q1 a) x = 133°

Q1 b) x = 59°

Q1 c) x = 189°

Q1 d) x = 32°

Q1 e) x = 72°

Q1 f) x = 36°

Q2 a) x = 53°

Q2 b) x = 94°

Q2 c) x = 10°

Workings out:

To work out the interior angles, you need to know that angles on a straight line add up to 180°. In addition, you also need to know that angles around a point add up to 360°. When you need to find a missing angle, if the angle is on a line or in a triangle, take whatever value/values the angle/angles you have are and take it away from 180°. If the angle is around a point, (or in a square, where all angles are the same anyway) add however many values you have for the angles then take that away from 360°. Hope this helps! :)
