Answer:
The call lasted 13 minutes
Step-by-step explanation:
In this question, we are told to find the number of minutes a call lasted.
The initial amount on the card is $30 and after making a phone call just once, the balance went down to $28.83
What was used would be 30 - 28.83 = $1.17 or simply 117 cents
Now these long calls come at a cost of 9 cents per minute and we have a total of 117 cents here; the number of minutes is thus 117/9 = 13
This means Kala spent 13 minutes on the call
Answer:
Step-by-step explanation:
1. take out constants
( 5 × 2 × 4 × - 4 × - 2) 
2. simplify 5 × 2 to 10
(10 × 4 - 4 × - 2)
3. simplify 10 × 4 to 40
(40 × - 4 × - 2)
4. simplify 40 × -4 to -160
(-160 × - 2)
5. simplify -160 × -2 to 320
6. use product rule:
7. simplify 5 + 5 to 10
8. simplify 10 + 5 to 15
Answer:
2. 
3. 
- definition of perpendicular
4. 
- all right angles are congruent
6. 
7. 
Step-by-step explanation:
<u>Given: </u>Point P is the perpendicular bisector of AB
<u>Prove: </u>P is equidistant from the endpoints AB
<u>Proof.</u>
1. Point P is on the perpendicular bisector of AB - given
2. - definition of bisector
3. - definition of perpendicular
4. - all right angles are congruent
5. 
- reflexive property of congruence
6. - SAS congruency postulate
7. - corresponding parts of congruent triangles are congruent
8. Point P is equidistant from the endpoints of AB - definition of equidistant
You need to multiply 18*3 to get the number of balls needed. Then you have to divide the answer with 8 to get the amount of boxes needed.
18x3= 24
24x8= this will give you your answer
