Answer:
C) 10,000,000
Step-by-step explanation:
Data provided in the question:
- The phone number is of 7 digits
- we have choices from 0-9
meaning 10 number of choices, 0 1 2 3 4 5 6 7 8 9
we have 10 choices out of 10 for each of the 7 blanks
Therefore,
The total number of different phone numbers can there be in one area code that can be formed
= 10 × 10 × 10 × 10 × 10 × 10 × 10
= 10^7
= 10,000,000
Times the price of the model cars to the amount bought.
$15×6= 90.
Lea paid 90 dollars for the model cars.
Now, multiply the price of the paint to the amount bought.
$11×4= 44.
Lea paid 44 dollars for the paint.
Add both together. 90+44= 134.
Therefore, Lea paid $134 for the model cars and paint all together.
hope this helps!
It’s empty xD “what is the vent diagram of an empty set like?” Just kidding I don’t know the Awnser btw..
X= -22.25. You subtract the 4.5 so the x can by it self
Here, let the age of student be x and teacher be 4x after 28 years, the teacher is double the age of student. So the age of teacher will be 4x+28 and student will be 2(x+28)
So,
4x+28=2(x+28)
4x+28=2x+56
4x-2x=56-28
2x=28
x=14
Therefore the age of the teacher in present will be
=4x+28
=4*14+28
=84
And age of student will be:
=x+28
=14+28
=42
Hope this helps
