Answer:
Q1:
150 pages is the answer
2 hours= 60+60minutes
So 120/40 =3
Answer= 50×3= 150.
Q2:
Using Work=men×days we get
Work=20×20
Work=400
Now, work is same and number of days are to be calculated
400=25×days
days= 16
400 = 25 x 16
so it will take 16 days

Answer:
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex ad a is a multiplier
Here (h, k ) = (8, - 1 ) , then
y = a(x - 8)² - 1
To find a substitute (0, - 17 ) into the equation
- 17 = a(0 - 8)² - 1 ( add 1 to both sides )
- 16 = 64a ( divide both sides by 64 )
= a , that is
a = -
y = - (x - 8)² - 1 ← equation of parabola
The thousands place value is the fourth digit (number) to the left of the decimal point. If the decimal point is not present, it goes to the right of the digit at the end of the number. So 4 over from that is the starting number, 4. So there are 4 thousands in the thousands place
Answer:
It travels for 3 hours, then stops, for 1 hour, and finally travels again for 1 hour
Step-by-step explanation:
for the first 3 hours (x terms in coordinates, 0 to 3) the car is gaining miles (the y terms in the coordinates given, 0 to 42), then from hour 3 to hour 4 (1 total hour) no miles are gained (y terms 42 to 42=no change/no gain), and the the miles change again from hour 4 to hour 5 (x terms again, 4 to 5), 1 total hour
