Answer:
16.7 m/s
Step-by-step explanation:
speed is always in units meters/seconds.
To get this unit, we need to convert the data into the right units.
30 km * 1000m = 30000 m
30 minutes * 60 seconds = 1800 seconds
30000 m / 1800 sec = 16.7 m/s
Answer:
+ 10 and + 7
Step-by-step explanation:
Given
2x² + 7x + 5
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 5 = + 10 and sum = + 7
Answer: 120 cartons
Step-by-step explanation: Since, the grocery clerk displays 15 cartons at the base of the triangle and one at the top. Therefore, one carton is reduced at previous step and so on. Since, this series is in arithmetic progression. Therefore, 120 cartons are needed for the complete display.
Answer:
y = -5/4x +1
Step-by-step explanation:
The slope-intercept form of a line is given by
y = mx + b where m is the slope and b is the y intercept
We are given the slope and a point on the line
y = -5/4 x + b
We can substitute the point for x and y and solve for b
-9 = -5/4(8)+b
-9 = -10+b
Add 10 to each side
-9+10=-10+10+b
1 = b
The slope intercept form of the equation is
y = -5/4x +1
Your answer will be 1 19/20
hope this helps
