Answer:
The last graph best represents the story
Step-by-step explanation:
Mary left for school from rest. So the initial speed is zero.
So we start from the origin and draw a straight line with a positive slope to running, that is as time increases , distance covered also increases.
When she is resting, her speed is zero so we draw a horizontal line to indicate this second phase of her journey.
After resting she still continued her journey to school.
This part also has a positive slope.
12+6x was subtracted from the left but only 12 was subtracted from the right.
6x and 6 are not equal unless x=1
X=-11/15
9t = 27.99
5t = ?
Cross-multiply : 9t? = 139.95t
?=15.55
Answer:
Length , time, mass, current, temperature, amount of mass, luminous intesity
m, sec, kg, A, K, mol, cd
Step-by-step explanation:
Seven basic SI units are used for measurement of
Meter for length
Second for time
Kilogram for mass
Ampere for current
Kelvin for temperature
Mole for amount of mass
Candela for luminous intensity
Symbols of these SI units are
m for meter
sec for second
kg for kilogram
A for ampere
K for kelvin
mol for mole
cd for candela
True is the correct answer Hope this helped =)
