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
Answer:
1 pear = $0.75; 1 orange = $0.65
Step-by-step explanation:
(1) 3P + 4O = 4.85
(2) 3P + 10O = 8.75 Eqn (2) - Eqn (1)
3P + 10O – 3P – 4O = 8.75 – 4.85 Combine like terms
6O = 3.90 Divide each side by 6
O = $0.65 Substitute into Eqn (1)
3P + 4×0.65 = 4.85
3P + 2.60 = 4.85 Subtract 2.60 from each side
3P = 2.25 Divide each side by 3
P = $0.75
Oranges cost $0.65 each and pears are $0.75 each
The height of the fence is irrelevant. The bottom of the ladder is 3+8 = 11 feet from the building. The window is 14ft above the ground:
sqrt(14^2+11^2) = length of your ladder.
