Answer:
C. 42.
Step-by-step explanation:
This is an arithmetic sequence with common difference d = 4 and first term a = -3.
Sum of n terms = (n/2)[2a + (n - 1)d]
Sum of six terms = (6/2)[2(-3) + (6 - 1)4]
= 3 * (-6 + 20)
= 42.
Answer:
The right expression is Option A - 3/4 divided by 5
Step-by-step explanation:
The whole cheese is 1.
Since she ate 1/4 of it, thus, she has,
1 - 1/4 = 3/4 left.
Now she split this remaining cheese into 5 places. Thus, it is expressed as;
(3/4) ÷ 5
This corresponds with option A
Ok sure I can find k
It is 21/16
1a.
you still have
k=C+273.15
k-C= 273.15 as related equations
b. at C=23
k=23+273.15 = 296.15
c. 25°C in kelvin = 25+273.15 = 298.15
so 300K is greater than 25°C
