'what' means unknown or find this or ?
'is' means = or equals
22%
'of' means multiply
50
percent means parts out of 100
x%=x/100 so 22%=22/100
so
what is 22% of 50 means
?=22/100 times 50
?=1100/100
?=11
answer is 11
the hack, is to recognize that 50 is 1/2 of 100, so 22% of 1/2 of 100 is 22/2=11
answe ris 11
Answer:
<em>M(13)=14.3 gram</em>
Step-by-step explanation:
<u>Exponential Decay Function</u>
The exponential function is used to model natural decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:

Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The element has an initial mass of Mo=970 grams, the decaying rate is r=27.7% = 0.277 per minute.
The equation of the model is:


Operating:

After t=13 minutes the remaining mass is:

Calculating:
M(13)=14.3 gram
Answer:
A. E={
and
is a multiple of 8}
Step-by-step explanation:
Let
represent the set of natural numbers. Then we can write;
.
The set of all natural numbers that are multiples of 8 is then written as;
and
is a multiple of 8.
E is the set of natural numbers that are multiples of 8 can then be written in set builder notation as;
E={
and
is a multiple of 8}
The correct choice is A

Answer:
2/3
Step-by-step explanation:
Since the length increases by 0.5 cm every second, after 8 seconds the length will increase by 4 cm. 12 + 8 + 12 + 8 = 40, and 40 - (16 + 16) = 8. 8/2 = 4, so the width is now 4. 16 * 4 = 64, and 12 * 8 = 96. 64/96 = 2/3.
