Answer:
-21 over 24 should be equivalent
Step-by-step explanation:
Equivalent fractions are simple. To find an equivalent fraction simply multiply the denominator AND the numerator by any natural number other than 1 (a natural number is any number greater than zero, numbers that ARE zero or less AREN'T natural numbers i.e. 0, -1, -2, -3, you get the point)
Answer:
2,674.14 g
Step-by-step explanation:
Recall that the formula for radioactive decay is
N = N₀ e^(-λt)
where,
N is the amount left at time t
N₀ is the initial amount when t=0, (given as 42,784 g)
λ = coefficient of radioactive decay
= 0.693 ÷ Half Life
= 0.693 ÷ 18
= 0.0385
t = time elapsed (given as 72 years)
e = exponential constant ( approx 2.7183)
If we substitute these into our equation:
N = N₀ e^(-λt)
= (42,787) (2.7183)^[(-0.0385)(72)]
= (42,787) (2.7183)^(-2.7726)
= (42,787) (0.0625)
= 2,674.14 g
#1 is 12x² -15x
#2 is fx-9x
Answer:
6
Step-by-step explanation:
|-6|
Apply rule |-a| = a
|-6| = 6
The distance between -6 and 0 is 6.
For Part A: the answer is 90 muffins total.
For Part B: the answer is 150 muffins total.
All you have to do is divide x (number of muffins the baker made) by 0.4 to get the total amount of muffins made.
