Hey there! I'm happy to help!
We want to put this 0.002 into scientific notation, where you put it as a one digit number multiplied by 10 raised to a certain power.
If we move the decimal to the right 3 times, we will have 2. We will multiply this 2 by
to show that it is still equal to 0.002.
So, the mass of the mustard seed is 2×
.
Now, we multiply this mustard seed mass by the number of mustard seeds to find the weight of all of the mustard seeds combined.
(2×
)×(4.3602×
)
Let's round 4.3602 to the nearest whole number, which is 4. We multiply those two together.
2×4=8
And we multiply the two exponents. When multiplying them, you add the numbers in the exponent. -3 and 4 combined gives us 1, and 10 the first power is just 10.
So, a good estimate for the mass of the mustard seeds is 80 grams, which is the same as (2×
)×(4×
)=8×![10^1](https://tex.z-dn.net/?f=10%5E1)

Answer:
Step-by-step explanation:
By exterior angle theorem:
(9x - 8)° = (5x - 10)° + 50°
(9x - 8)° = (5x - 10 + 50)°
(9x - 8)° = (5x + 40)°
9x - 8 = 5x + 40
9x - 5x = 40 + 8
4x = 48
x = 48/4
x = 12
(9x - 8)° = (9*12 - 8)° = (108 - 8)° = 100°
