Pls add your question
We know that
<span>The measure of the external angle is the semi difference of the arcs that it covers.
so
see the picture attached to better understand the problem
m AB=128</span>°--------> by central angle
<span>m ACB=360</span>°-128°-----> m ACB=232°<span>
</span>∠x=(1/2)*[m ACB-m AB]<span>
</span>∠x=(1/2)*[232-128]-----> ∠x=(1/2)*104°-----> ∠x=52°
<span>
the answer is</span>
∠ x is 52°<span>

Answer:
The will be 27000 bacteria in 36 hours from the start of the experiment
Step-by-step explanation:
In the first 18 hours:
The number of bacteria grew from 30 to 900.
So it grew by a factor of 900/30 = 30.
36 hours from the start of the experiment:
That is, the next 18 hours.
It will also grow by a factor of 30.
From 900 to 900*30 = 27000
The will be 27000 bacteria in 36 hours from the start of the experiment
Answer:
Step-by-step explanation:
To solve this you take 0 as the starting number, he lost 20 points so you subtract 20 and get -20. Next add 15 points. You then get -5. Then he got another answer right so you add 35 to -5. It the same if you say 35-5. Which gives you 30. So your answer is 30
Answer:
40x - 16
Step-by-step explanation:
(see attached for reference)
By utilizing the distributive property:
4(10x -4)
= (10x)(4) -4 (4)
= 40x - 16
