The reason which is missing from the step 2 in the calculation of two similar triangle, is triangle angle sum theorem.

<h3>What is triangle angle sum theorem?</h3>

According to the triangle angle sum theorem, the sum of all the angle(interior) of a triangle is equal to the 180 degrees.

Given information-

The measure of the angle in the given problem is as,

m\angle H=30^o\\m\angle J=50^o\\m\angle P=50^o\\m\angle N=100^o

The two triangle has to be prove similar as,

\Delta HKJ \sim\Delta LNP

The image of the two triangle attached below.

The calculation done in the second step is as,

m\angle H +m\angle J+m\angle K=180

In the above calculation all the angle of the first triangle are added together. The result of the sum of all the angle of the triangle kept equal to the 180.

This is done by the property of triangle angle sum theorem, which says the sum of all the angle(interior) of a triangle is equal to the 180 degrees.

Thus the reason which is missing from the step 2 in the calculation of two similar triangle, is triangle angle sum theorem.

If N is the population of the colony and t is the time in​ days, express N as a function of t. Consider Upper N 0 is the origina
lesya [120]

Answer:

(a)N(t)=Noe^{kt}

(b)5,832 Mosquitoes

(c)5 days

Step-by-step explanation:

(a)Given an original amount N_o at t=0. The population of the colony with a growth rate k \neq 0, where k is a constant is given as:

N(t)=Noe^{kt}

(b)If N_o=1000 and the population after 1 day, N(1)=1800

Then, from our model:

N(1)=1800

1800=1000e^{k}\\$Divide both sides by 1000\\e^{k}=1.8\\$Take the natural logarithm of both sides\\k=ln(1.8)

Therefore, our model is:

N(t)=1000e^{t*ln(1.8)}\\N(t)=1000\cdot1.8^t

In 3 days time

N(3)=1000\cdot1.8^3=5832

The population of mosquitoes in 3 days time will be approximately 5832.

(c)If the population N(t)=20,000,we want to determine how many days it takes to attain that value.

From our model

N(t)=1000\cdot1.8^t\\20000=1000\cdot1.8^t\\$Divide both sides by 1000\\20=1.8^t\\$Convert to logarithm form\\Log_{1.8}20=t\\\frac{Log 20}{Log 1.8}=t\\ t=5.097\approx 5\; days

In approximately 5 days, the population of mosquitoes will be 20,000.

Help number 5. It would mean a lot.
brilliants [131]
Hi there!

This gets pretty easy once you understand how to do these kinds of problems. Let's look at the words in the question.

Adison earned 25$. We can push that to the side.
She loaned her friend 18$, which means she took some money away from her first part of it.

25 - 18 = 7$. Now she has 7$ left. (A calculator would be useful to answer these!)

Now, let's put the 7 to the side and check out the rest of the equation. Looks like Adison's grandmother gave her 50 more dollars, and we know that more means to add.

50 + 7 = 57$.

Now, the final part of the question says she ended up with 86$ because she had money before she earned more. To see how much money she had originally, we can subtract 86 from 57.

86 - 57 = 29$.

We now understand that Adison originally had 29$ before earning anymore money.

Hope this helps!

lara [203]
Janice bought 3 boxes.

Each box has 6 juice pockets. However, there are 15 players on the soccer team. Two boxes would not be enough, since that would only total 12 juice packets.

So, Janice has to buy 3 boxes, which is 18 juice packets.
