find the missing angle of the triangle 42° 87° x
​

Answer:

1115322

Step-by-step explanation:

In 1906, San Francisco felt the impact of an earthquake with a magnitude of 7.8.

Claimed statement is he worst is yet to come, with an earthquake 142,990 times  as intense as the 1906 earthquake ready to hit San Francisco.

We need to find the magnitude of their  claimed earthquake.

It can be calculated by simply multiplying 142,990 by 7.8 as follows :

[tex]E=142990 \times 7.8\\\\=1115322[/tex]

The magnitude of claimed earthquake is 1115322 .

Using the earthquake intensity relation on the Ritcher scale, the magnitude of the claimed earthquake would be 13.0

Uisng the relation :

Substituting the values into the equation :

[tex] M_{a} - 7.8 = log(142990) [/tex]

[tex] M_{a} - 7.8 = 5.1553056 [/tex]

[tex] M_{a}= 5.1553056 + 7.8 [/tex]

[tex] M_{a} = 12.955 [/tex]

Therefore, the magnitude of the claimed earthquake would be 13.0

Answer:

$359.13

Step-by-step explanation:

To find the total cost of her room we have to add the cost of the tax to the cost of the room.

To find the value of the tax, multiply the value of the room(325) by 10.5%:

Convert 10.5% to decimal form: 0.105

0.105 * 325 = 34.125

34.125 rounds up to 34.13.

Now, add the cost of the tax to the room's cost:

34.13 + 325 = 359.13

The total cost of the hotel room is $359.13.

The cost of a hotel room during Lacy’s trip is $325 and the hotel room tax in the city she is in is 10.5%, so the total cost of the hotel room will be $ 359.13.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

It is given that the cost of a hotel room during Lacy’s trip is $325. The hotel room tax in the city she is in is 10.5%.

The total cost of the hotel room is,

Total cost = hotel room tax + cost  of a hotel room

Total cost = 10.5% of $325 + $325

Total cost = $ 34.12 + $325

Total cost =  $ 359.13

Thus, the cost of a hotel room during Lacy’s trip is $325, and the hotel room tax in the city she is in is 10.5%, so the total cost of the hotel room will be $ 359.13.

Given:

The given equation is

[tex]60=5(1.07)^x[/tex]

To find:

The initial value and growth/decay factor.

Solution:

The general exponential growth/decay model is

[tex]y=a(1+r)^x[/tex]     ...(i)

where, a is initial value, if r>0, then |r| is growth factor, if r<0, then |r| is decay factor and x is time.

We have,

[tex]60=5(1.07)^x[/tex]

It can be written as

[tex]60=5(1+0.07)^x[/tex]        ...(ii)

On comparing (i) and (ii), we get

[tex]a=5\text{ and }r=0.07[/tex]

Here, initial value is 5 and growth factor is 0.07, i.e., 7%.

Therefore, the correct option for first question is d and correct option for second question is a.

a₇ = 192

Step-by-step explanation:

There is a common ratio r between consecutive terms in the sequence.

r = 6 ÷ 3 = 12 ÷ 6 = 2

This indicates the sequence is geometric with n th term

[tex]a_{n}[/tex] = a₁ [tex]r^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 3 and r = 2 , thus

a₇ = 3 × [tex]2^{6}[/tex] = 3 × 64 = 192

the equation 2x-4-1+x would be the answer

Because 2x+x = 3x and -4-1 = 5, the result would be 3x-5

C = 306 +1.3x

Step-by-step explanation:

In 1950 the average atmospheric concentration of carbon dioxide was 306 parts per million with an estimated increase of 1.3 parts per million every single year. Therefore we can use these numbers to create the following mathematical model.

C = 306 +1.3x

This model multiplies the number of years after 1950 (x) by the estimated carbon dioxide increase per year in parts per million, and finally adds the initial atmospheric concentration of carbon dioxide from 1950 to calculate the current atmospheric concentration of carbon dioxide

Answer:

The general form of an exponential function is

             .... (1)

Where, a is initial value and b is growth or decay factor.

If b>1, then it is an increasing function and if 0<b<1, then it is a decreasing function.

The given function is

          .... (2)

From (1) and (2) it is clear that

The value of a is 6. It means the initial value or y-intercept of the function is 6.

The value of b is 0.4, which is less than 1. It means the function is a decreasing function.

Let x be the following values: 1, 2, 3, 4 , 5.

Let f(x) = y.

I will do one only.

Let x = 1

y = 6•(0.4)^(1)

y = 6•(0.4)

y = 2.4

Your first point is (1, 2.4).

Do the rest in like manner. Then graph each point on the xy-plane and lastly connect each point with a smooth curve.

Answer:

Step-by-step explanation:

∠1+∠2=180°

3x+x+36=180

4x=180-36=144

x=144/4=36°

∠1=3x=3×36=108°

∠2=x+36=36+36=72°

The measures of the angles are m∠1 = 108° and m∠2 = 72°.

Given,

m∠1 = 3x°

m∠2 = (x + 36)°

We need to find the measure of these angles.

The straight line angle is 180 degrees.

If the angle is split the sum must be equal to 180 degrees.

We have,

m∠1 = 3x°

m∠2 = (x + 36)°

The figure is at a straight-line angle.

So we have,

m∠1  + m∠2 = 180°

3x° +  (x + 36)° = 180

3x + x + 36 = 180

4x + 36 = 180

4x = 180 - 36

4x = 144

x = 144/4
x = 36

Now,

- m∠1

= 3x

= 3 x 36

= 108

- m∠2

= x + 36

= 36 + 36

= 72

Thus the measures of the angles are m∠1 = 108° and m∠2 = 72°.

Answer:

4/8

Step-by-step explanation:

To do this, multiply the whole fraction by 4/4 (which is like multiplying by 1/1). So 1/2 x 4/4 becomes 4/8 :)

Answer:

3/8 i think

Step-by-step explanation:

 Try changing the top of the fraction to something divisible by 4, like 4 for example.

To do this, multiply the whole fraction by 4/4 (which is like multiplying by 1/1).

So 1/2 x 4/4 becomes 4/8.

if you consider each 1/8 to be 25% and 75÷3 equals 25+25+25:

So, 75% of 4/8 is 3/8.

Another quick way is to just multiply 1/2 by 3/4 (since you know 3/4 equals 75% {think 75/100 reduced is 3/4}) and you get 3/8 as well
