Answer:

4 /9

Step-by-step explanation:

All we have to do is evaluate the options in other to compare the result :

4 / 10 = 0.4

4 / 9 = 0.4444444...

9/ 4 = 2.25

Answer:

121/4

Step-by-step explanation:

To complete the square, we have to work with the coefficient of x

We have to divide the coefficient of x by 2, square it and add it to both sides

So we divide 11 by 2; which is 11/2; then square it

we have this as 121/4

This number is what we are going to have added

Answer:

3/5

Step-by-step explanation:

both 6 and 10 divide by 2. divide each number by 2 and you get 3/5

Answer:

3/5

Step-by-step explanation:

To find the simplest form of 6/10, you must reduce the fraction.

I did this by dividing both the numerator and denominator by 2, therefore making it 3/5, (because it cannot be reduced evenly anymore).

Answer:

C

Step-by-step explanation:

Answer:

it will take 3 yrs for the value of camera to reach $162.

Step-by-step explanation:

Pd = P(1-R/100)^T

162 = 384(1-25/100)^T

162/384 = (3/4)^T

27/64 = (3/4)^T

(3/4)^3 = (3/4)^T

T = 3

Answer:

this represents: exopnential decay, the rate of growth or decay is equal to: 0.25, value of the camera each year is: 0.75, it will take 3 years.

Step-by-step explanation:

The probability of getting blue with small is 3/20 because 3 is the small quantity and 20 is the total blue.

Give details according to the question :

Total number of blue

Sum of larger and small  = 17+3 = 20

Total number of red

Sum of large and small = 8+12 = 20

Now,

Probability :

The probability formula is used to compute the probability of an event occurring.

P(A) = n(A)/n(S)

Where,

P(A) is the probability of an event “A”

n(A) is the number of favorable outcomes

n(S) is the total number of events in the sample space

Note: Here, the favorable outcome means the outcome of interest.

n(A) is the number of favorable outcomes = 3

n(S) is the total number of events in the sample space = 20

P(Small and Blue)= 3/20

Answer:

y = - x² - 4x + 13

Step-by-step explanation:

The equation of a parabola in standard form is

y = ax² + bx + c ( a ≠ 0 )

Given

y = - (x + 2)² + 17 ← expand factor using FOIL

   = - (x² + 4x + 4) + 17 ← distribute parenthesis by - 1

   = - x² - 4x - 4 + 17 ← collect like terms

y = - x² - 4x + 13

Answer:

y = -x² -4x +13

Step-by-step explanation:

y = - ( x+2)² + 17

y = - x² -4x -4 +17

y = -x² -4x +13

Answer:

Given that a worker earns a 3% increase in her annual salary for each of 5 years, and they plan to continue working in their position for an additional N years, if they continue to earn a 3% increase in their annual salary, to determine what statement could describe the expression that can be used to calculate the total percent increase in their annual salary from the first year to the last year the following calculation should be performed:

1 + 0.03 (interest rate) ^ N (number of years) = final interest rate

1.03 ^ N = Final interest rate

Thus, for example, if it were invested for 5 years, the equation would operate as follows:

1.03 ^ 5 = X

1.16 = X

The total percent increase in their annual salary from the first year to the last year is [tex](1.03)^n[/tex].

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the annual salary of the worker increases at a rate of 3%. therefore, the salary of the worker increases compounded at a rate of 3% annually. Therefore, the salary of the worker after n number of years can be written as,

[tex]A = P(1+\dfrac{r}{100})^n[/tex]

where A is the final salary of the worker, P is the initial salary of the worker, r is the rate at which the salary is increasing, and n is the number of years.

Substituting the values in the formula,

[tex]A = P(1+\dfrac{3}{100})^n\\\\A = P(1.03)^n[/tex]

Hence, the total percent increase in their annual salary from the first year to the last year is [tex](1.03)^n[/tex].

Answer:

124 degrees

Step-by-step explanation:

We know that a straight line is equal to 180 degrees. Therefore, all of these angles combined have to be equal to 180 degrees. This means the equation will be 3x+94+x+30+2x-4=180. Combine like terms to get 6x+120=180. 6x=60. x=10. Now that we know x, we plug it into the equation to find angle AOC. This will make the equation 3(10)+94. This is equal to 30+94 which is equal to 124. Therefore, angle AOC is equal to 124 degrees.
