1.(4/9)^2=(4/9)(4/9)=16/81
2. Make all denominators the same so 1/3=6/18 2/9=4/18 and finally, 1/2=9/18
3. Add the three fractions together to get 19/19 which is just 1 however for this question we shall leave it as 19/19
4. Remember KFC so our question becomes 16/81 x 19/19
5. Work this out as 16/81

notsponge [240]

<span>the smaller angle is 2x = 2 times 18 = 36 degrees.
the larger angle is 3x = 3x = 3 * 18 = 54 degrees. </span>

How to estimate 2 5/6, first one to answer will be marked brainliest

RideAnS [48]

Answer:

If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:

Step-by-step explanation:

2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.

<u>This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. </u>0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.

I would then say that the estimate of 2 5/6 is 2.83.

Points If a person invests $250 at 9% annual interest, find the approximate value of the investment at the end of 15 years.

AfilCa [17]

Principal Amount = P = $250

Interest Rate = r = 9% = 0.09

Time in years = t = 15 years

Value of investment = A = ?

The formula to calculate the value on investment as a result of annual interest is:

$A=P(1+r)^{t}$

Using the values in the above formula, we get:

$A=250(1+0.09)^{15}\\ \\ A=\$ 910.62$

Thus, at the end of 15 years the value of the investment will be $ 910.62.

A jet travels 584 miles in 4 hours. At this rate how far could the jet fly in 13 hours?what is the rate of speed of the jet

ankoles [38]

Answer:

The speed at which jet travel is 44.92 miles per hour

The distance cover at 44.92 mph is 583.96 miles .

Step-by-step explanation:

Given as :

The distance cover by jet = d = 584 miles

The time taken b the jet to cover 584 miles = t = 13 hours

Let The speed at which jet travel = s

So, Speed = $\dfrac{\textrm distance}{\textrm time}$

or, s = $\dfrac{\textrm d}{\textrm t}$

Or, s = $\frac{584}{13}$

∴ s = 44.92 mph

So , The speed at which jet travel = s = 44.92 miles per hour

Now, At The speed of 44.92 mph

Let The distance cover at this speed = d' miles

And for the distance of d' , the time taken= 13 hours

Now, Distance = Speed × Time

So, d' = 44.92 mph × 13

Or, d' = 583.96 miles

So, the distance cover at 44.92 mph = d' = 583.96 miles

Hence The speed at which jet travel is 44.92 miles per hour

And The distance cover at 44.92 mph is 583.96 miles . Answer
