Round 99.20 to the nearest ten

2 answers:

I believe it would be 100 because the 9 in 99 would be the rounding spot and if you look to the right of it its another 9 which is greater than five so that would round up to 100

When your rounding anything above five goes up, while anything below five rounds down.

When your rounding you must look at the number to the right of the number your rounding to so you could figure out the answer.

Once you decide if the number is going up or down, eliminate the number you used to determine if you should add one or leave it the same.

Step one: Analyze the numbers, the ten in 99.20 would be 90, so you would look at the digit to the right of the 99.20 which would be 9 ones.

Step two: Check to see if the number is higher than 5 or lower than 5. 9 is higher than five, so it goes up.

Step three: Bump up the second 9 in 99.20, that would make the number 100.20.

Step four: Eliminate anything after the first 9 (In this case there isn't anything)

And your done! I hope this helped, if so please mark this the brainliest answer!

Function A is a quadratic function with a vertex at (3, 4) and a leading coefficient of -1 Function B has the equation y = |x +

skad [1K]

With the information given, we deduce that the parabola is

$y=-(x-3)^2+4 = -(x^2-6x+9)+4 = -x^2+6x-5$

Reflecting a function over the x axis means to change its sign. After the reflection, the parabola becomes

$y=x^2-6x+5$

And to shift down a function, you subtract the shift from the equation: the equation becomes

$y=x^2-6x+5-2=x^2-6x+3$

Similarly, the other function is reflected over the x axis (sign change) and shifted up 3 (add 3 to the equation):

$|x+2|\mapsto -|x+2|\mapsto -|x+2|+3$

In order to compute the y intercept, we simply have to evaluate the functions at x=0: for the parabola we have

$y(0)=3$

For the other function, we have

$y(0)=-|2|+3=-2+3=1$

<em>In the next year, Anthony worked 2,084 hours</em>

Step-by-step explanation:

Anthony worked 1,697 hours in 2010.

We also know Anthony worked 22.8% more hours than in 2010.

The problem requires to calculate how much did Anthony work in the next year.

It can be calculated as follows:

Take 22.8% of 1,697:

$22.8 * 1,697 / 100 = 386.916\approx 387\ hours$

Now calculate by adding it to the original number of hours:

1,697 + 387 = 2,084 hours

In the next year, Anthony worked 2,084 hours

You know that the battery in your alarm clock is going to run out of power soon. If it runs out within the next 24 hours, what i

aivan3 [116]

The probability of an event is given by the number of favorable outcomes divided by the total number of outcomes. Here the event is the alarm clock running out of power. There are 24 hours during which the power can go out. You are asleep during 8 of these. A "favorable" outcome in this case is the power going out while you are sleeping -- that is, during one of those 8 hours. This makes the probability that the power goes out while you are sleeping 8/24.
