Answer:

12.7 miles

Step-by-step explanation:

Note the place values:

12.654

1 (tens value)

2 (ones value)

6 (tenths value)

5 (hundredths value)

4 (thousandths value)

You are rounding to the nearest tenths value. Note that when rounding, you look at the value directly next to the one you are solving for. If the digit is 5 or greater, round up. If it is 4 or less, round down.

In this case, the hundredths value is a 5, so round up.

12.654 miles rounded to the nearest tenths value is 12.7

12.7 miles is your answer.

Answer:

3g + 8 = T

Step-by-step explanation:

3g + 8 = T because since Deanna estimates 3 slices for each guest, you would times the # of guests by 3, which is 3g. Then you would add 8 because Deanna will need extra 8 slices for the unexpected guests. This equation would tell you how many slices Deanna needs in total.

Hope this helps :D

<h3>What is probability?</h3>

The probability exists in the analysis of the possibilities of happening of a result, which exists acquired by the ratio between favorable cases and possible cases.

Conditional probability directs to the possibility that some outcome happens given that another possibility contains also occurred.

Justine only goes when her friend goes [Conditional probability]

Independent events exist as those possibilities whose occurrence exists not dependent on any other event.

Dependent events exist that depend upon what occurred before.

Let f(x)=x2+14x+48. What are the zeros of the function? Enter your answers in the boxes.

mina [271]

Remember that to find the zeroes of a quadratic expression of the form $a x^{2} +bx+c$ we could either factor it or use the quadratic formula. When $a=1$ , like in our case, is often way easier and faster factor the expression than using the quadratic formula. The only thing we need to do to factor the expression is find tow number whose product is 48 and its sum is 14; those numbers are 6 and 8. $(6)(8)=48$ and $6+8=14$ . Now we can factor our quadratic like follows:
$x^{2} +14x+48=(x+6)(x+8)$
Since we are trying to find the zeroes of the function, we are going to set each one of our factored binomial equal to zero and solve for x:
$x+6=0$
$x=-6$
and
$x+8=0$
$x=-8$

We can conclude that the zeroes of the function $f(x)= x^{2} +14x+48$ are $x=-6$ and $x=-8$ .

Judy went shopping for school supplies. She bought a binder for $1.38, a pack of pencils for $2.05, and a box of erasers for $3.

Annette [7]

Answer:

The change received by Judy is $ 2.69.

Step-by-step explanation:

Bill paid = $ 10

Cost of binder = $ 1.38

Cost of pack of pencils = $ 2.05

Cost of box of erasers = $ 3.88

Total cost of the school supplies = $ 1.38 + $ 2.05 + $ 3.88 = $ 7.31

The amount of change Judy received = $ 10 - $ 7.31 = $ 2.69
