Answer:

250

Step-by-step explanation:

Step 1: Round to the nearest tenth

2 4 5

hundreds tens ones

If the ones place is higher than 5, that means that the tens place will round up by one and the ones place will go to zero. If it is below 5, the tens place won't change, but the ones place will still go to zero.

245 -> Since the ones place is above 5, that means that we will round up

250

Answer: 250

-2 divided by 2 5/6 (make a fraction and simplify)

seropon [69]

Answer:

−12/17

Step-by-step explanation:

This is the answer because:

1) First, convert 2 5/6 to an improper fraction

2 5/6 = 17/6

2) Next divide -2/1 and 17/6

3) The reciprocal of 17/6 is 6/17

4) -2/1 ÷6/17 is -12/17

Hope this helps!

Let f(x) = 9x3+ 21x2^ - 14 and g(x) = 3x + 1. Find " f (x) over g (x)

kondor19780726 [428]

Answer:

$\frac{f(x)}{g(x)}=3x^2+6x-2-\frac{12}{3x+1}$

Step-by-step explanation:

The first function is $f(x)=9x^3+21x^2-14$

The second function is $g(x)=3x+1$ .

$\frac{f(x)}{g(x)}=\frac{9x^3+21x^2-14}{3x+1}$

We perform the long division as shown in the attachment to obtain the quotient as: $Q(x)=3x^2+6x-2$ and remainder $R=-12$ .

Therefore:

$\frac{f(x)}{g(x)}=3x^2+6x-2-\frac{12}{3x+1}$

where $x\ne -\frac{1}{3}$

Answer:

$153\ in^2$

Step-by-step explanation:

1. Approach

Divide the given figure up into two simple figures, a trapezoid, and a rectangle. Calculate the area of each figure by using their respective area formula. Then add up the results to get the value for the area of the entire figure.

2. Area of the trapezoid

The first figure is a trapezoid, calculate its area by using the following formula,

$A_t= \frac{b_1+b_2}{2}(h)$

Where parameters ( $b_1$ ) and ( $b_2$ ) represent the base of the trapezoid, and ( $h$ ) represents the height. Substitute in the given values and solve.

$A_t = \frac{16 + 5}{2}(10)$

Simplify,

$=\frac{21}{2}(10)$

$=10.5(10)$

$=105$

3. Area of the rectangle

The other figure formed by the partition of the two figures is a rectangle. The formula to find the area of a rectangle is the following,

$A_r =(b)(h)$

Where ( $b$ ) represents the base of the figure, and ( $h$ ) represents the height of the figure. Substitute in the values for the given parameters and solve,
