Answer:

Step-by-step explanation:

The bar above the 3 in the 2.3 means that the 3 repeats indefinitely and the number is really 2.333333...which can also be 2 1/3 since 0.33333 = 1/3.

3 2/3 + 2 1/3

1/3 and 2/3 make 1

3 and 2 make 5

1 + 5 = 6

Adding together we get 6, so that is your answer.

I'm always happy to help :)

Answer:

Step-by-step explanation:

The overbar means the digit repeats indefinitely. The repeating decimal 0.333... is equivalent to 1/3, so this is the simple addition ...

3 2/3 + 2 1/3 = 5 3/3 = 6

_____

<em>Comment on the repeating decimal</em>

1/3 = 0.3333... repeating is one of the first decimal equivalents you learn.

If you're into repeating decimals. you may have learned how to convert them to fractions:

x = 0.3333... repeating . . . . . . . give a name to the value

10x = 3.3333... repeating . . . . . multiply by 10^p where p is the number of digits in the repeating pattern

10x - x = 3.3333... - 0.3333... = 3 . . . . . subtract: the repeating portions cancel

9x = 3 . . . . . . . . . .simplify

x = 3/9 = 1/3 . . . . .divide by the x-coefficient; simplify

Enita is factoring the expression 32 a b minus 8 b. She determines the GCF and writes the factored expression as 8 b (4 a minus

sattari [20]

This shows that the greatest common factor is 8, Hence Venita's error is that she incorrectly determined the GCF.

<h3>Greatest common factor</h3>

Given the following expression

32ab - 8

Find the factors of each terms

32ab = 8 * 4. * a * b

8 = 8 * 1

Since 8 is common to both factors, hence

32ab - 8 = 8(4ab -1)

This shows that the greatest common factor is 8, Hence Venita's error is that she incorrectly determined the GCF.

Find the missing measures of the following rectangle

Allushta [10]

Answer:

see explanation

Step-by-step explanation:

In a rectangle

• All angles are right angles

• the diagonals are congruent

In Δ WXV the sum of the 3 angles = 180°

∠ WXZ = ∠ XWY = $\frac{180-64}{2}$ = $\frac{116}{2}$ = 58°

∠ YXZ = 90° - 58° = 32°

∠ WVZ = 180° - 64° = 116° ( adjacent angles are supplementary )

∠ XWZ = 90° ( by definition of rectangle )

∠ XZY = ∠ WXZ = 58° ( corresponding angles )

H(x)=1/8x^3-x^2<br><br> Over which interval does h have a positive average rate of change?

lara31 [8.8K]

Answer:

$(-\infty,0)\cup(\frac{16}{3},\infty)\\That \ is x\frac{16}{3}$

Step-by-step explanation:

$h(x)=\frac{1}{8}x^{3} -x^{2} \\\\Differentiate \ h(x) \ with \ respect \ to \ x\\h'(x)=\frac{3}{8}x^{2} -2x$

For positive rate of change $h'(x)>0$

$\frac{3}{8} x^{2} -2x>0\\x(\frac{3}{8}x-2)>0\\\\ When \ x0 \ (multiplication \ of \ two \ positives \ is \ positive)\\\\h'(x)>0 \ when \ x\frac{16}{3} \\\\$
