Round each fraction to the nearest half and find the estimate.

erastova [34]

Answer: The result is one half ( $\frac{1}{2}$ )

Step-by-step explanation:

We have the following expression:

$\frac{2}{6}+\frac{1}{6}$

Since both fractions have the same denominator, we can just add both numerators and keep the denominator:

$\frac{2+1}{6}=\frac{3}{6}$

Dividing numerator and denominator by $3$ :

$\frac{\frac{3}{3}}{\frac{6}{3}}=\frac{1}{2}$ This is the result

Solve the equation, if possible. (If all real numbers are solutions, enter REALS. If there is no solution, enter NO SOLUTION.) x

UkoKoshka [18]

Answer:

REALS. all real numbers are solution for the equation

Step-by-step explanation:

for the equation

x² = (x + 3)*(x − 3) + 9

distributing the terms in the parenthesis

x² = (x + 3)*(x − 3) + 9 = [x² - 3*x + 3*x - 3*3 ] + 9

x² = x² - 9 + 9

0 = 0

since this statement will be true regardless of the value of x , then the equation has solution for all real numbers .

Find the distance between the two points in simplest radical form.<br> (7,-1) and (9,-9)

storchak [24]

Answer:

$\sqrt{68}$

Step-by-step explanation:

(7 , -1) = (x1 , y1)

(9 , -9) = (x2 , y2)

distance formula = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

= $\sqrt{(9 - 7)^2 + (-9 - (-1))^2}$

= $\sqrt{2^2 + (-9 + 1)^2}$

= $\sqrt{4 + (-8)^2}$

= $\sqrt{4 + 64}$

= $\sqrt{68}$

The circle has a radius of 11 cm. What is the area of the shaded sector? Use 3.14 for π, and round your answer to the nearest te

Alenkasestr [34]

Answer:

C) 253. 3 cm²

Step-by-step explanation:

1. Sector area formula can be in degrees or radians. I will use degrees because we are given 240 degrees as a unit.

2. SA= $\frac{x}{360}$ times $\pi r^{2}$ where x is the degrees of the sector

3. 240/360 times 3.14(11)²

4. 0.66666667 times 379.94

5. approximately 253. 3 cm²
