A is an absolute value if it is greater than zero. This simply means that an absolute value number will always be greater than zero. This is because absolute value is the distance from 0 on a number line. Keep in mind that distance cannot be negative. For example, look at the numbers 5 and -5. 5 is 5 spaces from 0, and -5 is also 5 spaces from 0, not -5 spaces from 0. Put simply, an absolute value number that is greater than 0, will always be positive.

Given that f (x)=x/2+5 find f(2)

fgiga [73]

Answer:

f(2) = 6

Step-by-step explanation:

Given that the function

$f(x) = \frac{x}{2} + 5$

Put x=2

$f(2) = \frac{2}{2} + 5 = 1 +5 = 6$

f(2) = 6

David is making a wall out of bricks. Each brick is 2/3 foot long. There are 20 bricks lined up end to end to make the wall. Wha

Law Incorporation [45]

The total length of wall is 160 inches

<em><u>Solution:</u></em>

Given that,

$Length\ of\ each\ brick = \frac{2}{3}\ foot$

1 feet = 12 inches

Therefore,

$Length\ of\ each\ brick = \frac{2}{3} \times 12\ inches = 8\ inches$

There are 20 bricks lined up end to end to make the wall

<em><u>To find: Total length of wall in inches</u></em>

$Total\ length\ of\ wall = \text{length of each brick } \times \text{ total number of bricks}$

Thus we get,

$Total\ length\ of\ wall = 8 \times 20\\\\Total\ length\ of\ wall = 160\ inches$

Thus total length of wall is 160 inches

What is the measure of angle R?

amid [387]

Answer:

52.5

Step-by-step explanation:

Since this is an isosceles triangle, the base angles are the same

The three angles add to 180

R+ T + S = 180

3x+30 + 3x+30 + 12x-15 = 180

Combine like terms

18x +45 = 180

Subtract 45 from each side

18x+45 - 45 = 180-45

18x =135

Divide each side by 18

18x/18 = 135/18

x = 7.5

We want angle R

R = 3x+30

= 3( 7.5) +30

22.5 +30

52.5
