Here is your answer

B. $\sqrt{81}$

C. 9

REASON:

Let the side of square be a feet

Area of square = ${a}^{2}$

so,

${a}^{2}= 81$

$a= \sqrt{81}$

$a= 9 feet$

HOPE IT IS USEFUL

Lines x and y are parallel and are cut by the transversal b. If the measure of angle 1 is 57°, what is the measure of angle 6? E

lana [24]

Answer:

$\angle6=123$

Step-by-step explanation:

Given

Lines x and y

Transversal b

$\angle 1 = 57$

Required

Find $\angle 6$

From the attachment, $\angle1$ and $\angle7$ are vertically opposite.

This means that

$\angle 1 =\angle 7 = 57$

Similarly

$\angle 7$ and $\angle 6$ are supplementary angles

So:

$\angle7 + \angle6=180$

Make $\angle6$ the subject

$\angle6=180-\angle7$

$\angle6=180-57$

$\angle6=123$

The relationship between $\angle1$ and $\angle6$ is that they are supplementary angles because:

$\angle6+ \angle1=180$

The total cost for two family cars was $71,1482 the cost of one car was $38,295 write an equation using a variable to represent

Harrizon [31]

Your 71,1482 doesn't make sense. But regardless,

let x = the other car's cost.

You know the total spent and the cost of one car. So logically, if you subtract the two you'd get the price of the second car.

You can do $38,295 + c = $71,1482.

Or $71,1482 - $38,295 = c.

Can someone explain how to do this please?

Rufina [12.5K]

for the columns where is less than or equal zero, use the first line of the function to calculate the value of f(x)

${ ( \frac{1}{3} ) }^{ - 2} - 1 = 9 - 1 = 8 \\ { ( \frac{1}{3} ) }^{ - 1} - 1 = 3 - 1 = 2 \\ { ( \frac{1}{3} ) }^{ 0} - 1 = 1 - 1 = 0$

for every x greater than zero, use the second line to determine the value

${3}^{1} - 2 = 3 - 2 = 1 \\ {3}^{2} - 2 = 9 - 2 = 7$

hope this helps and gives some insight what to do.

if there are open questions left, feel free to ask them in the comments

have a beautiful day
