Answer:

Tennessee

Step-by-step explanation:

First, let's find out how much tax he paid...

$695.49-$649.99=$45.50

We can use this to set up an equation...

x%(649.99)=45.50

We can convert x% to x/100 since any percentage is just that number over one hundred...

$\frac{x}{100}*649.99=45.50\\\\\frac{649.99x}{100}=45.50$

Multiply 100 to both sides

$649.99x=4550$

Divide both sides by 649.99

$x$\approx$6.92$

This is closest to 7 (our answers is not exact since you can only have two decimal places in money), therefore he lives in D. Tennessee

Write the equation in slope intercept<br> through: (1,5), perp. to y=-1/10x + 3

Gwar [14]

First to get the equation you knew to understand one thing about perpendicular lines. The slope of the line is the opposite reciprocal of the perpendicular lines or the new slope is m = 10.

Then you use the formula
y = mx + b
you plug in your values from the point and the new slope.
(1,5) with new slope m
5= 10(1)+b
5-10=b
-5 = b
then make your new equation
y = 10x -5
that's your line that goes through point (1,5) and is perpendicular to the line given

Answer:

The area of the given figure is $66.5\ cm^2$ .

Step-by-step explanation:

To find out the area we should have to redraw the figure having nomenclature ABCDE and join BD. Thus we have a rectangle ABDE and a triangle BCD.

The new figure is in the attachment.

Given,

Length of AE = 7 cm

Length of DE = 8 cm

Length of CF = 11 cm

Solution,

Area of rectangle ABDE = $length\times breadth=length\ of AE\timeslength\ of DE$

Area of ABDE = $7\times8=56\ cm^2$

Now for triangle BCD,

Length of BD = length of AE = 7 cm

Length of GF = Length of DE = 8 cm

∴ Length of CG = Length of CF-Length of GF = $11-8=3\ cm$

Area of triangle BCD = $\frac{1}{2}\times base\times height}=\frac{1}{2}\times length\ of\ BD\times length\ of\ GF$

Area of BCD = $\frac{1}{2}\times7\times3=\frac{21}{2}=10.5\ cm^2$

Area of ABCDE = Area of ABDE + Area of BCD = $56+10.5=66.5\ cm^2$

Thus the area of the given figure is $66.5\ cm^2$ .

Find the value of x.

topjm [15]

9514 1404 393

Answer:

x = 136

Step-by-step explanation:

The angle marked x° is half the sum of the intercepted arcs:

x° = (130° +142°)/2 = 272°/2

x = 136

PLEASE ANSWER + BRAINLIEST!!

lora16 [44]

I'd like to see some of your own efforts here. This is the third time you've posted two "factor completelyl" problems, without sharing what you've already done.

<span>3v^2 - 8v - 16 cannot be reduced. Thus, your best choice to find roots is to apply the quadratic formula:

8 plus or minus sqrt( 64-4(3)(-16) )
v = ---------------------------------------------------
2(3)
8 plus or minus sqrt( 64 + 192 )
= ---------------------------------------------
6
8 plus or minus sqrt(256)
= -------------------------------------
6

= 8 + 16, all divided by 6, or 8 - 16, all divided by 6

= 4 or -8/6, or 4 or -4/3.

The factors are (v-4) and (v + 4/3).</span>
