Answer:

Below.

Step-by-step explanation:

Each piece is 12 / 7 = 1 5/7 feet long.

That is 1.714 feet to nearest thousandth or 1 foot 8.57 inches to nearest 1/100.

Answer:

20 4/7 inches

Step-by-step explanation:

Take 12 feet and convert to inches

1 ft = 12 inches

12 * 12 = 144 inches

Divide by 7

144/7 =20 with 4 left over

20 4/7 inches

Find the values of x and y<br><br> x=42, y=26.3<br> x=47, y=30<br> x=42, y=30<br> x=47, y=26.3

olga55 [171]

Answer:

x = 42, y = 30

Step-by-step explanation:

From the given figure, we have to find the value of x and y.

The measurement of an angle on a straight angle is 180 degrees.

Using this concept, we have

$3y+5+2x+1=180\\3y+2x=174....(1)$

Now, we know that the sum of consecutive interiors angles is 80 degrees. Hence, we have

$3y+5+85=180\\3y+90=180\\3y=90\\y=30$

Plugging the value of y in equation (1)

$3(30)+2x=174\\90+2x=174\\2x=84\\x=42$

Hence, the values of x and y are

x = 42, y = 30

A line passes through the point (-1, -7) and has a slope of -8.

mr_godi [17]

Answer:

y = -8x -15

Step-by-step explanation:

It can be useful to start with the point-slope form when you are given a point and a slope.

y -k = m(x -h) . . . . . line with slope m through point (h, k)

For the given line, this equation is ...

y +7 = -8(x +1)

y = -8x -8 -7 . . . . eliminate parentheses, subtract 7

y = -8x -15 . . . . . slope-intercept form

svet-max [94.6K]

Answer: 187500

Step-by-step explanation:

Interest= principal ×rate×time/100

Let interest be I

Principal be P

Rate be r

Time be t

So we have

I=p×r×t/100

P in the question is 150000

T is 1year

R is 25%

Substitute for the values

I=150000×1×25/100

Interest= 37500

To know the exact cost now

Add the interest to the principal cost

Exact value=interest +principal

Exact value =37500+150000

Exact value=187500

The cost of the house now is=187500

In ∆XYZ, m∠X = 152, y = 15, and z = 19. Find side x and the measure of angle Y to the nearest tenth

solong [7]

The measure of the side $x$ is approximately 33 and the measure of angle $Y$ is approximately 12.321°.

<h3>How to find a missing angle in a triangle by law of sine and law of cosine</h3>

In this problem we must apply the law of cosine and the law of sine to determine the angle Y:

<h3>Law of cosine</h3>

$x = \sqrt{y^{2}+z^{2}-2\cdot y\cdot z\cdot \cos X}$

$x = \sqrt{15^{2}+19^{2}-2\cdot (15)\cdot (19)\cdot \cos 152^{\circ}}$

$x \approx 33$

$\frac{\sin Y}{y} = \frac{\sin X}{x}$

$Y = \sin^{-1}\left(\frac{y}{x}\cdot \sin X \right)$

$Y = \sin^{-1}\left(\frac{15}{33}\cdot \sin 152^{\circ} \right)$

$Y \approx 12.321^{\circ}$

The measure of the side $x$ is approximately 33 and the measure of angle $Y$ is approximately 12.321°. $\blacksquare$
