Answer:

y=15

Step-by-step explanation:

Because of the exterior angle theorem angle A plus angle b or equal to 146.

so you set 5y+3+4y+8=146 and solve

5y+3+4y+8=146

9y+11=146

9y=135

y=15

<h3><u>Answer:</u></h3>

Option C is correct.

<h3><u>Step-by-step explanation:</u></h3>

5y + 3 + 4y + 8 + (180 - 146) = 180
=> 9y + 11 + 34 = 180
=> 9y + 45 = 180
=> 9y = 180 - 45
=> 9y = 135
=> y = 135 ÷ 9
=> y = 15

<h3><u>Conclusion:</u></h3>

Hence, Option C is correct.

Find the coordinates of point P on →AB that partitions the segment into the given ratio AP to PB .

marysya [2.9K]

The line segment AB is divided at point P, which has coordinates P(0,-7.5)

A line segment is a section of a line that connects two locations to create a straight line or we can say that is connects two distinct points together to form a single line. It is extendable to either side.

Given are,

A line segment AB with coordinates of A(0,0 ) and B(-15,0) respectively

Two minor line segments, AP and PB, are created from the line segment AB by the provided point P

We must determine the dividing point's coordinates, or P.

We'll apply the formula provided,

The coordinates of the point P are given by = ( $\frac{x1+x2}{2}$ , $\frac{y1+y2}{2}$ )

Now, x1 = 0, x2 = 0, y1 = -15, y2 = 0

Putting values in the formula, we get

( $\frac{0+0}{2}$ , $\frac{0-15}{2}$ )

(0,-7.5)

Hence, the point P which partitions the line segment AB have coordinates as P(0,-7.5)

Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x?

jeka94

by Quadratic formula , $x^2 + 20 = 2x$ , values of x are $x = 1 \pm (1)i\sqrt{19}}$ . None of mentioned options are correct according to question!

<u>Step-by-step explanation:</u>

Here we have , expression x2 + 20 = 2x or , $x^2 + 20 = 2x$ .

We know that Quadratic formula is :

$x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$

$x^2 + 20 = 2x$

⇒ $x^2-2x+20=0$

$a=1\\b=-2\\c=20$

Putting this value in equation $x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$ :

⇒ $x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$

⇒ $x = \frac{-(-2) \pm \sqrt{(-2)^{2}-4(1)(20)}}{2(1)}$

⇒ $x = \frac{2 \pm \sqrt{4-80}}{2}$

⇒ $x = (\frac{2 \pm 2i\sqrt{19}}{2})$

⇒ $x = 1 \pm (1)i\sqrt{19}}$

Therefore , by Quadratic formula , $x^2 + 20 = 2x$ , values of x are $x = 1 \pm (1)i\sqrt{19}}$ . None of mentioned options are correct according to question!

3 Terrence uses pieces of wood that are 10 inches long to

Alchen [17]

Answer:

146 whistles

Step-by-step explanation:

First, convert 122 feet to inches, by multiplying it by 12

122(12)

= 1464

Divide this by 10 to find how many whistles he can make

1464/10

= 146.4

Since we can only have a whole number of whistles, we have to round down to 146.

So, he can make 146 whistles
