Find the value X and Y

Mathematics
1 answer:
Helga [31]3 years ago
5 0

Hi there! :)

<u>Answer:</u>

X = 30

Y = 97


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

The lines on each side of the figure means that the side with 1 line is equal to the other side with 1 line and the side with 2 lines is equal to the other side with 2 lines.

Let's start by the sides with 1 line:

4x = 3x + 30

Now solve this equation by isolating "x":

4x = <u>3x</u> + 30

Subtract 3x from each side of the equation: 4x - 3x = x

x = 30


Now that you know the value of "x", you can go ahead and find the value of "y" by replacing the "x" in the expression of the side with 2 lines and isolating the equation by isolating "y":

y = 7 + 3<u>x</u>

y = 7 + <u>(3 × 30)</u>

y = <u>7 + 90</u>

y = 97


There you go! I really hope this helped, if there's anything just let me know! :)

Find the components of the vertical force Bold Upper FFequals=left angle 0 comma negative 10 right angle0,−10 in the directions
quester [9]

Solution :

Let $v_0$ be the unit vector in the direction parallel to the plane and let $F_1$ be the component of F in the direction of v_0 and F_2 be the component normal to v_0.

Since, |v_0| = 1,

$(v_0)_x=\cos 60^\circ= \frac{1}{2}$

$(v_0)_y=\sin 60^\circ= \frac{\sqrt 3}{2}$

Therefore, v_0 = \left

From figure,

|F_1|= |F| \cos 30^\circ = 10 \times \frac{\sqrt 3}{2} = 5 \sqrt3

We know that the direction of F_1 is opposite of the direction of v_0, so we have

$F_1 = -5\sqrt3 v_0$

    $=-5\sqrt3 \left$

    $= \left$

The unit vector in the direction normal to the plane, v_1 has components :

$(v_1)_x= \cos 30^\circ = \frac{\sqrt3}{2}$

$(v_1)_y= -\sin 30^\circ =- \frac{1}{2}$

Therefore, $v_1=\left< \frac{\sqrt3}{2}, -\frac{1}{2} \right>$

From figure,

|F_2 | = |F| \sin 30^\circ = 10 \times \frac{1}{2} = 5

∴  F_2 = 5v_1 = 5 \left< \frac{\sqrt3}{2}, - \frac{1}{2} \right>

                   $=\left$

Therefore,

$F_1+F_2 = \left< -\frac{5\sqrt3}{2}, -\frac{15}{2} \right> + \left< \frac{5 \sqrt3}{2}, -\frac{5}{2} \right>$

           $= = F$

Given:
Westkost [7]

Answer: (A) If it is a bib, then it is a bab

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

p: The bib is a bub.

Rewrite it as: If it is a bib, then it is a bub.

  • hypothesis: It is a bib
  • conclusion: It is a bub

q: The bub is a bab.

Rewrite it as: If it is a bub, then it is a bab

  • hypothesis: It is a bub
  • conclusion: It is a bab

The conclusion of p equals the hypothesis of q so the Law of Syllogism can be applied  --> hypothesis of p → conclusion of q

yawa3891 [41]

Answer:

16x - 48y +24

Step-by-step explanation:

We can use the distributive property to expand:

  1. 8(2x - 6y + 3)
  2. 8 x 2x - 8 x 6y + 8 x 3
  3. 16x - 48y + 24

Hope this helps!!
