Answer:

x = 1.6

Step-by-step explanation:

[tex] - 2.5(4x - 4) = - 6 \\ - 2.5(4x) - 2.5( - 4) = - 6 \\ - 10x + 10 = - 6 \\ - 10x + 10 - 10 = - 6 - 10 \\ - 10x = - 16 \\ \frac{ - 10x}{ - 10} = \frac{ - 16}{ - 10} \\ x = 1.6 \\ [/tex]

Classify the four angles of the quadrilateral

Answers

Answer:

<A = right angle

<B = acute angle

<C = obtuse angle

<D = acute angle

Step-by-step explanation:

Right angle = 90 degrees

Acute angle = less than 90 degrees

Obtuse angle = more than 90 degrees

∠A = 90° is a right angle, ∠B = 60° and ∠D  = 70° are acute angles,

and ∠C = 140° is an obtuse angle.

We have,

The quadrilateral ABCD.

There are four angles:

∠A = 90°
∠B = 60°

∠C = 140°

∠D = 70°

An acute angle is an angle whose measure is less than 90 degrees.

An obtuse angle is an angle whose measure is greater than 90 degrees but less than 180 degrees.

A straight angle is an angle whose measure is 90 degrees.

Using the definition,

∠A = 90°

This is a right angle.
∠B = 60°

This is an acute angle.

∠C = 140°

This is an obtuse angle.

∠D = 70°

This is an acute angle.

Thus,

∠A = 90° is a right angle, ∠B = 60° and ∠D  = 70° are acute angles,

and ∠C = 140° is an obtuse angle.

Consider the line - 5x+2y=8.
Find the equation of the line that is parallel to this line and passes through the point (-5, -3).
Find the equation of the line that is perpendicular to this line and passes through the point (-5, -3).

Answers

Answer:

The parallel equation is y=[tex]\frac{5}{2}[/tex]x-5.

The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.

Step-by-step explanation:

First solve for y.

-5x+2y=8

2y=5x+8

y=[tex]\frac{5}{2}[/tex]x+4

A line is parallel if it has the same slope, but different y-intercepts.

The y-intercept of the given point is -5, so the new slope will be y=[tex]\frac{5}{2}[/tex]x-5

To find a perpendicular line, you find the negative reciprocal of the given slope.

So you find [tex]\frac{-1}{\frac{5}{2} }[/tex], which is equal to [tex]\frac{-2}{5}[/tex].

The perpendicular equation is y=[tex]\frac{-2}{5}[/tex]x-5.

Answer:

Step-by-step explanation:

A straight line will be parallel to another straight line only if their slopes are equal .A straight line will be perpendicular to another straight line only when the product of their slopes is -1 Part ALet 's bring the function  -5x+2y=8 to the standard form 2y=8+5x y=2,5x+4 A parallel line passes through a point  (-5; -3); and this meansy=2,5x+b 2,5*(-5)+b=-3 b=9,5 y=2,5x+9,5  -straight parelenai straight y=2.5x+4 Part B Let 's bring the function  -5x+2y=8 to the standard form y=2,5x+4 y=kx+b  And we know k*2,5=-1=> k=-0,4 y=-0,4x+b -0,4*(-5)+b=-3b=-1y=-0,4x-1 - Straight perpendicular to the straight line y=2.5x+4

A running tap dispenses 0.14 gallons of water every second. How many pints of water is dispensed after 50 seconds? Show your work.

Answers

Answer:

56

Step-by-step explanation:

0.14 gallons/sec * 50 sec = 7 gallons

There are 8 pints per gallon.

7 gallons * 8 pints/gallon = 56 pints

Given that a running tap dispenses 0.14 gallons of water every second. Using unitary method, 56 pints of water is dispensed after 50 seconds.

What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Water dispensed every second =  0.14 gallons

Water dispensed after 50 seconds = 0.14 * 50 = 7 gallons = 7 * 8 = 56 pints (1 gallon = 8 pints)

Please help me find the answer to the attached photo

Answers

Ok, I shall help.
Please give me brainliest answer.
So first step
25x+8+9x+2=180
We can do this because they are interior angles which add to 180 degrees.
So now we simplify.
25x+9x+2+8=180
34x+10=180
Minus 10 from both sides to get x.
34x = 170
Divide by 34 to only find x.
This leaves x=5 now we find y.
9x+2=7y+5
We can make these two equal because they are alternate angles which are always equal.
Now as we established earlier x is 5 so we substitute.
9(5)+2=7y+5
45+2=7y+5
47=7y+5
Now we minus 5 from both sides to leave 7y
47-5=7y
42=7y
Now we divide by 7 to only get y.
Y=6
X=5

Answers

Answer:

[tex]x=6\\y=12[/tex]

Step-by-step explanation:

To find the value of x you can use sin rule

[tex]sin(60)=\frac{oppoaite}{hypotenuse}\\\frac{\sqrt{3} }{2} =\frac{x}{4\sqrt{3} } \\[/tex]

Use cross multiplication

[tex]4*\sqrt{3} *\sqrt{3} =2x\\4*3=2x\\12=2x\\\frac{12}{2} =\frac{2x}{2} \\6 =x[/tex]

To find the value of y you have to use sin rule again

[tex]sin(30)=\frac{opposite}{hypotenuse}\\\frac{1}{2} =\frac{x}{y} \\\frac{1}{2} =\frac{6}{y} \\[/tex]

Use cross multiplication

[tex]y=6*2\\y=12[/tex]

Hey, so I got
x = 5.9 units (just round it to 6)
y= 11.8 units (round it to 12)

Steps:

1) Use Soh Cah Toa to identify the unknown sides.

The side across the angle is the opposite. Therefore, the x side is opposite.
4√5 = 6.9 ( this side is the hypotenuse).
So we have the opposite side and the hypotenuse side. Therefore, we will use sine

2) Sin theta = opp/hyp
Sin 60 = opp/6.9

Multiply both sides by 6.9

6.9(sin60) = opp
5.9 = opp

3) now that you have side x, we will use x to figure out side y.

Identify the sides first. Side x is opposite and side y is the hypotenuse. Use sine to solve for side y

Sin theta = opp/hyp
Sin 30 = 5.9/hyp
0.5 = 5.9/hyp

Divide 0.5 and bring it over to the other side.

= 5.9/ hyp ÷ 0.5/1
= 5.9/hyp x 1/0.5
= 5.9/0.5
= 11.8 units (side Y)

the answer is x=12

start by checking what the angles are, in this case they are not equal, but they do add up to 180. so plug what you know into an equation.
(4x+8) + (9x+16) = 180
then separate the common terms
4x+8+9x+16=180
then add the like terms together
13x+ 24=180
subtract 24 from 180 to get the x variable alone
13x= 156
then divide each side by 13 to get the x value, which is twelve.
x=12
