Answer:

x = 27°

Step-by-step explanation:

Because of the two parallel lines, we can conclude that

corner DAB = corner FDE = 2x

In ∆DAB

Corner DAB = 2x

Corner BDA = 2x (given)

Corner ABD = 72 (given)

The sum of three corners in any trianle, adds up to 180°.

So if one corner is 72° and the other two corners are the same, then the two corners together, must be 180-72 = 108°.

For each corner that is 108/2= 54

so corner BDA = 54° and also corner DAB = 54°.

Given was BDA = 2x and BDA = 54°

so 2x = 54°

then x = 27°

The correct answer is option (D).

A triangle is a polygon with 3 sides.

Given the triangles ΔABE and ΔACD.

The triangle ΔABE is a smaller-scaled replica of the triangle ΔACD, therefore, the triangles ΔABE and ΔACD are similar triangles.

Since the triangles are similar, the ratio of their corresponding sides is proportional.

Therefore,

BE/CD = AB/AC

Or, BE = CD· (AB/AC)

Hence, the correct answer is option (D).

Answer:

$82.50

Step-by-step explanation:

Given that the unit rate is $13.75 per hour,

1 hour -----> $13.75

6 hours -----> $13.75 x 6 = $82.50

Answer:

speed = distance/time

distance = 60 miles

time = 1.5 h

speed = 60/1.5

= 40 miles per hour

so the answer in the pic is the correct answer

The equation of line is y = 40x and the unit rate of speed of travel is given by A = 40 mph

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 0 , 0 )

Let the second point be Q ( 1.5 , 60 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 60 / 1.5 )

Slope m = 40 miles per hour

So , the speed of the travel is 40 mph

And , the equation of line is y - y₁ = m ( x - x₁ )

y = 40x , where x is the number of hours

Hence , the speed of the travel is 40 miles per hour

Answer : The area of given rectangle is p² - 7p

Step-by-step explanation :

Formula used to calculate the area of rectangle is:

Area of rectangle = length × breadth

Given:

Length = (p-7)

Breadth = p

Area of rectangle = length × breadth

Area of rectangle = (p-7) × p

Area of rectangle = p² - 7p

Therefore, the area of given rectangle is p² - 7p

Answer:

x = -2

Step-by-step explanation:

2x + 5 = 1 ( subtract 5 from both sides )

2x = 1-5

2x = -4 ( divide both sides by 2 )

2x ÷ 2 = -4 ÷ 2

x = -2

Answer: x = -2

Step-by-step explanation: To solve for x, we must first isolate the term containing x which in this problem is 2x.

Since 5 is being added to 2x, we subtract 5

from both sides of the equation to isolate the 2x.

On the left, the +5 and -5 cancel out and on the right, 1 - 5 is -4.

So we have 2x = -4.

Now we can finish things off by just

dividing both sides of the equation by 2.

On the left, the 2's cancel and on the right, -4 divide by 2 is -2.

So x = -2.

Step-by-step explanation:

Answer:

a) 10.7 cm

b) 11.6 cm

c) 29.9 cm²

Step-by-step explanation:

a) sin(α)/a = sin(β)/b

sin(∠BCD)/BD = sin(DBC)/DC

sin(41°)/BD = sin(55°)/13.4

BD = 13.4*sin(41°)/sin(55°) = 10.73 cm ≈ 10.7 cm

b) From ΔBCD , ∠BDC = 180-(41+55) = 84°

∠ABD and ∠BDC are alternate interior angles, so they are congruent, and

∠ABD = ∠BDC  = 84°

AD²= AB² + BD² - 2*AB*BD*cos (∠ABD) =

= 5.6² + 10.73² - 2*5.6*10.73*cos(84°) = 133.93 cm²

AD =√(133.93) ≈11.6 cm

c) Area(ADB) = (1/2)*AB*BD*sin(∠ABD)=(1/2)*5.6*10.73*sin(84°) ≈ 29.9 cm²

Complete question is:

Nancy is checking to determine if the expressions x+4+x and 6+2x-2 are equivalent. When x=3 , she correctly finds that both expressions have a value of 10. When x = 5, she correctly evaluates the first expression to find that x + 4 + x = 14. What about the second expression?

Answer:

when x = 5; both expressions are equivalent and equal to 14

Step-by-step explanation:

We are told the expressions are:

(x + 4 + x) and (6 + 2x - 2).

We are also told that when x = 3,both expressions are equal and have a value of 10 each.

Now, when x = 5; we are told the expression (x + 4 + x) has a value of 14.

So when x = 5,let's find the value of the second expression by putting 5 for x in (6 + 2x - 2);

So, we have; 6 + 2(5) - 2 = 6 + 10 - 2 = 14

So when x = 5; both expressions are equivalent and equal to 14

Answer:

Correct option: C -> 2

Step-by-step explanation:

The first equation is:

[tex]x^2+y^2=363[/tex]

And the second equation is:

[tex]x-y+1=0[/tex]

From the second equation, we have:

[tex]y = x + 1[/tex]

Using this value of y in the first equation, we have:

[tex]x^2 + (x+1)^2 = 363[/tex]

[tex]x^2 + x^2 + 2x + 1 = 363[/tex]

[tex]2x^2 + 2x= 362[/tex]

[tex]x^2 + x - 181 = 0[/tex]

Calculating the discriminant Delta, we have:

[tex]\Delta = b^2 - 4ac = 1 + 4*181 = 725[/tex]

We have [tex]\Delta > 0[/tex], so we have two real values for x, therefore we have two solutions for this system.

Correct option: C.

(If the system of equation is actually:

[tex]x^2+y^2=36[/tex]

[tex]3x-y+1=0[/tex]

We would have:

[tex]y = 3x + 1[/tex]

[tex]x^2+(3x+1)^2=36[/tex]

[tex]x^2+9x^2+6x+1=36[/tex]

[tex]10x^2+6x-35=0[/tex]

[tex]\Delta = 36 + 1400 = 1436[/tex]

We also have [tex]\Delta > 0[/tex], so we have two solutions for this system.

Correct option: C.)
