Wilhelm bought some shirts. He paid $12 for each shirt. This can be modeled by the expression 12x. what does x represent?

Answer:

x = 3, y = 30.4

Step-by-step explanation:

From the given diagram;

8x - 3 = 6x+3 (alternate exterior angle are equal)

Collect like terms

8x - 6x = 3 + 3

2x = 6

x = 6/2

x = 3

Also;

8x - 31 + 5y + 35 = 180 (sum of angle on a straight line is 180)

8(3) - 31 + 5y + 35 = 180

5y + 24 - 31 + 35  = 180

5y + 28 = 180

5Y = 180 - 28

5Y = 152

y = 152/5

y = 30.4

Hence x = 3, y = 30.4

Given:

A figure of a triangle.

To find:

The values of x and y.

Solution:

From the given triangle it is clear that the base angles of the triangle are equal, so the triangle is an isosceles triangle.

Altitude on the base of the isosceles triangle from from the opposite angle is a median. It means, it divides the base in two equal parts.

In the given triangle, the altitude divides the base in two equal parts and the measure of each part is 9 units.

In a right triangle,

[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos 60^circ=\dfrac{9}{y}[/tex]

[tex]\dfrac{1}{2}=\dfrac{9}{y}[/tex]

[tex]1\times y=9\times 2[/tex]

[tex]y=18[/tex]

And,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

[tex]\tan 60^\circ=\dfrac{x}{9}[/tex]

[tex]\sqrt{3}=\dfrac{x}{9}[/tex]

[tex]9\sqrt{3}=x[/tex]

Therefore, the correct option is D.

Answer:

D.

5555.55556

Step-by-step explanation:

a% over 100 and 50 over 90

Answer: $5

Step-by-step explanation:

We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.

Therefore, let the price of the socks be represented as x.

70% of x = 14

70/100 × x = 14

0.7 × x = 14

0.7x = 14

x = 14 / 0.7

x = 20

Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:

= $20 / 4

= $5

Answer:

sinA = 12/13, cosA = 5/13, tanA = 12/5

sinB = 5/13, cosB = 5/13, tanB = 5/12

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

Sin(A) = 12/13

Sin(B) = 5/13

Cos(A) = 5/13

Cos(B) = 12/13

Tan(A) = 12/5

Tan(B) = 5/12

Answer:

y=36degrees

Step-by-step explanation:

74+2y+34=180

2y+108=180

2y+108-108=180-108

2y=72

72/2

y=36degrees

Answer:

Step-by-step explanation:

Because these are supplementary angles they must have a sum of 180 degrees.

74+2y+34=180

2y+108=180

2y=72

y=36 degrees

Step-by-step explanation:

the exterior angle is equal to the sum of the opposite interior angles

-Sumin <3

Answer:

98

Step-by-step explanation:

53+45+x = 180

53+45=98

180-98=82

82 (interior)

82+98=180

x = 98

Answer:

502.85 feet

Step-by-step explanation:

Given that,

The radius of a Ferris wheel, r = 16 feet

We need to find how far will you travel if you take a ride that goes around 5 times.

Distance = 5×2πr

So,

= 10πr

[tex]=10\times \dfrac{22}{7}\times 16\\\\=502.85\ \text{feet}[/tex]

So, the required distance is 502.85 feet.

9514 1404 393

Answer:

Step-by-step explanation:

A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).

Here, we have ...

  h = -16t^2 +44t +5

  t = -44/(2(-16)) = 11/8 = 1.375

It takes 1.375 seconds for the ball to reach its maximum height.

The height at that time is ...

  h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25

The maximum height is 35.25 feet.

Answer:

5.73 years

Step-by-step explanation:

Considering she saved 4.25% in each year of the amount $15000.

So, we have to calculate in what time her saving reaches $1275, if she save each year.

it becomes question of simple interest in which

SI = $1275, Principal P= $5000, time T, rate R = 4.25%

we know SI = PRT/100

1275 = 5000×4.25×T/100

⇒T = 1275×100/(5000×4.25)

⇒ T= 5.73 years

Answer:

y = 1

They will pass through each other perpendicular, also you can look up graph in chrome and use a free graph.

Step-by-step explanation:

The equation of the line perpendicular to the graph of x = -7 and which passes through the point (-7,1) is y=1.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

As the equation x=-7 will represent a straight verticle line at x=-7. Therefore, the line that will perpendicular to this line will be a horizontal line. Since it is given that the line must intersect at (-7,1). The horizontal line should be at y=1.

Hence, the equation of the line perpendicular to the graph of x = -7 and which passes through the point (-7,1) is y=1.
