Answer:
[tex]k=\dfrac{5}{9}[/tex]
Step-by-step explanation:
The given equation is :
[tex]y=\dfrac{5}{9}x[/tex] ...(1)
We need to find the constant of proportionality in the equation.
In this equation, y is directly proportional to x i.e.
y ∝ x
or
y = kx ...(2)
k is constant of proportionality
If we compare equation (1) and (2), we find that,
[tex]k=\dfrac{5}{9}[/tex]
So, the constant of proportionality is equal to [tex]\dfrac{5}{9}[/tex].

A kite has a 50 foot long string. If the angle of elevation to the kite measures 60 degrees, how high is the kite above the ground? Round to the nearest tenth. Pleaseee help!!!!
Answer:
Step-by-step explanation:
Draw a picture. You have a 30-60-90 triangle, so the sides are in the ratio 1:√3:2.
The string of the kite is the side opposite the 90° angle. The side opposite the 30° angle is 25 ft.
The vertical leg of the triangle is 25√3 ≈ 43.3 ft

What is the distance between 4 and 17?
Answer:
14
Step-by-step explanation:
17 - 4 + 1 = 13 + 1 = 14
Answer:
Step-by-step explanation:
D = distance
[tex]x_{1}[/tex] = 4
[tex]x_{2}[/tex] = 17
No "y" values were given.
The distance formula:
[tex]D=\sqrt{(x_{1} - x_{2} )^{2} +(y_{1} - y_{2} )^{2}}[/tex]
If we insert in the values:
[tex]D = \sqrt{ (4 - 17)^{2} + (0 - 0)^{2}}[/tex]
(0-0)^2 = 0 so we can just remove the last part since it's +0:
[tex]D = \sqrt{(4 - 17)^{2}}[/tex]
4 - 17 is equal to -13:
[tex]D = \sqrt{(-13)^{2}}[/tex]
Since [tex](-a)^{2} = (a)^{2}[/tex], that means that the negative 13 becomes positive
[tex]D = \sqrt{(13)^{2}}[/tex]
Now the square root and the square cancels each other out:
[tex]D = 13[/tex]

ABCD- parallelogram, If the perimeter of Triangle CPQ is 15cm, Find the perimeter of triangle BAQ. Find the perimeter of triangle PDA. PLEASE FIND THE ANSWER QUICKLY I NEED IT RIGHT NOW
Answer:
The answer is below
Step-by-step explanation:
A parallelogram is a quadrilateral (has 4 sides and 4 angle) with two pair of parallel and opposite sides. Opposite sides of a parallelogram are parallel and equal.
Given parallelogram ABCD:
AB = CD = 18 cm; BC = AD = 8 cm
∠P = ∠P, ∠PDA = ∠PCQ (corresponding angles are equal).
Hence ΔPCQ and ΔPDA are similar by angle-angle similarity theorem. For similar triangles, the ratio of their corresponding sides equal. Therefore:
[tex]\frac{CD}{PC}= \frac{AD}{CQ}\\\\\frac{18}{6}=\frac{8}{x} \\\\x=\frac{6*8}{18}=\frac{8}{3}\ cm[/tex]
Perimeter of CPQ = CP + CQ + PQ
15 = 6 + 8/3 + PQ
PQ = 15 - (6 + 8/3)
PQ = 6.33
∠CQP = ∠AQB (vertical angles), ∠QCP = ∠QBA (alternate angles are equal).
Hence ΔCPQ and ΔABQ are similar by angle-angle similarity theorem
[tex]\frac{AQ}{QP}=\frac{AB}{CP} \\\\\frac{AQ}{6.33} =\frac{18}{6} \\\\AQ=\frac{18}{6}*6.33\\\\AQ = 19[/tex]
[tex]\frac{BQ}{CQ}=\frac{AB}{CP} \\\\\frac{BQ}{8/3} =\frac{18}{6} \\\\BQ=\frac{18}{6}*\frac{8}{3} \\\\BQ =8[/tex]
Perimeter of BAQ = AB + BQ + AQ = 18 + 8 + 19 = 45cm
PA = AQ + PQ = 19 + 6.33 = 25.33
PD = CD + DP = 18 + 6 = 24
Perimeter of PDA = PA + PD + AD = 24 + 25.33 + 8 = 57.33 cm
What is the answer to -180=-10v+10
Answer:
Step-by-step explanation:
-180=-10v+10
-190=-10v
v=19
Answer:
19
Step-by-step explanation:
[tex]-180=-10v+10[/tex]
subtract 10 from both sides
[tex]-190=-10v[/tex]
divide both sides by 10
[tex]v=19[/tex]

A shop sells two different bags of rice.
Rice A
500g plus 25% extra free
Rice B
750g plus 1/5 extra free
Which bag gives you more free rice.
Show your working.
Answer: rice a
Step-by-step explanation:
convert 1/5 to a decimal .20 <.25
Bag of rice B gives more rice than bag A as per the percentage.
What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" are also used, the percent symbol, "%," is frequently used to indicate it. A % is a number without dimensions and without a standard measurement.
Given, A shop sells two different bags of rice. Rice A has 500g plus 25% extra free and Rice B has750g plus 1/5 extra free.
For calculating the free amount of rice,
For Bag A
Frre amount of rice = 500* 25% = 500 *25/ 100 = 125g
For Bag B
Frre amount of rice = 750 * 1/5 = 150g
Therefore, According to the percentage, bag B of rice contains more rice than bag A.

What is meant by Trigonometric Identities?Trigonometric Identities are equality conditions that hold for all possible values of the variables in the equation and use trigonometry functions. There exists numerous unique trigonometric identities that relate a triangle's side length and angle.
Sine, cosine, and tangent are the fundamental three operations in trigonometry. The cotangent, secant, and cosecant functions are derived from these three basic functions. On these functions, all trigonometrical notions exists built.
Trigonometric identities are equality conditions in trigonometry that hold for all values of the variables that appear and are defined on both sides of the equivalence. These exists identities that, geometrically speaking, involve certain functions of one or more angles.

A university's freshman class has 7700 students. 67% of those students are majoring in Engineering. How many students in the freshman class are Engineering majors?
Answer:
5159 students
Step-by-step explanation:
To find a percentage of a number larger than 100, divide the percent by 100, so 67/100=0.67. Multiply that number by the number that you want to take the percentage of. 0.67 x 7,700 = 5,519

An alligator is 9 inches long at birth and grows 10 inches per year. Write an equation that represents the length y (in feet) of an alligator that is x years old. How long will the alligator be after 4 years?
Answer:
y=10x+9
after 4 years the gator will be 49 in long
Step-by-step explanation:
Answer:
y = 5/6x + 3/4.
At 4 years old, the length y = 49/12 feet = 4 feet 1 inch.
Step-by-step explanation:
9 inches = 3/4 feet.
10 inches = 5/6 feet
So our equations is
y = 5/6x + 3/4.
When it is 4 years old:
y = 5/6(4) + 3/4
= 20/6 + 3/4
= 49/12 feet

Since the opposite angles of a parallelogram are equal so...b=48
we also know that the sum of the interior angles of a parallelogram=360°

What is the value of x2+9x+20 when x could be -5, -3 or -6
Answer:
Step-by-step explanation:
You should use a ^ to indicate an exponent. x^2 is the same as x².
x² + 9x + 20
Replace the x with (-5).
(-5)² + 9(-5) + 20 = 25-45+20 = 0
Then do the same with x = (-3):
(-3)² + 9(-3) + 20 = 9 - 27 + 20 = 2
You can do x = (-6)
