The length of the shorter leg of a 30-60-90 Special Right Triangle is 17 yd long. How long is the longer leg of the triangle?
1) 17yd
2) 17√2yd
3) 17√3yd
4) 34yd
Answer:
[tex]17\sqrt{3}[/tex]
Quiz Results:
The length of the longer leg in the considered 30-60-90 Special Right Triangle is given by: Option 3) 17√3yd
What is a 30-60-90 Special Right Triangle?The right angled triangle in which, the angles are of the measure 30, 60 and 90 degrees is called 30-60-90 Special Right Triangle.
What is law of sines?For any triangle ABC, with side measures |BC| = a. |AC| = b. |AB| = c,
we have, by law of sines,
[tex]\dfrac{sin\angle A}{a} = \dfrac{sin\angle B}{b} = \dfrac{sin\angle C}{c}[/tex]
Remember that we took
[tex]\dfrac{\sin(angle)}{\text{length of the side opposite to that angle}}[/tex]
The wider the angle is, the larger the side opposite to is.
For this right angled triangle, the side opposite to 60 degrees angle is larger leg (let it be of x yd), and the side opposite to 30 degrees angle is shorter leg (of 17 yd).
As shown in the image below, using the sine law for non right angles, we get:
[tex]\dfrac{\sin\angle A}{a} = \dfrac{\sin\angle B}{b}\\\\\dfrac{\sin(30^\circ)}{17} = \dfrac{\sin(60^\circ)}{x}\\\\x =\dfrac{17 \times \sin(60^\circ)}{\sin(30^\circ)} = 17\sqrt{3} \: \rm yd[/tex]
Thus, the length of the longer leg in the considered 30-60-90 Special Right Triangle is given by: Option 3) 17√3yd

Answer:
Number of bags of chocolate chip cookies = x = 0.133 bags
Number of bags of walnuts = 7.7 bags
Step-by-step explanation:
Chocolate chip cookies = 12oz per bag = $3
Walnuts = 4oz per bag = $2
She need 3 pounds of Chocolate chip cookies and Walnuts
Let us represent
Number of bags of chocolate chip cookies = x
Number of bags of walnuts = y
She need 3 pounds of Chocolate chip cookies and Walnuts
Hence,
We have to convert oz (ounces) to pounds
For chocolate chip cookies
1 oz = 0.0625 pound
12 oz = x
Cross Multiply
x = 12 × 0.0625 pound
x = 0.75pound
For Walnuts
1 oz = 0.0625 pound
4 oz = x
Cross Multiply
x = 4 × 0.0625 pound
x = 0.25pound
Hence,
0.75 pound = $3
0.25 pounds = $2
She can only spend $15
Chocolate chip cookies = 12oz per bag = $3
Walnuts = 4oz per bag = $2
Hence,
0.75x + 0.25y = 3..... Equation 1
3x + 2y = 15.... Equation 2
Multiply Equation 1 by 2 and Equation 2 by 0.25
1.5x + 0.5y = 3... Equation 3
1.5x + 4y = 30.... Equation 4
Subtract Equation 3 from 4
3.5y = 27
y = 27/3.5
y = 7.7 bags
Solving for x using Equation 2
3x + 2y = 15.... Equation 2
3x + 2(7.7) = 15
3x + 15.4 = 15
3x = 0.4
x = 0.4/3
x = 0.133 bags
Number of bags of chocolate chip cookies = x = 0.133 bags
Number of bags of walnuts = 7.7 bags
Movers are filling the truck below with cube shaped boxes. If each box has edge lengths of 12 yard, how many total boxes will fit in the truck? L: 3 1/2 yds W: 5 yds H: 2 1/2 yds
Answer:
14boxes
Step-by-step explanation:
Given the following
Length of truck: 3 1/2 yds
Width of truck: 5 yds
Height of truck: 2 1/2 yds
Volume of truck = Length * Width * Height
Volume of truck = 3 1/2 * 5 * 2 1/2
Volume of truck = 7/2 * 5 * 5/2
Volume of truck = 7/4 cubic yards
For each box
Length L = 1/2 yd
Volume of each box = 1/2 * 1/2 * 1/2
Volume of each box = 1/8 cubic yds
Since 1 box = 1/8 cubic yds
x box = 7/4 cubic yds
Cross multiply
1/8x = 7/4
Cross multiply
4 * x = 7 * 8
4x = 56
x = 56/4
x = 14
Hence the total boxes that can fit in the trunk is 14boxes

Find the value of r in the figure.
Assume that lines a and bare parallel.
(4r - 30)
(2x)
b
Answer:
A) x = 15
Step-by-step explanation:
4x - 30 = 2x
subtract 2x from each side of the equation:
2x - 30 = 0
add 30 to each side:
2x = 30
x = 15
Answer:
[tex] \displaystyle A) {15}^{ \circ} [/tex]
Step-by-step explanation:
remember that,
when a transversal crosses two parallel lines then the Alternate interior angles are equal that is being said
[tex] \displaystyle 4x - 30 = 2x[/tex]
cancel 2x from both sides:
[tex] \displaystyle 2x - 30 = 0[/tex]
add 30° to both sides:
[tex] \displaystyle 2x = 30[/tex]
divide both sides by 2:
[tex] \displaystyle x =15[/tex]

Maribel pidio 100 refrescos a una tienda,los de naranja se los vendieron a $35.00 y los de cola a $38.00 si pago en total $3620 cuantos refrescos de naranja pideo
Answer:
the number of orange sodas be 60
Step-by-step explanation:
Let us assume the orange ones be x
And, the cola ones be y
Now according to the question
x + y = 100
y = 100 - x.........(1)
35x + 38y = $3,620........(2)
Now put the value of equation 1 in equation 2
So,
35x + 38(100- x) = 3620
35x + 3800 - 38x = 3620
-3x = -180
x = 60
Hence, the number of orange sodas be 60

Write an expression that represents the perimeter of a trapezoid with side lengths z+5,8z-10, 4z+9, and 3z-6
Answer:
Perimeter = (16z - 2)
Step-by-step explanation:
Perimeter of a polygon = sum of the lengths of all sides of the polygon
Sum of all sides of the trapezoid = (z + 5) + (8z - 10) + (4z + 9) + (3z - 6)
By adding like terms,
Perimeter of the trapezoid = ( z + 8z + 4z + 3z) + (5 - 10 + 9 - 6)
= 16z - 2
Therefore, expression representing the perimeter of the trapezoid will be,
(16z - 2)
The number of butterflies in an exhibit is decreasing at an exponential rate of decay. The number of butterflies is decreasing by 5% every year. There are 500 butterflies in the exhibit right now. How many butterflies will be in the exhibit in 7 years? Round your answer to a whole number.
Answer:
349 butterflies
Step-by-step explanation:
The formula for Exponential Decay =
y = a(1 - r)^t
Where y = Size of population after time t = ?
a = Initial size of population = 500
r = Decay rate = 5%
t = Time = 7 years
Hence,
y = 500(1 - 0.05)⁷
y = 500(0.95)⁷
y = 349.16864805 butterflies.
Approximately = 349 butterflies

Each base in this oblique prism is a right triangle.
What is the volume of the figure?
Answer:
66 cm³
Step-by-step explanation:
From the diagram,
Volume of the prism(v) = Area of the base (A)×Height(h)
v = A×h............... Equation 1
But,
A = bh/2.................... Equation 2
Where b = base of the triangle, h = height of the triangular base.
Substitute equation 2 into equation 1
v = (bh/2)H.................... Equation 3
Also for the diagram,
Given; b = 3 cm, h = 4 cm, H = 11 cm
Substitute these values into equation 3
v = (3×4×11)/2
v = 132/2
v = 66 cm³
Bill is a painter, who has been hired to paint a house.
• He receives an houry rate of $35 an hour.
• The materials Bill had to purchase cost $50 for the job.
• The amount of money Bill makes in profit, after working "x" hours, is modeled by the function:
f(x) = 352 – 50
Determine Bill's profit after working 10 hours.
Answer: 300
Step-by-step explanation: Math - 35X10-50
I may be wrong sorry!
Replace x with 10 in the given function.
We are seeking f(10).
f(10) = 35(10) - 50
f(10) = 350 - 50
f(10) = 300
After 10 hours, Bill's profit is $300.
