Answer:
5/13
Step-by-step explanation:
1. We are given tan(x)=5/12 .....(2)
2. On comparing the quantities we get that p=5 and b=12
3. We require the value of hypotenuse(h),
for this we apply the Pythagoreum theorum: p^2+b^2=h^2
⇒h^2=5^2+12^2
⇒h^2=25+144
⇒h^2=169
⇒ h=√169
⇒ h=13
Sin=p/h
p=5
h=13
Sin=5/13

Brandon is rolling two six-sided dice. What is the probability that one die lands on an even number and the other die lands on an odd number?
Answers
Answer:
50-50 on both because there 3 even and 3 odd numbers
Answer:
50% chance of either or 1/2
Step-by-step explanation:
50% of either
Look a die has 12 sides
6 numbers are odd and the other 6 even
If you randomly roll a die you will have 6/12 chances of landing on a even number and a 6/12 chance of landing on a odd number
now 6/12 can be simplified to 1/2 which is 50%
Hope that helps!

What is the equation of the line that passes through the point (−0.5,8) and has a slope of −5?
Answers
Answer:
Slope=-1.8, X=-0.5, y=1.9
Equation is y^2-y^1=m(x^2-x^1).
Y-1.9=-1.8(X-(-0.5))
Y-1.9=-1.8x+0.90
Add 1.9 on both sides.
Y= -1.8x+1.

What is the area of the figure? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answers
Answer:
81.12 cm²
Step-by-step explanation:
The area for a semicircle can be figured with this formula: (πr²)/2. The triangle's area formula is bh/2.
(3.14 * 4²)/2 + (14 * 8)/2 (Work the operations in parentheses first.)
(3.14 * 16)/2 + 112/2
50.24/2 + 112/2 (Divide 50.24 by 2. Do the same for 112.)
25.12 + 56 (Add 25.12 & 56.)
81.12 cm²
The area of the figure is 81.12 cm².

Answer:
Area = 346.2yd²
Perimeter = 72.1yd
Step-by-step explanation:
AREA
Split it into three shapes: (1) the semi-circle, (2) the triangle, and (3) the rectangle. Find the area of each and then add them together for the area of the whole shape.
Area₁ = πr² = (6²)π = 36π = 113.1 yd²
Area₂ = (1/2)bh = (1/2)(11.3)(14) = 79.1 yd²
Area₃ = lw = (11)(14) = 154 yd²
154 + 79.1 + 113.1=346.2yd²
PERIMETER
The perimeter consists of the length of the curve on the semi-circle, the top , the right side, the bottom, and the slanted line.
length of the curve on the semi-circle = half the cicumference of circle with radius 6 = (2π(6))/2 = 6π = 18.8
the top = 22.3
the right side = 14
the bottom = 11
the slanted line = the hypotenuse of triangle(2) - the diameter of circle(1) = (√(11.3²+14²))-12= (√(323.69))-12=18-12=6
18.8+22.3+14+11+6=72.1yd

You decide that you want new carpeting in your bedroom that measures 12 feet 6 inches wide by 15 feet 9 inches long. The price of the carpet and the underlying pad is $3.49 per square foot. You decide to upgrade to the deluxe underlying pad that costs an additional $0.62 per square foot. The fee for installation is a flat fee of $180. What is the total cost, including sales tax of 6.7%, of the carpet, pad, and installation? Round your answer to the nearest cent. Write the equation that represents the total cost.
Answers
Answer:
The total cost of the new carpeting is $ 1,055.43.
Step-by-step explanation:
Since I decide that I want new carpeting in my bedroom that measures 12 feet 6 inches wide by 15 feet 9 inches long, and the price of the carpet and the underlying pad is $ 3.49 per square foot, and I decide to upgrade to the deluxe underlying pad that costs an additional $ 0.62 per square foot, and the fee for installation is a flat fee of $ 180, to determine what is the total cost, including sales tax of 6.7%, of the carpet, pad, and installation, the following calculations must be performed:
1 inch = 0.08333 feet
6 inches = 0.08333 x 6 = 0.5
9 inches = 0.08333 x 9 = 0.75
12.5 x 15.75 = Bedroom area
196,875 square feet = Bedroom area
((196.875 x (3.49 + 0.62)) + 180) x 1.067 = Total cost
((196,875 x 4.11) + 180) x 1,067 = Total cost
(809.15625 + 180) x 1.067 = Total cost
989.15625 x 1.067 = Total cost
1,055,429 = Total cost
Therefore, the total cost of the new carpeting is $ 1,055.43.
