Step-by-step explanation:
1) if sin(ACB)=BC/BD, then BC=BD*sin(ACB);
2) m(ACB)=60°, then sin(ACB)=√3/2, then
3) BC=5/(√3/2)=10/√3 or 10√3/3.

It takes 4 people 6 days to build a wall. How long would it take 6 people to build the same wall?
Answers
Answer:
1 day
Step-by-step explanation:
4=6
2=3
2*3=6
so 3/3=1
It would take 6 people to build the wall 1 day
It takes 4 days to build the same wall with 6 people based on the given ratio.
What are the ratio and proportion?The ratio is the division of the two numbers.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
It takes 4 people 6 days to build a wall.
The number of people days taken = 4 x 6 = 24 people takes
This means if one person wants to build them it takes 24 days.
For 6 people the time taken will be 24/6 = 4 days.
Hence "It takes 4 days to build the same wall with 6 people based on the given ratio".

In 2014, the average price of a new car was $37,600. For the period shown, new-car prices increased by approximately $1250 per year. If this trend continues, how many years after 2014 will the price of a new car average $46,350? In which year will this occur?
Answers
The year in which the average price of a new car would average $46,350 is 2021.
In which year would the price of a new car average $46,350?The price of a new car increases by $1250 per year. This is known as appreciation. The value of a new car can be represented with this equation:
Value of new car = value of the car now + (rate of increase x number of years)
Number of years = value of the new car - value of the car now) / rate of increase
(46350 - 37600) / 1250 = 7 years
7 + 2014 = 2021

Step-by-step explanation:
Let the probability of getting a multiple of 3 is "A"
Let the probability of getting an even number is "B"
Total number of outcomes=36
Total number of favourable outcomes of either a multiple of 3 or an even number are
(1,1) ,(1,2) ,(2,1) ,(1,3) ,(3,1) ,(2,2) ,(1,5) (5,1) ,(3,3) ,(2,4) ,(4,2) ,(2,6) ,(6,2) ,(3,5) ,(5,3) ,(4,4) ,(6,4) ,(4,6) ,(5,5) ,(6,6)
That is we have 20 favourable outcomes
Hence, Probability=\frac{\text{favourable outcomes}}{\text{total number of outcomes}}Probability=
total number of outcomes
favourable outcomes
Therefore, after substituting the values we get
probability=\frac{20}{36}probability=

20
After simplification we will get

During a basketball game a player makes 12 of 18 free throws attempted. Write the ratio as a fraction reduced to lowest terms

[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
12 out of 18 free throws is also equal to the fraction [tex]\frac{12}{18}[/tex]. To simplify this fraction, we have to find out the greatest common factor (GCF) of 12 and 18. It turns out that the GCF of 12 and 18 is 6. So, we have to divide the fraction by 6 to reduce it to its lowest terms.

The length and breadth of a rectangular piece of paper are 18 cm and 15 cm respectively. By how much should be length be reduced keeping breadth constant to make area equal to 134 cm².....
Answers
Answer:
Area of a rectangle = length x breadth
Given:
area = 134 cm²breadth = 15 cm⇒ 134 cm² = length x 15cm
⇒ length = 134 ÷ 15
= 8.93333333... cm
Reduction in length = original length - new length
= 18 cm - 8.93333333... cm
= 9.07 cm (nearest hundredth)

A triangle is always determined by the names of its angles. If, for any reason, you wanted to label it by its side names(which I don't even think you can do but assuming you wanted to), you dont even have the names for all three sides here. So, it can only be d. A, X, and T are the three angle names for this triangle, so this is triangle ATX or AXT.
Answer:
ATX (option d)
Step-by-step explanation:
Sides of any polygon are called as vertices.
Vertices of the triangle or endpoints of the sides of the polygon are A, T and X.

Find the surface area of the cone in terms of π.
Answers
Answer:
161 × pi cm²
Step-by-step explanation:
we just had the question about the lateral surface area (which is the area of the "mantle" of the cone from the round bottom to the pointy top).
the whole surface area of a cone is then simply the lateral surface area plus the ground area, which is a circle.
so, we have
A = pi×r×sh + pi×r²
r = radius (remember, this is half of the diameter)
sh = slant height (the length of the "mantle" straight up from the ground to the top)
so, the surface area of our cone here is
A = pi×(14/2)×16 + pi×(14/2)² = pi×7×16 + pi×7² =
= 112×pi + 49×pi = 161 × pi cm²
