Step-by-step explanation:
Using Trignometry,
sin60° = BC/10.
=> BC = 10sin60°
= 10 * (√3/2) = 5√3 = 8.7. (1d.p.)
Answer:
[tex] \sin(60°) = \frac{BC}{10} \\ \frac{ \sqrt{3} }{2} = \frac{BC}{10} \\ BC = \frac{10 \sqrt{3} }{2} \\ BC= 5 \sqrt{3}\\\boxed{\red{BC= 8.7}}[/tex]
8.7 is the right answer.Related Questions

Answer:
We conclude that the price per pound of the grapes = $1.45
Hence, option A is true.
Step-by-step explanation:
Given the table
Pounds of Grapes Total Cost
1.2 $1.74
2.6 $3.77
4.4 $6.38
Total pounds of Grapes = 1.2+2.6+4.4
= 8.2 pounds
Aggregate cost = 1.74 + 3.77 + 6.38
= $11.89
Thus,
Prince per pound = Aggregate cost / Total pounds of Grapes
= 11.89 / 8.2
= $1.45
Therefore, we conclude that the price per pound of the grapes = $1.45
Hence, option A is true.

Answer:
9.22
Step-by-step explanation:
The distance formula is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using the given coordinates, the distance between them is ...
d = √((8-(-1))^2 +(0 -(-2))^2) = √(9^2 +2^2) = √85 ≈ 9.22
The length of AB is about 9.22 units.

A circle has a diameter of 18 feet. Which following is closest to the l circumference of the circle?
A-28.3ft
B-56.5ft
C-113.1ft
D-245.5ft
Answers
circumference =2×pi×r
18/2=9(r)
so...2×pi×9
=54..5
Answer:
56.5 ft
Step-by-step explanation:
We define the number π as the ratio between the circumference and diameter of a circle: π = c/d. Rearranging this equation gives us one for the circumference: c = πd. Using an approximation of π ≈ 3.14 and our value of d = 18 feet, we can find that c = 3.14(18) = 56.52 ft, or 56.5 ft, rounded to the nearest tenth.

A flower bed is in the shape of a triangle, with a base of 13 feet and a height of 5 feet. What is the area of the flower bed?
1. 18 square feet
2. 32.5 square feet
3. 65 square feet
4. 130.5 square feet
Answers
Answer:
32.5
Step-by-step explanation:
For triangles you need to do base times height divided by 2
Answer:
Number 2: 32.5 square feet
Step-by-step explanation:
The formula for the area of a triangle is 1/2(base)(height)
In this case, our base is 13 ft and our height is 5 ft so we plug in those values into our formula
A = 1/2(13)(5) = 32.5
Therefore our area is 32.5 square feet.
The supreme choice pizza at Maria's Pizza Palace contains 2 different meats and 4 different vegetables. The customer can select any one of 5 types of crust. If there are 4 meats and 7 vegetables to choose from, how many different supreme choice pizzas can be made
Answers
Answer: Number of different supreme choice pizzas that can be made is 1050
Step-by-step explanation:
Given the data in the question;
Number of ways in which crust can be selected = 5
Number of ways in which 2 meats can be selected from 4 = ⁴C₂
⇒ 4! / ( 2! x (4-2)! )
= 6
Number of ways in which 4 vegetables can be selected from 7 = ⁷C₄
⇒ 7! / ( 4! x (7-4)! )
= 35
so; Number of different supreme choice pizzas that can be made;
⇒ 5 × 6 × 35
= 1050
Therefore, Number of different supreme choice pizzas that can be made is 1050

Which correlation coefficient represents a weak, positive linear relationship?
Select one:
a. r = 0
b. r = 0.35
c. r = −0.35
d. r = 0.94
e. r = −0.94
Answers
Step-by-step explanation:
The Correlation Coefficient
When the r value is closer to +1 or -1, it indicates that there is a stronger linear relationship between the two variables. A correlation of -0.97 is a strong negative correlation while a correlation of 0.10 would be a weak positive correlation.
Solve the following system of equations using substitution or elimination: y = −8x − 9 y = −6x + 5
Answers
Answer:
x = -7
y = 47
Step-by-step explanation:
Given the system of equation
y = −8x − 9 ... 1
y = −6x + 5 ...2
Equating both expressions
-8x - 9 = -6x + 5
Collect like terms
-8x + 6x = 5 + 9
-2x = 14
x = 14/-2
x = -7
Substitute x = -7 into equation 1.
From 1: y = −8x − 9
y = -8(-7) - 9
y = 56 - 9
y = 47
Hence the solution to the system of equations (x, y) is (-7, 47)
