Find the length of side BC.
Give your answer to 3 significant figures.
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )

What is the surface area? how did you find it(filled-in formula)?
Answer: 1719.22 mi squared
Step-by-step explanation:
you have to find the height first.
you only have r and hypotenuse
so
a^2 + b^2 = c^2
13^2 + b^2 = 29.1^2
169 + b^2 = 846.81
b^2 = 846.81 - 169
b^2 = 677.81
b = 26.03
height = 26.03
surface area formula :
_______
πr(r+_/h^2+r^2)
___________
π(13) [13 + _/26.03^2 + 13^2]
= 1719.22

Sofia misses 10% of the free throws she attempts in a season. How many total free
throws did she attempt if she missed 9?
Answer:
90
Step-by-step explanation:
0.1x=9
x=90
Answer:
90 free throws
Step-by-step explanation:
She would have attempted 90 free throws because since 9 is 10%, and 10x10 is 100, then you would just multiply 9x10.

help a girl out What is the slope of a line that would be perpendicular to line k?
Answer:
( -2 , -2 ) or ( 2 , 4 )
Step-by-step explanation:
Answer:
4-1/2-0 = 3/2
Step-by-step explanation:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
How would I find this? Would I do 90-40 and then get 50 or would I have to do 90-50 to get x?
Answer:
i think u have to use subtraction
Answer:
x = 50
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
subtract the sum of the 2 given angles from 180 for x
x = 180 - (90 + 40) = 180 - 130 = 50

Answer:
$29.14
$86.68
Step-by-step explanation:
$30 before tax
Discount: 20%
100% - 20% = 80% = 0.8
0.8 * $30 = $24 after discount
Tax: 6.4%
100% + 6.4% = 106.4% = 1.064
1.604 * $24 = 25.54 after tax and discount
Tip: 15% = 0.15
0.15 * $24 = $3.60
Total = $25.54 + $3.60 = $29.14
$75 before tax
10% discount
100% - 10% = 90%
90% of $75 = 0.9 * $75 = $67.50 after discount
Tax: 7%
100% + 7% = 107% = 1.07
1.07 * $67.5 = $72.23 after discount and tax
Tip: 20% = 0.2
0.2 * $67.50 = $13.50
Total = $72.23 + $13.50 = $85.73

The price, P, of a sweater was discounted by 10% in
February. Because the sweater did not sell by the end of
the winter season, it was discounted by another 20% in
March. In terms of P, what was the price of the sweater
after the discount in March?
Answer:
In terms of P, the price of the sweater after the discount is 0.72P.
Step-by-step explanation:
Since the price P would represent 100% and the price was discounted by 10%, you can calculate 10% of 100% and subtract that amount, which would be:
100*10%=10
100-10=90%
This means that the price paid would be 90% of P. Then, the statement says that the price was discounted by another 20%. So, you have to calculate 20% of the price and subtract that amount from the price:
90*20%=18
90-18=72%
According to this, this means that in terms of P, the price of the sweater after the discount is 0.72P.
The contractor for a new school put a rectangular garden in the courtyard. The length of this garden is 5 feet longer than its width. If this area is 414 square feet, what is the length of the rectangle?
Answer:
23ft
Step-by-step explanation:
Area of the rectangle = LW
L is the length
W is the width
Given
Area = 414ft²
If the length of this garden is 5 feet longer than its width, then;
L = W+5
Substitute into the formula
414 = (W+5)W
414 = W²+5W
W²+5W-414 = 0
W = -5±√5²-4(-414)/2
W = -5±√25+1656/2
W = -5±√1681/2
W = -5+41/2
W = 36/2
W = 18ft
Since L = W+5
L = 18+5
L = 23ft
Hence the length of the rectangle is 23ft

In a certain year, the average e-mail user sent or received 111 e-mails each day. The number of e-mails received was 3 more than twice the number
sent. How many were sent and how many were received each day?
Answer:
Number of sent mail = 36
Number of received mail = 75
Step-by-step explanation:
Let,
x be the number of mails sent
y be the number of mails received
According to given statement;
x + y = 111 Eqn 1
y = 2x + 3 Eqn 2
Putting value of y from Eqn 2 in Eqn 1
x + 2x + 3 = 111
3x = 111 - 3
3x = 108
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{108}{3}\\x = 36[/tex]
Putting x = 36 in Eqn 2
y = 2(36) + 3
y = 72 + 3 = 75
Hence,
Number of sent mail = 36
Number of received mail = 75
