how long should the ladder be if they want to use all the canle they have? use the law of sines to find the length.
Answer: L = 36 feet approximately
The more accurate value is 35.9547644 feet, but this approximate value isn't exact either.
============================================================
Explanation:
Ignore the vertical line and any byproducts of it.
Refer to the diagram below. Note that the 95 degree angle is from 15+80 = 95.
We can use the law of sines like so
sin(A)/a = sin(B)/b
sin(75)/200 = sin(10)/L
L*sin(75) = 200*sin(10)
L = 200*sin(10)/sin(75)
L = 35.9547644 which is approximate.
This rounds to roughly 36 feet when rounding to the nearest whole number.
Side note: We never use angle C = 95, and its opposite side.
A rectangular bathroom mirror has a perimeter of 22 feet. Its area is 18 square feet. What are the dimensions of the mirror?
Answer:
The dimensions of the mirror is 9 feet and 2 feet
Step-by-step explanation:
Keep in mind that the area and perimeter of a rectangle is:
Area - length x width
Perimeter - 2 (l + w)
List the factors of 18 (the area of the mirror):
1, 2, 3, 6, 9, 18
POSSIBLE DIMENSIONS OF MIRROR:
1 ft and 18 ft
Area = 18 ft^2
Perimeter = 38 feet
2 ft and 9 ft
Area = 18 ft^2
Perimeter = 22 feet
3 ft and 6 ft
Perimeter = 18 feet
The rectangle with dimensions 2 feet and 9 feet corresponds with the area and perimeter of the mirror mentioned. So those are the correct dimensions.
Hope these helps!
Prove hat the ditance between any two points inside triangle ABC is not greater than half the perimeter of ABC
Answer:
It is not because the half the perimeter is not only one side but another half side of the triangle, and the distence between two points in a triangle can never become longer then the length of one side.

Consider the formula 4(h-3k)= h+7.
(a) Make k the subject of the above formula.
(b) If the value of h is decreased by 8, write down the change in the value of k.
guys I really need help
plzzzzzz
Answer:
=k=0.25h-7/12
Step-by-step explanation:
4(h-3k)=h+7
=4h-12k=h+7
collecting like terms and leaving characters with k on 1 side, we get;
12k=3h-7
=k=0.25h-7/12

Graph the line that passes through the points (-5,1) and (5, -5) and determine the equation of the line.
Answer:
y = -3/5x - 2
Step-by-step explanation:
y2 - y1 / x2 - x1
-5 - 1 / 5 - (-5)
-6/ 10
= -3/5
y = -3/5x + b
1 = -3/5(-5) + b
1 = 3 + b
-2 = b

Answer:
8 lb box
Step-by-step explanation:
Find which laundry detergent has a lower unit price
The unit price is how much something costs for a single unit
In this case, it is how much the detergent costs for 1 pound
7.4/8 lbs = 0.925 dollars per lb
5.38/4 lbs = 1.345 dollars per lb
Since 1.345 > 0.925, the 8 lb box is a better buy
Case 1
Cost of 8 pound detergent = $7.40
So, cost of 1 pound detergent
= $7.40 ÷ 8
= $0.925
Case 2
Cost of 8 pound detergent = $5.38
So, cost of 1 pound detergent
= $5.38 ÷ 4
= $1.345
$0.925 < $1.345
$0.925 < $1.345So, cost per pound in 8 pound box < cost per pound in 4 pound box
So, buying the 8 pound box is better.
there were 54 marbles in total the ratio of green to blue is 7:2 work out the number of green marbles
Answer:
42 green marbles
Step-by-step explanation:
sum the parts of the ratio, 7 + 2 = 9 parts
Divide the number of marbles by 9 to find the value of one part of the ratio.
54 ÷ 9 = 6 ← value of 1 part of the ratio , then
7 parts = 7 × 6 = 42 ← number of green marbles
three numbers are in the ratio 1:2:1 find the largest number if the sum of their cubes is 1000
Answer:
Given,
The ratio of the three numbers are 1:2:3 . Let the numbers are x , 2x and 3x.
According to the question,
x³+(2x)³+(3x)³=4,500
⟹x³+8x³+27x³=4,500
⟹36x³=4500
⟹x³=4,50036
⟹x³=125
⟹x=125−−−√3
⟹x=5
So the numbers are 5,5×2=10,5×3=15
Therefore, 5 is the smallest number.

Hi there!
[tex]\large\boxed{m = 2}[/tex]
Since the line is increasing (the y-values are increasing as x increases), we can automatically eliminate any answer choice containing a negative slope.
Thus, the only correct answer choice would be m = 2.
We could also solve using the slope formula:
m = y2-y1/x2-x1
Plug in given points:
m = 3-1 / 0 - (-1)
m = 2 / 1 = 2
Select the correct answer.
The function g(x) = x2 is transformed to obtain function h:
h(x) = g(x − 3).
Which statement describes how the graph of h is different from the graph of g?
A.
The graph of h is the graph of g vertically shifted up 3 units.
B.
The graph of h is the graph of g horizontally shifted right 3 units.
C.
The graph of h is the graph of g horizontally shifted left 3 units.
D.
The graph of h is the graph of g vertically shifted down 3 units.
Answer:
B
Step-by-step explanation:
Given g(x) then g(x + a) is a horizontal translation of g(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
h(x) = g(x - 3) = (x - 3)² with a < 0
The graph of h(x) is the graph of g(x) horizontally shifted right 3 units
The table shows the relationship between the number of white shells and the number of pink beads that Aliz uses to decorate 6 different
jewelry box. Which of the following equations relates the number of pink beads, p, to the number of white shells, w? �� p = 25w �� w = 52p �� 5w = 2p �� p = 52w
Answer:
p = 5/2w
Step-by-step explanation:
We want the ratio of pink beads to white shells
p: w
5: 2
Cross multiply
2p = 5w
Divide by 2
p = 5/2w

Simplify [tex]x^{2} - 36[/tex]
Answer:
[tex] {x}^{2} - 36 \\ = (x + 6)(x - 6)[/tex]
Step-by-step explanation:
x^2-36
(x+6) ( x-6)
it's helpful to you
Answer:
[tex](x-6)(x+6)[/tex]
Step-by-step explanation:
In order to simplify this equation, one must use the quadratic factoring patterns. These patterns are as follows:
[tex]a^2-b^2=(a-b)(a+b)[/tex]
This pattern works because, if one is to distribute the terms in the parenthesis by multiplying each term in one of the parenthesis by every term in the other, the result is the original equation:
[tex](a-b)(a+b)\\\\=(a)(a)+(a)(-b)+(a)(b)+(b)(-b)\\\\=a^2-ab+ab-b^2\\\\=a^2-b^2[/tex]
One can apply this pattern to the given equation, remember (6) times itself equals (36). Therefore, one can state the following: ([tex]36=6^2[/tex]), thus one can apply it to the given equation:
[tex]x^2-36\\\\=x^2-6^2\\\\=(x-6)(x+6)[/tex]
