Answer:the original height of the candle is 14.8 inches
Step-by-step explanation:A Candlestick burns at a rate of 0.2 inches per hour. It means that the height of the candle is decreasing by 2 inches per hour. This decrease is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed asTn = a + (n - 1)dWhere a represents the first term of the sequence.d represents the common difference.n represents the number of terms in the sequence.From the information given,d = - 0.2 (it is decreasing)n = 8T8 = 13.4 inchesWe want to determine the value of the first term, a. Therefore,13.4 = a - 0.2(8 - 1)13.4 = a - 1.4a = 13.4 + 1.4 = 14.8 inches

Find the missing variable. 3k+4(-k+2)=14k-22
Answer:
k=2
Step-by-step explanation:
Expanding gives
[tex]3k-4k+8=14k-22[/tex].
Further simplification yields
[tex]-k+8=14k-22[/tex]
[tex]15k=30[/tex]
[tex]k=2[/tex].
Step-by-step explanation:
Use the Distributive Property:
[tex]3k - 4k + 8 = 14k - 22[/tex]
[tex] - k + 8 = 14k - 22[/tex]
Add k to both sides:
[tex]8 = 15k - 22[/tex]
Add 22 to both sides:
[tex]30 = 15k[/tex]
Divide each side by 15:
[tex]2 = k[/tex]

If Krista wants the pen to be four times the area it is now
(5 feet long by 4 1/2 feet wide), what are two ways she could change
the length and/or width to give her that new area?
What would the new area be?
The two ways she could change the length and/or width are;
Multiply the length by a factor of 4 while leaving the width constantMultiply the width by a factor of 4 while leaving the length constantThe new area of the pen would be; 90ft²
Area of a penThe dimension of the pen given is;
5 feet long by 4 1/2 feet wideHence, the initial area of the pen is;
5 × 4.5 = 22.5 ft².Hence, to make the pen four times it's present area; Krista may multiply either of the length or width by a factor of 4.
And hence, the new area is; 22.5 × 4 = 90ft²

9) The length of the shorter leg of a 30° -60° - 90° triangle is 24 meters. Find the length of the hypotenuse.
Answer:
48 meters
Step-by-step explanation:
Shorter leg will be the side opposite to the angle measuring 30°. Using sin trigonometric ratio the length of hypotenuse can easily be obtained.
[tex] \sin 30 \degree = \frac{length \: of \: shorter \: leg}{length \: of \: hypotenuse} \\ \\ \implies \: \frac{1}{2} = \frac{24}{l(hypotenuse)} \\ \\ \implies \: {l(hypotenuse)} =2 \times 24 \\ \\ \implies \: {l(hypotenuse)} =48 \: m[/tex]

Answer:
(a) AA Similarity using alternate interior angles
(b) 6.3
Step-by-step explanation:
(a)
Triangles ABD and BDC have a given pair of congruent angles, angles ABD and BCD.
With parallel lines AB and DC and transversal BD, then alternate interior angles ABD and BDC are congruent.
Now we have two pairs of congruent corresponding angles, so by AA Similarity, triangles ABD and BDC are similar.
(b)
Triangles ABD and BDC are similar.
The ratios of the lengths of corresponding sides are equal.
AB/BD = AD/BC
4/6 = 4.2/BC
4BC = 6 × 4.2
BC = 6.3

Find the area of the triangle then round the answer to the nearest tenth (please help!!!)
Answer:
A = 2298.48
Step-by-step explanation:
The right triangle with the 35angle. you need to find the height of that triangle which is the adjacent side and the opposite side is 44
tan 35° = opposite/ adjacent
[tex]tan 35 = \frac{44}{x}[/tex]
[tex]tan 35(x) = 44[/tex]
[tex]x = \frac{44}{tan 35}[/tex]
x = 62.83 ≈ 62.8
Using the 25° angle, you have the height which is 62.8 and looking for the side opposite the 25° angle.
So tan 23° = x/adjacent side
[tex]tan 25= \frac{x}{62.8}[/tex]
[tex]tan 25(62.8)= x[/tex]
29.28 ≈29.2 A = 1/2bh ; A = 1/2 (44 + 29.2)(62.8) ; A = 2298.48

CAN SOMEONE PLEASE HELP ME PLEASE PLEASE!!!
Step-by-step explanation:
this is really simple : we only need to put the given x and y coordinate values into both equations and see, if both equations remain true.
(-2, -1) means x = -2, y = -1
first equation :
-1 = 3×-2 + 5 = -6 + 5 = -1
so, -1 = -1
true.
second equation :
-2 + -1 = -3
-3 = -3
true.
therefore, (-2, -1) is a solution to the linear system.
the point is the crossing point of both lines.

Carla’s team won 3 of its 5 games played. Elena’s team won games at the same rate. How many games were played if Elena’s team won 12 games?
3/5=12/x
reciprical of both sides
5/3=x/12
times twelve on both sides
x=20
Answer:
7.2 games, 2.4 times rate.
Step-by-step explanation:
Carla's team won 3 of 5 games which is 3/5 aka 60%.
Elena's team won games at the same rate which means Elena's team won about 7 games since it's 7.2/12 (60%). They won at the rate of 2.4 times while Carla wins at 3/5 rate.
