W varies directly as r cubed and inversely as s. If w=24 when r= 4 and s= 8, find out when w= 81 and s= 27
Answers
Answer:
a) Given that w=81 and k = 0.375 then r = 6
b) Given that s=27 and k = 224 then w=32
Step-by-step explanation:
Step(i):-
Given that W varies directly as r³
⇒ w∝r³
⇒ w = kr³
where 'k' is proportionally constant
given that w= 24 and r =4
⇒ 24 = k (4)³
⇒ k = [tex]\frac{24}{64}[/tex]
⇒ k = 0.375
Step(ii):-
Given that W varies indirectly as 's'
w ∝[tex]\frac{1}{s}[/tex]
W =k [tex]\frac{1}{s}[/tex]
where 'k' is proportionally constant
28 = k ([tex]\frac{1}{8}[/tex])
k = 28 × 8 = 224
Step(iii):-
a) Given that w=81 and k = 0.375
w = kr³
81 = 0.375 (r)³
r³ = 216
r = ∛216 =6
r =6
b)
Given that s=27 and k = 224
W =k [tex]\frac{1}{s}[/tex]
w = 224 ([tex]\frac{1}{27}[/tex])
w = 32
here is a rule for a sequence. After the first two terms, each term is half the sum of the previous two terms.
Answers
Answer:
Step-by-step explanation:
A)
(22+12)/2 = [17] (12+17)/2 = [14.5] (17+14.5)/2 = [15.75]
B)
(10.5*2) - 5 = [16] ......... NOT 13
1. The Complete Sequence is 2, 22, 12, 17, 14.5, 15.75.
2. The second term is 16.
What is Sequence?A grouping of numbers in a specific order is known as a sequence. On the other hand, a series is described as the accumulation of a sequence's constituent parts.
Given:
1. 2 22 12 _ _ _
So, the rule is ( sum of consecutive terms) /2
Then, the fourth term is
= (22+12)/2
= 17
and, fifth term is
=(12+17)/2
= 14.5
and, sixth term is
= (17+14.5)/2
= 15.75
So, the Complete Sequence is 2, 22, 12, 17, 14.5, 15.75
2. First term =5 and 3rd term = 10.5
Again, third term = ( 5 + x ) /2
21 = 5 + x
x = 16

The product 3 of and Diego's score is 45 . Use the variable d to represent Diego's score.
Answers
Answer:
3 x d = 45
Step-by-step explanation:
d = 15
Multiply 3 x d which d equals 15 and multiply 3 x 15 = 45. So d = 15
Answer:
45 = 3d
d = 15
Product means the numbers are being multiplied together
Since it is 3 and Diego's score (d) it would be 3d
Whatever is being multiplied to d would be 45
15 x 3 = 45
That would complete the equation

there were 62 people in the movie theater for the matinee. ticket sales for that showing were $364. if adult tickets cost $7 and children tickets cost $3.50, how many of each were at that show. please solve with systems of equations.
Answers
Answer:
Step-by-step explanation:
a+c=62, c=62-a
7a+3.5c=364, using c found above gives you
7a+3.5(62-a)=364 expand left side
7a+217-3.5a=364 group like terms on left side
3.5a+217=364 subtract 217 from both sides
3.5a=147 divide both sides by 3.5
a=42, since c=62-a
c=62-42=20
So 20 children and 42 adult tickets were sold.

[tex]x=4[/tex]
Step-by-step explanation:
By the Triangle Proportionality Theorem:
[tex]\displaystyle \frac{x}{12}=\frac{x+1}{15}[/tex]
By cross-multiplication:
[tex]\displaystyle 12(x+1)=15(x)[/tex]
Distribute:
[tex]12x+12=15x[/tex]
Subtract 12x from both sides:
[tex]12=3x[/tex]
Hence:
[tex]x=4[/tex]
Answer:
4
Step-by-step explanation:
The first thing you should notice is that the triangles (the smaller one and the larger one) are similar due to angle-angle similarity (the top angle equals itself, and because the bases are parallel lines cut by a transversal, the base angle of the bigger triangle is equal to the corresponding base of the smaller triangle.
Similar triangles' corresponding sides have equal ratios to one another. That means we can set up an equation: side of smaller triangle ÷ corresponding side of larger triangle = other side of smaller triangle ÷ corresponding side of larger triangle. We plug the values given to us and can change this equation to:[tex]\frac{x}{x + 12} = \frac{x + 1}{x + 16}[/tex] **
We now multiply both sides of the above equation by [tex](x + 12)(x + 16)[/tex] to get: [tex]x(x + 16) = (x + 1)(x + 12)[/tex]
[tex]x^{2} + 16x = x^{2} + 13x + 12[/tex]
[tex]3x = 12[/tex]
[tex]x = 4[/tex]
That means our answer, for the value of x, is 4
** Make sure you don't say [tex]\frac{x}{12} = \frac{x + 1}{15}[/tex], because those aren't the sides of the larger square.
