Answer:
1738
Step-by-step explanation:
Melissa has $11 remaining after purchasing 3.6 pounds of candy that cost $2.50 per pound.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Melissa had $20 to purchase candy for a party.
She purchased 3.6 pounds of candy that cost $2.50 per pound
Melissa spent 3.6 x $2.50
= 9 on candy.
Subtracting this amount from her initial $20, we get:
$20 - $9 = $11
Therefore, Melissa has $11 remaining after purchasing 3.6 pounds of candy that cost $2.50 per pound.

Distance = ________ x time
A. flow
B. rate
C. work
Answer:
B:rate
Step-by-step explanation:
the formula distance= rate × time
Answer:
B
Step-by-step explanation:
The formula for distance is rate × time.
Flow and work don't make sense. Also, work is force × distance.
However, you were given rate is equal to distance/time (r=d/t) and were asked to find what distance would be:
in that case, we'll isolate d onto one side
here's the equation
r=d/t
multiply by t on both sides
rt=d, or rate × time equals distance
either way it's B

what is the sum of the geometric sequence -3,18,-108,.. if there are 7 terms?
Answer:
[tex]S_{7}[/tex] = - 119973
Step-by-step explanation:
The sum to n terms of a geometric sequence is
[tex]S_{n}[/tex] = [tex]\frac{a(r^n-1)}{r-1}[/tex]
where a is the first term and r the common ratio
Here a = - 3 and r = 18 ÷ - 3 = - 6 , thus
[tex]S_{7}[/tex] = [tex]\frac{-3(-279936-1)}{-6-1}[/tex]
= [tex]\frac{-3(-279937)}{-7}[/tex]
= [tex]\frac{839811}{-7}[/tex]

Search cos jk and tan jk knowing that sin jk = 8/3
Answer:
cosjk = √55 i/3
tanjk = 8/√55 i
Step-by-step explanation:

Get the adjacent using the pythagoras theorem
hyp² = opp²+adj²
adj² = hyp² - opp²
adj² = 3² - 8²

adj = √-55
adj = √55 i (i = √-1)
Get cosjk
cosjk = adj/hyp
cosjk = √55 i/3
Get tanjk
tanjk = opp/adj
tanjk = 8/√55 i

sin 2x = 2 sin x cos xMultiply LHS by 2sinx/2sinx:
2sinx cos x cos 2x cos 4x cos 8x / 2 sin x = sin 2x cos 2x cos 4x cos 8x / 2 sin x = 2sin 2x cos 2x cos 4x cos 8x / 4 sin x =sin 4x cos 4x cos 8x / 4 sin x =2sin 4x cos 4x cos 8x / 8 sin x =sin 8x cos 8x / 8 sin x =2 sin 8x cos 8x / 16 sin x =sin 16x / 16 sin xNow, we can easily find that:
sin (16*2π/15) = sin (2π/15)Coming back to the original equation, we get:
cos (2π/15) cos (4π/15) cos (8π/15) cos (16π/15) = sin (16*2π/15) / 16 sin (2π/15) cos (2π/15) cos (4π/15) cos (8π/15) cos (16π/15) = 1/16What is the LCM of 168 and 196.

Answer:
The team made x<53 points total.
Step-by-step explanation:
1/4+1/10 is 7/20 or 0.35 in decimal form. If they both together scored 21 points then you can add another 7/20 (21 points) and have 14/20 (42 points). You have 6/20 more left. If you can solve what 1/20 could be then you would find the answer. Does this helps?
Answer:
The total number of points scored is 60.
Step-by-step explanation:
We can multiply a number to both fractions to get them to share a common denominator so we can add them easily. 20 is a multiple of both 4 and 5, so let us multiply both denominators so that they each have a denominator of 20.
1/10 * 2 = 2/20
1/4 * 5 = 5/20
Now we can add those fractions together because we want to see the total amount of points the team scored.
2/20 + 5/20 = 7/20
If 7/20 is 21 points, we can find out how much points takes up 1/20 of the fraction. We do this by dividing 21 by 7.
21 / 7 = 3
So 1/20 = 3
Now we multiply 3 by 20, which is 60. So therefore the total amount of points scored by the team is 60. Brian scored 1/10 of 60, which is 6. So he scored 6 points. Joe scored 1/4 of 60, which is 15. So Joe scored 15 points. Hope this helps.

[tex]81, \underline{27, 9, 3, 1},\dfrac{1}{3}[/tex]
Step-by-step explanation:
Given the Geometric sequences:
1. ___, 24, ___, ___, 3/64
2. ___, 1/4, 1/2, ___
3. 81, ___, ___, ___, ___, 1/3
To find:
The values in the blanks of the given geometric sequences.
Solution:
First of all, let us learn about the [tex]n^{th}[/tex] term of a geometric sequence.
[tex]a_n=ar^{n-1}[/tex]
Where [tex]a[/tex] is the first term and
[tex]r[/tex] is the common ratio by which each term varies from the previous term.
Considering the first sequence, we are given the second and fifth terms of the sequences.
Applying the above formula:
[tex]ar = 24\\ar^4 = \dfrac{3}{64}[/tex]
Solving the above equation:
[tex]r = \dfrac{1}{8}[/tex]
Therefore, the sequence is:
[tex]\underline{192}, 24, \underline{3}, \underline{\dfrac{3}{8}}, \dfrac{3}{64}[/tex]
Considering the second given sequence:
[tex]ar = \dfrac{1}{4}\\ar^2 = \dfrac{1}{2}\\\text{Solving the above equations}, r = 2[/tex]
Therefore, the sequence is:
[tex]\underline{\dfrac{1}8}, \dfrac{1}{4}, \dfrac{1}{2}, \underline{1}[/tex]
Considering the third sequence:
[tex]a = 81\\ar^5=\dfrac{1}{3}\\\Rightarrow r = 3[/tex]
Therefore, the sequence is:
[tex]81, \underline{27, 9, 3, 1},\dfrac{1}{3}[/tex]
by what percent will a fraction change if its numerator is decreased by 75% and denominator is decreased by 50%
Answer:
50%
Step-by-step explanation:
first the numerator is decreased by 75% so its 0.25. the denominator is decreased by 50% so its 0.5. Then, we will divide 0.25 and 0.5 which equals 0.5. to find %, do 0.5*100 which equals 50%
The fraction will decrease by 0.5 or 50%
Let the original fraction be a/b. If the numerator is decreased by 75% and the denominator is decreased by 50%, the resulting faction will be:
0.25a/0.50b
Taking the ratio of the quotient of the result will give:
0.25a/0.50b
= 25/100a * 100/50 b
= 25a/50b
= 0.5a/b
Hence the fraction will decrease by 0.5 or 50%
