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%

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

*Answer**
To get the Greates Common Factor (GCF) of 1700 and 1938 we need to factor each value first and then we choose all the copies of factors and multiply them:
1700: 2 2 5 5 17
1938: 2 3 17 19
GCF: 2 17

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:
Given
sin jk = 8/3
According to SOH CAH TOA
Sin theta = opposite/hypotenuse = 8/3
Opposite = 8
hypotenuse = 3
Get the adjacent using the pythagoras theorem
hyp² = opp²+adj²
adj² = hyp² - opp²
adj² = 3² - 8²
adj² = 9-64
adj² = -55
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

5x+5+4x=4-3x+6 simplified
Answer:
see below
Step-by-step explanation:
5x+5+4x=4-3x+6
Combine like terms
9x+5 = 10-3x
Add 3x to each side
9x+3x +5 = 10-3x+3x
12x+5 = 10
Subtract 5 from each side
12x+5-5 = 10-5
12x = 5
Divide each side by 12
12x/12 = 5/12
x=5/12
The value of a car, C(t), t years after 2011, is modeled by the following function.
C(t) = 50,000(0.9)^t - 2,000
Which graph represents this function?
9514 1404 393
Answer:
B
Step-by-step explanation:
At t=0, the value is ...
C(0) = 50,000·(0.9^0) -2000 = 48,000
At t=20, the value is ...
C(20) = 50,000(0.9^20) -2000 = 6079 -2000 = 4079
The only graph that matches these end points is B.
Answer:
The correct answer is Graph B depicted in the picture.

Thank You So Much❤️✨
Answer:
[tex]\underline{192}, 24, \underline{3}, \underline{\dfrac{3}{8}}, \dfrac{3}{64}[/tex]
[tex]\underline{\dfrac{1}8}, \dfrac{1}{4}, \dfrac{1}{2}, \underline{1}[/tex]
[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]
