Step-by-step explanation:
The ratio of fiction books to nonfiction books on the shelf is, 4
What is the ratio?A ratio in mathematics is a comparison of two or more numbers that shows how big one is in comparison to the other. The dividend or number being divided is referred to as the antecedent, while the divisor or number that is dividing is referred to as the consequent.
Given that,
Ellie has 20 books on her shelf
Four of these books are nonfiction
The rest are fiction
The ratio of fiction books to nonfiction books on the shelf = ?
The number of fiction books = ?
The number of fiction books = 20 - 4
= 16
Ratio = fiction/nonfiction
= 16/4
= 4
Hence, the ratio is 4

Manuel y Sara recorren cierta distancia, y los tiempos que emplean están en la razón 21 / 15 . La velocidad de Manuel es de 56km/h. ¿Cuál es la velocidad de Sara?
Answer:
The speed of Sara is 78.4 km/h.
Step- by-step explanation:
Manuel and Sara travel a certain distance, and the times they use are in the ratio 21/15. Manuel's speed is 56km / h. What is Sara's speed?
Let the distance is d.
speed of Manuel = 56 km/h
time taken by Manuel = 21 t
time taken by Sara = 15 t
Let the speed of Sara is v.
Distance = speed x time
For Manuel:
d = 56 x 21 t ..... (1)
For Sara:
d = v x 15 t ..... (2)
From (1) and (2)
56 x 21 t = v x 15 t
v = 78.4 km/h

y-3=2(x-3) y+5=2(x+1)
choose 1 answer
the same line
distinct parallel lines
Perpendicular lines
intersecting, but not perpendicular lines
Answer:
The same lines (answer)
Step-by-step explanation:
The equations can be written in slope-intercept form y = mx + c (where 'm' is slope and 'c' is the y-intecept) as,
y-3 = 2(x-3) .......(1) ; y + 5 = 2(x+1) ...........(2)
y = 2x - 6 + 3 ; y = 2x + 2 - 5
y = 2x -3 ; y = 2x - 3
Comparing with slope intercept form we have,
m1 = 2 ; m2 = 2
c1 = -3 ; c2 = -3
If the slopes are equal the lines are parallel and since y-intercepts are also equal means they are the same lines (overlapping)

the LCM is 2Thanks Hope It HelpA jar is filled with 74 different colored marbles, 10 of which are red, 38 of which are blue, and 26 of which are green. A player is asked to draw a single marble from the jar and if they draw a red marble they will win $20, if they draw a blue marble they will lose $10, and if they draw a green marble they will lose $5. You may round your answer to the nearest cent
Solution :
Colored marble Prize
Red ---- 10 20
Blue --- 38 10
Green --- 26 5
P(red) = 10/74 = 5/37
P(blue) = 38/74 = 19/37
P( green) = 26/74 = 13/37
Therefore,
X → Red Blue Green
P(X) 5/37 19/37 13/37
The expected values are :
[tex]$20 \times \frac{5}{37} - 10 \times \frac{19}{37} - 5 \times \frac{13}{37}[/tex]

Which of the following accurately describes the median of a set of data? Multiple choice question. The midpoint of the data when it is arranged in order. The difference in the largest and smallest values. The most numerous observation in a set of data. The arithmetic average of the values in the set.
Answer:
The midpoint of the data when it is arranged in order.
Step-by-step explanation:
Median can be described as the number that occurs in the middle of a set of numbers that are arranged either in ascending or descending order
For example, the median of the following set of numbers is 5
1, 2, 5, 10, 20
Range is the difference between the highest and lowest values of a set of observations
Range = highest value - lowest value
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number

Piece-wise function:
A piece-wise function is a function that has different definitions, depending on the input.
In this question, the function has three different definitions:
When x is less than -2, the definition is:
[tex]g(x) = \frac{x}{2} + 3[/tex]
When x is between -2 and 3, inclusive, the function is:
[tex]g(x) = 2[/tex]
When x is greater than 3, the definition is:
[tex]g(x) = 2x - 3[/tex]

What sum of money amount to Rs 6000 in two years at the rate of 10% per annum find it
Answer: Rs 5000 sum of money amount to Rs 6000 in two years at the rate of 10% per annum.
Step-by-step explanation:
Amount = Rs 6000
T = 2 year
R = 10%
So
I = A-P
so
I = PTR/100
or, A-P = (P*2*10)/100
or, 6000-P = 20P/100
or, 600000-100P = 20P
or, 600000 = 120P
or, P = 600000/120
so, P = Rs 5000

Can someone help me with this math problem please?
Answer:
C
Step-by-step explanation:
g(x) is larger than f(x) and not the same size so B and D are out of question because those are translation not dilation.
f(x) is stretched in the vertical direction to get g(x). So this means the scale factor has to be greater than 1. so A is wrong.

Find the sum that amounts to Rs 9,144 in 3 years at 9% per year simple interest.
Given:
Amount = Rs. 9,144
Time = 3 years.
Rate of simple interest = 9%
To find:
The principal value.
Solution:
The formula for simple interest is:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the simple rate of interest, and t is the number of years.
Putting [tex]r=9,t=3[/tex] in the above formula, we get
[tex]I=\dfrac{P\times 9\times 3}{100}[/tex]
[tex]I=\dfrac{27P}{100}[/tex]
[tex]I=0.27P[/tex]
We know that,
[tex]\text{Amount}=\text{Principal + Interest}[/tex]
[tex]9144=P+0.27P[/tex]
[tex]9144=1.27P[/tex]
Divide both sides by 1.27, we get
[tex]\dfrac{9144}{1.27}=P[/tex]
[tex]7200=P[/tex]
Therefore, the principal value is Rs. 7200.
