Priya can bike 150 meters in 20 seconds at this rate , how long would it take her to bike in 3,000 meters???????? Does anyone know I’m stuck
Answers
Answer:
400 seconds
Step-by-step explanation:
150/20=7.5 meters per second
3000/7.5=400 seconds
Priya will take 400 seconds to cover distance of 3,000 meters.
What is speed?In unit time, the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
Distance covered by Priya in 20 seconds = 150 meters.
The speed of Priya = 150 / 20 = 15/2 meters per second
To find the time to cover the distance of 3,000 meter,
Use formula,
Time = distance / speed
Time = 3,000 / (15/2)
Time = 400 seconds
To cover 3,000-meter distance, Priya will take 400 seconds.

multiplicative inverse of negative 3
Answers
Answer: -1/3
Step-by-step explanation: In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/x or x-1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a/b is b/a. Sice -3 can also be shown as -3/1, all we do is flip this to get -1/3.
The multiplicative inverse of -3 is [tex]\frac{-1}{3}[/tex].
What is a multiplicative inverse?"The multiplicative inverse of a number is defined as a number that when multiplied by the original number gives the product as 1. The multiplicative inverse of 'x' denoted by [tex]\frac{1}{x}[/tex] or [tex]x^{-1}[/tex]."

The graph of the question is attached below.
A straight line graph is used to represent a linear equation. A linear equation is represented by the equation: y = mx + b, where y is the dependent variable, x is the independent variable, m is the rate of change and b is the intercept.
The equation of a line passing through two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is given as:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]
Let y represent the distance in miles and x represent the time in hours. From the graph, the line pass through (1.5, 300) and (2.5, 500). Hence using:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-300=\frac{500-300}{2.5-1.5} (x-1.5)\\\\y-300=200(x-1.5)\\\\y-300=200x-300\\\\y=200x-300+300\\\\y=200x\\\\To\ find\ the\ time\ taken\ to\ travel\ 480 \ miles,we\ substitute\ y=480\ \\\\480=200x\\\\x=480/200\\\\x=2.4\ hours[/tex]

Add 13 on both sides.
37x-13 = 90

Divide both sides by 37.

Answers
(............)
Answer:
1/5 (one fifth)
Step-by-step explanation:
if x is the length of the bedroom and y is the width then we can do big brain maffs
Length of floor = x
Width of floor = y
Length of bed = 3/5*x or 3x/5
Width of bed = 1/3*y or y/3
Area of floor = xy
Area of bed = 3x/5 * y/3 = xy/5
Area of bed/Area of floor = (xy/5) / xy = 1/5

The sum of the 2nd and 3rd terms of an arithmetic sequence is 27 and the sum of the 4th and 5th terms is 77.
Find the common difference of the sequence.
Give your answer as a decimal.
Answers
Answer:
d = 12.5
Step-by-step explanation:
Second term = a + d
Third term = a + 2d
a + d + a + 2d = 27
2a + 3d = 27
Fourth term = a + 3d
Fifth term = a + 4d
a + 3d + a + 4d = 77
2a + 7d = 77
2a + 3d = 27 (1)
2a + 7d = 77 (2)
Subtract (1) from (2) to eliminate a
7d - 3d = 77 - 27
4d = 50
Divide both sides by 4
d = 50/4
= 12. 5
d = 12.5
Substitute d = 12.5 into (1)
2a + 3d = 27
2a + 3(12.5) = 27
2a + 37.5 = 27
2a = 27 - 37.5
2a = -10.5
a = -10.5 / 2
= -5.25
a = -5.25
The common difference of the sequence is 12.5.
Given that,
The sum of the 2nd and 3rd terms of an arithmetic sequence is 27,
And the sum of the 4th and 5th terms is 77.
We have to determine,
The common difference of the sequence?
According to the question,
Let d is the common difference of the sequence,
The second term to the arithmetic series is,
[tex]\rm Second \ term= a+d[/tex]
And the third term to the arithmetic series is,
[tex]\rm Third \ term= a+2d[/tex]
The sum of the second and third terms of the sequence is 27.
[tex]\rm Second \ term + third \ term = 27\\\\a+d + a+2d = 27\\\\2a + 3d = 27[/tex]
The fourth term to the arithmetic series is,
[tex]\rm fourth \ term= a+3d[/tex]
And the fifth term to the arithmetic series is,
[tex]\rm fifth \ term= a+4d[/tex]
The sum of the fourth and fifth terms of the sequence is 77.
[tex]\rm fourth\ term + fifth \ term = 77\\\\a+3d + a+4d = 77\\\\2a + 7d = 77[/tex]
On solving both the equations,
[tex]\rm 2a + 3d = 27\\\\2a + 7d = 77[/tex]
Subtract equation 1 from equation 2,
[tex]\rm 2a + 3d - (2a + 7d) = 27-77\\\\2a +3d -2a-7d = -50\\\\-4d = -50\\\\d = \dfarc{-50}{-4}\\\\d = \dfrac{25}{2}\\\\d = 12.5[/tex]
Hence, The required common difference of the sequence is 12.5.

What is the image point of (-4, 2) after a translation left 1 unit and down 2 units?
Answers
Answer:
(- 5, 0 )
Step-by-step explanation:
A translation of 1 unit left means subtract 1 from the x- coordinate.
A translation of 2 units down means subtract 2 from the y- coordinate.
(- 4, 2 ) → (- 4 - 1, 2 - 2 ) → (- 5, 0 )
The translated coordinate is (-5, 0).
What is Translation?A transformation known as a translation involves shifting each point in a figure by the same amount and in the same direction.
Translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.
Given:
Image point (-4, 2)
And, now we have to translate the figure left 1 unit and down 2 units
So, A translation of 1 unit left means subtract 1 from the x- coordinate.
and translation of 2 units down means subtract 2 from the y- coordinate.
Thus, (- 4, 2 ) ----> (- 4 - 1, 2 - 2 ) ----> (- 5, 0 )
Hence, the translated coordinate is (-5, 0).
