Answer:
yes
Step-by-step explanation:
it is possible that a body can be moving and at rest at the Same time. this is relative motion. an object that seem to be in motion for one subject can be stationary for another.
For example, A passenger in a bus. he/she is moving for a person walking on the pathway. but for the passenger next to him/her, they are at rest.
Answer:
Yes
Step-by-step explanation:
It is possible if you take into account different points of reference.
If you are in a car, sitting on a seat, while the car is moving, you are not moving with respect with the car. Since the car is moving with respect to the ground, you are moving with respect to the ground.
If you think bigger, you are always in motion. You may be standing in a position not moving at all with respect to the ground, but since the Earth is moving around the sun, you are moving with respect to the sun.
Which equation is equivalent to 16x – 8 + 2x = 100?
Answer:
x=6
Step-by-step explanation:
16x-8+2x=100
18x-8=100
18x=100+8
18x=108
x=108/18
x=6
14x=108 is the equivalent equation of the equation 16x – 8 + 2x = 100.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 16x – 8 + 2x = 100.
Sixteen times of x minus eight plus two times of x equal to hundred.
16x – 8 + 2x = 100.
We need to add the variable terms to get the equivalent equation.
Equivalent equation is an equation which looks different but the result will be same.
14x-8 = 100.
Add 8 on both sides.
14x=100+8
14x=108.
Hence, 14x=108 is the equivalent equation of the equation 16x – 8 + 2x = 100.

Asa saves dimes and quarters so that he will have exact change for he bus. He dabs and then dumps the container that he has been using for collecting his coins and finds he has 47 coins that are worth $9.50. How many of each coin does he have?
Answer:
He have 32 quarters and 15 dimes.
Step-by-step explanation:
Given:
Asa saves dimes and quarters so that he will have exact change for the bus.
He has 47 coins that are worth $9.50.
Now, to find the number of coin each he have.
Let the number of quarters be [tex]x.[/tex]
And the number of dimes be [tex]y.[/tex]
So, the total number of coins are:
[tex]x+y=47.[/tex]
[tex]y=47-x.[/tex].........(1)
As given the total worth of coins = $9.50
And the value of a quarter = $0.25 and the value of a dime = $0.10.
Now, the total worth of coins are:
[tex]0.25x+0.10y=9.50[/tex]
Putting the equation (1) in the place of [tex]y[/tex] we get:
[tex]0.25x+0.10(47-x)=9.50[/tex]
[tex]0.25x+4.7-0.10x=9.50[/tex]
[tex]0.15x+4.7=9.50[/tex]
Subtracting both sides by 4.7 we get:
[tex]0.15x=4.80[/tex]
Dividing both sides by 0.15 we get:
[tex]x=32.[/tex]
The number of quarters = 32.
Now, putting the value of [tex]x[/tex] in equation (1) we get:
[tex]y=47-32.[/tex]
[tex]y=15.[/tex]
The number of dimes = 15.
Therefore, he have 32 quarters and 15 dimes.

x = - 19
Step-by-step explanation:
Given
[tex]\frac{5x-3}{2}[/tex] = 3x + 8
Multiply both sides by 2 to clear the fraction
5x - 3 = 6x + 16 ( subtract 6x from both sides )
- x - 3 = 16 ( add 3 to both sides )
- x = 19 ( multiply both sides by - 1 )
x = - 19

Answer:
Weight of each large box [tex]x=15.75kg[/tex]
Weight of each small box [tex]y=13.75kg[/tex]
Step-by-step explanation:
Given:- Two equations are given,
Equation 1 :- [tex]7x+9y=234[/tex]
Equation 2:- [tex]5x+3y=120[/tex]
let,
x=weight of large box in Kilogram.
y=weight of small box in Kilogram.
Now,
multiply Equation 1 by 2 and Equation 2 by 6,
So we get 2 new equations,
Equation 3:- [tex]14x+18y=468[/tex]
Equation 4:- [tex]30x+18y=720[/tex]
Now after subtracting Equation 3 from Equation 4 we will get a new equation,
i.e. Equation 5:- [tex]16x=252[/tex]
therefore [tex]x=15.75[/tex]
now, put the value of x in Equation 1, so we will get
[tex](7x15.75)+9y=234[/tex]
[tex]110.75+9y=234[/tex]
[tex]9y=234-110.75[/tex]
[tex]9y=123.75[/tex]
[tex]y=123.75/9[/tex]
[tex]y=13.75[/tex]
So, weight of each large box i.e. [tex]x=15.75 kilogram[/tex]
and weight of each small box i.e. [tex]y=13.75 kilogram[/tex]

Which of the following rational numbers represents a repeating decimal 11 / 40 ,3/25, 25/48,or 7/32
[tex]\frac{25}{48}[/tex] represents repeating decimal
Solution:
We are asked to find the rational number that represents repeating decimal
A repeating decimal, also called a recurring decimal, is a number whose decimal representation eventually becomes periodic (i.e., the same sequence of digits repeats indefinitely)
Option 1
[tex]\frac{11}{40} = 0.275[/tex]
So here the decimal part is not repeating. So [tex]\frac{11}{40}[/tex] does not represent repeating decimal
Option 2
[tex]\frac{3}{25} =0.12[/tex]
So here the decimal part is not repeating. So [tex]\frac{3}{25}[/tex] does not represent repeating decimal
Option 3
[tex]\frac{25}{48} = 0.52083333333[/tex]
So here in decimal part "3" is repeating and goes on forever
So [tex]\frac{25}{48}[/tex] represents repeating decimal
Option 4
[tex]\frac{7}{32} = 0.21875[/tex]
So here the decimal part is not repeating. So [tex]\frac{7}{32}[/tex] does not represent repeating decimal

Y= ____________
Answer:
x = 11, y = 3
Step-by-step explanation:
9x + 25 and 13x - 19 are corresponding angles and congruent, thus
13x - 19 = 9x + 25 ( subtract 9x from both sides )
4x - 19 = 25 ( add 19 to both sides )
4x = 44 ( divide both sides by 4 )
x = 11
Thus
13x - 19 = (13 × 11) - 19 = 143 - 19 = 124°
13x- 19 and 17y + 5 form a straight angle and are supplementary, thus
13x - 19 + 17y + 5 = 180, that is
124 + 17y + 5 = 180
129 + 17y = 180 ( subtract 129 from both sides )
17y = 51 ( divide both sides by 17 )
y = 3
a bag contains 5 red, 6 white, and 5 blur marbles. a marble is drawn from the bag and replaced 32 times. the table shows the results. for which color is the experimental probability of drawing the color the same as the theoretical probability?
red:12 white: 12 blue:8
Answer:
White.
Step-by-step explanation:
Theoretical probabilities are:
Red: 5 / ( 5 + 6 + 5) = 5/16
White: 6/16 = 3/8.
Blue: 5/16.
The answer is white because it is drawn 12 times which equals its theoretical probability: 12/32 = 3/8.
The probability of drawing the color the same as the theoretical probability is 3/8.
What is Probability?Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.
The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The degree to which something is likely to happen is basically what probability means.
Given:
A bag contains 5 red, 6 white, and 5 blue marbles.
Theoretical probabilities for the colors are:
Red:
= 5 / ( 5 + 6 + 5)
= 5/16
White:
= 6/16
= 3/8.
Blue: 5/16.
So, the probability of drawing the color the same as the theoretical probability is white because the theoretical probability is 3/8.
