Given :
Distance covered by object , D = 63 cm .
Time taken to cover distance D , t = 2 days .
To Find :
The speed of object in m/s .
Solution :
First we will convert all units into m and hours .
D = 63 cm = 0.63 m .
[tex]t=2\ days =2\times 24\ hours =48\ hours[/tex] .
Now , speed is :
[tex]s=\dfrac{D}{t}\\\\s=\dfrac{0.63}{48}\ m/hours\\\\s=0.013\ m/hours[/tex]
Hence , this is the required solution .
Answer:63
Step-by-step explanation:
Hillary’s summer job at the frozen yogurt shop paid her the amounts shown in the table below in her first three days on the job (she got paid the same hourly rate every day).
Answer:
P=9.0h
Step-by-step explanation:
Divide the Paid amount by the hours worked and you'll get how much money she gained every hour which is 8.50$ And the question is telling you which of the following equations is GREATER than the amount she got paid per hour. So the answer would be P=9.0h
The required equation represents an hourly pay rate that is greater than Hillary's hourly pay rate p = 9.0h. Option D is correct.
Given,
Hillary’s summer job at the frozen yogurt shop paid her the amounts shown in the table below in her first three days on the job (she got paid the same hourly rate every day).
day = 1 2 3
Hours worked(h) = 5 4 6
Amount paid (p) = $42.50 $34 $51
The slope of the line is the tangent angle made by line with horizontal. i.e. m = tanx where x in degrees.
The slope of the data given,
m = 42.5/5
m = 8.5
the slope shows the hourly rate to get paid.
Required expression is
p = 8.5h
From the option, the slope of equations needs to compare greater the slope greater will the hourly rate.
Slope of equation A = 1/8, B =8, C = 8.5 and D = 9.0
hence, only slope D has a greater value by the existing slope of 8.5
Thus, the required equation that represents an hourly pay rate that is greater than Hillary's hourly pay rate p = 9.0h.

4. Error Analysis Jacinta says that the product of a rational number and an irrational number is always irrational. Explain her error.
Answer:
She did not consider the multiplicative inverse property of a real number
Step-by-step explanation:
Jacinta in her conclusion did not consider the Multiplicative Inverse property of real numbers.
Let x be an irrational number.
So, [tex]$ x.\frac{1}{x}= 1$[/tex]
If x is an irrational number, then its reverse is also an irrational number. So by the Multiplicative Inverse property their product is 1 and 1 is a rational number. Thus, Jacinta was incorrect.

La suma de dos numeros es 208 y su diferencia es 122¿cuales son los numeros?
Answer:
Los números son:
43 y 165
Step-by-step explanation:
Planteamiento:
a + b = 208
a - b = 122
Desarrollo:
de la segunda ecuación del planteamiento:
a = 122 + b
sustituyendo este último valor en la primer ecuación del planteamiento:
(122+b) + b = 208
2b = 208 - 122
2b = 86
b = 86/2
b = 43
a = 122 + b
a = 122 + 43
a = 165
Comprobación:
165 + 43 = 208
165 - 43 = 122

Answer:
x=7 Hope this helps :)
Step-by-step explanation:
Let's solve your equation step-by-step.
2x+8+3x+6=7x
Step 1: Simplify both sides of the equation.
2x+8+3x+6=7x
(2x+3x)+(8+6)=7x(Combine Like Terms)
5x+14=7x
5x+14=7x
Step 2: Subtract 7x from both sides.
5x+14−7x=7x−7x
−2x+14=0
Step 3: Subtract 14 from both sides.
−2x+14−14=0−14
−2x=−14
Step 4: Divide both sides by -2.

Write an equation using the information in
terms of x. Find x, AB, and BC.
AB = 8x + 5
BC = 5x - 9
AC = 74
The equation is given as: 13x - 4 - 74 = 0
The value of x is 6
AB = 53
BC = 21
Given,
B is between points A and C on AC.
AB = 8x + 5
BC = 5x - 9
AC = 74
We need to write an equation using the information in terms of x
We also need to find x, AB, and BC.
If there is a point between two points of a line, the sum of the two lines separated by the point is equal to the line given.
Example:
M______N____________O
Then,
MN + NC = MO
Find the equation that represents AC with point B between A and C.
We have,
A______B___________C
AB = 8x + 5
BC = 5x - 9
AC = 74
Now,
AC = AB + BC
74 = 8x + 5 + 5x - 9
74 = 13x - 4
13x - 4 - 74 = 0
Find x.
74 + 4 = 13x
78 = 13x
x = 78 / 13
x = 6
Find AB
AB = 8x + 5
= 8x6 + 5
= 48 + 5
= 53
Find BC
BC = 5x - 9
= 5x6 - 9
= 30 - 9
= 21
Thus,
The equation is given as: 13x - 4 - 74 = 0
The value of x is 6
AB = 53
BC = 21
