At the start of the month, Stephen’s savings account had a balance of $1,624. He made a $420 withdrawal each week for four weeks

goldenfox [79]

420 x 4 = 1,680. $1,624 - $1,680 = - $56. $600 x 2 = 1,200 + 1000 = 2,200. This minus the $56 he overdrew = an end of month balance of $2,144.

Triangle Abc has vertices A(-2,5),B(1,0),andC(6,-2).what are the coordinates of the vertices of A’B’C for Ry-axis?

Andreyy89

Answer:

A'(2,5),B'(-1,0),C'(-6,-2)

Step-by-step explanation:

we know that

The rule of the reflection of a point across the y-axis is equal to

(x,y) -----> (-x,y)

Applying the rule of the reflection across the y-axis

A(-2,5) ----> A'(2,5)

B(1,0) -----> B'(-1,0)

C(6,-2) ---> C'(-6,-2)

Twice jacks age plus five is 21. Write and solve an equation. How old is jack

Vera_Pavlovna [14]

Answer:

Jack is 8

Step-by-step explanation:

j= jacks age

2j+5 =21

This is the equation from Twice jacks age plus five is 21

We want to isolate j

Subtract 5 from each side

2j+5 =21

2j+5-5 = 21-5

2j = 16

Divide by 2

2j/2 =16/2

j =8

In high school, some students have been confused to believe that 22/7 is already the actual value of π or an acceptable approxim

jarptica [38.1K]

Answer:

Since it has smaller absolute and relative errors, 355/113 is a better aproximation for $\pi$ than 22/7

Step-by-step explanation:

The formula for the absolute error is:

Absolute error = |Actual Value - Measured Value|

The formula for the relative error is:

Relative error = |Absolute error/Actual value|

I am going to consider the actual value of $\pi$ as 3.14159265359.

In the case of 22/7:

22/7 = 3.14285714286.

Absolute error = |3.14159265359 - 3.14285714286| = 0.00126448927

Relative error = 0.00126448927/3.14159265359 = 0.00040249943 = 0.04%

In the case of 355/113

355/113 = 3.14159292035

Absolute error = |3.14159265359 - 3.14159292035| = 0.00000026676

Relative error = 0.00000026676/3.14159265359 = 0.000000085 = 0.0000085%

Since it has smaller absolute and relative errors, 355/113 is a better aproximation for $\pi$ than 22/7
