Trent told his friends it would take him 90 minutes to mow the lawn. It only took him
75 minutes. What is his percent error?

Answers

Answer 1

Answer:

The answer is 16%

Step-by-step explanation:

use the percent error formula.

[tex]\frac{|E-T|}{|T|} *100[/tex]

in this problem,

e= 75

t=90

substitute and solve.

[tex]\frac{|75-90|}{|90|} *100\\\frac{|-15|}{|90|}*100\\\\ .16667*100\\[/tex]

16%

we are dealing with percents so rounding to nearest whole number will suffice.

hope this helps!

How do I write this equation? Pls help ASP

Answers

This is a question about angles and equations! Let's see how to solve this.

The angle [tex]\angle PQR[/tex] is the sum of the angles [tex]\angle MQR[/tex] and [tex]\angle PQM[/tex]. So, we can do a equation with this information and solve it:

[tex]\angle PQR = \angle MQR + \angle PQM\\\\138x -1 = 115 + 23x -1\\138x - 23x = 115 + 1 - 1\\115x = 115\\x=\frac{115}{115} \\x= 1[/tex]

Therefore, the value of x is 1.

The coordinates of point Y are giving. The midpoint XY is (3,-5). Find the coordinates of point X.

Y (4, -8)

Answers

Suppose the midpoint of XY is M ;

So ;

[tex] \frac{x + y}{2} = m \\ [/tex]

Multiply sides by 2

[tex]x + y = 2m[/tex]

( x , y ) + ( 4 , - 8 ) = ( 2 × 3 , 2 × -5 )

( x , y ) + ( 4 , - 8 ) = ( 6 , -10 )

( x , y ) = ( 6 , -10 ) - ( 4 , - 8 )

( x , y ) = ( 6 - 4 , -10 + 8 )

( x , y ) = ( 2 , - 2 )

So the coordinates of the point X is :

X = ( 2 , - 2 )
