HELP WITH EQUATION
Answers
I think the answer its 1.8 percent because if you subtract 15-13.2 comes out to be 1.8.
but l also think it could be 12 percent error.
The odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is [tex]12 \%[/tex] .
What is percentage ?A percentage is a number or ratio that can be expressed as a fraction of 100. And is denoted using the percent sign, "[tex]\%[/tex]".
Percentage [tex]=\frac{Diffeerence \ in \ value}{Total \ value}[/tex]
We have,
Last trip to the hardware store [tex]=13.2[/tex] miles
Original trip to the hardware store [tex]=15[/tex] miles
So,
Using the above given formula;
Percentage error [tex]=\frac{Diffeerence \ in \ value}{Total \ value}*100[/tex]
[tex]=\frac{15-13.2}{15} *100[/tex]
[tex]=\frac{1.8}{15} *100[/tex]
[tex]=12 \%[/tex]
So, the Percentage error in the odometer is [tex]12 \%[/tex] which is find out using above given formula.
Hence, we can say that the odometer recorded [tex]13.2[/tex] miles for his last trip to the hardware store, but he knows the distance traveled is [tex]15[/tex] miles then the percent error is [tex]12 \%[/tex] .

Step-by-step explanation:
The kind of symmetry the figure given above posses is a line and point symmetry.
What is point symmetry?A point Symmetry also known as origin symmetry is a Symmetry which occurs when every part of an object has a matching part. That is, the same distance from the central point but in the opposite direction.
Given that;
The objects looks the same when viewed from opposite directions.
We know that;
A line of symmetry is a line that cuts a shape exactly into two equal half. That is, if you fold the shape along the line, both halves would match exactly.
Therefore, the figure given above has both point and line Symmetry.

Step-by-step explanation:
Let n be the number of days he has been doing sit ups, not counting the first day. Since he does 2 more sit-ups for each day, then the number of additional sit-ups is 2n.
Since he started doing 15 sit-ups on the first day, the total number of sit-ups
after x days would be 2n+15.
Since he did a total of 33 sit ups today, then 2n+15=33

Model requiring 525 block and 290 blocks
What is scale factor ?Scale Factor is used to scale shapes in different dimensions. In geometry, we learn about different geometrical shapes which both in two-dimension and three-dimension. The scale factor is a measure for similar figures, who look the same but have different scales or measures. Suppose, two circle looks similar but they could have varying radii.
a) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 2 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 2.
Number of blocks=1,450 feet * (1 block/2 feet)
Number of blocks = 725 blocks
Therefore, you would use a model requiring 725 blocks.
The scale factor for the model is 1 block per two feet.
b) You have two given data available here: the actual height of the Empire State Building measuring 1,450 feet, and the height of the block measuring 5 feet. To find how many blocks stacked together would make up 1,450 feet, just divide 1,450 by 5.
Number of blocks=1,450 feet * (1 block/5 feet)
Number of blocks = 290 blocks
Therefore, you would use a model requiring 290 blocks.
The scale factor for the model is 1 block per five feet.
