Answer:
Percent error = 6.25%
Step-by-step explanation:
Percentage error can be defined as a measure of the extent to which an experimental value differs from the theoretical value.
Mathematically, it is given by this expression;
[tex] Percent \; error = \frac {experimental \;value - theoretical \; value}{ theoretical \;value} *100[/tex]
Given the following data;
Experimental value = 4.5cm
Theoretical value = 4.8cm
Substituting into the equation, we have;
[tex] Percent \; error = \frac {4.8 - 4.5 }{ 4.8} *100[/tex]
[tex] Percent \; error = \frac {0.3}{4.8} *100[/tex]
[tex] Percent \; error = 0.0625 *100[/tex]
Percent error = 6.25%

The triangle has 3 sides and angles. The measure of "d" from the given diagram is 6.48
Application of SOH CAH TOAThe given diagram is a triangle. According to the SOH CAH TOA identity;
tan theta= opp/adj
Given the following
opp = d
adj = 7.2
Substitute
tan 42 = d/7.2
d = 7.2tan42
d = 6.48
Hence the measure of "d" from the given diagram is 6.48

Step-by-step explanation:
[tex]m=\frac{rise}{run}=\frac{4+2}{1-0}=\frac{6}{1}=\boxed{6}[/tex]
Hope this helps!
Answer:
The slope is 6.
Step-by-step explanation:
Using rise over run or

Step-by-step explanation:
Reed is purchasing an X-Box One. He made an initial payment of $75 to the store, and will pay $15 each month until the system is paid off. Which equation represents the relationship between x, the number of monthly payments Reed has paid, and t, the total amount that Reed has paid the store?
A. t = 75x + 15 C. t = 15x + 75
B. t = 15x - 75 D. Not Here
C.) T=15x+75
its 15 dollars each month and since you don't know the number of months the variable would correspond with 15 and you just need to add 75 onto it
Answer:
C. t = 15x + 75
Step-by-step explanation:
since you already payed the 75 dollars you add it and you multiply 15 by x because x is the number of months you pay
F(n)=2n+5. Find the 5th term in the sequence

a farmer needs to build a goat pen. the pen will be 9 yards wide and 18 yards long. The fencing material costs 8.98 per yard. how much will it cost to buy enough fencing material
Answer:
$484.92
Step-by-step explanation:
Since you have 4 sides to the pen you will need to figure out how many yard total there is so two of your sides are 9 yards and the other two are 18 yards. now you have to add however many yards there are....
9+9=18
18+18=36
then you have to add those two numbers together
18+36=54 yards total
now you just multiply 54 by 8.98
your total amount of money you spent is $484.92
Which inequality is equivalent to −4t≥28?
Answer:
The first answer = t ≥-7
Step-by-step explanation:
If one side of an inequality is multiplied by a negative number, to find an equivalent inequality the “direction” of the inequality has to change (for example, ≥ has to change to ≤ ). Find a so that y > x is equivalent to − 3 y < a x.
