Answer:
905
Step-by-step explanation:
arithmetic sequence are in form
a(n)=a(0)+d(n-1)
a(0)=25
common difference: d=35-25=10
a(n)=25+10(n-1)
a(89)=25+10(88)=905
Answer:
12
Step-by-step explanation:
2 : 6 pencil : eraser
? : 36
36 divided 6 = 6
so to get to the unknown value u multiply 2 x 6
which equals 12
1.5 pages her friend can read so the formula would be
1.5x and x being the number of pages her friend reads
1.5 times 20 is not 25 it's 30
therefore no Aileen's mom is not correct
The length of side DE is 3cm
<h2 /><h3>Parallel line</h3>
Since the line AC is equivalent to DE, hence AC = DE
To get the length of DE, we will need to get the length oF AC using the Pythagoras theorem:
Given the following parameters
Hypotenuse = 5
Opposite = 4
Required
Adjacent side
Substitute the given parameters into the formula of Pythagoras theorem.
AC² = 5² - 4²
AC² = 25 - 16
AC² = 9
AC = 3
Hence the length of side DE is 3cm
