The base of a triangle is 4 cm greater than the

Anna35 [415]

Answer:

Step-by-step explanation:

Formula for area of a triangle:

Height x Base /2

Base (b) = h +4

Height = h

h + 4 x h /2 = 30cm

=> h +4 x h = 60

=> h+4h =60

=> 5h = 60

=> h = 12

Height = 12

Base = 12 +4 = 16

If a sequence contains only whole numbers, which of these sequences could include the term 27?

erik [133]

Depending on the first term, the sequences
$a_n=2a_{n-1}+1
\\
\\a_n=3a_{n-1}
\\
\\a_n=a_{n-1}+6$
would work.

If the sequence began at 6,
$a_n=2a_{n-1}+1=6, 13, 27, ...$

If the sequence began at 1,
$a_n=3a_{n-1}=1, 3, 9, 27, ...$

If the sequence began at 3,
$a_n=a_{n-1}+6=3, 9, 15, 21, 27, ...$

shania wants to measure the capacity of her bathroom sink. Circle the unit of measurement she should use to measure its capacity

qaws [65]

Pounds because I don't think that a sink weighs a ton and ounces would be far to complex. Plus, you are measuring the capacity of a sink... Sorry if the answer sucks! I'm new at this and not all that smart...
