Answer:
16.875 spiders
Step-by-step explanation:
Given
Let
So, we have:
--- equal amounts
--- the legs
Required
The number of spider
Since she has an equal amount of B, C and S;
The expression can be written as:
Solve for S
<em>The result of the solution does not represent real life situation because it it is not possible to have a fraction number of spider</em>
Answer:
Substitution
Step-by-step explanation:
tbh i havent checked so sorry if its wrong
Answer:
B
Step-by-step explanation:
Using the Sine Rule in ΔABC
= 
= 
∠C = 180° - (82 + 58)° = 180° - 140° = 40°
Completing values in the above formula gives
= 
= 
We require a pair of ratios which contain b and 3 known quantities, that is
=
OR
= 
→ B
Well you never sent a picture but the most logical answer is 80 cm
Answer:
an=1*2.5^(n-1)
=2.5^(n-1)
Step-by-step explanation:
Complete question below:
What value, written as a decimal, should Lena use as the common ratio? Lena is asked to write an explicit formula for the graphed geometric sequence. On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 2.5), (3, 6.25).
Solution
Point (1, 1), (2, 2.5), (3, 6.25).
a=1
ar=2.5
ar^2=6.25
From ar and ar^2
r=6.25/2.5
=2.5
r=2.5
an=ar^(n-1)
Therefore, the explicit formula is
an=1*2.5^(n-1)
=2.5^(n-1)
