Answer:
there are 3 ferrets,15 dogs,27 cats
Step-by-step explanation:
the ratio of the three
9:5:1
the ferrets,1/15 * 45= 3
the dogs,5/15 * 45= 15
the cats, 9/15 * 45=27
Answer:
Step-by-step explanation:
The given sequence is 22, 20, 18, ...
We need to find the explicit formula for an.
First term is 22
Second term = 20
Third term = 18
We can write the formula as :
Where
a is 22
d is common difference = 20-22 = -2
Forth term will be :
Hence, the formula is .
Answer:
true
Step-by-step explanation:
use the pythagorean theorem
Sarah sold 66 posters
<em><u>Solution:</u></em>
Let "a" be the number of shirts sold
Let "b" be the number of posters sold
<em><u>Sarah sold a total of 178 t shirts and posters at a festival</u></em>
Therefore,
number of shirts sold + number of posters sold = 178
a + b = 178 ----------- eqn 1
<em><u>She sold 46 more tshirts than poster</u></em>
Number of shirts sold = 46 + number of posters sold
a = 46 + b --------- eqn 2
<em><u>Substitute eqn 2 in eqn 1</u></em>
46 + b + b = 178
2b = 178 - 46
2b = 132
b = 66
Thus she sold 66 posters
