Answer:
3 shirts, 6 shorts
Step-by-step explanation:
A total of $264 is spent during shopping on shirts and shorts
Each shirt costs $24
Each shorts cost $32
Therefore the quantity of shirts and shorts bought can be calculated as follows
24× 3= 72
32×6= 192
192+72= 264
Hence 3 shirts and 6 shorts were bought
Answer:
a) distance from plane to swimmer = 2127.66 m
b) distance from swimmer to point D = 1928.31 m
Step-by-step explanation:
Given the question,
height at which the plane is = 900m
angle of depression = 25°
If we closely observe, the whole scene is making an right angle triangle
So, we can use trigonometry identities
<h3>a)</h3><h3>cosФ = BD / AB</h3>
cos (90-25) = 900 / AB
0.423 = 900 /AB
AB = 2127.66 m
<h3>b)</h3><h3>sinФ = AD/AB</h3>
sin(90-25) = AD /2127.66
AD = sin(90-25) x 2127.66
AD = 1928.31m

Step-by-step explanation:
Answer:
y= 407.54654 ft
Step-by-step explanation:
This is an exponential decay functions
y = ab^x where a is the initial value and b is ( 1 - rate of decay)
a = 520
b = 1- 3%
y = 520 ( 1- .3) ^x
y = 520 ( .97) ^x
We want x to be 8 weeks
y = 520 ( .97) ^8
y= 407.54654 ft
The common difference on the sequence is -3 and the number of books will be 21.
<h3>How to illustrate the sequence?</h3>
The formula that can be used to calculate the number of books will be:
= a + (n - 1)d
= 57 + (13 - 1)-
= 57 + (12 × -3)
= 57 - 36
= 21
Also, from the information given, each row has three fewer books than the row below it. Therefore, the common difference is -3.
