A^2 + b^2 = c^2
9^2 + 12^2 = 225
square root of 225 is 15
It's kind of not C.
Solve this proportion for 'x':
3/50 = x/2400
Hint: Cross-multiply the proportion, then do what you need to do.
Answer:
31465 ways
Step-by-step explanation:
Given data
Let us apply the combination formula
nCr = n! / r! * (n - r)!
n= 31
r= 4
substitute
= 31!/4!(31-4)!
= 31!/4!(27)!
= 31*30*29*28*27!/ 4!(27)!
= 31*30*29*28/4!
=31*30*29*28/4*3*2*1
=755160/24
=31465 ways
Hence there are 31465 possible ways to rank it

Answer:
a. 0.81
b. v = 28000(0.81^n)
c. 2757.36
Step-by-step explanation:
a. The growth factor is 1 more than the growth rate. Here, the growth rate is -19% (per year), so the growth factor, the multiplier, is ...
1 -0.19 = 0.81
__
b. The equation sets value equal to the original value multiplied by the growth factor to the power of the number of years:
value = (original value) × (growth factor)^n
v = 28000(0.81^n)
__
c. For n=11, this is ...
v = 28000(0.81^11) ≈ 2757.36
The value of the truck after 11 years is about $2757.
Answer:
<h2>$1380.2</h2>
Step-by-step explanation:
Step one:
given data
weekly earnings= $375
Commission is 4% of sales.= 0.4
supposing sale is x, and the total earning is y
the expression for the total earning will be
y=375+0.4x
Step two:
for x= 2513, y will be
y=375+0.4(2513)
y=375+1005.2
y=1380.2
<em><u>Hence her total earnings for the week will be $1380.2</u></em>
