Answer:
18
Step-by-step explanation:
Multiply 20 by 0.90 (that is 90%)
18 is the answer
Hope this helps :)
Answer: C
The formula for tangent is tan(x)= opposite/ adjacent so plugging it in would be tan(x)=9/4
Chapter : Algebra
Study : Math in Junior high school
x = 7 + √40
find √x of √x + 1
= √x + 1
= √(7+√40) + 1
in Formula is :
= √7+√40 = √x + √y
= (√7+√40)² = (√x + √y)²
= 7+√40 = x + 2√xy + y
= 7 + √40 = x + y + 2√xy
→ 7 = x + y → y = 7 - x ... Equation 1
→ √40 = 2√xy → √40 = 2.2√10 = 4√10
= xy = 10 ... Equation 2
substitution Equation 1 to 2 :
= xy = 10
= x(7-x) = 10
= 7x - x² = 10
= x² - 7x + 10 = 0
= (x - 5)(x - 2) = 0
= x = 5 or x = 2
Subsitution x = 5 and x = 2, to equation 1
#For x = 5
= y = 7 - x
= y = 7 - (5)
= y = 2
#For x = 2
= y = 7 - x
= y = 7 - (2)
= y = 5
and his x and y was find :
#Equation 1 :
= x = 5 and y = 2
#Equation 2 :
= x = 2 and y = 5
So that :
√7+√40 = √x + √y
= √7+√40 = √2 + √5
And that is answer of question :
= √2 + √5 + 1
The total cost of the lease is $18,092.30.
<h3>What is the total cost of the lease?</h3>
The total cost of the lease is a function of the up front fee, payment per month and the total cost for miles over 36,000.
Total cost = $3500 + (384 x 12 x 3) + [0.15 x (41,122 - 36,000)]
$3500 + 13,824 + 768.30 = $18,092.30
