sin 45 = opp/hyp
sin 45 = 4 / y
y = 4/sin 45
y = 4 /((sqrt2)/2)=4* sqrt(2)
tan 45 =opp/adj
tan 45 = 4/(x-3)
1 = 4/(x-3)
x-3 = 4
x=7
B
Answer:
Step-by-step explanation:
you can go to a calculator
We are given the cost of the product along with the markup percentage. The markup is how the store makes a profit. To figure out the markup price, simply multiply the "cost to store" by 100% plus the markup percent.
So the markup prices per store is:
A = 162 * 1.4 = $226.80
B = 155 * 1.3 = $201.50
C = 160 * 1.25 = $200.00
Clearly, the best deal is store C. So in order to choose store A, we want to pay less than the price of Store C, $200. So if Store A cost $199.99, then we would purchase there instead of Store C.
Therefore, $226.80 - $199.99 = $26.81
If Store A offered a discount of $26.81, we would purchase from Store A.
$26.81/$226.80 = 0.1182
So we would need a discount of 11.82% from Store A.
Answer: 5.1
Step-by-step explanation:
pythagorean theorem: a^2+b^2=c^2
c^2-b^2=a^2 (switch around some things)
(14.9)^2 - (14)^2 = x^2 (insert values) c=14.9,b=14,a=x
222.01 - 196 = x^2
26.01 = x^2
5.1 = x
Not Sure if this is correct but 4^2-5x2^3 = 16-40x
