Answer:
(0.75) to the 3rd power is 0.421875
then multiply that by 240 and you get 101.25
rounded to the nearest 10th would be 101.3
Step-by-step explanation:
You have to turn the percent into a decimal to do the math.
80 * .40 = 32 (That's the discount.) Now we subtract the orginal price from this.
80 - 32 = 48
Now we need to find the tax value.
48 (our new price) * .0675 = $3.24
Add this back onto the price to get our final price.
3.24 + 48 = $51.24
Will multiple the exponents and the answer x^4
9514 1404 393
Answer:
cos(x) = 0.6
Step-by-step explanation:
First, we need to find UQ.
UQ = UP·cos(y°) = UP·√(1 -sin²(y°)) = (26 cm)√(1 -25/169) = (26 cm)(12/13)
UQ = 24 cm
Then TQ is ...
TQ = 1/3UQ = 1/3(24 cm) = 8 cm
And cos(x°) is ...
cos(x°) = √(1 -sin²(x)) = √(1 -64/100)
cos(x°) = 6/10 = 3/5
cos(x°) = 3/5 = 0.6
