This forms a right angled triangle and Ralph flies down the hypotenuse x,
so using trigonometry:-
sin 59 = 12.4 / x
x = 12.4 / sin 59
= 14.47 feet to nearest hundredth.
Answer:
See solution below
Step-by-step explanation:
Given the expression

Recall that
cos x = sin(90-x)
cos(x+30 ) = sin (90-(x+30)
= sin(90-x-30)
= sin(60-x)
Substitute

6% = 0.06
The total cost of a $12.50 item plus 6% sales tax :
$12.50 * 1.06 = $13.25
Answer
$13.25
Answer:
27.5
Step-by-step explanation:
y = kx
55 = 120k
k = 55/120
y = 55/120 x 60
y = 55/2
y = 27.5
Answer:
Tyrese will receive $39.81 in return.
Step-by-step explanation:
First, you have to multiply the 15 packs for the cost per pack:
15*$5=$75
As there is a 25% discount before tax if 10 or more packs are purchased, you have to calculate 25% of the total cost for the 15 packs and subtract that amount from the cost:
$75*25%=$18.75
$75-$18.75=$56.25
Then, you have to calculate 7% of the amount with the discount and add that to the cost:
$56.25*7%=$3.93
$56.25+$3.94=$60.19
Now, you can subtract $60.19 from $100 to find the change that Tyrese will receive in return:
$100-$60.19= $39.81
According to this, the answer is that Tyrese will receive $39.81 in return.
