Answer:
x = 13 and y = 13√3
Step-by-step explanation:
Recall that sin Ф = opposite side / hypotenuse, and that
cos Ф = adjacent sice / hypotenuse.
if we recognize that the angle Ф is 30° here, then we know that:
x = opposite side = hypotenuse * sin 30° = 26*(1/2) = 13.
and....
y = adjacent side = hypotenuse*cos 30° = 26*√3/2 = 13√3
In summary, x = 13 and y = 13√3
Answer:
$74.75
Step-by-step explanation:
When it comes to tax, the sales tax is applied <em>after</em> the discount is provided by the store, as long as it is something like a direct store coupon or a discounted price. In this case, it is a discounted price by the store, so we will include sales tax after.
$79.20 after a 12% discount becomes $69.70 (or $69.696).
The state tax applies to this new price.
7.25% of $69.70 is $74.75
Answer:
b is the right answer
Step-by-step explanation:
because the ratio of 98÷10=9.8
when we did the ration of 1078÷110=9.8
we can say that both ratio is same.
It is decay, growth would mean that the number in brackets is greater than 1.
