Answer:

Step-by-step explanation:

Triangle HIJ is a right angle triangle.

From the given right angle triangle

IJ represents the hypotenuse of the right angle triangle.

With ∠J as the reference angle,

HJ represents the adjacent side of the right angle triangle.

HI represents the opposite side of the right angle triangle.

To determine IJ, we would apply Sine trigonometric ratio. It is expressed as

Sin θ = opposite side/hypotenuse. Therefore,

Sin 54 = 7/IJ

0.8090 = 7/IJ

IJ = 7/0.8090

IJ = 8.7 to the nearest tenth

Micah pays 54$ for an item originally priced 60$. What percentage of the original price was his discount?

pantera1 [17]

Answer: The percentage of the original price was his discount = 10%

Step-by-step explanation:

Given: original price = $60

Price after discount = $54

Discount = Price after discount - original price

= $ (60-54) = $6

The percentage of the original price was his discount = $\dfrac{Discount}{Original\ price}\times100$

$=\dfrac{6}{60}\times100\%\\\\=\dfrac{1}{10}\times100\%\\\\=10\%$

Hence, the percentage of the original price was his discount = 10%

Answer:

3rd choice

Step-by-step explanation:

(7y^6)(2y^-4)^2

= (7y^6)(4y^-8)

Calculate:

(7y^6) * (4y^-8)

Is the sequence below is arithmetic {1, 8, 27,64}

Rzqust [24]

Answer:

Step-by-step explanation:

No, because 8 - 1 ≠ 27 - 8. So, there is no common difference which is needed in order for the sequence to be arithmetic

How do you simplify this problem?

Yuri [45]

1+tan^2(x) = sec^2(x)

sec^2(x) = 1/cos^2(x)

csc(-x) / 1/cos^2(x) =

cos^2(x) csc(-x)
