Answer:

40/41

Step-by-step explanation:

Tangent is opposite over adjacent, and sine is opposite over hypotenuse.  We can find hypotenuse from Pythagorean, which gets us 41 as the hypotenuse.  Therefore sin b = 40/41.

Lisa is buying a computer for $1,500. The sales tax rate is 8.5%. Which expression should be used to calculate t, the total cost
Sveta_85 [38]

Answer:

<h3>t=$1627.5</h3>

Step-by-step explanation:

Step one:

given data

price of computer= $1500

sales tax= 8.5%

Step two

Let us compute the amount in tax

tax= 8.5/100*1500

=0.085*1500

=$127.5

Let the total cost be t

hence

t=1500+0.085*1500

t=1500+127.5

t=$1627.5

What is the value of x.
Gemiola [76]

Answer: 46 degrees

Step-by-step explanation: First you need to find the value of the vertical angle which is 180-(85+53) which is 42 degrees. Since vertical angles are congruent, you can say that 180-(42+92) is equal to x. When you solve it, you get x=46 which is your answer

Answer:

Finding the product of 9, 10 and 9 ; 810

Step-by-step explanation:

Given that :

Length = 10 feets

Width = 9 feets

Height = 9 feets

The volume of a rectangular prism is obtained by :

Length * width * height

The volume could be obtained by taking the product of 10, 9 and 9

Hence, the volume of the rectangular prism is :

(10 * 9 * 9) feet³ = 810 feet³

Number of 1 feet³ boxes = 810 feet³ / 1 feet³ = 810
