Answer: A

Step-by-step explanation:

So we know that to find the area of a triangle you have to multiply the base times the height and divide it by two or multiply it by 1/2.Looking the information given it say that theta is equal to 26 degrees  and the length of a or the hypotenuse is 25 and b which in this case is the base is 32. So the information gives us the base but now we need to find the height.

To find  H we need to apply trigonometry solve for h the height.

As we could see theta which is 26 degrees is opposite the height and we know the hypotenuse length. So using soh cah toh we have to know that the length of h is  going to be using the sin formula opposite over hypotenuse.

sin(26)=\frac{h}{25}    solve for h by multiplying both sides by 25.

h= 25 sin(26)

h= 10.96   is being rounded to the nearest hundredth because that is essential

Now we know H is equal to 10.96  which is the Height so now we have all the information we need the height and the base.

Multiply 10.96 by 32 and divide it by 2.

10.96 * 32 =  350.72

350.72 /2 = 176.36  

The best answer is A  because that is the only best approximation to 175.35.

An online store sells old video games and DVDS as a bundle. A bundle of two video games and three DVDS can be purchased for $89.
irga5000 [103]

Answer:

video game: $29.50

DVD: $10

Step-by-step explanation:

Let d = price of one DVD, and let v = price of 1 video game.

"A bundle of two video games and three DVDS can be purchased for $89.00."

2v + 3d = 89

"A bundle of one video game and two DVDS can be purchased for $49.50."

v + 2d = 49.5

We have two equations in two unknowns, so we can solve them as a system of 2 equations.

2v + 3d = 89

v + 2d = 49.5

Rewrite the first equation.

Multiply both sides of the second equation by -2 and write it below the first equation.

Add the equations.

       2v + 3d = 89

(+)   -2v - 4d = -99

---------------------------

               -d = -10

d = 10

Now we substitute 10 for d in the second original equation and solve for v.

v + 2d = 49.5

v + 2(10) = 49.5

v + 20 = 49.5

v = 29.5

Answer: video game: $29.50; DVD: $10

Mac is 5 feet tall and casts a 4 foot 6 inch shadow. At the same time, a nearby tree casts a 20
Sergio [31]

I will convert feet to inches.

4 feet, 6 inches = 54 inches

20 feet = 240 inches

5/x = 54/240

Let x = closest height of tree

54x = 5(240)

54x = 1,200

x = 1200/54

x = 22.2222222222

The tree is about 22 feet tall.
