Answer:

0.29

Step-by-step explanation:

14.50 divided by 50 = 0.29

(use standard algorithm)

If 50 disks cost 14.50, 1 disk would cost 0.29 if we divide them up.

Therefore, 0.29 would be your answer.

Hope this helps! Good Luck!

What is the equation of the line in standard form?<br> 3x−y=−6 3x + y = 6 x + 6y = 9 x−6y=−9
lisabon 2012 [21]

The standard form: Ax + By = C

3x - y = -6  YES - A = 3, B = -1, C = -6

3x + y = 6   YES - A = 3, B = 1, C = 6

x + 6y = 9   YES - A = 1, B = 6, C = 9

x - 6y = -9   YES - A = 1, B = -6, C = -9

Can someone help me with this one ??
s344n2d4d5 [400]

Answer:

Measure angle B = 65 degrees    AB = 34        AC = 30

Step-by-step explanation:

Triangle Sum Theorem: 180 - 90 - 25 = 90 + 25 + 65 = 180

Tangent 25 = 16/x

AB = 34

Pythagorean Theorem Equation:

b =[]\sqrt{34^{2} - 16^{2}}= \sqrt{900}= 30

AC = 30

PLEASE HELP!! WILL GIVE Points Using the known angle, what side is known? What side is unknown? Use opposite, adjacent, or hypot
ruslelena [56]

4.

known side: opposite (150m)

unknown sides: adjacent and hypotenuse

using Tan to find the distance from the tower's base to the key.

why do we use Tan to find the distance?

the tower creates an angle of 72 degrees with the ground, which will be called α, and it is 150m high from the ground which is opposite ∠α. (shown in picture). we can see that the distance from the base of the tower to the key is the adjacent of the ∠α.

Tan α =  opposite / adjacent

=> Tan 72° = 150 / x

=> x = 150 / Tan 72°

=> x = 48.73795443 m = ~48.7m

5.

4.

known side: opposite (150m)

unknown sides: adjacent and hypotenuse

using Sin to find the distance that the ant travelled.

why do we use Sinn to find the distance?

the tower creates an angle of 72 degrees with the ground, which will be called α, and it is 150m high from the ground which is opposite ∠α. (shown in picture). the ant travelled along the tower's body, which is the hypotenuse of the triangle, from the top until reaching the ground.

Sin α =  opposite / hypotenuse

=> Sin 72° = 150 / x

=> x = 150 / Sin 72°

=> x = 157.7193336 m = ~157.7m

6.

(using unrounded numbers to calculate because there is a small difference in results if using the rounded numbers)

c^2 = a^2 + b^2 (pythago)

157.7^2 = 150^2 + 48.7^2

24875.3882 = 24875.3882 (correct)

Someone please help with these and explain your answer for both!!! I will give brainliest if correct!!!
goldenfox [79]

Answer:

C

Step-by-step explanation:

We have congruent angles in the middle and 2 sides are congruent as well which makes (Angle-Side-Side) which doesn't work for congruent triangles.
