Since the triangle has equal sides it will carry onto it self at 120, since it can rotate 360 grades only and it has 3 sides so it will rotate in one third of 360 so 120

i hope i helped you

Answer:

Minimum umber of degrees that an equilateral triangle can be rotated before it carries onto itself = 120°

Step-by-step explanation:

Refer the figure given below.

We need to find angle ADC to get the same equilateral triangle after rotation.

∠ADC = 180 - ( ∠DAC + ∠DCA) = 180 - ∠DAC - ∠DCA

∠DAC = ∠DCA = 0.5 x 60 = 30°

Substituting

 ∠ADC = 180 - 30- 30 = 180 - 60 = 120°

Minimum umber of degrees that an equilateral triangle can be rotated before it carries onto itself = 120°

The price of a bag of candy is a linear function of the amount of candy in the bag. A bag containing 25 pieces costs $0.99 and a
OlgaM077 [116]

Answer:

About 152 pieces of candy

Step-by-step explanation:

Set up equal proportions to solve for the $5.99 bag.

We know that 24 pieces = .99, so

\frac{25 pieces}{.99 dollars} = \frac{x pieces}{5.99 dollars}

Make sure to keep the pieces on top, and the dollars on bottom (or vice versa). If your units are messed up, it will not work.

Cross-multiply.

25(5.99) = .99x

Simplify.

149.75 = .99x

Divide both sides by .99.

x = 151.26 = about 151 pieces of candy

Which of the following is an arithmetic sequence?
alexandr1967 [171]
Answer: Only the second sequence is arithmetic. 

Work:
An arithmetic sequence is a sequence in which there is a common value added or subtracted between each term in the sequence. 
The first option, -2, 4, -6, 8,... is not arithmetic because the terms switch back and forth between positive and negative signs meaning that there is no common value that can be added between each term. 
The second option, -8, -6, -4, -2,... is arithmetic because there is a common difference between each term which is +2.
The third option, 2, 4, 8, 16,... is not arithmetic but is, in fact, geometric. There is no common value that is added or subtracted between each term.
