1 answer:

6 0

Answer

0

Explanation

Formula for sum of interior angles:

(n - 2) • 180 = sum = 2205 °

Where n = number of sides

2205/180 = n - 2

12.25 = n - 2

14.25 = n

Answer is 0 as you can’t have a quarter of a side

PLEASEE HELPPP!!!

Harlamova29_29 [7]

Answer:

The amount is $649.46 and the interest is $49.46.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A=P(1+rn)n⋅t

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

In this example we have

P=$600 , r=8% , n=4 and t=1 years

After plugging the given information we have

AAAA=600(1+0.084)4⋅1=600⋅1.024=600⋅1.082432=649.46

STEP 2: To find interest we use formula A=P+I, since A=649.46 and P = 600 we have:

A649.46II=P+I=600+I=649.46−600=49.46

MAVERICK [17]

Answer:

area of triangle = 4.5*6/2 = 13.5 sq.yd.

Step-by-step explanation:

The area of a right triangle is half of the product of the sides adjacent to the right angle.

Here the sides adjacent to the right angle are 6 yd and 4.5 yd.

Therefore the

area of triangle = 4.5*6/2 = 13.5 sq.yd.

Brianna and Ava go to the movie theater and purchase refreshments for their friends. Brianna spends a total of $39.00 on 2 bags

kirill [66]

Answer:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Price of one drink is $9.25

Step-by-step explanation:

Let the price of a bag of popcorn be p.

Let the price of a drink be d.

Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. This implies that:

2p + 2d = 39 ____________(1)

Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. This implies that:

8p + 10d = 174.50 _________(2)

We now have two system of equations which we can use to find the price of a bag of popcorn and drink:

2p + 2d = 39 ____________(1)

8p + 10d = 174.50 _________(2)

Multiply (1) by 4 subtract from (2):

8p + 10d = 174.50 _______(2)

-<u> 8p + 8d = 156 </u> __________(1)

2d = 18.50

=> d = $9.25

The price of one drink is $9.25
