The price of one hot dog was $1.65
<u>Step-by-step explanation:</u>
Given that each of the four brothers bought two hotdogs and a packet of chips each.
Total number of hotdogs they bought=4*2 =8
Total bags of chips they bought= 4
price of a bag of chips=$1.25
Total price of items=$18.2
let the price of a hotdog=x
then
8x+5=18.2
8x=18.2-5
8x=13.2
x=13.2/8
=1.65
The price of one hotdog=$1.65
Answer:
35°
Step-by-step explanation:
From the sketch made, to obtain B we use the cosine angle formula :
We have 2 so des and an included angle
Cos B = (a² + c² - b²) / 2ac
First we obtain the side c
c² = a² + b² - 2ab CosC
c² = 11.2² + 6.7² - 2(11.7 * 6.7) * cos 72
c = 11.13
Using the value of c
Cos B = (a² + c² - b²) / 2ac
CosB = (11.2² + 11.13² - 6.7²) / (2*11.2*11.13)
Cos B = 204.4269 / 249.312
B = Cos^-1(204.4269 / 249.312)
B = 34.9°
