Answer:
y=13/3x-1
Step-by-step explanation:
k=(y2-y1) /(x2-x1)
A(0,-1) x1=0,y1=-1
B(3,12) x2=3, y2=12
k=(12-(-1))/(3-0)
k=(12+1)/3
k=13/3
y-y1=k(x-x1)
y-(-1)=13/3(x-0)
y+1=13/3*x
y=13/3*x-1
Eddie orders a pizza in each person gets 3/5 first you divided 3/5 you get 6 then you divide 8 by you you won't get a whole number the answer will be like = 13.333.
examples would look like this.
(3/5)*x=8
(8*5/3)= x
your answer is 13 people are at the party.
also they would be 1.5 slices of pizza left over.
Answer: The common denominator for:
4/6 =12
7/12= 84
9/24=72
7/8= 56
Hope you have a nice day/night :)
Answer:
6.55 cm
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. Types of triangles are isosceles, acute, scalene, obtuse, right and equilateral triangle.
Cosine rule is used to show the relationship between sides and angles of a triangle. If a, b, and c are sides of a triangle, while A, B, and C are angles opposite to the corresponding sides. Then:
c² = a² + b² - 2ab*cos(C)
Given that PR = 13 cm, PQ = 12 cm and angle QPR = 30°, hence:
QR² = PR² + PQ² - 2(PR)(PQ)cos(∠QPR)
QR² = 13² + 12² - 2(13)(12)cos(30) = 169 + 144 - 270
QR² = 43
QR = 6.55 cm
The 'yellow region' seems to be a square. The area of a square is the length of the side raised to the second power. In this case it's
![5^{2}](https://tex.z-dn.net/?f=%205%5E%7B2%7D%20)
.
The area for the yellow region is 25(
