The number of friends represents how many had the type of ice cream. It is the number of friends.
Answer:
volume= length × width × height
7×5×11
35×11
385cm³
<span>V(o) = 1/3 πr²h - old volume
</span>V(n) = 1/3 π(2r)²(h/2)=1/3 π(2r)²(h/2)=1/3*4/2* πr²h=1/3*2* πr²h
V(n)/V(o)=1/3*2* πr²h/1/3 πr²h=2/1
V(n)/V(o)=2/1 - ratio
the volume will be doubled
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
Answer:
2(2x+5) (x+1) = 2(x+1)(2x+5)
Step-by-step explanation:
4x^2 +14x+10
Factor out the 2
2(2x^2 +7x+5)
2(2x+5) (x+1)
You need to keep the 2 that you factored out
2(2x+5) (x+1) = 2(x+1)(2x+5) by the Commutative Property of Multiplication
