Step-by-step explanation:
80+70+2×+×=180
=150+2×+×=180
=150+3×=×180
180-150=3×
30=3×
/3=/3
×=10
Ratio is the comparison of sizes of two quantities of the same unit. Proportions are the equality of two ratios. A/b =c/d
There is only case if ∠c=90
then Δ ACB is right angle triangle.
(hyp)^2=(base)^2+(height)^2
(AB)^2=(15)^2+(17)^2
Answer:
Cell A = 15
Step-by-step explanation:
If 6 spring rolls will serve 3 people, let x be the number of people 30 spring rolls will serve.
Thus,
6 spring rolls = 3 people
30 spring rolls = x
Cross multiply
6*x = 3*30
6x = 90
Divide both sides by 6
6x/6 = 90/6
x = 15
30 spring rolls will serve 15 people.
Each is a collection of points. These four building blocks of geometry, points, lines, planes, and space, form the basis for all of the geometry you will study in this guide. It is important to understand their properties fully.
