Step-by-step explanation:

14 ÷ 2 = 7 ← value of 1 part of the ratio, thus there are 7 blue marbles

Total marbles = 14 + 7 = 21

20 balloons have to be devided between a group A and Group B in the ratio 2:3. How many balloons will each group receive?

AVprozaik [17]

Answer:

There are 8 and 12 balloons for groups A and B, respectively.

Step-by-step explanation:

The ratio 2 : 3 means that there are 2 balloons in group A for each 3 balloons in the group B. The amounts of balloons asigned to each groups are determined by the following formulas:

Group A

$n_{A} = \frac{2}{2+3}\cdot (20)$

$n_{A} = 8$

Group B

$n_{B} = \frac{3}{2+3}\cdot (20)$

$n_{B} = 12$

There are 8 and 12 balloons for groups A and B, respectively.

Answer:

117

Step-by-step explanation:

Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)

a²+b²=c²

A= 75

B= 90

C is always the hypotenuse.

75²+90²= c²

5,625+8,100= 13,725

√13,725= 117.15374513859981591194584103639

To the nearest whole number: 117

To the nearest tenth: 117.2
