The fastest method would be to add 8+5 and then divide 390 by it. And then that would be your base unit which you multiply to 8 and 5 to get your answers

8+5=13
390/13
30
30x8=240 adults
30x5=150 children

Hiii dont mind the answer that i put but im not sure if im right, can someone please help me?
AVprozaik [17]

Answer:

Option 4

Step-by-step explanation:

The volume of a cylinder is going to be the area of the base (which is a circle) times the height. if you have cylindrical mug, then you can use the base area×height relationship, but it won't be exact because some of the volume is going to be used for the walls of the mug itself.

Anyways:

Volume = Base Area × Height

•Base Area -> Circle = π×radius²

•Height is given as 7in.

Volume = π×(6.2in)² × 7in = 845.33975...

Volume is in units cubed (the 3rd power) which is where the in³ is from. Your closest option here looks to be the 4th choice.

The ratio of girls to boys in Mr. Smith's homeroom is 3:4. The ratio in Mr. Smith's homeroom to students in the whole 7th grade
Leno4ka [110]

3:4 = G:B

1:5 = Mr. Smith's class: 7th Grade

2:7= 7th: Middle school

12 girls = 3 units

1 unit = 12/3= 4

Boys = 4x4= 16

<em>Whole class = 28 students</em>

Class : Grade = 1:5     <em> 7 = number of units in  Mr. Smith's class</em>

28 = 1 unit

5 units= 28x5= 140 <em>There are 140 kids in the grade</em>

140 = 2 units

1 unit = 140/2= 70

70x7=490

<u><em>There are 490 students in the whole grade</em></u>

Each carton of eggs cost $3 make a table and an equation
dolphi86 [110]

Answer:

y = 3x

Step-by-step explanation:

x is number of cartons of eggs

y is cost

cost increases by 3 for every carton of eggs, so slope is 3

x and y intercepts are zero because there is no cost when there are no eggs

equation: y = 3x
