Answer:the number of medium packs is 4

the number of large packs is 6

Step-by-step explanation:

Let x represent the number of medium packs that she bought.

Let y represent the number of large packs that she bought.

Ivy has 10 packs of cup for her holiday party. This means that

x + y = 10

a pack of medium cups costs 1.80 and a pack of large cups costs 2.40 she paid a total of 21.60. This means that

1.8x + 2.4y = 21.60 - - - - - - - - 1

Substituting x = 10 - y into equation 1, it becomes

1.8(10 - y) + 2.4y = 21.60

18 - 1.8y + 2.4y = 21.6

- 1.8y + 2.4y = 21.6 - 18

0.6y = 3.6

y = 3.6/0.6 = 6

Substituting y = 0.6 into x = 10 - y, it becomes

x = 10 - 6 = 4

Answer:

Medium: 4 and Large: 6

Step-by-step explanation:

Factor pairs that are equivalent to 10:

1,9

2,8

3,7

4,6

5,5

and so on. So you could do 2.4*9 and 1.8*1. If that doesn't work, switch it around. This coud probably take 1/2 of a hour or more. But it'll be worth it if it's a grade. :3

In the end, I'm pretty sure you should be able to get the answer:

Medium cups: 4

Large cups: 6

1.8 multiplied by 4 would get you 7.2 and 2.4 multiplied by 6 would get you 14.4. If you add them all up, you would get a 21.6! If you didn't, check your math again.

ludmilkaskok [199]

Answer:

11  feet away.

Step-by-step explanation:

Given:

A water and sprinkle our sins water out in a circular pattern

Area formed by the watering pattern is 379.94 square feet

To find:

How many feet away can it spread water means we have to find distance from the middle point to the last end of circular pattern of water sprinkling (radius of a circle) = ?

solution:

By using ,Area of a circle = \pi r^{2}

Area of a circle = 379.94 square feet  (given)

\pi r^{2} = 379.94

3.14\times r^{2}  = 379.94\\

Dividing both side by 3.14

r^{2}  = \frac{379.94}{3.14}  = 121

Taking square root both side

r = \sqrt[2]{11\times11}        (Taking common)

r = 11

Therefore, radius = 11

Thus,  it can  spread water 11  feet away.

KengaRu [80]

Complete question :

la distancia entre la tierra y la luna es de 384 392 km. Los astronautas de la Apolo XL salieron el 16 de julio de 1969 desde el Centro Espacial Kennedy y al alcanzaron la orbita el 19 de julio de 1969. Suponiendo que cada dia recorrieron la misma cantidad de kilometros cuantos kilometros recorrieron por dia

Responder:

128130,66 kilometros

Explicación paso a paso:

Dado que:

Distancia entre la tierra y la luna = 384,392 km

Tiempo empleado = (19 de julio - 16 de julio) mismo año = 3 días

Velocidad = distancia / tiempo

El tiempo empleado es (3 * 24) = 72 horas

Por lo tanto,

velocidad = 384,392 / 72

= 5338,7777 kilómetros por hora

Dado que se supone que la distancia recorrida diariamente es la misma m:

El número de kilómetros recorridos por día:

5338,7777 kilómetros por hora * 24

= 128130,66 kilometros
