nasty-shy [4]

Hwong could fill 12 packets of coffee in small boxes:

He has 10 boxes, so 10 x 12 = 120 packets total

Hwong's packets of coffee in the large boxes:

He can fit 50 packets into the boxes, so 120/50 = 2 large boxes and a remaining 20 packets of coffee

Therefore, Hwong can fit 12 packets of coffee to 1 small box and 8 packets to the other small box

A person plans to invest a total of $3500 in one bank account at 2.2% annual interest and another bank account at 17% annual int

jeka57 [31]

Answer:

$435.3

Step-by-step explanation:

Assuming simple interest

Interest, I=Pi/100 where P is principal amount and i is rate of interest in percentage

For $3500, the interest will be 3500*2.2/100=$77

From total target of $151, the person is less 151-77=$74

Taking x as principal and rate of interest as 17% then

0.17x=74

X=74/0.17=$435.2941176470

Rounded off as $435.3

tim and his brother are building towers out of blocks. Tim is using blue blocks that are 6 cm tall and his brother is using gree

Karolina [17]

The shortest possible height of tower is 24 cm.

Tim used 4 blue blocks and his brother used 3 green blocks.

Step-by-step explanation:

Given,

Height of blue block = 6 cm

Height of green block = 8 cm

We will take least common multiple to find the shortest possible height.

6 = 2*3

8 = 2*2*2

LCM = 2*2*2*3 = 24 cm

The shortest possible height of tower is 24 cm.

Number of blue blocks used = $\frac{24}{6} = 4$

Number of green blocks used = $\frac{24}{8} = 3$

Tim used 4 blue blocks and his brother used 3 green blocks.

X divided by 6/7 = 3 and 2/5

Rom4ik [11]

X / 6/7 is 3 2/5. First, concert the numbers to decimals for simplicity sake, and you get x/.857 = 3.4. Multiply both sides by .857 to get x alone and you get x ≈ 2.9143
