Mathematics

Margarita [4]3 years ago

Every 56 seconds, the radioactive substance is divided in half.

224 / 56 = 4

We need to cut the substance in half 4 times.

896 / 2 = 448

448 / 2 = 224

224 / 2 = 112

112 / 2 = 56

After 224 seconds, there will be 56 grams of the radioactive substance left over

Answer:

56 grams

Step-by-step explanation:

To get how much a HALF-life is, divide the amount by two getting one half of the original amount. That represents on half-life. so 224= 56 x 4

remember the half-life is fifty-six, so there would be 4 half-lives within 224 seconds. Divide 896 by 2 (448) then again divide by 2 (224) divide by 2 again (112) and again divide by 2 and you would get 56 grams.

In hopes of encouraging healthier snacks at school, Zack brought in a tray of carrot sticks and apple slices to share. The tray
Alex787 [66]

Answer:

48% were carrot sticks.

52% were apple slices.

Step-by-step explanation:

Given that:

Total number of snacks in the tray = 25

Number of carrot sticks = 12

Number of apple slices = 25 - 12 = 13

Percent of carrot sticks = \frac{Number\ of\ carrot\ sticks}{Total\ Number}*100

Percent of carrot sticks= \frac{12}{25}*100

Percent of carrot sticks = 0.48 * 100 = 48%

Percent of apple slices = \frac{13}{25}*100

Percent of apple slices = 52%

Hence,

48% were carrot sticks.

52% were apple slices.

Paul [167]

Given:

Anju cut square of tin, of edge 3.7 cm, from a larger square of edge 6.3 cm.

To find:

The area of the remaining tin.

Solution:

Area of a square is:

Area=a^2

Where, a is the edge of the square.

Area of the smaller square is:

A_1=(3.7)^2

A_1=13.69

Area of the larger square is:

A_2=(6.3)^2

A_2=39.69

The area of the remaining tin is:

A=A_2-A_1

A=39.69-13.69

A=26

Therefore, the area of the remaining tin is 26 sq. cm.
