Answer: 8+9

Step-by-step explanation:

Jina made 6 identical necklaces, each having beads and a pendant. The total cost of the beads and pendants for all 6 necklaces was $33.60. If the beads cost a
total of $14.40, how much did each pendant cost?

Answers

Answer:

$3.215

Step-by-step explanation:

Total cost of the beads and pendants = $33.60

Total number of necklaces = 6

Cost of beads = $14.40

To find : cost of each pendant.

Total cost of pendants = $33.69 - $14.40

= $19.29

Now, cost of each pendant = $19.29/6

= $3.215

Josh and Ben spotted a bear in the woods while riding their bikes. Josh rode 3 miles north and Ben rode 2 miles east.

How far apart are the two boys?

Round to the nearest tenth if needed.

Answers

Answer:

3.6 miles

Step-by-step explanation:

a²+b²=c²

a and b are triangle legs, and for this question it doesn't really matter which you identify as a or b. We are looking for c, or the distance apart from each other.

3²+2²=c²

= 9+4=c²

= 9+4= 13

= c² = 13

Now we are looking for the square root of 13

√13 = 3.605...

This rounded to the nearest tenth is 3.6

The answer is 3.6 miles.

Hope this helped and made it a bit easier to understand - sorry if the text format is a little messy.

Josh and Ben are 3.6 miles apart from each other.

The distance covered by Josh north, distance covered by Ben east and the distance between the two boys forms a right angled triangle.

Let x represent the distance between the two boys.

Using Pythagoras theorem:

x² = 3² + 2²

x² = 9 + 4

x² = 13

x = 3.6 miles

Therefore both Josh and Ben are 3.6 miles apart from each other.

Step-by-step explanation:

Given

Rule: Divide by 2

[tex]800, 400, 200, 100, [\ ], [\ ][/tex]

See attachment for complete question

Required

Which statement is true

First, we apply the rule to complete the blanks.

Divide by 2 implies that we divide the current element by 2, to get the next

So, the first blank becomes

[tex][\ ] = \frac{100}{2} = 50[/tex]

The next is:

[tex][\ ] = \frac{50}{2} = 25[/tex]

So, we have:

[tex]800, 400, 200, 100, 50, 25[/tex]

Compare each option with the above dataset, we have:

(a) False; because 25 do not have 0 in its 1's space

(b) False; because 50 and 25 do not have 0 in their 10's space

(c) True; because each of the dataset either have 0 or 5 in their 1's space
