First of all that is definately not a square ehahah but okay a square has equal sides so the left and right also = 10 and an isosceles trapizoid has its islands equal as well so the other side is. =5
All sides are 4+5+5+10+10+10 now add
9+5+10+10+10
14+10+10+10
24+10+10
34+10= 44in

Opal wanted to make some necklaces and sell them at a craft store. She made 37 necklaces and each necklace had somewhere between

alexandr402 [8]

<h3>The total number of beads used in making 37 necklaces is between 2,664 beads and 2,849 beads.</h3>

Step-by-step explanation:

Here, as given: The number of necklace made by Opal = 37

The least number of bead used in each necklace = 72

So, if each necklace is made using the least number of beads then,

The total number of beads used in 37 necklace = 37 x ( beads in 1 necklace)

= 37 x 72 = 2,664 beads

So, the least number of total beads used in 37 necklaces = 2,664 beads

The highest number of bead used in each necklace = 77

So, if each necklace is made using the highest number of beads then,

The total number of beads used in 37 necklace = 37 x ( beads in 1 necklace)

= 37 x 77 = 2,849 beads

So, if highest number of total beads used in 37 necklaces = 2,849 beads

Hence, the total number of beads used in making 37 necklaces is between 2,664 beads and 2,849 beads.

In a survey of 400 randomly selected people, it was determined that 22 play soccer. What is the probability that a randomly sel

insens350 [35]

Answer:

5.5% probability that a randomly selected person plays soccer

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

People surveyed who play soccer, so $D = 22$

Total outcomes:

Total people surveyed, so $P = 400$

What is the probability that a randomly selected person plays soccer?

$P = \frac{D}{T} = \frac{22}{400} = 0.055$

5.5% probability that a randomly selected person plays soccer

A carpenter purchased 50 ft of redwood and 80 ft of pine for a total cost of $285. A second purchase, at the same prices, includ

Marizza181 [45]

Hey there!!

Let us take the price of the redwood as ' x ' and pine as ' y '

Then , we take it into an equation. We get,

50x + 80y = 285 -------------- ( 1 )

80x + 50y = 339 -------------- ( 2 )

Now, multiply the first equation with 8 and the second equation with 5

400x + 640y = 2280

400x + 250y = 1695

Now subtract the second equation from the first

390y = 585

y = 585 / 390

y = $1.5

Now substitute this into any equation

50x + ( 80 ) ( 1.5 ) = 285

50x + 120 = 285

50x = 165

x = 165 / 50

x = $3.3

Redwood = $3.3

Pine = $1.5

Hope helps!
