Answer:

Probability to pick yellow or orange sweet = 3 / 8

Step-by-step explanation:

Given:

Number of yellow sweet = 5

Number of red sweet = 4

Number of green sweet = 8

Number of orange sweet = 4

Number of white sweet = 3

Find:

Probability to pick yellow or orange sweet

Computation:

Total number of sweets = 24 sweets

Probability to pick yellow = 5 / 24

Probability to pick orange = 4 / 24

Probability to pick yellow or orange sweet = 5/24 + 4 / 24

Probability to pick yellow or orange sweet = 9 / 24

Probability to pick yellow or orange sweet = 3 / 8

Use a system of equations to solve this problem. Hunter needs 10 oz of a snack mix that is made up of seeds and dried fruit. The
motikmotik

The hunter should purchase 3 ounces of seeds and 7 ounces of dried fruit to satisfy the scenario.

<u><em>Explanation</em></u>

x= the amount of seeds and y= the amount of dried fruit.

As the hunter needs total 10 ounces of a snack mix , so the first equation will be..

x+y= 10 .....................................(1)

Now the seeds cost $1.50 per ounce and the dried fruit costs $2.50 per ounce. And the mixture costs $2.20 per ounce, so the second equation will be:

1.50x+2.50y= 2.20*10\\ \\ 1.50x+2.50y= 22.........................................(2)

According to the substitution method, we will isolate y from the first equation as y= 10- x

Now we will substitute this y= 10- x into the second equation in place of y

1.50x+2.50(10-x)= 22\\ \\ 1.50x+25-2.50x =22 \\ \\ -1.00x = 22-25 \\ \\ -1.00x= -3\\ \\ x= 3

Plugging this x=3 into the equation y= 10- x , we will get...

y= 10-3 =7

So, the hunter should purchase 3 ounces of seeds and 7 ounces of dried fruit to satisfy the scenario.

Esther needs a bin for her hair bows. A yellow bin has a length of 11.4 inches, a width of 4.2 inches, and a height of LaTeX: \f
fenix001 [56]

Answer:

Yellow Bin

Step-by-step explanation:

<u>Yellow Bin</u>

Length = 11.4 inches,

Width = 4.2 inches,

Height =  \frac{8}{3}

Volume of the yellow bin=LWH=11.4 X 4.2 X \frac{8}{3}=127.68 \:cubic \:inches

<u>Red Bin</u>

Length = 9 inches,

Width = 5.45 inches,

Height =  \frac{11}{5}

Volume of the red bin=LWH=9X 5.45 X \frac{11}{5}=107.91 \:cubic \:inches

The yellow bin has a greater volume since 127.68 is greater than 107.91.
