2.1 gaallons of honey

Step-by-step explanation:

If you have to istrubute things then its obvous you need to divide something.  To get 19 equally into 9 containers you divide 19 by 9 an get 2.1

I hope this helped

Each jar will have approximately [tex]\( \boxd{2.111 \text{ gallons}} \)[/tex] of honey.

Step 1

To find out how much honey will be in each jar when Jill distributes all of the honey equally among 9 jars, we need to divide the total amount of honey by the number of jars.

Given:

Total amount of honey = 19 gallons

Number of jars = 9

So, to find out how much honey each jar will have, we divide the total amount of honey by the number of jars:

[tex]\[ \text{Amount of honey per jar} = \frac{\text{Total amount of honey}}{\text{Number of jars}} \]\[ \text{Amount of honey per jar} = \frac{19 \text{ gallons}}{9} \]\[ \text{Amount of honey per jar} = \frac{19}{9} \text{ gallons} \][/tex]

Step 2

Now, let's perform the division:

[tex]\[ \text{Amount of honey per jar} = 2.111111 \text{ gallons} \][/tex]

So, each jar will have approximately [tex]\( \boxd{2.111 \text{ gallons}} \)[/tex] of honey.

There are 15 girls and 18 boys. Therefore, the ratio of girls to boys in the cafeteria is 15 : 18 (or 15/18). However, both sides can be divided by 3, which simplifies the ratio to 5 : 6 (or 5/6).

Hope this helps!! :)

Answer: The ratio would be 5 girls to every 6 boys.

Step-by-step explanation:

Find a common number both can be divided be which would be 3, so 15 by 3 is 5, and 18 by 3 is 6. So, there is 5 girls for every 6 boys which is the ratio.

320 cubic inches

128 cubic inches

448 cubic inches

Step-by-step explanation:

Step 1:

Given,

Dimensions of the first rectangular prism = l * b * h = 16*5*4

[length is 16 as the total length is 20 and the width of the 2nd prism till the dotted line is 4]

Dimensions of the second rectangular prism = l * b * h = 4*4*8

We need to determine  volume of the 2 prisms and the whole figure. The volume of  rectangular prism can be obtained by multiplying the length breadth and the height.

Step 2:

Volume of the first prism = l * b * h = 16*5*4 = 320 cubic inches

Volume of the first prism = l * b * h = 4*4*8 = 128 cubic inches

The volume of the whole figure is the sum of the 2 rectangular prisms = 320 + 128 = 448 cubic inches

I got these questions correct

At x = –6, y = 11

At x = 3, y = 5

At x = 15, y = –3

At x = –12, y = 15

Solution:

The function is [tex]y=-\frac{2}{3} x+7[/tex].

The domain of the function is {–12, –6, 3, 15}.

Substitute x = –6 in the function to find y.

[tex]$y=-\frac{2}{3} (-6)+7[/tex]

y = 4 + 7

y = 11

Substitute y = 5 in the function to find x.

[tex]$5=-\frac{2}{3} x+7[/tex]

Subtract 7 from both sides, we get

[tex]$-2=-\frac{2}{3} x[/tex]

Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get

x = 3

Substitute x = 15 in the function to find y.

[tex]$y=-\frac{2}{3} (15)+7[/tex]

y = –10 + 7

y = –3

Substitute y = 15 in the function to find x.

[tex]$15=-\frac{2}{3} x+7[/tex]

Subtract 7 from both sides, we get

[tex]$8=-\frac{2}{3} x[/tex]

Multiply by [tex]-\frac{3}{2}[/tex] on both sides, we get

x = –12

At x = –6, y = 11

At x = 3, y = 5

At x = 15, y = –3

At x = –12, y = 15

Supplement of an angle measuring 50 degrees is 130 degrees

Step-by-step explanation:

Step 1 :

Given,

Measure of the angle = 50 °

We need to calculate the supplement of this angle

Step 2 :

2 angles are supplement to each other if the sum of their measures is 180°.

Hence the supplement of one angle can be computed by subtracting the value of that angle from 180°

Hence the supplementary angle to 50 ° is 180° - 50 ° = 130 °

Step 3:

Answer:

Supplement of an angle measuring 50 degrees is 130 degrees

Answer:

c = 57.5

Step-by-step explanation:

Since its 90 degree.

it would be 90 - 32.5 = c

Answer:

57.5

Step-by-step explanation:

It’s a 90 degree angle, which means the angles added together make 90. So if you want to get the missing angle, subtract the 32.5 angle to see what remains. That is your missing angle

The reciprocal property is:

[tex]\frac{x - 3}{12} = \frac{x + 3}{20}[/tex]

Solution:

Given that,

[tex]\frac{12}{x - 3} = \frac{20}{x + 3}[/tex]

The reciprocal property is given as:

The reciprocal of a fraction is the numerator and denominator switched

[tex]\frac{a}{b} = \frac{c}{d}\\\\Then\\\\\frac{b}{a} = \frac{d}{c}[/tex]

Therefore,

[tex]\frac{12}{x - 3} = \frac{20}{x + 3}[/tex]

By reciprocal property,

Switch the numerator and denominator of right side fraction as well as left side fraction

The we get,

[tex]\frac{x - 3}{12} = \frac{x + 3}{20}[/tex]

Thus option C is correct

Answer: Your answer for 13 people should be somewhere in the 20% range. Letting n=13 and we have about a 80.56% probability that no two out of the 13 share a birthday. As stated, the complement of this is the probability that at least two of the 13 share a birthday.

Step-by-step explanation:

The probability that 13 people have different birthdays is calculated by multiplying the individual probabilities for each person, considering each additional person has one less available day to have a unique birthday, resulting in an overall probability of approximately 83.3%.

The question asks what the probability is that 13 people have different birthdays, assuming we can neglect the impact of leap years. To solve this, we consider that there are 365 days in a year for a birthday to occur. The first person can have their birthday on any day, so the probability is 365/365. For the second person to have a different birthday, there are 364 possible days left, so the probability is 364/365. This pattern continues down for all 13 people.

To find the overall probability, we multiply these probabilities together:

Overall probability = (365/365) * (364/365) * (363/365) * ... * (353/365) = 0.833, or 83.3% when rounded to one decimal place.

This calculation is a practical application of probability theory, demonstrating how the likelihood of events changes as conditions evolve, such as when considering the probability of shared birthdays among a group of people.

Answer:

Every 1 Block he is planting 5 tree's.

Step-by-step explanation:

There are multiple ways you can do it but the easiest I prefer is just to divided The Tree's by the Blocks.

Ex: 6 Blocks is 30 trees, Divide 30 by 6 and you get 5 for every block.

Emanuel is planting trees at a rate of 5 trees per block. This is determined by dividing the total number of trees by the total number of blocks planted.

Emanuel is planting trees at a consistent rate. To find this rate, we can set up a simple ratio.

He planted 15 trees in 3 blocks, which simplifies to 5 trees per block. This can be confirmed by looking at the second part of the problem. After 5 blocks, he had planted 25 trees. If we divide the total number of trees by the total number of blocks (25 trees / 5 blocks), we also get 5 trees per block.

Therefore, the rate at which Emanuel is planting trees is 5 trees per block.

Answer: About 4 movies

Step-by-step explanation:

1 2/3 times 4/1 = 28/5

28/5 converted to a mixed number is 5 3/5

so therefore it would be ABOUT 4 movies

To find the number of movies that can be downloaded, divide the total downloading time by the time it takes to download one movie. In this case, 15 movies can be downloaded.

To find the number of movies that can be downloaded, we need to divide the total downloading time by the time it takes to download one movie. First, convert the mixed number 5 1/4 to an improper fraction, which is 21/4. Then, multiply 21/4 by the reciprocal of 1 2/5, which is 5/7. This gives us a total of 15 movies that can be downloaded.

[tex]f(x) = 2x^2 - 1[/tex]

We have to find the vertex and axis of symmetry

The general equation is given as:

[tex]f(x) = ax^2 + bx + c[/tex]

Comparing with given equation,

a = 2

b = 0

c = -1

The axis of symmetry is given as:

[tex]x = \frac{-b}{2a}[/tex]

[tex]x = \frac{0}{2(2)}\\\\x = 0[/tex]

Thus axis of symmetry is 0

The x coordinate of the vertex is the same

x coordinate of the vertex = 0

h = 0

The y coordinate of the vertex is:

k = f(h)

k = f(0)

[tex]f(0) = 2(0) - 1\\\\f(0) = 0 - 1\\\\f(0) = -1[/tex]

Thus, y coordinate of the vertex is -1

Therefore, vertex is (0, -1)
