Answer:

1,206 ft

Step-by-step explanation:

6/4 = 1.5   ( proportion 1.5)

804(1.5) = 1,206

94%

47/50 × 100 = 47 ×2 = 94 %

Answer:

94%

Step-by-step explanation:

Basically you need to divide the numerator (47) by the denominator(50). Then after you do that you will find yourself with a decimal of 0.94. lastly multiply your decimal by 100 to get your final answer, which is 94%.

Answer:

The answer is 32.5

Step-by-step explanation:

First start with (6x3) + ( 8 x 5 ) + ( 9 x 1 ) + ( 10 x 7 ) + ( 12 x 4 ) + ( 13 x 2 ) + ( 14 x 1 ). This equals 225 pounds for all of the pumpkins. The baker buys all of them so multiply 225 by 0.30 since each pound costs 0.30. 225 x 0.30 = 67.5 and the baker pays a 100 dollars so 100 - 67.5 = 32.5. The answer is 32.5.

P.S: I has this same question and 32.5 was correct. PLZ give me Brainliest. Thank you!

Answer:

3 students

Step-by-step explanation:

Two ways you can do this:

1. If you have a graphic calculator you can find the normal distribution function and enter the following values to get the probability of a student finished in less than 5 minutes:

Lower: 0

Upper: 5

Standard Deviation: 1

Mean: 6

This gives a probability of: 0.1587 (4.d.p)

2. You can use the formula and find the probability using the Z-table.

[tex]Z = \frac{x - \mu}{\sigma}[/tex]

Substitute known values:

[tex]Z = \frac{5 - 6}{1}\\Z = -1/1 = -1\\[/tex]

It is one standard deviation to the left of the mean,.

Look up on Z-score table and we get: 0.1587 (4.d.p)

Now we need to find expected number. We do this by multiplying the probability by the amount of people:

0.1587 x x19 = 3.0153 rounded to 3 students.

Hope this helped!

Answer:

20oz

Step-by-step explanation:

60%=12oz

this can be simplified into 1%

in order to find 1% divide by 60

60%/60=1%

in order to find out how much 1% is, divide 12oz by the number used to divide the percent

12/60=0.2

so 0.2=1% and we want to know 100% so multiply by 100

0.2x100=20

1%x100=100%

so 20oz=100% of the bottle

Answer:

x = 2

y = 3

Step-by-step explanation:

2y = 6

y = 3

32x=0

x= 0/32

Answer:

the answer would be 3 1/2

Step-by-step explanation:

if you simplify -7/2 it would be -3 1/2, and the opposite of -3 1/2 is 3 1/2.  And from 0-3 there are 6 spaces, so every two spaces counts as 1. Therefore the point would go one spot after positive 3.

Step-by-step explanation:

Hometown Donuts recently sold 19 donuts, of which 6 were cream-filled donuts. What is the experimental probability that the next donut sold will be a cream-filled donut?

Write your answer as a fraction or whole number.

-------------------------------------------------------------------------------------------------------------

Remember That The experimental probability is the number of times an event occurs out of the total number of trials.

-------------------------------------------------------------------------------------------------------------

So. Write the experimental probability as a fraction in simplest form: P(Cream-Filled Donuts) = Cream-Filled Donuts over / divided by the total (Cream-Filled Donuts/Total)

-------------------------------------------------------------------------------------------------------------

= 6/19

-------------------------------------------------------------------------------------------------------------So, The Answer Would Be 6/19

This is the right answer, I had the same question ^^

The simplified answer is 27m^2

The simplification of the given expression is equal to (336a² + 27[tex]a^{(2-2m)[/tex])/256.

To simplify the expression, let's start by expanding each term and then combining like terms:

Expand the first term (4[tex]a^m[/tex] + 3)³

(4[tex]a^m[/tex] + 3)³ = (4[tex]a^m[/tex]  + 3)(4[tex]a^m[/tex] + 3)(4[tex]a^m[/tex]  + 3)

Using the binomial expansion formula for (a + b)³

(a + b)³ = a³ + 3a²b + 3ab² + b³

So, for (4[tex]a^m[/tex]  + 3)³

(4[tex]a^m[/tex]  + 3)³ = 4³ × ([tex]a^m[/tex] )³ + 3 ×4² [tex]a^m[/tex]  ([tex]a^m[/tex] )²× 3 + 3 × 4× ([tex]a^m[/tex] ) × 3² + 3³

= 64[tex]a^{(3m)[/tex] + 144[tex]a^{(2m)[/tex] + 108[tex]a^m[/tex] + 27

Expand the second term (1/16[tex]a^{(1-m)[/tex])²

(1/16[tex]a^{(1-m)[/tex])² = (1/16[tex]a^{(1-m)[/tex]) (1/16[tex]a^{(1-m)[/tex])

Simplify the square of a fraction by squaring the numerator and denominator separately:

(1/16[tex]a^{(1-m)[/tex])² = (1²)/(16²) × ([tex]a^{(1-m)[/tex])²

= 1/(256) × [tex]a^{(2(1-m))[/tex]

=[tex]a^{(2-2m)[/tex]/256

Now, let's multiply both simplified terms:

(4[tex]a^m[/tex] + 3)³ ×(1/16[tex]a^{(1-m)[/tex])²

= (64[tex]a^{(3m)[/tex] + 144[tex]a^{(2m)[/tex]+ 108[tex]a^m[/tex]+ 27)  ([tex]a^{(2-2m)[/tex]/256)

Now, combine the terms with similar exponents:

= (64[tex]a^{(3m)[/tex]  [tex]a^{(2-2m)[/tex] + 144[tex]a^{(2m)[/tex] [tex]a^{(2-2m)[/tex]+ 108[tex]a^m[/tex]  [tex]a^{(2-2m)[/tex] + 27 × [tex]a^{(2-2m)[/tex])/256

Using the property [tex]a^m \times a^n = a^{(m+n):[/tex]

= (64[tex]a^{(3m + 2 - 2m)[/tex]+ 144[tex]a^{(2m + 2 - 2m)[/tex] + 108[tex]a^{(m + 2 - 2m)[/tex]+ 27[tex]a^{(2-2m)[/tex])/256

Simplify the exponents,

= (64a² + 144a² + 108a² + 27[tex]a^{(2-2m)[/tex])/256

Now, combine the like terms:

= (336a² + 27[tex]a^{(2-2m)[/tex])/256

Therefore,  the simplified expression is equal to (336a² + 27[tex]a^{(2-2m)[/tex])/256.
