-6a-12+3a
3a+12
none of the above

Answer: They are both correct

Step-by-step explanation:

Jane saying 5 is a factor for every while number that has a 5 in the ones place is correct. For example, in the number 345 or 25, we can see that we have 5 in the ones place and 5 is a common factor for the numbers.

Also, Fred saying 5 is a factor for every while number that has a 0 in the ones place is correct as well. For example, the numbers 10, 20, and 200 all have 0 in their ones place and they have a factor of 5 as well.

Therefore, both of them are correct.

Answer: 3

Step-by-step explanation: [ 3.6 ] represents the greatest integer function [ x ]

If x is an integer use that integer

If x is not an integer use the next smaller integer

[ 3.6 ] is not an integer, hence

[ 3.6 ] = 3

Step-by-step explanation:

Jillian is incorrect because the shown graph is not a radical function but a logarithmic function instead. Both radical and logarithmic increase for f(x) when x increases as well.

Note that radical functions do not have any asymptotes, that includes vertical and horizontal.

The shown graph is a logarithmic function. The name already says it. The logarithmic function is part of logarithmic where the equation is

Answer:

Step-by-step explanation:

From the given right-angle triangle

The angle = ∠60°

The hypotenuse = x

Determining the value of x:

Using the trigonometric ratio

cos 60° = adjacent / hypotenuse

substituting adjacent = 1/2 and hypotenuse = x

[tex]cos\:60^{\circ }=\:\:\frac{\frac{1}{2}}{x}[/tex]

[tex]\cos \left(60^{\circ \:}\right)=\frac{1}{2x}[/tex]

[tex]\frac{1}{2}=\frac{1}{2x}[/tex]          ∵ cos (60°) = 1/2

[tex]2x=2[/tex]

Dividing both sides by 2

[tex]\frac{2x}{2}=\frac{2}{2}[/tex]

Simplify

[tex]x=1[/tex]

Thus, the value of hypotenuse x is:

x = 1

Determining the value of y:

Using the trigonometric ratio

sin 60° = opposite / hypotenuse

As we have already determined the value of hypotenuse x = 1

substituting opposite = y and hypotenuse = 1

sin 60° = y/1

y = 1 × sin 60°

[tex]y=\frac{\sqrt{3}}{2}[/tex]       ∵  [tex]\sin \left(60^{\circ \:}\right)=\frac{\sqrt{3}}{2}[/tex]

Therefore, the value of y is:

[tex]y=\frac{\sqrt{3}}{2}[/tex]      

Summary:

Answer: 24

Step-by-step explanation:

In the morning, a farmworker packed 4 pints of strawberries every 4 minutes. The amount of pints of strawberries packed in an hour would be:

= 4/4 × 60

= 60 pints of strawberries

In the afternoon, she packed 3 pints of strawberries every 5 minutes. The amount of pints of strawberries packed in an hour would be:

= 3/5 × 60

= 36 pints of strawberries

The difference between her morning and afternoon packing rates, in pints per hour would be:

= 60 - 36

= 24

If Beatriz takes a simple random sample of 350 orders from the more than 5000 total to her store and finds. The probability that more than 12 percent of the sampled orders would have been returned is 0.02.

Mean = n * p

Mean = 350 * 0.09

Mean= 31.5

Standard deviation = √ p * (1 - p)/n

Standard deviation = √ 0.09 * 0.91/350

Standard deviation = 0.01529

Using the  normal distribution table

p>0.12

P(p>0.12) =0.02

Therefore the probability that more than 12 percent of the sampled orders would have been returned is 0.02.

Answer:

A van can carry 15 students and a bus can carry 21 students

Step-by-step explanation:

System of Equations

There are separate trips to the water park for which vans and buses were rented. Let's call the variables:

x = number of students that a van can carry

y = number of students that a bus can carry

6 vans and 8 buses were filled with 246 students. This leads to the equation:

6x + 8y = 246

Dividing by 2:

4x + 3y = 123      [1]

4 vans and 8 buses were filled with 228 students. Thus, we form the equation:

4x + 8y = 228     [2]

Subtracting [2] minus [1]:

5y = 228 - 123 = 105

Dividing by 5:

y = 105/5 = 21

y = 21

From [1]:

4x + 3*21 = 123

4x + 63 = 123

Subtracting 63:

4x = 60

Dividing by 4:

x = 60/4 = 15

x = 15

A van can carry 15 students and a bus can carry 21 students

Answer:

[tex]\sqrt{45}[/tex]

Step-by-step explanation:

Ultimately, you want to find the hypotenuse from the distance of Point A to Point B.  From point A to the center of point B, it is nine units up and from there it is three units to the right of Point B.  Use the Pythagorean theorem to get your hypotenuse in which you should get 45 as your hypotenuse and when you divide it, it is [tex]\sqrt{45}[/tex].
