Answer:

8mm

Step-by-step explanation:

A cube with 2mm is 8mm

Answer:

Its depends on the shape of the container. If its a cube then it is 8mm

Step-by-step explanation:

to find volume, its length x width x height so

2mm x 2mm x 2mm = 8mm

In comparison to 1/3 to 3/9, both numbers are located at the same point on a number line.

It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.

It is given that:

In comparison 1/3 to where would 3/9 be located on a number line

As we know, a number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.

1/3 = 0.333

3/9 = 1/3 = 0.333

If we plot the above fractions on a number line we will see these two fractions are on the same point.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Thus, in comparison to 1/3 to 3/9, both numbers are located at the same point on a number line.

I took the quiz on K12

Answer:

-18

Step-by-step explanation:

If you're looking for the y-intercept for this equation this means that x = 0.

So substitute x as 0 in the equation and you'll get the following.

y + 3 = 5 (0 - 3)

y + 3 = -15

y = -18

Answer: Length = 24; width =4

Step-by-step explanation

Since the ratio of the length to width is 6:1

Let the length  be represented as  6x

And the width be  = x

Such that that the Perimeter of the rectangle which is  

Perimeter = 2(length + width)  becomes

56 = 2(6x + x)

56/2 = 6x+x

28 = 7x

x = 4

Width = 4

Length = 6x= 6 x 4 = 24

Answer:

all students each grade, its a better representation of the wants of the whole group being affected

Step-by-step explanation:

Answer:

C: All students in each grade

Step-by-step explanation:

It cant be all teachers in the school since at the beginning of the question it says "whether the students" not whether the teachers plus it is not a mxed variety, so this question was sort of trying to catch you off guard

The reason why is if you pick all the boys in each grade then it wouldnt really be random since your picking the gender you want to answer it has to be a mixed variety all ages all genders and so on

Yes! All students in each grade would be a mixed variety since its all ages, all genders, and all grades this answer was a little obvious since they sort of gave you the answer saying "The social studies teacher wants to know whether the students in the entire school"

All students in the social studies club wouldnt be a good answer either since (as i said before) it has to be random and your picking who you want to answer plus since there in the club with the social studie steacher they are more likely to pick what she wants to pick

So the answer would be C: All students in each grade

Answer:

Step-by-step explanation:

5 2/5 = [(5*5)]+2 / 5 = (25+2) / 5 = 27/5

(27/5)/(9/10) = 27/5 * 10/9

cross cancel 27 becomes 3 and 9 becomes 1, 5 becomes 1 and 10 becomes 2

= 3/1 * 2/1 = 6/1 = 6

Answer:

The weight of dogs x = 38pounds

Step-by-step explanation:

Step(i):-

Given that the mean weight of a group of dogs

       μ = 38 pounds

Let 'x' be the weight of dogs

Let 'x' be the random variable in normal distribution

Given that z-score is zero

Step(ii):-

we know that the z-score

                   [tex]Z = \frac{x-mean}{S.D}[/tex]

            ⇒  [tex]0 = \frac{x-38}{S.D}[/tex]

            ⇒ 0 = x-38

           ⇒  x-38 = 0

          ⇒   x =38

Final answer:-

The weight of dogs x = 38pounds

Answer:

There are many..

One would be y = 4x + 7

The trick is the slope is always the same. The only difference is the y-int. You could make one yourself, just use 4x at the beginning.

Answer:

  y = 4x

Step-by-step explanation:

A parallel line will have the same slope. The given line is written in "slope-intercept form", so the slope is readily identified from the equation.

  y = mx + b . . . . . line with slope m and y-intercept b

  y = 4x -7 . . . . . . line with slope 4 and y-intercept -7

So, the parallel line will be something of the form ...

  y = 4x + b

for any value of b. The simplest is to let b=0. If b=-7, then the lines are coincident, not parallel, so that value must be excluded. Any other value of y-intercept will give a parallel line.

  y = 4x . . . . . parallel line

Answer:

  bus: 324 ft long

  P-H: 1154 miles

Step-by-step explanation:

In each case, we can use the relation that the length of an arc (s) is found by ...

  s = rθ

where r is the radius and θ is the angle in radians.

__

1. 2°20'50" = (2 + 20/60 + 50/3600)(π/180) radians ≈ 0.0409668 radians

Then the length of the bus is ...

  (0.0409668)(1.5 mi)(5280 ft/mi) = 324 ft

__

2. The difference in latitude is ...

  41°17'5" -24°45'30" = 16°31'35" ≈ 0.288440 radians

Then the mileage between latitude lines is ...

  s = (4000 mi)(0.288440 radians) ≈ 1154 miles

__

Additional comment

Neither of these problems should be considered to be realistic. An actual bus will subtend a far smaller angle at the given distance. The distance between cities must take into account longitude as well as latitude (and the latitudes must be properly associated with the cities).

Answer:

Juan bought 139 tickets and Alex bought 204.

Step-by-step explanation:

Suppose Juan bought a total of [tex]x[/tex] tickets. Then Alex bought 65 more, which is [tex]x+65[/tex]. The sum of both totals is [tex](x)+(x+65) = 2x + 65[/tex], but we are also given that this is equal to 343. So [tex]2x+65 = 343[/tex], and as such [tex]2x = 343-65=278[/tex], so [tex]x = \frac{278}{2} = 139[/tex]. Therefore, Juan bought 139 tickets and Alex bought 65 more, which is 204.
