Answer:

7x+1 ≤12

Step-by-step explanation:

The common letter used to represent a variable is x. Thus, a 7 is added to it to signify that it is being multiplied. Then, increased by one means +1. At most is a fancy word for less than or equal to ( ≤).

Answer:

8.5

Step-by-step explanation:

The median of the data in the dot plot for the score for each student in Mrs. Baker's class is 8.5.

The median of the data is the middle value of the data set when it arrange in ascending or descending order.

The dot plot for the Mrs. Baker's class is is shown in the figure attached below.

In the increasing order, the data of the image is arranged below.

0,1,5,7,8,8,9,9,9,10,10,10

There are total 12 values in the is data which is even. The middle term is 8 and 9 in the arranged data. For the even values, the median is the average of both the values.

[tex]m=\dfrac{8+9}{2}\\m=8.5[/tex]

Thus, the median of the data in the dot plot for the score for each student in Mrs. Baker's class is 8.5.

Answer:

Substraction

Step-by-step explanation:

Given that  

The amount paid in the year 2018 is $3,200

And, in the year 2019 the amount paid is $3,516'

We need to find the differnece between two years so how we can find

Basically we need to subtract the amount i.e.

= $3,516 - $3,200

= $316

hence, the difference is of $316 from 2018 to 2019

Answer:

La respuesta es falso.  

Step-by-step explanation:

La respuesta es falso.  

Cuando se suman fraccciones con igual denominador, se suman los numeradores (numerador con numerador) y se deja el mismo denominador (el cual es común en ambos). Por ejemplo, la suma de 1/5 + 3/5 da como resultado:    

[tex] \frac{1}{5} + \frac{3}{5} = \frac{1 + 3}{5} = \frac{4}{5} [/tex]

En el caso de fracciones con diferentes denominadores, tampoco se suma numerador con numerador y denominador con denominador. En ese caso se debe encontrar el mínimo común múltiplo.

Por lo tanto, la respuesta es falso.

Step-by-step explanation:

==========================================================

Explanation:

For each row, multiply the values straight across.

The list of products we got were: 1, 6, 0, 8, 5, 18

Add up those products to get: 1+6+0+8+5+18 = 38

The value 38 represents the total value if we were to add up all of the results of each die roll (it shows up again in the next section). We divide this over the total frequency, which is the sum of everything in the second column. That total frequency being 1+3+0+2+1+3 = 10.

So the mean is 38/10 = 3.8

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

A longer way to do this is to expand each value based on the frequency shown. The value '1' shows up one time, so we just write "1" once. The value "2" shows up three times, so we write "2" three times. So far the list is {1,2,2,2}

The value "3" doesn't show up at all, so we skip to "4" which shows up twice. The updated data set so far is {1,2,2,2,4,4}

Then it updates again to {1,2,2,2,4,4,5} when we account for the single "5"

Finally, the fully up to date list of values is {1,2,2,2,4,4,5,6,6,6}

Computing the mean of this set has us add up the values to get 1+2+2+2+4+4+5+6+6+6 = 38. We have that "38" show up again, which is not a coincidence. We divide over 10 because there are ten values in the fully up to date list shown above. So this is a different method to get the mean of 3.8

If you prefer this second method, then you should use it; however, I recommend the first method as it's faster and more efficient. It might be handy to try both methods just for practice.

Answer:

There are calculators for these things, you know! You can look one up!

Step-by-step explanation:

In order to calculate the height (distance BC in the diagram) you need to know the distance from point D (the closer of the two measurement points to the kite) to the point directly under the kite, B. Once you know this distance then multiplying this by the tangent of angle b will give you the height.

Answer:

  a) 5 cm

  b) 8 cm

  c) 9 m

Step-by-step explanation:

It can be worthwhile to work the last attachment (a) first, since these are all variations of the same triangle.

The Pythagorean theorem tells you the sum of the squares of the legs is the square of the hypotenuse.

Problem 6a:

  3² +4² = x² . . . . fill in the given numbers; all measures in cm

  9 + 16 = x² . . . . simplify exponents

  25 = x² . . . . . . . simplify sum

  x = √25 = 5 . . . take the square root.

  x = 5 cm . . . . . . apply units

__

Note that this triangle is a 3-4-5 right triangle. That is a set of side lengths (ratios) that is useful to remember. In this problem set, you see it again immediately.

__

Problem 6b:

Shortest-to-longest, the side ratios of the given triangle are ...

  6 : x : 10

For some x', this is ...

  3 : x' : 5 . . . . . . . . . . . . . matches a 3-4-5 triangle with x' = 4

The scale factor is 6/3 = 10/5 = 2, so we have ...

  x = 2·x' = 2·4 = 8

  x = 8 cm . . . . . with units

__

Problem 6c:

The side ratios are ...

  x : 12 : 15  which reduces to  x' : 4 : 5

This matches a 3-4-5 triangle with x' = 3, and a scale factor of 12/4 = 15/5 = 3.

Then ...

  x = 3·x' = 3·3 = 9

  x = 9 m . . . . . with units

The rate of tax is 12%

Suppose x is the amount of charge before tax inclusion

We can write

[tex]\Rightarrow x+12\%x=319.19\\\Rightarrow x(1+0.12)=319.19\\\\\Rightarrow x=\dfrac{319.19}{1.12}\\\\\Rightarrow x=\$284.99\approx \$285[/tex]

The amount before tax inclusion is $285

Liters

Step-by-step explanation:

a Mili(thousandth)liter is a small unit of volume. Liters( a thousand milliliters) is the base unit of volume and larger, so it's B.  

The requried to wash her car, Amy used 25 liters of water. Option B is correct.

Unit of measurement is defined as every entity having its measures in dimensions, weight, and time. Such as for length we have a meter, for liquid we have liters, and so on.

Here,
The question doesn't specify what unit of measurement the 25 refers to, so it's unclear whether the answer should be in milliliters or liters. However, assuming that the unit of measurement is liters, the answer would be:

Amy used 25 liters of water to wash her car.

If the unit of measurement is milliliters, the answer would be:

Amy used 25,000 milliliters of water to wash her car.

Note that 1 liter is equal to 1000 milliliters, so 25 liters is equal to 25,000 milliliters.

Thus, the requried To wash her car, Amy used 25 liters of water. Option B is correct.

Answer:

hmm,,,,,,

Step-by-step explanation:

Given:

The polynomial [tex]x^3-1[/tex] is divided by (x+2).

To find:

The remainder.

Solution:

Remainder theorem: If a polynomial p(x) is divided by (x-c), then the remainder is p(c).

Consider the polynomial:

[tex]p(x)=x^3-1[/tex]

It is divided by (x+2). So, by the remainder theorem the remainder is p(-2).

Substituting x=-2 in the above polynomial, we get

[tex]p(-2)=(-2)^3-1[/tex]

[tex]p(-2)=-8-1[/tex]

[tex]p(-2)=-9[/tex]

Therefore, the remainder is -9.

The remainder when x³ - 1 is divided  by (x + 2) is -9

Polynomial is an expression consisting of only the operations of addition, subtraction, multiplication of variables.

The remainder theorem states that when a polynomial f(x), is divided by a linear polynomial x - a, the remainder of that division will be equivalent to f(a).

Given the polynomial f(x) = x³ - 1.

The linear equation is x + 2, hence; x = -2

f(-2) = (-2)³ - 1 = -8 - 1 = -9

The remainder when x³ - 1 is divided  by (x + 2) is -9

Answer:

x = 69

Step-by-step explanation:

angles in a triangle add up to equal 180

which means that, x + x + x - 27 = 180

x + x + x = 3x

3x - 27 = 180

* add 27 to both sides *

-27 + 27 cancels out

180 + 27 = 207

207 = 3x

* divide both sides by 3 *

3x / 3 = x

207 / 3 = 69

we're left with x = 69

Answer: 2.28 times

Step-by-step explanation:

When finding out the number of times more that the animal shelter used chew toys than Jenna's dogs, you need to divide the number used by the animal shelter by Jenna:

= Number used by animal shelter / Number used by Jenna's dogs

= 2,277 / 999

= 2.28 times

Notice that if you multiply Jenna's dogs 999 toys by 2.28 you will get approximately 2,277.
