Answer:

J

Step-by-step explanation:

Answer:

Line segments J'K' and M'N' do not intersect and are the same distance apart as JK and MN.

Step-by-step explanation:

If the line segments are translated 2 units to the left, then JK will start at (1, -1) and go to (5, -1), and MN will start at (1, -2) and to to (5, -2).  So the line segments remain parallel and the same distance apart.

Answer:

Week                   Mass  (gram)

(start)                    80

   1                         88  

   2                        96.8

   3                         106.48

   4                          117.128

Step-by-step explanation:

From the question we are told that

   The  mass of the kitten at the start week  is  m  =  80 g

   The rate at which the kitten grows is  r  =  0.10

Generally the mass of the kitten at the first  week is mathematically represented as  

    [tex]m_1 = ( r *  m)  + m[/tex]

=>[tex]m_1 = ( 0.10 *  80 )  + 80 [/tex]      

=>[tex]m_1 = 88 \ g  [/tex]      

Generally the mass of the kitten at the second week is mathematically represented as  

     [tex]m_2 = ( r *  m_1)  + m_1[/tex]

=>[tex]m_2 = ( 0.10 *  88 )  + 88 [/tex]      

=>[tex]m_2 = 96.8 \ g  [/tex]      

Generally the mass of the kitten at the third  week is mathematically represented as  

     [tex]m_3 = ( r *  m_2)  + m_2[/tex]

=>[tex]m_3 = ( 0.10 *  96.8)  + 96.8 [/tex]      

=>[tex]m_3 = 106.48  \ g  [/tex]      

Generally the mass of the kitten at the fourth  week is mathematically represented as  

     [tex]m_4 = ( r *  m_3)  + m_2[/tex]

=>[tex]m_4 = ( 0.10 *  106.48)  + 106.48 [/tex]      

=>[tex]m_4 = 117.128  \ g  [/tex]              

Week                   Mass  (gram)

(start)                    80

   1                        88  

    2                      96.8

answer:35 grams

explication: because if he need 350 grams of sugar to make 100 cookies , we have to divide 350 by 100 so it gives 35

The number of grams of sugar would he need to bake 10 cookies will be 35 grams.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

To bake 100 of his favorite cookies, Mr.Wallis needs 350 grams of sugar.

Let x be the amount of sugar for 10 cookies.

The number of grams of sugar would he need to bake 10 cookies will be

x / 10 = 350 / 100

x / 10 = 3.5

x = 35 grams

The number of grams of sugar would he need to bake 10 cookies will be 35 grams.

f(-9)= -189

Step-by-step explanation:

f(-9)= -3(-9)^2-6(-9)

f(-9)= -3(-9)^2 +54

f(-9)= -3(81) +54

f(-9)= -243 + 54

f(-9)= -189

[tex]f(-9)[/tex]  is [tex]-189[/tex]

What is function?

In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function. Functions were originally the idealization of how a varying quantity depends on another quantity.

According to question, we have the function [tex]f(x)=-3x^2-6x[/tex]

We have to find [tex]f(-9)[/tex]

So,  [tex]f(-9)=-3[/tex]×[tex](-9)^{2}[/tex][tex]-6(-9)[/tex]

                [tex]=-243+54[/tex]

                [tex]=-189[/tex]

Hence, we can conclude that   [tex]f(-9)[/tex] is [tex]-189[/tex]

Answer:

PART ONE- 8/50 PART 2-38/50

Step-by-step explanation:

First of all, we know that there are 50 states. Lets see how many states begins with M first.

Maine‎ (27 C, 5 P)

Maryland‎ (28 C, 5 P)

Massachusetts‎ (29 C, 4 P)

Michigan‎ (28 C, 4 P)

Minnesota‎ (28 C, 2 P)

Mississippi‎ (27 C, 6 P)

Missouri‎ (25 C, 3 P)

Montana‎ (27 C, 6 P)

There are 8 states which means that the probabilty is 8/50 which simplifies to 4/25

We know that 12 states begins with a vowel. 50-12 is 38/50

The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.

Given that, Selecting a State, Choose one of the 50 states at random.

We know that, P(A) = n(A)/n(S)

where, P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.

a) There are 8 states which begins with M, that means the probability = 8/50 = 4/25 = 0.16

b) We know that 12 states begins with a vowel,

Therefore, the probability that it doesn't begin with a vowel = 1 - 12/50 = 38/50 = 0.76

Hence, The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76

Answer:

Step-by-step explanation:

In the first mixture the concentration syrup is higher

Concentration syrup is higher in mixture B.

Two or more ratios made to be equal to each other is termed as proportion.

We have to use the proportional concept here by finding the concentration of syrup in 1 l of water.

Mixture A:

Concentration of syrup in 3 l of water = 2 l

Concentration of syrup in 1 l of water = 2/3 l = 0.67 l

Mixture B :

Concentration of syrup in 2.5 l of water = 1.8 l

Concentration of syrup in 1 l of water = 1.8 / 2.5 = 0.72 l

Concentration of syrup in mixture A in 1 liter of water is less than the concentration of syrup in mixture B in 1 liter of water.

Hence the concentration of syrup in mixture B is higher because concentration of syrup in mixture B in 1 liter of water is higher than the concentration of syrup in mixture A in 1 liter of water.
