Answer:

E = 8

Step-by-step explanation:

y - x = 4

y - (3y) = 4

y - 3y = 4

2y = 4

y = 4/2

y = 2

x = 3y

x = 3×2

x = 6

x + y = 2+6

x+y = 8

The word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}

A set is a collection of clearly - defined unique items. The term "well-defined" applies to a property that makes it simple to establish whether an entity actually belongs to a set. The term 'unique' denotes that all the objects in a set must be different.

We have given letter:

"salt"

Here, no letter is repeated.

So we can write it as roaster form:

Let's denote the set as S

S = {s, a, l, t}

Number of element in the set = 4

We can make new set from it if the set has only vowels

S(v) = {a}

If set has only consonants:

S(c) = {a, l, t}

Thus, the word can be represented as a set and in the roaster form the set of letters is {s, a, l, t}

So the diamiter is really easy to find. It is just twice the radise. So if the radis is 6 then you do 6*2=12

Answer:

C(50;-20)

Step-by-step explanation:

The question is asking for the midpoint of the line.

The triangle is formed by placing a line directly from the y-axis to the x-axis.

The midpoint theorem is[ (x1+x2)/2 ; (y1+y2)/2 ].

your coordinates at A is (0;-40), because the x value is 0 on the line as shown in the diagram above point A.

Your coordinates for B are (100;0)

C[(x1+x2)/2 ; (y1+y2)/2 ]

C [(0+100)/2 ; (-40+0)/2 ]

C[ 100/2 ; -40/2]

Step-by-step explanation:

The problem is put in different fractions to make it more confusing.

1 1/15 miles+ 1 3/5 miles+ 1 2/3 miles

We can find the common denominator of all of the fractions.

[tex]1 \frac{1}{15} + 1 \frac{9}{15} + 1 \frac{10}{15} \\= 3+\frac{20}{15} =4 \frac{5}{15}\\\\=[/tex]4  1/3

[tex]monday = 1 \frac{1}{15} [/tex]

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

[tex]wednesday = 1 \frac{2}{3} [/tex]

the total number of miles Kenya ran in 3 days.

[tex] \frac{16}{15} + \frac{8}{5} + \frac{5}{3} [/tex]

[tex] = \frac{16}{15} + \frac{8 \times 3}{5 \times 3} + \frac{5 \times 5}{3 \times 5} [/tex]

[tex] = \frac{16 + 24 + 25}{15} [/tex]

[tex] = \frac{65}{15} = \frac{13}{3} [/tex]

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

therefore, the correct answer is option D.

Hi!

One yard is equal to 3 feet.

Therefore, we can simply divide the number of feet by 3 to get the number of yards.

First, let's convert 9 feet into yards.

9/3 = 3 yards

So, we know that 3 yards of cotton cloth cost $15.84

To get the price per yard, we want to divide the number by 3, as there are 3 yards total.

We will get the price per yard by doing that.

15.84 / 3 = 5.28

Therefore, the price per yard is $5.28.

For a similar problem, see:

https://brainly.com/question/22543439

Answer: $5.28 per yard

Step-by-step explanation:

   There are 3 feet in one yard. We can divide 9 by 3 to see how many yards the price given is for.

       9 / 3 = 3

       This piece of cotton cloth is 3 yards. To find the price of one yard, we will divide the cost given by 3.

$15.84 / 3 = $5.28 per yard

         The price per yard is $5.28.

Answer:

79.94

Step-by-step explanation:

First, let us find the circumference of the wheel (circle).

For that, let us use the below formula.

C = π × d

Given that,

d ⇒ diameter ⇒ 150 cm ⇒ 1.5 m

Let us find now.

C = π d

C = 3.142 × 1.5

C = 4.713

And now to find the number of times that the wheel rotates, you have to divide the total distance that wheel traveled by it's circumference.

Let us find now.

No. of times that wheel rotates = 376.8m ÷ 4.713m

No. of times that wheel rotates = 79.94

Approximately, the wheel will rotates 80 times.

Answer:

the last answer is correct, lim as it aproaches 33- is -6, and as it aproaches 33+ is -15

Step-by-step explanation:

The limit as the function approaches 33+ means the limit as the function approaches 33 from the right side, and the table shows it approaches 15 from x is above 33.

When x is slightly below 33, it aproaches -6.

The values of lim g (x) when x → - 33 and lim g(x) when x → 33 are,

⇒ - 6 and 15

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

We have to given that;

Table shown the relation between x and g (x).

Now, By table we get;

At x = 32.999;

g (x) = - 6.01

At x = 33.001;

g (x) = - 15.01

Thus, The values of lim g (x) when x → - 33 and lim g(x) when x → 33 are,

⇒ - 6 and 15
