Given that:

Length of a rope = 224 cm

Rope is cut so that one part is 3/4 of the other.

Solution:

Let one part of a rope be x cm.

So other part of the rope is [tex]\dfrac{3}{4}x[/tex].

Total length [tex]=x+\dfrac{3}{4}x[/tex]

Now,

[tex]x+\dfrac{3}{4}x=224[/tex]

[tex]\dfrac{4x+3x}{4}=224[/tex]

Multiply both sides by 4.

[tex]7x=896[/tex]

Divide both sides by 7.

[tex]x=\dfrac{896}{7}[/tex]

[tex]x=128[/tex]

The value of one part 128 cm.

Second part [tex]=\dfrac{3}{4}x[/tex]

[tex]=\dfrac{3}{4}\times 128[/tex]

[tex]=3\times 32[/tex]

[tex]=96[/tex]

Therefore, the length of shorter rope is 96 cm and the length of longer rope is 128 cm.

Answer:

The answer is below

Step-by-step explanation:

Let the budget be represented by B. Since the grouo has only $8,000, hence, the inequality can be represented as:

B ≤ $8000

Also, $3400 was spent on transportation. If other cost is represented by C, therefore, other cost is given as:

Other cost ≤ Budget - cost of transportation

C ≤ $8000 - $3400

C ≤ 4600

From above, to stay within the budget, all other costs must be below $4600

The Lily is correct because full numbers are not fractions and can be positive, negative, or zero.

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.

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

Lilly is on point. Integers are full numbers that are not fractions and can be positive, negative, or zero, so she is right.

Answer:

the answer to your question is -8.5

Answer:

-3.4 × 2.5 = -8.5

Step-by-step explanation:

Since these are short decimals, you can probably convert these into fractions if you'd like.

So -3.4 = -17/5

And 2.5 = 5/2.

So just multiply this like you would multiply two fractions, just multiply across the numerator, and denominator, and then just simplify; numerator × numerator / denominator × denominator.

So

The trick when multiplying by 5 is to divide the number in half, and multiply by 10.

-17/5 × 5/2 = -17 × 5 / 5 × 2 = -17/2 × 10 / 10 = -8.5 × 10/10 = -8.5 × 1 = -8.5

(The tens just cancel and make 1 so you are just left with this answer)

You can also try splitting the decimals up into factors:

-3.4 × 2.5 = (-3 - 0.4)(2 + 0.5) = -6 + -0.8 + -1.5 + 0.2 = -6 + -1 + -1.5 = -7 + -1.5 = -8.5.

Answer:

≈ 3927 litres

Step-by-step explanation:

The volume (V) of a cylinder is calculated as

V = Ah ( A is the area of the base and h the height )

Note that h of oil = 250 ÷ 2 = 125 cm ( since half full )

V = πr²h

   = π × 100² × 125 = 1250000π cm³ ( divide by 1000 )

   = [tex]\frac{1250000\pi }{1000}[/tex] = 1250π litres ≈ 3927 litres ( to the nearest litre )

Answer:

3927

Step-by-step explanation:

first u have to find volume of cylinder its volume is

V=

[tex]\pi \times radius ^{2} \times height[/tex]

so it become 7853981cm^3 then convert it into Liters as you know 1liter=1000cm^3

so divide your volume with 1000 and the answers

is 7853 so as u know that it is half filled than divied ur 7853 by 2 then final ans is 3927

Answer:

B. Exponential Function; base = 2; initial value = - 3.8

Step-by-step explanation:

hey there,

< The formula for exponential functions is [tex]A_{t} = A_{o} e^{kt}[/tex]. The function given DOES follow this formula (At = y, -3.8 = Ao, e = 2, k = 1, t = x) so that means it is an exponential function. C cannot be the answer.

You already know that e is the base in called the "natural base". e is equal to a number around 2. In this function, they just put it as "2". So we know that the base is equal to 2.

Ao means initial value and At means value after the experiment is done. Here, we can see Ao = -3.8 so that is the initial value.

base = 2; initial value = - 3.8 >

Answer:

The sequence has common difference 3, and its general nth term can be written as:

[tex]a_n=3\,n-1[/tex]

Step-by-step explanation:

In order to define the sequence, we recall the formula for the nth term of an arithmetic sequence as:

[tex]a_n=a_1+(n-1)\,d[/tex]

where "d" is the common difference for the sequence (our unknown in this case), and the nth term is our fourth term (n = 4) which equals 11, and the first term is 2:

[tex]a_n=a_1+(n-1)\,d\\11=2+(4-1)\,d\\9=3\,d\\d=9/3\\d=3[/tex]

Therefore our sequence has common difference 3, and its general nth term can be written as:

[tex]a_n=2+(n-1)3\\a_n=3\,n-1[/tex]

The answer: -5 ≤ y ≤ 6

The range is all the possible output or y values of the function.

Our first point is at (1, 6) and our second point is at (-4, -5)

That means our y values are 6 and -5. Let's set up a compound inequality to represent our function.

-5 ≤ y ≤ 6. This means that x is greater than or equal to -5 and less than or equal to 6.

Answer:

67 degrees

Step-by-step explanation:

It is given that,

The measures of the three angles of a triangle are 43°, 70°, and xº.

We need to find the value of x.

We know that, the sum of angles of a triangle is equal to 180 degrees. Applying this theorem, we get :

[tex]43^{\circ}+70^{\circ}+x^{\circ}=180^{\circ}\\\\113^{\circ}+x^{\circ}=180^{\circ}\\\\x^{\circ}=180^{\circ}-113^{\circ}\\\\x^{\circ}=67^{\circ}[/tex]

Hence, the value of x is 67 degrees.

Answer:

The inequality is;

2x + 3y ≤ 30

Step-by-step explanation:

Here, we want to select which of the inequalities represent all possible combinations of x roses and y carnations.

From the question, we are told that roses cost $3 and carnations cost $2

So, by buying x roses, total amount spent = $3x

By buying y carnations, total amount spent = $2y

Now, we are told that she does not want to spend more than $30, this means she can spend less than $30 or exactly $30 but cannot spend more than $30

So, by mathematical convention, we say the sum of the roses and carnations bought is less than or equal to $30

Thus we have;

2x + 3y ≤ 30

Answer:

2x + 3y ≤ 30

Answer:

The probability is 0.081

Step-by-step explanation:

Here, we want to calculate the probability that the 3rd inspection will be defective.

What this means is that the first two would

not be defective.

Probability of having a defective DVD = 10% = 10/100 = 0.1

Probability of not having a defective DVD = 1 -0.1 = 0.9

So the probability of third being defective = Probability of first not defective * Probability of second not defective * Probability of third defective

= 0.9 * 0.9 * 0.1 = 0.081

Step-by-step explanation:

Because this is a multiplication equation, and we need to find one of the factors, we divide.

So 35/3=y

35/3=11.6666667

or 11.67/11.7

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The point where Andrew stops is (120,0).

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The slope of the perpendicular line will be,

m × 3 = -1

m = -1/3

Substitute the point in the line,

y = -(1/3)x + C

36 = -(1/3)12 + C

36 = -4 +C

C = 40

Now, the equation of the perpendicular line will be,

y = -(1/3)x + 40

The point will be due east, therefore, the value of y = 0,

0 =  -(1/3)x + 40

-40 = -(1/3)x

x = 120

Hence, the point where Andrew stops is (120,0).
