Answer:

2.4 seconds

Step-by-step explanation:

It is given that,

The time for one swing is proportional to the square root of the length of the string.

\(T\propto \sqrt{L}\)

or

\(\dfrac{T_1}{T_2}=\sqrt{\dfrac{L_1}{L_2}}\) ....(1)

We have,

L₁ = 64 cm, T₁ = 1.6 s, L₂ = 144 cm, T₂ = ?

Substitute all the values in formula (1).

\(T_2=\dfrac{T_1}{\sqrt{\dfrac{L_1}{L_2}}}\\\\T_2=\dfrac{1.6}{\sqrt{\dfrac{64}{144}}}\\\\T_2=2.4\ s\)

So, the new time period of the simple pendulum is 2.4 seconds.

114 is 95% of 120

100% of 120 is 120, therefore 95 percent of 120 equals 114. To learn how to solve 114 is 95 percent of what number, see the step-by-step instructions below.

114 is 95 Percent of What Number?

Formula = Number x 100

Percent = 114 x 100

95 = 120

The following shows the steps to derive this formula and find out 95% of the number is 114.

Step 1: If 95% of a number is 114, then what is 100% of that number? Set up the equation.

114

95% = Y

100%

Step 2: Solve for Y

Using cross multiplication of two fractions, we get

95Y = 114 x 100

95Y = 11400

Y = 11400

100 = 120

On each roll of a 6-sided die, we have 6 possible outcomes.

Then if we roll it twice, we will have 36 outcomes.

The outcomes where the sum is 4 are:

roll 1     roll 2    sum

1             3           4

3            1            4

2           2           4

Son in 3 out of 36 outcomes the sum can be 4, then the probability opf rolling a sum of 4 is given by the quotient:

P = 3/36

P = 1/12

Answer:

-33

Step-by-step explanation:

so your problem is 10(4-7)-(4-1)

The first thing you should do is solve what's in the parenthesis

so the first one 4-7 equals -3

and the second one 4-1 equals 3

Now you can write your equation again with the new answers

10(-3)-3  

Now multiply the 10 with the number in the parenthesis

10x-3= -30

Now write it again

-30-3

now just do -30 minus 3

That will give you -33

Solution :

Given :

There are five cities in a network and the cost of \(\text{building}\) a road directly between \(i\) and \(j\)  is the entry \(a_{i,j}\)

\(a_{i,j}\)  refers to the matrix.

Road cannot be built because there is a mountain.

The given matrix :

\(\begin{bmatrix}0 & 3 & 5 & 11 & 9\\ 3 & 0 & 3 & 9 & 8\\ 5 & 3 & 0 & \infty & 10\\ 11 & 9 & \infty & 0 & 7\\ 9 & 8 & 10 & 7 & 0\end{bmatrix}\)

The matrix on the left above corresponds to the weighted graph on the right.

Using the \(\text{Kruskal's algorithm}\) we can select the cheapest edge that is not creating a cycle.

Starting with 2 edges of weight 3 and the edge of weight 5 is forbidden but the edge is 7  is available.

The edge of the weight 8 completes a minimum spanning tree and total weight 21.

If the edge of weight 8 had weight 10 then either of the edges of weight 9 could be chosen the complete the tree and in this case there could be 2 spanning trees with minimum value.

Answer:

-2x + 3y = 6

Rearrange

-2x + 3y - 6 = 0

ax + by + ca = 0

a = -2

b = 3

If ca was a typo, and you meant c, then c = -6.

However, if ca wasn't a typo, then:

ca = -6

-2c = -6

c = -6 / -2

c = 3

The probability that a randomly selected cat has no treatment and no fleas is 43/87.

It is a branch of mathematics that deals with the occurrence of a random event.

Total number of cats = (cats sprayed with flea deterrent + cats with no treatment)

= (33+6 + 43+5)

=87

we need to find the number of cats with no treatment and no fleas, and divide it by the total number of cats.

Now we can see that the number of cats with no treatment and no fleas is 43.

Therefore, the probability that a randomly selected cat has no treatment and no fleas is:

P(no treatment and no fleas) = number of cats with no treatment and no fleas / total number of cats

= 43 / 87

Hence, the probability that a randomly selected cat has no treatment and no fleas is 43/87.

Answer: P(z>1.33) = 0.0918

Explanation:

On a normal curve, the areas are to the left. Thus.

P(z>1.33) = 1 - P(z < 1.33)

From the normal distribution table, the probability value corresponding to a z score 1.33 is 0.9082

P(z>1.33) = 1 - 0.9082

P(z>1.33) = 0.0918

Using trigonometry we know that option (B) "cosθ < 0" is correct.

For a right-angle triangle, the sum of the square of the legs is equal to the hypotenuse side(longest side).

Therefore, for a right triangle

For the triangle that has a² + b² > c², it shows it is not a right triangle.

Cosine law:

Substitute the value then we get:

Subtracting c² on both sides of the inequality:

Adding 2abcosθ on both sides then we get:

cosθ is negative in the second quadrant and third quadrants.

Therefore, using trigonometry we know that option (B) "cosθ < 0" is correct.

Linear equations are equation that has a leading degree of 1. Given the expression below:

5(3x − 15) + 16 = 5x + 11

Expand the expression

5(3x) - 5(15) + 16 = 5x + 11

15x - 75 + 16 = 5x + 11

15x - 5x - 59 - 11 = 0

10x - 70 = 0

10x = 70

Divide both sides by 10

10x/10 = 70/10

x = 7

Hence the value of x makes the equation true is 7

Answer:

n>=6

Step-by-step explanation:

1-0.4ⁿ>=0.99

1-0.99>=0.4ⁿ

0.4ⁿ<=0.01

Apply log10:

Log10(0.4ⁿ)<=log10(0.01)

n×log10(0.4)<=log10(0.01)=-2

Because log10(0.4)=-0.39794 is negative we get:

n>=5.028.

Since n is integer, we have n>=6

The answer will be 57. You may ask, why? The answer is actually 56.5. Don't let B fool you. Since 56.5 is more than 56, B is wrong. However,  you can take the remaining masks and store them in the 57th package. So C is correct.
