Calculate the speed of a wave with a frequency of 2 Hz, amplitude of 3m, and a wavelength of 10m

Answers

Speed = wavelength * frequency
10 * 2 = 20
The speed is 20 m/s

The speed of a wave is the product of the wavelength and its frequency.

The speed of the wave is 20m/s

Given

[tex]\lambda = 10m[/tex] --- the wave length

[tex]f =2Hz[/tex] --- the frequency

[tex]A = 3m[/tex] --- the amplitude

The speed of wave (v) is calculated as follows:

[tex]v =f\lambda[/tex]

Substitute values for f and [tex]\ambda[/tex][tex]\lambda[/tex]

[tex]v = 2Hz \times 10m[/tex]

[tex]v = 20ms^{-1}[/tex]

Hence, the speed of the wave is 20m/s

a triangle has a base of 16 inches and a height of 1/8 inches what is the area ​

Answers

Answer:

the area is 2

Step-by-step explanation:

The area of the triangle will be 1 inch².

What is a triangle?

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angle of a triangle is always equal to 180°.

Given that the height of the triangle is 1/8 inches and the base of the triangle is 16 inches. Therefore, the area of the triangle will be,

Area of the triangle = 0.5 × Height × Base

                                 = 0.5 × (1/8) inches × 16 inches

                                 = 1 inch²

Hence, the area of the triangle will be 1 inch².

A teacher surveyed her class about their online accounts and wanted to know if they had “Fb” accounts or if they had “Snap ” accounts. The Venn diagram shows her results. If a person from the class is randomly selected, what is the probability that the person has a “Fb” account but not a “Snap” account

a)1/5
b)16/25
c)7/25
d)18/25

Answers

Answer:

a) 1/5

Step-by-step explanation:

There are 25 students total in the class.

Therefore, the probability that the person has a “Fb” account but not a “Snap” account is 5/25 or 1/5.

The school of business has 3 fax machines. The toner in each machine needs to be changed after about 5 hours of use. There is one unit secretary who is responsible for the fax machine maintenance. It takes him 15 minutes to replace the toner cartridge. What is the probability that 2 fax machines need toner at the same time?

Answers

Answer:

That is an indeterminant question, as we do not know the amount of fax time used of each machine and it certainly won't be equal. However, based on whats given you could say

Step-by-step explanation:

5 hrs. use / 0.25 service time = 20 / 3 machines = 6.67. Probability of needing to service 2 machines simultaneously is: 1/6.67 = 15%.

The Probability of needing to service 2 machines simultaneously is 15%.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

The school of business has 3 fax machines.

and, It takes him 15 minutes to replace the toner cartridge.

So, 5 hours / 0.25 service time

= 20 / 3 machines

= 6.67.

Then, the Probability of needing to service 2 machines simultaneously

= 1/6.67

= 15%.

Hence, the probability is 15%.

. Leslie is blowing up one of her favorite photographs to hang on her wall. If the photo's original length and height were 8 inches and 15 inches, and the new height is 4 feet, how many feet must the new picture be

Answers

Answer:

[tex]L_2 = 2\frac{2}{15}\ ft[/tex]

Step-by-step explanation:

Given

Original

[tex]Length(L_1) = 8\ in[/tex]

[tex]Height (H_1) = 15\ in[/tex]

New

[tex]Height (H_2) = 4\ ft[/tex]

Required

Determine the new length (L2)

Since the original photographs was blown up; the original and the new photographs would have the same ratio

i.e.

[tex]Ratio = L_1 : H_1[/tex]

and

[tex]Ratio = L_2 : H_2[/tex]

Equate both ratios

[tex]L_1 : H_1 = L_2 : H_2[/tex]

Rewrite as fraction

[tex]\frac{L_1}{H_1} = \frac{L_2}{H_2}[/tex]

Substitute values for L1, H1 and H2

[tex]\frac{8}{15} = \frac{L_2}{4}[/tex]

Multiply both sides by 4

[tex]4 * \frac{8}{15} = \frac{L_2}{4} * 4[/tex]

[tex]4 * \frac{8}{15} = L_2[/tex]

[tex]\frac{4 * 8}{15} = L_2[/tex]

[tex]\frac{32}{15} = L_2[/tex]

[tex]2\frac{2}{15} = L_2[/tex]

[tex]L_2 = 2\frac{2}{15}\ ft[/tex]

The new length must be [tex]2\frac{2}{15}\ ft[/tex]

The new picture must be [tex]2\frac{2}{15}[/tex] feet or 2.1334 feet in length.

We know, [tex]1\ inch= \frac{1}{12}\ feet[/tex]

Given to us:

Initial length, [tex]L_i =8 inches[/tex];

Initial height, [tex]H_i =15\ inches[/tex];

Final height, [tex]H_f = 4\ feet[/tex];

We know that a when a picture is blown up(enlarged), it is always done in a specific ratio, therefore

Ratio, [tex]r=\dfrac{Length}{Height}[/tex]

So,

[tex]\dfrac{Initial\ Length}{Initial\ Height} =\dfrac{Final\ Length}{Final\ Height}[/tex],

[tex]\dfrac{8}{15} =\dfrac{Final\ Length}{4}\\\\{Final\ Length}=\dfrac{8}{15} \times 4 \\\\{Final\ Length}=\dfrac{32}{15}\\\\{Final\ Length}=2\frac{2}{15}\ feet[/tex]

Hence, the new picture must be [tex]2\frac{2}{15}[/tex] feet or 2.1334 feet in length.

x=34

Step-by-step explanation:

2x =68

-----------             (68 divided by 2 is 34)

2        2

x=34

Answer:

the answer would be A. x=34

Step-by-step explanation:

to solve for x in this equation, you need to get x all by itself to do this, you need to remember that what you do to one side of the equation, you must do to the other. so:

we start with 2x=68, and to get rid of the 2 in front of the x, divide each side by 2.

2x/2=68/2

so now x is alone:

x=68/2

and now divide 68 by 2, which is 34.

so, x=34
