Step-by-step explanation:

Here, we want to write an inequality

we should beat it in mind that, the greater the angle that a side of a triangle faces, the greater its length will be relatively

as we can see, the side NM faces the greater angle of 83, relative to the side LN that faces the angle of 56;

So we can conclude that;

The probability that Jamil will be late for work is 0.2.

Work out the probability that Jamil will not be late for work.

Answers

Given:

The probability that Jamil will be late for work is 0.2.

To find:

The probability that Jamil will not be late for work.

Solution:

We have,

P(Jamil will be late) = 0.2

We know that,

P(Jamil will not be late) = 1 - P(Jamil will be late)

                                       = 1 - 0.2

                                       = 0.8

Therefore, the probability that Jamil will not be late for work is 0.8.

The Richter scale magnitude reading m is given by m=log10x , where x represents the amplitude of the seismic wave causing ground motion. Determine the reading of an earthquake that is 10 times less intense than an earthquake that measures 4.5 on the Richter scale.

Answers

Answer: The reading would be 5.5 on the Richter scale.

Step-by-step explanation:

The intensity of an earthquake that measures 4.5 on the Ritcher scale can be found by solving:

4.5 = log₁₀(x)

for x.

remember that:

logₐ(x) = ln(x)/ln(a)

Then we can rewrite our equation as:

4.5 = ln(x)/ln(10)

4.5*ln(10) = ln(x)

we also know that:

ln(exp(x)) = exp(ln(x)) = x

Then we can apply the exponential equation to both sides to get:

exp( 4.5*ln(10)) = exp( ln(x) ) = x

exp( 4.5*ln(10)) = x

x = 31,622.8

Now, if we have an intensity 10 times larger than this, we will have:

x = 10*31,622.8 = 316,228

The reading on the Richter scale will be:

m = Log₁₀(316,228) = 5.5

It says solve for the variable I do t understand

Louis makes a model of a plane.

The wingspan of the model is 50 centimetres.
The wingspan of the real plane is 80 metres.

Work out the scale of the model.
Give your answer in the form 1:n

Answers

Answer:

1 : 1.6

For every centimeter on the model, it is 11.6 centimeters on the real plane

Step-by-step explanation:

The required value of the scale of the model in the form of 1:160.

Given that,

The wingspan of the model is 50 centimeter,

The wingspan of the real plane is 80 meter.

We have to determine,

The scale of the model and give your answer in the form 1 : n.

According to the question,

The wingspan of the model =  50 centimeter [tex]= \frac{50}{100} = 0.5m[/tex]

The wingspan of the real plane is 80 meter.

The ratio of the scale = 1:n

Therefore,

The equation of proportion is,

[tex]\frac{wingspan \ of \ the \ model}{wingspan\ of \ the \ palne} = \frac{1}{n}[/tex]

Putting all the values in the equation,

[tex]\frac{0.5}{80} = \frac{1}{n} \\\\n = \frac{1 \times 80}{0.5} \\\\n = 160[/tex]

The value of n = 160.

Hence, The required value of the scale of the model in the form of 1:160.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

A mixed expression, also known as a complex fraction, is a fraction that contains a fraction in the numerator, the denominator, or both the numerator and the denominator.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Nine identical cakes weigh a total of 20¼ pounds.

20(¹/₄) = 20.25

20.25/9 = 2.25

Two groups are hiking at about the same speed . Mario’s group hikes for 2.5 hours Seemas group hikes for 4.7 hours and covers 8.8 more miles . How fast are the kickers going ? Solve the equation below to find out . 4.7x=2.5x+8.8

Answers

Answer: 18.8 miles

Step-by-step explanation:

Ww are given the equation 4.7x=2.5x+8.8 to solve the question. This will be:

4.7x = 2.5x + 8.8

Collect like terms.

4.7x - 2.5x = 8.8

x = 8.8/2.2

x = 4

To know how fast the kickers are going will be

4.7x = 4.7 × 4 = 18.8 miles

How can you find the town with a temperature that is the opposite of -4°C? Name the town with that temperature

Which town answers the question

From the attachment, the temperature of town J is -4°C.

This can be represented as:

[tex]J = -4^{\circ}C[/tex]

The opposite of -4 is 4.

So, the town with the temperature that is opposite of -4°C must have a temperature of 4°C.
