Answer 2

Answer:

75 degrees and 105 degrees.

Step-by-step explanation:

So this is a transversal. We can use a couple different methods to solve this. We can use many different theorems to solve this problem. So we know that m<2=m<4 because of vertical angles, we also know that m<4=m<6 because of alternate interior angles. We also know that m<6=m<8 because of vertical angles. So we know that m<2=m<4=m<6=<8. In a transversal, there are only two different measurements. And those two different measurements add up to 180 degrees. So since once of the measurements is 75, that means the other measurement has to be 105 degrees. Also, we see that m<4 and m<5 are same side interior angles and according to that theorem, they have to equal up to 180 degrees.

a square room has a floor area of "100" square feet. the height of the room is 6 feet what is the area of one wall

Answers

Answer:

Its 60

Step-by-step explanation: 10x10=100 so 10x6=60

Did that help you???

The area of one wall of the square room is 60 sq. feet.

What is the area of a square?

The area of a square is the square of its side.

If the length of a side of a square is a unit, then its area is

Area = a² sq. units.

How to solve the question?

In the question, we are informed that a square room has a floor area of 100 sq. feet, and its height is 6 feet.

We are asked to find the area of one wall.

The floor of the room is given a square. We let the length of the side of that square be 'a' units.

Then, its area is a² sq. units.

We are given that the area of the floor is 100 sq. feet.

So, we can write the equation as:

a² = 100 sq. feet,

or, a = 10 feet.

The height of the room is given as 6 feet.

Therefore, the area of a wall is 10*6 sq. feet = 60 sq. feet.

As the floor is rectangular in shape, with dimensions 10 and 6.

Therefore, the area of one wall of the square room is 60 sq. feet.

PLEASE HELP! FIND THE AREA

Answers

Answer:

All you need to do is split the shape so that you can find the individual area

Step-by-step explanation:

So we first split the shape so we get a triangle...

A=1/2bhB=2H=4A=1/2*2*4A=4

Now we split the shape again to get another square...

A=lwA=2*4A=8

Then we find the area of the other square...

A=lwA=2*5A=10

Our last step is to add all the areas together

we let TA represent Total areaTA=4+8+10TA=22

Hence the area is 22

Answers

The linear equation is given by y = 15x. A person earns $600 for working 40 hours

What is a linear equation?

A linear equation is in the form:

y = mx + b

Where y, x are variables, m is the rate of change and b is the y intercept.

The line passes through (7, 105) and (8, 120), hence:

y - 105 = [(120 - 105)/(8-7)}(x - 7)

y = 15x

For 40 hours:

y = 15(40) = $600

if the person got a $50 bonus and also worked some hours, it would change the graph

two years ago the cats tim and tom were toghether 15 years old.Now tom is 13 years old.In how many years will tim be 9 years old?

Answers

Answer:

3 years

Step-by-step explanation:

As with many age problems, you can reason it without equations. If Tom is 13 now, 2 years ago he was 11. If the total age of the two cats at that time was 15, then Tim was 15 -11 = 4.

That means Tim is now 4+2 = 6, so will be 9 in 3 years.

_____

Additional comment

If you want to write equations, there are several ways you can do it. We often like to use variables to represent the current age. We can assign ...

x = Tim's current age; y = Tom's current age.

The sum of their ages 2 years ago was ...

(x -2) +(y -2) = 15

Tom's current age is 13, so we have y=13. Using that in the equation gives ...

x -2 +13 -2 = 15

x = 6 . . . . . . . . . . subtract 9, collect terms

That's Tim's current age, so Tim will be 9 years old in 3 years.

Hello,

so y-intercept is (0,30)

The product of the roots are -30 = 2 * 5 * -3, and the sum is 4 = 2 + 5 - 3 , so we can factorise

[tex]f(x)=x^3-4x^2-11x+30 \\\\f(x)=0 \\\\<=> x^3-4x^2-11x+30=(x+3)(x-2)(x-5)=0\\\\<=> x=-3 \ or \ x=2 \ or \ x=5[/tex]

[tex]g(x) = 5x^2[/tex]

Step-by-step explanation:

In the equation x^2, when x = 1, y = 1. But in g(x), when x is 1, y is 5. Since g(x) is a scaled version of x^2, we can conclude that g(x) is 5 times x^2.

Therefore, [tex]g(x) = 5x^2[/tex].

Avoiding an accident when driving can depend on reaction time. That time, measured in seconds from the moment the driver see danger until they step on the brake pedal, can be described by the Normal model with a mean of 1.5 seconds and a standard deviation of 0.18 seconds.

Note that this scenario is talking about a population distribution. There is no discussion of a sample or sample size. Therefore, you do not need to adjust the standard deviation that is given before using the normalcdf and invNorm commands.

a) What percent of drivers have a reaction time greater than 1.8 seconds?

Give the command and values you used as a way of showing your work:

Give your final answer rounded to 2 decimal places:

b) Describe the reaction time of the slowest 10% of all drivers? (Hint: The slower a person reacts, the higher their reaction time so this is looking at the right tail of the distribution)

Give the command and values you used as a way of showing your work:

Give your final answer rounded to 2 decimal places:

Answers

Using the normal distribution, it is found that:

a) 4.75% of drivers have a reaction time greater than 1.8 seconds.

b) The reaction time is of at least 1.73 seconds.

Normal Probability Distribution

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem, the mean and the standard deviation are given by, respectively:

[tex]\mu = 1.5, \sigma = 0.18[/tex]

Item a:

The proportion is one subtracted by the p-value of Z when X = 1.8, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1.8 - 1.5}{0.18}[/tex]

[tex]Z = 1.67[/tex]

[tex]Z = 1.67[/tex] has a p-value of 0.9525.

1 - 0.9525 = 0.0475 = 4.75%.

4.75% of drivers have a reaction time greater than 1.8 seconds.

Item b:

The reaction time is of at least X seconds, in which X is the 90th percentile, that is, X when Z = 1.28, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 1.5}{0.18}[/tex]

[tex]X - 1.5 = 1.28(0.18)[/tex]

[tex]X = 1.73[/tex]

The reaction time is of at least 1.73 seconds.
