How many different 5-digit PIN codes are there that only include the digits 7, 2, 4, 6, 9 and 3?

Answer:

Acute triangle

Step-by-step explanation:

All the three angles of the triangle is less than 90, all angles are acute. So, it is acute triangle.

If any one of the three angles is 90, then it is right triangle.

If any one of the three angle is more than 90, then it is obtuse triangle.

Answer:

c four tenths

Step-by-step explanation:

tenths are the first space after the decimal.

option C does not represent the decimal 0.004

A number system is defined as a system of writing to express numbers.

Given,

Decimal number is 0.004

zero point zero zero four.

We need to find the following does NOT represent this decimal

A. four thousandths

4/1000=0.004

B. 4/1,000

0.004

c.  four tenths

4/10=0.4

D. 1/250=0.004

Hence, option C does not represent the decimal 0.004

Answer:

True.

Step-by-step explanation:

It is given that, a regular hexagon is dilated by a scale factor of 0.4 to make image.

It means, the perimeter of image is 0.4 times the perimeter of the original hexagon.

For example,

Let's take the rectangle with length of 12 and width of 4, it's perimeter is 12+12+4+4 =32

Let's find image using scale factor 0.4, we get

length =0.4(12)= 4.8

width =0.4(4)=1.6

So, perimeter of image = 4.8+4.8+1.6+1.6=12.8

If we compare the perimeters

0.4(32)=12.8.

So, it is true.

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

probability (P) is calculated as

P = [tex]\frac{favourableoutcome}{numberofpossibleoutcomes}[/tex]

Here favourable outcome is a purple brick

number of possible outcomes = 6 + 5 + 4 = 15

P(purple brick ) = [tex]\frac{6}{15}[/tex] = [tex]\frac{2}{5}[/tex]

Answer: 17/21

Step-by-step explanation:

Number of cities = 42

Fraction of cities that has lake = 5/42

Fraction of cities that have rivers = 29/42

The fraction of these 42 cities that have a lake or river running through them will then be:

= 5/42 + 29/42

= 34/42

= 17/21

Pythagorean theorem: [tex]a^{2}+b^{2}=c^{2}[/tex]

Answer:

B

Step-by-step explanation:

Pythagorean theorem states that a²+b²=c²

Through observation, I assumed that 8 was the hypotenuse

I sqaured both the known lengths of the leg and hypotenuse and plugged them into the equation: a²+36=64

I subtracted 36 from 64 leaving me with 28=a²

Then in order to isolate the variable I had to apply square root to both values, cancelling the "²" and leaving me with √28=a

Answer: 60 is the answer.

Step-by-step explanation: We can use the total sum, 180.

To get the missing angle, add the 2 angles, 60 and 60.

60 + 60 = 120.

Then subtract from 180.

180 - 120 = 60.

Hence, 60 is the answer.

Let me know if you have any questions.

Note to asker: Write this down!

To find 1 missing angle:

A1 + A2 = TA - 180 = X (A1 = Angle1)

Answer:

27°

Step-by-step explanation:

I'm assuming you have learned basic trigonometry: SOH CAH TOA. In this diagram to find the angle x we are given the opposite side and the hypotenuse, therefore we will use SOH. sinθ = opp/hyp. Plugging in those values we get sinθ = 5/11 -> θ = sin⁻¹ (5/11) = 27.03569179° = 27°

Answer:

4

Step-by-step explanation:

okay since there was a 50% INCREASE, 6 is (100%+50%) greater than last months amount.

100%+50%=150%=1.5

let's say that x is last months amount

6=1.5x

x=6/1.5

x=4

There were 4 musicians in the band last month.

[tex]\sqrt[7]{3^{2}}[/tex]

Step-by-step explanation:

[tex]3^{2/7}[/tex]

^ That is 3 to the 2/7ths power. We know that. Now it needs to be in radical form. That takes a bit of thinking.

If you have a power that is less than one (like 1/2) it is can be written as a root. So say you're given [tex]2^{1/2}[/tex]. That is the same exact thing as saying [tex]\sqrt{2}[/tex]. It's the same thing. You can say it either way.

In the same way, a squared power, like [tex]2^{2}[/tex], is the same as representing it like a fraction, like [tex]2^{2/1}[/tex]. They both mean the same thing.

So by pointing these out, a fraction power = the power / the root.

If that makes sense.

So, with this in mind, let's look at what we have again.

[tex]3^{2/7}[/tex]

So we can split it up to say that 3 is raised to a 2nd power times a 1/7th power.

So we know what a 3 to the 2nd power is: [tex]3^{2}[/tex].

And since we have a fraction that's also included, we now know that is a root. So we can represent that like this: [tex]\sqrt[7]{3}[/tex].

But those two answers need to be combined. We can do that like this: [tex]\sqrt[7]{3^{2}}[/tex]

Answer: [tex]\sqrt[7]{3^{2}}[/tex]

So there it is! I hope that helped you!!
