There are 7 friends that want to ride together but only 4
open seats in the car. What is the probably that a specific
friend gets a spot in the car?

Answer:

the answer is 130 because why not

Answer:

The answer is 7.33 m

Answer:

40-29=n

Step-by-step explanation:

You have 29 in total yall have 40

so to find ur friends we subtract

Answer:

Step-by-step explanation:

your pennies + your friends pennies = the total number of pennies between you two

so the equation would be :

29 + n = 40

(im not sure if you wanted it solved for n but here is the solution just in case)

29 + n = 40

n = 40 - 29

n = 11

Answer:

x = 2

Step-by-step explanation:

Note that 25 = 5² , then

[tex]5^{(6-2x)}[/tex] = 5²

Since the bases on both sides are 5 then equate the exponents

6 - 2x = 2 ( subtract 6 from both sides )

- 2x = - 4 ( divide both sides by - 2 )

x = 2

Answer:

D

Step-by-step explanation:

Using the tangent ratio in the right triangle

tanθ = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{7}{4}[/tex] , then

θ = [tex]tan^{-1}[/tex] ([tex]\frac{7}{4}[/tex] ) ≈ 60° ( to the nearest degree )

Answer:

Option B is true

Step-by-step explanation:

The formula for Cos is Adjacent/hypotenuse. 12 is Adjacent to angle e, and 17 is the hypotenuse.

Answer:

B: cos e = 12/17

Step-by-step explanation:

When using the SOHCAHTOA method you can see that Cos is adjacent over hypotenuse and in the triangle diagram they give you the measurements of the hypotenuse and the adjacent only, so you know that they would be using the cos equation.

Answer:

56.52

Step-by-step explanation:

1. multiply your r by 2

so 9*2= 18

2. multiply that by pi, which you substitute 3.14 in for

so 18*3.14=56.52

Radius ( r ) = 9 inches

Circumference of the Circle ?

Circumference of the Circle = 2πr

Putting the value of r in the formula -

[tex] = 2\pi r[/tex]

[tex] = 2 \times \frac{22}{7} \times 9[/tex]

[tex] = 56.5 \: inches[/tex]

[tex] \mathsf \pink {Hence, \: the \: circumference \: of \: the \: circle \: is \: 56.5 \: in.}[/tex]

Answer:

The frequency of note E is:

f(E) = 330 Hz

The frequency of note C is:

f(C) = 262 Hz

The ratio of the frequency of note E to the frequency of note C is just the quotient of these two frequencies:

r  = f(E)/f(C) = 330Hz/262Hz = 330/262 = 1.26

Now, we want to find how man E waves will fit in the length of four C waves.

Note that here the word "length" is used, so we need to work with the wavelengths, not with the frequencies.

For waves, we have the relationship:

v = f*λ

where:

v = velocity (in this case, velocity of the sound = 343 m/s)

f = frequency

λ = wavelength.

So, the length of a single E wave is:

λ(E) = (343 m/s)/(330 1/s) = 1.04 m

And the length of a single C note is:

λ(C) = (343 m/s)/(262 1/s) = 1.30 m

In four C waves, the length is:

4*λ(C) = 4*1.30m = 5.2m

The number of E waves that fit in the length of four C waves is equal to the quotient between the length of four C waves and one E wave:

N = (4*λ(C))/(λ(E) ) = (5.2 m)/(1.04m) = 5.14

So we can fit 5 E waves into four C waves.

Answer:

The ratio of the frequency of E to C can be found by dividing the frequency of E by the frequency of C:

330 Hz / 262 Hz ≈ 1.26

To express the answer in a simple integer ratio, we can divide both 330 Hz and 262 Hz by their greatest common factor, which is 2:

330 Hz / 2 = 165 Hz

262 Hz / 2 = 131 Hz

So the ratio of the frequency of E to C is:

165 Hz / 131 Hz = 15/12 ≈ 1.25

This ratio is approximately equal to 5/4

Therefore, the answer is (A) 5 to 4

the answer is -4 because it is smaller than -3 and greater than -5

Answer:

-4

Answer:

  f(x) = (π-2)x^2/4

Step-by-step explanation:

The area of the triangle is ...

  A = 1/2(x)(x) = (1/2)x^2

The hypotenuse of the triangle is x√2, so the radius of the circle is x/√2. That means the area of the semicircle is ...

  A = 1/2πr^2 = (π/2)(x/√2)^2 = (π/4)x^2

The shaded area is the difference between the semicircle area and the triangle area.

  f(x) = (π/4)x^2 -(1/2)x^2

  f(x) = (π-2)x^2/4

Correct question:

a sequence U1, U2,U3...... is defined by the relation [tex]U_{n +1} = 2U_n +5[/tex]. if U1 =2, find U2​ and U3

Answer:

U2 = 9

U3 = 23

Step-by-step explanation:

Given sequence;

[tex]U_{n +1} = 2U_n +5[/tex]

U1 = 2

U2 = ?

[tex]U_{n +1} = 2U_n +5\\\\U_2 = 2(U_1) + 5\\\\U_2 = 2(2) + 5\\\\U_2 = 4 + 5\\\\U_2 = 9[/tex]

Solving for U3;

[tex]U_3 = 2(U_2) + 5\\\\U_3 = 2(9) + 5\\\\U_3 = 18 + 5\\\\U_3 = 23[/tex]

Answer:

Quarter pounder has -580 calories and the Whooper has

1589 calories

Step-by-step explanation:

Let x represent quarter pounders and y represent the Whoppers.

2 QP and 3 Whoppers provide 3607 calories and one of each provide 1009. so let set up the system

[tex]2x + 3y = 3607[/tex]

[tex]x + y = 1009[/tex]

Apply subsitution method

[tex]y = 1009 - x[/tex]

[tex]2x + 3(1009 - x) = 3607[/tex]

[tex]2x + 3027 - 3x = 3607[/tex]

[tex] - x + 3027 = 3607[/tex]

[tex] - x = 580[/tex]

[tex]x = - 580[/tex]

Plug the system back into one of the equations and we get

[tex]y = 1589[/tex]
