Answer:

Step-by-step explanation:

Recursive sequences generally look like this:

a1 = something

an= ahhhhhh

The 1st term in this sequence is 11.

So we have

a1=11

And now we see that each term is adding by 22.

We have,

a1=11

[tex]a_{n} =a_{n-1}+22[/tex]

Answer:

20π cubic units

Step-by-step explanation:

The volume of a cylinder is the area of the base x height.

The area of a circle is π r^2 squared.

So the area of the base is π ⋅ 2^2 = 4π

The height of the cylinder is 5, so the volume is 4π ⋅ 5 = 20π cubic units

Answer:

y=2x+5

Step-by-step explanation:

If you graph it you can figure out the starting point of the parallel line.

The rate of change is 2 and since the point the parallel line needs to pass through is (-1,3) you need to shift the starting point (y-intercept) up by 10 units.

Shifting the y-intercept of y=2x-5 up by 10 makes the new line y=2x+5.

54 = z

z + 45 = 99

Answer:

508 because you need to add up all the sides

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

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of single cone ice cream and let y represent the number of double cone ice cream.

Since the vendor stocks a maximum of 70 single cones and a maximum of 45 double cones. hence:

0 < x ≤ 70, 0 < y ≤ 45      (1)

The vendor expects to sell no more than 50 ice creams, hence:

x + y ≤ 50

Plotting the constraint using geogebra online graphing tool, we can see that the solution to the problem is at (5, 45)

Since the vendor sells single-cone ice-creams for $3 and double-cone ice-creams for $4.50, hence:

Revenue = 3x + 4.5y

At the point (5, 45), the revenue is:

Revenue = 3(5) + 4.5(45) = $217.5

Answer:

Mean= sum/no.

= 35+77+80+86+87+90+94+100 / 8

= 649/8

=81.125 was the mean

Median: the middle number

35, 77, 80, 86, 87, 90, 94, 100

Both are in the middle so: 86+87/2

=173/2

=86.5 as the median

Step-by-step explanation:

followed: 35, 77, 80, 86, 87, 90, 94, 100

calculate the mean and median of this data set

Answer:

134°

Step-by-step explanation:

[tex] In\: \odot O,[/tex] AB and AC are tangents at points B and C respectively. OB and OC are radii.

[tex] \therefore OB\perp AB\: \&\: OC\perp AC[/tex]

(By tangent radius theorem)

[tex] \therefore m\angle ABO =m\angle ACO = 90\degree [/tex]

[tex] m\angle CAB+ m\angle ABO +m\angle ACO+ m\angle BOC = 360\degree [/tex]

[tex]\therefore 46\degree + 90\degree +90\degree+ m\angle BOC = 360\degree [/tex]

[tex]\therefore 226\degree + m\angle BOC = 360\degree [/tex]

[tex]\therefore m\angle BOC = 360\degree-226\degree [/tex]

[tex]\therefore m\angle BOC = 134\degree [/tex]

[tex]\implies m\angle O= 134\degree [/tex]

sorry if inorrect

Answer:

A) <SQT = 36 degrees

B) <QRW = 36 degrees

C)<PRV = 72 degrees

Step-by-step explanation:

A) <SQT = 36 degrees (< SQT and < PQR are vertically opposite angles, and vertically opposite angles are equal)

B) <QRW = 36 degrees ( <QRW and < SQT are corresponding angles since they lie on the same side of the transversal across the parallel lines. Corresponding angles are equal)

C)<PRV = 72 degrees( <PRV is the exterior base angle to < PQR and exterior base angles, are always twice their interior correxpondents)

Answer:

n=0

Step-by-step explanation:

Let's solve your equation step-by-step.

10n+0.3=0.1n+0.3

Step 1: Subtract 0.1n from both sides.

10n+0.3−0.1n=0.1n+0.3−0.1n

9.9n+0.3=0.3

Step 2: Subtract 0.3 from both sides.

9.9n+0.3−0.3=0.3−0.3

9.9n=0

Step 3: Divide both sides by 9.9.

9.9n/ 9.9 = 0/ 9.9

n=0

Answer:

n=0

Answer:

0

Step-by-step explanation:

10n - .1n = 9.9n

9.9n + .3 = .3

subtract .3 from the other one and get 0

9.9n = 0 then divide and it comes out to 0

Answer:

6

Step-by-step explanation:

The range of a data set is the numbers covered by the data. This means that the range is the difference between the minimum and maximum. The minimum is the smallest point, 2, and the maximum is the largest point, 8. Therefore, since 8-2=6, 6 must be the range.
