Answer:

2. el numero contante por que se suma o resta

Answer:

a) 7, 10, 13, 16, ..., 34

Step-by-step explanation:

I'll only solve part a and you'll be able to do part b.

You're given:

3n+4

to find the first four terms, just plug in n = 1, 2, 3, 4 into n.

for n=1: 3(1)+4 = 7

for n=2: 3(2)+4 = 10

for n=3: 3(3)+4 = 13

for n=4: 3(4)+4 = 16

as you might guess, to find the 10th term, you plug in n=10.

for n=10: 3(10)+4 = 34

Answer:

6

Step-by-step explanation:

[tex]-2x+6=30-6x\\\\4x+6=30\\\\4x=24\\\\x=6[/tex]

1. add 6x to both sides

2. subtract 6 from both sides

3. divide both sides by 4

Answer:

C

Step-by-step explanation:

The central angle is equal to the arc that subtends it, that is 54°

area of sector = area of circle × fraction of circle

A = πr² × [tex]\frac{54}{360}[/tex]

   = π × 10² × [tex]\frac{3}{20}[/tex]

   = 100π × [tex]\frac{3}{20}[/tex] ( cancel 20 and 100 )

   = 5π × 3

   = 15π cm² → C

Answer:

10 visits

Step-by-step explanation:

John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer.

Let the number of visits be represented as: x

For John

John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit.

The equation = $30 + $5 × x

= 30 + 5x

For Caleb

Caleb decided to go to Club4Fitness, which just charges $8 per visit.

The Equation = $8 × x

= 8x

We equate both equations to each other

30 + 5x = 8x

Collect like terms

30 = 8x - 5x

30 = 3x

x = 30/3

x = 10

Therefore, John and Caleb would spent the same amount of money after 10 visits.

Answer:

0.042

Step-by-step explanation:

Given :

p = 16% = 0.16

q = 1 - p = 1 - 0.16 = 0.84

Sample size, n = 75

The standard deviation of sampling distribution :

√(pq)/n

√(0.16 * 0.84) / 75

√0.1344 / 75

√0.001792

Standard deviation of sampling distribution = 0.0423320

Answer:

42 minutes for 21 songs

Step-by-step explanation:

My way to go about solving these is weird, so sorry in advance

76 minutes / 38 songs = 2 minutes per song,

so for 21 songs its 21x2 or 42

Answer:

Step-by-step explanation:

Answer:

q + d = 33  0.25q + 0.1d = 6 Option D

Step-by-step explanation:

The system of linear equation that can be used to find the number of quarters, q, and the number of dimes, d, Martin has is as follows:

q + d = 33

0.25q + 0.1d = 6

Martin has a combination of 33 quarters and dimes worth a total of $6.

Therefore,

q = number of quarters

d = number of dimes

0.1 dollars = 1 dime

0.25 dollars = 1 quarters

Therefore,

0.25q + 0.1d = 6

The quarters and dimes total 33. Therefore,

Therefore, the combined equation will be as follows:

q + d = 33

0.25q + 0.1d = 6

Answer: 50.24

Step-by-step explanation:

The equation to find the area of a circle is pi*r^2. First, r^2 is 4^2 which is 16.  Then times pi. Assuming pi in this case is 3.14, 3.14 times 16 is 50.24.

Sorry I couldn’t find the answer, I hope this will do.

So, what you are supposed to find here is the surface area of this rectangular prism. So the answer is 52 units of the special reflective material is needed.

Since total surface area of a rectangular prism = 2(lb + bh + hl)

Where l = length of the ice block

b = width of the ice block

h = height of the ice block

Now total surface area for the given dimensions = 2(4×2 + 2×3 + 3×4)

= 2(8 + 6 + 12)

Answer:

Step-by-step explanation:

We know the value of cos 360° is always equal to 1.

Answer:

cos(360 + x) = cos x

Proof:

cosine identity:

cos(x + y) = cosxcosy - sinxsiny

or

cos(360 + x) = cos360cox - sin360sinx

but

cos360 = 1 and sin360 = 0

Therefore,

cos(360 + x) = cos x
