Answer:

The smallest number be 6.

Step-by-step explanation:

Let the 4 consecutive numbers be :

n,n+1,n+2,n+3 where n is the smallest number

Adding up the 4 consecutive numbers, we get :

n+n+1+n+2+n+3 = 4n+6

ATQ,

4n+6 = 5n

Taking like terms together,

6=5n-4n

⇒ n = 6

So, the smallest number be 6.

Answer:

to know what scale to use you divide the the highest score by the number of hozirontal line (feint/lighter drawn lines) which are 14.

so 260 ÷ 14 equals = 18.57

I then rounded the 18.57 to the nearest 10th = 20.

so the scale used is 20s

Answer:

≤ 4.3 gigabytes

Step-by-step explanation:

Flat fee + cost for x gigabytes = her budget

47 + 5 * x ≤ 68.50

5x = 68.50 - 47 ≤ 21.50

x ≤ 21.50/5 = 4.3 gigabytes

Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.

Let, "x" to represent the number of gigabytes of data Micaela can use while staying within her budget.

The total cost can be calculated by adding the flat cost of $47 to the cost based on the gigabytes used ($5 per gigabyte):

Total Cost = Flat Cost + (Cost per Gigabyte * Number of Gigabytes)

Given that Micaela wants to keep her bill at $68.50 per month, we can set up the equation:

68.50 = 47 + 5x

Now, solve for x:

68.50 - 47 = 5x

21.50 = 5x

Divide both sides by 5:

x = 21.50 / 5

x = 4.3

So, Micaela can use approximately 4.3 gigabytes of data while staying within her budget of $68.50 per month.

Step-by-step explanation:

sin = opp/hyp

The opposite side to angle A is side BC, which has a length of 60.

The hypotenuse is AB, which we can find the length of using the Pythagorean theorem. Using the Pythagorean theorem, we get that AB=100.

So the sine of A = 60/100 = 3/5

Answer:

210 mph

Step-by-step explanation:

speed of jet = x

headwind: speed = x - 27

time taken = 1134.6/(x - 27)

tailwind: speed = x + 27

time taken = 1469.4/(x + 27)

same amount of time:

1134.6/(x - 27) = 1469.4/(x + 27)

Cross multiply,

1134.6(x + 27) = 1469.4(x - 27)

1134.6x + 30634.2 = 1469.4x - 39673.8

334.8x = 70308

x = 210 mph

Answer:

x = -0.4y

Step-by-step explanation:

Simplifying

15x + 6y = 0

Solving

15x + 6y = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6y' to each side of the equation.

15x + 6y + -6y = 0 + -6y

Combine like terms: 6y + -6y = 0

15x + 0 = 0 + -6y

15x = 0 + -6y

Remove the zero:

15x = -6y

Divide each side by '15'.

x = -0.4y

Using it's concept, it is found that the relative frequency for the class with a lower class limit of 35 is of 12.5%.

A relative frequency is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, 5 out of a total of 10 + 8 + 9 + 4 + 4 + 5 = 40 students are in the class with a lower class limit of 35, hence:

f = 5/40 = 1/8 = 0.125 = 12.5%.

Sum of interior angles of a triangle = 180°

Sine rule to find side lengths:

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

----------------------------------------------------------------------

Question 1aa

Given: B = 10°, C = 100°, b = 2

10° + 100° + A = 180°

⇒ A = 70°

[tex]\dfrac{a}{\sin 70}=\dfrac{2}{\sin 10}=\dfrac{c}{\sin 100}[/tex]

[tex]\implies a=\sin 70 \cdot \dfrac{2}{\sin 10}=10.82294826...[/tex]

[tex]\implies c=\sin 100\cdot \dfrac{2}{\sin 10}=11.34256364...[/tex]

Question 2bb

Given: A = 40°, B = 40°, c = 2

40° + 40° + C = 180°

⇒ C = 100°

[tex]\dfrac{a}{\sin 40}=\dfrac{b}{\sin 40}=\dfrac{2}{\sin 100}[/tex]

[tex]\implies a=\sin 40\cdot\dfrac{2}{\sin 100}=1.305407289...[/tex]

[tex]\implies b=\sin 40\cdot\dfrac{2}{\sin 100}=1.305407289...[/tex]

Step-by-step explanation:

Note is seems typo, b = 0

Given, expression

It represents distributive property of multiplication a(b + c) = ab + ac

Correct choice is the first one

Part (a)

This sequence is convergent because all we care about are the leading terms for the numerator and denominator. As n gets really large, the leading terms dictate what happens.

The leading term up top is 9n

The leading term down below is 7n

Divide the two items to get (9n)/(7n) = 9/7

We don't have to worry about dividing by zero because n will go off to infinity, and as it does so, the sequence [tex]\{a_n\}[/tex] converges to 9/7

========================================================

Part (b)

As n heads to infinity, the terms of the sequence are approaching 9/7 (they never quite hit the exact value though).

Note how 9/7 = 1.2857 approximately which is larger than 0

So effectively for very large values of n, we're adding on 1.2857 each time or close to it, meaning that this infinite series diverges.

------

For a series like this to converge, the answer to part (a) must be 0. This way at some point, we're effectively adding 0 to the series and we approach some fixed sum.

For example, consider the sequence 1/(7n+1)

As n goes to infinity, the terms of the sequence approach 0

This means that for some very large n, the 1/(7n+1) is basically 0 and we aren't adding much onto the sum to change it. So this sum will converge to a fixed value.
