Solve for a. 3(a+3)+6=30

Answers

Answer:

a = 5

General Formulas and Concepts:

Order of Operations: BPEMDAS

Properties: Distributive, etc.

Step-by-step explanation:

Step 1: Write equation

3(a + 3) + 6 = 30

Step 2: Solve for a

Distribute 3: 3a + 9 + 6 = 30Combine like terms: 3a + 15 = 30Subtract 15 on both sides: 3a = 15Divide 3 on both sides: a = 5

Step 3: Check

Plug in a to verify it's a solution.

Substitute: 3(5 + 3) + 6 = 30Add: 3(8) + 6 = 30Multiply: 24 + 6 = 30Add: 30 = 30

what is the tenth term in the sequence 25, 43, 61, 79, 97,....? a)187, b)151, c)133, d)115

Answers

Answer:

The tenth term would be: 187

Step-by-step explanation:

Best to make a table and apply the rule being used in order to find the pattern. The rule in this case is:

25 --- 43 --- 61 --- 79 --- 97--- ___ --- ___ --- ___ and so on

First we must find how 25 gets to 43, 61 to 79, and so on.

25 + 18 = 43

43 + 18 = 61

61 + 18 = 79

97 + 18 = 115

And you may continue this till you get to the tenth term!

6) 115

7) 133

8) 151

9) 169

10) 187

Answers

Hello!

Considering the whole book as 100%, there’s 30% left.

Then, 30% of 230 = 0,3*230 = 69 pages.

Hope you’re all right! Stay safe!

69 Pages are left to read by Tim.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total pages= 230

Percentage of reading = 70%

So, number of Pages Tim reads

= 70 /100 x 230

= 161 pages

Hence, number of pages left = 230- 161 = 69 pages

10.2 is 21.25% of what number?

Answers

Answer: 48

Step-by-step explanation: Using proportions

48 is the number whose 21.5 percent is 10.2 .

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100.

How to convert a percentage into a number?

Divide the given percentage by hundred to convert it into a number.

Let x be a number whose 21.5% is 10.2.

Therefore,

[tex]\frac{21.25}{100} (x) = 10.2[/tex]

⇒ [tex]21.25x = 10.2(100)[/tex]

⇒[tex]21.25x = 1020[/tex]

⇒[tex]x = \frac{1020}{21.25}[/tex]

⇒[tex]x = 48[/tex]

Hence, 48 is the number whose 21.5 percent is 10.2.

sin θ=√5/3, cos θ=2/3

3/2

2√5/5

√5/2

3√5/5

Answers

9514 1404 393

Answer:

cos θ = 2/3

Step-by-step explanation:

We presume you want the value of the cosine for

sin θ = √5/3 ≈ 0.745356

There are several possible approaches you can take to this problem.

1) Using the trig identity:

cos = √(1 -sin²)

cos θ = √(1 -(√5/3)²) = √(1 -5/9) = √(4/9)

cos θ = 2/3

2) Another approach you can take is to use a calculator to find the angle, then use the calculator to find the cosine of the angle.

cos θ = cos(arcsin(√5/3)) = cos(arcsin(0.745356)) = cos(48.19°) ≈ 0.666667

cos θ = 2/3

3) Yet another approach is to check the answer choices for reasonableness.

You are given sin θ = 0.745356. This is more than 0.707107, the value where sine and cosine are equal, so the cosine value must be less than 0.707. The answer choices are ...

2/3 ≈ 0.667

3/2 . . . greater than 1; not a viable cosine value

2√5/5 ≈ 0.894 . . . too large

√5/2 . . . greater than 1; not a viable cosine value

3√5/5 . . . greater than 1; not a viable cosine value

So, just looking at the values of the offered answer choices, you can choose the correct one. It is the only value with the appropriate magnitude.

Set up the long division sign with the q-7 on the outside and the 13q-91 inside.

She was distressed at the poverty of her dwelling, at the bareness of the walls, at the shabby chairs, the ugliness of the curtains. All those things, of which another woman of her rank would never even have been conscious, tortured her and made her angry. The sight of the little Breton peasant who did her humble housework aroused in her despairing regrets and bewildering dreams. She thought of silent antechambers hung with Oriental tapestry, illumined by tall bronze candelabra, and of two great footmen in knee breeches who sleep in the big armchairs, made drowsy by the oppressive heat of the stove. She thought of long reception halls hung with ancient silk, of the dainty cabinets containing priceless curiosities and of the little coquettish perfumed reception rooms made for chatting at five oclock with intimate friends, with men famous and sought after, whom all women envy and whose attention they all desire.When she sat down to dinner, before the round table covered with a tablecloth in use three days, opposite her husband, who uncovered the soup tureen and declared with a delighted air, "Ah, the good soup! I dont know anything better than that, she thought of dainty dinners, of shining silverware, of tapestry that peopled the walls with ancient personages and with strange birds flying in the midst of a fairy forest; and she thought of delicious dishes served on marvellous plates and of the whispered gallantries to which you listen with a sphinxlike smile while you are eating the pink meat of a trout or the wings of a quail.She had no gowns, no jewels, nothing.
