Answer:
84 degrees
Step-by-step explanation:
Applying the Cosine Rule (Choice 2 is the correct one) :-
12^2 = 11^2 + 6^2 - 2*11*6 cos Y
144 = 121 + 36 - 132 cos Y
cos Y = (121 + 36 - 144) / 132
cos Y = 0.09848
Y = 84.3 degrees

[tex](2n) + (2n) +( n + 5) + (n + 5) + (3n + 3) \\ = 2n + 2n + n + 5 + n + 5 + 3n + 3 \\ = \boxed{9n + 13}✓[/tex]
(9n+13) is the right answerSolve the equation: 3(–2x+1)–2(x+13)=7x–4(1–x)
Step-by-step explanation:
3(–2x+1)–2(x+13)=7x–4(1–x)
-6x+3 - 2x+26 = 7x-7x²-4-4x
-8x +29 = -7x²-3x-4

Answer:
Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?
Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?
Step-by-step explanation:
2/3 × 18
Checking all options
Sarah mixed 18 ounces of orange juice with 23 ounce of pineapple juice. How many ounces of juice did she have in all?
Ounces of orange juice = 18
Ounces of pineapple juice = 23
Total ounces of juice = 18 + 23
= 41 ounces
A container held 18 ounces of water. Two-thirds of the water leaked out of the container. How many ounces of water were left in the container?
Total water in the container = 18
Water leaked out = 2/3
Ounces of water left = 18 - 2/3(18)
= 18 - 36/3
= 18 - 12
= 6
Jordan had 18 coins. Two-thirds of the coins were dimes. How many coins were dimes?
Total Number of coins = 18
Dimes = 2/3 of 18
Number of dimes = 2/3 × 18
= 36 / 3
= 12
Min had 18 quarters. He used 2/3 of the quarters to play arcade games. How many quarters did Min use?
Total quarters = 18
Quarters used for game = 2/3 × 18
= 2/3 × 18
= 36 / 3
= 12

A photo that measure 5 inches in length by 7 inches in width is enlarged to 7.5 inches in length. What is the width?
Answer:
10.5
Step-by-step explanation:
You can use ratios to solve this problem.
The original dimensions of the photo is
5 in. by 7 in.
This can be written as:
5:7
And the next is 7.5:?
Then you can use ratios to solve this.
5:7=
7.5:?
5*1.5=7.5 so you can multiply the other side by the same thing. 7*1.5=10.5
The width is 10.5 inches.

Convert the following decimal to vulgar fraction
0.dot285
HELP
Answer:
[tex]\displaystyle 0.285=\frac{57}{200}[/tex]
Step-by-step explanation:
Decimal to Fraction Conversion
We have the decimal number 0.285
It can be expressed as:
[tex]\displaystyle 0.285=\frac{285}{1000}[/tex]
The fraction can be simplified by dividing by 5:
[tex]\displaystyle 0.285=\frac{57}{200}[/tex]
Since 57 and 200 have no more common factors, this is the simplified equivalent fraction.
[tex]\mathbf{\displaystyle 0.285=\frac{57}{200}}[/tex]

Answer:
Sn = n^2+4n, and n = 11
Step-by-step explanation:
Sorry that i'm late, but i think i see what you did wrong here;
What you entered in as that Sₙ = 2n + 3, but instead the nth term (aₙ) was equal to 2n + 3. How? Well you know the following formula;
aₙ = a₁ + (n-1)d
here the difference = 2 & a₁ = 5
aₙ = 5 + 2(n-1) = 5 + 2n - 2 = 2n + 3
So the aₙ = 2n + 3, not Sₙ. The sum of the series would be calculated using the following formula:
Sₙ = n/2[2a₁ + d(n-1)]
= n/2[2(5) + 2(n-1)] = n^2+4n
Now then we have to determine n where the series sum is 165. Let's plug in this value;
165 = n^2 +4n,
n = 11 & n = -15
n has to equal 11 here

A number line goes from 0 to 60. A line is drawn from 2 to 60.
Genevieve is cutting a 60-inch piece of ribbon into a ratio of 2:3. Since 2 inches are frayed at one end of the ribbon, she will need to start 2 inches in. This is indicated as 2 on the number line.
25.2 in.
29.4 in.
35.1 in.
40.7 in.
Answer:
25.2
Step-by-step explanation:
I just got it right on edge.
The location of Genevieve's cut will be at; 25.2 in
We are told that she is cutting a 60 inch piece of ribbon into a ratio of 2:3.Now, 2 inches are frayed at one end of the ribbon and she starts 2 inches in with 2 indicated on the number line. Thus;length available for her to cut = 60 - 2 = 58
Now, the ratio is 2:3. Thus, the length of the parts will be; 2/5 and 3/5.She starts the counting from the frayed end. Thus, the point of cutting will be;
2/5 × 58 = 23.2
Now, since the number line starts from 0 to 60, we will begin our counting from 0 and since she skipped 2 numbers which is the 2 inches that was frayed, we will add 2 to 23.2 to get the exact place her cut will be located. Thus;Location of cut = 2 + 23.2
Location of cut = 25.2 inches

The perimeter of a rectangle is 56 cm. The length of the rectangle is 2 cm more than the width. Find the dimensions of the rectangle.
Length: ____
Width: ____
Answer:
Rectangles! Nice.
Step-by-step explanation:
This is a very simple problem. Let's first represent the width of the rectangle as the variable x.
Then, we know that the length of the triangle is x+2. See where I'm going with this?
The formula for the perimeter of an rectangle is [tex]P=2*Length+2*Width[/tex].
All we have to do next is just input our values for the length and width, and you'll be golden!
[tex]56=2(x+2)+2(x)\\56=4x+4[/tex]
Next to subtract 4 from both sides and then to divide by 4!
[tex]52=4x\\x=13[/tex]
There's your answer! Don't know why Brainly is bugged right now.
NOTE: If you can't read the answer above, the width is 13cm. This also means that the length is 15cm.
