What is the solution of -3x -12>3

[tex]\text{The angle from the right is 30}^\circ \\ \\ \text{We use sinus theorem:}\\\\ \dfrac{y}{\sin(60)^{\circ}} = \dfrac{8}{\sin(30)^{\circ}} \Rightarrow \dfrac{y}{\dfrac{\sqrt{3}}{2}} = \dfrac{8}{\dfrac{1}{2}} \Rightarrow y = \dfrac{\sqrt 3}{2}\cdot 16\Rightarrow \boxed{y = 8\sqrt 3}[/tex]

Answer:

y = 8[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the tangent ratio in the right triangle and the exact value

tan60° = [tex]\sqrt{3}[/tex], hence

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{y}{8}[/tex]

Multiply both sides by 8

8 × tan60° = y, so

y = 8[tex]\sqrt{3}[/tex] ← exact value

Answer:

14.14

Step-by-step explanation:

You can find the value of x using the trig ratio Sine = opposite/hypotenuse.

The sin 45 = 10/x. Solve for x.

x= 10/ sin45

x = 10/0.707

x = 14.14

Answer:

Perimeter of Total Area = 18.4(2) + 32.5(2) = 101.8 meters

Area of Seating Space = 178 squared meters

Step-by-step explanation:

Perimeter of Total Area = 18.4(2) + 32.5(2) = 101.8 m

Seating Space = 18.4*32.5 = 598

Basketball Court = 15*28 = 420

598 - 420 = 178

[tex]\frac{3}{8}[/tex] cups of oil

Step-by-step explanation:

Given : A recipe requires 1/4 cup of oil for every 2/3 cup of water.

To Find:  How much oil (in cups) is needed per cup of water?

Solution:

Oil required by [tex]\frac{2}{3}[/tex] cup of water = [tex]\frac{1}{4}[/tex]

Oil required by 1 cup of water = [tex]\frac{\frac{1}{4}}{\frac{2}{3}}[/tex]

                                                   = [tex]\frac{3}{8}[/tex]

Hence [tex]\frac{3}{8}[/tex] cups of oil is needed for per cup of water.

The oil required for one cup of water is 3/8 cup.

Given that a recipe requires 1/4 cup of oil for every 2/3 cup of water.

The quantities of oil and water are given in fractions. We can write as,

[tex]\dfrac {1}{4}cup \; oil = \dfrac {2}{3} cup\;water[/tex]

[tex]1 cup\;water = \dfrac {\dfrac {1}{4}cup\;oil}{\dfrac{2}{3}}[/tex]

[tex]1cup\;water = \dfrac {3}{8}cup\;oil[/tex]

Hence we can conclude that the oil required for one cup of water is 3/8 cup.

Answer:

62.5% of the class

Step-by-step explanation:

If 12 students is 3/8 of the class, the ones who earned A's, then 5/8 did not earn A's.

Let c represent the total number of students in the class.

Then (3/8)c = 12, and c = (8/3)(12) = 32.

5/8 of these 32 students did not earn A's:  (5/8)(32) = 20.

These 20 students constitute 20/32 of the class, or 0.625 of the class, or 62.5% of the class.

Answer:

Part 1) The value of x is [tex]2\sqrt{7}\ in[/tex]

Part 2) The value of y is [tex]\sqrt{21}\ in[/tex]

Step-by-step explanation:

Part 1

Find the value of x

Applying Pythagoras Theorem

[tex]8^{2}=x^{2} +6^{2}[/tex]

[tex]x^{2}=8^{2}-6^{2}[/tex]

[tex]x^{2}=28[/tex]

[tex]x=2\sqrt{7}\ in[/tex]

Part 2

Find the value of y

Applying Pythagoras Theorem

[tex]7^{2}=x^{2} +y^{2}[/tex]

substitute the value of x

[tex]7^{2}=28 +y^{2}[/tex]

[tex]y^{2}=7^{2}-28[/tex]

[tex]y^{2}=21[/tex]

Answer:

The slope is 1

Step-by-step explanation:

The slope of the line is also its gradient. A gradient is basically rise/run

In this case the rise is one and the run is also one if you look at the graph...therefore 1/1 equals 1

Just by eyeballing the graph, you could see that the slope is 1: whenever x increases by 1, y will also increase by 1. Since the slope is defined as the ratio of the increments along the y and x axis, we have 1/1=1.

If you want to be more formal, you can pick any two points on the line, for example (0,1) and (3,4), and use the formula

[tex]m = \dfrac{\Delta y}{\Delta x} = \dfrac{y_2-y_1}{x_2-x_1} = \dfrac{4-1}{3-0} = 1[/tex]

Answer:

90 sq. ft.

Step-by-step explanation:

The formula you need to use is length*width*height. If you plug the numbers given into the equation, you get 5*3*6. Multiply this for the answer.

Answer:  The correct option is (B) 126 sq. feet.

Step-by-step explanation:  We are given to find the total area of the solid figure.

We can see that the given solid figure is a cuboid.

The total area of a cuboid with length l units, breadth b units and height w units is given by

[tex]A=2(lb+bh+hl).[/tex]

For the given cuboid, we have

length, l = 5 feet,

breadth, b = 3 feet and

height, h = 6 feet.

Therefore, the total area of the given cuboid will be

[tex]A=2(5\times 3+3\times6+6\times 5)=2(15+18+30)=2\times63=126~\textup{sq. feet}.[/tex]

Thus, the total area of teh solid figure is 126 sq. feet.

Option (B) is CORRECT.

Answer:

Q1. is 628 cm

Q2 18.84 cm

Step-by-step explanation:

Q1. 400 / 2 = 200 to get the radius

3.14 * 200 = 628

Q2. 12 / 2 = 6 to get the radius

31.4 * 6 = 18.84

$3.468.15

I just subtracted 1.89% from $183,500

$3,468.15.

To calculate Patrick's annual property taxes on his new home, we need to apply the property tax rate of 1.89% to the value of the home. The formula to calculate this is:

Property Taxes = Home Value  imes Tax Rate

In this case, Patrick's home value is $183,500 and the tax rate is 1.89%. So, the calculation would be:

Property Taxes = $183,500 times 0.0189

When we perform this multiplication, we get:

Property Taxes = $3,468.15

Therefore, the property taxes on Patrick's new home are $3,468.15.

Step-by-step explanation:

Given a straight line segment AB with points A, O, and B, and angle measures <COA, <COD, and <DOB, we find <COD to be 45 degrees using angle sum properties.

In the given scenario, we have a straight line segment AB, and points O, A, and B lying on it. We are required to find the measure of angle COD, denoted as <COD. According to the information provided, <COA is (3x + 94), <COD is (x + 36), and <DOB is (2x - 4).

Since A, O, and B are collinear, the sum of the angles around point O must be 180 degrees. Therefore, <COA + <COD + <DOB = 180 degrees. Substituting the given angle measures into the equation, we get:

(3x + 94) + (x + 36) + (2x - 4) = 180.

Combining like terms and solving for x:

6x + 126 = 180,

6x = 54,

x = 9.

Now that we have the value for x, we can find <COD by substituting it into the expression (x + 36):

<COD = 9 + 36 = 45 degrees.

Therefore, the measure of angle COD is 45 degrees.

Hello there!

An equation to model the number is: n - 7 x 2 = 2

To find the equation, break apart the question.

twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2

twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.

twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.

The value of the number based on the information given is 8.

Let the number be represented by x.

Since we are given the equation that twice the difference of a number and 7 equals 2, the equation to solve this will be:

2(x - 7) = 2

2x - 14 = 2

2x = 2 + 14

2x = 16

x = 16/2

x = 8

The value of the number is 8

Step-by-step explanation:

angle A and the diameter form an isosceles right triangle, with OA as the hypotenuse and r as the other sides. You can then make and solve an equation from the Pythagorean Theorem:

r^2 + r^2 = 14^2

2r^2 = 14^2

2r^2 = 196

r^2 = 98

r = √98

Answer:

[tex]P (B) = 0.6[/tex]

Step-by-step explanation:

We have the Venn diagram that shows the probabilities of occurrence of 3 events A, B and C

In this case, since events A and B and B and C are non-disjoint events, then the probability of occurrence B is the sum of the probability that only B will occur plus the probability of occuring A and B plus the probability that B and C occur

This is:

[tex]P (B) = 0.1 +0.3 +0.2[/tex]

[tex]P (B) = 0.6[/tex].

Answer:

Option C is false.

Step-by-step explanation:

The correct answer is:

C. Polynomials are closed under division. When you divide polynomials, the result will always be a polynomial.

This is false because sometimes when we divide polynomials, one polynomial does not gets completely or evenly divided by the other.  

In such cases, we get a remainder which is not a monomial as the variable has a negative power. This means the quotient is not a polynomial.

We can show this by example : suppose we want to divide

[tex]x^{-6}[/tex]by [tex]x^{2}[/tex]

=> [tex]\frac{x^{-6} }{x^{2} }[/tex]

=> [tex]x^{-6-2}[/tex] =>[tex]x^{-8}[/tex]

This is not a polynomial. So the closure property does not hold true for division of polynomials.
