Answer:

[tex]a)\\x=12\\y=12\sqrt{3}[/tex]

Step-by-step explanation:

The angle without a numerical value is 30°

Using the 30-60-90 rule:

Since we know that 2a is the side with length 24

[tex]2a=24\\a=24/2\\a=12\\x=12[/tex]

To find y

[tex]y=a\sqrt{3}\\a=12\\y=12\sqrt{3}\\[/tex]

We can conclude -

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

y = mx also represents direct proportionality. We can write [m] as -

m = y/x

OR

y₁/x₁ = y₂/x₂

Given is a straight line.

The equation of a straight line is written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Now, from this we get -

m = -A/B     {Slope}

c = - C/A     {y - intercept}

So, the equation will be -

y = mx + c

We can also calculate slope by -

m = (y₂ - y₁)/(x₂ - x₁)

Therefore, we can write -

m = -A/B   → unit rate of change of [y] with respect to [x].

c = - C/A   → the point where the graph cuts the [y] axis.

Equation  → y = mx + c

Answer:

The discount is 43.75 dollars.

Step-by-step explanation:

125 - 81.25 = 43.75

Final answer:

The discount percentage applied to reduce the original price of $125 to the sale price of $81.25 is 35%.

Explanation:

A student is trying to find out the discount percentage that was applied to an item originally priced at $125 to have a final sale price of $81.25. To calculate the discount, one can use the formula: Discount percentage = ((Original Price - Sale Price) / Original Price)  imes 100%. Applying this to the given values: ($125 - $81.25) / $125  imes 100% = $43.75 / $125  imes 100% = 35%. Thus, the discount percentage applied is 35%.

Answer:

11/12 is Z

Step-by-step explanation:

Do you need the explanation?

The required value of z is 11/12 in the given equation.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

The equation is given in the question as:

1 3/4 + z = 2 2/3

We have to determine the value of z in the given equation,

As per the question, we have

⇒ 1 3/4 + z = 2 2/3

Convert the mixed numbers into fractions,

⇒ 7/4 + z = 8/3

Rearrange the terms in the above equation,

⇒ z = 8/3 - 7/4

Take LCM in the term of fractions,

⇒ z = (32 - 21)/12

⇒ z = 11/12

Therefore, the required value of z is 11/12 in the given equation.

the subtraction property of equality

Step-by-step explanation:

Given

8x + 15 = 11x + 2

Subtract 15 from both sides of the equation

8x + 15 - 15 = 11x + 2 - 15

8x = 11x - 13

Answer:

the addition property of equality

Step-by-step explanation:

Compare step 1 with step 2 in the solution process:

step 1: -5x = -4x - 15

step 2: -x = -15

The variable was isolated on the left side of the equation by adding 4x to both sides. This is justified by the addition property of equality.

Answer:

In circle D, angle ADC measures (7x + 2)°. Arc AC measures (8x - 8)°.

Circle D is shown. Points A, B, and C are on the circle. Point C is on the opposite side of points A and C. LInes are drawn from point A to point B, from point B to point C, from point C to point D, and from point D to point A. Angle A D C measures (7 x + 2) degrees. Arc A C measures (8 x minus 8) degrees.

What is the measure of Angle A B C ?

36° *****

43°  

72°  

144°

Step-by-step explanation:

its 36°

Applying the central angle theorem, the measure of angle ABC is: a. 36°

Given:

m∠ADC = (7x + 2)° (central angle)

measure of intercepted arc AC = (8x - 8)°

Therefore:

(7x + 2)° = (8x - 8)°

7x + 2 = 8x - 8

8 + 2 = 8x - 7x

10 = x

x = 10

Thus:

m∠ABC is an inscribed angle = half of measure of intercepted arc AC

m∠ABC = 1/2(8x - 8)°

m∠ABC = 1/2[8(10) - 8]

m∠ABC = 36°

Answer:

8 gallons of gasoline costs $30.63.

Step-by-step explanation:

Set up a proportion to solve for x, or the cost of 8 gallons of gasoline. The $47.86 goes on top of the first ratio, and 12.5 goes on top of the second. This is because the $47.86 is the cost of the 12.5 gallons of gasoline. Next, put x on the bottom of the first ratio and 8 on the bottom of the second ratio. This is because the amount of money you are trying to find, x, is the cost of the 8 gallons of gasoline. The proportion should look like this: [tex]\frac{47.86}{x} = \frac{12.5}{8}[/tex]

To solve the proportion, use cross multiplication. To do that, multiply 8 by 47.86 to get 382.88. Then, divide 382.88 by 12.5. The answer is 30.6304‬, so round to the nearest cent to get a total of $30.63.

Answer:

144

Step-by-step explanation:

48×3= 144

48×3=144

to make it easier just add the number being multiplied the amount of times its being multiplied.

48+48+48=144

Both 3x48 and 48x3 yield the same result, which is 144, because multiplication is commutative.

Both expressions involve multiplying the numbers 3 and 48.

In the first expression, 3x48 means you're multiplying 3 by 48. This gives you 144, because 3 times 48 equals 144.

In the second expression, 48x3 means you're multiplying 48 by 3. This also gives you 144, because multiplication is commutative, which means the order of the numbers doesn't change the result. So, whether you multiply 3 by 48 or 48 by 3, you'll always get the same answer, which is 144.

So, to summarize:

3x48 = 144

48x3 = 144

Both expressions result in the same value of 144.

Answer:

C) They are perpendicular lines.

Step-by-step explanation:

We first need to find the slope of the graph of the lines passing through these points using:

[tex]m = \frac{y_2-y_1}{x_2-x_1} [/tex]

The slope of the line that passes through (−12, 15) and (4, −5) is

[tex] m_{1} = \frac{ - 5 - 15}{4 - - 12} [/tex]

[tex]m_{1} = \frac{ - 20}{16} = - \frac{5}{4} [/tex]

The slope of the line going through (−8, −9) and (16, 21) is

[tex] m_{2} = \frac{21 - - 9}{16 - - 8} [/tex]

[tex] m_{2} = \frac{21 + 9}{16 + 8} [/tex]

[tex]m_{2} = \frac{30}{24} = \frac{5}{4} [/tex]

The product of the two slopes is

[tex]m_{1} \times m_{2} = - \frac{4}{5} \times \frac{5}{4} = - 1[/tex]

Since

[tex]m_{1} \times m_{2} = - 1[/tex]

the two lines are perpendicular.
