Answer:

[tex]\implies m\angle A =42\degree[/tex]

Step-by-step explanation:

Quadrilateral ABCD is inscribed in circle with center O.

-> Quadrilateral ABCD is cyclic.

Opposite angles of a cyclic quadrilateral are supplementay.

[tex]\implies m\angle B + m\angle D = 180\degree[/tex]

[tex]\implies (2x)\degree + (3x-5)\degree = 180\degree[/tex]

[tex]\implies (5x-5)\degree = 180\degree[/tex]

[tex]\implies 5x-5= 180[/tex]

[tex]\implies 5x= 185[/tex]

[tex]\implies x= \frac{185}{5}[/tex]

[tex]\implies x= 37[/tex]

[tex]\implies m\angle A =(x+5)\degree[/tex]

[tex]\implies m\angle A =(37+5)\degree[/tex]

[tex]\implies \huge{\orange{m\angle A =\boxed{42}\degree}}[/tex]

Answer:

600 m³

Step-by-step explanation:

The shape we have is a rectangular pyramid:

Formula: (volume of a rectangular pyramid)

Volume = (1/3) × Base Area × height

___________________________

In our case :

Base area = L × W = 20 × 18 = 360 m²

height = 5 m

⇒ Volume = (1/3) × Base Area × height

    [tex]\Longrightarrow \text{volume} \ =\ \frac{1}{3} \times 360\times 5[/tex]

[tex]\Longrightarrow \ \text{volume} \ =\ 600\ m^{3}[/tex]

Answer:

D

Step-by-step explanation:

1) if sin(ACB)=BC/BD, then BC=BD*sin(ACB);

2) m(ACB)=60°, then sin(ACB)=√3/2, then

3) BC=5/(√3/2)=10/√3 or 10√3/3.

Answer:

216 x 16

Step-by-step explanation:

Given

Simplify into prime factors.

Now, for it to be equivalent, on dividing 3456 by the product of the expression, the quotient should be 1.

Evaluating the options

18 x 8

216 x 16

24⁶

(6 x 4)⁵

216 x 16 is the correct answer

Answer:

75%

Step-by-step explanation:

Convert the fraction into a decimal number. Multiply the obtained decimal number by 100, to get a percent value.

Answer:

3/4 in a percent is 75%

Step-by-step explanation:

To change a fraction to a decimal you divide the numerator by the denominator. In this case that would be 3 divided by 4 which is 0.75, to change the decimal to a percent you move the decimal two places to the right.

Where is the question?

Answer:

The y-intercept is the point (0, 128).

The x-intercepts are the points (-4, 0) and (-8, 0).

As x → ∞, y → ∞.

As x → -∞, y → -∞.

Step-by-step explanation:

To find the y-intercept, substitute 0 for x and solve for y.

The y-intercept is (0, 128).

To find the x-intercept, substitute 0 for y and solve for x.

Set the first term, (x + 4)², equal to 0.

Set the second term, (x + 8), equal to 0.

The x-intercepts are the point (-4, 0) and (-8, 0).

Look at the degree and leading coefficient of the polynomial to determine the end behavior, and therefore you can determine how y behaves as x gets closer to infinity.

Since the degree of the polynomial is odd (3) and the leading coefficient is positive, the graph falls to the left and rises to the right.

So, as x → ∞, y → ∞ and as x → -∞, y → -∞.

If you want to verify this, plug the equation into your calculator and look at the graph. How does it behave as you look at negative x-values? How about for positive x-values?

Answer:

Answer:

3/4 simplified is 3/4 but when 2 1/4 is simplified it is 9/4. Off the bat we know there is a big difference. Also, 2 and 1/4 is irrational and 3/4 and rational.

Answer:

I believe the answerwould be 18/21.

Please let me know if I'm correct!

Hope this helps you!

Hey there!

6/7 = ?/21

= 6/7 = x/21

CROSS MULTIPLY the FRACTION

6(21) = x(7)

6(21) = 7(x)

126 = 7x

7x = 126

DIVIDE 7 to BOTH SIDES

7x/7 = 126/7

CANCEL out: 7/7 because it give you 1

KEEP: 126/7 because it help solve for the x-value

NEW EQUATION: x = 126/7

SIMPLIFY IT!

x = 18

Therefore, your answer is: 18

BECAUSE 18/21 is equivalent to 6/7 and they both give you approximately 86% (or simply 0.86) if you’re rounding your percentage/decimal form

Good luck on your assignment & enjoy your day!

Answer:

141000 * (1 - 0.016)^15 = 110699.48 = A 110700

Step-by-step explanation:

1st year depreciation = 141000 -  (141000 * 0.016) = 138744

2nd year depreciation = 138744 - (138744 * 0.016) = 136524.096

3rd year depreciation = 136524.096 - (136524.096 * 0.016) = 134339.710464

etc. unitl you reach the 15th year

Basically we calculate 1.6% of the current value of the house and subtract that from the current value for each year for 15 years.

The equation used in the answer is a faster way to approach your answer instead of calculating for each year.

You'd multiply your initial value by the difference in percentage (note well that since it is decreasing in value we subtract the decimal equivalent to 1.6% which is 0.016, from 1 where one represents 100% and then raise the difference gained to the power of the amount of years which would be 15.

Answer:

A

Step-by-step explanation:

using the quadratic formula

in the picture above

[tex]\text{Let,}\\\\~~~~~~~x=1-4i,\\\\\implies x-1 = -4i\\ \\\implies (x-1)^2 =(-4i)^2\\\\\implies x^2 -2x +1 = -16\\\\\implies x^2 -2x +1 +16 = 0\\\\\implies x^2 -2x +17=0\\\\\text{So,}~ x^2 -2x +17 ~\text{is a factor of the 3 degree polynomial.}\\ \\\text{The polynomial is,}\\\\P(x) = (x-3)(x^2 -2x +17)\\\\~~~~~~~=x^3-2x^2+17x -3x^2 +6x -51\\\\~~~~~~~=x^3 -5x^2 +23x -51[/tex]

Answer:

Riya have 20 apples

Step-by-step explanation:

Let, Tyler have x apples

Then, Riya have 5x apples

Now, From the question,

5x + x =24

or, 6x =24

or, x = 24/6

or, x = 4

Tyler have 4 apples

Again,

Riya have 5x apples

=5*4

=20

Therefore, Riya have 20 apples

Answer:

2880 ft³

Step-by-step explanation:

T o find the total amount of water that is needed to fill the pool, you have to find the volume of the pool.

Formula to find the volume of a rectangle prism is :

Volume = length × width × height

Let us solve now.

Volume = length × width × height

Volume = 36 ft × 20 ft × 4 ft

Volume = 2880 ft³

Therefore, 2880 ft³ of water is needed to fill the pool.

Step-by-step explanation:

x² - 19x + n

using the method of completing the square

add ( half the coefficient of the x- term )² to x² - 19x

x² + 2(- [tex]\frac{19}{2}[/tex] )x + (- [tex]\frac{19}{2}[/tex] )²

with n = (- [tex]\frac{19}{2}[/tex] )² = [tex]\frac{361}{4}[/tex] , then

(x - [tex]\frac{19}{2}[/tex] )² ← a perfect square trinomial
