LG LED TV
Your price =

Answers

Answer: $264

Steps:
1. Change 20% into a decimal. by moving decimal two places to the left.
.20

2. 330 * .20 = 66
20% of 330 is 66 meaning $66 will be discounted from the tv’s original price.

3. 330 - 66 = 264

330 - original price of tv
20% (.20) - discount
264 - price of tv after discount

Equation used to solve: 330 - (330 * .20)

A triangle has sides of lengths 9,7, and 12. Is it a right triangle? Explain.
no: 92 + 7 + 122
O yes: 92 + 72 122
O no: 92 + 7 = 122
yes: 92 + 7 = 122

Answers

Answer: No, it is not a right triangle.

Explanation:
9^2 + 7^2 (?) 12^2

81 + 49 (?) 144

130 = 144

Since 12^2 = 144, and the square root of 130 is 11.4^2, it is not a right triangle.

write any two quadratic equations.

Answers

To find:

Any two quadratic equations.

Solution:

The general form of a quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Where, a,b and c are real number and a is non zero.

We know that a,b,c can take any values but a cannot be 0.

For a=1, b=1,c=1, we get

[tex]1x^2+1x+1=0[/tex]

[tex]x^2+x+1=0[/tex]

One quadratic equation is [tex]x^2+x+1=0[/tex].

For a=3,b=-1,c=5, we get

[tex]3x^2+(-1)x+5=0[/tex]

[tex]3x^2-x+5=0[/tex]

Therefore, the two quadratic equations are [tex]x^2+x+1=0[/tex] and [tex]3x^2-x+5=0[/tex].

Answers

The error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

What is the Side-side-side Congruence Theorem (SSA)?

The SSA congruence theorem only exist and holds true, only if the congruence non-included angles in both triangles are either obtuse or right angles and have two pairs of congruent sides.

Thus:

The two triangles given have a pair of non-included congruent angles that are less than 90 degrees.

Therefore, the error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

What is the measure of ZXZY?

Answers

Answer:

measure of angle XZY = 52 degrees

Step-by-step explanation:

The sum of measure of angles of a circle is 360 degrees.

therefore, m(arc XY) = 360 - (110 + 146)

m(arc XY) = 360 - 256

= 104 degrees

angle XZY is an inscribed angle.

By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the intercepted arc.

So, m( angle XZY) = 1/2 * 104

= 52 degrees.

The number of bacteria in a petri dish is 50,000 (on day 0) if the amount is doubling each day by when will the number of bacteria be 400,000. Let x represent the number of days and f(x) represent the amount of bacteria. Write an equation.

Answers

Answer:

f(x) = 50000*2^x3 days

Step-by-step explanation:

Given:

Initial amount of bacteria = 50000Growth rate = 2 times a day

Required equation:

f(x) = 50000*2^x

Solve for x:

400000 = 50000*2^x2^x = 400000/500002^x = 82^x = 2^3x = 3

After 3 days bacteria numbers will reach 400000

Find the value of the marked angles in each of the following ( see image ).

Please show workings.

The only given angle is 126°.

The angle to look for is marked by “))”

Answers

Answer:

117°

Step-by-step explanation:

The central angle is twice the inscribed angle (same arc).

The inscribed angle forms a supplementary angle with the missing one (opposite angles of the cyclic quadrilateral).

The missing angle is:

180° - 1/2(126°) = 180° - 63° = 117°

Tan^2/1-tan+cot/1-tan=cot+tan+1 prove that

Answers

It looks like you have

tan²(x) / (1 - tan(x)) + cot(x) / (1 - tan(x)) = cot(x) + tan(x) + 1

but this is not an identity.

Take for instance x = 3π/4. Then

tan(3π/4) = -1

cot(3π/4) = -1

so that

tan²(x) / (1 - tan(x)) + cot(x) / (1 - tan(x)) = 0

while

cot(x) + tan(x) + 1 = -1

and of course 0 ≠ -1.

Find the approximate area of the triangle y x> O 30 square units O 15 square units 21 square units 45 square units

Answers

Answer:

Step-by-step explanation:

a right triangle is half of a rectangle and the area of a rectangle is

area of rectangle = length × width

Area of a triangle is one half times the length times the width

area of triangle = 1/2 × length × width

in this case

length is the number of the y units

width is the number of x axis unit

area of triangle = 1/2 × length × width

area of triangle = 1/2 × (y units) × (x units) you need to count and insert

the number of units into the
