Answers

Answer 1

Answer:

First question: a

Second: d

Third: b

Fourth: a

Fifth: a

Sixth: b

Step-by-step explanation:

Ask me if you need an explanation for any of the questions because there isn't much to explain for rounding.

Fifth: The reason that the answer is not b is because the 6 in that equation should have a - (if it was a typo, the answer should be b)

Darlene wants to buy a sweater that originally cost 32$ it is on sale for 20% off. Sales tax is 6.75%. What is the final price of the sweater with the discount and tax

Answers

Answer:

$27.34

Step-by-step explanation:

32 x 0.20 = $6.40

32 - 6.4 = $25.60

25.6 x .0675 ≈ 1.738

25.6 + 1.738 = 27.338 ≈$27.34

Triangles ABC and d e f are similar the lengths of the sides of ABC are 56/64 and 72 the length of the largest side of d e f is 252 what is the length of the smallest side of d e f

Answers

Answer:

[tex]D E F = 196[/tex]

Step-by-step explanation:

Given

[tex]ABC = 56, 64\ and\ 72[/tex]

[tex]Largest\ of\ D E F = 252[/tex]

Required

Determine the smallest side of DEF

Since both sides are similar, then the sides of DEF can be calculated using:

[tex]D E F = k * ABC[/tex]

First, we need to solve for k

From the given parameters

[tex]D E F = 252[/tex] when [tex]ABC = 72[/tex]

This is so because these are the largest sides of both triangles respectively

[tex]D E F = k * ABC[/tex]

[tex]252 = k * 72[/tex]

Divide through by 72

[tex]252/72 = k * 72/72[/tex]

[tex]k=252/72[/tex]

[tex]k=3.5[/tex]

We make use of the same formula to determine the length of the smallest side.

The smallest of ABC is 56, so we have:

[tex]D E F = k * ABC[/tex]

[tex]D E F = 3.5 * 56[/tex]

[tex]D E F = 196[/tex]

Hence, the smallest side of DEF is 196

Answers

let 4units represent 800g, since the ratio of the masses is 7:5:4, with 800g being the lightest.

1 unit = 800/4 = 200g
hence, the mass of the heaviest cake will be 7 units, which is 7 x 200g = 1400g

Step-by-step explanation:

Given that,

The length of a baseball is 29 inches

Logan thinks he can bring the baseball bat home in his suitcase.

The length of the suit case is 24 inches while the height is 18 inches. We can find the diagonal (x) of the suitcase using Pythagorean Theorem as follows :

[tex]x^2=24^2+18^2\\\\x=\sqrt{900} \\\\x=30\ \text{inches}[/tex]

The diagonal of the suitcase is 30 inches. It means that he can put the baseball bat in the suitacse easily.

Diane earns $14,500 a year. She pays 11% of her gross income for federal, state, and local taxes. She is taxed at the FICA rate of 7.65%. She has 3.5% of her income withheld for personal deductions. She is paid biweekly. What is her net pay for each pay period? Round to nearest cent.

Answers

Answer:

$434.16346

Step-by-step explanation:

Given that :

Gross earning= $14500

Federal, state and local taxes = 11%

0.11 * $14500 = $1595

FICA tax rate = 7.65%

0.0765 * 14500 = $1109.25

Personal deduction :

3.5% * 14500

0.035 * 14500 = $507.50

Total deduction :

$(1595 + 1109.25 + 507.50)

= $3211.75

Net earning : $(14500 - 3211.75) = 11288.25

Since she is paid bi weekly:

Number of biweeks in a year = 52 /2 = 26

Number of payments per annum = 26

Hence,

Net pay per period :

11288.25 / 26

= $434.16346

Polynomial Identities

So, you want even more proof? Well then lets just substitute in values for a, b, and x. Lets make a=2, b=4, and x=6.

(ax+b) (x+a) = ax^2 +a^2x +bx +ab

(ax+b) (x+a)

+bx +ab

(ax+b) (x+a)=ax^2 +a^2x +bx +ab

This identity is effective and easy to use!

The New Identity

To solve this you have to use the distributive property, more specifically FOIL

Use FOIL on first term

ax^2+a^2x+bx+ab

Answers

The statement that the blue radius is perpendicular to the green cord is false

From the complete question,

The blue radius does not bisect the green chord

This means that the blue radius and the green chord do not meet at 90 degrees

Since both lines do not meet at 90 degrees, then they are not perpendicular
