Answer:

So, the answer for b is 20.

The way to figure this out is:

angle N is congruent to angle S

angle M is congruent to angle M

side NM is 10

because of the three things above, triangle NHM is congruent to triangle SML because of SAS(side angle side postulate)

Hi!

Pi: The number π is a mathematical constant. It is defined as the ratio of a circle's circumference to its diameter, and it also has various equivalent definitions. It appears in many formulas in all areas of mathematics and physics. It is approximately equal to 3.14159.

Hope this Helps!

Yours Truly,

Answer:

the amount of water she drinks is x, the mileage is y:

   x          y          

2 miles     5 oz

4 miles     10 oz

6 miles     15 oz

the ratios would be 4/10 and 6/15

Step-by-step explanation:

for every 2 miles Holly runs, she drinks 5 oz of water, right? the ratio is 5:2, so if you were to come up with other numbers that match the ratio, they have to be divisible by the parts of the ratio. so if she runs 2 miles, she drinks 5 oz. if she runs 4 miles, then she drinks 10 oz.

think of a ratio like a fraction (in this case it would be 2/5). if you were to make equivalent ratios, then the two fractions would have to be equal, right? well, when you simplify all of the numbers listed in the table above after making them into fractions, they would all go back to 2/5, so the numbers i came up with above are equivalent ratios, meaning they have the same value when simplified.

hopefully that helps and isn't too confusing! if you need other help, let me know! :)

i just used a calculator-

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

=

The factored form of the expression would be; (7x + 2√5) (7x - 2√5)

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to factor the expression form 49x² + 20

Therefore, 49 is a perfect square,

This expression could also be given as;

(7x)²- (2√5)²

Now, we know that:

a²- b² = (a + b) (a - b)

Now plug the values then we have:

(7x)²- (2√5)² = (7x + 2√5) (7x - 2√5)

Hence, the factored form of the expression would be; (7x + 2√5) (7x - 2√5)

The factored form of the expression 49x² + 20 will be (7x - 2i√5) and (7x + 2i√5). Then the correct option is B.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The expression is given below.

⇒ 49x² + 20

The expression can be written as,

⇒ 49x² - 20i²

Simplify the expression, then we have

⇒ 49x² - 20i²

⇒ (7x)² - (2i√5)²

⇒ (7x - 2i√5)(7x + 2i√5)

The factored form of the expression 49x² + 20 will be (7x - 2i√5) and (7x + 2i√5). Then the correct option is B.

Step-by-step explanation:

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

Hence, the statement that the blue radius is perpendicular to the green cord is false

Answer:

s=40w+350; s=$1,070

Step-by-step explanation:

Our equation looks like this:

s=40w+350

Next we plug in 18 for w, our number of weeks.

s=40(18)+350

Multiply the 40 and 18.

s=720+350

Add the 350 and 720.

s=1,070

Add a dollar sign to say that the amount is in dollars.

s=$1,070

HTH :)

The equation relating the total amount of money in the savings account, S and the number of weeks Yoko has been adding the money, W is given by S = 350 + 40W.

Total amount of money in the savings account after 18 weeks is

An equation is a statement in mathematics which includes two algebraic expressions or numbers relating with an equal sign.

There are left hand side and right hand side for every equation and may or may not include variables.

S is the total amount of money in the savings account of Yoko.

W is the number of weeks Yoko has been adding money.

Initial money = 350

After 1 week total money = 350 + (1 × 40)

After 2 weeks, total money = 350 + (2 × 40)

It goes on like this until the last week.

So after W weeks total money = 350 + (W × 40)

Total amount of money in the savings account after W weeks, S = 350 + 40W.

After 18 weeks, S = 350 = (40 × 18) = $1070

Hence the equation relating W and S is, S = 350 + 40W.

Total amount of money after 18 weeks = $1070
