c=___? HELP!

Answer:

178 text messages

Step-by-step explanation:

You have do 7.05 times 3 and you get 21.15. Then you do 26.70 minus 21.15 and you get 5.55. Then you do 7.05 divided by 47 then you get 0.15.  SO each messages is 0.15 cents so you do 0.15 times 37 and you get 5.55 and then you add 21.15 and 5.55 and you get 26.70. Then you take 141 and add it to 37 and you get 178 as your answer          

The post office is 3 miles west of your home. Your school is 2 miles north of the post office therefore the distance of the home from your school is 3.6mile.

This is referred to as the length of the space between two points and is usually measured in miles or meter.

We were given sides 3 miles west and 2 miles north and the distance will be the hypotenuse of the formed triangle.

c² = a² + b²

c² = 3² + 2²

c² = 9 + 4 = 13

c = √13 = 3.6miles.

The measures of the angles are ∠1 = 127°, ∠2 = 53°, ∠3 = 127°, ∠4 = 37°, ∠5 = 53°, ∠6 = 90°, ∠7 = 37°, ∠8 = 143°, ∠9 = 37° and ∠10 = 143°

From the question, we have the following parameters that can be used in our computation:

The transversal lines and the other lines

So, we have

∠1 = 180 - 53

Evaluate

∠1 = 127°

Also, we have

∠5 = 53°

By vertical angles, we have

∠2 = 53°

∠3 = 127°

Next, we have

∠4 = 127 - 90°

∠4 = 37°

Solving further, we have

∠6 = 90°

By corresponding angles, we have

∠7 = 37°

∠9 = 180 - 90 - 53°

∠9 = 37°

∠10 = 90 + 53°

∠10 = 143°

∠8 = 143°

The simplified form of the expression 9²- (b + c)²/{c² - (a - b)²} is {81 - b² - c² - 2bc}/{c² - a² - b² + 2ab}.

A term is a single mathematical phrase. It might consist of only one variable—a letter—one number—positive or negative—or several variables multiplied but never added or subtracted. A number is placed in front of some nouns that have variables. Coefficients are numbers that come before phrases.

Given:

Two quadratic polynomials,

9²- (b + c)² and c² - (a - b)².

And the expression, according to the question,

9²- (b + c)²/{c² - (a - b)²}

In order to simplify the expression,

we have to expand the quadratic polynomial.

So,

(b + c)² = b² + c² + 2bc.

And (a - b)² = a² + b² -2ab.

Substituting the value of (b + c)² and (a - b)² to the expression,

we get,

9²- (b + c)²/{c² - (a - b)²}

= {81 - b² - c² - 2bc}/{c² - a² - b² + 2ab}

Therefore, the simplified expression is {81 - b² - c² - 2bc}/{c² - a² - b² + 2ab}

Answer:

poop=pee

Step-by-step explanation:

Alonzo rode the scooter for 44 minutes.

Let the fee to start the scooter be F, and let the cost per minute of the ride be C. We are given that Alonzo's total bill for the ride is T. With this knowledge, we can construct the following equation:

T = F + Cm

where m is the number of minutes Alonzo rode the scooter. We want to solve for m.

To find m, we may rewrite the equation as follows:

m = (T - F)/C

Therefore, the number of minutes Alonzo rode the scooter is (T - F)/C.

For example, let's say the fee to start the scooter is $2.50, and the cost per minute of the ride is $0.15. If Alonzo's total bill for the ride was $9.20, then we can plug these values into the equation above to find the number of minutes Alonzo rode the scooter:

m = (T - F)/C = (9.20 - 2.50)/0.15 = 44

Therefore, Alonzo rode the scooter for 44 minutes.

Answer:

3240°

Step-by-step explanation:

The sum of the interior angles of a polygon is found by (n-2)(180) where n is the number of sides so (20-2)(180) = (18)(180) = 3240°

A =  1/2 bh

Let's simplify the right side.

A = (bh) / 2

Multiply both sides by 2

2A = bh

Divide both sides by b

(2A) / b = h
