Answer:

78 sqr units

Step-by-step explanation:

Use the Pythagorean Theorem to help find the base opposite the two.

The base of the second parallel line is sqrt( (15^2) - (12^2) ) = sqrt(81) = 9

The second base = 9 + 2 = 11

Area = (b1 + b2)*h/2

h = 12

b1 = 2

b2 = 11

h = 12

Area = (11 + 2)*12/2

Area = 13 * 12/2

Area = 78 square units

If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40 how much would it cost to provide coffee for the whole

N76 [4]

Answer:

It would cost 15600 to provide coffee for the whole year.

Step-by-step explanation:

Given:

If 100 people drink 1.5 cups of coffee a day and the cost per cup is .40

Now, to find the cost to provide coffee for the whole year if you're place is open 5 days a week.

So, we have the unit rate, and we have to find the cost of 1.5 cup by multiplying 0.40.

1.5 cup of coffee cost $1.5\times 0.40=0.60.$

Thus, 1.5 cup cost 0.60.

If, 100 people drink 1.5 cups.

Then, total cost of 100 people drinking 1.5 cups of coffee = $100\times 0.60=60$

As, place is open 5 days a week.

So, to get the cost of coffee in 5 days of a week we multiply 5 by 60:

$5\times 60\\\\=300.$

Hence, the cost of coffee in a week is 300.

In 1 year there are 52 weeks.

Now, to get the cost for the whole year we multiply 52 by 300:

$52\times 300\\\\=15600.$

Therefore, it would cost 15600 to provide coffee for the whole year.

I am looking to decrease my bill by 25%. Can you look at my current plan and tell me what I can remove to achieve this reduction

Gennadij [26K]

Answer: $35

Step-by-step explanation:

From the question, we are informed that the current bill of the person is $140.00 per month and that the person wants to decrease the bill by 25%.

To know the amount that the person needs to deduct, we have to calculate 25% of $140.00. This will be:

= 25% of $140

= 25/100 × $140

= 1/4 × $140

= 0.25 × $140

= $35

The person will need to remove $35. The person will now pay ($140 - $35) = $105 monthly.

10 increased by the quotient of a number and 6 is 15

Makovka662 [10]

<h2>Verbal Phrase to Mathematical Phrase</h2><h3>Answer:</h3>

$10 +\frac{n}{6} = 15\\$

<h3>Step-by-step explanation:</h3>

Let that number be $n$ .

The quotient of a number and $6$ is $\frac{n}{6}\\$ .

"Increased" is just another term for "plus (+)" so $10$ increased by The quotient of a number and $6$ is $10 + \frac{n}{6}\\$

And it tells us that it is $15$ so it must be $10 +\frac{n}{6} = 15\\$

Multiply the polynomials (x+4)(x^2-5x+3)

tatiyna

(4x2 – 4x – 7)(x + 3)
 = (4x2 – 4x – 7)(x) + (4x2 – 4x – 7)(3)
 = 4x2(x) – 4x(x) – 7(x) + 4x2(3) – 4x(3) – 7(3)
 = 4x3 – 4x2 – 7x + 12x2 – 12x – 21
 = 4x3 – 4x2 + 12x2 – 7x – 12x – 21
 = 4x3 + 8x2 – 19x – 21
