Customers at an ice cream shop took a survey. The results showed that 144 customers rated the shop as being "very satisfactory."

stepladder [879]

Answer:

320 customers is the answer

Step-by-step explanation:

1. You have to divide 144 by 45% to find one percent of the customers (you get 3.2).

2. Once you get one percent of all of the customers (3.2) you multiply it by 100 to get 100 percent of the customers (or total number of customers).

So, 320 total customers

Have a great day, I hope you like the explination.

What binomial do you have to add to the polynomial:

marshall27 [118]

Answer:

a) $-2x^2+5xy$

b) $-3y^2+5xy$

Step-by-step explanation:

Given polynomial : $2x^2+3y^2-5xy+1$

The binomial that should be added to the given polynomial to get a polynomial that does not contain the variable x is:

$-2x^2+5xy$

$(2x^2+3y^2-5xy+1)+(-2x^2+5xy)$

$=2x^2+3y^2-5xy+1-2x^2+5xy$

$=2x^2-2x^2+3y^2-5xy+5xy+1$

$=3y^2+1$

Given polynomial : $2x^2+3y^2-5xy+1$

The binomial that should be added to the given polynomial to get a polynomial that does not contain the variable y is:

$-3y^2+5xy$

$(2x^2+3y^2-5xy+1)+(-3y^2+5xy)$

$=2x^2+3y^2-5xy+1-3y^2+5xy$

$=2x^2+3y^2-3y^2-5xy+5xy+1$

$=2x^2+1$

If m(x) = x2 + 3 and n(x) = 5x + 9, which expression is equivalent to (mn)(x)?

Ilia_Sergeevich [38]

For this case we have the following functions:
$m (x) = x ^ 2 + 3

n (x) = 5x + 9$
Multiplying both functions, we obtain an expression equivalent to (mn) (x).
We have then:
$(mn) (x) = m (x) n (x)
$
Substituting values we have:
$(mn) (x) = (x ^ 2 + 3) (5x + 9)
$
Rewriting the expression we have:
$(mn) (x) = (5x ^ 3 + 15x) + (9x ^ 2 + 27)

(mn) (x) = 5x ^ 3 + 9x ^ 2 + 15x + 27$
Answer:
An expression that is equivalent to (mn) (x) is:
$(mn) (x) = 5x ^ 3 + 9x ^ 2 + 15x + 27$

Mary has 23 marbles 7/23 of the marbles are yellow and 13/23 of the marbles are blue the rest of the marbles are green how many

deff fn [24]

Answer:

The answer here is 3.

Step-by-step explanation:

Since 7 of the marbles are yellow and 13 of them are green, you would first add these numbers together to find the number of marbles that are not green. After doing this you will find that 20 of the marbles aren't green. Since there are 23 marbles, and 20 of them aren't green, you would subtract these two numbers to find that the number of green marbles is three.
