The mean amount of water in 5 containers is 620 ml the total amount of water in 4 q of the containers is 2750 what is the amount
EleoNora [17]
<span>The <u>correct answer</u> is:

350 ml.

Explanation<span>:

Let x be the amount in the fifth container.

The mean is found by adding all of the amounts together and dividing by the number of containers (in this problem, 5). We know that the total from the other 4 containers is 2750; add this to x, our unknown number. Then we divide by 5 to arrive at our answer of 620.

Algebraically,
</span></span>\frac{2750+x}{5}=620<span><span>

To solve, multiply both sides by 5:
</span></span>\frac{2750+x}{5}\times 5=620\times 5&#10;\\&#10;\\2750+x=3100<span><span>

Subtract 2750 from both sides:
 2750+x-2750=3100-2750
x=350.

There are 350 ml in the fifth container.</span></span>

The McCarter family is determining whether they want to buy a summer pass to the local swimming pool. Without a summer pass, the
Rus_ich [418]

Answer:

D. The McCarter's must make more than 10 visits to the pool for the pass to be a better deal.

Step-by-step explanation:

First, I chose the option that seemed most likely. Once I chose D, I plugged in the answer to see if it actually worked.

10 x 7.5 =75 dollars + 50 (pass fee) = 125 dollars total.

10 x 12.5= 125 dollars.

Therefore, in order to get a deal off of the seasonal pass, the McCarter's would have to visit the pool more than 10 times. D.

Sis In order to identify the zeros of the function, a student factored the cubic function ()=−−f of , open x close , equals , x
creativ13 [48]

Answer:

f(x)=x(x-5)(x+2)

Step-by-step explanation:

Since the steps of the factorization of the polynomial f(x) is not given, I will proceed to give the correct factorization of f(x).

f(x)=x³-3x²-10x

First, we factor out x since it is a common term.

f(x)=x(x²-3x-10)

Next, we factorize the quadratic expression x²-3x-10.

f(x)=x(x²-5x+2x-10)

f(x)=x(x(x-5)+2(x-5))

f(x)=x(x-5)(x+2)

The correct factorization of the polynomial f(x)=x³-3x²-10x is: f(x)=x(x-5)(x+2)

Use the quadratic formula to solve the equation if necessary round to the nearest hundredth x^2+x-30=0
yaroslaw [1]

Answer:

(x-5)(x+6)=0

Step-by-step explanation:

hehe i doing the smae unit rn.

if a=1 (which it does do ac factoring)

you need two numbers that multiply to -30 and add to 1. those numbers  are 5 and -6.

substitute 1x for -5x + 6x.

group the numbers into pairs and find their gcf's

x(x-5)    6(x-5)

since the parenthesis r the same yo only need one. Now you need to put x and 6 in a parenthesis.

FINAL: (x-5)(x+6) hope this helps
