What is this plz help
Aliun [14]

Answer:

x ≤ 3

Step-by-step explanation:

Given

2(4 + 2x) ≥ 5x + 5 ← distribute parenthesis on left side

8 + 4x ≥ 5x + 5 ( subtract 4x from both sides )

8 ≥ x + 5 ( subtract 5 from both sides )

3 ≥ x , then

x ≤ 3

If the mass of a material is 49 grams and the volume of the material is 7 cm^3, what would the density of the material be?
inysia [295]
The equation for density is:
density =  \frac{mass}{volume}

To help you remember - my teacher told us to remember "We <span>♡ density," and the heart stands for </span>\frac{m}{v}, or \frac{mass}{volume}. Cheesy, but it works!<span>
</span>
Back to the problem:
We know the mass if 49g and the volume is 7 cm^{3}, so plug these values into the equation for density:
density = \frac{mass}{volume}\\&#10;density = \frac{49\:g}{7\:cm^{3}} \\&#10;density = 7\:g/cm^{3}

Answer: The density is 7 g/cm^{3}

While mining Fred found a large metal bar that contained 24 ounces of nickel. Fred also determined that the bar was 80% nickel.
frutty [35]

Answer:

Not that I'm a chemistry expert but mathematically,The total weight of the bar is directly proportional to the known weight of the bar and the given percentage. I worked it out and found that the the total weight of the bar is 30 ounces. This is how I did it

Step-by-step explanation:

80:24

100:n

80(n)=100×24

A little equation and after it's solve the variable (n) will be equal to 30

The unit is added after calculations so that's how the answer is <em><u>3</u></em><em><u>0</u></em><em><u> </u></em><em><u>oun</u></em><em><u>ces</u></em>

PLEASE HELP GIVE BRANLIEST!!
Ipatiy [6.2K]

Answer:

1. 2/25

2. 4/15

Step-by-step explanation:

1. P(Y∩X)

Since  P(X) =2/3 , P(Y) =2/5 , and P(X|Y) =1/5, this is a conditional probability.

So  P(Y∩X) = P(Y)P(X|Y) = 2/5 × 1/5 = 2/25

2. P(Y)· P(X)

P(Y)· P(X) = 2/3 × 2/5 = 4/15
