4(2a+3) = 8a+ 12 This represents the distribution property because it multiplies everything in the parentheses. 4 X 2a = 8a 4X3=12

You need a 65% alcohol solution. On hand, you have a 50 mL of a 30% alcohol mixture. You also have 70% alcohol mixture. How much

DIA [1.3K]

Answer:

350 mL

Step-by-step explanation:

Let q represent the quantity (in mL) needed of the 70% solution. Then the total amount of mixture will be q+50 milliliters. The total amount of alcohol in the mixture will be ...

0.70q +0.30(50) = 0.65(50 +q)

.05q = 17.5 . . . . . . subtract (0.65q +1.50)

q = 350 . . . . . . . . . divide by 0.05

You will need 350 mL of the 70% solution.

A certain circuit board consists of two resistors, green and red. The circuit board manufacturer has two huge bins filled with t

Lesechka [4]

Answer:

(a) 0.675

(b) 0.3

Step-by-step explanation:

$P(R) = 90\% = 0.9$ (Probability of functional red)

$P(\sim R) = 90\% = 1 - 0.9 = 0.1$ (Probability of non-functional red)

$P(G) = 75\% = 0.75$ (Probability of functional green)

$P(\sim G) = 1 - P(G) = 1 - 0.75 = 0.25$ (Probability of non-functional green)

(a) The probability the board is functional is the probability that the red and the green resistors are functional.

$P(\text{board is functional}) = P(R\cap G) = P(R) \times P(G) = 0.9\times0.75 = 0.675$

(b) The probability that exactly one of the resistors chosen is functional is the probability that either red is functional and green is not or green is functional and red is not.

$P(\text{exactly one is functional}) = P((R\cap \sim G) \cup (G\cap \sim R))$

$P(\text{exactly one is functional}) = P(R\cap \sim G) + P(G\cap \sim R) = (P(R) \times P(\sim G)) + (P(G) \times P(\sim R))$

$P(\text{exactly one is functional}) = (0.9 \times 0.25) + (0.75 \times 0.1) = 0.225 + 0.075 = 0.3$

After an earthquake 4/7 of all claims were paid within a month. Of all remaining claims I have not been paid yet 2/3 of them wer

koban [17]

Answer:

multiplication

Step-by-step explanation:

In math, "X of Y" means that X is multiplied by Y*. Here, you need to figure out what values are being multiplied.

The fraction of claims remaining unpaid after the first month is ...

1 - 4/7 = 7/7 -4/7 = 3/7 . . . . fraction of claims unpaid after month 1

The problem statement tells you 2/3 of these are paid in the second month. That is ...

(2/3) × (3/7) = 2/7 . . . . of the total of all claims

2/7 of all claims were paid in the second month.

_____

* The interpretation of the word "of" will depend on the context. Here, we're referring to X being a percentage or fraction, as in "2/3 of 3/7".

In some uses, the word "of" may signify that X is multiplied by a fraction with Y as the denominator, as in "5 of 8" (meaning 5/8), for example. If Y is an object, the X is still a multiplier, as in "3 of the bags of cement".
