(6*5) + 2)
1 4/10 = 14/10
(1*10) + 4)
Step 2. If they don't have the same denominator, you have to find a common multiple (in this case, 10)
14/10 + 64/10
(14/10 × 1/1) + (32/5 × 2/2)

Richard is playing a game where he draws one playing card each out of two stacks of four cards.
Is Richard more likely to draw two cards with a product that is an even number or two cards with a product that is a single digit?
A. Richard is equally likely to draw two cards with a product that is an even number, or a product that is a single number, because .
B. Richard is more likely to draw two cards with a product that is a single digit, because .
C. Richard is more likely to draw two cards with a product that is an even number, because .
D. Richard is more likely to draw two cards with a product that is a single digit,because .
Answers
B. Richard is more likely to draw two cards with a product that is a single digit because there are more single-digit numbers than even numbers.
Is Richard more likely to draw two cards with a product that is an even number or two cards with a product that is a single digit?To determine which outcome is more likely, we need to analyze the number of possible outcomes for each case.
For two cards to have a product that is an even number, we need at least one of the cards to be an even number. In a standard deck of playing cards, there are 26 even-numbered cards (2, 4, 6, 8, 10) and 22 odd-numbered cards (Ace, 3, 5, 7, 9).
Therefore, the number of possible outcomes for two cards with an even product is 26 multiplied by 52 (the total number of cards in two stacks) minus the 26 cases where both cards are odd.
On the other hand, for two cards to have a product that is a single digit, the possibilities are limited to the numbers 1, 2, 3, 4, 5, 6, 7, 8, and 9. In a deck of playing cards, only the Ace, 2, 3, 4, and 5 cards satisfy this condition.
Therefore, the number of possible outcomes for two cards with a single-digit product is 5 multiplied by 52 minus the 5 cases where both cards are not within the single-digit range.
By comparing the number of possible outcomes, we can see that the number of outcomes for two cards with a single-digit product is greater than the number of outcomes for two cards with an even product. Thus, Richard is more likely to draw two cards with a product that is a single digit.

(C): Richard is more likely to draw two cards with a product that is an even number, because...
To determine the probabilities, let's consider the possible outcomes for each case:
Two cards with a product that is an even number:
To get an even product, at least one of the cards drawn must be even. There are three even cards in each stack (2, 4, and 6) and one odd card (3). The possible combinations are:
Even card × Even card
Even card × Odd card
Odd card × Even card
The probability of drawing an even card from the first stack is 3/4, and from the second stack is also 3/4. Since these events are independent, we multiply the probabilities:
P(Even card) = (3/4) × (3/4) = 9/16
Two cards with a product that is a single digit:
To get a product that is a single digit, both cards drawn must be either 1 or 2. There are two 1s and two 2s in each stack. The possible combinations are:
1 × 1
1 × 2
2 × 1
2 × 2
The probability of drawing a 1 from the first stack is 2/4, and from the second stack is also 2/4. Again, since these events are independent, we multiply the probabilities:
P(Single digit) = (2/4) × (2/4) = 4/16
Comparing the probabilities:
P(Even card) = 9/16
P(Single digit) = 4/16
Since 9/16 is greater than 4/16, Richard is more likely to draw two cards with a product that is an even number. Therefore, the correct answer is C: Richard is more likely to draw two cards with a product that is an even number.

The temperature of a heat-producing chemical reaction is directly proportional to the square of the time elapsed. The reaction started at 0 degrees and reached 64 degrees in 5 minutes. Estimate the time taken by the reaction to reach 36 degrees.
A. 1.06
B. 2
C. 3.75
D. 4
Answers
The time taken by the reaction to reach 36 degrees will be 3.75 minutes. Then the correct option is C.
What are ratio and proportion?A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
The temperature of an intensity delivering synthetic response is straightforwardly relative to the square of the time slipped by. The response began at 0 degrees and arrived at 64 degrees in a short time.
The proportionality is given as,
T ∝ t²
T = kt²
Where T is the temperature, t is the time, and k is the constant of proportionality.
The time taken by the reaction to reach 36 degrees will be given as,
36 / 64 = t² / 5²
0.5625 = t² / 25
t² = 14.0625
t = 3.75 minutes
The time taken by the response to arrive at 36 degrees will be 3.75 minutes. Then the right choice is C.

3. A drawer contains a dozen brown socks and a dozen black socks, all unmatched. A man takes socks out at random in the dark. a) How many socks must he take out to be sure that he has at least two socks of the same color
Answers
The number of socks that must he take out to be sure that he has at least two socks of the same color is 3.
ProbabilityIn a situation were three (3) socks are taken from the drawer, at least two (2) socks must have the same color.
Using this formula
P=P(Red)+P(Black)+P(Either red or black)
Where:
P(Red)=1
P(Black)=1
P(Either red or black)=1
Hence:
P=1+1+1
P=3 socks
Therefore the number of socks that must he take out to be sure that he has at least two socks of the same color is 3.

x^2 - 2x - 14 = 0
Answers
To complete the square for the equation x^2 - 2x - 14 = 0, follow these steps:
1. Move the constant term to the right side of the equation: x^2 - 2x = 14
2. Take half of the coefficient of x, square it, and add it to both sides of the equation: x^2 - 2x + 1 = 15
3. Factor the left side of the equation as a perfect square: (x - 1)^2 = 15
4. Take the square root of both sides of the equation, remembering to include both the positive and negative square roots: x - 1 = ±√15
5. Add 1 to both sides of the equation to isolate x: x = 1 ± √15
Therefore, the solutions to the equation x^2 - 2x - 14 = 0 are x = 1 + √15 and x = 1 - √15.

Answers
The length of the minor arc AB is approximately 16.8 cm (to 1 decimal place).
To find the length of the minor arc AB, we need to calculate the circumference of the entire circle and then find the fraction of the circumference represented by the central angle OAB.
The formula for the circumference of a circle is given by C = πd, where C is the circumference and d is the diameter.
Given that the diameter of the circle is 68 cm, we can calculate the circumference:
C = πd
C = π(68 cm)
C ≈ 213.628 cm
Now, to find the length of the minor arc AB, we need to find the fraction of the circumference represented by the central angle OAB. Since the central angle is given in degrees, we can use the formula:
Length of minor arc AB = (Central angle/360°) * Circumference
Length of minor arc AB = (28°/360°) * 213.628 cm
Length of minor arc AB ≈ 16.776 cm

A computer originally priced at $850 is on sale for 15% off. What is the sale price of the computer?

Sale price: $722.50
Step-by-step explanation:
Subtract 15% from 100%, obtaining 85%. The computer is sold for 85% off.
Converting this 85% to a mixed decimal, we get 0.85, and then we multiply the original price ($850) by this 0.85: 0.85($850) = $722.50
