3/4 w=6 solve for w
Bc.
Answers
To solve for w, you need to isolate the variable on one side of the equation.
The equation is 3/4 w = 6.
To isolate w, you need to divide both sides of the equation by 3/4.
3/4 w / 3/4 = 6 / 3/4
The left side simplifies to w, because the 3/4 on the left side cancel out.
w = 6 / 3/4
To divide by a fraction, you need to multiply by its reciprocal.
w = 6 * 4/3
The right side simplifies to 8.
w = 8
Therefore, w = 8.

Light travels from the sun at 1.12 x 107 miles per minute. The planet, Mars, is approximately 1.42 x 108 miles away from the sun.
What is the approximate amount of time, in minutes, for light to travel from the Sun to Mars? Write your answer in scientific notation rounded to the nearest hundredth.
Answers
Answer:
Time = 1.27 x 10^1 minutes
Step-by-step explanation:
To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.
Given:
Speed of light = 1.12 x 10^7 miles per minute
Distance between the Sun and Mars = 1.42 x 10^8 miles
Time = Distance / Speed
Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)
Time = (1.42 / 1.12) x 10^(8 - 7) minutes
Time = 1.27 x 10^1 minutes
Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.
Time = Distance / Speed
Given:
Speed of light = 1.12 x 10^7 miles per minute
Distance from the Sun to Mars = 1.42 x 10^8 miles
Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)
To simplify the calculation, we can divide the numerical values and subtract the exponents:
Time = 1.42 / 1.12 x 10^(8 - 7) minutes
Time = 1.27 x 10^1 minutes
Rounding to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.7 minutes in scientific notation.

Liz's age is two-thirds of Debbie's age. Debbie's age is half of Freya's age. what is the ratio of Liz's age to Freya's age?
Answers
Answer:
Let's start by using variables to represent the ages of the three people:
Let L be Liz's age.
Let D be Debbie's age.
Let F be Freya's age.
From the problem, we know that Liz's age is two-thirds of Debbie's age, so we can write:
L = (2/3)D
We also know that Debbie's age is half of Freya's age, so we can write:
D = (1/2)F
To find the ratio of Liz's age to Freya's age, we need to express Liz's age and Freya's age in terms of a common variable. Since we have an equation relating Debbie's age to Freya's age, we can use that as the common variable. From the equation D = (1/2)F, we can solve for F in terms of D:
F = 2D
Now we can substitute this expression for F into the equation for Liz's age:
L = (2/3)D = (2/3)(1/2)F = (1/3)F
So Liz's age is one-third of Freya's age. The ratio of Liz's age to Freya's age is therefore 1:3.

Answer:
D
Step-by-step explanation:
Using the rules of exponents
\(a^{m}\) × \(a^{n}\) = \(a^{(m+n)}\) and \(a^{-m}\) = \(\frac{1}{a^{m} }\)
Given
\(2^{-4}\) × 2² = \(2^{(-4+2)}\) = \(2^{-2}\) = c , hence
c = \(2^{-2}\) = \(\frac{1}{2^{2} }\) = \(\frac{1}{4}\) → D
Answer:
The answer is option D.
Step-by-step explanation:
2^-4 • 2² = a^b = c
Use the rules of indices
Since the bases are the same and they are multiplying we add the exponents
That's
2^-4 + 2 = a^b = c
2^-2 = a^b = c
a^b = 2^-2
c = 1/4

Dylan and Tiffany each constructed a two-color spinner. Dylan spun his spinner 3 times and calculated that the
relative frequency of his spinner landing on blue (0.67) and on red (0.33). Tiffany spun her spinner 200 times
and calculated the relative probability of her spinner landing on blue (0.60) and on red (0.40).
How can Dylan's and Tiffany's calculations be used to evaluate the fairness of the two spinners?
Answers
Answer:
You can calculate the likeliness of the spinner landing on blue or red as the more spins you have the more accurate the results would be. In this case after 200 spins Tiffany calculated that the spinner landing on blue has a 60% chance while landing on red has a 40% chance. Therefore this might not be fair as there is a 60% chance landing on blue.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

In a pile of playing cards, there are six hearts, twelve clubs, and six diamonds. What is the probability that you will draw a heart?
1/2
1/6
1/4
1/3
Answers
Answer:
Step-by-step explanation:
1/4 because all equal 24 together
and so
12 is half so pulling a club would be 1/2
6 is a fourth so pulling a diamond or heart would be 1/4
because 6x2=12 so pulling a diamond or heart would be 50 - 50 from pulling a heart/diamond or a club
6=cards
2=diamonds and hearts
The probability of drawing a heart from the pile of 52 cards is 0.25.
The ratio of the number of favorable outcomes to the total number of outcomes of an event is defined as probability.
We know, the probability of an event = Number of favorable outcomes/Total number of outcomes.
As it is given that there are 6 hearts, 12 clubs, and 6 diamonds in a pile of playing cards.
Therefore, the total number of outcomes = 6+12+6= 24
and number of favorable outcomes = 6
Now, the probability of an event = 6/24
= 1/4
= 0.25
Therefore, the probability of drawing a heart is 0.25.
