Answer 1

Answer: 1. Answer: 15.7143

log (7x-10)=2

Use the identity: loga(x)=b = x=(a)(b)

7x-10=10^2

Evaluate the Power

7x-10=100

Addition Property of Equality

7x=110

Division Property of Equality

x=110/7 or 15.7143

2. Answer: 0.3107

log(3)+log(x^-3)=2
log(3x^-3)=2
log(3 x 1/x^3)=2
log(3/x^3)=2
3/x^3=10^2
3/x^3=100
3=100x^3
3/100=x^3
Answer Cube root 30 / 10 or 0.3107

3. Answer: 0.002

5x= 10^-2
5x=1/10^2
5x=1/100
x=1/500

Which statement about the graph is true? On a coordinate plane, a line goes through points (0, 2), (2, 3), (4, 4), (6, 5). The graph shows a proportional relationship because it is a line, and the difference between each point is the same. The graph shows a proportional relationship because it is a line, and each x-value is a multiple of 2. The graph does not show a proportional relationship because each point written as a ratio gives a different value. The graph does not show a proportional relationship because a line that increases by 1 in the y-value cannot have a constant of proportionality.

1.1. Kalvin always has cereal for breakfast. He likes Cocoa Blast cereal, but his mother wants him to eat Heath Nut Flakes at least some mornings.Kalvin and his mother agree to leave the cereal problem to chance. Each morning Kalvin tosses a coin. If the coin lands on heads, he will have Cocoa Blast. If the coin lands on tails, he will have Heath Nut Flakes. 1.2. Kalvin wants to find something else to toss that will give him a better chance of eating his favorite cereal each morning. He wonders if a paper cup would be a good thing to toss. Because Kalvin wants to eat Cocoa Blast more of the time, he needs to determine if the cup lands in one position more often than another. If so, he will ask to toss a paper cup instead of a coin. 1. Kalvin tosses a paper cup once a day for a year to determine his breakfast cereal. Use your results from problem 1.2 to determine the following. a. How many times do you expect the cup to land on its side? On one of its ends? b. How many times do you expect Kalvin to eat Cocoa Blast in a month? In a year? Explain. The cup lands on its side 80%(0.8) of the time, while it lands on its edges 20%(0.2) of the time, Heads on a coin would be equal to the cup landing on its side, and landing on its edges would be equal to a coin landing on tails.
Maria and Jeff collect data on the number of cars that pass through an intersection every Monday morning for 2 months. They record the findings as 78, 158, 63, 71, 56, 67, 75, and 64. They each use different methods to summarize the typical number of cars that pass through the intersection at the specified time and compare their findings. Jeff says that, on average, 79 cars pass through the intersection each Monday morning. Maria disagrees and says that the mean should not be used and uses the median instead to describe the typical number of cars that passes through the intersection on any given Monday morning.A) What is the median value of the data?

60x-3x to the second power divided by 3x

Answers

one way is to find ones or factors
example 4/2=2/2 times 2/1=1 times 2/1

then we undistribute the factor
we want a factor of 3x to make a one
60x=3x times 20
-3x^2=3x tiimes -x
use undistributive property which is
ab+ac=a(b+c)
so
60x-3x=3x(20)+3x(-x)=3x(20-x)
so now we have
[3x(20-x)]/3x=(3x/3x) times (20-x)/1=1 times 20-x=20-x

answer is 20-x

a music teacher has 4 drum kits. Each kit has 2 drumsticks. Each drumstick cost $3. How many drumsticks does she have? What is the cost to replace them all?

Answers

Answer: to replace all of the drumsticks it would cost $24

Step-by-step explanation:

Answer:

4 x 2 =8 * $3 =$24

She has 8 drumsticks since she has 4 drum kits and each kit has 2 drum sticks you would do 4 x 2 which equals 8.

Since there are 8 drum sticks and each drum stick costs 3$ you would do 8 x3 which would sum up to 24.

After 1 month, the book club had 5 members. The number of club members doubled every month.How many members did the club have after 4 months?

[ ]

Answers

Alright, take it step by step...in month one, they had 5 members.
if the number doubles each month, then the second month they will have a total of ten members, right? in the third they will have twice the number before, or 2 times 10, 20. if you double 20, you have the number of people in the fourth month, giving you a grand total of 40.

Since you know that the number of club members doubled every month , you would multiply how much members in one month by 2
1 month= 5 members multiply by 2
2 month= 10 members multiply by 2
3 month = 20 members multiply by 2
4 month= 40 members

So, for each moth you multiply it by 2.
After 4 months there will be 40 members

Final answer:

To subtract the given expressions, first, simplify each expression separately by combining like terms. Then subtract the second expression from the first expression by distributing a negative sign and adding it to the first expression.

Explanation:

To subtract the given expressions, (2x^3+7x^2-4) - (2x^2+4x-10), we need to simplify each expression separately and then subtract them. First, combine like terms within each expression. Then, subtract the terms of the second expression from the first expression. This can be done by distributing a negative sign to each term in the second expression and then adding it to the first expression.

So, (2x^3+7x^2-4) - (2x^2+4x-10) = 2x^3+7x^2-4 - 2x^2-4x+10.

Combining like terms, we get 2x^3+(7x^2-2x^2)+(-4-4x)+(10). Simplifying further, we have 2x^3 + 5x^2 - 4x + 6. Therefore, the result of the subtraction is 2x^3 + 5x^2 - 4x + 6.
