What is the result of isolating x^2 in the equation below?10x^2-36y^2=100

A. x^2=100+36/10 y^2
B. x^2=10+36/10 y^2
C. x^2=100+36 y^2
D. x^2=10+6/10 y^2

Answers

The result of isolating x² in the quadratic equation 10x² - 36y² = 100 will be x² = 10 + (36 / 10)y²

What is a quadratic equation?

A quadratic equation is an equation that has one or multiple variables with the highest power of the variable is 2.

The given quadratic equation is:

10x² - 36y² = 100

⇒ 10x² = 100 + 36y²

⇒ x² = (100 + 36y²) / 10

⇒ x² = 10 + (36 / 10)y²

B. you add 36y^2 to either side, giving you 10x^2=100+36y^2, and then divide the entire equation by 10, leaving you with x^2=10+36/10 y^2

What is the probability of choosing a card that does not have a digit 1 on it? Give the answer as a fraction numbers: 1,2,3,4,5,6,7,8,9,10

Answers

Final answer:

The probability of selecting a number, from the set {1,2,3,4,5,6,7,8,9,10}, that does not have the digit '1' on it, is 9 out of 10, or 9/10. Each selection is an independent event.

Explanation:

The subject of this question is Probability, a branch of Mathematics. Given the numbers 1,2,3,4,5,6,7,8,9,10, we have ten numbers in total, and only one of these numbers (1) is what we're trying to avoid. Hence, the probability of choosing a number that does not have the digit 1 on it is 9 (total numbers) - 1 (digit 1) divided by 10 total numbers, giving us a final answer of 9/10.

Probability can be represented as a fraction, where the numerator represents the favorable outcomes and the denominator represents the total number of outcomes.

Choosing each individual number is an independent event, meaning the outcome of each selection does not affect the probability of the subsequent selection.

what is the total pay for 12 hours of work at a base rate of p per hour plus a temporary raise of $2.50 per hour?

Answers

Answer:

$ 12(p+2.5)

Step-by-step explanation:

Given: base rate of pay is p per hours plus a temporary raise of $2.50 per hour.

To Find: total pay for 12 hours of work

Solution:

Total hours for which work is done = $\$$ $12$ $\text{hours}$

base rate of payment = $\text{p}$ per $\text{hours}$

temporary raise = $\$$ $\text{2.50 per hour}$

Total rate of payment = $\$ (p+2.5)$

Total pay = $\text{total time work done}*\text{total pay rate}$

putting values

= $\$$ $12(\text{p+2.5})$

therefore,

Total pay for 12 hours of work is $\$$ $12(\text{p+2.5})$

12(p+2.5)

Since he makes p + 2.5 per hour, and he is working for 12 hours, the above is how you would express it as a formula.

The graphic shows the schedule network diagram (in minutes) for assembling a toy train set. What is the duration of the critical path?A) 38 minutes
B) 41 minutes
C) 49 minutes
D) 51 minutes

Answers

D because it is longer than the rest

Final answer:

The critical path in a project schedule is the longest sequence of tasks from start to finish and determines the minimum total duration for the project. Without the diagram, the correct duration from your multiple-choice options cannot be determined accurately. The correct answer represents the duration of the longest path from the given options.

Explanation:

Without the graphic showing the schedule networkdiagram for assembling a toy train set, providing an accurate answer would be difficult. Normally, in project management, a Critical Path represents the longest sequence of tasks (or activities) in a project schedule from start to finish. It determines the minimum total duration required to complete the project. You identify the critical path by adding the times for the activities in each sequence and determining the longest path in the project.

In this case, assuming that you have the diagram in front of you and you've calculated the total duration for all paths, one of the multiple choice options (A) 38 minutes, (B) 41 minutes, (C) 49 minutes, or (D) 51 minutes would represent the duration of the critical path in the network diagram.

CupCaking, a cupcake bakery, uses the equation below to determine the price of cupcakes, where y represents the total price in dollars and x represents the number of cupcakes purchased.Y=3/2x

Cake Me, another cupcake bakery, uses the table below to determine prices.
(x) (y)
2 3.50
3 5.25
4 7.00
6 10.50

Katie bought one cupcake from CupCaking and Sarah bought one cupcake from Cake Me.

Which of the following are true?
A) Katie is paying the smaller price of $1.50 per cupcake.
B)Sarah is paying the smaller price of $1.25 per cupcake.
C) Katie is paying $0.25 per cupcake more than Sarah.
D)Sarah is paying $0.25 per cupcake more than Katie.
E)They are paying the same price per cupcake.

You can pick more then one :)

Answers

A is true and D is true because 3 divided by 2 is 1.5 and x is 1 ( the number of cupcakes she is buying) so the total she is paying for is 1.50 while if you notice the pattern in cake me they are charging 1.75 per cupcake. (7.00 - 1.75 = 5.25)

Answer:

Katie is paying the smaller price of $1.50 per cupcake.

Sarah is paying $0.25 per cupcake more than Katie.
