There are 25 gold cards and 25 silver cards in - 1

Answers

Answer 1
Answer: A.  There are 25 gold cards, and 5 silver cards with a multiple of 10, so the probability is (25+5)/50=0.6.

B.  There are 25 silver cards and 4 gold cards with a multiple of 7 (7, 21, 35, and 49), so the probability is (25+4)/50=0.58.
Answer 2
Answer: Solutions

There are 25 gold cards and 25 silver cards in a deck. The gold cards are number 1,3,5,.....49 and the silver cards are numbered 2,4,6,.....50.  

A. The probability would be (25+5)/50=0.6.

B.we know that there are 25 silver cards and 4 gold cards with a multiple of 7, so the probability would be (25+4)/50=0.58.

Jalen gets 3 paid vacation days for every 60 days he works. Select all of the expressions that represent the number of vacation days gets per x days worked. (A) x/20 (B) 3/60x (C) x/3 (D) 0.05x (E) 20x

Answers

Answer:

A and D

Step-by-step explanation:

In this question, we are asked to select the expressions that represent the number of vacation days per x days worked.

Now, to do this, what we simply first do is to get the number of days to takes to get one paid vacation. In the question , we are made to know that he gets 3 days paid vacation for 60 days of work. The number of days to get a single paid vacation would thus be 60/3 = 20 days. This means she gets one paid vacation in 20 days.

Now, we are told after working for x days, how many paid days vacation does she get. To know this, what we do is to first know the number of 20 days in x days. That would simply be x/20. This is the number of vacation days she gets in x days.

now, we check if there are similar options to this.

D is also correct. This is because x/20 is same as 0.005x

Look at this equation k + 31 = 72 Which related equation below will correctly solve for the variable k? Question 1 options: k = 72 + 31 k = 72 - 31 k = 72 · 31 k = 72 ÷ 31

Answers

Answer:

To solve for the variable "k" in the equation "k + 31 = 72," you need to isolate "k" on one side of the equation. Here's how you can do it using friendly words and reasons:

1. Start with the original equation: "k + 31 = 72."

2. To isolate "k," you want to get rid of the "31" on the left side of the equation. You can do this by subtracting 31 from both sides to keep the equation balanced.

3. Subtract 31 from both sides:

"k + 31 - 31 = 72 - 31."

4. Simplify both sides:

"k = 41."

Step-by-step explanation:

So, the correct equation to solve for the variable "k" is: "k = 72 - 31," and this will give you the value of k, which is 41.

Tom's Tent Rental charges a flat rate of $100 per day plus $10 for each hour the tent is used. If the number of hours is represented by "h," which algebraic expression represents the overall rate for the day using "h"?100 + 10h

10h

100 + h

90h

Answers

100 + 10h

The 100 represents the $100 and the 10h represents the $10 times the hours 

Final answer:

The algebraic expression that represents the overall rate for a day's tent rental from Tom's Tent Rental, considering both the flat rate and the hourly charges, is '100 + 10h'.

Explanation:

To solve the problem, we need to express the situation in algebraic form. In this case, Tom's Tent Rental charges a flat rate of $100 per day, so we have '100'. Additionally, it costs $10 for each hour the tent is used. If we denote the number of hours as 'h', then the charge for the hours used would be '10h'.

Therefore, the total cost or the algebraic expression representing the overall rate for the day, considering both the flat rate and the hourly charges would be '100 + 10h'.
