Answers

Answer 1

Answer:

I'd guess 54

Step-by-step explanation:

If the sections are all equal sized, there's an equal chance the arrow/spinner would land on them. If you divide 240 by 5, you get 48. The closest number to 48 is 54.

Answer 2
I think the answer is 54

Q6)

Kerry's workday is 10 hrs. and works 40 hrs. per week, Kerry works for 4 days

Watson's workday is 8 hrs. and works 40 hrs. per week, Watson works for 5 days

Kerry: works 4 days and gets paid $ 12.75 per cat & grooms 15 cats per day, so Kerry makes = 4(12.75 × 15) = 4(191.25) = $ 765

Watson: works 5 days and gets paid $ 12.75 per cat & grooms 10 cats per day, so Watson makes = 5(12.75 × 10) = 5(127.50) = $ 637.50

∴ The difference between their weekly earning is 765 - 637.50 = $ 127.50

Please help! There is 2 question! Thank you so much

Answers

Answer:

The answers are:

Question 23: 140

Question 24: 25

Step-by-step explanation:

Question 23:

Since 25% is 1/4 of the total amount of members in the club, we need to multiply the amount of drum player (35), by 4.

35 x 4 = 140

Question 24:

The absolute value of -25 is 25, since the absolute value is the value without any signs.

Therefore, the answers are:

Question 23: 140

Question 24: 25

Question 23 is 140 because since there is 25% that would be 1/4 and you would divide by 4.

Question 24 is 25 I think.

5+k/4=3 please explain thoroughly

Answers

To solve this equation, you must multiply by a denominator and then subtract to isolate a variable.

Remove the Denominator

Multiply by 4 on both sides of the equation.

[tex]\displaystyle 4(5 + \frac{k}{4}) = 4(3)[/tex]

[tex]\displaystyle 20 + k = 12[/tex]

Simplify

Subtract 20 from both sides to isolate the k.

[tex]20 - 20 + k = 12 - 20[/tex]

[tex]\boxed{k = -8}[/tex]

The final answer is k = -8.

Rachel bought 2.5 pounds of cookies for $13.40. Her friend buys 4.5 pounds of crackers for $24.75. Which is less
expensive per pound? By how much? (HINT: Find the unit rate for each, then find the difference)

Answers

Cookies: $13.40 divided by 2.5 = $5.36
Crackers: $24.75 divided by 4.5 = $5.50
Therefore, Cookies are less.
the answer would be the crackers are more expensive per pound and by $0.14. if you divide the price of the cookies by the amount of pounds you would come up with about $5.36 per pound. and if you do the same with the crackers it would be about $5.50 per pound.
