Answers

Answer 1

Answer: 3h + 2p = 192 -->(-2) 2h + 3p = 213 -->(3) ------------- -6h - 4p = - 384 (result of multiplying by -2) 6h + 9p = 639 (result of multiplying by 3) --------------add 5p = 255 p = 255/5 p = 51 now sub 51 in for p in either of the original equations to find h 3h + 2p = 192 3h + 2(51) = 192 3h + 102 = 192 3h = 192 - 102 3h = 90 h = 90/3 h = 30 check... 3h + 2p = 192 2h + 3p = 213 3(30) + 2(51) = 192 2(30) + 3(51) = 213 90 + 102 = 192 60 + 153 = 213 192 = 192 (correct) 213 = 213 (correct) 1 hr of horseback riding (h) costs $ 30 1 hr of para-sailing (p) costs $ 51

Answer 2

Answer: The first part of the math question is 64.3 and I think for the second part of the question as far as going parasailing is 71

Mrs. Rowan allotted 30 minutes at the beginning of class for her students to complete an exam. The last student took 42 minutes to complete the exam. What is Mrs. Rowan's percent error?

Answers

Using percentage concepts, it is found that Mrs. Rowan percent error is of 40%.

The percent error is given by the extra time afforded multiplied by 100% and divided by the allotted time.

In this problem:

Allotted time of 30 minutes.
The last student took 42 minutes to complete the exam, thus the extra time afforded was of 12 minutes.

The percent error is:

$P = (12)/(30) * 100\% = 0.4 * 100\% = 40\%$

The percent error is of 40%.

A similar problem is given at brainly.com/question/16903296

Step-by-step explanation:

Percent error = |actual − theoretical| / actual × 100%

|42 − 30| / 42 × 100% = 28.6%

Eduardo is building a sandbox that has an area of 84 square feet. What are the possible whole number measurements for the length and width of the sandbox?

Answers

To find the area, of a rectangle, you multiply length by width. Therefore, any factor pairs of 84 would be possible measurements for the length and width of the sandbox.
length=1ft, width=84ft (1x84=84)
length=2ft; width=42ft (2x42=84)
length=3ft; width=28ft (3x28=84)
length=4ft; width=21ft (4x21=84)
length=6ft; width=14ft (6x14=84)
length=7ft; width=12ft (7x12=84)
And switching the numbers around gives you more possibilities.
length=12ft; width=7ft
length=14ft; width=6ft
length=21ft; width=4ft
length=28ft; width=3ft
length=42ft; width=2ft
length=84ft; width=1ft
12 total possible whole number pairs for the length and width of the sandbox.
See how that works? Easy as pie, so long as you have the patience to find all the factors.
I hope this helps!

Look at this check register. Calculate the current balance. The current balance is $

Answers

Answer:

The current balance is $33.18.

Step-by-step explanation:

The initial balance is $82.92.

The debt are subtracted from the balance and deposits are add in the balance.

On 5/1 after paying the monthly fee the balance was $82.92.

On 5/3 phone bill of $78.24 is paid, so the remaining balance is,

$B=82.92-78.24=\$ 4.68$

On 5/15 the paycheck of $125.00 is deposited, so the remaining balance is,

$B=4.68+125=\$ 129.68$

On 5/17 withdraw from ATM of $40, so the remaining balance is,

$B=129.68-40=\$ 89.68$

On 5/20 tennis lessons of $56.50 is paid, so the remaining balance is,

$B=89.68-56.50=\$ 33.18$

Therefore, the current balance is $33.18.

Answer:

The current balance is $$ 33.18
