Answer:
A. The situation is discrete B. i. { x : 0 ≤ x ≤ 6; x ∈ Z} ii. { C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Step-by-step explanation:
A. The situation is discrete since we have integral values for the amount paid per mile walked. The amount per mile is $5 and is only paid if a complete mile is walked. So, it is a discrete situation.
B. i. Since 0 miles represents 0 distance and the student walks a maximum of 6 miles, let x represent the distance walked. So the domain is 0 ≤ x ≤ 6 where x ∈ Z where Z represent integers.
{ x : 0 ≤ x ≤ 6; x ∈ Z}
ii. Since at 0 miles the amount earned is 0 miles × $5 per mile = $ 0 and at the maximum distance of 6 miles, the amount earned is 6 miles × $5 per mile = $ 30, let C represent the amount donated in dollars. So the range is 0 ≤ C ≤ $ 30 where C = 5x.
{ C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Price of 3 shirts=$18*3=$54
Price of 2 pair of socks=2*$3.99=$7.98
Price of a pair of slack=$45
Total amount- $54+$7.98+ $45-$106.98
Sales tax rate = 8.5%
8.5% of total amount-8.5% of $106.98=
(8.5/100)*106.98-9.0933
Total amount Rick paid=$106.98+9.0933=$116.0733

Answer:
<u>Yes this is a Triangle</u>
36 degrees of any side then 41 would connct to 36 and 17 would connects to 36 and 41! If this is Khan Academy your asking out of its a Yes, it is a Triangle

7.5y - z/9 + 50 + 2y
Okay, so it would be best to organize and simplify this expression: 9.5y -z/9 + 50
Alright, now let's eliminate some answers.
True or false: The constant is 7.5. This is <em>false. </em>7.5 is a coefficient, 50 is a constant.
True or false: The coefficients are 7.5 and -9. This is <em>false. </em>Sure, 7.5 is a coefficient, but -9 is not. Actually, z/9 is also equal to (1/9)z, so <em>technically </em>1/9 is the coefficient.
True or false: The variables are x and y. This is <em>false. </em>Where is x? Nonexistent.
True or false: The like terms are 7.5y and 2y. This is <em>true. </em>When we simplified the equation, we first combined like terms. 7.5y and 2y are like terms and therefore able to be combined. That's how we got 9.5y.
The answer, I believe, is D. Hope this helps!
Answer:
17 packs
Step-by-step explanation:
If each pack of construction paper has 495 pieces
Mrs Perkins would like to get at least 8000 pieces of construction paper
Number of Packs She will need
= Total Pieces Needed/Number of Pieces per pack
=8000/495
=
Now, 16 X 495 =7920 and this is less than the required numbers.
Therefore, She will need at least 17 packs in order to have a minimum of 8000 pieces pf construction paper
