Answer:
1. 5 is a solution to the inequality
2. 8 is a solution to the inequality
3. q=20 is a possible solution to the inequality
4. t=28 is not a possible solution to the inequality
Step-by-step explanation:
1.
1+f<7
subtract 1 from both sides of the inequality;
f<7-1
f<6
The value of f should therefore be strictly less than 6. From the alternatives given only the number 5 meets this condition and is thus a solution to the inequality.
2.
g-3>4
add 3 to both sides of the inequality;
g>4+3
g>7
The value of g should therefore be strictly greater than 7. From the alternatives given only the number 8 meets this condition and is thus a solution to the inequality.
3.
q-2>16
add 2 to both sides of the inequality;
q>16+2
q>18
The value of q should therefore be strictly greater than 18. Consequently, q=20 is a solution to the inequality since;
20>18
4.
t-7<10
add 7 to both sides of the inequality;
t<10+7
t<17
The value of t should therefore be strictly less than 17. Consequently, t=28 is not a solution to the inequality since;
28 is not less than 17.
Length in units:
Use phytogoras theorem or measure it by a ruler if your using a graph paper
AB = 5.65 units
AC = 5.83 units
CB = 1.41 units
Perimeter =5.65 + 5.83 + 1.41 = 12.89 units
Area = 1/2 * 1.41 * 5.65 = 3.98units
It would be better if you've attached the figure its angle I should calculate. But I'll help you with some advice. You can find application in the internet that will calculate any angle by different ways. Just search your question, it will be first link
Answer:
b) 270 ≥ 40.18d + 3.75
Step-by-step explanation:
Per day is a variable, so it's 40.18d
Per mile is also a variable so 0.05m
40.18d + 0.05m ≤ 270
40.18d + 0.05(75) ≤ 270
40.18d + 3.75 ≤ 270
