(4,3) ? Im not sure. Hope it helps? :)
Answer: door hinges<$4.69
Step-by-step explanation: From the question, we can deduce that
1. Jonah has just $50 and can’t spend beyond it, so his total budget must be less than or equal to $50
2. Jonah will spend a total of $12.54 (add all the items with known prices),
leaving him with $37.46(50-12.54) to spend on 8 door hinges.
Therefore 8x<=37.46(8x has to be less than or equal to $37.46)
x=door hinges
Hence, x<=4.6825 (divide both sides by 8)
But we wouldn’t spend such fraction, lol, so we’ll approximate to the nearest cent.
x<4.69 ( I chose the higher number and removed the equal sign)
OR x<=4.68
Answer:
D
Step-by-step explanation:
If it is half the distance, it would be divided by 2. plus 5 miles more would be added after the division.
26 rounded to the nearest 10 is 30
Answer:
31 human cases.
Step-by-step explanation:
The least squares line equation for the number of reported dead birds (x), versus the number of human West Nile virus cases (y) is
y = -10.2638 + 0.0491x
If the number dead birds reported in a year is 844, then we have to find the numbers of human cases of West Nile virus.
To find the numbers we will plug in the value of x = 844 in the linear equation.
y = -10.2638 + 0.0491(844)
= -10.2638 + 41.4404
= 31.1766
≈ 31
Therefore, 31 human cases can be expected.
