Answer:
1. 42.8 °C
2. Aceves' class: $133.33; Baca's class: $266.67; Canyon's class: $200.
Step-by-step explanation:
1.) The difference between two numbers is found by subtraction. Since we want to report the positive difference, we can subtract the smaller number from the larger:
-21.2 °C - (-64 °C) = (64 -21.2) °C = 42.8 °C
The temperature must drop 42.8 °C more for the antifreeze to solidify.
_____
2.) We want to divide the prize money in the ratio
1200 : 2400 : 1800 = 2 : 4 : 3
There are 2+4+3 = 9 total ratio units, so each one must stand for $600/9 = $66 2/3.
Then the money to Aceves' class is ...
2 × $66 2/3 = $133 1/3 = $133.33
And the money to Baca's class is ...
4 × $66 2/3 = $266 2/3 = $266.67
Finally, the money to Canyon's class is ...
3 × $66 2/3 = $200.00
___
Note on the division:
The 1/3 cent that Aceves' class should have gotten goes to Baca's class in the above scenario. It might make sense for the classes to donate $6 to the school and divide the remaining $594 as $132 : $264 : $198. If they actually want the pennies, they could donate $0.06 to the school and split the result as $133.32 : $266.64 : $199.98.
Your answer is 10.
40-30=10

Answer: 35 more times
How: (if she gets 60 points for each grocery store visit then first do 2580-480=2100. she still needs 2100 points so then 2100/60 = 35 grocery visits!)
Firstly, we need to understand the formula of point-slope form:
Where x and y is the coordinates and m is the slope respectively.
To find the slope:
In this case:
We can then put the above slope and the point (-1,4) into the formula:
4-y = -1/2(-1-x)
-y = 1/2+1/2x-4
y = -1/2x+7/2
Alternatively:
y-4=-1/2(x-(-1))
y=-1/2x-1/2+4
y = -1/2x+7/2
Therefore the answer is y = -1/2x+7/2.
Hope it helps!
