Answer:
it takes about 2.79 seconds for the object to hit the ground
Step-by-step explanation:
t√h/4
h=125 feet
t=√125/4=√25×√5/4
t=5√5/4=11.18/4
t=2.79 secs
it takes the object 2.79 seconds to
hit theground

Answer: $609.88
Explanation:
Since Mary has two accidents in one year, we will use the note in the problem to compute for the new annual premium.
Using the note in the problem, we have the following steps:
- Subtract $32 from the original premium:
Result = $417.25 - $32 = $<span>385.25
- Then, get 150% of the resulting number in the previous step. First, convert 150% to decimal. So, 150% = 1.5
Result = </span>150% of $385.25 = 1.5 × $385.25 = $<span>577.875
- Finally to get the new premium, we add $32 to the resulting number in the previous step:
New Premium = </span>$577.875 + $32 = $<span>609.875
</span><span>
Since there is no half cents that exists today, we round-off the new premium to the nearest cent. Hence, the new premium is $</span><span>609.88.</span><span>

She did sell the newspapers for $.25 each at age 80. The equation is referred to as a linear equation in one variable if only one variable is present in the linear equation.
<h3>A linear equation is what?</h3>
It is described as the relationship between two variables, and a straight line results from plotting the graph of the linear equation.
The information provided in the issue is;
One newspaper will set you back $.25.
Other newspapers are $.40 each.
The 100 newspapers were purchased for $28.00.
x is the quantity of newspapers sold for $.25 each.
Y stands for the other newspaper's number.
The total of both newspapers is one hundred.
x+y=100
y=100-x
25x+ 40y=28.00
25x+40(100-x)=2800
25x+4000-40x=2800
-15x+4000=2800
-15x=-1200
x=80
She therefore sold 80 newspapers for $.25 each.

1. B forms a proportion, this is what I did, i simply 10/18 to 5/9 and i try to see if 5/9 is equivalent to 25/45 and it is. 5/9*5/5= 25/45
2. You multiply 27*4=108 then 108/12=9 so a=12
3. you multiply 16*21=336 then 336/12=28 so b=28
Hope this helps!
