Answer:
Julio's score change by (-230) or we can say Julio lost 230 points after his first three turns.
Step-by-step explanation:
We are given the following in the question:
Points lost after first turn = 95
Points lost after second turn = 55
Points lost after third turn = 80
We have to evaluate the change in Julio's score after his first three turns.
This could be done by adding three negative integers.
Here we use negative integers to represent Julio's point as these points were lost in the turn.
Change in Julio's score =
Thus, Julio's score change by (-230) or we can say Julio lost 230 points after his first three turns.
The expression 30t mean that the velocity of the football is 30, while the term 16t² makes the function to be quadratic.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given the equation:
f(t) = 6 + 30t – 16t²
Where f(t) is the height of the football after t seconds.
The constant 6 means the football was thrown from a height of 6 feet above the ground.
The expression 30t mean that the velocity of the football is 30, while the term 16t² makes the function to be quadratic.

Answer:
0.4 or 2/5
Step-by-step explanation:
Dana surveyed 20 students in total and out of those 20 only 8 got an A
so:
now if you simplify it 
and if you simplify it again:
or 0.4 in decimal
Answer:
Yes
Step-by-step explanation:
You can get there a couple of ways. One makes use of the secant rules that tell you ...
PQ × PR = PS × PT
Substituting for PR and PT, you have ...
PQ × (PQ + QR) = PS × (PS + ST)
PQ² + PQ×QR = PS² + PS×ST
Substituting PQ for PS everywhere, we have ...
PQ² + PQ×QR = PQ² + PQ×ST
Dividing by PQ gives ...
PQ + QR = PQ + ST
and subtracting PQ leads us to the conclusion ...
QR = ST
_____
Another way to look at it is to draw the chord QS. Then ΔQPS is an isosceles triangle, and the perpendicular bisector of QS bisects ∠P and also goes through the circle center. Then the figure is symmetrical about that diameter secant, making QR ≅ ST.
There are 2 footballs, and 8 baseballs
ratio of footballs: 2
Ratio of the total number of baseballs and footballs: add the two numbers together.
8 + 2 = 10
Note that footballs is first before the total amount.
2: 10 is your ratio.
Simplify the ratio. Divide 2 from both sides
2/2= 1
10/2 = 5
1:5 is your final ratio answer
hope this helps
