Step-by-step explanation:
We have
87+86+x
T is the total scores
n is number of tests done = 3
T/n is greater than or equal to 90
To get minimum test
T/n = 90
T = 90*n
= 90n
We solve for x
Remember n = 3
90x3 = 270
270 = 87+86+x
270 = 173+x
X = 270-173
X = 97
1.
X = 97
2.
You didn't add a value in your part b question. I used 80 though.
T/n < 80
T<80n
80x3= 240
T<240
87+86+x<240
X<240-173
X<67
X has to be less than 67 so we conclude that if x <=67 b grade will be lost.
The <em><u>correct answer</u></em> is:
h(t) = –16t² + 50t + 3
Explanation:
The general form of an equation such as this is h(t) = at² + v₀t + h₀, where a is the constant due to gravity, v₀ is the initial velocity and h₀ is the initial height.
We are given that the constant due to gravity is -16.
The initial velocity is 50, and the initial height is 3; this gives us the equation
h(t) = -16t² + 50t + 3
<span>Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. i hope this helps you</span>
Answer:
$131.25
Step-by-step explanation:
Take the $175 price and divide it by 0.25, which is the decimal version of 25%. You should get 43.25 which is 25% of 175. Then subtract 43.25 from 175 to get the final answer of $131.25 for the CD player if Martin buys it on Wednesday.
Answer: 13 comic books
Step-by-step explanation:
1st add 18 + 8 which equals 26
2nd subtract 130 - 26 which equals 104
3rd divide 104 / 8 because each comic book was $8
4th your answer is 13 comic books
