Quinn is a contestant on a quiz show. Quinn's score changes by -15 points for 4 questions in a row. ) What is the total change in Quinn's score?
The length and width of the rectangle is 362 m and 272 m respectively.
Step-by-step explanation:
Let the length be "x m".
then the width = x - 90 m
Perimeter = 2 x (length + width) ------------------------------(1)
Substituting Length and width value in the above equation (1), we get,
2 x (x+x-90) = 1268
or, 2x - 90 = 1268/2
or, 2x - 90 = 634
or, 2x = 634 + 90
or, 2x = 724
or, x = 724/2
= 362
Thus the length = 362 m
width = 362 - 90 m = 272 m
Answer: approximately 5.1818 pounds per square inch (psi)
========================================================
Work Shown:
P = pressure
T = temperature
The pressure is directly proportional to the temperature, which means P = k*T where k is some constant. As T goes up, P goes up as well, and vice versa. If P goes down, then T goes down too (or vice versa). In short, P and T go up together or go down together.
We're told that 6 psi (pounds per square inch) correspond to a temperature of 440 degrees F. This means P = 6 and T = 440 pair up. Let's use this P and T pairing to find k.
P = k*T
6 = k*440
6/440 = k
k = 6/440
k = 3/220
Therefore, the equation
P = k*T
updates to
P = (3/220)*T
--------------------
The last step is to plug in T = 380 to figure out the paired value of P
P = (3/220)*T
P = (3/220)*380
P = 5.1818 approximately
Answer:
0,5X + (-2), but you have to solve it... I give you the equation.
Step-by-step explanation:
In part A you have to find the equation of the line, so you do end - origin and you'll find m. I can only help you with the first one.
so:
(8,2) and (10,3)
(10-8,3-2) = (2,1)
V2/V1= 1/2= 0,5=m (slope of the line)
y= mx+n (change y, x and m with the ones above)
2= 8·0,5+n
2= 4+n
n= 2-4=-2
the equation is: 0,5X + (-2) and then you just have to change x in both equations, the second one is the h(x) adn it will give you the answer to A.
I hope I'm being helpful..!!!

x = 80°
Step-by-step explanation:
These are both isosceles triangles, so the top 2 angles are both 65°. The last angle of that triangle is 180° - (65° + 65°) which is 50°. Then, the opposite of that angle is in the next triangle. It is also 50°. So the 2 base angles are both 50°, so x is 180° - (50° + 50°) which is 80°.
