A lake near the Arctic Circle is covered by a 2-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 weeks, the sheet is only 1.25, point, 25 meters thick.
Let y represent the ice sheet's thickness (in meters) after x weeks.

Area of the square:
a^2: 4^2=16in^2
Area of the circle:
πr^2: π(4.5)^2= 63.6
Area of white part:
63.6 - 16 = 47.6
Probability of landing on square:
16/63.6 = 0.25
Probability of landing on white part:
63.6/16 = 3.975

Answer:
f(x)=-2x^2+32x-114
Step-by-step explanation:
Answer:
f(x) = -2x^2 + 142
Step-by-step explanation:
f(x) = -2(x - 8)^2 + 14
f(x) = -2(x)^2 - (-2)(-8)^2 + 14
f(x) = -2x^2 - (-2)(64) + 14
f(x) = -2x^2 - (-128) + 14
f(x) = -2x^2 + 128 + 14
f(x) = -2x^2 + 142

{45x+6y=15-x+18y=11 is..........................
Answer:
Step-by-step explanation:
45x+6y=15
-x+18y = 11
let's use elimination, the other way is by substitution, either way works but, it looks to me like elimination would be easy with the 'y'
3(45x+6y=15)
135x + 18y = 45 ( subtract 2nd eq. from 1st )
-( -x+18y = 11 )
136x +0y =34
x = 34 /136
x = 1 /4
there is X
plug that back into either of the 1st or 2nd equations to solve for y
- 1/4 + 18 y = 11
18y = 11 1/4
18y = 45/4
y = 45/4 * 1/18
y = 45/ 72
the fractions seem "difficult" but that's just what the given problem finds

PLZ answer this question y-5 ≥ -15
Answer:
y (is less than or equal to) 3
Step-by-step explanation:
i hope this helps :)
The value of the inequality will be : y ≥ -10 .
Given ,
y-5 ≥ -15
Here,
y-5 ≥ -15
To solve the given inequality,
Take -5 from LHS to RHS of inequality,
y ≥ -15 + 5
y≥ -10
Thus the value of y will be equal to or greater than -10 .

Answer: 16p^8q^4r^8 The yellow one
Step-by-step explanation:
Step 1: Use Multiplication Distributive Property: (xy)^a = x^a y^a. So 4^2p^2(q^3)(r^4)^2
Step 2: Simplify 4^2 to 16. So 16p^2(q^3)^2(r^4)^2
Step 3: Use Power Rule: (x^a)^b=x^ab. So 16p^2q^6(r^4)^2
Step 4: Use Power Rule: (x^a)^b=x^ab. So the answer is 16p^2q^6r^8. The yellow one

Example 2:
Step-by-step explanation:
The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} . Note that the domain elements 1 and 2 are associated with more than one range elements, so this is not a function.

8. In AABC, mC = 90° and sin A =
What is m angle B in degrees?
A. 30°
B. 45°
C. 60°
D. There is not enough information to determine.
Answer:
C
Step-by-step explanation:
The degrees of a triangle add up to 180.
Angle C is already 90 degrees therefore angle A + angle B = 90 degrees.
Angle A is equal to sinA=1/2.
sinA=1/2 is equal to 30 degrees if you press 2nd, sin (1/2) into the calculator. You may also know this if you have memorized the values of trig.
90-30=60.
That leaves you with 60 degrees for angle B.
