The expression that represents the number of days until only 10% remains is
T((d) 10%) = 100 • (1/2)^3.322
Given:
pool length : 10 yards
pool width : 8 yards
Area = 10 yds * 8 yds = 80 yd²
(10 + 2x)(8 + 2x) = 120
10(8 + 2x) + 2x(8+2x) = 120
80 + 20x + 16x + 4x² = 120
4x² + 36x + 80 - 120 = 0
4x² + 36x - 40 = 0
4(x² + 9x - 10) = 0
4(x + 10)(x - 1) = 0
x + 10 = 0
x = -10
x - 1 = 0
x = 1
the width of the deck is 1 yard
Answer:
(-4,5)
*View attached graph*
Step-by-step explanation:
y = -2x - 3
4y + x = 16
4y + x = 16
4(-2x - 3) + x = 16
-8x - 12 + x = 16
-7x - 12 = 16
+12 + 12
-7x = 28
/-7 /-7
x = -4
4y + x = 16
4y + (-4) = 16
4y - 4 = 16
+ 4 + 4
4y = 20
/4 /4
y = 5
(x,y) -> (-4,5)
Hope this helps!
Answer:
∠ DFE = 15°
Step-by-step explanation:
The inscribed angle DFE is half the measure of its intercepted arc, that is
∠ DFE = 
DE = × 30° = 15°
The mean GPA is greater than 2.75.

What is GPA?</h3>
- A grade point average is a figure that represents the average of the final grades obtained in courses over time.
- A student's grade point average, sometimes known as a GPA, is computed by adding all accumulated final grades and dividing the total by the number of grades granted.
To find the GPA:
- GPA is calculated and could be utilized by the college to tell choices, which include the subsequent educational progression.
- Divide the total range of grade factors earned with the aid of the total number of letter-graded units undertaken.
- Mean GPA = total/50
- = 2.75.
Therefore, the mean GPA is greater than 2.75.
