Answer:
The population in 14 weeks is 232 fishes
Step-by-step explanation:
The equation for exponential growth is f(x) = a·(1 + r)ˣ
Where;
a = The starting population size = 3
r = The rate at which the population of grows
x = The number of periods to of change of the population
Therefore, we have;
f(6) = 31 = 3 × (1 + r)⁶
31/3 = (1 + r)⁶
㏑(31/3) = 6㏑(1 + r)
(㏑(31/3))/6 =㏑(1 + r)
1 + r = e^((㏑(31/3))/6) ≈ 1.476
1 + r ≈ 1.476
Therefore, the population in 14 weeks is given as follows;
f(14) = 3 × (1.467)¹⁴ ≈ 232.574
Given that we the information is with regard of living things, such that there are no fractions, we round down to the nearest whole number as follows;
f(14) ≈ 232
The population in 14 weeks = 232 fishes.
Jaime ran the first 3 1/3 miles of a 5-mile race in 1/3 hour. What was her average rate, in miles per hour, for this first part of the race? Explain how you solved the problem.
9514 1404 393
Answer:
10 mph
Step-by-step explanation:
To find miles per hour, divide miles by hours:
(3 1/3 mi)/(1/3 h) = (10/3)/(1/3) mi/h = 10 mi/h
Jaime's average rate was 10 miles per hour.
if a certain cannon is fired from a height of 8.5 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, In seconds, is found by the function h(t)=-4.9t^2+27.5t+8.5 Find the time it takes for the cannonball to strike the ground.
Answer: 2.88 seconds
Step-by-step explanation:
we need to find t in the formula, when h(t) = 0, (meaning it hits the ground).
0 = -4.9t² + 27.5t + 8.5
Using the quadratic formula:
x = (-b ± √b² - 4ac)/2a
x = (-27.5 ± √27.5² - 4(-4.9)(8.5))/2(27.5)
x = (-27.5 ± 30.38)/55
x = 2.88 OR x = -57.88
Since time cannot be negative, we will stick with the positive answer, 2.88 seconds.
Hope this helped :)

Use the proportion to solve for the unknown base measure of the enlarged trapezoid. 1.Set up the proportion: StartFraction 2 over 3.25 EndFraction = StartFraction x over 6.5 EndFraction 2.Use cross products: 2(6.5) = 3.25(x) 3.Simplify: 13 = 3.25x 4.Divide both sides by 3.25: The missing base measure of the enlarged trapezoid is cm.
Answer:
The missing base measure of the enlarged trapezoid is 4cm.
Step-by-step explanation:
Step 1:
2 / 3.25 = x / 6.5
Step 2:
Cross product
2 * 6.5 = 3.25 * x
Step 3:
Simplify
13 = 3.25x
Step 4:
Divide both sides by 3.25
13 / 3.25 = 3.25x / 3.25
4 = x
x = 4
The missing base measure of the enlarged trapezoid is 4cm.
Answer:

Circle A has a circumference of 25 centimeters. Circle B's diameter is 3 times as long as circle A’s diameter. What is the circumference of circle B?
- And don’t say 10 because it’s wrong
Answer: 74.98cm
Step-by-step explanation:
Step 1: Find out radius of Circle A. [We use circumference of circle A to find its radius].
Circumference of circle A = 2πr; where r is radius.
To better viewing we change sides, we get:
2πr = Circumference of circle A
2πr = 25
r = [tex]\frac{25}{2\pi }[/tex]
r = [tex]\frac{25}{3.14}[/tex]
r ≈ 3.98
Step 2: Calculate the diameter of circle A.
diameter of circle A = 2r = 2(3.98) = 7.96
Step 3: Finding diameter of circle B.
diameter of circle B = 3(diameter of circle A) = 3(7.96) = 23.88
Step 4: Converted diameter of circle B to r.
diameter of circle B = 2r
23.88 = 2r
divided 2 from both sides, we get:
11.94 = r
Step 5: Substitute radius of circle B into the circumference formula, where C = 2πr.
C = 2πr
C = 2(3.14)(11.94)
C ≈ 74.98

How did I get this wrong?
This value is exact
==================================================
Explanation:
Add up everyone in the "has a pet" column to get 22+78 = 100. So we have 100 people who have a pet.
Add up every value in the "male" row to get 22+66 = 88. So there are 88 males
It's tempting to say that 100+88 = 188 people either have a pet or are male, but we're double counting the 22 males who have a pet (top left corner). So we must subtract that value off to get 188-22 = 166
Another way you could look at it is to add up every value that is either in the "has pet" column or is in the "male" row, giving us: 22+78+66 = 166
So there are 166 people who either have a pet, are male, or both.
This is out of 22+66+78+34 = 200 people total
Divide the two values to get 166/200 = 0.83 = 83%

Mark McGuire hit 70 home runs in the 1998 season. Given that there are 4 bases & 90 feet between each base, how many miles did he run that season just from home runs?
Answer:
4.8 or about 5 miles
Step-by-step explanation:
In order to solve this problem, you must first multiply the 4 bases × 90 feet to get how much feet he runs in 1 home run. 4 × 90= 360 feet. Then you must multiply 360 feet × 70 homeruns, this will give you how many feet he ran in 70 homeruns. Your answer will be 25,200 feet. Now, there are 5,280 feet in one mile, so you must divide 25,200 by 5,280. Using a calculator, my answer was 4.7727272727. I then rounded it up to 4.8 miles, or about 5 miles.

Answer:
180 cm²
Step-by-step explanation:
From inspection of the diagram, the surface area is made up of the area of 4 congruent triangles and the area of one square.
Area of a square = x² (where x is the length of one side)
⇒ area of the square = 6² = 36 cm²
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 6 x 12 = 36 cm²
Total surface area = 4 x area of one triangle + area of the square
= 4 x 36 + 36
= 144 + 36
= 180 cm²
Answer:
180 I was the first so could I have brainlyest
Step-by-step explanation:
we need the area of 4 triangles and one square triangle = base x height x 1/2 square = base x height 6 x 6 = 36 + ( 6 x 12 / 2 x 4 = 144) = 180

What is the slope of the line that passes through the points (2, 9)(2,9) and (18, -3)(18,−3)? Write your answer in simplest form.
(2 ; 9) and (18 ; - 3)
slope = (-3 - 9) / (18 - 2) = -12/16 = -3/4 or - 0,75
Slope of the line that passes through the points (2, 9) and (18, -3) is -2.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b
where m is the slope and b is y intercept.
The formula to calculate slope passing through two points (x1, y1) and (x2, y2) is
m= (y₂- y₁)/(x₂-x₁)
The given two points are (2, 9) and (8, -3)
Here x₁=2, y₁=9, x₂=8, and y₂=-3
Substitute the values in formula of slope.
m=-3-9/8-2
m=-12/6
m=-2
Hence slope of the line that passes through the points (2, 9) and (18, -3) is -2.
