Answer:
Option (A) is the answer.
Answer:
A. 115t + 7,600 ≤ 28,000
Step-by-step explanation:
First, you see that the answer to the question has to show that 115t plus or minus 7,600 has to be less than 28,000 because that is how much the neighborhood group has of money to spend. So, that narrows the answers to a or c. The correct answer would be answer A because you need to add 115t and 7,600 because both of those two numbers are the costs for the improvements of the park. Therefore, the correct answer would be A. 115t + 7,600 ≤ 28,000.
find the average rate of change, in simplest form, of the function over the interval 4\le x \le 74≤x≤7.
Answer:
[tex]Average\ Rate = \frac{104}{3}[/tex]
Step-by-step explanation:
Given
See attachment for table
Required
Determine the average rate of change over: 4≤x≤7.
Average rate of change is calculated as:
[tex]Average\ Rate = \frac{f(b) - f(a)}{b - a}[/tex]
Where:
[tex]a=4[/tex]
[tex]b = 7[/tex]
So:
[tex]Average\ Rate = \frac{f(b) - f(a)}{b - a}[/tex]
[tex]Average\ Rate = \frac{f(7) - f(4)}{7 - 4}[/tex]
[tex]Average\ Rate = \frac{f(7) - f(4)}{3}[/tex]
From that table:
f(4) =
f(7) =
So:
[tex]Average\ Rate = \frac{f(7) - f(4)}{3}[/tex]
[tex]Average\ Rate = \frac{108-4}{3}[/tex]
[tex]Average\ Rate = \frac{104}{3}[/tex]

A scientist has a sample of bacteria that initially contains 10 million microbes. They observe the sample and finds that the number of bacterial microbes doubles every 20 minutes. Which exponential function represents M, the total number of bacterial microbes in millions, as a function of t, the number of minutes the sample has been observed?
Answer:
M(t) = 6.7 * 10⁷ (67 million)
Minutes (t) =55
Step-by-step explanation:
1. Write an exponential equation that represents M, the total number of bacterial microbes in millions, as a function of t, the number of minutes the sample has been observed.
For answering this question, we will use the following formula:
M(t) = B₀ * g ^(t/m), where:
•M(t) represents the total number of bacterial microbes in millions.
• B₀ represents the initial population of bacteria in millions.
• g represents the growth factor.
• t represents the total number of minutes we will observe the bacteria growing.
• m represents the time in minutes it takes to the growth factor g to occur.
2. Then, determine how much time, to the nearest minute, will pass until there are 67 million bacterial microbes.
M(t) = B₀ * g ^(t/m)
Replacing with the values we know:
6.7 * 10⁷ = 10⁷ * 2 ^(t/20)
6.7 = 2 ^(t/20) (Dividing by 10⁷ at both sides)
ln 6.7 = ln 2 ^(t/20)
ln 6.7 = t/20 ln 2
ln 6.7/ ln 2 = t/20
t = ln 6.7/ln 2 * 20
t = 2.74 * 20
t = 54.88
t ≅ 55 (rounding to the nearest minute)

Gas from a local station costs $2.85 per gallon (in US dollars). Tara's car gets 13.4 kilometers to the liter.
About how much will it cost Tara to drive 640 kilometers if she buys the gas from that local gas station?
Answer:
$250.8
Step-by-step explanation:
13.4 = $2.85
13.4 x 15 = 111.0
111.0 = $42.75
111.0 x 6 = 666.0
666.0 - 26.0 = 640.0
$42.75 x 6 = $256.5
$2.85 x 2 = $5.07
$256.5 - $5.07 = $250.8
not gona lie this took forever lol
Hope this helps if so don't hesitate to 'Thanks' and/or 'brainliest' this answer!
The total cost of 640 liters of gas is $35.91.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, Gas from a local station costs $2.85 per gallon (in US dollars).
We know that, 1 gallon = 3.785 liters
Tara's car gets 13.4 kilometers to the liter.
Number of liters of gas = 640/13.4
= 47.76 liters
Number of gallons = 47.76/3.785
= 12.6 gallons
Total cost = 12.6×2.85
= $35.91
Therefore, the total cost of 640 liters of gas is $35.91.

The points (-1,r) and (11, -1) lie on a line with slope 3/4
Find the missing coordinate r.
Answer:
The value of the missing coordinate 'r' is -10
Step-by-step explanation:
The two points have the following given parameters;
The point coordinates = (4, -17) and (8, r)
The line on which the two points rests has a slope of, m = 3/4
To find the value of 'r', we use the slope formula as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Plugging in the values gives;
[tex]m = \dfrac{3}{4} = \dfrac{-1-r}{11-(-1)} =\dfrac{-1-r}{11 + 1} = \dfrac{-1 - r}{12}[/tex]
[tex]\dfrac{3}{4} =\dfrac{-1 - r}{12}[/tex]
∴ 3 × 12 = 4 × (-1 - r)
36 = -4 - 4·r
36 + 4 = -4·r
r = 40/(-4) = -10
r = -10

63+90+2x+11=180
Answer:
B
Step-by-step explanation:
Add 63 and 90 to find the left angle. Then subtract by 180.
Since that answer is 27, add it to 90 and subtract by 180 to find the last angle in the middle. then finally the angle in the corner should equal 27 since the triangles are congruent.

Which of the following sets of numbers could not represent the three sides of a triangle?
Answer:
It would be {10, 16, 27}, {12, 27, 39}, {8, 22, 31} that DO NOT represent 3 sides of a triangle
Step-by-step explanation:
Since the only answer where the first 2 numbers is greater than the 3rd/last number is {14, 28, 39} (which makes it the only traingle), the others would ALL NOT be triangles.
Answer:
Options A, D
Step-by-step explanation:
The way that we will be checking if these 3 numbers can represent a triangle is by checking if a + b ≥ c. That means that the first two sides have to be greater than or equal to the third side.
Step 1: Determine if Option A is a triangle
10 + 16 = 26 <- 26 is less than 27 that means that it cannot form a triangle.
Step 2: Determine if Option B is a triangle
14 + 28 = 42 <- 42 is greater than 39 which means that these three numbers can form a triangle.
Step 3: Determine if Option C is a triangle
12 + 27 = 39 <- 39 is equal to 39 which means that these three numbers can form a right triangle.
Step 4: Determine if Option D is a triangle
8 + 22 = 30 <- 30 is less than 31 meaning that these three numbers can't form a triangle.
Answer: Options A, D

The base of a triangular pyramid is 21 inches squared. The volume is 63 inches cubed. What is the height of the pyramid?
Answer:
9
Step-by-step explanation:
So the formula for a triangular pyramid is v=1/3bh
you plug in the values and you get 63=1/3(21)(h) and since you are finding the height, you get h=63*3/21
and then you check answers with
63=1/3(21)(9) which is true so the height is 9

a cylindrical shaped container is 8 in. tall with a diameter of 6 in. How much water could this container hold?
Answer:
226.08 in
Step-by-step explanation:
To find how much water this container can hold, we should find the volume of this container.
Volume of cylinder = πr²h
= 3.14 × 3² × 8 (r= d/2 => 6/2 = 3)
= 226.08 in
Answer:
226.19 in³ or .979 gallons
Step-by-step explanation:
The problem is asking for volume.
First, you must get the radius
d represents diameter
r = d/2
r = 6/2
r = 3
Now, you can calculate for the volume
Volume formula for cylinder
V = πr²h
V = π(3)²(8)
V = 226.19 in³ or .979 gallons

x = 36°
Step-by-step explanation:
Every triangle equals 180°
That means
a + b + c = 180
With each letter representing each angle.
So...
47 + 97 + x = 180
Add 47 and 97
144 + x = 180
Subtract 144 from both sides to isolate x
x = 36
