Melbourne is a popular tourist location in Florida. The highest temperature ever recorded there was 109°F. The lowest temperature recorded there was 20°F. Write two inequalities that would describe the temperature, in °F, in Melbourne at any time since temperatures have been recorded.
The inequality that shows the temperature in Melbourne is 20°F ≤ x ≤ 100°F
What is an inequality?
An inequality is an expression that shows the non equal comparison of two or more variables and numbers.
Let x represent the temperature in Melbourne.
The highest temperature ever recorded there was 109°F, hence x ≤ 109°F.
Also, the lowest temperature ever recorded there was 20°F, hence x ≥ 20.
From both statements:
20°F ≤ x ≤ 100°F
The inequality that shows the temperature in Melbourne is 20°F ≤ x ≤ 100°F

Answer:
15s
Step-by-step explanation:
s+4. + s +4. + s+7 =15s
Find a line that is perpendicular to y = 2/5x-1 that goes through (3,6)
To find a line perpendicular to the original line, we must set the new slope as the negative reciprocal of the original slope, 2/5.
So the slope of the perpendicular line is -5/2
Now using the point slope form, we have the slope -5/2 and (3,6)

60PTS Chef Alfredo invested $4800 at a simple interest rate of 5% and can now afford a $6,000
state-of-the-art pizza oven. How many years ago did he make this investment? show step by step explanation
Answer:
An oft-repeated water vapor myth is that warm air can “hold” more water vapor than cool air because as the air warms its molecules move farther apart, making room for more molecules.
Step-by-step explanation:
The requried Chef Alfredo made this investment 5 years ago.
What is simple interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan.
Amount = Principal [1 + rate×time]
Here,
We can use the formula for simple interest to find out how long it would take for Chef Alfredo's investment to grow to $6,000.
I = P * r * t
We know the following,
P = $4800
r = 5% = 0.05
I = $6000 - $4800 = $1200
Substituting these values into the formula,
$1200 = $4800 * 0.05 * t
t = $1200 / ($4800 * 0.05)
t = 5 years
Therefore, Chef Alfredo made this investment 5 years ago.

Step-by-step explanation:
The triangle will be a right triangle when the side lengths satisfy the Pythagorean theorem: the sum of the squares of the legs is equal to the square of the hypotenuse.
(x +1)^2 +x^2 = (√61)^2
x^2 +2x +1 +x^2 = 61 . . . eliminate parentheses
2x^2 +2x = 60 . . . . . . .subtract 1, collect terms
x^2 +x -30 = 0 . . . . . divide by 2, subtract 30
(x +6)(x -5) = 0 . . . . factor the quadratic
x = -6 or +5
The solution is x = 5.

Side lengths cannot be negative. Solution values are values of x that make the factors zero. x+6=0 when x=-6, for example.

8d+2t
Add it all together:
8d+2t+4
Answer:
2t+8d+4
Step-by-step explanation:
If I am doing this correctly we would put 2t and 8d to the side since there is nothing similar to it
Then we would-4+8 which would be 4

The volume of a right cone is 21 pi units. If its circumference measures 6 pi units, find its height.
Given,
Volume of cone = 21π cm³
& It's Circumference = 6π
Find Radius,
★ Circumference = πr²
=> 6π = πr
=> 6π/π = r
=> r = 6 cm
Now,
★Volume of cone = 1/3πr²h
[tex] = > 21\pi = \frac{1}{3} \times 36\pi \times h \\ = > 21\pi = 12\pi \times h \\ = > \frac{21\pi}{12\pi} = h \\ = > \frac{7}{4} = h \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = > h \: = 1.75 \: cm[/tex]★Hence, The value of height is 1.75 cmHope it helps youu....!!!
Through the volume of the cone we will calculate the height, so we find that:
h=1.75 cm
How to calculate the volume of the cone?The volume of the cone is calculated by multiplying the area of the base and the height. Since the base is a circle, we use the formula for the area of a circle times the height of that cone.
Organizing the information given in the statement we have:
Volume of cone = 21π cm³ Circumference = 6πRadius = 6knowing the formula of the volume is:
[tex]V = 1/3\pi r^2h\\(21\pi )= 1/3 \pi (6)^2h\\h= 1.75[/tex]

Cones A and B are similar.
The volume of cone A is 1080cm3.
The volume of cone B is 1715cm3.
Calculate the height,
h
, of cone A.
Answer:
1715= 1/3 x 3.14 x r x r x 63
= 65.94 x r^2
÷65.94
26.01 = r^2
Square root
Radius is 5.1
1080 = 1/3 x 3.14 x 5.1^2 x h
1080 = 27.22 x h
÷27.22
39.67 = h
(Haven't been actually rounding up in my calculation, when I divided.)
Check:
1/3 x 5.1^2 x 39.67 x 3.14 = 1079.968146.
So, height is about 39.67cm

Answer:
-6
Step-by-step explanation:
So, this problem wants you to multiply 5x+1 with 2x-3 and place it in ax^2 + bx + c form and add a. b, and c all together.
So, let's start by multiplying the expressions together
( 5x + 1 )( 2x - 3 ) = 5x ( 2x - 3 ) + 1(2x - 3)
= 10x^2 - 15x + 2x -3
= 10x^2 - 13x -3
There, we have our answer of 10x^2 - 13x - 3
So, a = 10, b = -13, and c = -3
a + b + c = 10 -13 - 3
= -6
