The equation F= 9/5 C+32 relates temperature measured in degrees Celsius, C , to degrees Fahrenheit, F. Determine whether there is a proportional relationship between C and F.
Answer:
The relationship between F and C is proportional
Step-by-step explanation:
The relationship between Celsius and Fahrenheit temperatures is a direct proportionality. Both scales have their ice and steam points as well as their fundamental intervals.
When the temperature in Celsius increases, the temperature in Fahrenheit increases and vice versa.

how much time will it take for the plane to land?
Answer:
Again assuming we're cleared for immediate take off, it takes around 20 minutes to climb to cruise altitude, at an average ground speed of (say) 200 knots. This means we've covered about 70 miles, which the cruising aircraft would have covered in just over 10 minutes. So this final phase has cost us another 10 minutes

WILL MAKE BRAINLIEST! Let sin 21 = 0.358. What is the value of x for cos x = 0.358
Answer:
The value of x is 69°
Step-by-step explanation:
In a right angle triangle, if m and n are the two acute angles on it, then
m + n = 90° sin(m) = cos(n)cos(m) = sin(n)That means if sin(m) = cos(n), then m + n = 90°
Let us use these facts to solve the question
∵ sin(21°) = 0.358
∵ cos(x°) = 0.358
→ That means sin(21°) = cos(x°)
∴ sin(21°) = cos(x°)
→ By using the facts above
∴ 21 + x = 90°
→ Subtract 21 from both sides
∵ 21 - 21 + x = 90 - 21
∴ x = 69°
∴ The value of x is 69°

find the circumference of each circle round to the nearest tenth
Answer:
7) 75.4 yd
8) 34.56 mi
6) 81.68 cm
Step-by-step explanation:
The formula of circumference is: circumference (C) = 2 * π * r
7) The radius = 12 yd
π = 3.14
We can solve for C:
C = 2πr
C = 2(3.14)(12 yd)
C = 75.4 yd
8) The radius = 5.5 mi
π = 3.14
Solve for C:
C = 2πr
C = 2(3.14)(5.5 mi)
C = 34.56 mi
6) The diameter is 26. The radius is one half of the diameter; so the radius is 13.
We can solve for C:
C = 2πr
C = 2(3.14)(13 cm)
C = 81.68 cm
Hope this helpsss <3
Answer:
7) 75.36 8)34.54 9)81.64
Step-by-step explanation:
you can find this by using the formula diameter times pi (for pi use 3.14) or the formula 2times pi times radius. and for the diameter just multiply the radius by 2.

Systems of equations, solve by substitution please!
x + 7y = -37
4x - 3y = 7
Step-by-step explanation:
make the coefficients same
then if sign are same subtract the one you wanna cancel it then here it goes
lam gonna start making coefficient of x sam like this:
4.X+7y= -37
1.4X-3y=7
then i will subtract all x or cancel to each other then
4X+28y= -148
-
4X-3y=7
and then -×-=+
add all y
31y=141
y= 4.55 then we take one of the equation then substitute y to 4.55 so i chose first equation
X+7(4.55)=-37
X+31.85=-37
so take 31.85 to the side it will become -31.85
then X=-37-31.85
X=68.85
i hope that it will help you

Algebraically determine whether the following function is Even, Odd, or Neither.
f(x)= x^3-2x
Answer:
f(-x)= -f(x) so, the given function [tex]f(x)= x^3-2x[/tex] is Odd
Step-by-step explanation:
We need to determine if the function [tex]f(x)= x^3-2x[/tex] is Even, Odd, or Neither.
Determining if a function f(x) is even or not we put x=-x and check
If f(-x)=f(x) the function is even
if f(-x)= -f(x) the function is odd
So, Putting x =-x and determining if the given function [tex]f(x)= x^3-2x[/tex] is Even, Odd, or Neither.
[tex]f(x)= x^3-2x\\Put \ x=-x\\f(-x)=(-x)^3-2(-x)\\f(-x)=-x^3+2x\\f(-x)=-(x^3-2x)\\f(-x)=-f(x)[/tex]
As f(-x)= -f(x) so, the given function [tex]f(x)= x^3-2x[/tex] is Odd

Cara deposited $200 dollars into her savings account bringing her balance up to $450. Which equation can be used to find, x, the savings account balance before the $200 deposit?
A x + 200 = 450
B x200=450
C x−200=450
D 200x = 450
Answer:
A. x + 200 = 450
Step-by-step explanation:
Since clara deposited $200 into her savings account and it brought her account up to $450, to find the answer you would add "x" with 200 and you should get 450 which means x= 250. we can check our answer by solving : 450-200 and you should get 250 for your answer so the answer is
A x + 200 = 450

Step-by-step explanation:
Whitney has £265 Nancy has £180 They each spend the same amount of money. Whitney has twice as much money as Nancy left now. How much money did they each spend?
Answer:
£95
Step-by-step explanation:
Given that:
Whitney's initial amount = £265
Nancy's initial amount = £180
Let amount each spent = x (amount is the same)
After spending Whitney has twice as much money as Nancy.
Amount spent by each?
(Whitney's initial amount - x) = 2(Nancy's initial amount - x)
265 - x = 2(180 - x)
265 - x = 360 - 2x
-x + 2x = 360 - 265
x = £95
Hence, they both spent £95

Compute the average for the 9 months
Answer:
$71.01Step-by-step explanation:
What is the average of a set of numbers?
An average is a number expressing the central or typical value in a set of data, in particular the mode, median, or (most commonly) the mean, which is calculated by dividing the sum of the values in the set by their number.
Given
September, $28.95;
October, $46.15;
November, $68.46;
December, $109.34;
January, $115.26;
February, $94.19;
March $75.66;
April, $51.97; and
May, $49.16.
Step two:
Total amount= 28.95+46.15+68.46+109.34+115.26+94.19+75.66+51.97+49.16= 639.14
Total number of monts= 9
Average= 639.14/9
Average= $71.01

Lee is selling spirit wear for a fundraiser hats cost $8 and shirts $12 lee sold $272 worth of spirit wear in the first month. If lee sold a total of 28 items how many hats did Lee sell
Lee sold 16 hats.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
Cost of 1 hat= $8
Cost of shirt = $12
Total cost of spirit wear= $272
let the number of hats sold be x
and, let the number of shirts sold be y
So, 8x+ 12y= 272
and, x+ y= 28
Solving the above equations we get
8(28- y) + 12y= 272
224 - 8y + 12y = 272
4y = 48
y = 12
and x= 28- 12 = 16
Hence, Lee sold 16 hats.
