Answer:
y = -6 + 1.2*x is the answer I would use, but see the note below.
Step-by-step explanation:
Let x = the number of minutes.
Let y = the temperature at any given time.
y = -6 + 1.2*x
This is the equation that you would use if you were calculating y with a calculator. If you are in a chemistry class it should be written as
y = - 6°C + 1.2°x/ min
25 POINTS. Radar used microwaved yo check the speed of cars. If a speed of the microwaves is 2 000 000 m/ s and the wavelength is 0.0345m calculate the frequency.
Answer:
57971014.49 Hz or 5.79 * 10^7 Hz
Step-by-step explanation:
Given that:
Speed of microwave (v) = 2,000,000 m/s
Wavelength, λ = 0.0345 m
Frequency :?
Using the relation :
v = fλ
f = v / λ
f = 2,000,000 / 0.0345
f = 57971014.49 Hz
The area of the rectangle is 27 square feet. Choose the equation you can use to find the value of x. A rectangle. The length is x feet and the width is 3 feet. $3x=27$ $2x+6=48$ $27x=3$
Answer:
3x = 27
Step-by-step explanation:
Since the area of a rectangle, A = lw where l = length = x and w = width = 3 feet. So, A = 3x. Since A = 27 square feet, 27 = 3x.
So, the required equation is 3x = 27

Hey you ‼️ yeah I unfortunately need your help again these are hard:(
Answer:
Step-by-step explanation:
The point of this question is to find out the point where two lines intersect. First we need to get the equation of those lines
Slope of line 1:
(Yb -Ya)/(Xb - Xa) =
(-10 - (-14))/(-1 - (-3)) =
4/2 =
2
Use that slope to find the Y-intercept of line 1
y = 2x + b
-14 = 2(-3) +b
-14 = -6 + b
-8 = b
Therefore Line 1 is:
y = 2x - 8
Slope of line 2
(11 - 13)/(-1 - (-3)) =
-2/2 =
-1
Y-intercept of line 2
y = -x + b
13 = -(-3) +b
13 = 3 + b
10 = b
Therefore line 2 is
y = -x + 10
Now we have 2 equations to solve for the coordinates x and y
y = 2x - 8
y = -x + 10
Substitute y out in one of the equations
2x - 8 = -x + 10
3x = 18
x = 6
Plug x into one of the equations
y = 2(6) - 8
y = 12 - 8
y = 4
Therefore the solution is:
x=6, y=4
Find the solution to the inequality 10-x>2

Answer:
y^6
Step-by-step explanation:
It can help to remember that an exponent is simply an indicator of repeated multiplication. Common factors cancel from numerator and denominator.
[tex]\dfrac{y^7}{y}=\dfrac{y\cdot y\cdot y\cdot y\cdot y\cdot y\cdot y}{y}=y\cdot y\cdot y\cdot y\cdot y\cdot y=\boxed{y^6}[/tex]

Written as a rule of exponents, this is ...
(a^b)/(a^c) = a^(b-c)
Of course, a = a^1.
A triangle has a side length of 4 inches and an area of 18 square inches and a larger similar triangle has a corresponding side length of 8 inches
24 square inches
72 square inches
48 square inches
Answer:
yes it is
Step-by-step explanation:
need help which one is it
a)x=7
b)x=12
c)x=20
- you can use the pythagorean theorem for this.
a^2 + b^2 = c^2
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
- square root this.
c = 20
therefore, x = 20.
so option C.
Answer:
c. X = 20
Step-by-step explanation:
Pythagoras theorem
a² + b² = c²
12² = 144
16² = 256
144 + 256 = 400
√400 = 20

Answer:
$190
Step-by-step explanation:
Step one:
Given data
Chick Hicks buys 20 car stickers for $760.
let us find the cost of one sticker
cost of one sticker= 760/20
cost of one sticker=$38
