Answer:
x = 78 /5
Step-by-step explanation:
5(x+4)=12-40-7x
Subtract the numbers from the left side which will equal -25-7x
Then... Distribute the -5 to x and 4 making the equation on the left
-5x -20
In all your equation should look like this
-5x -20 = -25 -7x
Then add 7x to the right side and add 20 to the left making the equation
-5x + 7x = -28 + 20
The add up the terms on each side...
2x = -8
Then divide the 2 to the left side...
Overall:
x= -4

A model car is built to a scale of 1 in. : 2.5 ft. If the model is 5.8 in. Long how long is the car in real life?
Answer:
14.5 ft
Step-by-step explanation:
We are told that the model car is built to a scale of 1 in. : 2.5 ft.
That means 1 inches represents 2.5 ft in actual measurement.
Thus, for a 5.8 inch long model, the real life measurement is;
(5.8 inch × 2.5 ft)/1 inch = 14.5 ft

Solve for y.
3x + 4y = z
-----------------
Answer:
y= z-3x/4
Step-by-step explanation:
4y=z-3x
y=z-3x/4
Answer:
[tex]y=\frac{z-3x}{4}[/tex]
Step-by-step explanation:
[tex]3x+4y=z[/tex]
Subtract 3x from both sides:-
[tex]3x+4y-3x=z-3x[/tex]
[tex]4y=z-3x[/tex]
Divide both sides by 4:-
[tex]\frac{4y}{4}=\frac{z}{4}-\frac{3x}{4}[/tex]
[tex]y=\frac{z-3x}{4}[/tex]

Answer:
D i believe.
Step-by-step explanation:
Hope this helps :)
The equation with the greatest growth factor is d(t) = 400 . 3^t
Correct option is D.
As per the given data:
Equations representing the number of bacteria in four different dishes as a function of time, t in days, are given.
To find out the equation with the greatest growth factor:
Growth Factor = Term whose power is raised to t.
For option (A), Growth Factor = (5/6) = 0.834
For option (B), Growth Factor = (1/50) = 0.02
For option (C), Growth Factor = (5/2) = 2.5
For option (D), Growth Factor = (3) = 3
Hence, the equation with the greatest growth factor is d(t) = 400 . 3^t

A set of average city temperatures in December are normally distributed with a mean of 16.3 degrees C and a standard deviation of 2 degrees C.
∘What proportion of temperatures are between 12.9 degrees C and 14.9 degrees C?
you may round your answer four decimal places.
Answer: 0.1974
Step-by-step explanation:
z1 = (12.9 - 16.3)/2 = (-3.4)/2 = -1.7
Z2 = (14.9 - 16.3)/2 = (-1.4/2) = -0.7
“Z table”
Z1= -1.7 ~ 0.0446
Z2 = -0.7 ~ 0.242
0.2420 - 0.0446= 0.1974
what is m?
please help
Given:
[tex]\Delta ABC\sim \Delta QRS[/tex]
To find:
The missing value of m.
Solution:
We have,
[tex]\Delta ABC\sim \Delta QRS[/tex]
Corresponding parts of similar triangles are proportional.
[tex]\dfrac{AB}{QR}=\dfrac{AC}{QS}[/tex]
Putting the given values, we get
[tex]\dfrac{m}{10}=\dfrac{2}{4}[/tex]
[tex]\dfrac{m}{10}=\dfrac{1}{2}[/tex]
Multiply both sides by 10.
[tex]\dfrac{m}{10}\times 10=\dfrac{1}{2}\times 10[/tex]
[tex]m=5[/tex]
Therefore, the value of m is 5.
Julie works at a pizza place in Phoenix. She receives a 15% discount on any pizza that she buys. If a large pizza costs $14.00, what is the amount of Julie’s discount? What is the final cost of her pizza?
Answer:
The final cost of her pizza is $11.90
Step-by-step explanation:
First we need to convert 15% into a decimal, which is 0.15.
Now we multiply $14 and 0.15.
$14 × 0.15 = $2.10.
Now we subtract $2.10 from $14.00.
$14.00 - $2.10 = $11.90

Alright, archtan /
tan

(
x
)
is the inverse of tangent. Tan is
sin
cos
. Like the inverse of sin, the inverse of tan is also restricted to quadrants 1 and 4.
Knowing this we are solving for the inverse of tan -1. We are basically being asked the question what angle/radian does tan(-1) equal. Using the unit circle we can see that tan(1)= pi/4.
Since the "Odds and Evens Identity" states that tan(-x) = -tan(x). Tan(-1)= -pi/4.
Knowing that tan is negative in quadrants 2 and 4. the answer is in either of those two quadrants. BUT!!! since inverse of tan is restricted to quadrants 1 and 4 we are left with the only answer -pi/4.
