On a road trip a family drives 350 miles per day how many days D must they travel to reach the distance of at least 1400. Solve the inequality what does the solution represent in this situation?
(Just in case you wanted to see the question I put a picture)
Answer:
[tex]350 * D \geq 1400[/tex]
[tex]D\ge 4[/tex]
This means that the family must travel for at least 4 days.
Step-by-step explanation:
Given
[tex]Rate = 350\ miles\ daily[/tex]
[tex]Distance = 1400\ miles\ (atleast)[/tex]
Required
Determine and solve the inequality
The number of days is represented with D
So:
On any D number of days, the family would have covered a distance of 350 * D miles
If the total distance is at least 1400, then the inequality is:
[tex]350 * D \geq 1400[/tex]
[The term "At least" is used to represent greater than or equal to]
[tex]350 * D \geq 1400[/tex]
Divide through by 350
[tex]\frac{350 * D}{350} \ge \frac{1400}{350}[/tex]
[tex]D \ge \frac{1400}{350}[/tex]
[tex]D\ge 4[/tex]
This means that the family must travel for at least 4 days.

If angle 4 is x + 15 and angle 2 is 3x - 5, what is the
value of x?
Answer:
I cant tell what u mean but if the angles are equal the answer is 10
Step-by-step explanation:
Based on the calculations, the value of x is equal to 42.5.
Given the following data:
Angle 4 = x + 15.Angle 2 = 3x - 5.To determine the value of x:
What is a supplementary angle?A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees.
Mathematically, a supplementary angle is calculated as follows:
[tex]Angle\;2+Angle\;4 =180\\\\3x-5 +x+15=180\\\\4x+10=180\\\\4x=180-10\\\\4x=170\\\\x=\frac{170}{4}[/tex]
x = 42.5.

Complete the table shown to the right for the half life of a certain radioactive substance.
Decay rate:1.5% per year=-0.015
The half life is ___ years
Given:
Decay rate: 1.5% per year = -0.015
To find:
The half life.
Solution:
The continuous exponential decay function is
[tex]A(t)=Ae^{-kt}[/tex]
where, a is initial value, -k is decay rate and t is time period.
For half life, [tex]A(t)=\dfrac{A}{2}[/tex],
[tex]\dfrac{A}{2}=Ae^{-0.015t}[/tex]
Dividing both sides by A.
[tex]\dfrac{1}{2}=e^{-0.015t}[/tex]
Taking natural log on both sides.
[tex]\ln \dfrac{1}{2}=\ln e^{-0.015t}[/tex]
[tex]-0.69314718=-0.015t[/tex]
Divide both sides by -0.015.
[tex]\dfrac{-0.69314718}{-0.015}=t[/tex]
[tex]46.209812 =t[/tex]
[tex]t\approx 46[/tex]
Therefore, the half life is 46 years.
If the drawing length is 7 cm. and the real length is 28 metres , then drawing scale is what

Have a nice Day , I would appreciate it if you could mark my answer brainliest
The drawing should have a scale of 400:1.
What is scale?A scale is a group of levels or numbers that are applied to a certain system of measurement or comparison.
Given, the drawing length is 7cm and the real length is 28 meters.
real length in cm = 2800. hence,
Scale of drawing = 2800: 7 = 400 : 7
Therefore, 400: 1 would be the scale of the given drawing.

Step-by-step explanation:
A(-4, 5) => A'(-4+2, -5) = A'(-2, -5)
B(-6, -4) => B'(-6+2, -(-4)) = B'(-4, 4)
C(4, -4) => C'(4+2, -(-4)) = C'(6, 4)
Hence the new coordinates are A'(-2, -5), B'(-4, 4) and C'(6, 4).

Step-by-step explanation:
so the point [tex](\sqrt{3},\sqrt{7})[/tex] is in the circumference so the distance from (0,0) to this point will be the radius of the bullseye
[tex]x=\sqrt{(\sqrt{3}-0)^2+(\sqrt{7}-0)^2}\\\\x=\sqrt{3+7}\\\\x=\sqrt{10}[/tex]
so that's the radius
so the area will be
[tex]A=\pi x^2\\\\A=\pi (\sqrt{10})^2\\\\A=10\pi[/tex]
so the percentage is
[tex]P=\frac{A}{1600}\\\\=\frac{10\pi}{1600}\\\\=\frac{\pi}{160}\\\\P\approx 0.02[/tex]
so it's 2%
