PLEASE HELP. 8(n + 4) + 3n > 2(n - 2)
Answer:
n>-4
Step-by-step explanation:
8(n + 4) +3n > 2(n -2)
8n+32+3n > 2n-4
9n>-36
n>-4
Answer:
n > -4
Step-by-step explanation:
8(n + 4) + 3n > 2(n - 2)
Solve for inequality
_________________
To solve, we need to isolate the variable :
Distribute :
(8(n) + 8(4)) + 3n > (2(n) - 2(2))
8n + 32 + 3n > 2n - 4
Add like terms :
11n + 32 > 2n -4
Subtract 2n from both sides :
9n > -36
Divide 9 from both sides :
n > -4

Answer:
B
Step-by-step explanation:
The sum to n terms of a geometric series is
[tex]S_{n}[/tex] = [tex]\frac{a(1-r^{n}) }{1-r}[/tex]
where a is the first term and r the common ratio
Here a = 6144 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{3072}{6144}[/tex] = [tex]\frac{1}{2}[/tex] , then
[tex]S_{10}[/tex] = [tex]\frac{6144(1-(\frac{1}{2}) ^{10}) }{1-\frac{1}{2} }[/tex]
= [tex]\frac{6144(1-\frac{1}{1024}) }{\frac{1}{2} }[/tex]
= 12288(1 - [tex]\frac{1}{1024}[/tex] ) ← distribute
= 12288 - 12
= 12276 → B

A jet flies due North far a distance of 50 cm and then on a bearing of N TOE for a furter
km. Find the distance and bearing of the jet from its starting point
Answer:
90 km, N 46° E
Step-by-step explanation:
A jet flies due North for a distance of 50 km and then on a bearing of N 70° E for a further 60 km. Find the distance and bearing of the jet from its starting point.
Look at the diagram I drew of this scenario. You can see the jet flies North for 50 km, and then turns at a 70° angle to fly another 60 km. We want to find the distance from the starting point, SP, to angle C (labeled).
This will be the jet's distance from its starting point.
In order to find the bearing of the jet from its starting point, we will need to find the angle formed between distances b and c, labeled angle A.
The Law of Cosines will allow us to use two known sides and one known angle to solve for the sides opposite of the known angle.
In this case, the known angle is 110° (angle B) so we will use the Law of Cosines respective to B.
b² = a² + c² - 2ac cosBSubstitute the known values into the equation and solve for b, the distance from the starting point (A) to the endpoint (C).
b² = (60)² + (50)² - 2(60)(50) cos(110°)b² = 6100 -(-2052.12086) b² = 8152.12086b = 90.28909602b ≈ 90 kmThe distance of the jet from its starting point is 90 km. Now we can use this b value in order to calculate angle A, the bearing of the jet.
The Law of Cosines with respect to A:
a² = b² + c² - 2bc cosASubstitute the known values into the equation and solve for A, the bearing from the starting point (clockwise of North).
(60)² = (90.28909602)² + (50)² - 2(90.28909602)(50) cosA 3600 = 8152.12086 - 6528.909602 cosA-4552.12086 = -6528.909602 cosA0.6972252853 = cosA A = cos⁻¹(0.6972252853) A = 45.79519A ≈ 46°The bearing of the jet from its starting point is N 46° E. This means that it is facing northeast at an angle of 46° clockwise from the North.
A trapezoid has an area of 35 square inches. It has a base of 8 inches and 6
inches. What is the height of the trapezoid?
the height of the trapezoid of 5, i think.
my work:
i used this formula: 2 x a + b / A
so, you plug in what you know.
2 x 8+6 / 35 = 5
A trapezoid has an area of 35 square inches, a base of 8 inches & 6 inches. the height of the trapezoid is, 5 inches
What is the area?An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².
Given that,
A trapezoid has an area of 35 square inches
It has a base of 8 inches and 6 inches
the height of the trapezoid = ?
Area of trapezoid = 1/2 × sum of sides × distance between them
= 1/2 × (8 + 6) × h
35 = 7 × h
h = 5
Hence, the height is 5 inches

Find the original price given the total amount and the tip rate.
Total amount: $51.84
Tip: 20%
Answer:
62.208
Step-by-step explanation:
51.84 + 10.368
Answer:
I think if the total amount was $51.84 after tax, then 51.84 x 0.20 = 10.368. $51.84 - 10.368 = $41.472
I think original price was $41.47. I am not sure.

The dimensions of a rectangle are 2x – 5 and 3x + 3. Which expression
represents the area of the rectangle in simplest form?
Answer: 2x - 5
Step-by-step explanation: 2x - 5 does not have anything in common, so therefore it can not be simplified. Then 3x - 3 can be divided by 3 because they have that in common. It can’t be 3x - 3 because it still contains one step left to be in its most simplified form.

A random sample of size 16 is to be taken from a normal population having mean of 100 andvariance 4. What is the 90th percentile of the distribution of x?
The 90th percentile of the distribution of x is 100.64.
Given that,
A random sample of size 16 is to be taken from a normal population having mean of 100 and variance 4calculation:Here we have
[tex]n=16,\mu=100,\sigma^{2}=4[/tex]
Now we requried z-score that has 0.90 area to its left. z-score 1.28 has 0.90 area to its left.
So required 90th percentile is
[tex]z=\frac{\bar{x}-\mu}{\sigma/\sqrt{n}}\\\\1.28=\frac{\bar{x}-100}{2/\sqrt{16}}\\\\\bar{x}=100.64[/tex]

Given:
[tex]\to n=16\\\\\to \mu=100\\\\ \to \sigma^{2}=4[/tex]
To find:
distribution [tex]\bar{x}=?[/tex]
Solution:
We require a z-score with such a 0.90 area to its left in this case. The area to the left of the z-score 1.28 is 0.90. As a consequence, the required 90th percentile is
Using formula:
[tex]\to z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}}\\\\[/tex]
[tex]\to 1.28=\frac{\bar{x}-100}{\frac{2}{\sqrt{16}}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{2}{\sqrt{4^2}}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{2}{4}}\\\\\to 1.28=\frac{\bar{x}-100}{\frac{1}{2}}\\\\\to 1.28=\frac{\bar{x}-100}{0.5}\\\\\to 0.64 =\bar{x}-100\\\\\to \bar{x}=100+0.64\\\\\to \bar{x}=100.64\\\\[/tex]

Answer:
1) x = 12
2) x = 2
Step-by-step explanation:
Because each figure is a parallelogram, we know that the opposite sides are congruent. Now, we set 12 equal to 2x - 12 to solve. For number one, x = 12. For number two, we set 5x + 1 equal to -1 + 6x to solve. This equals 2.

Solve for xxx. -30=5(x+1)
First, apply the distributive property:
-30 = 5(x + 1)
-30 = 5x + 5
Substract 5 from both sides:
-30 - 5 = 5x + 5 - 5
-35 = 5x
Divide both sides by 5:
[tex]\mathsf{\dfrac{-35}{5} = \dfrac{5x}{5}}[/tex]
[tex]\large{\boxed{\mathsf{-7 = x}}}[/tex]
Let's check the answer:
-30 = 5(x + 1)
-30 = 5(-7 + 1)
-30 = 5(-6)
-30 = -30
The answer is correct.
