Answer: x= 19.5
(4x+12) = 90
Step-by-step explanation:
Notice the denoted right angle at the very top left. This means those intersecting lines are perpendicular forming 90 degree angles. All right angles are equal in measure so all 4 angles at the top are 90 degrees. We can then use corresponding angles to know that all of the bottom 4 angles are also 90 degrees. Now we can solve for x. (4x+12) =90. 4x= 78. X= 19.5

One side of a rectangle is 3 yards longer than twice the length of another side. If the perimeter is 27 yards, what is the length of the longer side
Answer:
10 yards
Step-by-step explanation:
;)
The required length of the longer side is 10 yards.
What is the perimeter?Perimeter, is the measure of the figure on its circumference.
Here,
Let's assume that the length of one side of the rectangle is x yards. According to the problem, the other side of the rectangle is 3 yards longer than twice the length of this side. So, the length of the other side can be expressed as 2x + 3 yards.
The perimeter of a rectangle is the sum of the lengths of all its sides. So, we can write an equation to represent the problem:
Perimeter = 2 × length + 2 × width
Substituting the expressions for length and width, we get:
27 = 2(x) + 2(2x + 3)
27 = 2x + 4x + 6
27 = 6x + 6
21 = 6x
x = 3.5
So, the length of one side of the rectangle is 3.5 yards. The other side of the rectangle is 2(3.5) + 3 = 10 yards.
Therefore, the length of the longer side is 10 yards.

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.

is plane A or B faster
Answer:
The slope of the graph of plane A is 430, its speed is 430 miles per hour.
The slope of the graph of plane B is 460, its speed is 460 miles per hour.
Plane B is flying faster.
Step-by-step explanation:
The speed of the airplane is the slope of the function, that is, change in distance by change in time. From table, we notice that curve is a first order polynomial, also known that linear function:
Plane A
The slope of the graph of plane A is 430, its speed is 430 miles per hour.
Plane B
The slope of the graph of plane B is:
[tex]v = \frac{1840\,mi-460\,mi}{4\,h-1\,h}[/tex]
[tex]v = 460\,\frac{mi}{h}[/tex]
The slope of the graph of plane B is 460, its speed is 460 miles per hour.
Therefore, plane B is flying faster.

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]
Learn more about the population here: https://brainly.com/question/905400?referrer=searchResults
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]
Therefore, the answer is "100.64".

What is the sum of the first 10 terms of this geometric series? Use

OA. 11,520
OB
12,276
OC. 23,040
OD. 24,550
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

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.
