Answer:
x=140
Step-by-step explanation:
A quadralterial interior angles sum up to 360. We are given three angles and need to find the missing angle.
Let x, represent the missing angle.
[tex]60 + 55 + 105 + x = 360[/tex]
[tex]220 + x = 360[/tex]
[tex]x = 140[/tex]

help guys plz i suck at math, also step by step is needed Branliest is the reward like always
Answers
Answer:
2.9195
Step-by-step explanation:
To find the time we need to equate the function the zero and solve for t:
[tex] { - 16t}^{2} + 45t + 5 = 0[/tex]
Using the general formula we have that:
[tex]t = \frac{ - 45 + \sqrt{ {45}^{2} - 4 ( - 16)(5)} }{2( - 16)} \\ = \frac{ - 45 + \sqrt{2345} }{ - 32} [/tex]
then:
[tex]t = \frac{ - 45 + \sqrt{2345 } }{ - 32} = - 0.107 \\ or \\ t = \frac{ - 45 - \sqrt{2345} }{ - 32} = 2.9195[/tex]
Since the time has to be positive we conclude that the ball is in the air 2.9195 seconds.

Which graph represents the function f(x) = 3/2(2)x
Answers
The fourth graph represents the function [tex]f(x)=\frac{3}{2} 2^{x}[/tex]
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given function is [tex]y=\frac{3}{2} 2^{x}[/tex]
It is an exponential function and 2>1, therefore it is an increasing in nature.
put x=0 in the given function to find the y-intercept of the graph.
f(0)=3/2.2⁰
f(0)=3/2(1)
f(0)=3/2=1.5
So, the y-intercept is 1.5.
In figure 1 and figure 1 the y-intercept is 1, in figure 2 the y-intercept is 2 , therefore first three options are incorrect.
In figure 4 the y-intercept is 1.5, therefore the option 4 is correct.
Hence, the fourth graph represents the function [tex]f(x)=\frac{3}{2} 2^{x}[/tex]

Keith needs to build a bridge to go across a pond. He has been able to collect the following measurements. About how long does this bridge need to be
Answers
Answer:
[tex]\Huge\boxed{11.9}[/tex]
Step-by-step explanation:
Hello There!
Basic Concepts
Geometry
Once again we are going to need to use trigonometric ratios to solve for a missing side length (the length of the bridge)
Here are the trigonometric ratios
Sine - Opposite over Hypotenuse
Cosine - Adjacent over Hypotenuse
Tangent - Opposite over Adjacent
For the angle that has a measure of 50 degrees
we are given its adjacent side length and we need to find its opposite
When working with the opposite side length and adjacent side length we use the trigonometric ratio tangent
Knowing which trigonometric ratio we are going to use we have to create an equation
Remember tan = opposite over adjacent
So we plug in the given information and solve for the missing information ( In this case the opposite side length)
[tex]tan(50)=\frac{x}{10}[/tex]
Basic Algebra
Now we solve for x
Like always we want to isolate the variable
First we want to get rid of the 10
x is being divided by 10 and the inverse of division is multiplication
So we multiply each side by 10
[tex]tan50*10=10tan50\\\frac{x}{10} *10=x\\[/tex]
now we have
[tex]10tan50=x\\[/tex]
finally we plug in 10tan50 into a calculator to get the value of x
we get that x = 11.91753594
Our last step is to round to the nearest tenth
We can conclude that the answer is 11.9
The bridge needs to be 11.92 feet long by calculating the tangent of the given angle.
What is tangent of an angle?Tangent of an angle in a right-angled triangle is the ratio of the height to the base of the triangle.
Let, the bridge is x ft. long.
Therefore, tan 50° = [tex]\frac{x}{10}[/tex].
⇒ x = 10 × tan 50°
⇒ x = 10 × 1.192
⇒ x = 11.92
Therefore, the bridge is 11.92 ft. long.

Janine and her older sister Ingrid's ages are consecutive even numbers. When Janine's age is divided by seven, and Ingrid's age is divided by three, the sum of those numbers is fourteen. How
old are Janine and Ingrid?
Answers
Answer:
Janine is 28. Ingrid is 30.
Step-by-step explanation:
Let the ages be x and x + 2 for Janine and her sister, respectively.
x/7 + (x + 2)/3 = 14
Multiply both sides by the LCD, 21, to get rid of denominators.
21 * x/7 + 21 * (x + 2)/2 = 21 * 14
3x + 7(x + 2) = 294
3x + 7x + 14 = 294
10x = 280
x = 28
x + 2 = 30
Answer: Janine is 28. Ingrid is 30.
Answer:
Janine is 28 and Ingrid is 30.
Step-by-step explanation:
Let Janine's age be x years , then Ingrid's age is x+2 years.
From the given information we have the equation:
x/7 + (x + 2)/3 = 14
Multiplying through by the LCM of 3 and 7 (21), we have:
3x + 7(x + 2) = 294
10x + 14 = 294
10x = 294-14 = 280
x = 28, so:
Janine is 28 and Ingrid is 30.

Answers
Answer:
19
Step-by-step explanation:
Rearranging the number in ascending order,
12,15,17,19,19,20,24,26
Median = The average of the 4th and 5th number
[tex] = \frac{19 + 19}{2} \\ = 19[/tex]
Answer:
19
Step-by-step explanation:
so first you have to order the values from least to greatest.
12, 15, 17, 19, 19, 20, 24, 26
there are 8 terms (note that 2 of them are 19)
n = 8
median = (n + 1) ÷ 2
=(8 + 1)/2
=9/2 = 4.5
it's 19 because the median falls between those two (19) data points.
