What is the value of x?
(2x - 5)°
n
l
m 45°
Answer: x = 70
Step-by-step explanation: the sum of the angle 2x-5 and 45 deg should equal 180 deg, so 2x-5 should be equal to 135 because 180 - 45 = 135
So 2x -5 = 135. Add 5 to both sides to cancel it out. 2x = 140. divide both sides by 2 to cancel 2 on x. Answer is X=70

what is the remainder when 5^400 is divided by 19
The remainder when [tex]5^{400}[/tex] is divided by 19, the remainder is 17.
Remainder
The Remainder is the value left after the division. If a number (dividend) is not completely divisible by another number (divisor) then we are left with a value once the division is done. This value is called the remainder.
We can write,
[tex]5^{400} = (5^4)^{100} = 625^{100}[/tex]
We know that,
19*33 = 627
Hence, we can write 625 as 627 - 2
It will become,
[tex]\frac{(627-2)^{100}}{19}=\frac{(-2)^{100}}{19}[/tex]
We know that, even power of any number and its negative counterpart will be same.
Hence, we can write,
[tex]\frac{(-2)^{100}}{19}=\frac{(2)^{100}}{19} = \frac{2*2^{99}}{19}[/tex]
We know that 99 = 11*9
Hence, we can write,
[tex]\frac{2*({2^9})^{11}}{19} =\frac{2*512^{11}}{19}[/tex]
We know that,
19*27 = 513
Hence, we can write, 512 as 513 - 1
[tex]\frac{2*(513-1)^{11}}{19}=\frac{2(-1)^{11}}{19}[/tex]
2*(-1)/19 = -2/19

if three sides of an equilateral triangle measures 3X +12, 8X -3 and 5Y plus one what is the value of X and Y in the length of each side
The value of X and Y in the length of each side of an equilateral triangle is X = 3 and Y = 4
In this question we have been given the equations for the three sides of an equilateral triangle.
3X +12, 8X -3 and 5Y + 1
We need to find the value of X and Y.
We know that all sides of an equilateral triangle are equal.
so, 3X +12 = 8X -3 = 5Y + 1
Consider 3X +12 = 8X -3
3X -8X = - 3 - 12
-5X = - 15
X = 3
Now consider an equation 8X - 3 = 5Y + 1
substitute above value of X in this equation.
8(3) -3 = 5Y + 1
24 - 3 = 5Y + 1
21 - 1 = 5Y
5Y = 20
Y = 4
Therefore, the value of X and Y in the length of each side of an equilateral triangle is X = 3 and Y = 4

84. the centers for disease control and prevention reported in 2012 that 1 in 88 american children had been diagnosed with an autism spectrum disorder (asd). a. if a random sample of 200 american children is selected, what are the expected value and standard deviation of the number who have been diagnosed with asd?
a) The expected value is calculated to be 2.273 and b) the standard deviation is 1.499 if a random sample of 200 children is selected.
According to the report 1 in 88 American children has been diagnosed with ASD, therefore the probability can be given as;
p = 1 / 88
a) the expected value can be calculated as follows;
E (X) = n × p
here n = sample size = 200
p = probability = 1 / 88
E (X) = 200 × 1 / 88
E (X) = 2.273
b) To find the standard deviation, first, we have to determine the variance of the random variable;
V (X) = n × q × p
V (X) = 200 × 87/88 × 1/88
V (X) = 2.2468 = 2.247
Now we can calculate the standard deviation as follows;
standard deviation = √V(X)
standard deviation = √2.247
standard deviation = 1.499
Therefore, the expected value and standard deviation are calculated to be 2.273 and 1.499 respectively.

A computer base unit of mass 4.5 kg is dragged along smooth desk, if tension in each arm of the person dragging it is 16 N and acts at 22° above the horizontal, then what is the normal reaction force is 32.12N.
What is a force?A force is effect that can alter an object's motion according to physics. A force can cause an object with mass to accelerate when it changes its velocity, for as when it moves away from the rest. An obvious way to describe force is as push or a pull. A force is vector quantity since it has both magnitude and direction. It is calculated by using newton SI unit (N). Force is denoted by letter F. (formerly P).
The net force acting on object is equal to the rate at which its momentum varies over time, according to Newton's second law in its original formulation. This law suggests that object's acceleration is directly proportional to the net force acting on it, is in the direction of the net force, and is inversely proportional to mass of the object if the object's mass is constant.

As per the tangent angle, the value of x in the given diagram is 7cm.
Tangent angle
The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Given:
Here we have the two right angled triangle, through this we have to identify the value of x.
According to the given question, we have a diagram with two right angled triangles.
Now, in the upper right angled triangle
tan 50° = opposite side / 5
⇒ 1.19 = 0pposite side/ 5
⇒ opposite side = 1.19 × 5
⇒ opposite side = 1.2 × 5
⇒ opposite side = 6cm
Now, the opposite side with respect to the angle 50 degrees in the upper right angle triangle is a adjacent side according to angle 38 degrees in the lower right angle triangle.
So, in the lower right angle triangle.
tan 38° = x / adjacent side
⇒ 0.78 = x/6
⇒ x = 0.78 × 6
⇒ x = 4.68
⇒ x = 7cm
Hence, the value of x in the given diagram is 7cm.

15 Hannah took a trip to visit her cousin. She drove
120 miles to reach her cousin's house and the same
distance back home. It took her 1.2 hours to get
halfway to her cousin's house. What was her
average speed, in miles per hour, for the first 1.2
hours of the trip? Hannah's average speed for the
remainder of the trip to her cousin's house was 40
miles per hour. How long, in hours, did it take her
to drive the remaining distance? Traveling home
along the same route, Hannah drove at an average
rate of 55 miles per hour. After 2 hours her car
broke down. How many miles was she from home?
Distance was 10 miles away from home.
What is Distance ?
The measurement of distance is the separation between two objects or points, and it can be quantitative or occasionally qualitative. Distance can refer to a physical length in physics or to an estimate based on other factors in ordinary language.
For a journey to see her cousin, Hannah traveled. She traveled 120 miles one way to visit her cousin and 120 miles the other way to return home.
She traveled halfway to her cousin's home in 1.2 hours.
That is 120 / 2 = 60 miles
(Speed = distance/time) 60 miles in 1.2 hours
Average speed = 60 / 1.2
= 50 mph.
For the remainder of the journey to her cousin's home, Hanna's average speed was 40 miles per hour.
Another 60 kilometers remain: Time (= Distance/Speed)
Time = 60/40
= 1.5 hours.
Hanna averaged 55 miles per hour when she made her way home along the same path. Her automobile broke down after two hours.
Find the distance traveled at 55 mph in 2 hours. (Distance = time * speed)
Distance = 55 * 2 = 110miles
So distance from home will be,
= 120 - 110
= 10 miles
Hence, she was 10miles away from her home

PLEASE HELP!! It's easy i'm just Dum. Solve for x, look down below for more info.
By using the fact that the two angles are vertical angles, we will write and solve a linear equation to fine that the value of x is 20.
How to find the value of x?Here we assume that both of the horizontal lines are parallel. Then the two marked angles (the ones that depend of x) are vertical angles.
This means that the measure of these angles is the same one, then we can write:
(5x - 8)° = (3x + 32)°
So we can solve that linear equation to find the value of x, we will get:
5x - 8 = 3x + 32
Grouping like terms we get:
5x - 3x = 32+ 8
2x = 40
x = 40/2
x = 20

There is a 70.6% chance that none of the 4 randomly picked people share your zodiac sign.
Probability is a branch of mathematics in which we determine how likely an event is to happen. It is used when we are not sure about the result or outcome of an event so we consider the probabilities of certain outcomes.
In this case, there are 12 zodiac signs, out of which one is yours. So the probability or chance that the 4 randomly picked people do not share your zodiac sign can be determined as follows;
Probability of one person not having your zodiac sign: 11/12
Probability of 4 people not having your zodiac sign;
11/12 × 11/12 × 11/12 × 11/12 = 0.706
Converting it into percentage:
0.706 × 100 = 70.6%
Hence, the probability that none of the 4 people share your zodiac sign is calculated to be 70.6%.
