20-34+ 8/2 =? PLS HELP ME I GIVE ALL MY POINTS.
Answers
Answer:
-10
Step-by-step explanation:
20-34=-14, 8/2 is just 4, so add 4 to -14 which = -10
8/2=4
then we know our new equation looks like 20-34+4=x. now we need to add.
34+4=38
now we have the new equation 20-38.
20-38=-18
your answer is -18.

If there are 180 grams of radioactive material with a half-life (decrease by half or 50%) of 1 hour, how much of the radioactive material will be left after 3 hours?
Answers
Answer:
After 3 hours there is left 22.5 grams of radioactive material.
Step-by-step explanation:
We can calculate the mass of radioactive material remaining after 3 hours, by using the decay equation:
[tex]N_{t} = N_{0}*e^{-\lambda t}[/tex] (1)
Where:
[tex]N_{0}[/tex]: is the initial mass = 180 g
[tex]N_{t}[/tex]: is the remaining mass after time t
λ: is the decay constant
The decay constant is given by:
[tex] \lambda = \frac{ln(2)}{t_{1/2}} [/tex]
Where [tex]t_{1/2}[/tex] = 1 h.
By entering λ into equation (1) we hve:
[tex] N_{t} = N_{0}*e^{-\frac{ln(2)}{t_{1/2}} t} [/tex]
[tex] N_{t} = 180 g*e^{-\frac{ln(2)}{1 h} 3 h} = 22.5 g [/tex]
Therefore, after 3 hours there is left 22.5 grams of radioactive material.

Answers
Let us consider,
A special [tex]8-[/tex]sided die is marked with the numbers [tex]1[/tex] to [tex]8[/tex].
The odd numbers on the die are [tex]1,3,5,7.[/tex]
The even numbers are [tex]2,4,6.[/tex]
For the experimental sequence of [tex]15[/tex] rolls.
There are [tex]9[/tex] odd number out of 15, which is [tex](3,5,7,1)[/tex].
So the experimental probability is,
[tex]\frac{9}{15} =\frac{3}{5} \\\\=0.60\\[/tex]
[tex]\implies0.60=60[/tex] %
The theoretical probability given that there are odd numbers [tex](1,3,5,7)[/tex] out of [tex]8[/tex] on the dice should be [tex]50[/tex] % because [tex]\frac{1}{2}[/tex] of the numbers are prime.
Thus,
The theoretical probability is [tex]50[/tex] % .
Then,
[tex]60[/tex]%[tex]-50[/tex]%[tex]=10[/tex]%
Hence, the experimental probability of rolling an odd number is [tex]60[/tex]%, which is [tex]10[/tex] % more than the theoretical probability [tex]50[/tex]%.

What is the rate of change or slope?

m=-2/1
m=-1/2 or m=-2/4
m=-2/1 or m=-4/2
Answers
Answer:
m=-1/2 or m=-2/4
Step-by-step explanation:
The rate of change or slope of the given line is [tex]m=-\frac{1}{2} or m=-\frac{2}{4}[/tex]
Given :
The graph of a line . To find out the slope or rate of change , we pick two points on the line.
Two points are (-8,2) and (4,-4)
Lets apply slope formula
[tex]Slope = \frac{y_2-y_1}{x_2-x_1}[/tex]
(-8,2) is (x1,y1)
(4,-4) is (x2,y2)
Substitute all the values inside the formula
[tex]Slope = \frac{y_2-y_1}{x_2-x_1}\\slope =\frac{-4-2}{4+8} =\frac{-6}{12} =-\frac{-2}{4} =-\frac{1}{2}[/tex]
The rate of change or slope of the given line is [tex]m=-\frac{1}{2} or m=-\frac{2}{4}[/tex]

Which statement is true about the two lines whose equations are given below?
A. The lines are parallel.
B. The lines are perpendicular.
C. The lines intersect but are not perpendicular.
D. The lines coincide.
Answers
Answer: C. The lines intersect but are not perpendicular.
Step-by-step explanation:
The correct option is C, the lines intersect but are not perpendicular.
How to determine the equation of the line?To determine which statement is true about the two lines whose equations are given below:
y = 3x + 2
y = -4x + 9
We can compare the slopes of the two lines. The slopes of these lines are 3 and -4 respectively.
Two lines are parallel if and only if their slopes are equal. Since the slopes of these lines are not equal, we can eliminate options A.
Two lines are perpendicular if and only if the product of their slopes is -1. The product of the slopes of these lines is -12, which is not equal to -1. Hence, we can eliminate options B.
Since the lines are neither parallel nor perpendicular, they intersect. To determine whether they intersect perpendicularly, we can compute the angle between them using the slopes.
The angle between two lines is given by the formula:
[tex]tan \theta = \dfrac{(m_2 - m_1)}{ (1 + m_1m+_2)}[/tex]
where m₁ and m₂ are the slopes of the two lines.
Substituting the slopes of the given lines, we get:
[tex]tan \theta = \dfrac{|(-4 - 3)} { (1 + (3 \times -4))|} \\[/tex]
tanθ = 7 / 11
Therefore, the correct option is C: the lines intersect but are not perpendicular.

4 + d = 6; 2
I need help with this answer dose am
Answers
The value of d is 2.
We are provided with the following equation,
4 + d = 6
We are supposed to find the value of d in the above equation.
To solve the equation we need to apply basic mathematical operations. The steps that need to be followed to simply this equation are mentioned below,
4 + d = 6
To get the value of d we need to subtract 4 from both the sides of this equation. On substracting 4 from both the sides of this equation, we will get
4 + d - 4 = 6 - 4
⇒ d = 6 - 4
⇒ d = 2
Thus, the value of d in the equation 4 + d = 6 is 2.

the two shorter sides in a right triangle have the same length . the area of the right triangle is 7.36 square meters. what is the length of the hypotenuse
Answers
The length of the hypotenuse is 5.426 meter
Let the two shorter sides of the right angles triangle be denoted as x meters.
The formula for the area of right triangle is given as,
A = ab/2
Where, a and b are the length of the shorter sides of the triangle
Also we have been given the area of the triangle which is 7.36 sq. meter
Thus , A = 7.36
x^2/2 = 7.36
x^2 = 14.72
x = 3.84
Now according to the Pythagoras theorem,
H = √P^2 + B^2
Where, H = hypotenuse
P = perpendicular
B = base
Now putting the required values we get
H = √x^2 + x^2
= √2x^2
= x√2
= 5.426 meter
Hence the length of the hypotenuse is 5.426 meter
