Answer:
1.67x10-24
Step-by-step explanation:
The mass of the proton in scientific notation is given by:
[tex]1.67 \times 10^{-24}[/tex]
A number in scientific notation has the following format:
[tex]y = a \times 10^b[/tex]
a is a number in the interval [tex][1, 10)[/tex].b is the power of 10. If the number is greater than 1, the power is positive. If the number is between 0 and 1, the power is negative.In this problem, the number is: [tex]0.00000000000000000000000167[/tex].
To place into scientific notation, we need that [tex]a = 1.67[/tex].Moving the decimal point to after the 1, it would move 24 places, in a number between 0 and 1, thus [tex]b = -24[/tex]Thus, the mass of the proton, in scientific notation, is of:
[tex]1.67 \times 10^{-24}[/tex]

Which compound inequality is equivalent to the absolute value inequality |b| greater than 6? –6 > b and b > 6 b > –6 or b < 6 –6 < b and b > 6 b < –6 or b > 6
Answer:
The correct inequality is: b< -6 or b > 6
Step-by-step explanation:
The absolute value operator always results in a positive number, in such a way that if b > 0, then |b| = b, while if b < 0, then |b| = -b. With this in mind, let's look at the inequality given:
|b| > 6
This will be true for values of b that are greater than 6 and values of b that are less than -6, due to the absolute value operator. Therefore the compound inequality that represents this situation is:
b< -6 or b > 6
Answer:
I think it is D (and)
Step-by-step explanation:
"Or" means that the b value can be less than -6 or greater than 6
so it could satisfy either one
so if you plug in a value that satifies one of the inequalities (ex: -7)

Step-by-step explanation:
Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal
<A = <C
3x+40 =x+50
Subtract x from each side
3x-x+40 = x+50-x
2x +40 = 50
Subtract 40 from each side
2x+40-40=50-40
2x = 10
Divide each side by 2
2x/2=10/2
x = 5
We want to find <A

f(x) = 2(x - 7)2 - 32
(0,-32)
(0,66)
(0,-7)
(0,17)
Answer:
(0, 66 )
Step-by-step explanation:
To find the y- intercept, let x = 0 and solve for y
f(0) = 2(0 - 7)² - 32
= 2(- 7)² - 32
= 2(49) - 32
= 98 - 32
= 66
The coordinates of the y- intercept are (0, 66 )
5. The longest leg of a right triangle is 8 meters and another side is 6 meters. Calculate the
perimeter. 5
Answer:
24 meters
Step-by-step explanation:
Alright. Your question had errors, but I managed to scramble together some answers.
The right triangle has a total of 3 sides, 2 which are 8 and 6. We need to find the hypotenuse.
Let's use the Pythagorean Theorum.
a^2 + b^2 = c^2
8^2 + 6^2 = c^2
64 + 36 = 100
To get c by itself, square root it.
[tex]\sqrt{100} =10[/tex]
You found the hypotenuse :D
Add it up!
8 + 6 + 10 = 24 meters
Answer:
Remember this formula.
Step-by-step explanation:
[tex]\sqrt{a^{2}+b^{2}=c^{2}[/tex]
If your legs are 8 and 6, the last side is the hypotenuse, which is always the largest side of a right triangle. You calculate it's length by taking the measurements of leg A and leg B, and squaring both of them, or raising them both by the power of 2.
This will equal C, or your hypotenuse, but it will be squared, so you have to find its square root to get the actual measurement, which is why the equation has a square root sign over it, so the answer is automatically squared when put into a calculator.
8 x 8 = 64 [or [tex]8^{2}[/tex]]
6 x 6 = 36 [or [tex]6^{2}[/tex]]
[tex]8^{2}+6^{2}=100\\\sqrt{100}=10[/tex]
[tex]\sqrt{8^{2}+6^{2}=10[/tex]

At the beginning of an experiment, there are 600 grams of contaminants. Each hour, half of the contaminants are filtered out. How many grams of contaminants remain after 4 hours?
PLEASE SHOW WORK OR I WON'T MARK YOU THE BRAINLIEST
Answer:
37.5
Step-by-step explanation:
If you cut 600 in half 4 times the first time it will be 300 because 600/2 is 300. The second time it will be 150 because 300/2 is 150. The third time it will be 75 because 150/2 is 75. The fourth time it will be 37.5 because 75/2 is 37.5, so that is the answer.
If this helps please give me brainliest. Thx :)
Answer:
37.5 grams of contaminants remain after 4 hours.

Answer:
6 cube/to the 3rd units
Step-by-step explanation:
um idk if this is what you want but yeah
if you spilt it into a 2x2x1 and a 1x2x1 you can count that there are 6 cube units
Answer:6 cubes
Step-by-step explanation:
There are 2 ways that I think you could solve this.
1. First, you could make those 2 missing cubes actual cubes, so then you could find the volume of the cube by doing 2x2x2(length x width x height) and you would get 8 cubes. After that, you would take away the two missing cubes, and you would get 6 cubes.
2. You could also just count the cubes. I counted the two inner cubes and then counted the 4 outer cubes, and got 6 cubes.
Hope this helps!

No es sano que los perros tengan en la sangre niveles altos de colesterol. Debido a que una dieta rica en grasas saturadas incrementa el nivel de colesterol, es plausible que los perros domésticos tengan niveles más altos que los perros que pertenecen a una clínica de investigación veterinaria. En consecuencia, los niveles de colesterol “normales” basados en los perros de la clínica pueden ser engañosos. Una clínica comparó perros sanos de su propiedad con perros sanos llevados a la clínica para ser esterilizados. Los estadísticos de resumen de los niveles de colesterol en la sangre (en miligramos por decilitro de sangre) son los siguientes: GRUPO N PROMEDIO S Perros domésticos 26 n= promedio=193 s=68 Perros de la clínica n=23 promedio=174 s=44

Dr. Barber needs to pay her employees $15.00 an hour. If she has five
technicians and they each worked 25 hours, how much money in total will Dr.
Barber pay all of the technicians?
Answer:
$1,875
Step-by-step explanation:
$15.00 per hour (multiply by hours)
per technician (multiply by technicians)
so: 15x25=375 then 375x5=1,875
Answer:
$1875
Step-by-step explanation:
First, let's find how many hours the technicians worked
She has 5 technicians, and the each worked 25 hours
We can multiply 5 and 25 to find the total number of hours
5*25=125
Now we know that the technicians worked 125 hours altogether. Now, we need to find how much money that is.
They worked 125 hours, and they are paid $15 per hour
We can multiply 125 and 15 to find the cost
125*15=1875
So, Dr. Barber will pay the technicians $1875 in total
The area of a square is 102 square units. What is an
estimated value for the length of a side of the square?
between 10 and 11
between 11 and 12
between 12 and 13
between 13 and 14
Answer:
Between 10 and 11.
Step-by-step explanation:
To begin, we can look at the problem as such. If we take the first answer choice, we can find the squares of both numbers giving us: (Remember that the area of a square is A=L²)
10²= 100
11²= 121
Since the given area is in between these two numbers, this means that the side length must be between 10 and 11.

Derek uses a 52 inch flat steel bar that weighs 10.4 lbs to make a rack in the garage. Find the weight of a 67-inch steel bar?
Answer:
13.4lbs
Step-by-step explanation:
10.2/52 = 0.2lbs per inch
0.2(67) = 13.4lbs
Using unitary method, the weight of a 67 inch steel bar is 13.4 lbs.
What is unitary method?The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Weight of 52 inch flat steel bar = 10.4 lbs.
Weight of 1 inch flat steel bar = 10.4/52 = 0.2 lbs.
Weight of 67 inch flat steel bar = 0.2 * 67 = 13.4 lbs.

A survey asks a random sample of 2500 adults in Ohio if they support an increase in the state sales tax from 5.25% to 5.50%, with the additional revenue going to education. Let X denote the number in the sample that say they support the increase. Suppose that 30% of all adults in Ohio support the increase.
9. The standard deviation of X is
a. 22.91.
b. 27.39.
c. 5255.
d. 750.
10. The probability that X is at least 800 is
a. less than 0.0001.
b. about 0.015.
c. 0.025.
d. 0.05.
Answer:
Step-by-step explanation:
a) Total number of people surveyed, n = 2500
Let X denote the number in the sample that say they support the increase. If 30% of all adults in Ohio support the increase, it means that the percentage of all adults in Ohio that did not support the increase is
100 - 30 = 70%
This is a binomial probability because there are only two possible outcomes. Therefore,
Probability of success, p = 30/100 = 0.3
Probability of failure, q = 1 - p = 1 - 0.3
q = 0.7
Standard deviation = √npq
Standard deviation = √(2500 × 0.3 × 0.7) = 22.91
b) The probability that x is at least 800 is expressed as
P(x ≥ 800)
We would determine the probability by using the binomial probability calculator. Therefore,
P(x ≥ 800) = 0.01577
b. about 0.015.
