Describe a situation in the real world, where at least three types of science would be used to solve a problem. Use details to support your answer.
Answer:
Running
There are many different types of science that go into running, including the following:
Psychology (think you can/can't do it, how tired you are, how much further you can go/how much further you think you can go, dissociating and distracting, associating and motivating, etc.)
Physiology (how fit one is, training, etc.)
Nutrition (food/drinks that are put into one's body, vitamins, etc.)
Physics ("The greater the force Fx, the greater the horizontal running velocity, and the longer the arc length, hence the faster the runner will run. Arm swinging is an important part of running. It serves to stabilize the body" - Real World Physics Problems (.com))
Newton's Three Laws (gravity, inertia, friction, net force exerted, equal and opposite reactions, etc.)
Biology (Chemical balance in your blood)
And more!
And remember: everything connects with something else, for example, nutrition can connect with all of the things on this list (yes, even phycology and physics). Hope this helps! :-)

At Kennedy High School, the probability that a student takes Technology and Spanish is
0.087. The probability that a student takes Technology is 0.68. What is the approximate
probability that a student takes Spanish given that the student is taking Technology?
0.13
Explanation:
P(B|A) = P(A and B) / P(B)
P(spanish|Technology) = 0.087/0.68 = 0.1279 ~ 0.13
The probability that a student takes Spanish given that the student is taking Technology is; 0.13
To solve this, we need to understand Baye's theorem of conditional probability which is;
P(A|B) = P(AB)/P(B)
Where;
P(A|B) is the probability of A given that B is true
P(AB) is probability of A & B
P(B) is probability of B
We are given;
P(A student takes technology) = 0.68
P(student takes both technology and Spanish) = 0.087
Applying Baye's theorem, we have;
P(that a student takes Spanish given that the student is taking Technology) = 0.087/0.68
P(that a student takes Spanish given that the student is taking Technology) = 0.13

Eric wants to send a package to his mother. If he chooses UPS, the fixed express fee is 10 dollars and each kilogram costs 2 dollars. For Fedex, the fixed fee is 20 dollars and each kilogram costs only 1 dollar. If the total costs of the two options are the same, how many kilogram of package does Ericsend? Write a system of equations in order to solve this problem.
Answer:
10kg
Step-by-step explanation:
For UPS;
express fee = $10
If one kg costs $2, then x kg of package will coat $2x
Total cost of shipping xkg of package will be 10+2x
For FedEx;
Fixed express fee = $20
If one kg costs $1, then x kg of package will coat $1x
Total cost of shipping x kg of package is 20+x
If the total costs of the two options are the same, then;
10+2x = 20+x
2x-x = 20-10
x = 10.
Hence Eric sent 10kg of package

Beth enlarged the triangle below by a scale of 5.
A triangle with a base of 4 centimeters and height of 3.5 centimeters.
She found the area of the enlarged triangle. Her work is shown below.
One-half (4) (3.5) (5) = 35 centimeters squared
What was Beth’s error?
Answer: She should have multiply each of the sides the scale value before multiplying to find the area.
Step-by-step explanation:
They are two sides to the triangle which is the base and the height and each side have a different length so you will have to first multiply each side length by the scale value to find the new length of the enlarged triangle.
base: 4 *5 = 20
height : 3.5 * 5 = 17.5
Now since the base is 20 cm and the height is 17.5 cm you will use the area of a triangle formula to solve for the area.
A = 1/2* b * h
A = 1/2 * 20 * 17.5
A = 10* 17.5
A = 175
or she could have multiply 35 which is the number he obtained by another 5 to find the area.

what is the LCM of 6,4,10
6 has a factor of 2 and 3
4 has a factor of 2
10 has a factor of 2 and 5
The LCM = 60
Answer:
60
Step-by-step explanation:
The LCM is the lowest common multiple, this means the smallest number that 6, 4 and 10 can go into without giving a decimal number, so they give an integer.
Here's a trick, use prime factorizationPrime factorization means, write a number as the result of the multiplication of prime numbers prime numbers are numbers with only two factors, 1 and itselfSo the prime factorization of 6, 4 and 10 is6 = 2 x 3 4 = 2 x 210 = 2 x 5For each prime factor, find where it occurs most often as a factor and write it that many times in a new list. So 2 occurs most often as a factor of 4, so we use two 2s3 occurs most often as a factor of 6, so we use one 35 occurs most often as a factor of 10, so we use one 5Then multiply this new list of numbers 2 x 2 x 3 x 5 = 60 that's how you quickly get the LCM6s-4=8 (2+ 0.25s)

The track is 3/5 of a mile long. If Tyrone jogged around it twice, how far did he run?
He ran for 6/5 miles long.
What is multiplication?In maths, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The two factors and the product are parts of a multiplication problem.
Given that, Tyrone run on a 3/5 long track for twice.
3/5*2 = 6/5
Hence, He ran for 6/5 miles long.

Find the required annual interest rate, to the nearest tenth of a percent, for $ 1170 to grow to $ 1708
if interest is compounded quarterly for 6 years.
A) 6.4%
B) 1.6%
C) 3.2%
D) 7.9%
Answer:
Step-by-step explanation:
The formula you need for this is
[tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex]
where A(t) is the final amount after the compounding is done, P is the initial investment, r is the interest rate in decimal form, n is the number of times per year that the money is compounded, and t is the time in years. Filling in accordingly:
[tex]1708=1170(1+\frac{r}{4})^{(4)(6)}[/tex]
First things first. Simplify by division and then multiply the n by the t to get the exponent:
Divide 1708 by 1170 to get the equation:
[tex]1.45982906=(1+\frac{r}{4})^{24}[/tex]
Undo the 24th power by taking the 24th root of both sides to get:
[tex]1.015888202=1+\frac{r}{4}[/tex] Now subtract 1 from both sides to get
[tex].0158882024=\frac{r}{4}[/tex] Multiply both sides by 4 to finish it off and get that
r = .0635528 but since we want the percentage, we move the decimal 2 places to the right and round to r = 6.4% which is choice A.

At what point are the prices of the two services the same?

Step-by-step explanation:
Answer:
The prices of the two services are the same when two movies have been rented
Step-by-step explanation:
We can figure out at what point the two services cost the same by using the y=mx+c formula
James:
y=2x+6
Sarah:
y=3x+4
We then figure out at what point are the two services the same by making the equations equal each other and then solve from their
3x+4=2x+6
3x+4-2x=2x+6-2x
x+4-4=6-4
x=2
Therefore the price of the two services are the same when 2 movies have been rented

Answer:
y = -4x - 6
Step-by-step explanation:
slope-intercept form: y = mx + b
Given: Slope: -4
Point: (-2, 2)
To write an equation in slope-intercept form, we need to know the slope(m) and the y-intercept(b). Since we were given the value of the slope, all we have to do now is find b. To do this, input the given values of m and the point into the equation and solve for b:
y = mx + b
2 = -4(-2) + b
2 = 8 + b
-6 = b
The y-intercept is -6.
Now that we know the slope and the y-intercept, we can write the equation:
y = -4x - 6
