Lisa can harvest a field in 9.3 hours. Kali can harvest
the same field in 9.7 hours. Find how long it would take
them if they worked together.
Answer:
4.75 hours
Step-by-step explanation:
First you need to find the median of the two numbers. The fastest way to do it is to add 9.3 and 9.7 and divide by 2, which will give you 9.5. Since there's going to be two of them working, divide 9.5 by 2, and you get 4.75.
1/9.3 + 1/9.7 = 1/x
x=4.74789

what is the area of the triangle
Answer:
36
Step-by-step explanation:
There are several ways to find area of triangle from vertex coordinates, the easiest is: (x₁*(y₂-y₃) + x₂*(y₃-y₁) + x₃*(y₁-y₂)) / 2
Area = ((-1)*(-6 - -6) + (-6)*(-6 - 2) + (3)*(2 - -6)) / 2
= (0 + 48 + 24) / 2
= 72/2
= 36

Which of the following demonstrates the Commutative Property of Multiplication?
5(2a − 3) = 10a − 15
10a − 15 = (2a − 3) ⋅ 5
5(2a − 3) = (2a − 3) ⋅ 5
(5 ⋅ 2a) − 3 = 5(2a − 3)
Answer:
C
Step-by-step explanation:
Because the Commutative Property means: Changing the order of factors does not change the product.
Therefore, the answer is C; 5(2a-3)=(2a-3)x5.

If a skateboarder skates down a ramp for 3 seconds,and his initial velocity was 0.8 m/s and his final velocity was 7 m/s.Then what was his acceleration.
Newtons First Equation of motion can be applied and plugin in the given data the acceleration was found to be 2.03 m/s^2
Velocity, Acceleration and Time
Given Data
Time t= 3 seconds
Initial Velocity u = 0.8 m/s
Final Velocity v = 7 m/s
Acceleration a = ??
Applying the Newton's First equation of motion
v = u+at--------------1
Substituting our given Data
7 = 0.8+a*3
solving for acceleration a
7-0.9 = 3a
6.1 = 3a
divide both sides by 3 we have
a = 6.1/3
a = 2.03 m/s^2
Answer a = 2.03 m/s^2

Solve the following equations:
a. 3x + 5y = 8 ,
4x – 3y = 1
b. 6p + 4q = 20,
5p – 2q = 6
Step-by-step explanation:
a) 3x + 5y = 8
4x - 3y = 1
• using the elimination method:
3x + 5y = 8 (×4)
4x -3y = 1 (×3)
12x + 20y = 32
12x -9y = 3
subract 12x from both equation:
20y - - 9y= 32 -3
20y +9y = 29
29y= 29
y= 29/29
y= 1
- substituting y= 1 in :
4x - 3y= 1
4x - 3(1) = 1
4x -3 = 1
4x = 1 + 3
x = 4/4
x= 1
b) 6p+ 4q = 20
5p - 2q = 6
• using the elimination method:
6p + 4q = 20
5p - 2q = 6 (×2)
6p + 4q = 20
10p - 4q = 12
add 4q + -4q to eliminate q.
6p+ 10p = 20+12
16p = 32
p = 32/ 16
p = 2
- subtituting p = 2 in :
5p - 2q = 6
5(2) -2q =6
10 -2q = 6
-2q = 6 - 10

The surface area of a paper cup is defined by the function S(h) = 4π√(16 + h^2) where h is the height of the cup. What are domain and range of f(x)?
I already know the answer but I want to know the steps.
Answer:
No h-intercept/zero
Step-by-step explanation:
1- Substitute the s (h) = 0
2- Determine the defined range
3- the statement is false for any value of h
4- There is no h-intercept/zero
All the real numbers are the domain of the function. Then the range of the function will be [16π, ∞).
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The domain means all the possible values of x and the range means all the possible values of y.
The equation that represents the surface area of the paper cup is given below.
S(h) = 4π√(16 + h²)
Where h is the height of the cup.
The graph of the equation is drawn below. Then all the real numbers are the domain of the function.
And the lowest point of the function will be given as,
S(0) = 4π√(16 + 0²)
S(0) = 4π√16
S(0) = 16π
Then the range of the function will be [16π, ∞).

Scott tossed a wad of paper. It landed in
а
the trash can 3 times and missed 2 times.
Based on these results, how many times
would Scott expect the wad of paper to
land in the trash can if he throws it 60
times?
A. 20
B. 36
C. 40
D. 48
Answer:
36 times.
Step-by-step explanation:
3/5=0.6
2/5=0.4
60*0.6=36
Scott would expect the wad of paper to land in the trash can approximately 36 times out of 60 throws. So, correct option is B.
To calculate the expected number of times the wad of paper would land in the trash can if Scott throws it 60 times, we can use the concept of probability.
Based on the given results, the probability of the wad of paper landing in the trash can is 3 out of 5 times (3 times in the trash can out of a total of 5 throws).
To find the expected number of successful throws (i.e., landing in the trash can) out of 60 throws, we can set up a proportion:
(Probability of success) = (Number of successful throws) / (Total number of throws)
3/5 = x/60
Now, cross-multiply and solve for 'x':
5x = 3 * 60
5x = 180
x = 180 / 5
x = 36
The correct answer is B. 36
This calculation is based on the assumption that the probability remains the same for each throw, which is the case for independent events like tossing a wad of paper.

What is the area of this trapezoid?
Answer:
Area of trapezoid = 19.84 in^2
Step-by-step explanation:
Area of trapezoid = (b1+b2)/2 * Height
to find the height we have to use the Pythagorean formula for the left triangle
[tex]X^2 + Y^2 = Hypotenuse^2[/tex]
we sub the values in the formula
[tex]3^2 = Y^2 + 4^2[/tex]
Y = [tex]\sqrt{7}[/tex] which the height of the triangle
now we sub the values in the trapezoid formula
Area of trapezoid = (5+10)/2 * sqrt{7}
Area of trapezoid = 19.84 in^2

Emma doesn't have experience using credit cards. In fact, she just got her first one. She is also about to start her first year
of college. She uses her new credit card to purchase textbooks for her classes. The total comes to $300. These are the
terms of her credit card:
• It has a 15% annual interest rate.
• The interest is compounded monthly
• The card has $0 minimum payments for the first four years it is active.
The expression that models this situation is P(1 + r/n)^nt, where (1 + r/n) represents the growth factor of the interest rate.
Answer:
P = $300
r = 0.15
n = 12
$544.61 (to the nearest cent)
[tex]P(1+r)^t[/tex]
$524.70 (to the nearest cent)
Step-by-step explanation:
P = principal amount = $300
r = annual interest rate in decimal form = 15% = 15/100 = 0.15
n = number of times interest is compounded per unit t = 12
How much she'll owe in 4 years
P = 300
r = 0.15
n = 12
t = 4
[tex]P(1+\frac{r}{n})^{nt}=300(1+\frac{0.15}{12})^{12 \times 4}[/tex]
