Answers
Answer: x = 2.4 or 12/5, y = -1.2
Step-by-step explanation:
-2x + y = -6
=> y = 2x - 6
-x + 3y = -6
=> -x + 3(2x - 6) = -6
=> -x + 6x - 18 = -6
=> 5x = 12
=> x = 12/5 or 2.4
-x + 3y = -6
=> - (2.4) + 3y = -6
=> 3y = -6 + 2.4
=> 3y = -3.6
=> y = - 1.2

if you want to make it easier for yourself you can turn them into whole numbers and here is how...
first find the common denominator for example for A it would be 12. then divide the denominators by 12
ex.
for the fraction -5/6 you would first divide 12 by 6 which is 2 and then multiply by numerator which is -5 so the answer woud be -10 and do the same thing for the other fractions and they will all be whole numbers so you dont have to deal with fractions.

The sum of the lengths of two opposite sides of the circumscribed quadrilateral is 12 cm, the length of a radius of the circle is 5 cm. Find the area of the quadrilateral
Answers
Answer:
60cm^2
Step-by-step explanation:
We assume that is a circumscribing quadrilateral, rather than one that is circumscribed. It is also called a "tangential quadrilateral" and its area is ...
K = sr
where s is the semi-perimeter, the sum of opposite sides, and r is the radius of the incircle.
K = (12 cm) (5cm) = 60 cm²
_____
A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.

Answer:
DB = 143 units
Step-by-step explanation:
In similar triangles, corresponding sides are always in the same ratio.
If ΔDCB ~ ΔDRS then:
\(\implies \sf DC : DR = CB : RS = DB : DS\)
From inspection of the given diagram:
DC = 91DR = 35DS = 55Therefore:
\(\implies \sf 91 : 35 =DB : 55\)
\(\implies \sf \dfrac{91}{35} =\dfrac{DB}{55}\)
\(\implies \sf 55 \cdot \dfrac{91}{35} =55 \cdot \dfrac{DB}{55}\)
\(\implies \sf 143=DB\)

please can someone explain how to get the time (t minutes) as well as a. and b. as i am baffled! i dont know what to do
Thankyouu!!
Answers
Step-by-step explanation:
To solve the problem, we'll use the information given to find the values of A and k in the equation T = 20 + Ae^(-kt), where T is the temperature in degrees Celsius at time t.
a. Finding the value of A:
We're given that the initial temperature of the tea was 70℃. Substituting this into the equation, we get:
70 = 20 + Ae^(0) (since e^0 = 1)
70 - 20 = A
A = 50
So the value of A is 50.
b. Finding the value of k:
We're told that it takes 4 minutes for the tea to decrease in temperature from 70℃ to 50℃. We can use this information to set up an equation and solve for k.
Substituting T = 70 and t = 4 into the equation, we have:
70 = 20 + 50e^(-4k)
Subtracting 20 from both sides:
50 = 50e^(-4k)
Dividing both sides by 50:
1 = e^(-4k)
Taking the natural logarithm (ln) of both sides:
ln(1) = ln(e^(-4k))
0 = -4k
Dividing both sides by -4:
0 = k
However, we need to check if this solution satisfies the condition for the tea to decrease in temperature from 70℃ to 50℃ in 4 minutes.
Substituting T = 50 and t = 4 into the equation, we have:
50 = 20 + 50e^(-4(0))
50 = 20 + 50e^0
50 = 20 + 50(1)
50 = 20 + 50
50 = 70
Since 50 is not equal to 70, the value of k = 0 does not satisfy the given condition.
Let's try another approach:
Substituting T = 50 and t = 4 into the equation, we have:
50 = 20 + 50e^(-4k)
Subtracting 20 from both sides:
30 = 50e^(-4k)
Dividing both sides by 50:
0.6 = e^(-4k)
Taking the natural logarithm (ln) of both sides:
ln(0.6) = ln(e^(-4k))
ln(0.6) = -4k ln(e)
ln(0.6) = -4k(1)
ln(0.6) = -4k
Simplifying further:
k = ln(0.6) / -4
Using a calculator or computer to evaluate ln(3/5) / -4, we get approximately:
k = ln(5/3) / 4
To recap:
a. The value of A is 50.
b. The value of k is approximately k = ln(5/3) / 4
.

Answers
Here, we are required bro determine how many worker Esther needs to employ to pick the same 600kg of onions in 3 hours as compared to 4 hours from last year.
This year, she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.
According to the data given, the total quantity of onions to be picked still remains 600 kg as from last year, only that she needs it done in 3 hours now.
Therefore,
Since 24 workers finished the work in 4 hours,This means that 96 workers are needed to finish the work in 1 hour( from 24×4 = 96).Therefore, since the work needs to be done in 3 hours this year, This means that it can be shared between X no. of workers.
Where X = 96/3= 32Therefore, this year she needs to employ 32 workers to pick a total of 600kg of onions in 3 hours.

Answers
The linear cost function is C(x) = 15x + 3250 and the cost function in marginal cost: $15; 150 items cost $5500 to produce is $ 5500 .
The linear operate is expressed as y = mx + b .....(1)A linear value operate expresses value as a linear operate of the amount of items;Let C(x) is that the total value, and x is that the range of things.
The slope "m" is named the cost and "b" is named the charge.
The value of m is $15 and the price of "x" is 150.
Total cost of 150 items are $5500
Substitute all the values within the equation (1) , we get
5500 = 15 (150) + b
5500 = 2250 + b
3250 = b
Hence , linear cost function is given by C(x) = 15x + 3250

How many total students are there?
If Sharon plans on taking Algebra 1 with Mr. Beachy, what is the empirical probability that she will receive an A?
If Cody plans on taking Algebra 1 with Mr. Beachy, what is the empirical probability that he will receive a B?
Answers
The empirical probability that Sharon will receive an A is 41/672, and the empirical probability that Cody will receive a B is 183/672.
To find the total number of students, we need to sum up the number of students in each grade category.
Total Students = Number of A students + Number of B students + Number of C students + Number of D students + Number of F students + Number of Incomplete students
Total Students = 41 + 183 + 265 + 96 + 85 + 2 = 672
Therefore, there are a total of 672 students.
To find the empirical probability that Sharon will receive an A, we need to divide the number of A students by the total number of students.
Empirical Probability of receiving an A = Number of A students / Total Students
Empirical Probability of receiving an A = 41 / 672
To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 1.
Empirical Probability of receiving an A = 41 / 672
To find the empirical probability that Cody will receive a B, we need to divide the number of B students by the total number of students.
Empirical Probability of receiving a B = Number of B students / Total Students
Empirical Probability of receiving a B = 183 / 672
Again, to simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 1.
Empirical Probability of receiving a B = 183 / 672
Therefore, the empirical probability that Sharon will receive an A is 41/672, and the empirical probability that Cody will receive a B is 183/672.

Terry earns a base salary of $2100 per month. Once he reaches $40000 in total sales, he earns an additional 5% commission (salary) on the amount of sales over $40000. Let s be the amount of his total sales for the month and M(s) be the amount of his salary for the month. (For instance, if he had sales of $42000 for the month, he would earn a salary of $2100 and 5% of $2000, since $42000 is $2000 more than $40000.)
Answers
Answer:
$4200Step-by-step explanation:
Step one:
given data
we are told that Terry's base salary is $2100 per month.
in addition 5% on sales greater than $40000.
let the monthly salary be M(s)
and let "s" be the amount of sales made
his monthly commission =0.05s
Step two:
The expression for his monthly earning is given as
M(s)=0.05s+2100 where s>40000
hence for a month when s=42000
M(s)=0.05(42000)+2100
M(s)=2100+2100
M(s)=4200
Therefore for an instance when s=42000 his earnings for the month will be $4200
Select all of the true statements for the following exponential function.
X: -1, 0, 1
Y: 1/3, 1/2, 3/4
f(x)= __ (__)^x+ ___
Answers
Answer:
Step-by-step explanation:
we can use the data points to write a system of equations to solve for the values of a and b in the general exponential function of the form f(x) = a(b)^x.
Using the data points, we get:
f(-1) = 1/3 = a(b)^(-1)
f(0) = 1/2 = a(b)^0 = a
f(1) = 3/4 = a(b)^1 = ab
Solving for a and b, we get:
a = 1/2
b = 3/4a = 3/4(1/2) = 3/8
Therefore, the exponential function that matches the given data points is:
f(x) = (3/8)^x + 1/2
Now we can evaluate the statements:
The base of the exponential function is 3/8. (True)
The function is decreasing. (False - since the base is between 0 and 1, the function is actually increasing)
The y-intercept of the function is (0, 1/2). (True)
The function passes through the point (2, 9/16). (False - the function is only defined for x = -1, 0, 1)
The function is concave up. (True)
