Answer:
5,4 km
Step-by-step explanation:
we know the area and the width.
the formula of the area of a parallelogram is
A = length x width
if we substitute the values that we know, we have
23,1 = x * 4,3
to find x we have to divide the two members by 4,3
x = 23,3/4,3 = 5,4 km
What is the solution to this system of equations? 4x + 5y = 7
3x – 2y =-12
The solution is
(-2, 3)
(3.-1)
(18. -9)
(13,-9)
Answer:
(-2, 3)
Step-by-step explanation:
4x + 5y = 7
3x - 2y = -12
Let's solve this by elimination. We want to eliminate one variable at a time. This means we need to multiply the equations to create a common multiple to cancel out a variable.
Let's work with y.
5y and -2y: For these values to cancel out, we need to multiply each term to create a common multiple.
2(4x + 5y = 7)
5(3x - 2y = -12)
Multiply.
8x + 10y = 14
15x - 10y = -60
Eliminate.
23x = -46
Divide both sides by 23.
x = -2
Now that we know x, let's plug it back into one of equations to find y.
4x + 5y = 7
4(-2) + 5y = 7
Multiply.
-8 + 5y = 7
Add.
5y = 15
Divide.
y = 3
Now we know x and y; let's plug both back into the equation we have not checked yet.
3x - 2y = -12
3(-2) - 2(3) = -12
Multiply.
-6 - 6 = -12
Subtract.
-12 = -12
Your solution is correct.
(-2, 3)

Austin's paycheck showed a regular weekly salary of $385.50, a deduction of $16.35, a commission of $28.75, and $37.35 for overtime. Which equation correctly finds Austin's final pay?
-$385.50 + $16.35 + (-$28.75) + (-$37.35) = - $435.25
$385.50 + $16.35 + (-$28.75) + (-$37.35) = $355.75
$385.50 + (-$16.35) + $28.75 + $37.35 = $435.25
$385.50 + (-$16.35) + $28.75 + $37.35 = -$467.95
Answer:
Answer option c is correct.
Step-by-step explanation:
385.50 is adding to the amount because it his paycheck. 16.35 is subtracted because it is bing deducted. Then there is the adding amount of 28.75 and 37.35 because of his commission and overtime. When you add it all up, you get 435.25. This whole thing would look like this in equation format:
385.50 +(-16.35) + 28.75 + 37.35 = 435.25.
What’s the last equation

Answer:
20 . . . . value of last equation
(A, B, C) = (4, 5, 10) or (3 1/3, 6, 12) . . . . values of symbols
Step-by-step explanation:
If we call the symbols, in order of appearance, A, B, C, then the equations are ...
2AB = 40 ⇒ AB = 20
2C/B = 4 ⇒ C/B = 2
Multiplying the second equation by the first, we get ...
(C/B)(AB) = AC = (2)(20) = 40 ⇒ AC = 40
Then the last equation is ...
(C-B)A = __
AC -AB = __ = 40 -20 = 20
The value of the last equation is 20.
_____
Per the above, we have AC = 40. The third equation is ...
(C +3A) = 22
Using the first relation, we have A = 40/C, so the second becomes ...
C +3(40/C) = 22
C² -22C +120 = 0
(C -10)(C -12) = 0
C = 10 or 12
As you can see, there are two possible solutions for the values of the symbols. The corresponding values of the other variables are ...
A = 40/C = 4 or 3 1/3
B = 20/A = C/2 = 5 or 6
The values of the variables are ...
(A, B, C) = (4, 5, 10) or (3 1/3, 6, 12)

Answer:
Should be 70 since <B is also 70
Step-by-step explanation:
Going by the diagram, you just read the value of x. The value of y requires a little bit of calculation. x=70 degree
Step-by-step explanation: Step One
Find x
You just read the value.
x is the same as the 70 degree angle. That comes about from parallel lines.
x = 70 degrees. <<<< answer
Step Two
Find y
All triangles have 180 degrees.
So ABC has 180 degrees.
70 + 50 + <ACB = 180 Combine like terms
120 + <ACB = 180 Subtract 120 from both sides
<ACB = 180 - 120
<ACB = 60
y = <ACB
y = 60 degrees. <<<< Answer.

A factory begun producing new parts. Data were collected on the
number of defective parts per 10,000 parts produced. The graph
shown displays some of the data for the first 10 weeks of production.
Write an equation that best models the data?
The equation that best models the data is 10x + y = 160 if the number of defective parts per 10,000 parts produced and points (10, 60) and (9, 70)
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
From the graph:
(10, 60) and (9, 70)
The line equation of best fit:
(y - 70) = (70-60)/(9-10)(x-9)
y - 70 = -10(x-9)
y - 70 = -10x + 90
10x + y = 160
Thus, the equation that best models the data is 10x + y = 160 if the number of defective parts per 10,000 parts produced and points (10, 60) and (9, 70)

The number of subscribers to a web service is growing exponentially. If there were 100,000 subscribers initially and it grows by 2.4% per month, how many subscribers will there be after a year? Round your answer to the nearest whole number of subscribers.
Answer:
280,000
Step-by-step explanation:
Solve
Given: 100,000 subscribers increases by 2.4% per month
To find: After a year, how much will that be?
First step:
Find the increase of the subscribers per month
100,000 of 2.4%
Set up an equation
2.4/100 × 100,000/1
Cross multiply, cancel zeros in both 100,000 and 100. Which is equal to:
2.4/1 x 1,000/1 =
2,400
Second step: If it increases per month,
then to find the year, find out how many months is in a year:
12 months = 1 year
Now that has been figured out, multiply the result by the result in the first step:
12 × 2400 = 28.800
Therefore, the number of subscribers will be after a year

In a class of students, the following data table summarizes how many students have a cat or a dog. What is the probability that a student chosen randomly from the class has a cat or a dog?
Has a cat Does not have a cat
Has a dog 9 2
Does not have a dog 4 5
Answer:
0 students have a cat and 92 students have a dog
The probability that a student is chosen randomly from the class has a cat or a dog is 15/20.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
The class has a cat and a dog = 9
Has a dog and does not have a cat = 2
Does not have a dog and has a cat = 4
Does not have dog and cat = 5
The total strength of the class is 20
The probability that a student is chosen randomly from the class has a cat or a dog = Number of favorable outcomes / total number of outcomes
P(E) = 15 /20
Hence, The probability that a student is chosen randomly from the class has a cat or a dog is 15/20.
