Estimate the solution of the system x+y=4 2x-y=6 by sketching a graph of each linear function. Then solve the system algebraically. Use your estimate to judge the reasonableness of your solution. The estimated solution is The algebraic solution is The solution is/is not reasonable because
Answer:
(10/3, 2/3)
Step-by-step explanation:
You may find it easier to write these two equations x+y=4 2x-y=6 in a column:
x+y=4
2x-y=6
Adding these together will eliminate y:
3x = 10. Then x = 10/3.
Substituting 10/3 for x in the first equation results in:
10/3 + y = 4
Clear fractions by multiplying all three terms by 3:
10 + 3y = 12
Then 3y = 2, and y = 2/3.
The solution is (10/3, 2/3)
Hi!! Please explain how you got the answer, thanks!! :))
Start out by finding the area of the square.
a = 4²
a = 16
Since all we have to look at is 1/4 of this square, multiply the area by 1/4.
(16)1/4
4
The area of the triangle is 4.
Now we need the area of the circle.
a = πr²
Sub: a = π(2)²
a = π(4)
Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.
a = 4 - 1/4(π(4))
a = 4 - 1/4π x 1
a = 4 - 1/4π
Now this is where it's supposed to go, considering the fact that π isn't given a value.
Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.
Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.
Uhh good luck I guess this math test is weird

Which fractions are equivalent to the fraction below check all that apply 12/21 ?
find the perimeter of these figures *
please*
Answer:
The perimeter of figure a is 44 inches, the perimeter of figure b is 72 inches.
Step-by-step explanation:
The sides of figure a is 8; 2; 3; 12; 2; 12; 3; 2, to get the perimeter, add all the sides together, which will be 8 + 2 * 2 + 3 * 2 + 12 * 2 = 8 + 4 + 6 + 24 = 12 + 30 = 42 inches. The sides of figure b is 3; 3; 3; 3; 13; 13; 5; 5; 5; 5; 7; 7, to get the perimeter, add all the sides together, which will be 3 * 4 + 13 * 2 + 5 * 4 + 7 * 2 = 12 + 26 + 20 + 14 = 32 + 40 = 72 inches.
Answer:
a) 44
2 + 8 + 2 + 8 + 12 + 12 = 44
b) 72
13 + 13 + 3 +3 +3 +3 +5 +5 +5 +5 +7 +7 = 72
Step-by-step explanation:
Can some one explain how to do it please. I am so confused.
Hi there!
Your job, at least on this triangle, is pretty simple. This is a 45-45-90 triangle.
Because this is a 45-45-90 triangle, both legs are 5. That leaves us to find the hypotenuse, x.
And a 45-45-90 triangle's hypotenuse is easy. You just take the measure of one of the legs, or 5 in this case, and stick a [tex]\sqrt{2\\}[/tex] right next to it. So your answer will be:
[tex]5\sqrt{2}[/tex]
I hope this helps! :)
if the side of a traingular fiels is in ratio of 6:9:10. if it perimeter is 2500m what is the area of that field
Answer:
266634.11 m^2
Step-by-step explanation:
The following information is given in the question
The ratio of the side of the triangular fields is 6:9:10
And, the perimeter is 2500m
We need to find the area of that field
So
Let us assume the 3 sides be x
Here so the sides be 6x,9x, 10x
Now the perimeter = sum of the length of all sides
2500 = 6x + 9x + 10x
2500 = 25x
x = 100
The three sides would be 600,900 and 1000
Now the area of that field would be
As we know that
The Area of the triangle as per the Heron Formula is
[tex]= \sqrt{s(s-a)(s-b)(s-c)} \\\\= \sqrt{1250(1250-600)(1250-900)(1250-1000)} \\\\= \sqrt{1250(650)(350)(250)} \\\\= \sqrt{71093750000}[/tex]
= 266634.11 m^2

Step-by-step explanation:
According to the 2010 census, 11.7% of the people in the state of Oregon were Hispanic or Latino. A political party wants to know how much impact the Hispanic and Latino vote will have, so they wonder if that percentage has changed since then. They take a random sample of 853 adults in Oregon and ask, among other things, their race. 113 of the people surveyed were Hispanic or Latino. Can the political party conclude that the Hispanic proportion of the population has changed since 2010? Test an appropriate hypothesis.
Answer:

6 plates and 5 cups cost 32.10 dollars. 7 plates and 6 cups cost 37.70 dollars. Each plate costs the same amount as the other plates, and each cup costs the same amount as the other cups. What is the cost of 1 plate? What is the cost of 1 cup?
Answer:
Plates are 2.80 Dollars and cups are 1.40 dollars
Step-by-step explanation:
Cups = c
Plates = p
6p + 5c = 23.80 ==> multiply by 6 ==> 36p + 30c = 142.80
7p + 6c = 28.00 ==> multiply by 5 ==> 35p + 30c = 140.00
Now use algebra to have the 30c be on one side and the rest on the other:
36p + 30c = 142.80 | -36p
30c = 142.80 - 36p
35p + 30c = 140.00 | -35p
30c = 140.00 - 35p
Now set them equal to each other about the 30c:
142.80 - 36p = 140.00 - 35p
Use algebra to solve for p:
142.80 - 36p = 140.00 - 35p | +36p
142.80 = 140.00 + p | - 140
2.80 = p
Go back to one of the "30c" equations and plug in the value for p:
30c = 140 - 35p
30c = 140 - 35(2.80)
30c = 140 - 98
30c = 42 | /30
c = 42/30
c = 1.4
Answer:
the cost of 1 plate $4.1
the cost of 1 cup $1.5
Step-by-step explanation:
6p + 5c = 32.10
7p + 6c= 37.70
Multiply the first by 6
Multiply the second by -5
and then ADD both
36p +30c = 192.6
-35p-30c = -188.5 (30c is cancelled)
p = 4.1
4.1(6) +5c = 32.10
24.6 +5c = 32.10
5c = 7.5
c= 1.5
1.5(5) =7.5
24.6 + 7.5 = 32.10
0.38x < 25 -10.81 - 10
Answer:

Answer: 7^3/7^6= 1/343
Step-by-step explanation: We move 7^-6 to a denominator because we cannot have a negative exponent in the numerator.
So it would be 7^3/7^6
Which then would be 7*7*7/7*7*7*7*7*7
Which would equal 343/117649
Simplify and you get 1/343

Select the correct answer. Which expression is a prime polynomial?
A. x^3 - 27y^6
B. x^4 + 20x^2 - 100
C. 3x^2 +18y
D. 10x^4 - 5x^3 + 70x^2 +3x
The expression is a prime polynomial is [tex]x^3 - 27y^6[/tex]
What is a prime polynomial?An irreducible polynomial is a polynomial (of degree greater than zero) that cannot be factored into polynomials of lower degrees. The irreducibility property depends on the nature of the coefficients that are accepted for the possible factors, that is, the field or ring to which the coefficients of the polynomial and its possible factors should belong.
In this way we have that:
[tex]x^3 - 27y^6[/tex]

The following mistakes could be explained observed from the plotted bar chart presented in the attachment :
1.) The numeric label of the y-axis which shows the number of text messages isn't well scaled, the numbering did not start from 0, hence this is a defect in the scaling of the bar chart.
2.) Looking closely, the plotted bars do not ALIGN well in terms of spacing as the interval between each bar isn't consistent.
3.) Both the x and y axis of the graph are t labeled thus failing to add a good and meaningful description to the plot especially for first time viewers.
