Answer:
Step-by-step explanation:
First, look at your terms. You have two terms and two variables in each. So they can be factored out because you can distribute them back in easily.
Focus one variable first, x. You cant factor an x^12 out of an x^4. You can, but you really don't want to, it'll turn your problem into a mess. So the only thing you can do is factor out the lower exponent, x^4.
[tex]x^4(x^8y^4-y^1^2)[/tex]
We arent done yet because the terms still share the y variable. You cant factor a y^12 from a y^4. This is the same problem with the x variable. So take out the lower one, y^4.
[tex]x^4y^4(x^8-y^8)[/tex]
Rochelle is competing in a marathon. She knows that once she runs 14.7 km she will have completed 35% of the marathon
Given :
Rochelle is competing in a marathon.
She knows that once she runs 14.7 km she will have completed 35% of the marathon.
To Find :
Total length of the marathon.
Solution :
Let, total distance of the marathon is x km.
So, 35% of x is 14.7 .
In mathematics :
[tex]14.7 = x\times \dfrac{35}{100}\\\\x = \dfrac{14.7\times 100}{35}\\\\x = 42\ km[/tex]
Therefore, total length of the marathon is 42 km.

Jana earns $25 per week for mowing the lawn and deposits the money into her savings account. The amount of money in Jana's account can be
represented by the equation y = 25x + 125, where x is the number of weeks she has been mowing the lawn. What does the y-intercept of the graph
represent in this situation?
Hi there! x would be 6 weeks..
Explanation:
So here says that Jana earns $25 per week for mowing the lawn. But in “x” weeks, she earns $125...this means that you would have to divide 125 with 25 or 25 multiply by x to find the answer of x.
How much does 25 go to 100? Well it would be 5. So for $100 it would be 5 weeks. We also know that 25 is 1 week. So add 5 with 1. 5 plus 1 would be 6.
Therefore, for $125, Jana would have to work for 6 whole weeks.
Find the smaller of 2 consecutive integers, x, if the sum of the smaller and 4 times the larger is 44.
Answer:
8
Step-by-step explanation:
Find the smaller of 2 consecutive integers, x, if the sum of the smaller and 4 times the larger is 44.
Two consecutive integers are represented as:
Smaller integer = x ,
Larger Integer = x + 1
If the sum of the smaller and 4 times the larger is 44
x + 4(x + 1) = 44
x + 4x + 4 = 44
5x + 4 = 44
5x = 44 - 4
5x = 40
x = 40/5
x = 8
Therefore, the smaller of 2 consecutive integers which is x = 8
sarita's father's age is 49 years his age is 4 years more than three times Sarita age find the present age of Sarita
Answer:
15years
Step-by-step explanation:
Let the present age of sarita be x
Sarita father age = 49years
If his father age is 4 years more than three times Sarita age, this is expressed as;
49 = 3x + 4
Sind x
3x = 49-4
3x = 45
x = 45/3
x = 15
hence present age of sarita is 15years

Find the degree of the monomial.
5b^7c^6
Answer: 13
Explanation: To find the degree of a monomial, we need to take
the sum of the exponents of all the variables in the monomial.
So the degree of this monomial is 7 + 6 or 13.
So the degree of this monomial is 13.

Answer:
The cosine of A is equal to [tex]\frac{3\sqrt{58}}{58}\\[/tex]
Step-by-step explanation:
Cosine is is calculated as adjacent over hypotenuse. The line adjacent to A is 3 in length.
So we can say that the cosine is equal to 3/√58, but need to multiply it by √58 / √58 to ensure we have a non-radical denominator
[tex]A = \frac{3}{\sqrt{58}}\\A = \frac{3\sqrt{58}}{58}\\[/tex]

The measure of an exterior angle of a triangle is 40°. What is the sum of the measures of the corresponding remote interior angles?
Answer:
40 degrees
Step-by-step explanation:
Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40.
If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40°.
What are Triangle theories?A triangle is the smallest polygon with three sides and three interior angles.Theorem 1: The Sum of Angles property of a triangle states that the sum of the interior angles of a triangle is 180°.Theorem 2: If you lengthen one side of a triangle, the resulting exterior angle is the sum of the two opposite interior angles of the triangle.A exterior angle equals the sum of his two other angles in the triangle, so the sum of the angles in the triangle is 180 degrees. In other words, the other two angles of the triangle (which together make up the exterior angle) must be combined with the third angle to make a 180 degree angle.40 degrees is the sum of the measures of the corresponding remote interior angles.
Because there are 180 interior angles in a triangle, you need one of the sides. If an angle's exterior is 40 degrees, we know that the interior angle is 140 degrees. This means that the sum of the other interior angles have to be 40 as 180-140 is 40°.

Cameras R Us has a sale for 25% off camera bags, which is a discount of $20. To find the original cost of the camera bag, Tara creates the following diagram.
A 2-column table with 6 rows. Column 1 has entries 20 percent, 20 percent, 20 percent, 20 percent, 20 percent, Total 100 percent. Column 2 has entries 25 dollars, 25 dollars, 25 dollars, 25 dollars, 25 dollars, blank total.
What errors did Tara make in her diagram? Check all that apply.
There should be 5 rows labeled 20%.
The 25 should be for each percent, not dollar amounts.
The percents do not add up to a whole of 100%.
There should be 4 columns of 25% that each equal $20.

Step-by-step explanation:
We are given that

y=Length of garden
According to question
[tex]x\geq 5[/tex]
[tex]y\geq 20[/tex]
Perimeter of rectangle=[tex]2(x+y)[/tex]
Where x=Width of rectangle
y=Length of rectangle
Fencing used =[tex]2(x+y)[/tex]
[tex]2(x+y)\leq 80[/tex]
First we change inequality into equality
[tex]x=5[/tex]...(1)
[tex]y=20[/tex]...(2)
[tex]2(x+y)=80[/tex]
[tex]x+y=40[/tex]...(3)
Substitute x=0 in equation (3)
[tex]y=40[/tex]
Substitute y=0 in equation (3)
[tex]x=40[/tex]
Substitute x=0 and y=0 in equation (3)
[tex]2(x+y)\leq 80[/tex]
[tex]0\leq 80[/tex]
It is true. Therefore, the shaded region below the line.
[tex]0\geq 5[/tex]
[tex]0\geq 20[/tex]
These are false equation .Therefore, the shaded region above the line.
Substitute x=5 in equation (3)
[tex]5+y=40[/tex]
[tex]y=40-5=35[/tex]
Substitute y=20 in equation (3)
[tex]x+20=40[/tex]
[tex]x=40-20=20[/tex]
Intersection point of equation (1) and (3) is (5,35) and intersect point of equation (2) and (3) is (20,20).
Now,
a.(10,23)
Substitute in
[tex]2(x+y)\leq 80[/tex]
[tex]2(10+23)\leq 80[/tex]
[tex]66\geq 80[/tex]

it satisfied all inequality.
Hence, it is a solution.
c.(18,25)

[tex]2(18+25)=86>80[/tex]
It does not satisfied third inequality
Hence, it is not a solution.

35>20
[tex]2(8+35)=86>80[/tex]
It does not satisfied third inequality
Hence, it is not a solution.

The diagonals of a rectangle have length 12 and intersect in a 40 degree angle. Find the length and width rounded to the nearest tenth.
Answer:
Length is 7.7 and width is 9.2
Step-by-step explanation:
The length and width of the rectangle will be the y and x coordinate of the diagonal line at angle of 40 degrees
Length L = dsin theta
Width W = d coos theta
d is the length of the diagonal
Given
d = 12
theta = 40°
Substitute
Length = 12sin40°
Length = 12(0.6428)
Length = 7.7135
Length ≈ 7.7
Width = 12cos 40
Width = 12(0.7660)
Width = 9.192
Width = 9.2
Hence the length is 7.7 and width is 9.2
