Problem 4
Draw a diagonal to connect the opposite non-right angles as shown below. This forms two right triangles. As you can probably guess, we'll use the pythagorean theorem to find the length of this segment. We'll call it x.
a^2+b^2 = c^2
7^2+24^2 = x^2
49+576 = x^2
x^2 = 625
x = sqrt(625)
x = 25
The hypotenuse of each right triangle is 25 units long.
Move your focus to the upper right triangle. We can use the pythagorean theorem again in a slightly different way to find y.
a^2+b^2 = c^2
15^2+y^2 = 25^2
225+y^2 = 625
y^2 = 625-225
y^2 = 400
y = sqrt(400)
y = 20
Answer: y = 20====================================================
Problem 6
The largest triangle, ignore segment x for now, is isosceles because we have two congruent sides.
As with any isosceles triangle, the vertex angle is bisected by the perpendicular bisector as shown in the diagram. This produces two identical right triangles. Most importantly, it means that horizontal side 4 is cut in half to 4/2 = 2 units.
In short, each smaller right triangle has a horizontal leg of 2, vertical leg x, and hypotenuse 6. Let's focus on just one of those right triangles.
Like the previous problem, we'll use the pythagorean theorem to find x.
a^2+b^2 = c^2
x^2+2^2 = 6^2
x^2+4 = 36
x^2 = 36-4
x^2 = 32
x = sqrt(32)
x = sqrt(16*2)
x = sqrt(16)*sqrt(2)
x = 4*sqrt(2)
Answer: x = 4*sqrt(2)Related Questions

A wholesaler sold an electric item to a retailer at 20 % profit. The retailer sold it at Rs.2052 to a customer at 5% loss.
i) How much did the retailer pay for it?
ii) How much did the wholesaler pay for it?
pls on full process
will mark as a brainlist
Answers
Answer:
i) 2160
ii) 1800
Step-by-step explanation:
so, the retailer sold the item for 2052, if I understand the problem description correctly.
and with this sale price, he actually made a loss of 5%.
so, 2052 are actually only 95% of what he himself paid the wholesaler for it.
2052 = 95%
1% = 2052/95 = 21.60
100% (the whole price the retailer paid to the wholesaler) = 21.60 × 100 = 2160
so, now, these 2160 have the wholesaler a profit from his perspective of 20%.
that means this price includes the 20% profit margin.
2160 = 120%
1% = 2160 / 120 = 18
100% (the price the wholesaler originally paid) = 18 × 100 = 1800

Please help me i need the answer right now. The lesson is Rational Root Theorem.
Answers
Step-by-step explanation:
1. The length is one more thrice it's width. The height is 4 more than it width. We can represent the
x+4.(3x+1)(x)The volume is 720.Volume of Rectangular prism is LxWXH. So the volume is equal to the terms all multiplied. which is[tex](3x + 1)(x + 4)[/tex]
[tex](3 {x}^{2} + 13x + 4)x = 720[/tex]
Multiply it by x.
[tex]3 {x}^{3} + 13 {x}^{2} + 4x = 720[/tex]
[tex] 3{x}^{3} + 13 {x}^{2} + 4 x - 720[/tex]
The possible roots
The possible roots are plus or minus is1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, and 720. By a long list of substitution, 5 is a root. So this means that x=5. So the width has to be
[tex]x = 5[/tex]
2. First. we apply the Rational Root Theorem so the possible roots are plus or minus 1,2,3,6.
Let check via synethic division to see which are roots.
Let try 1 and -1 first. If we plug 1 into the equation, we get
[tex]1 - 2 - 5 + 6 = 0[/tex]
So 1 or (x-1) is a solution. Since it's a solution we can divide this into our original polynomial to get us a new polynomial that is more simplified. If we apply synthetic division, we get a new polynomial in
[tex] {x}^{2} - x - 6[/tex]
We can then factor this into
[tex](x - 3)(x + 2)[/tex]
So our roots or factors is
[tex](x - 1)(x - 3)(x + 2)[/tex]

Halla el conjunto solución del siguiente sistema de ecuaciones aplicando el método de reducción: 2x + 3y = 8 x – 5y = 6
Answers
Answer:
x = 7.535 and y = 0.307
Step-by-step explanation:
Given that,
Two equations,
2x + 3y = 8 ...(1)
x – 5y = 6....(2)
Multiply equation (2) by -2.
-2x + 10y = -12....(3)
Now, adding equations (1) and (2),
2x + 3y -2x + 10y = 8-12
13y = 4
y = 0.307
Put the value of y in equation (2).
x – 5(0.307) = 6
x = 6 + 1.535
x = 7.535
So, the solutions of the given equation are x = 7.535 and y = 0.307.

Victor had dozen boxes with n number of water bottles in each box.After removing dozen bottles, there were 84 bottles.Find the number of bottles in each box.
Answers
Answer:
There are 8 bottles in each box.
Step-by-step explanation:
Victor has 12 boxes with 'n' number of water bottles in each box.
A dozen is same as 12.
Now, 12 boxes and each with 'n' number of bottles. Total number of bottles in '12' boxes is 12n bottles.
Now, it is removing 12(a dozen) bottles from 12n bottles which gives 84.
So, 12n -12=84
Add both sides 12
12n= 96
Divide both sides by 12
n=8
So, there are 8 bottles in each box.

Answers
Answer:
Step-by-step explanation:
Patrick thinks that when 'a' is a negative integer and 'b' is a positive,
Let "a = -2" and "b = 3"
a). a - b is positive.
a - b = -2 - 3
= -5 {negative]
Therefore, statement is False.
(a - b) is negative.
b). b - a is positive.
b - a = 3 - (-2)
= 3 + 2
= 5 [Positive]
Statement is True.
c). a - (-b) is negative.
a - (-b) = a + b
= -2 + 3
= 1 [Positive]
False.
But it's true when a = -5 and b = 3
a - (-b) = -5 - 3
= -8 [Negative]

The values of x between which the relative maximum occurs is between the x-values; -1 and 1

The table of the partial set of the polynomial values is presented as follows;
[tex]\begin{array}{rcr}\mathbf{x}&&\mathbf{g(x)}\\-2&&-14\\-1&&-2\\0&&0\\1&&-4\\2&&-6\\3&&2\end{array}[/tex]
From the table above, we have that g(x) is maximum (g(x) = 2) when x = 3
Method;
Define and find the relative maximum
The relative maximum of a function, is given by a point where the graph of the function changes direction from 'continuously' increasing values of the function before the point to 'continuously' decreasing values of the function after the point
From the table, at x = -2, -1, 0, g(x) = -14, -2, 0, and is therefore, increasing
Where, x = 0, 1, 2, we have g(x) = 0, -4, -6, therefore, g(x) is decreasing
The maximum value of g(x), in the region where g(x) changes from increasing to decreasing is g(x) = 0, which is given between the x-values of -1 and 1
Therefore, the relative maximum is most likely to occur between the values of x = -1, and x = 1, which is the option -1 and 1

Angle ECD and Angle FDC are same-side interior angles. They lie on the same side of the transversal and are on the inside of the two parallel lines. Same-side interior angles are supplementary, meaning that they add up to 180.
(40x + 15) + (5x + 30) = 180
45x + 45 = 180
45x = 135
x = 3
Angle ECD = 40(3) + 15 = 120 + 15 = 135
Angle FDC = 5(3) + 30 = 15 + 30 = 45

Calculate expression value : G = 2x^3 + 35x^2 + 15x + 1 with x = -17
Answers
Not sure if this is correct the question was a little confusing
G = -20195
Step-by-step explanation:
G = 2x^3 + 35x^2 + 15x + 1 where x = -17
Substitute all the x’s for -17!
G = 2(-17)^3 + 35(-17)^2 + 15(-17) + 1
Solve for the exponents first!
G = 2(-4913) + 35(-289) + 15(-17) + 1
Multiply
G = -9826 + -10115 + -255 + 1
Add -9826 + -10115
G = -19941 + -255 + 1
Add -19941 + -255
G = -20196 + 1
Add -20196 + 1
G = -20195

A cook has 4 cups of raisins to make oatmeal cookies. The recipe requires 3 cup of raisins for each
batch of cookies. How many batches of cookies can the cook make?
Answers
Answer: 1⅓ batch of cookies
Step-by-step explanation:
From the question, we are given the information that a cook has 4 cups of raisins to make oatmeal cookies and that the recipe requires 3 cup of raisins for each batch of cookies.
Therefore, the number of batches of cookies that the cook can make will be the number of cups of rasins that the cook has divided by the number of reasons needed for each cookie. This will then be:
= 4/3
= 1⅓ batch of cookies
