Answer:
8
Step-by-step explanation:
Given the expression
4t^6-r^10 we are to factorize in the form;
(2t^x+r^y)(2t^x-r^y)
First we need to factorize (2t^x+r^y)(2t^x-r^y)
[tex]= (2t^x+r^y)(2t^x-r^y)\\= 4t^{2x}-2t^xr^y + 2t^xr^y - r^{2y}\\= 4t^{2x}-r^{2y}[/tex]
Compare [tex]4t^{2x}-r^{2y} \ with \ 4t^6-r^{10}[/tex]
[tex]4t^{2x} = 4t^6\\t^{2x} = t^6\\equate \ the \ powers\\2x = 6\\x = 3\\[/tex]
Get y;
[tex]r^{2y} = r^{10}\\2y = 10\\y = 5\\Hence \ x + y = 3+5 = 8[/tex]
Hence the sum of x and y is 8

Answer:
73,58,107,49,131
Step-by-step explanation:
m∠1=73°because alternate interior angles
m∠2= 180-49-73=58° because straight lines make 180° angles
m∠3=58+49=107° because alternate interior angles
m∠4 =49° because alternate interior angles
m∠5=180-49=131° because straight lines make 180° angles

The sum of 9/26 and -4/13 is ____
Answer:
1/26
Step-by-step explanation:
-4/13 is equivalent to -8/26. Since 9/26 and -8/26 have the same denominator, you can add together the numerator to get the numerator of the final answer. 9-8 is 1, so your answer is 1/26.

Citrus farmer who grows mandarin oranges finds that the diameters of mandarin oranges harvested on his farm follow a normal distribution with a mean diameter of 5.85 cm and a standard deviation of 0.24 cm. Find the 80th percentile for the diameters of mandarin oranges, round 4 decimal places
Answer:
6.0520
Step-by-step explanation:
Given that:
Mean = 5.85
Standard deviation = 0.24
Let N denote the 80th percentile.
P(X < N) = 0.8
[tex]P(Z < \dfrac{(N - 5.85)}{0.24}) = 0.8[/tex]
Using the Excel formula: = NORM.INV(0.8,5.85,0.24)
The 80th percentile for the diameters of mandarin oranges:
= 6.0520 (to 4 decimal place)

27 is 75% of what number ?
THE ANSWER IS
?????
36
Answer:
27 is 75% of 36Step-by-step explanation:
METHOD 1:
[tex]\begin{array}{ccc}27&-&75\%\\\\x&-&100\%\end{array}\qquad|\text{cross multiply}[/tex]
[tex](75)(x)=(27)(100)\\\\75x=2700\qquad|\text{divide both sides by 75}\\\\x=36[/tex]
METHOD 2:
[tex]n[/tex]-a number
[tex]p\%=\dfrac{p}{100}\\\\75\%=\dfrac{75}{100}=0.75[/tex]
75% of a number is 27:
[tex]0.75\cdot n=27\qquad|\text{divide both sides by 0.75}\\\\n=36[/tex]
2.) What is the y- coordinate for the SOLUTION to the following system of
equations? (Note: although you do not HAVE to graph, it is suggested.)
y = -x- 2
by = 4(x - 1) + 7
Answer:
y-coordinate for the SOLUTION to the following system of
equations will be:
y=-1The graph is also attached.
Step-by-step explanation:
Given the system of equations
[tex]y\:=\:-x-\:2[/tex]
[tex]y\:=\:4\left(x\:-\:1\right)\:+\:7[/tex]
Let us solve the system of equations to determine the y- coordinate
[tex]\begin{bmatrix}y=-x-2\\ y=4\left(x-1\right)+7\end{bmatrix}[/tex]
[tex]y-4x=3[/tex]
[tex]-[/tex]
[tex]\underline{y+x=-2}[/tex]
[tex]-5x=5[/tex]
so
[tex]\begin{bmatrix}y+x=-2\\ -5x=5\end{bmatrix}[/tex]
solve -5x=5 for x
[tex]-5x=5[/tex]
Divide both sides by -5
[tex]\frac{-5x}{-5}=\frac{5}{-5}[/tex]
[tex]x=-1[/tex]
[tex]\mathrm{For\:}y+x=-2\mathrm{\:plug\:in\:}x=-1[/tex]
[tex]y-1=-2[/tex]
Add 1 to both sides
[tex]y-1+1=-2+1[/tex]
[tex]y=-1[/tex]
Thus, y-coordinate for the SOLUTION to the following system of
equations will be:
y=-1The graph is also attached.

Choose the similarity statement that best represents the triangles. Provide evidence.
A. Triangles are similar by AA similarity.
B. Triangle are similar by SAS similarity.
C. Triangles are similar by SSS similarity.
D. Triangles are not similar.
Answer:
D.Triangles are not similar
Answer:
The best option would be c
Step-by-step explanation:
C
because the ration of all the three respective sides are similar as follows:
3/2 = 1.5
4.5/3 = 1.5
6/4 = 1.5
so basically the second triangle is just 1.5 times bigger than the first triangle and since ratio of all the three sides are similar SSS should be the similarity.

Zach bought 8 pieces of bubble gum that were $0.20 each. He used a number line to find the total cost. Choose the numbers to complete the sentences.
Zach started on the number line at 0.2 for the cost of one piece of gum. He moved
_____
hash marks. The total cost is
_____
Answer:
He moved 7 hash marks and the product is $1.60
Step-by-step explanation:
It’s says he starts at 0.2 on the number line, so that’s the second hash mark after the 0. If you move to the right on each hash all the way til the 2, you moved 7 times.
The product of 8 x .20 = 1.60
Zach started on the number line at 0.2 for the cost of one piece of gum he moved 1.4 hash marks and the total cost is 1.6 dollars.
What is a number line?A number line is a horizontal one-dimensional line where we can plot any real number called the real number line. The origin of a real number line is denoted with a value of zero.
Zach bought 8 pieces of bubble gum that were 0.2 dollars each.
If we assume x as the no. of pieces then this can be represented as,
0.2x, where x ∈ N, [1, 8].
Zach started on the no. line at 0.2 for the cost of one piece of bubble gum.
∴ The cost of 8 pieces of bubble gum is (0.2×8) = 1.6 dollars.
So, he moved (1.6 - 0.2) = 1.4 on the number line.
