Answer:
868.3%
Step-by-step explanation:
8.683 x 100 = 868.3%
Answer: 868.3%
All you need to do to convert a decimal to a percentage is multiply by 100. In this case we have to multiply 8.683 by 100 which gives us 868.3%
In the figure below, a circle is inscribed in a
square that has side length 8 units. Express the
shaded area of the figure in terms of T.
9514 1404 393
Answer:
64 -16π square units
Step-by-step explanation:
The area of the square is ...
A = (8 units)^2 = 64 units^2
The area of the circle is ...
A = πr^2 = π(4 units)^2 = 16π units^2
The shaded area is the difference:
shaded area = (64 -16π) units^2.

Solve the following system.
y = -2x^2 + 3x - 1 and x + y = -1.
The solutions are
and
Given:
The equations of a system of equations are
[tex]y=-2x^2+3x-1[/tex]
[tex]x+y=-1[/tex]
To find:
The solution of the given system of equations.
Solution:
We have,
[tex]y=-2x^2+3x-1[/tex] ...(i)
[tex]x+y=-1[/tex] ...(ii)
Using (i) and (ii), we get
[tex]x+(-2x^2+3x-1)=-1[/tex]
[tex]x-2x^2+3x-1+1=0[/tex]
[tex]-2x^2+4x=0[/tex]
Taking out the common factors.
[tex]2x(-x+2)=0[/tex]
Using zero product property,we get
[tex]2x=0[/tex] and [tex]-x+2=0[/tex]
[tex]x=0[/tex] and [tex]2=x[/tex]
For x=0, we have
[tex]0+y=-1[/tex]
[tex]y=-1[/tex]
For x=2, we have
[tex]2+y=-1[/tex]
[tex]y=-1-2[/tex]
[tex]y=-3[/tex]
Therefore, the two solutions of the given system of equations are (0,-1) and (2,-3).

Kate writes an algebraic expression using each of the variables x and y only once. they first expression she writes uses x and y as factors. Than she writes another expression that uses x and y as terms. if x and y are both negative integers, write a comparison between the two expressions
Choice A: More information is needed.
Choice B: Using x and y factor results in an expression of greater value than using x and y as terms.
Choice C: None of the other answers are correct.
Choice D: The two expressions are of equal value.
Answer:
B: Using x and y factor results in an expression of greater value than using x and y as terms.
Step-by-step explanation:
For her first expression, x and y are factors;
xy
For her second expression, x and y are written as terms;
x + y
For x and y are both negative integers, then;
-x * -y = xy ............... 1
-x + (-y) = - x - y
= - (x + y) .............. 2
Therefore, the value of x and y factors is greater than that when x and y are as terms. Thus the correct option is B.
Which of the following rational functions is graphed below?
Answer:
B
Step-by-step explanation:
The function's zeroes results in vertical asymptotes. As one is at x = 1 and the other at x = -2, the zeroes must be (x-1) and (x+2), which only B contains in the numerator.
Akayo claims that there are centers of dialstiond through ehich a dialation of line n by a factor of 1.5 leaves line n unchanged
Answer:
See Explanation
Step-by-step explanation:
This question requires further details. In absence of the details, I will answer on a general term.
When a line is dilated (whether expanded or compressed), the new line will be on the same line with the dilated line; however, the length of both lines will be different
Take for instance:
Line AB of coordinate (1,3) is horizontally dilated by 2,
Horizontal dilation rule is: y = f(cx) where c is the dilation factor
So, the new point will be
A'B' = (1, 3 * 2)
A'B' = (1,6)
When you compare the x coordinate of both line, you will observe that they have the same x coordinate of 1.
This implies that they are on the same level but different length
The same is applicable to vertical dilation
the new point will be:

Figure 2 of a tile pattern has 8 tiles, while figure 5 has 14 tiles. If the tile pattern grows at a constant rate, how many tiles will figure 40 have?
Answer:
84 tiles
Step-by-step explanation:
Given that :
Figure 2 = 8 tiles
Figure 5 = 14 tiles
Growth rate :
(Figure 5 - figure 2)x= 14 - 8
3x = 6
x = 6/3
x = 2
(Figure 40 - figure 2) = 38 * x
Initial number of tiles + 38x
8 + 38(2)
8 + 76
= 84
Figure 40 = 84 tiles
Angharad is buying a new 50-inch screen TV (remember that TV screens are measured along the diagonal )
a) If it is 30 inches tall, how wide is the screen ?
b) Her TV cabinet is 30 inches wide .will the TV fit inside it ?
Answer:
a) 40 inches
b) No it will not fit inside
Step-by-step explanation:
Angharad is buying a new 50-inch screen TV (remember that TV screens are measured along the diagonal )
a) If it is 30 inches tall, how wide is the screen ?
Diagonal ² = Width² + Height²
Diagonal = 50 inches
Height = 30 inches
50² = Width² + 30²
Width² = 50² - 30²
Width = √50² - 30²
Width = √(1600)
Width = 40 inches
b) Her TV cabinet is 30 inches wide .will the TV fit inside it ?
No it will not fit inside
This is because, the width of the TV is the above calculation is 40 inches. This is wider than the width of the TV cabinet, hence, it won't fit inside

Answer:
35
Step-by-step explanation:
Since you know that a triangle must have a total of 180 degrees and a right triangle is 90 degrees then you just subtract 90 from 180 and you get 90. Then subtract 55 from 90 and you get 35 which is the only possible answer.
Remy was on vacation in New France, Canada. He went to the Ratatouille restaurant and had an excellent dinner. How much did
he pay if the dinner cost $32 and he gave a 18% tip? How much was the tip?
Answer:
See both answers in the explanation
Step-by-step explanation:
Given data
Cost of dinner= $32
TIp=18%
Let us find the amount of the tip
=18/100*32
=0.18*32
=$5.76
Hence the total amount paid is
=5.76+32
=$37.76
The Tip is
=$5.76
The sum of the measures of angle A, angle B, and angle C is 180 degrees. The measure of angle C
is five times the measure of angle A. The measure of angle B is 40 degrees more than the
measure of angle A.

Write the word sentence as an equation. Then solve the equation. A number $k$ increased by 7 is 34. An equation that represents this word sentence is . The solution is $k=$ .
Answer: k = 27
Step-by-step explanation:
Here's the complete question:
Write the word sentence as an equation. Then solve the equation. A number k increased by 7 is 34.
An increase in k simply means that there's an addition. This will be:
k + 7 = 34
k = 34 - 7
k = 27
Therefore, the value of k is 27

Parallel to 7x+8y=-40 and goes through (16, -12)
Answer:
7x + 8y = 16
Step-by-step explanation:
You need to get the slope of the given line.
The line is in standard form ax + by = c
The slope = -a/b. (That's a little formula you can use to find the slope when the line is in standard form)
In this problem, m = - 7/8
Since the line we are trying to find is parallel, it has a slope of -7/8
Now use the point-slope form
y - (-12) = -7/8(x - 16) Multiply thru by 8 to remove the fractions
8(y + 12) = -7(x - 16)
8y + 96 = - 7x + 112
7x + 8y = 16
