Answer:
12.88
Step-by-step explanation:
First you do 20×.30 and get 6 so you subtract 20-6 which equals 14. Then you do 14×.08 and get 1.12 and you subtract that from 14. and you'll get 12.88

Determine whether the graphs of the given equations are parallel, perpendicular, or neither.
Y= -2x+3
2x+y=7
A. Parallel
B. Perpendicular
C. Neither
Answers
Answer:
A
Step-by-step explanation:
Because the have the same slope.
The second equation solving for y is:
Y= -2x+7.
Both equations have the same slope of -2
Answer:
Parallel
Step-by-step explanation:
If lines have the same slope, then they are parallel. If lines have slopes that are opposite reciprocals of each other, then they are perpendicular. If neither one of those statements are true, then the answer is neither.
1) First, find the slope of the first equation. [tex]y = -2x + 3[/tex] is already in [tex]y = mx + b[/tex] format, or slope-intercept form. The [tex]m[/tex], or the coefficient of the x term, represents the slope. Thus, by looking at the equation, -2 is the slope of [tex]y = -2x + 3[/tex].
2) Second, find the slope of the second equation. [tex]2x + y = 7[/tex] is in standard format, but we can change it to slope-intercept format by isolating the y like so (just subtract both sides by 2x):
[tex]2x + y = 7 \\y = -2x + 7[/tex]
Now that it is in slope-intercept form, we can look at the coefficient of the x term, or [tex]m[/tex], to find the slope. That number is -2, thus the slope of [tex]2x + y = 7[/tex] is -2.
3) We found out that the slopes of both equations are -2. Thus, since they share the same slope, the lines are parallel.
6 - 2y + (-8y) + 5.1 = 0
(Simplify your answer. Use integers
Answers
Answer:
Simplified answer = 11.1 - 10y = 0
y = 1.11
Step-by-step explanation:
6 - 2y + (-8y) + 5.1 = 0
6 + 5.1 -2y -8y = 0
Add like terms
11.1 - 10y = 0
(This is simplified, but if you want to solve for y, continue)
11.1 - 10y = 0
÷10 ÷10
1.11 - y = 0
y = 1.11 because 1.11 - 1.11 is 0

I buy a T.V for 10,000 and sell it at profit of 20%. how much do I get
Answers
Answer:
12,000
Step-by-step explanation:
Cost Price of T.V. = Rs. 10000
Profit percent = 20%
Profit = Profit% of C.P.
= 20 divided by 100 multiply by 1000
= Rs 2000
Selling price = C.P. + Profit
= 10000 + 2000 = 12000
Hence, the answer is Rs. 12,000 on selling the T.V.
Hope this helps you!
Write the equation of this circle in standard form. A) (x - 2)2 + (y - 3)2 = 4 B) (x + 2)2 + (y + 3)2 = 4 (x - 2)2 + (y - 3)2 = 16 D) (x + 2)2 + (y + 3)2 = 16
Answers
Answer:
The answer is C.
Step-by-step explanation:
The equation of the circle (x - 2)² + (y - 3)² = 16 if the center of the circle is (2, 3) and the radius is 4 units option (C) is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The graph of the circle is given in the picture:
The center of the circle is (2, 3) and the radius of the circle is 4 units
As we know, the standard equation of the circle is:
(x - h)² + (y - k)² = r²
Here (h, k) and r is the center of the circle and the radius of the circle.
h = 2 and k = 3
r = 4 plug all the values in the equation:
(x - 2)² + (y - 3)² = 4²
(x - 2)² + (y - 3)² = 16
Thus, the equation of the circle (x - 2)² + (y - 3)² = 16 if the center of the circle is (2, 3) and the radius is 4 units option (C) is correct.

Roberto must make his costume for his school play. He needs a piece of fabric that is 2 2/3 yards long and 1 1/2 yards wide. What is the piece of fabric Roberto needs?
Answers
Answer:
He will need 8.34 yards of fabric.
Step-by-step explanation:
Given that,
The length of the fabric, l = 2 2/3 yards = 8/3 yards
The width of the fabric, b = 1 1/2 yards = 3/2 yards
We need to find the piece of fabric Roberto needs. It is equal to the perimeter of the fabric such that,
[tex]P=2(l+b)\\\\P=2(\dfrac{8}{3}+\dfrac{3}{2})\\\\P=2\times \dfrac{25}{6}\\\\P=8.34\ \text{yards}[/tex]
So, he will need 8.34 yards of fabric.

honestly in my opinion that’s the answer.

then divide 2.5884 by the power of ten, wich is moving the decimal to left with how many zeros their are.
-0.25884
since in 10 their is only one 0 we moved the decimal only one time to the left.
and that’s how I came to that solution.
