Answer:
8 ears of corn for $2.56
Step-by-step explanation:
Which bag is the better deal?
to determine which bag is the better deal, determine the price per ear of corn
price per ear = total price / total ears
$2.56 / 8 = $0.32
$4.32 / 12 = $0.36
the cheaper ear is the 8 ears of corn for $2.56

Answer:
x< 10
Step-by-step explanation:
To start the absolute difference between 20 and 5 is 15. Next, write out an equation for the problem:
x * 1.5 < 15,
Then divide by 1.5 on both sides...
Boom! x < 10.

A. y−4=−611(x−1)
B. y+1=−611(x+4)
C. y+7=−611(x−7)
D. y−7=−611(x+7)
Answer:
D) y-7=-6/11(x+7)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(1-7)/(4-(-7))
m=-6/(4+7)
m=-6/11
y-y1=m(x-x1)
y-7=-6/11(x-(-7))
y-7=-6/11(x+7)
y=-6/11x-42/11+7
y=-6/11x-42/11+77/11
y=-6/11x+35/11
which expression represents the difference of (5x-3y) and (8x+8y)?
Given:
The expressions are:
[tex](5x-3y)[/tex] and [tex](8x+8y)[/tex]
To find:
The difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex].
Solution:
Difference of [tex](5x-3y)[/tex] and [tex](8x+8y)[/tex] is written as:
[tex]Difference=(5x-3y)-(8x+8y)[/tex]

Find the values of x and y
Answer:
x = 78º
y = 35º
Step-by-step explanation:
These are isosceles triangles
two angles are congruent
-----------------------------
x + 51 + 51 = 180
x = 180 - 102
x = 78º
y + y + 110 = 180
2y = 70
y = 35º
Find center and radius of a circle with a diameter that has endpoints of (3,-2) and (-5,-4)
Answer:
Center: (-1,-3)
Radius: 4.12 units
Step-by-step explanation:
Hi there!
1) Find the center of the circle
When given two diameter endpoints, we can find the center of the circle by calculating for the midpoint since the center lies in the middle of the points:
Midpoint: [tex](\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2})[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the diameter endpoints (3,-2) and (-5,-4)
[tex](\frac{3+(-5)}{2} ,\frac{-2+(-4)}{2})\\(\frac{3-5}{2} ,\frac{-2-4}{2})\\(\frac{-2}{2} ,\frac{-6}{2})\\(-1,-3)[/tex]
Therefore, the circle is centered at (-1,-3).
2) Find the radius of the circle
The radius of a circle is the distance between the outside edge and the center. We can find the radius by calculating for the distance between the center of the circle and one of the diameter endpoints.
Distance formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] where the two points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the center (-1,-3) and a diameter endpoint (3,-2)
[tex]d=\sqrt{(3-(-1))^2+(-2-(-3))^2}\\d=\sqrt{(3+1)^2+(-2+3)^2}\\d=\sqrt{(4)^2+(1)^2}\\d=\sqrt{16+1}\\d=\sqrt{17} \\d=4.12[/tex]
Therefore, the radius of the circle is approximately 4.12 units when rounded to the nearest hundredth.

As a block of ice melts, its weight changes from 1 3/4 lb to 1/4 lb. This change takes 1/4 h. The ice melts at a constant rate. At what rate does the weight of the ice change?
Answer:-You should have these values backwards like:-
=> 1/34 lb is less than 1/4 lb.
Next:-
We're gonna find a specific common denominator,
Then we get: (17/68 - 2/68)/(1/4) = 60/68 = 15/17 lb/hour

Keith has 7 yards of string. He needs ⅓ yard of string for each of his puppets. How many puppets can Keith make with his string?
Answer:
the no of puppets that could be made with his string is 21
Step-by-step explanation:
Given that
There is 7 yards
And, it needs one -third of string for each of his puppets
= 7 × 3
= 21 puppets
We simply multiply the 7 yards with the 3 so that the no of puppets could come
hence, the no of puppets that could be made with his string is 21

ellipse with vertices (-3, 4), (11, 4) and foci (-1, 4), (9.4)?
Answer:
[tex]\frac{(x-4)^2}{49}+\frac{(y-4)^2}{24}=1[/tex]
Step-by-step explanation:
Because the vertices are on the same horizontal line and so are our foci, this is our major axis for a horizontal ellipse.
Horizontal Ellipse:
[tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]
a>b
Major axis length: 2a
Minor axis length: 2b
Center: (h,k)
Foci: (h±c,k) where a²-b²=c²
We can easily find the center of the ellipse by finding the midpoint of our vertices (-3,4) and (11,4) which works out to be (4,4)
Because our foci must be (-1,4) and (9,4) this means (4±c,4) represents our foci. We can easily see that c=5 since (4-5,4) -> (-1,4) and (4+5,4) -> (9,4).
Knowing that c=5, we need to determine our values for a and b to satisfy the equation a²-b²=5². Our vertices are located on the major axis, which will help us in finding the value of a. The distance between the two vertices will be the length of the major axis, which will be |11-(-3)| = 14. Additionally, because the length of the major axis is equal to 2a, this means 2a=14 where a=7. Now we can solve for b with our equation 7²-b²=5² where b=√24.
In conclusion, our ellipse would be:
[tex]\frac{(x-4)^2}{7^2}+\frac{(y-4)^2}{\sqrt{24}^2}=1[/tex] which works out to be [tex]\frac{(x-4)^2}{49}+\frac{(y-4)^2}{24}=1[/tex]
The equation of ellipse with vertices (-3, 4), (11, 4) and foci (-1, 4), (9.4) is
(x-4)^2/49 + (y-4)^2/24 = 1
What is equation of an ellipse?The standard equation of an ellipse centered at (h, k) with a major axis parallel to the x-axis is given by:
(x-h)^2/a^2 + (y-k)^2/b^2 = 1
where the coordinates of the vertex are (h±a, 0), coordinates of co-vertex are (h, k ± b) and the coordinates of foci are (h±c, k), where a² = c² + b².
here, we have,
Because the vertices are on the same horizontal line and so are our foci, this is our major axis for a horizontal ellipse.
Horizontal Ellipse:
(x-h)^2/a^2 + (y-k)^2/b^2 = 1
where,
a>b
Major axis length: 2a
Minor axis length: 2b
Center: (h,k)
Foci: (h±c,k) where a²-b²=c²
We can easily find the center of the ellipse by finding the midpoint of our vertices (-3,4) and (11,4) which works out to be (4,4)
Because our foci must be (-1,4) and (9,4) this means (4±c,4) represents our foci. We can easily see that c=5 since (4-5,4) -> (-1,4) and (4+5,4) -> (9,4).
Knowing that c=5, we need to determine our values for a and b to satisfy the equation a²-b²=5².
Our vertices are located on the major axis, which will help us in finding the value of a.
The distance between the two vertices will be the length of the major axis, which will be |11-(-3)| = 14.
Additionally, because the length of the major axis is equal to 2a, this means 2a=14 where a=7.
Now we can solve for b with our equation 7²-b²=5² where b=√24.
In conclusion, our ellipse would be:
(x-4)^2/49 + (y-4)^2/24 = 1

a triangle has side lengths 10, 16, and 11. is the triangle actue, obtuse, or right?
Answer:
Obtuse
Step-by-step explanation:
a^2 + b^2 = c^2
10^2 + 11^2 = 16^2
100 + 121 = 256
221 = 256
221 < 256
A triangle has side lengths 10, 16, and 11. is the triangle is obtuse.
Name three types of triangles based on angles?Triangles can be classified into three types with respect to their interior angles which are:
1. Acute-angled
2. Obtuse-angled
3. Right-angled
Acute Triangle
An acute triangle is a triangle whose all the three interior angles are acute. In other words, if all interior angles are less than 90 degrees, then it is an acute-angled triangle.
Obtuse Triangle
Obtuse triangles are those in which one of the three interior angles has a measure greater than 90 degrees. In other words, if one of the angles in a triangle is an obtuse angle, then the triangle is called an obtuse-angled triangle.
Right Triangle
A right triangle is a triangle in which one of the angles is 90 degrees. In a right-angled triangle, the side opposite to the right angle (90-degree angle) will be the longest side and is called the hypotenuse.
Three given sides are 10, 11, 16
Let a = 10, b = 11, c = 16
then, [tex]a^{2} +b^{2} = 10^{2} +11^{2}[/tex]
= 100 + 121
= 221
and [tex]c^{2} = 16^{2} =256[/tex]
Since, [tex]a^{2} +b^{2} < c^{2}[/tex]
Thus, given triangle is obtuse.
