Answer:
1344cm^2
Step-by-step explanation:
Semi perimeter:
S = (a+b+c)/2

A sphere has a diameter of 10 in. What is the volume of the sphere?
V = StartFraction 125 Over 3 EndFraction inches cubed
V = StartFraction 500 Over 3 EndFraction inches cubed
V = StartFraction 500 Over 3 EndFraction pi inches cubed
V = StartFraction 4,000 Over 3 EndFraction pi inches cubed
The volume of sphere is [tex]\frac{500}{3}\pi[/tex] inches cubed.
Step-by-step explanation:
Given,
Diameter of sphere = 10 inches
Radius of sphere = [tex]\frac{Diameter}{2}=\frac{10}{2}[/tex]

Amy cut 32 ft of chain into pieces that were each 1/4 ft long. How many of these did Amy have after cutting the chain?
128 pieces can be made after cutting the chain
Solution:
Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long
To find: Number of pieces after cutting the chain
From given,
[tex]\text{Total length of chain } = 32 \text{ feet }\\\\\text{Length of 1 piece } = \frac{1}{4} \text{ feet }[/tex]
Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece
[tex]\text{Number of pieces} = \frac{\text{Total length of chain}}{\text{Length of 1 piece }}[/tex]
Substituting the values, we get
[tex]\text{Number of pieces} = \frac{32}{\frac{1}{4}}\\\\\text{Number of pieces} = 32 \times 4 = 128[/tex]
Thus 128 pieces can be made after cutting the chain
Answer:

The charge to ship a package from one town to another, C, is given below as a function of the weight of the object, w, in pounds.
C = $2.50 + $0.55w
If the shipping cost for Cathy's item was $7.29, what was its weight?
A.
18.7 pounds
B.
0.87 of a pound
C.
87 pounds
D.
8.7 pounds
D) 8.7lbs
Subtract $2.50 from the total cost, because that's a fixed number, then do more math and boom, just like magic, it's solved.
Answer:
8.7 pounds
Step-by-step explanation:
7.29 = 2.5 + 0.55 w
0.55 w = 7.29 - 2.5
0.55 w = 4.79
w = 4.79 / 0.55
w. 8.7

A student bought a piece of hard candy that is in the shape of a sphere. The candy has a radius of 3 centimeters.
Which of the following is closest to the volume of the piece of candy?
(Use 3.14 for π.)
Volume of piece candy is 113.04 cubic centimeter
Solution:
A student bought a piece of hard candy that is in the shape of a sphere
The candy has a radius of 3 centimeters
Radius = 3 cm
Use 3.14 for π
Volume of sphere is given as:
[tex]V = \frac{4}{3} \times \pi \times r^3[/tex]
Where, "r" is the radius of sphere
Therefore, volume of candy is given as:
[tex]V = \frac{4}{3} \times 3.14 \times 3^3\\\\V = 4 \times 3.14 \times 3^2\\\\V = 12.56 \times 9\\\\V = 113.04[/tex]
Thus volume of candy is 113.04 cubic centimeter
A bakery offers a sale price of $2.50 for 3 muffins. What is the price per dozen?
Answer:
$10.0
Step-by-step explanation:
We are given;
Sale price for 3 muffins is $2.50We are required to determine the price per dozen;
We need to know that a dozen contain 12 itemsTherefore;
A dozen of muffins has 12 muffinsThus;
3 muffins = $2.50
12 muffins = (12 ÷ 3) × $2.5
= 4 × $2.50
= $10.0
The Price of a dozen is thus $10.0

Frankenstein in this passage?
O
O
A. Peacefulness
B. Excitement
O
c. Distraction
O
D. Dread
SUBMIT
Answer:
The answer is: letter A, Peacefulness
Explanation:
Mary Shelley is the author of the book entitled, "Frankenstein." The story of the book centers on "Victor Frankenstein," a scientist and his monster creation. This creation of his, later on, asked for a female companion by threatening him. Victor, reluctantly, agreed on this under the monitoring of the creature. In the end of the story, Victor and his men in the ship were trapped in ice.
While Victor was on his journey to Geneva after his brother (William Frankenstein) died, he spoke in the passage above, "I contemplated the lake; the waters were placed; all around was calm, and the snowy mountains, 'the palaces of nature,' were not changed." This made him think how much nature brings peace to his soul that even after turmoil, he felt comforted by nature. Although he dreads to go back, the thought of the calm nature made him continue his journey.
Thus, this explains the answer, "Peacefulness."
Find the perimeter and the area of the polygon with the given vertices. W (11,2), X (11,8), Y (14,8), Z (14,2)
Answer:
The perimeter of the polygon = 18 units
The area of the polygon will be [tex]A=18[/tex] square units
Step-by-step explanation:
Computing the Perimeter of the Polygon:
Considering the polygon with vertices
W (11,2)X (11,8)Y (14,8)Z (14,2)As the polygon is drawn in coordinate plane as shown in figure a.
From the attached figure a, we can observe that
The length of the side [tex]WZ = 3[/tex] unitsThe length of the side [tex]ZY = 6[/tex] unitsThe length of the side [tex]WX = 6[/tex] unitsThe length of the side [tex]XY = 3[/tex] unitsSo, the perimeter of the polygon can be calculated by taking the sum of the lengths of all sides i.e.
The perimeter of the polygon = [tex]WZ + ZY + WX + XY[/tex]
= 3 + 6 + 6 + 3
= 18 units
Computing the Area of the Polygon:
Area can be calculated by multiplying the length and width of the polygon.
[tex]A=lw[/tex]
So, the area will be:
[tex]A=lw[/tex]
[tex]A=(3)(6)[/tex]
[tex]A=18[/tex]
Therefore, the area of the polygon will be [tex]A=18[/tex] square units

different digit sums have different colors. How many different colors of marbles
are there in the container?
Step-by-step explanation:
I'm not certain but I believe it is 29
From 1 to 2015 the number with the highest digit sum is 1999. 1+9+9+9=28. Also digits can add up to all the numbers between 0 and 28 including 0 and 28, making 29 possible sums.

Does the equation y=9x^2+19 represent a linear function?
Because the equation has an (constant of 19/ exponent of 2) , it (can/cannot) be written in the form y=mx+b.
When the equation is graphed, the rate of change between different pairs of coordinates on the graph (is constant/varies) so the graph of the equation is a (curve/point/straight line)
Therefore, the equation represents a (linear/nonlinear) function.
Because the equation has an [tex]\boxed{\text{exponent of 2}}[/tex], it [tex]\boxed{\text{cannot}}[/tex] be written in the form y = mx+b
When the equation is graphed, the rate of change between different pairs of coordinates on the graph [tex]\boxed{\text{varies}}[/tex] so the graph of the equation is a [tex]\boxed{\text{curve}}[/tex]
Therefore, the equation represents a [tex]\boxed{\text{nonlinear}}[/tex] function.
-----------------------------------------------------------------------------------------------------
So in short, y = 9x^2+19 is not linear because it graphs out a curve that isn't a straight line.
More info: The equation y = 9x^2+19 is a quadratic function as the exponent of 2 is the largest exponent. The degree is 2 for the same reason. A parabola will be graphed in this case, which is a curved bowl-like shape. The lowest point of this parabola is at (0,19) which is also the y intercept. There are no x intercepts as this parabola is entirely above the x axis and it goes on forever upward. See the diagram below for the graph of y = 9x^2+19.
The equation y=9x²+19 represents a nonlinear function because it has an exponent of 2, which means it cannot be written in the linear form of y=mx+b. The graph of this equation is a curve, indicating a varying rate of change unlike a straight line which indicates a linear function.
Explanation:The given equation is y=9x²+19. Because the equation has an exponent of 2, it cannot be written in the form y=mx+b, which is the standard form of a linear equation. In linear function, the highest exponent is 1.
When the equation is graphed, the rate of change between different pairs of coordinates on the graph varies. So, the graph of this equation forms a curve. Linear functions have constant rates of change and their graph is a straight line.
Therefore, given the criteria, the equation y=9x²+19 represents a nonlinear function.
