Answers
The total length of the strip of the wood would be =2,267.0 in²
How to determine the length of the strip of the wood?From the reference given above concerning "the story of a battle”, it has the shape of a rectangule. The total length of the strip of wood to be used depends on the area of the rectangular artwork.
Area of a rectangle = length× width.
Where;
Length = 55⅛ in
Width = 41⅛ in
Area = 55⅛ × 41⅛
= 441/8 × 329/8
= 145089/64
= 2,267.0 in²

Frank has x grapes.
Gabriel has two fewer grapes than Frank.
Himali has five times as many grapes as Frank.
If Gabriel has 6 grapes how many does Hamali have?
Pls give answer and solution as well. Much appreciated
Answers
Answer:
40 grapes
Step-by-step explanation:
Since Frank has x grapes,
No. of grapes Gabriel has = (x-2) grapes
No. of grapes Himali has = 5 × x
= 5x grapes
x-2 = 6
x = 6 + 2
= 8
5x = 8 × 5
= 40
Hence, Himali has 40 grapes.

A 15 meter long cylinder with a diameter of 7 meters has a square prism
with a base length of 4 meters hole going all the way through the center of
it as shown in the diagram (not to scale). Find the volume of the composite
shape rounding to the nearest cubic meter.
Answers
Answer:
The volume of the composite figure is approximately 337.27 m³
Step-by-step explanation:
The given parameters are;
The length of the cylinder, L = 15 meters
The diameter of the cylinder, D = 7 meters
The base length of the square prism, B = 4 meters
We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder
Therefore, we have;
The volume of the composite figure = The volume of the cylinder - The volume of the square prism
The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³
The volume of the square prism = B² × L = 4² × 15 = 240 m³
∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³
The volume of the composite figure ≈ 337.27 m³.

Linda hears a story on National Public Radio stating that one in six eggs in the US are contaminated with Salmonella. If Salmonella contamination occurs independently within and between egg cartons and Linda makes a three-egg omelet, what is the probability that her omelet will contain at least one Salmonella-contaminated egg?
Answers
The probability that Linda's omelet will contain at least one Salmonella-contaminated egg is approximately 0.4213 or 42.13%.
We have,
To calculate the probability that Linda's omelet will contain at least one Salmonella-contaminated egg, we can use the concept of complementary probability.
The complementary event to "at least one Salmonella-contaminated egg" is "no Salmonella-contaminated eggs."
The probability of no Salmonella-contaminated eggs in a three-egg omelet is (5/6) x (5/6) x (5/6) since each egg has a 1/6 probability of not being contaminated.
Therefore,
The probability of at least one Salmonella-contaminated egg is:
= 1 - (5/6) x (5/6) x (5/6)
= 91/216 or approximately 0.4213.
Thus
The probability that Linda's omelet will contain at least one Salmonella-contaminated egg is approximately 0.4213 or 42.13%.

Step-by-step explanation:
2x-3=1
then you want to add 3 to both sides
2x=4
divide both sides by 2 to get x by it self

x = 2
Step-by-step explanation:
2x - 3 = 1
You’re not really looking for what it results to, instead, you’re looking for the value of x
so first step is isolate
2x - 3 = 1
Since -3 is a negative number and we want to undo that number, we’re going to add by 3 to both sides.
2x = 4
Now to find the value of x, divide both sides by 2

The same center and a smaller margin of error. E. The same center, but the margin of error changes randomly.
Answers
As a result, for the same data set, a 99% confidence interval would have a greater margin of error than a 90% confidence interval.
Answer: If a 90% confidence interval is constructed based on a sample of data, and it is 74% + 3%, a 99% confidence interval based on this same sample of data would have a larger margin of error and probably a different center.
What is a confidence interval? A confidence interval is a statistical technique used to establish the range within which an unknown parameter, such as a population mean or proportion, is likely to be located. The interval between the upper and lower limits is called the confidence interval. It is referred to as a confidence level or a margin of error.
The confidence level is used to describe the likelihood or probability that the true value of the population parameter falls within the given interval. The interval's width is determined by the level of confidence chosen and the sample size's variability. The confidence interval can be calculated using the standard error of the mean (SEM) formula
.A 90% confidence interval indicates that there is a 90% chance that the interval includes the population parameter, while a 99% confidence interval indicates that there is a 99% chance that the interval includes the population parameter.
When the level of confidence rises, the margin of error widens. The center, which is the sample mean or proportion, will remain constant unless there is a change in the data set. Therefore, alternative A is the correct answer.

Answers
Answer:
Step-by-step explanation:
Total surface area of a cone is given by the expression,
SA = πrl + B
Here, r = Radius of the circular base
l = slant height
B = Surface area of the base
Surface area of the circular base = πr²
= π(5)²
= 25π cm²
Slant height 'AC' = \(\sqrt{AB^2+BC^2}\)
= \(\sqrt{h^2+r^2}\)
= \(\sqrt{5^2+(12)^2}\)
= 13 cm
Substitute the values in the expression of surface area,
SA = π(5)(13) + 25π
= 65π + 25π
= 90π cm²
Therefore, SA = 90π cm² will be the answer.

Answers
Answer:
Step-by-step explanation:
(7y+4)/(y+2)=-4/3
\(\dfrac{7y+4}{y+2}=\dfrac{-4}{3}\\\\\)
Cross multiply,
(7y + 4) * 3 = -4*(y+ 2)
Use distributive property,
7y*3 + 4*3 = -4*y + 2*(-4)
21y + 12 = -4y - 8
Subtract 12 from both side
21y = -4y - 8 - 12
21y = -4y - 20
21y + 4y = -20
25y = -20
y = -20/25
\(y=\dfrac{-4}{5}\)
\(\\ \sf\longmapsto \dfrac{7y+4}{y+2}=\dfrac{-4}{3}\)
\(\\ \sf\longmapsto 3(7y+4)=-4(y+2)\)
\(\\ \sf\longmapsto 21y+12=-4y-8\)
