Answers
The ratio of the surface area to the volume of the tank is 3 : 4
What is volume?The volume of a shape is the amount of space in it
How to determine the ratio?The given parameter is
Diameter, d = 8.0 inches
Calculate the radius of the above diameter
So, we have
r = d/2
Substitute the known values in the above equation
r = 8/2
Evaluate
r = 4
The surface area of a sphere is
A = 4πr²
Where r represents radius
So, we have
A = 4π(4)²
The volume of a sphere is
V = 4/3πr³
Where r represents radius
So, we have
V = 4/3π(4)³
The ratio is represented as
Ratio = A : V
So, we have
Ratio = 4π(4)² : 4/3π(4)³
Divide by 4³π
Ratio = 1 : 4/3
Multiply the ratio by 3
Ratio = 3 : 4

Why were the colonists prepared to meet the British at the Battles of Lexington and Concord?
OA. They had organized their own sovereign governments and militias.
OB. They had feared and prepared for British efforts to seize their arms.
C. They knew that war had already been declared by British authorities.
OD. They believed that they could prevent open conflict by showing their resolve.
Answers
The British invaded Lexington and Concord with the goal of disarming any potential rebels by taking their guns.Instead, the Revolutionary War's opening conflict was precipitated by their activities.
Why did the battle of Lexington and Concord happen?
The American Revolutionary War began on April 19, 1775, with the Battles of Lexington and Concord (1775-83).Residents of the 13 American colonies and the British government had been at odds for many years, especially in Massachusetts.Hundreds of British soldiers marched from Boston to nearby Concord that evening, April 18, 1775, in attempt to take an arsenal.The Redcoat column was about to be intercepted when Paul Revere and other horsemen raised the alarm.The conflict began with an altercation on the Lexington town green, and soon the British were fleeing under heavy fire.After numerous additional conflicts, the colonists finally achieved official independence in 1783. Battles of Lexington and Concord's lead-upGreat Britain began taking a number of actions in 1764 to increase revenue from its 13 American possessions.The colonists revolted against "taxation without representation" as a result of many of these laws, such as the Sugar Act, Stamp Act, and Townshend Acts.One of the biggest hubs of opposition was Boston, the location of the 1770 Boston Massacre and the 1773 Boston Tea Party.In June 1774, King George III of Britain increased the military presence there and closed the city's harbor until the colonists paid for the tea that had been poured overboard the year before.The British Parliament soon after declared that Massachusetts was in full-fledged rebellion. Paul Revere never yelled the infamous remark that was later ascribed to him ("The British are coming!") as he traveled from town to town on April 18, 1775, at midnight.Considering that large numbers of British soldiers were skulking in the countryside of Massachusetts, the operation was designed to be carried out as covertly as possible.Colonial Americans also thought of themselves as British at that time.A source inside the British high command informed Joseph Warren, a physician and Sons of Liberty member, on April 18 that Redcoat troops would march on Concord that evening.Paul Revere, a silversmith, and William Dawes, a tanner, were sent as two messengers by Warren to inform the populace. In the event that one of them was captured, they took separate paths.To reach Charlestown, where fellow Americans were waiting for a signal regarding the movement of British troops, Revere traveled across the Charles River by boat.The Old North Church steeple in Boston, Massachusetts, was pointed out to the patriots to be seen because it was the highest point in the city.The British were coming by land if there was even a single lantern hanging in the steeple.In the event that there were two, the British arrived by sea.The secret signal was commemorated by American poet Henry Wadsworth Longfellow in his poem "Paul Revere's Ride," where he stated: "If by land, one; if by sea, two; and I on the other shore, ready to ride and give the alarm Through every Middlesex village and farm, For the country men to be up and to arm."Dawes left Boston and made his way along the Boston Neck peninsula as Revere completed his mission in Charlestown.A few miles east of Concord, where revolutionary leaders John Hancock and Samuel Adams had taken refuge, the two came together in Lexington.Revere and Dawes set out again after successfully convincing those two to go.They encountered Samuel Prescott, a third rider, who traveled all the way to Concord by himself.A British patrol arrested Revere, while Dawes escaped.

What are Decimals?A decimal numeral is a broad term for a number's notation using the decimal numeral system. Sometimes a decimal separator is used to identify decimals. Integer and non-integer numbers are often expressed using the decimal numeral system. The Hindu-Arabic numeral system has been expanded to include non-integer values. Term "terminating decimals" refers to decimal numerals in this context that have a predetermined number of non-zero digits following the decimal separator. An infinite decimal that, after a certain point, repeats the same digit sequence endlessly is said to be repeating. If and only if it has a finite number of non-zero digits or is a repeating decimal, an infinite decimal can be used to represent a rational number, the product of two integers.Therefore,
-8/5 = -1.6 …............ Number 3
-1.7 …............ Number 2
-30/-25 = 6/5 = 1.2 …............ Number 4
-1.71 .................. Number 1

What is division?
Division is the process by which value of single unit can be calculated from the value of multiple unit.
The number to be divided is known as dividend, the number by which the dividend is divided is the divisor, the result obtained is the quotient and the remaining part is the remainder.
There is a well known formula for division
Divisor x Quotient + Remainder = Dividend.
Here,
Total number of apples = 9918
Number of apples in one crate = 21
Total number of apples = 9918 ÷ 21
Quotient of 9918 ÷ 21 = 472 and remainder = 6

Explanation:
To find thh correct category, we need to calculate the amount spend on each category for each family, so taking into account the circle graphs, we get:
Family A (income: $5,400)
Housing: 5400 x 19% = 1026
Food: 5400 x 14% = 756
Childcare: 5400 x 18% = 972
Transportation: 5400 x 11% = 594
Insurance: 5400 x 23% = 1242
Other Needs: 5400 x 9% = 486
Taxes: 5400 x 5% = 270
Saving: 5400 x 1% = 54
Family B (income $4675)
Housing: 4675 x 16% = 748
Food: 4675 x 16% = 748
Childcare: 4675 x 18% = 841.5
Transportation: 4675 x 13% = 607.75
Insurance: 4675 x 28% = 1309
Other Needs: 4675 x 7% = 327.25
Taxes: 4675 x 2% = 93.5
Family C (income: $6675):
Housing: 6675 x 14% = 934.5
Food: 6675 x 11% = 734.25
Childcare: 6675 x 30% = 2002.5
Transportation: 6675 x 9% = 600.75
Insurance: 6675 x 20% = 1335
Other Needs: 6675 x 6% = 400.5
Taxes: 6675 x 10% = 667.5
Now, we need to calculate the differences in each categories:
Housing
A - B = 1026 - 748 = 278 > 25
Food
A - B = 756 - 748 = 8
B - C = 748 - 734.5 = 13.5
A - C = 756 - 734.25 = 21.75
Childcare
A - B = 972 - 841.5 = 130.5 > 25
Transportation
A - B = 594 - 607.75 = -13.75
B - C = 607.75 - 600.75 = 7
A - C = 594 - 600.75 = -6.75
Insurance
A - B = 1242 - 1309 = -67 < -25
Other Needs
A - B = 486 - 327.25 = 158.75 < 25
Taxes
A - B = 270 - 93.5 = 176.5 > 25

To find angle at O, we employ the angle at centre is 2ce that subtended at circumference making angle at O = 2 x 65 = 130 degrees.
Now we have Quadilateral ABOC and we know that the total angles in a quadrilateral are 360 degrees.

If 450 people attended the tournament, and a total of $4,200 was collected in ticket fees, how many students attended the tournament?
60
100
200
280
Answers
The number of students that attended the tournament is 100.
How many students attended the tournament?The simultaneous equations that would be used to solve this question is:
10a + 7s = 4,200 equation 1
a + s = 450 equation 2
Where:
a = number of adults s = number of studentsThe elimination method would be used to solve the equations.
Multiply equation 2 by 10
10a + 10s = 4500 equation 3
3s = 300
Divide both sides of the equation by 3
s = 300 / 3
s = 100
