Answer: Here we will tell you what 630 is rounded to the nearest hundred and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the hundred that is nearest to 630.
First, 630 rounded to the nearest hundred is: 600
When rounding to the nearest hundred, like we did with 630 above, we use the following rules:
A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
Step-by-step explanation:
Rounding 630 to the nearest hundred results in 600.
To round the number 630 to the nearest hundred, consider the tens digit of the number.
In this case, the tens digit is 3.
If the tens digit is 5 or greater, you round up to the next hundred.
If the tens digit is 4 or less, you round down to the current hundred.
Since the tens digit in 630 is 3, which is less than 5, you round down.
Therefore, rounding 630 to the nearest hundred results in 600.

_[blank]_ square inches
Answer:
2462.4 square inches
Step-by-step explanation:
To find the length of the longer wall use the following ratio and solve for x.
x/36= 4.75/ 2.5
x= 68.4
Area of a rectangle = l(w)
68.4(36)= 2462.4 square inches
The area of the wall is the product of its dimension.
The area of the actual wall is 2462.4 square inches
The scale is given as:
[tex]\mathbf{Scale = 4.75 : 2.5}[/tex]
The shorter side of the actual wall is 36 inches.
So, we have:
[tex]\mathbf{Long : 36= 4.75 : 2.5}[/tex]
Express as fractions:
[tex]\mathbf{\frac{Long }{36}= \frac{4.75 }{ 2.5}}[/tex]
Multiply both sides by 36
[tex]\mathbf{Long= 36 \times \frac{4.75 }{ 2.5}}[/tex]
[tex]\mathbf{Long= 68.4}[/tex]
So, we have:
[tex]\mathbf{Long= 68.4}[/tex]
[tex]\mathbf{Short= 36}[/tex]
The area is then calculated as:
[tex]\mathbf{Area = 68.4 \times 36}[/tex]
[tex]\mathbf{Area = 2462.4in^2}[/tex]
Hence, the area of the actual wall is 2462.4 square inches

The sale price of a trampoline before tax is $300 the sales tax is 4% find the sales tax in the total price of the trampoline
The trampoline will attract a sales tax of $12 which will take its total price to $312.
The trampoline costs $300 without taxes being accounted for yet.
The tax is 4%. In dollar terms this is:
= Sales tax percentage x Cost of trampoline
= 4% x 300
= $12
The total price of the trampoline will therefore be:
= Cost of trampoline + sales tax
= 300 + 12
= $312
In conclusion, the sales tax would be $12 and the total price would be $312.

A 36 foot long roll of banner material must be cut into three pieces with no material left over to make three banners. The second banner must be 4 feet longer than the first banner in the third banner must be also 4 feet longer than the second. How long should each banner be
Answer:
The length of the first banner = 8 ft
The length of the second banner = 12 ft
The length of the third banner = 16 ft
Step-by-step explanation:
The total length of the banner material = 36 ft
Now, let us assume the length of the first banner = k ft
So, the length of the second banner = First banner + 4 ft = ( k + 4) ft
The length of the third banner = Second banner + 4 ft = [( k + 4) + 4] ft
Now, according to the question:
The length of ( First + Second + Third) banner = 36 ft
⇒ (k) + (k +4) + (k + 8) = 36
or, 3 k = 36 - 12= 24
or, k = 24/3 = 8
⇒ k = 8 ft
So, the length of the first banner = k = 8 ft
The length of the second banner = k + 4 = 8 + 4 = 12 ft
The length of the third banner = k + 4 + 4 = 8 + 8 = 16 ft

A school is arranging a field trip to the zoo. The school spends 875.49 dollars on passes for 29 students and 4 teachers. The school also spends 279.56 dollars on lunch for just the students. How much money was spent on a pass and lunch for each student?
Answer:
Money spent on each student is $36.17
Step-by-step explanation:
$875.49 = 29 students & 4 teachers
33 people = $875.49
1 person = $26.53 (pass)
29 students = $279.56
1 student = $9.64 (lunch)
each student = $9.64 + $26.53
= $36.17
the amount spent on a pass and lunch for each student is approximately $26.56 + $9.63 = $36.19.
To find out how much money was spent on a pass and lunch for each student, we need to calculate the total amount spent on passes and lunch and then divide it by the total number of students.
Given:
- Total amount spent on passes for 29 students and 4 teachers: $875.49
- Total amount spent on lunch for just the students: $279.56
- Total number of students: 29
1. First, let's find the total amount spent on passes for just the students:
Total amount spent on passes for students and teachers = $875.49
Total amount spent on passes for 4 teachers = ?
Total amount spent on passes for students = $875.49 - (amount spent on passes for teachers)
Since each pass costs the same amount for students and teachers, we can divide the total amount spent on passes by the total number of passes (students + teachers) to find the cost per pass.
Total number of passes (students + teachers) = 29 students + 4 teachers = 33 passes
Cost per pass = Total amount spent on passes / Total number of passes
= $875.49 / 33
≈ $26.56 (rounded to two decimal places)
2. Now, let's find out how much money was spent on lunch for each student:
Total amount spent on lunch for students = $279.56
Cost per student for lunch = Total amount spent on lunch for students / Total number of students
= $279.56 / 29
≈ $9.63 (rounded to two decimal places)
So, the amount spent on a pass and lunch for each student is approximately $26.56 + $9.63 = $36.19.

1. Use the formula S(d)=√9.8d to calculate the estimated speed, in meters per second, of a tsunami if the disturbance occurred at an ocean depth of 4,500 meters.
2. Convert the answer from question one from meters per second to kilometers per hour. (Hint: A meter per second is equal to 3.6 kilometers per hour.)
Answer: 1. 210 meters per second .
2. 756 kilometers per hour.
Step-by-step explanation:
Given : The formula [tex]S(d)=\sqrt{9.8d}[/tex] to calculate the estimated speed, in meters per second of a tsunami.
1. If the disturbance occurred at an ocean depth of 4,500 meters.
Then put d= 4500 in the above formula , we get
[tex]S(d)=\sqrt{9.8\times4500}[/tex]
[tex]S(d)=\sqrt{44100}=\sqrt{21\times21\times10\times10}\\\\=\sqrt{210^2}=210[/tex]
Hence, if the disturbance occurred at an ocean depth of 4,500 meters , the estimated speed would be 210 meters per second .
Also, A meter per second is equal to 3.6 kilometers per hour.
i.e. 1 meter per second = 3.6 kilometers per hour
Then by unitary method ,
210 meters per second =[tex]3.6\times210[/tex] kilometers per hour
=756 kilometers per hour.

. Each house number on Maple Street is six more than the house number to its left.
• Each house number on Oak Street is eight more than the house number to its left.
How much greater is the house number of the last house on Oak Street than the house
number of the last house on Maple Street
The last house on Oak Street has a house number 8 greater than the last house on Maple Street.
The correct answer is option C.
Let's denote the house numbers on Maple Street as M1, M2, M3, M4, and M5, where each house number is six more than the one to its left. Similarly, on Oak Street, denote the house numbers as O1, O2, O3, O4, and O5, where each house number is eight more than the one to its left.
For Maple Street:
M2 = M1 + 6
M3 = M2 + 6
M4 = M3 + 6
M5 = M4 + 6
For Oak Street:
O2 = O1 + 8
O3 = O2 + 8
O4 = O3 + 8
O5 = O4 + 8
Now, let's find the difference between the last house on Oak Street (O5) and the last house on Maple Street (M5):
The difference is (O4 + 8) - (M4 + 6) = (O3 + 8 + 8) - (M3 + 6 + 6) = (O2 + 8 + 8 + 8) - (M2 + 6 + 6 + 6) = (O1 + 8 + 8 + 8 + 8) - (M1 + 6 + 6 + 6 + 6).
Simplifying the expression, the constant terms cancel out, leaving:
The difference is O1 - M1 + (8 + 8 + 8 + 8) - (6 + 6 + 6 + 6) = O1 - M1 + 32 - 24 = O1 - M1 + 8.
So, the house number of the last house on Oak Street is 8 greater than the house number of the last house on Maple Street.
The question probable may be;
The picture below shows 5 houses on maple street anf the five houses on oak street.
Each house number on maple street is six more than the house number to its left. Each house number on oak street is eigth more than the house number to its left.
How much greater is the house number of the last house on oak street than the house number of the last house on maple street?

You want it put edging around a rectangular flower garden that is 15 feet long and 12 feet wide. The edging comes in 3 foot pieces. How many pieces of edging do you need to buy
Answer:
18 pieces are needed
Step-by-step explanation:
Edgings are put all around the rectangular flower garden. So we need to know the perimeter (sum of all sides) of the rectangle. The formula is:
Perimeter of Rectangle = 2(Length + Width)
Given,
Length = 15
Width = 12
So,
Perimeter = 2(Length + Width)
Perimeter = 2(15 + 12)
Perimeter = 2(27)
Perimeter = 54
So, we need to cover 54 feet. Each edging is 3 feet in length, so 54 feet will be covered by:
54/3 = 18 edgings
When buying groceries at the store for this dinner, you can spend no more than $100. Some costs are fixed, like spices and piecrusts. That total comes to $65. The turkey, however, is priced per pound. The suggestion is that you plan for 1.5 pounds of turkey per guest. If the turkey costs $1.16 per pound, what is the largest size turkey you should buy and how many people can it feed?
Answer:
20 full people
Step-by-step explanation:
100-65=35
35/1.16= 30.1724
30.1724/1.5=20.1149
You can't feed a .1149 of a person so 20 people
Given the maximum budget and cost per pound, the largest turkey you can purchase is approximately 30.17 pounds. This will feed about 20 guests, considering each person consumes 1.5 pounds of turkey.
Explanation:The subject of this question is mathematics, specifically, problem-solving involving budgets and limits. Given that the maximum budget for this dinner is $100 and the fixed costs total to $65, we're left with $35 for the turkey. Each pound of turkey is priced at $1.16.
By dividing the remaining amount of money (which is $35) by the cost per pound of turkey (which is $1.16), we compute the total pounds of turkey we can afford. That is, $35 / $1.16 = approximately 30.17 pounds.
Each guest requires 1.5 pounds of turkey, so we now calculate how many guests can be fed by this amount of turkey. We do this by dividing the total pounds of turkey (30.17 pounds) by the amount required per guest (1.5 pounds), which gives us 30.17 / 1.5 = approximately 20.11. Since you can't invite a fraction of a person, the largest size turkey you can afford can feed about 20 people.

3. A crate with 20 bricks weighs 167 pounds. When the same crate has 32 bricks, it weighs
191 pounds. How much would the crate weigh if there were 19 bricks in the crate?
Explain.
The weight of crate when it has 19 bricks is 165 pounds
Solution:Given that, A crate with 20 bricks weighs 167 pounds.
When the same crate has 32 bricks, it weighs 191 pounds.
Now, let the weight of each brick be "m" pounds and weight of the crate be 'n" pounds.
Then, when crate has 20 bricks
Total weight = weight of bricks + weight of crate
[tex]167 \text { pounds }=\text { number of bricks } \times \text { weight of each brick }+\text { weight of crate }[/tex]
[tex]167=20 \times m+n[/tex]
20m + n = 167 ----- eqn (1)
Now, when crate has 32 bricks
Total weight = weight of bricks + weight of crate
[tex]191 \text { pounds }=\text { number of bricks } \times \text { weight of each brick + weight of crate }[/tex]
[tex]191=32 \times m+n[/tex]
32m + n = 191 ----- eqn (2)
Now, subtract (1) from (2)
32m + n = 191
20m + n = 167
(-) ----------------
12m + 0 = 24
m = 2
Then, from eqn (1)
20(2) + n = 167
40 + n = 167
n = 167 – 40 = 127
Now, when the box has 19 bricks
Total weight = 19 bricks x 2 pounds per brick + 127 pounds of crate
[tex]\text { Total weight }=19 \times 2+127=38+127=165[/tex]
Hence, the weight of crate when it has 19 bricks is 165 pounds.

y ≤ −x − 4
-10<-1-5
-10<-6
Pair: (1,-10)
Answer:
(1, −10)Step-by-step explanation:
If we graph this system of inequalities, we could find the solution.
From the graph you can deduct that the only right answer is the last one (1,-10), because the area of solution is only for negative values of y.
Therefore, the right choice is the last one.
If you can't graph, you can try another method. If we replace the value in the system, it should satisfy it, that is, it should gives us a true result like 0<1 for example. Let's try
For x=1 and y=-10, we have
-10 ≤ 1 − 5
-10 ≤ −1 − 4
-10 ≤ -4
-10 ≤ -5
As you can see, the result is true, because -10 is less than -4 and -5, so that's the right answer.
A card is randomly selected from a standard deck of 52 playing cards. What is the probability that it is a face card or a spade?
Answer:
8/13.
There's 12 face cards & 26 black cards. In the 26 black cards, theres 6 face cards. Theres 32 cards overall that is either a black card or a face card. So in conclusion the answer is 8/13 because 52 (the total amt in the deck) divided by 32 = 8/13.
The probability of randomly selecting either a face card or a spade from a standard deck of 52 playing cards is approximately 0.4231.
The question involves calculating the probability of selecting either a face card or a spade from a standard deck of 52 playing cards. A standard deck consists of four suits (spades, hearts, diamonds, clubs), each with 13 cards, making a total of 52 cards. Among these, 12 are face cards (Jacks, Queens, Kings across all suits), and 13 are spades (including the spade face cards).
First, note that there are 3 face cards (Jack, Queen, King) in each suit, resulting in 12 face cards in total. However, 3 of these face cards are spades, and we must avoid double-counting them when adding the spade cards. Therefore, we have 12 face cards and 10 non-face card spades (since 3 spades are already counted among face cards), giving us a total of 22 unique cards that fulfill the conditions.
The probability of drawing either a spade or a face card from a deck of 52 cards is calculated by dividing the number of favorable outcomes (22) by the total number of outcomes (52), which is 22/52 or approximately 0.4231.

Mitch paid $ 33600 altogether
Solution:Given that mitch took out a school laon for $ 24000
The interest rate on the loan was 8%
Number of years = 5
To find: total amount paid altogether
We can use simple interest to calculate the total amount
Total amount paid altogether = simple interest + principal amount
The simple interest is calculated as:
[tex]\text { simple interest }=\frac{\text { principal } \times \text {rate of interest } \times \text {number of years}}{100}[/tex]
Plugging in values, we get
[tex]\text { simple interest }=\frac{24000 \times 8 \times 5}{100}=240 \times 8 \times 5=9600[/tex]
Total amount paid altogether = simple interest + principal amount
Total amount paid altogether = 9600 + 24000 = 33600
Thus Mitch paid $ 33600 altogether
