A. 4,000,000,000
B. 4,320,000,000
C. 4,321,000,000
D. 4,322,000,000
Answers
Final answer:
The number 4,321,109,432 rounded to the nearest ten million is 4,320,000,000,hence the correct option is B.
Explanation:
To round the number 4,321,109,432 to the nearest ten million, we need to look at the digit in the ten million's place and the digit to the right of it, which are 3 and 1, respectively. The rule for rounding is that if the digit to the right is 5 or greater, we round up.
In this case, the digit is 1, so we do not round up and the ten million's place remains unchanged.
Therefore, the answer is 4,320,000,000 (Option B), as every digit after the ten million's place is replaced with zero.

A mobile phone carrier charges an extra fee if a customer uses more than 500 minutes each month. Tom has already used 230 minutes this month. Which inequality can be used to determine how many more minutes Tom can use this month without going over the 500-minute limit?
Answers
Answer:
x + 230 ≤ 500
Step-by-step explanation:
Given,
The time for which Tom used the phone = 230 minutes,
Let he further used the mobile for x minutes,
So, the total time for which he used the phone = ( x + 230 ) minutes,
According to the question,
For the extra minutes more than 500 minutes, the mobile phone carrier charges an extra fee,
Thus, if he wants to use the phone, without going over the 500-minute limit,
Then, the total time used by him ≤ 500 minutes,
⇒ x + 230 ≤ 500
Which is the required inequality.

If a horses man grows 6/5 per month, how long will it take to grow 24/10 cm
Answers
Explanation :the horses mane grows 6/5 cm per month lets let x = number of monthsit is going to grow 24/10 in x months
so 6/5x (6/5 times the number of months) = 24/10divide both sides by 6/5, eliminating the 6/5 on the left side.so x = (24/10) / (6/5)...and when dividing fractions, u flip what u r dividing by, and multiply. 24/10 * 5/6 = 120/60 which reduces to 2 months. is the correct answer!
The price of oil recently went from $7.80 to$10.40 per case of quarts. Find the ratio of the increase in price to the original price.
Answers
When you are looking for a ratio, it is simply a fraction.
In the numerator, we will put the amount of the increase which is 10.4 - 7.80 = 2.6.
In the denominator, we will put the original price of $7.80.
This gives us the ration of 2.6/7.8 or just 0.33 if we divide.
We can say there was a 33% increase (or one-third).
I hope this helps, Good luck!

A triangle has two sides that are perpendicular. Could the triangle be isosceles equilateral or scalene? Explain
Answers
Final answer:
A triangle with two perpendicular sides could be scalene or isosceles if the non-perpendicular sides are unequal or equal, respectively. It cannot be equilateral because equilateral triangles have no right angles.
Explanation:
If a triangle has two sides that are perpendicular to each other, it could potentially be a scalene or isosceles triangle, but it cannot be equilateral. When two sides of a triangle are perpendicular, they form a right angle. Thus, if a triangle has a right angle, it is a right triangle by definition. According to Theorem 2, if two angles of a triangle are equal, the opposite sides are equal, and the triangle is isosceles.
In our case, this theorem would apply if the two non-perpendicular sides are of equal length, resulting in an isosceles right triangle. On the other hand, Theorem 3 states that in a triangle with unequal angles, the side opposite the greater of the angles is greater than the side opposite the smaller. Therefore, if the sides forming the right angle are of different lengths, the triangle would be scalene.
two triangles are similar, and the ratio of the lengths of each pair of corresponding sides is 2:1. which statement regarding the two triangles is NOT True?
A- Their corresponding angles have a ratio of 2:!
B- Their areas have a ratio of 4:1
C- Their perimeters have a ratio of 2:!
D- Their altitudes have a ratio of 2:!
Answers
In the case of similar figures, we have the same basic shape however it is just make larger or smaller. Since this is the case, all of the angles will remain the same.
Imagine different sizes of stop signs. They are all similar and all the angles are the same. Only the lengths of the sides change.
All statements are true. Ratio of corresponding angles, areas, perimeters, and altitudes is 2:1. No false statement exists.
To determine which statement regarding the two triangles is NOT true, let's analyze each option step by step.
Given:
- Two triangles are similar.
- The ratio of the lengths of each pair of corresponding sides is 2:1.
Let's denote the lengths of corresponding sides in the first triangle as [tex]\( a \)[/tex], [tex]\( b \)[/tex], and [tex]\( c \)[/tex], and in the second triangle as [tex]\( 2a \)[/tex], [tex]\( 2b \)[/tex], and [tex]\( 2c \),[/tex] respectively.
A. Their corresponding angles have a ratio of 2:1.
- This statement is true because corresponding angles in similar triangles are congruent, so their ratios would indeed be 2:1.
B. Their areas have a ratio of 4:1.
- The area of a triangle is proportional to the square of the length of its sides. So if the ratio of the lengths of corresponding sides is 2:1, the ratio of their areas would be [tex]\( (2:1)^2 = 4:1 \)[/tex]. Hence, this statement is also true.
C. Their perimeters have a ratio of 2:1.
- The perimeters of triangles are directly proportional to the lengths of their sides. Since the ratio of the lengths of corresponding sides is 2:1, the ratio of their perimeters would indeed be 2:1. So, this statement is also true.
D. Their altitudes have a ratio of 2:1.
- The ratio of the altitudes of two similar triangles is equal to the ratio of their corresponding sides. So, if the ratio of corresponding sides is 2:1, the ratio of their altitudes would also be 2:1. Therefore, this statement is true.
Since all the statements are true, the correct answer is NONE.
a rectangular deck has a area of 320 ft squared. the length of the desk is 4 feet longer than the width. find the dimensions of the desk. Solve by completing the square.
Answers
width • (width +4)= 320
Distribute the multiplication over addition and move all to the left side.
w^2 +4w-320=0
(w-16)•(w+20)=0 yet, The product of two things is 0 if one is 0 or both are 0 so
w-16=0 so w=16 and
w+20=0 so w= -20
Now the width or length could not be negative so we discard the solution w=-20.

A town doubles its size every 22 years. If the population is currently 4,500, what will the population be in 88 years?
Answers
4,500×1.50^x=y
4,500 is the population that it starts with, while 1.50 is telling that it is increasing by 50%. X is the number of years.
We are trying to find it in 88 years, so we should replace x with 4. Here is the reason, it doubles every 22 years and we are looking 88 years.
4,500×1.50^4= 22,781.25
There can't be .25 of a person, so the answer would be 22,781.

name each angle in four ways. then classify each angle as acute, right, obtuse, or straight.
Answers
∠ABC
∠CBA
∠B
∠1
Acute: 4, 5
Right: 1
Obtuse: 2, 6
Straight: 3
_____
Note that only angle 1 is known to be a right angle, because it is marked as such. The others appear to have a particular measure, but since they don't have any specific indication of their measure, the appearance cannot be taken at face value. (We suspect you're supposed to use the appearance to answer this question, but don't get in that habit.)
In this geometric scenario, angles are named and classified. Angle 1 is a right angle, angle 3 is a straight angle, angles 2 and 6 are obtuse, while angles 4 and 5 are acute.
Let's name each angle in four ways and classify them:
Angle ABC (B is 90 degrees):
1 (as labeled)
∠ABC (using the vertex B)
∠CBA (using the vertex C)
∠1 (angle 1)
Classification: Right angle
Angle DEF (E is also labeled as 2):
2 (as labeled)
∠DEF (using the vertex E)
∠FED (using the vertex F)
∠2 (angle 2)
Classification: Obtuse angle
On line LN with point M (labeled as 3):
3 (as labeled)
∠LNM (using the vertex N)
∠MNL (using the vertex M)
∠3 (angle 3)
Classification: Straight angle
Angle XYZ (Y is also labeled as 4):
4 (as labeled)
∠XYZ (using the vertex Y)
∠ZYX (using the vertex Z)
∠4 (angle 4)
Classification: Acute angle
Angle KLM (L is also labeled as 5):
5 (as labeled)
∠KLM (using the vertex L)
∠MLK (using the vertex M)
∠5 (angle 5)
Classification: Acute angle
Angle RSP (S is also labeled as 6):
6 (as labeled)
∠RSP (using the vertex S)
∠PSR (using the vertex P)
∠6 (angle 6)
Classification: Obtuse angle
So, to summarize:
Right angle: 1
Obtuse angles: 2, 6
Straight angle: 3
Acute angles: 4, 5

Find the required annual interest rate to the tenth of a percent for $5200 to grow to $6500 if interest is compounded quarterly for five years
Answers
The compound interest formula is
A=p(1+(r/n))^(nt), where A is the total amount including interest earned, p is the principal invested, r is the rate, n is the number of times per year the interest is compounded, and t is the number of years.
With our information we have:
6500=5200(1+(r/4))^(4×5)
6500=5200(1+(r/4))^20
Cancel 5200 by dividing:
6500/5200 = [5200(1+(r/4))^20]/5200
1.25=(1+(r/4))^20
Using a calculator, take the 20th root of each side:
1.25^(1/20) = [(1+(r/4))^20]^(1/20)
1.011219651 = 1+(r/4)
Subtract 1 from each side:
1.011219651-1 = 1+(r/4)-1
0.011219651=r/4
Multiply each side by 4:
0.011219651×4 = (r/4)×4
0.0448786 = r
0.045 = r
Final answer:
After rearranging the formula and solving for the interest rate, the required rate is found to be approximately 4.7%.
Explanation:
The subject of this question is finding the required annual interest rate that will grow a principal amount of $5,200 to $6,500 when compounded quarterly over five years. To solve this, we shall use the compound interest formula:
A = P(1 + r/n)^(nt)
Where:A is the amount of money accumulated after n years, including interest.
P is the principal amount (the initial amount of money).
r is the annual interest rate (decimal).
n is the number of times that interest is compounded per year.
t is the time the money is invested for, in years.
We are given:
A = $6,500
P = $5,200
n = 4 (since interest is compounded quarterly)
t = 5 years
We need to solve for r. First, we rearrange the formula to isolate r:
(1 + r/n) = (A/P)[tex]^({1/(nt))}[/tex]
Then we can insert our known values and solve for r:
(1 + r/4) = ($6,500/$5,200)^(1/(4*5))
Calculate the right-hand side:
(1 + r/4) = (1.25)[tex]^({1/20)}[/tex]
Find the 20th root of 1.25:
(1 + r/4) ≈ 1.01168
Subtract 1 from both sides:
r/4 ≈ 0.01168
Multiply both sides by 4:
r ≈ 0.04672
Convert the decimal to a percentage:
r ≈ 4.672%
Round to the nearest tenth of a percent:
r ≈ 4.7%
Therefore, the required annual interest rate to the tenth of a percent for $5200 to grow to $6500 with interest compounded quarterly for five years is approximately 4.7%.

Community center has an L shaped swimming pool that is 10 feet deep. What is the volume of the pool
1200
1040
640
880
Answers
In order to find this split the pool into two separate rectangular prisms.
The first one's measurements are 4ftx16ftx10ft
4*16*10 = 640
the next prism is 4ftx10ftx10ft
4*10*10 = 400
640+400= 1040 cubic feet
The total volume of pool is:
1040 cubic ft.
Step-by-step explanation:We know that the total volume of the pool is the sum of the volume of two rectangular prism.
one is a rectangular prism with dimensions 20ft.×10ft.×4ft.and the other rectangular prism has dimensions: 6ft.×4ft.×10ft.Hence, the volume of first rectangular prism is:
20×10×4=800 cubic ft.
Volume of second rectangular prism is:
6×4×10=240 cubic ft.
Hence, total volume of pool is:
800+240=1040 cubic ft.
What is the first step of rationalizing the denominator of 7√11√?
Answers
Final answer:
The first step of rationalizing the denominator of 7√11 is to multiply both the numerator and denominator by the conjugate of the denominator.
Explanation:
The first step of rationalizing the denominator of 7√11 is to multiply both the numerator and the denominator by the conjugate of the denominator. In this case, the conjugate of √11 is -√11. Therefore, we multiply both the numerator and denominator by -√11 to get:
7√11 * -√11 = -77
√11 * -√11 = -11
So, the rationalized denominator is -11. The denominator becomes -11, and the simplified expression is:
-77 / -11 = 7
ABC is congruent to FGH, AB=8.3, BC=10.4, and CA=4.2. What is the measure of segment GH?
Answers
For a better understanding of the explanation provided here please go through the diagram in the attachment given below.
As we can see from the diagram of the congruent triangles ABC and FGH, the vertices A,B,C of [tex] \Delta ABC [/tex] correspond to the vertices F,G,H of [tex] \Delta FGH [/tex], so the corresponding sides must correspond too. Thus, AB corresponds to FG, BC corresponds to GH and CA corresponds to GF.
Now, we know that BC=10.4. Therefore, it's corresponding side GH must be 10.4 too because they are corresponding sides of a congruent triangle.
Thus, GH=10.4 is the correct answer.
