What are the ratio of the small box to the medium box?
The first step is to determine the side lengths of the small box.
Side length = ∛64 = 4 in
Side lengths of the medium boxes = 4 x 2 = 8 inches
Volume of the medium box = 8³ = 256 cubic inches
The ratio of the sides of the small box to the medium box = 4 : 8 = 1:2.
The ratio of the area of the small box to the medium box= (4 x 4) : (8 x 8) = 1:4.
The ratio of the volume of the small box to the medium box = 4³ : 8³ = 1 : 8.

Is miguel’s claim correct? yes, the two events are independent because p(nf|pb) = p(nf). yes, the two events are independent because p(pb|nf) = p(nf). no, the two events are not independent because p(pb|nf) ≠ p(pb). no, the two events are not independent because p(pb|nf) ≠ p(nf).
Miguel’s claim is correct Yes, the two events are independent because P(NF | PB) is equal to P(NF) which is 3/4.
What is an independent event?The two events are said to be Independent events if the occurrence of events is not dependent.
We have the given data;

What is Circle?A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
Given that an arc is 46∘
We need to find the measure of the subtending angle inscribed in the circle.
The measure of the angle inscribed in a circle is one-half the measure of the arc it subtends.
The measure of the arc is twice the measure of the subtending inscribed angles.
measure of the angle RST= 1/2 measure of the arc
∠RST=1/2(46)

Derek saves 10% of his paycheck each week to buy a mountain bike the mountain bike costs 340.00 Derek receives a paycheck in the amount of $280.50 each week how many paychecks will Derek have to receive before he has saved enough money to buy the mountain bike
Answer: 13 weeks
Step-by-step explanation:
First you have to find 10% of 340.00 which is 28, so each week he saves 28.00 for his bike. To find how many paychecks he has to recieve you divide 340.00 by 28.00, which is 12.1, since there is a decimal place you have to round it up to 13 because it is a little bit more than 12 paychecks. ;)

Rename 1/5 and 9/10 using the least common denominator.
Answer:
[tex]\frac{2}{10}[/tex] and [tex]\frac{9}{10}[/tex]
Step-by-step explanation:
First, llook at the denomintor. Do 5 and 10 have something in common? 5x2=10 and 10x1=10. The common denominator is 10. Then you mulitply the numerator with what you mulitpierd with the denominator. 9x1=9 and 10x1=10 =[tex]\frac{9}{10}[/tex]. 1x2=2 and 5x2=10 = [tex]\frac{2}{10}[/tex]. So, It is [tex]\frac{2}{10}[/tex] and [tex]\frac{9}{10}[/tex].

What is the lowest common denominator for these fractions?
3/5 and 1/10
15
5
10
Answer:
10
Multiply both parameters by the least common multiple of each.[tex]\frac{3*2}{5 * 2} = \frac{6}{10}[/tex]
[tex]\frac{1*1}{10*1} = \frac{1}{10}[/tex]
The lowest denominator cannot be 5, because that would mean you would have to reduce 1/10, and you cannot since 1/10 is a unit fraction, meaning it has a numerator of 1. However, 3/5 in that scenario would remain the same, since it already has a denominator of 5, but 10 does not have both parameters divisible by 5, therefore, eliminate option B.It is also not A. because A. is too high, option A. would actually be the highest denominator you can go for in this situation, which we are not going for. We are going for the lowest denominator logically possible.________________________________________________________
With that information, the correct answer is option C, 10

The equation needed to calculate the compound interest is [tex]A = P(1 +\frac{r}{n} )^{nt}[/tex]
The value of the account after ten years is $9347.62 .
If the account is left alone for 20 years, the amount of interest earned is $6942.76
How to calculate compound interest?The compound interest formula is represented as follows;
[tex]A = P(1 +\frac{r}{n} )^{nt}[/tex]
where
A = amountP = principalr = raten = compounded months, years etc.t = time in yearsTherefore,
where
r = 3.7% = 3.7 / 100 = 0.037
n = 1
t = 10
P = $6500
Hence,
[tex]A = 6500(1+\frac{0.037}{1} )^{1(10)}[/tex]
[tex]A = 6500(1.037)^{10}[/tex]
[tex]A = 6500(1.43809495884)[/tex]
A = 9347.61723247
A = $9347.62
The value of the account after ten years is $9347.62
Interest = 9347.62 - 6500 = 2847.62 dollars
When it is 20 years.
r = 3.7% = 3.7 / 100 = 0.037
n = 1
t = 20
P = $6500
Hence,
[tex]A = 6500(1+\frac{0.037}{1} )^{1(20)}[/tex]
[tex]A = 6500(2.06811711064)[/tex]
A = 13442.7612192
A = $13442.76
Interest = 13442.76 - 6500 = 6942.76 dollars

A right triangle has one angle that measures 16°. What is the measure of the other acute angle
Answer:
3rd angle = 74
Step-by-step explanation:
Remark
All triangles have 180 degrees.
In addition a right triangle has 1 angle that equals 90 degrees.
That means the other 2 must add to 90.
Givens
1 angle = 90
1 angle = 16
3rd angle = x
Solution
x + 16 + 90 = 180 Sum 3 angles to 180 degrees. Combine
x + 106 = 180 Subtract 106 from both sides.
x = 180 - 106 Combine
Answer: x = 74
Ramon and Hector ride their bikes at constant rates during a race. Ramon rides 45 miles in 3 hours. The distance, y, in miles, Hector rides in x hours is given by the equation y = 18x. Which statement is true?
No answer text provided.
No answer text provided.
Ramon rides his bike 3 miles per hour faster than Hector rides his bike.
Ramon rides his bike 27 miles per hour faster than Hector rides his bike.
Ramon rides his bike 3 miles per hour slower than Hector rides his bike.
Ramon rides his bike 27 miles per hour slower than Hector rides his bike.
We will find the speeds of both persons, the correct option is:
"Ramon rides his bike 3 miles per hour slower than Hector rides his bike."
Which statement is correct?First, we know that Ramon rides 45 miles in 3 hours, then its speed is:
S = 45mi/3h = 15mi/h
And we know that Hector position is given by:
y = 18x
Where x is time in hours, so his velocity is 18mi/h.
Then we can see that:
Ramon's speed = 15mi/hHector's speed = 18mi/hSo the correct statement is:
"Ramon rides his bike 3 miles per hour slower than Hector rides his bike."

The amount more annually a $115,000 10-year term insurance at age 35 cost Bernard than someone of the same age without health issues is $24.
What are insurance premiums?The insurance premium is paid as a cost to cover a possible loss that is unseen.
The annual premium rate as a percentage of the value insured a person at age 35 has to pay is 0.14%.
From the given information, we have that the amount a 35-year-old without health issues will pay per $1,000 is $1.40
The amount to be paid for $115,000 is 115 × $1.4 = $161
The amount Bernard pays = 15% more
= 1.15 × $161
= $185.15
Therefore,
The amount more Bernard has to pay = $185.15 - $161
= $24.15 ≈ $24
