Answer:

3n+5=32

Step-by-step explanation:

this is an example of a 2-step equation.

First, subtract the 5,and cross that out on the left side

and do the same to the other side.

Then you have 3n=32 now, so all you have to do is divide by 3 and you have your answer.

About 68%

Given : The mean speed of a sample of vehicles along a stretch of highway is 66 miles per​ hour, with a standard deviation of 4 miles per hour.

i.e.  

We assume the data set has a​ bell-shaped distribution (i.e. Normal distribution).

To find :  The percent of vehicles whose speeds are between 62 miles per hour and 70 miles per hour.

i.e . The percent of vehicles whose speeds are between  miles per hour and  miles per hour.

i.e . The percent of vehicles whose speeds are between  miles per hour and  miles per hour.

i.e. i.e . The percent of vehicles whose speeds are within one standard deviation from the mean.

According to the Empirical rule , about 68% of the population lies within one standard deviation of the mean.

It means , about 68% of vehicles lies within one standard deviation of the mean.

i.e . About 68% of vehicles whose speeds are between  miles per hour and  miles per hour.

i.e .  About 68% of vehicles whose speeds are between  miles per hour and  miles per hour.

⇒ About 68% of vehicles whose speeds are between 62 miles per hour and 70 miles per hour.

An improper fraction is a fraction where the numerator is greater than the denominator

This is improper because you can't have more parts than the whole. WELL you can, math is confusing

You can have a mixed number, which says how many wholes there are and how many parts of a whole there is.

It's just called an improper fraction just like that I guess,

all you really need to know is that the numerator (the top number) is greater than the denominator (the bottom number), and to make it proper, you have to make it into a mixed number, but you have to use improper fractions to perform some operations.

You'll learn more about converting stuff from improper fractions to mixed numbers and vice versa to perform certain operations in the future, but for now, you just need to know what an improper fraction is.

I hope this helped, let me know if you have any questions.

Answer:

Step-by-step explanation:

An improper fraction is one where the magnitude of the numerator is greater than the magnitude of the denominator.

It is not enough to say that the numerator is greater than the denominator. You need to compare their magnitudes, i.e., their absolute values.

Suppose the fraction is 10/(-23).  10 is greater than -23, but 10/(-23) is not an improper fraction.

Answer:

Step-by-step explanation:

The vertex form of the quadratic equation is ...

  y = a(x -h)² +k . . . . . . . . . vertex (h, k); vertical scale factor 'a'

Given the vertex, we can find the scale factor by substituting the given point values:

  11 = a(-1 -3)² -5

  11 = 16a -5

  a = (11 +5)/16 = 1

So, the vertex form equation is ...

  y = (x -3)² -5 . . . . . vertex form

Expanding this gives the standard form.

  y = x² -6x +9 -5

  y = x² -6x +4 . . . . . standard form

760000 : 10 = 76000

#Divide it by 10 if you want to find how many tens are there

Answer:

a = 3, b = 4, c = 5

Step-by-step explanation:

Assuming we're working with a right triangle, where c is the hypotenuse, then using the definition of the cosine being the adjacent side over the hypotenuse, then we know:

a = 3, because it is the side adjacent to B

b = 4, because it is the side adjacent to A

c = 5, because it is the denominator in bot fractions

This of course assumes that there is no additional ratio in place.  For example, if the lengths were instead 8, 6 and 10 respectively, then the cosines given would still be 4/5 and 3/5.  Truthfully these only tell relative sizes of the sides, and not their absolute sizes.

Answer:

Distance = 8

Step-by-step explanation:

The length of the line between (8,6) and (8,-2) is 8.

The distance between (8, 6) and (8, -2) is 8 units.

Distance between two points is the length of the line segment that connects two given points.

[tex]d = \sqrt{(x_{2}-x_{1}) ^{2} +(y_{2} -y_{1}) ^{2} }[/tex]

According to the given question

We have two points

(8, 6) and (8, -2)

Let,

[tex](x_{1} ,y_{1} ) = (8,6)[/tex]

and, [tex](x_{2},y_{2}) =(8,-6)[/tex]

Therefore,

The total distance between (8, 6) and (8, -2)

[tex]=\sqrt{(8-8)^{2}+(-2-6)^{2} }[/tex]

[tex]=\sqrt{0+(-8)^{2} }[/tex]

[tex]=\sqrt{64}[/tex]

[tex]=8[/tex] unit

Hence, the distance between (8, 6) and (8, -2) is 8 units.

Answer:

The amount of 12% note is $90,000

The amount of 9% note is $80,000

Step-by-step explanation:

Missing word "The amount of the 12% note is $ and the amount of the 9% note is $"

Selling price = $170,000

Let x be the amount of money paid short term, therefore the amount of money paid long term is (170000 - x)

Given total annual interest = $18,000

Total annual interest = Interest due to short term (x) + interest due to long term (170000 - x)

18,000 = 0.12x + 0.09*(170000 - x)

18,000 = 0.12x + 15,300 - 0.09x

18,000 = 0.03x + 15,300

0.03x = 18,000 - 15,300

0.03x = 2,700

x = 2,700/0.03

x = 90,000

So, the amount of 12% note is $90,000

So long term paid money = $170,000 - $90,000 = $80,000

So, the amount of 9% note is $80,000

Answer:

(2v + 1)(t - 5)

Step-by-step explanation:

The first two terms of 2tv+t-10v-5 factor into t(2v + 1); the last two terms factor into -5(2v + 1).  Thus, (2v + 1) is a factor of 2tv+t-10v-5:

2tv+t-10v-5  = (2v + 1)(t - 5)

The required factors of 2tv+t-10v-5 to make k are (2v + 1) and (t -5).

Given that,
To factorize 2tv+t-10v-5 and make the k the subject.

Factors can be defined by splitting the value into multipliable values.

The process in mathematics to operate and interpret the function or expression to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here, according to the question to make k we have to factorize the  2tv+t-10v-5. So,

k = 2tv + t - 10v - 5
k = t( 2v + 1 ) - 5( 2v + 1 )
k = ( 2v + 1 ) ( t - 5 )

Thus, the required factors of 2tv+t-10v-5 to make k are (2v + 1) and (t -5).

Radius (r) = 7 feet

circumference (c) = ?

We know

C =2 πr

= 2 * 3.14 * 7

= 43.96 feet

Hope it will help :)

Answer:  43.96

==================================================

Work Shown:

C = 2*pi*r

C = 2*pi*7

C = 2*7*pi

C = 14pi ............. exact circumference in terms of pi

C = 14*3.14

C = 43.96

This value is approximate because pi = 3.14 is approximate.

Note: the circumference is the same as the perimeter of the circle. It's the distance around the circle's edge.

Answer:

32.6°F.

Step-by-step explanation:

The initial temperature of the water was 33.2°F. After several minutes, the temperature of the water changed by -0.6°F. So, the new temperature of the water is

33.2 + (-0.6)  

=  

(30 + 3) + [0.2 + (-0.6)]

=  

33 + (-0.4)

=  

33 – 0.4

=  

32.6°F.
