1 Billy is looking for a number between 3.6 and 4.05 for a homework problem. Which number could Billy use? a) 3.59 b) 3.79 c) 4.06 d) 4.50

Answer:

Step-by-step explanation:

42-42(2/7)

42-12

30

There are 30 options with no chocolate.

Isolate the variable, note the equal sign, what you do to one side, you do to the other.

1) 4k = 24

Isolate the variable, k. Divide 4 from both sides of the equation:

(4k)/4 = (24)/4

k = 24/4

k = 6

2) 34 + h = 60

Isolate the variable, h. Subtract 34 from both sides of the equation:

34 (-34) + h = 60 (-34)

h = 60 - 34

h = 26

3) 1/5x = 30

Isolate the variable, x. Multiply 5 to both sides of the equation:

(5) * (1/5)x = (30) * (5)

x = 30 * 5

x = 150

4) m - 42 = 85

Isolate the variable, m. Add 42 to both sides of the equation:

m- 42 (+42) = 85 (+42)

m = 85 + 42

m = 127

Answer:

An=67⋅0.92n

Step-by-step explanation:

The solution is, the formula found in the given question is ,

An=67. 0.92n.

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

At 12 p.m., the number of cars in a parking lot is 67.

It is estimated that the number of cars in the parking lot will decrease by 8% each hour.

so, we get,

Given,

at first the number of cars in a parking lot is = 67

now, it is decreasing by 8% each hour.

So, for any hours , let after 'n' hours,

the number will be = 67 * (100 - 8)%×n

                               =67 * 92%×n

                               = 67* 0.92n

Thus, The solution is, the formula found in the given question is ,

An=67. 0.92n.

Answer:  D) 2.33 meters

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

Explanation:

The hundredths digit is 1/10 of the tenths digit. Because of this, the tenths and hundredths digit must be the same digit.

Only choice D fits the description.

The digit in the tenths place represents the value 0.3

Taking 1/10th of this leads to (1/10)*0.3 = 0.1*0.3 = 0.03

So the hundredths place represents the value 0.03

Note that,

2 + 0.3 + 0.03 = 2.33 meters

Answer: The answer is the first choice that states “ASA”.

Step-by-step explanation: ASA means angle, side, angle. From T - Q in triangle STQ it goes from angle, side, angle. From P - M in triangle NPM it also goes from angle, side, angle.

Answer:

the woman has to live 1 mile from work to minimize the expenses

Step-by-step explanation:

Given the data in the question;

the distance within 9 miles ⇒ 0 < x > 9

Total costs Q = cx + 4c/( x + 1)

costs should be minimum  ⇒ dQ/dx = 0

⇒ d/dx [ cx + 4c/( x + 1) ] = 0

⇒ ( x + 1)² = 4

take square root of both side

√[ ( x + 1)² ] = √4

x + 1 = 2

x = 2 - 1

x = 1

Therefore, the woman has to live 1 mile from work to minimize the expenses

Answer:

I think it's 3. cuz 17 cannot be divided by 18

Answer:

b=5

Step-by-step explanation:

We need to isolate b by itself to find the value of b.

[tex]8b + 12 = 52[/tex]

Subtract 12 from both sides

[tex]8b = 40[/tex]

[tex]b = 5[/tex]

Answer: Its 28 in.^2

Step-by-step explanation: Just did it on I ready

The area of this face is,

⇒ 28 in²

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

This face made by three rectangles.

Now,

The area of small rectangle = 4 × 2 = 8 in²

And, The area of large rectangle = 6 × 2 = 12 in²

Hence, The area of this face is,

⇒ 8 + 12 + 12

⇒ 28 in²

Thus, The area of this face is,

⇒ 28 in²

Answer:

let's divide the figure in rectangle and triangle.

first we should find the area of triangle.

area of triangle =1/2×base×height

area of triangle=1/2×11cm×7cm

area of triangle=38.5cm²

area of rectangle =length ×width

area of rectangle =11cm×8cm

area of rectangle =88cm²

area of the figure=38.5cm²+88cm²

area of the figure=126.5cm²

Answer:

  a[n] = (-1/3)^(n -1)

Step-by-step explanation:

The terms have a common ratio of (-1/3)/(1) = -1/3. The general term for a geometric sequence with first term a1 and common ratio r is ...

  a[n] = a[1]×r^(n-1)

Here, a[1] = 1, so this is ...

  a[n] = (-1/3)^(n-1)

Answer:

x=7.5

Step-by-step explanation:

To show that the triangles are similar, we simply need to show that all sides are proportionate.

So,  we create a proportion

[tex]\frac{FE}{ZY} =\frac{ED}{XY} = \frac{FD}{XZ}[/tex]

Then we plug in the values

[tex]\frac{6}{12} = \frac{7}{14} = \frac{2x-5}{22}[/tex]

[tex]\frac{6}{12}[/tex] and [tex]\frac{7}{14}[/tex] can be simplified to [tex]\frac{1}{2}[/tex], so that is our ratio of similarity

then we know

[tex]\frac{1}{2} = \frac{2x-5}{22}[/tex]

Now solve

1. Cross multiply

2×(2x-5) = 22

2. Distribute

4x-8 = 22

4x=30

x=7.5

There is your answer, x=7.5

Answer:

Step-by-step explanation:

Explicit

a_n = a1 * r^(n - 1)

Find r by dividing term (n)/(n - 1)

r = 250 / 50

r = 5

a_n = a * r^(n - 1)

Recursive

a_n = a_(n-1)*r

Try an example

Find a_6

a_6 = 2 * 5^(6 - 1)

a_6 = 2 * 5^5

a_6 = 2 * 3125

a_6 = 6250

recursive

a_n = a_(n - 1)*r

r = 5

n = 6

a_n = 1250 * 5

a_n = 6250

The explicit method looks a whole lot easier, but not for a machine made by Dell and programed by Microsoft. A computer doesn't really mind doing a whole lot of calculations that are repetitive. And in many cases recursive is easier to program and is faster.

Answer:

Step-by-step explanation:

The given sequence is exponential with a first term of a1 = 2 and a common ratio of r = 10/2 = 5.

The explicit equation for an exponential sequence is ...

  a(n) = a(1)×r^(n -1)

So, for the given parameters, the explicit equation is ...

  a(n) = 2×5^(n -1)

__

The recursive equation for any series defines the next term as a function of previous terms. For a geometric sequence the next term is the previous term multiplied by the common ratio. For this sequence, the recursive definition is ...

  a(1) = 2

  a(n) = 5×a(n-1)
