Answer:

Bill by $85

Step-by-step explanation:

Bill :  Compound interest is calculated by multiplying the initial principal amount by one plus the annual interest rate raised to the number of compound periods minus one. The total initial amount of the money given  is then subtracted from the resulting value.

Compounded annually for 6 years at 9 % interest Bill would have $8385.50.

Joe : Simple interest at 11% a year The formula we'll use for this is the simple interest formula.

P is the principal amount, $5000.00.

r is the interest rate, 11% per year, or in decimal form, 11/100=0.11.

t is the time involved, 6year(s) time periods.

So, t is 6year time periods.

To find the simple interest, we multiply 5000 × 11 × 6  = 3300

Usually now, the interest is added onto the principal to figure some new amount after 6 year(s),

or 5000.00 + 3300.00 = 8300.00

As you can see Bill has more by $85.

Answer:

2.5

Step-by-step explanation:

Divide each side by 1.6 to get m alone, thus getting the answer, so 1.6m/1.6 and 40/1.6

The solution of the equation 40 = 1.6 m is m is equals to 25.

Given Equation:

40 = 1.6m

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

First, write the decimal 1.6 in fraction as 16/10.

So, the equation can be written as

40 = 16/10 (m)

40 x 10 = 16m

400 = 16 m

Now, divide both side of equation by 16

400/ 16= 16 m/ 16

25 = m

Therefore, the value of m is 25.

Which inequality is true if p = 2.8?

3p < 10.2

13.6 ≤ 3.9p

5p > 17.1

8.5 ≥ 2.5p

Answer:

3p < 10.2

8.5 ≥ 2.5p

Step-by-step explanation:

To obtain the true expression, put p = 2.8 in all the options and choose the true inequality expression :

3(2.8) < 10.2

8.4 < 10.2 ( true)

13.6 ≤ 3.9p

13.6 ≤ 3.9(2.8)

13.6 ≤ 10.92 ( False)

5p > 17.1

5(2.8) > 17.1

14 > 17.1 ( False)

8.5 ≥ 2.5p

8.5 ≥ 2.5(2.8)

8.5 ≥ 7 (True)

Answer:

The measure of an exterior angle is found by the following formula: Aˆ0B=^AB-^CD2. An interior angle has its vertex at the intersection of two lines that intersect inside a circle. The sides of the angle lie on the intersecting lines. You can find a measure of an exterior angle of a regular polygon with  

N  sides.  It is equal to   360 o N .

Step-by-step explanation:  

Angles of a general polygon (exterior and interior) with more than 3 sides are not defined by the lengths of its sides.  

However, we can calculate the sum of all interior or exterior angles of any convex polygon. It equals to  360 o .

It can be proven geometrically since each exterior angle describes a rotation by some angle and a sum of all exterior angles describes a rotation by full angle of  

360 o . So, if all exterior angles are equal, like in a regular polygon, each one equals to  360 o N .

It can also be defined with some algebraic calculations based on the fact that a sum of all interior angles is  ( N − 2 ) ⋅ 180 o .  

Dividing the above by  N

we will obtain a value of an interior angle:  ( N − 2 ) ⋅ 180o N .  

Therefore, exterior angle of a regular polygon is  180 o − ( N − 2 ) ⋅ 180 o N = 360 o N

How many gallons does it take to cover 1/7 of the fence?

1 1/8 divided by 3= 9/8 divided by 3/1  or 9/8*1/3=9/24 or 3/8.

It takes 3/8 of a gallon to paint 1/7 of a fence.

7*3/8= 7/1*3/8= 21/8.

I believe your answer is: it takes 21/8 or 2 5/8 gallons of paint to paint the whole fence.

Answer:

$34.83

Step-by-step explanation:

First convert 3/4 to decimal form: 3/4 = 0.75

Create a proportion using similar rates:

$2.75 / 0.75 lb  = x / 9.5 lb

where "x" represents the price of the 9.5 lbs of grapes we need to find.

Solve for x by multiplying both sides by 9.5 lb to isolate x completely

2.75 * 9.5 / 0.75 = x

Therefore x = $34.83

Answer:Median = Mid value of Set of observation

If number of observation is odd, suppose n

Median =  th term

If number of observation is even , then

Median = Mean of two middle observation i.e

Data set : 17, 20, 30, 28, 18

Data arranged in ascending order: 17,18,20,28,30

Let one data =x

Number of observation is even.

Given, Median = 24

As , when number of observation is even , median is mean of two mid values.

Median=→→→ getting the median.

So, x must be greater than 30.

The correct option satisfying the above condition is Option (D) 34.

Answer:

A. The missing number is 11

Step-by-step explanation:

The highest number in the set is 30 and the lowest is 12, this makes the range 18.

30 is supposted to be there to make the range what the problem says it is: 12.

20 and 25 could be there because no matter what, as long as 30 is the greatest number, 20 and 25 don't effect the range AT ALL.

If 11 was in the number sequence, the lowest number would be 11, making the range 19, (30-11=19) which is not what the teacher is saying the range is.

So in short, A. The missing number is 11 is the correct answer.

Answer:

15/8

Step-by-step explanation:

Literally find the common denomiator. That's the first step for any of these computational fraction problems.

Here are the following denomiators: 4,8,3,6. You notice that 24 is a multiple of all the numbers. Thus, our common denomiator is 24. Next we change each fraction based on our new denomiator

3/4 = 18/24

5/8 = 15/24

2/3 = 16/24

1/6 = 4/24

Now we do basic computation

18/24 + 15/24 + 16/24 - 4/24 = 45/24 = 15/8

Step-by-step explanation:

The required ratio of the number of triangles to the number of circles is 3:5.

Given that,
There are 15 circles and 9 triangles. What is the simplest ratio of triangles to circles is to be determined.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

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

Here,
Number of circles = 15
Number of triangles = 9
The ratio of the triangle to the circle,
= Number of triangles / Number of circles
= 9 /15
= 3 / 5

Thus, the required ratio of the number of triangles to the number of circles is 3:5.
