Answer:

6.5 cm

Step-by-step explanation:

The computation of the length of the apothem is shown below:

Given that

The side length is 9.4 centimeters

And, the radius is 8 centimeters

Now based on the above information

As per the attached figure  

AB = 8 cm

BC = 9.4 ÷ 2 = 4.7 cm

Now apply the pythagoras theorem

AB^2 = BC^2 + AC^2

8^2 = 4.7^2 + AC^2

AC^2 = 41.91

AC = 6.47 cm

= 6.5 cm

Answer: D). 6.5 cm

Step-by-step explanation:

Answer: B) 16 times 5/4

Step-by-step explanation:

16 divided by 4/5 = 20

16 x 5/4 = 20

When a whole number like 16 is divided by a fraction such as 4/5, you multiply it by the reciprocal (flipped version) of the fraction. What is the reciprocal of 4/5? It's 5/4. From there, you can solve each equation to make sure they are equivalent to check.

Answer:

404%

Step-by-step explanation:

To find the percentage difference do the following: (FV - SV)/|SV| * 100

(1260 - 250)/|250| * 100 {Subtract 250 from 1260 to get 1010. The absolute value of 250 is 250.}

1010/250 * 100 {Divide 1010 by 250 to get 4.04, or 101/25.}

101/25 * 100/1 {CROSS CANCELLATION}

101 * 4 {Multiply 4 by 101 to get 404.}

404%

The percent increase in the amount required to earn a credit over 38 years is 404%.

Answer:

Step-by-step explanation:

Cos(8x+21)=sin(-2x+51) Find the two angles represented in degrees ??? Someone help its 1am I can't do this

In trigonometry, cosx = sin(90-x)

Hence:

Cos(8x+21) = sin(90-(8x+21))

Cos(8x+21) = sin(90-8x-21)

Cos(8x+21) = sin(-8x+69)

Substituting into the expression given, :

sin(-8x+69) = sin(-2x+51)

-8x+69 = -2x+51

-8x+2x = 51-69.

-6x = -18.

X = 18/6

X = 3

Since the angles 8x+21

Angle = 8(3)+21

Angle = 45

The angles represented in degrees are 45 and (180-45) = 135degrees

Step-by-step explanation:

They all liked one type of food.

The percent of the students which does not like pizza, hamburgers or chicken in the result of survey of favorite food are 22%.

Percentage of a number is the part of the whole number which is expressed in the fraction of hundredth. It is represented with "%" symbol.

Students were surveyed about their favorite food. Here are the results:

The vann diagram which represent this result is attached below. 8% of the students like all three, so 4% like chicken and hamburger and 4% pizza and hamburger.

14% of the students like pizza and chicken. Thus, the percent of the students did not like pizza, hamburgers or chicken is,

Answer: a) There are 28 small  TV sets and 42 big TV sets

b) new Ratio of small and large TV set= 28:50

Step-by-step explanation:

Total stock of large and small TV=70

Ratio of small and large TV set=2:3

a) Total ratio=2+3=5

Small set=2/5 x 70= 28 small  TV sets

Big set=3/5 x 70 = 42 big TV sets

Step-by-step explanation:

In a triangle, all the angles must add up to 180. The angles in an equiangular triangle are all the same so you can just divide 180 by 3 to get one of the angles. This is equal to 60 degrees and since acute traingles have angles that are all less than 90 degrees, it is an acute triangle.

Answer:

[tex]y=-\frac{1}{4}x+40[/tex]

Step-by-step explanation:

Given

See attachment for graph

Required

Determine the equation of the line of best fit

First, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

From the graph, we can have:

[tex](x_1,y_1) = (20,35)[/tex]

[tex](x_2,y_2) = (60,25)[/tex]

So, the slope is:

[tex]m = \frac{25 -35}{60 - 20}[/tex]

[tex]m = \frac{-10}{40}[/tex]

[tex]m = -\frac{1}{4}[/tex]

The equation is then calculated as:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = -\frac{1}{4}(x - 20) + 35[/tex]

[tex]y = -\frac{1}{4}x + 5 + 35[/tex]

[tex]y=-\frac{1}{4}x+40[/tex]

Hence, the equation is: [tex]y=-\frac{1}{4}x+40[/tex]

Answer:

p = $340

Step-by-step explanation:

Let p represent the original price.  Then the amount Mary paid was (100% - 74%) of the original price:  0.26p = $88.40.

Solving for p:  p = $340

Check:  what is 74% of $340?  $251.60.  Subtracting this from $340, we get $88.40.  This agrees with the problem statement.

Answer: $1.62

Step-by-step explanation:

9% = 0.09

18 * 0.09 = 1.62

Answer:

1.62

Step-by-step explanation:

To find 9 percent of the number 18, we must create a proportion from which we can easily determine the value we are looking for.

First we create two simple equations with data that we know.

18 equals 100%, so we can save it as 18 = 100%

The value we are looking for can be called x

Now we know that x is 9 of the output value, so we can write it as x = 9.

So we have two simple equations:

1) 18 = 100%

2) x = 9%

When we compare these two equations, we get:

18 / x = (100%) / (9%)

Now we just have to solve the simple equation.

We calculate 9 percent of 18:

18 / x = 100/9

(18 / x) * x = (100/9) * x

18 = 11.111111111111 * x

18 / 11.111111111111 = x

1.62 = x

x = 1.62

Solution:

9 percent of 18 = 1.62

Answer:

we can conclude that there is significant evidence to support the stance that mean pH value in water differs from 8.5

Step-by-step explanation:

H0 : μ = 8.5

H1 : μ < 8.5

Test statistic :

(xbar - μ) / s/sqrt(n)

(8.24 - 8.5) ÷ (0.16 ÷ √12)

-0.26 ÷ 0.0461880

Test statistic = - 5.63

The Pvalue can be obtained from the test statistic value using a Pvalue calculator :

df = 12 - 1 = 11

Pvalue = 0.000077

Using an α value of 0.05 ; we can conclude that

Pvalue < α ; We reject H0

Hence, we can conclude that there is significant evidence to support the stance that mean pH value in water differs from 8.5

Answer: B = 50,000 * 1.18^t

Step-by-step explanation:

This requires the use of the Future Value formula.

Future value = Amount invested + ( 1 + rate) ^ number of years invested

Future value = B in this scenario.

t = number of years.

When putting in figures therefore, the formula becomes:

B = 50,000 * ( 1 + 18%) ^ t

B = 50,000 * 1.18^t

Answer:

15,17,19

Step-by-step explanation:

Here's your solution

=> let the first number be x

=> then second and third number will be

(x + 2) and (x + 4)

=> now it's given that sum is 51

=> so, x + (x + 2) + (x + 4) = 51

=> 3x + 6 = 51

=> 3x = 51 - 6

=> 3x = 45

=> x = 45/3

=> x = 15

hence ,the following number are , 15,17,19

Answer:

W = 6t + 90

Step-by-step explanation:

Given :

Starting weight = intercept = 90 kg

Weight gained after 8 months = 138 kg

Using the slope intercept relation ;

We can obtain the rate of change, slope ;

y = mt + c

m = slope ; t = time after t months ; c = intercept

y = weight gained after 8 months

138 = 8m + 90

138 - 90 = 8m

48 = 8m

m = 48 / 8

m = 6

Hence, slope intercept equation equals :

W = 6t + 90
