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

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

in mix number, the answer will be

[tex]8 \frac{7}{9} [/tex]

if you need in decimal form than the answer in going to be

[tex]8.777778[/tex]

Answer:

8[tex]\frac{7}{9}[/tex]

Not sure what you mean by "also you need to get a mic number for the end"

Answer:

Well 40% of 120 is 48 so 48 students

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:

The volume of the prism is [tex]1250cm^{3}[/tex]

Step-by-step explanation:

First let's get the area of the triangle. To get that, we use the formula [tex]\frac{bh}{2}[/tex]

In words, this is base · height ÷ 2

When we plug in the numbers, it is 10 · 10 ÷ 2, which is equal to 50.

And of course we multiply 50 by 25 to find [tex]1250cm^{3}[/tex]

Answer: m ≥ −5 pls give me brainliest

Step-by-step explanation: 9≥−2m+2−3

Subtract 3 from 2 to get −1.

9≥−2m−1

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

−2m−1≤9

Add 1 to both sides.

−2m≤9+1

Add 9 and 1 to get 10.

−2m≤10

Divide both sides by −2. Since −2 is negative, the inequality direction is changed.

m≥  

−2

10

​  

Divide 10 by −2 to get −5.

m≥−5

Answer:

45 and 135degrees

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:

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

b)f the number of large sets is increased by 8  then

Big set TV  = 42 + 8=50

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

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:

54.27333333

Step-by-step explanation:

just put them all into a calculator and multiply them

1/3*23.26*7=54.27333333

Answer:

around 54.27

Step-by-step explanation:

Just multiply the numbers or change them to decimals (1/3 = 0.333 , 23.26, and 7 = 7.0)

1/3 * 23.26 * 7 = 54.273 (repeating)

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:

[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]
