Answer:

20.283

Step-by-step explanation:

1) the formula of the required Area is:

A=A₁+A₂, where A₁ - area of semicircle, A₂ - area of rectangular;

2) the radius of the semicircle is: r=(7-2-1)/2=2 cm, then the area A₁:

A₁=0.5*π*r²=2π≈6.283 (cm²);

3) A₂=7*2=14 (cm²);

4) finally, A=A₁+A₂=6.283+14=20.283 (cm²)

Answer:

31

Step-by-step explanation:

The linear equaiton is 3p + 2 = 11.Then the number of plants that fit on each shelf will be 3.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

Ana wants to place 11 plants on 3 shelves each shelf holds the same number of plants there are two plants that do not fit.

Let 'p' be the number of plants in a row. Then the equation is given as,

3p + 2 = 11

Simplify the equation, then we have

3p + 2 = 11

3p = 11 - 2

3p = 9

p = 9 / 3

p = 3

The linear equaiton is 3p + 2 = 11.Then the number of plants that fit on each shelf will be 3.

Step-by-step explanation:

Required

15 is what percentage of 105

To do this, simply divide 15 by 105 multiplied by 100%.

So, we have:

[tex]\%Percent = \frac{15}{105} * 100\%[/tex]

[tex]\%Percent = \frac{15*100}{105}\%[/tex]

[tex]\%Percent = \frac{1500}{105}\%[/tex]

Answer:

False

Step-by-step explanation:

The answer to this question is false because the missing observation does not introduce bias to the estimator. But missing observations reduces the size of the sample that is available from the given population. Therefore reducing the precision of the estimators.

In conclusion, no bias is introduced because of missing observations so the answer is false.

Answer:

13/6 Which you can divide and get a decimal instead (Decimal: 2.166667)

Step-by-step explanation:

Answer:

a) 92.9 degrees

b) 20 degrees

Step-by-step explanation:

Using the conversion factor;

180 degrees = pi radians

For 1.62 radians;

1.62 radians = x

pi radians = 180 degrees

Divide both expressions;

1.62/pi = x/180

pi * x = 1.62 * 180

pi * x = 291.6

x = 291.6/pi

x = 291.6/3.14

x = 92.9 degrees

Hence 1.62 radians is equivalent to 92.9 degrees

b) Recall that

pi radians = 180 degrees

pi/9 rad = y

Cross multiply

y * pi = 180pi/9

y = 180/9

y = 20 degrees

Hence pi/9 radians is equivalent to 20 degrees

Answer:

B

Answer:

Step-by-step explanation:

I understand why this was kind tough

the slope of line d is infinite  and the slope of line c is zero

so line c 's  equation looks like  y = 3  ... it's kinda  confusing but  the line is always 3  so you could pick any x value and y = 3 still.  the equation y=3 doesn't rely on x at all to answer it.    But x is part of the "frame work" that is implied.    

line d  is  x = 3   , again , y is part of the "frame work" and implied that y doesn't matter in this equations, you always have x = 3 .. or a vertical line , btw. line d does NOT pass the vertical line test , and therefore isn't a function,  so the question is wrong, that d will have an equation,  b/c there is an implication that d is a function when you say "what is the equation to line d" that is must be a function. But in this case it's not.   hm :/  food for thought

Answer:

  x = 8.2

Step-by-step explanation:

As indicated on the supplied diagram, the measure of arc GH is ...

  GH = 360° -83° -115° = 162°

The inscribed angle at F is half this measure, so we have ...

  (10x -1)° = 162°/2

  10x = 82 . . . . . . . . add 1 and simplify

  x = 8.2 . . . . . . . . . divide by 10

Answer:[tex]g (f (x)) = 3^{2} + 24[/tex]

Step-by-step explanation:

The true about the solutions of the equation f(x) = g(x) is

The solution of the graph where the graph of function intersect at

x = 1 and x = 3.642.

A mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).

We have function,

f(x) = log(x - 1)

g(x) = 1/3x² - 4

As, f(x) = g(x)

log (x-1) = 1/3 x² - 4

Now, putting x= 1, x= 3.642, x= 4.464, x= 4 , x= 0.422 into the formula for the observation.

So, the solution of the graph where the graph of function intersect at

x = 1 and x = 3.642

Answer:

A) The multiplier for this situation is 0.02.

B) The cost in 4 years will be $ 33,555.39.

C) 31,000 x 1.02 ^ N = X

Step-by-step explanation:

Since in 2012 the average cost for a new midsized car was about $ 31,000, and new car prices tend to go up about 2% every year, to determine what is the multiplier for this situation, what will the cost be in 4 years if this trend continues and to write an equation to calculate the cost in n years the following calculations must be performed:

A)

31,000 x 2/100 = X

31,000 x 0.02 = X

Thus, the multiplier for this situation is 0.02.

B)

31,000 x 1.02 ^ 4 = X

33,555.39 = X

Thus, the cost in 4 years will be $ 33,555.39.

C)

31,000 x 1.02 ^ N = X

Here, N represents the number of years over which the price increase will be calculated, and X represents the price after that number of years.

Answer:

Bailey's balance after 180 days is $ 157.39.

Step-by-step explanation:

Since Bailey wanted a new pair of shoes, and she put the $ 142 cost on her credit card, but because Bailey has been irresponsible with her credit, the credit card company charges her 22% annual interest, for figure Bailey's balance after 180 days, assuming she made no payments, the following calculation must be made:

365 = 100

180 = X

180 x 100/365 = X

18,000 / 365 = X

49.31 = X

22 x 0.4931 = 10.84

142 x 1.1084 = X

157.39 = X

Thus, Bailey's balance after 180 days is $ 157.39.
