solve ??? If any1 can

Answer:

Step-by-step explanation:

in this problem we are expected to solve for the diameter of each circle pendant and add them to get the height of the complete pendant.

we know that the circumference is given as

C=πd

for the small circle

C=6cm

6=3.142d

d=6/3.142

d=1.9cm

for the big circle

C=8cm

8=3.142d

d=8/3.142

d=2.5cm

the height then is 1.9+2.5=4.4cm

Answer:

6.333

Step-by-step explanation:

Our triangle vertices are

(1,1)(5,1)(2,9)

We are to perform interpolation at point(3,5)

x and y values are interpolated

On vertices (5,1)(2,9)

x = 3

x1 = 5

X2 = 2

Y1 = 1

Y2 = 9

Formula for interpolation

Y = [y1+(x-x1)(y2-y1)]/x2-x

Y = 1+(3-5)(9-1)/2-5

Y = 1+[-2*8/-3]

Y = 1+16/3

From here we use use LCM to get:

19/3 = 6.333

Answer:

2.370

Step-by-step explanation:

In this, the word "and" means the decimal point so:

two and 3

=

2.3

so the tenths place would be the first number after the decimal point, you can think of it as counting backwards. 1000  100  10  "0"  0.1  0.01  0.001

                                                thousnd hundrd tn zro tnths hundrds thousndths

so the 3 hundred would be 0.3 and the sevenTY thousandths would be 0.070

so add that all up and you get:

2.370

or

two and three hundreds seventy thousandths

Hope this helped! Pls Brainliest! It would help and mean a lot! ; )

Answer:  3/11

Step-by-step explanation:

you must do cross canceling to simplify the expression

then just do multiplication from left to right

7/11 times 3/7 the 7 can be crossed out and turned into a 1

then do 1 times 3 for the numerator then 11 times 1 for the denominator and get you answer 3/11

Answer:

There are 12 left-handed players in the league

Step-by-step explanation:

Let us solve the problem

∵ A local little league has a total of 60 players

∵ 20% of them are left-handed

→ Find 20% of 60

∴ The number of left-handed players = 20% × 60

→ Change 20% to a decimal

∵ 20% = [tex]\frac{20}{100}[/tex] = 0.20

∴ The number of left-handed players = 0.20 × 60

∴ The number of left-handed players = 12

∴ There are 12 left-handed players in the league

Answer:

Before her donation, Marie owned 35 comic books.

Step-by-step explanation:

Marie donated 40% of her comic books to a school, that is, Marie donated 40 comic books per 100 comic books she owned. We can write it as a ratio: the ratio of donated comic books to total comic books is 100:40. If she donated 14 comic books, the number of comic books she owned before her donation were:

14 donated cb × (100 total cb/40 donated cb) = 35 total cb

Answer:

The input value is -2

Step-by-step explanation:

Input values are x-values plotted on the horizontal axis (x-axis) while the output values are plotted on the vertical axis (y-axis).

What we are simply asked to do is to determine what the value of x is on the x-axis, that corresponds to the y-value of 2 on the y-axis.

Thus, when y = 2 on the x-axis, x = -2 on the x-axis.

The input value of -2, corresponds to the output value of 2.

Answer:

-2

Step-by-step explanation:

Input values are x-values plotted on the horizontal axis (x-axis) while the output values are plotted on the vertical axis (y-axis).

We are expected to determine what the value of x is on the x-axis, that corresponds to the y-value of 2 on the y-axis.

When y = 2 on the x-axis, x = -2 on the x-axis.

The input value of -2, corresponds to the output value of 2.

True.

When you break it down, it's 0.45 compared to 0.50, so 0.5 is greater than 0.45 by 0.05. Also, 0.5 is closer to 0.

Answer:

C

Step-by-step explanation:

It's another way of saying where the lines cross. So if the input value (x) = 1 then both lines have an output value of 1.

The fish tank problem:

x = # of days

180 - 8x = 160 - 6x

Add 8x to both sides and subtract 160 from both sides.

20 = 2x

Divide both sides by 2

10 = x

It will take 10 days for the fish tanks to have the same amount of water in them.

The sand castle problem:

x = # of minutes.

180 - 8x = 160 + 6x

Add 8x to both sides and subtract 160 from both sides.

20 = 14x

Divide both sides by 14

x = 10/7 mins

After 10/7 mins their sand castles will be the same height

Answer:

The 90% confidence interval is  [tex] 2.47<\mu < 2.59 [/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  6

   The sample mean is  [tex]\= x = 2.53 \ mm[/tex]

   The standard deviation is  [tex]\sigma  =  0.090\ mm[/tex]

Given that the confidence level is 90% then the level of significance is  

        [tex]\alpha =  (100 - 90)\%[/tex]

=>     [tex]\alpha =  0.10 [/tex]

Generally from the normal distribution table the critical value  of  [tex]\frac{\alpha }{2}[/tex] is  

   [tex]Z_{\frac{\alpha }{2} } =  1.645 [/tex]

Generally the margin of error is mathematically represented as  

      [tex]E =1.645 *  \frac{0.090 }{\sqrt{6} }[/tex]

=>   [tex]E = 0.060 [/tex]

Generally 90% confidence interval is mathematically represented as  

      [tex]\= x -E <  \mu <  \=x  +E[/tex]

      [tex]2.53  -0.060 <\mu < 2.53  + 0.060[/tex]

=>   [tex] 2.47<\mu < 2.59 [/tex]

Answer:

Step-by-step explanation:

Find the question attached.

Given the zero of the polynomial 5+3i and 0, this means that (x-0) and (x-(5+3i)) are factors

Multiplying the factors together we have;

= x((x-(5+3i))

= x(x-5-3i)

= x²-5x-3xi

Hence the polynomial expression of the zeros is x²-5x-3xi

Answer:

There's a proportion relationship between number of shell and their cost

Step-by-step explanation:

The graph is not given.

However, I've added the appropriate graph as an attachment.

From this, point....

I'll show that the cost and number of shells as given in the question are proportional.

Represent cost with y and number of shells with x

x = 2 when y = 0.8

x = 3 when y = 1.2

x = 4 when y = 1.6

Divide each value of y by x to get the constant of proportion (r).

r = y/x

r = 0.8/2 = 0.4

r = 1.2/3 = 0.4

r = 1.6/4 = 0.4

Notice that the values of r remain constant.

Hence, there's a proportion relationship between both

And what this rate represent is that:.the cost of shell changes at a constant rate when the number of shell is changes.

The proportionality constant is same means that the cost of shell changes at a constant rate when the number of shells changes.

Given :

The following steps can be used to determine there is a proportional relationship or not between the number of shells and their cost:

Step 1 - First determine the value of x and y from the given data.

Points - (2,0.8), (3,1.2), and (4,1.6)

Step 2 - Now, divide y by x in order to determine the proportionality constant.

[tex]r = \dfrac{0.8}{2} = 0.4[/tex]

[tex]r'=\dfrac{1.2}{3}=0.4[/tex]

[tex]r" =\dfrac{1.6}{4}=0.4[/tex]

Step 3 - Observe that the values of r, r', and r" are the same. Therefore, there is a proportional relation between them.

The proportionality constant is same means that the cost of shell changes at a constant rate when the number of shells changes.

Step-by-step explanation:

Computation for the break-even in sales dollars for Division Q

First step is to compute the Segment Contribution Margin ratio

Using this formula

Segment Contribution Margin ratio = Segment contribution margin ÷ Segment sales

Let plug in the formula

Segment Contribution Margin ratio= $ 175,980÷ $ 419,000

Segment Contribution Margin ratio= 0.42

Last step is to find the break-even in sales dollars for Division Q using this formula

Break-even in sales dollars = Segment traceable fixed expenses ÷ Segment Contribution Margin ratio

Let plug in the formula

Break-even in sales dollars= $85,400÷ 0.42

Break-even in sales dollars=$203,333

Therefore the break-even in sales dollars for Division Q is $203,333
