Zarea finds 3^√6000 and shows her work below. 3^√6000 = 3^√? x 3^√6 = 10 ^3√6 what is the missing value?

Answers

Answer:

  ? = 1000

Step-by-step explanation:

Zarea is making use of the fact that the cube root of a product is the product of the cube roots. She is factoring out the largest perfect cube in the number 6000.

  [tex]\displaystyle \sqrt[3]{6000}=\sqrt[3]{1000\cdot6}=\sqrt[3]{\boxed{1000}}\cdot\sqrt[3]{6}=10\sqrt[3]{6}[/tex]

Answers

Answer:

EI = 30

GH = 30

RS = 10

Step-by-step explanation:

Given:  PQRST ~ HGFEI

From inspection of the diagram, the corresponding sides are:

RS ~ FE

ST ~ EI

TP ~ IH

QP ~ GH

QR ~ GF

The only pair of sides that both have side lengths are QR and FG.  Therefore, we can use these to work out the scale factor of dilation.

QR = 8   and   GF = 20

⇒ GF/QR = 20/8 = 2.5

Therefore, HGFEI is an enlargement of PQRST by a scale factor of 2.5

If ST = 12,

⇒ EI = 12 x 2.5 = 30

If QP = 12,

⇒ GH = 12 x 2.5 = 30

If EF = 25,

⇒ RS = 25 / 2.5 = 10

If IH = 15,

⇒ TP = 15 / 2.5 = 6

Answer:

See below ~

Step-by-step explanation:

As they are similar, find the scale factor.

QR ~ GF8 : 202 : 5

Finding EI

ST ~ EIST : EI = 2 : 5EI = 5 x 12 / 2 EI = 30

Finding GH

QP : GH = 2 : 5GH = 5 x 12 / 2GH = 30

Finding RS

RS : FE = 2 : 5RS = 2 x 25 / 5RS = 10

At a local restaurant, the amount of time that customers have to wait for their food is normally distributed with a mean of 26 minutes and a standard deviation of 4 minutes. Using the empirical rule, determine the interval of minutes that the middle 95% of customers have to wait.

Answers

The middle 95% of customers have to wait for 18 to 34 minutes at the resturant.

What is the empirical rule?

The empirical rule states that for a normal distribution. 68% of the values are within one standard deviation from the mean, 95% of the values are within two standard deviation from the mean and 99.7% of the values are within three standard deviation from the mean

Given a mean of 26 minutes and a standard deviation of 4 minutes. Hence:

95% are within 2 standard deviations = 26 ± 2(4) = (18, 34)

The middle 95% of customers have to wait for 18 to 34 minutes at the resturant.

If a student wants to multiply by 8 they can?

A. Multiply by 2 three times
B Multiply by 2 four times
C Multiply by 4 twice
D Multiply 2 and multiply by 4 and add them together

Answers

The answer is A because 2^3 or 2x2x2=8. So if you multiply a number by 2 three times it would be the same as multiplying a number by 8.

Hello Brainly user,

A. Multiply by 2 three times if you want to multiply by 8.

Proof:

For example, if you want to multiply 2 by 8 --> 2x8  then you can just do 2x2 = 4  4x2 = 8  8x2 = 16.

TO CHECK:

You can do 8x2 = 16.

Hence, this answer is 100% correct.

OAB is a triangle
OA = 4a and OB = 5b
M is the midpoint of OB
AN:NB = 2:3
Find OP:PN

Answers

Answer:

5:2

Step-by-step explanation:

ON = OA + AN

AN = 2/5AB

AB = 5b-4a

AN = 2b - 8/5a

ON = 4a - 8/5a +2b

ON = 12/5a+2b

OP = k(12/5a+2b)

OP = OA + AP

AP = x(AM)

AM = 5/2b-4a

OP=4a-4ax+5/2bx

OP=4a-4ax+5/2bx and OP=12/5ak+2bk

Coefficients of A

4-4x=12/5k

k=(20-20x)/12

Coefficients of B

5/2x=2k

k=5/4x

(20-20x)/12 =5/4x

20=35x

x=4/7

k=5/4 * 4/7 = 5/7

OP=k(ON)

OP = 5/7

PN = 2/7

OP:PN = 5:2

Martin Office Supplies paid a $6 dividend last year. The dividend is expected to grow at a constant rate of 7 percent over the
next four years. The required rate of return is 20 percent (this will also serve as the discount rate in this problem). Use Appendix
B for an approximate answer but calculate your final answer using the formula and financial calculator methods.
a. Compute the anticipated value of the dividends for the next four years.
Anticipated Value
D1
D2
D3
D4

Answers

The anticipated value of the dividend in:

Year 1  is $45.86

Year 2 is  $49.07.

Year 3 is $52.50.

Year 4 is $56.18.

What is the anticipated value of the dividend?

The formula that can be used to determine the value of the dividend is:

Value = dividend paid last year x (1 + growth rate^number of years)  / (required return - growth rate)

D1 = ($6 x 1.07) / (20% - 7%) = $45.86

D2 = ($6 x 1.07²) / (20% - 7%) = $49.07

D3 = ($6 x 1.07³) / (20% - 7%) = $52.50

D4 = ($6 x 1.07^4) / (20% - 7%) = $56.18

You have:

[tex](x+5)^2+(y-1)^2=4^2[/tex]

To find the center of the circle, you want to find the 'x' and 'y' values which make their respective term equal zero:

[tex](y-1)^2=0[/tex]
