Answer:

  a) V = 4w²h

  b) SA = 4w² +10wh

  c) SA = 4w² +37.5/w

  d) C = 40w² +225/w

Step-by-step explanation:

The relevant formulas are ...

  V = LWH

  base area = LW

  lateral area = H(2(L+W))

__

a) The length is 4 times the width, so the volume is ...

  V = (4w)(w)(h)

  V = 4w²h

__

b) The total surface area is the sum of the base area and the lateral area:

  SA = base area + lateral area

  SA = (4w)(w) + 2h(4w +w)

  SA = 4w² +10wh

__

c) The volume is 15 m³, so the height in meters in terms of the width in meters is ...

  15 = 4w²h

  h = 15/(4w²)

Then the surface area is ...

  SA = 4w² +10w(15/(4w²))

  SA = 4w² +37.5/w

__

d) The equation we have for surface area has one term for base area and a second term for lateral area. We can apply the cost factors to those terms to get the cost of materials:

  C = 10(4w²) +6(37.5/w)

  C = 40w² +225/w

This looks like a system of equations:

We should solve for c on the first equation because we can substitute for c. There are a lot of ways we can do a system of equations, but I will do this.

c - 3d = 11

  +3d     +3d

c = 11 +3d

Now we can substitute.

-2(11+3d) + 3d = -16

solve

-22 + -6d + 3d = -16

-22 + -3d = -16

+22             +22

-3d = 6

/-3     /-3

d = -2

So we have found d. We can solve for c.

c - 3(-2) = 11

c + 6 = 11

  -6      -6

c = 5

Now we know both D and C. d=-2 and c=5

Answer:

C=12.5

Step-by-step explanation:

you do 4x2 for 8 then you do 100/8 getting you 12.5

Answer:

1) m = 5

2) c = 12.5

Step-by-step explanation:

1) T = 2m + 30

T = 40

substitute for T

2m + 30 = 40

2m = 10

m = 5

2) A = 4bc

A = 100

b = 2

100 = 4(2)c

100 = 8c

c = 12.5

Answer:

The side of original square was 7.24 inches

Step-by-step explanation:

(x+3)(x+3) =2(x)(x)

x² + 6x + 9 = 2x²

reduce:

x² - 6x - 9 = 0

(x + 1.24)(x - 7.24) = 0

x = 7.24

Answer:      x=.7/2

Step-by-step explanation:

Answer: 0.151 percent

Step-by-step explanation:

The probability of any particular outcome is

   (number of possible successful outcomes) / (number of total possibilities)

-- On the first draw, there are 52 possible total outcomes, and

only 4 that are successful ... drawing a 3 .

The probability of drawing a 3 from a full deck is  ( 4 / 52 ).

-- On the second draw, there are 51 possible total outcomes (the first

card you drew stayed out), and only one is successful ... drawing the

queen of hearts.

The probability of this particular outcome is   ( 1 / 51 ).

-- The probability of both of them is  

                                ( 4 / 52 ) x ( 1 / 51 ) =

                                      ( 4 / 2,652 )  =  about 0.151 percent.

Answer:

I believe your answer is minimum

Answer:

x < -10

Step-by-step explanation:

Given the inequality 5 - 3x > 35

Subtract 5 from both sides

5 - 3x - 5> 35 -5

-3x > 30

Divide both sides by -3

-3x/-3 < 30/-3

x < -10 (note the change is sign)

hence the correct solution is x < -10

Answer: 6 hours and 30 min. or 6.5

Step-by-step explanation: divide 39 by 6 you get 6.5 then (.5) is actually going to be half an hour because half an hour is just 30 minutes

The number of hours Kristen worked each day is 6.5 hours.

Division is the process of determining the quotient of a number by grouping the number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations.

In order to determine this value, divide 39 by 6.

39 / 6 = 6.5 hours

Step-by-step explanation:

P^= 20/80=.25

sample size n= 80

z*=1.96

p^± sqr(p^(1-p^)/n)

=0.095

Step-by-step explanation:

The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is 0.25 +0.080.

Fatimah wants to estimate the proportion of students at her school who ate breakfast every day last week.

She takes an SRS of 80 of the 1000 students at her school and finds that 20 of those sampled ate breakfast every day last week.

Based on this sample, which of the following is a 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week?

She takes an SRS of 80 of the 1000 students at her school and finds that 20 of those sampled ate breakfast every day last week.

[tex]\rm P = \dfrac{Sample \ space}{Total \ SRS}\\ \\ P = \dfrac{20}{80}\\ \\ P = \dfrac{1}{4}\\ \\ P = 0.25[/tex]

Therefore,

The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is

=[tex] = 1.96 \times \sqrt{\dfrac{0.25(1-0.25)}{80}}\\ \\ = 1.96 \times \sqrt{\dfrac{0.25\times 0.75}{80}}\\\\ = 1.96 \times 0.40\\\\ = 0.080[/tex]

Hence, The 95% confidence interval for the proportion of all students at the school that ate breakfast every day last week is 0.25 +0.080.

Answer:

There are 8 more girls than boys.

Step-by-step explanation:

Ratios are easier to read as fractions (at least to me), so 5:7 would be 5/7. When you multiply both the top and the bottom by 4, you get 20/28, meaning that there are 20 boys and 28 girls. 28-20=8, so there are 8 more girls than boys.

Answer:

= 1.156 × 10^9

(scientific notation)

= 1.156e9

(scientific e notation)

= 1.156 × 10^9

(engineering notation)

(billion; prefix giga- (G))

= 1156000000

Step-by-step explanation:

Simply subtract A from B = 1,156,000,000 and convert the answer to scientific notation.

Answer:

D. 1.156 times 10^9

First we subtract the difference,

1,300,000,000 - 144,000,000 = 1156000000

Next, we find the number 1156000000 written in scientific notation.

Step 1

To find a, take the number and move a decimal place to the right one position.

Original Number: 115,600,000

New Number: 1.15600000

Step 2

Now, to find b, count how many places to the right of the decimal.

New Number: 1 . 1 5 6 0 0 0 0 0

Decimal Count:   1 2 3 4 5 6 7 8

There are 8 places to the right of the decimal place.

Step 3

Building upon what we know above, we can now reconstruct the number into scientific notation.

Remember, the notation is: a x 10b

a = 1.156 (Please notice any zeroes on the end have been removed)

b = 8

Now the whole thing:

1.156 x 108

Step 4

Check your work:

108 = 100,000,000 x 1.156 = 115,600,000

Thus, 115,600,000 written in scientific notation is 1.156 times 10^9 estimated.
