What is the volume, in cubic feet, of this composite figure?

9514 1404 393

Answer:

  (x, y) = (0, 4)

Step-by-step explanation:

Since we have an expression for x, substitution works nicely.

  (8 -2y) +3y = 12 . . . . . . use the first equation to substitute for x in the 2nd

  y = 4 . . . . . . . . . . . . subtract 8, collect terms

  x = 8 -2(4) = 0 . . . . substitute for y in the first equation

The solution is (x, y) = (0, 4).

The volume of the aquarium is   6480 [tex]in. ^{3}[/tex]

A rectangular prism is a prism whose bases (the top face and the bottom face) are also rectangles. It has 6 faces in all, out of which there are 3 pairs of identical opposite faces, i.e., all the opposite faces are identical in a rectangular prism. It has three dimensions, length, width, and height.

The volume of a rectangular prism is the space that is inside it .

The volume of the rectangular prism, V = Length * Breath * Height

According to the question

Length of the aquarium = 36 in.

Breath of the aquarium = 12 in.

Height of the aquarium = 15 in.

As aquarium is a rectangular prism

volume of the aquarium,  = Length * Breath * Height

                                                            =   36 * 15 * 12

                                                            =    6480 [tex]in. ^{3}[/tex]

Hence, The volume of the aquarium is   6480 [tex]in. ^{3}[/tex]

Answer:

H0 : μ = 4.50

H1 : μ > 4.50

Test statistic = 1.525

we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.

Step-by-step explanation:

H0 : μ = 4.50

H1 : μ > 4.50

Test statistic :

(xbar - μ) ÷ s/sqrt(n)

(4.94 - 4.50) ÷ 2.10/ sqrt(53)

0.44 / 2.10/ sqrt(53)

= 1.525

α = 1 - 98% = 0.02

Decision region :

Reject H0 ; if Pvalue < α

Pvalue = p(Z < 1.525) = 0.936

Pvalue = 0.936

Since Pvalue > α ; We fail to reject H0

Hence, we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.

Answer:

C. Addition Property of Equality

Step-by-step explanation:

Given,

x - 6 = 4

To find x, the addition property of equality is applied by adding 6 to both sides.

Thus:

x - 6 + 6 = 4 + 6

x = 10

Answer:

Step-by-step explanation:

Given data

P=$4,250

Rate= 5.25%

Time= t years

1. The compound interest expression is

A=4250(1+0.0525)^t

A=4250(1.0525)^t

2. P=$4,250

Rate= 5.25%

Time= 5 years

1. The compound interest expression is

A=4250(1+0.0525)^5

A=4250(1.0525)^5

A=4250*1.2915

A=$5488.875

3. P=$4,250

Rate= 5.25%

Time= 10years

1. The compound interest expression is

A=4250(1+0.0525)^10

A=4250(1.0525)^10

A=4250*1.6680

A=$7089

Answer:

C

Step-by-step explanation:

So you can use two points on the line to find the gradient. I used K and G. B and D could've been easily eliminated since the line goes through the origin (0,0) so there's no y - intercept or b value.

M = (Y-y)/(X-x)

M = (8-4)/(14-7)

M = 4/7

And the equation of a line is y = mx + b. There's no b so it's just y = (4/7)x

Answer:

The speed of the current is 3 miles per hour

Step-by-step explanation:

The equations for rate (r), distance (d), and time (t) are ⇒ d = rt, r = d/t, = t = d/r

Let x = speed in still water

Let c = speed of the current

The main difference with these problems is rate needs to be expressed using two variables  because moving upstream the current is against you and downstream it moves with you.

Distance Rate Time

Upstream x − c

Downstream x + c

The distance column with the numbers from the problem and the value for speed in  still water for x.

Distance Rate Time

Upstream 4 5 − c

Downstream 16 5 + c

The column for time using the other two columns knowing that  rate,  distance  ⇒ time =  Distance Rate Time

Upstream 4 5 − c

5 − c

4

Downstream 16 5 + c

5 + c

16

“It takes as long …” from the problem means that the two times are equal to each other.  So, the equation can be written as:

4/5− c = 16/5 + c  ⇒ Solve by cross-multiplying ⇒ 5(4 + c) = 16 5( − c) ⇒ c = 3

Answer:

The value of the acount after t years is of [tex]A(t) = 650(1.0072)^{12t}[/tex]

The annual growth rate is of 0.72%.

Step-by-step explanation:

Compound interest:

The compound interest formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.

$650 is invested in an account earning 8.6% interest (APR), compounded monthly.

This means that [tex]P = 650, r = 0.086, n = 12[/tex]. So

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]A(t) = 650(1 + \frac{0.086}{12})^{12t}[/tex]

[tex]A(t) = 650(1.0072)^{12t}[/tex]

The value of the acount after t years is of [tex]A(t) = 650(1.0072)^{12t}[/tex]

Annual growth rate

1.0072 - 1 = 0.0072 = 0.72%

The annual growth rate is of 0.72%.
