Answer:

180

Step-by-step explanation:

V=lwh

3=10·9·6

3=180

Answer:

If it is direct proportionality, then y = kx where k is a constant.  Use the given information to find k:

8 = k(12) ⇒ k = 8/12 = 2/3

y = (2/3) x

For y = 12,

12 = (2/3) x ⇒ x = (3/2)*12 = 18

x = 18 when y = 12

Answer:

7300    

  Step-by-step explanation:

I got it right  

Melanie would need to invest an amount of $7300.

Compound interest is defined as the amount of interest which has been calculated on the principal amount as well as the amount accumulated over the previous period is also included.

The final amount in a compound interest can be calculated using the formula,

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

Here A is the final amount, P is the principal value, r is the rate of interest, n is the number of times interest is compounded per year and t is the number of years.

Given,

A = $19,600

r = 5.2% = 5.2/100 = 0.052

Since it is compounded monthly, n = 12

t = 19 years

Substituting,

19,600 = P (1 + [tex]\frac{0.052}{12}[/tex])^ (12 × 19)

19,600 = P (1.0043)^(228)

19,600 = P (2.68)

P = 19,600 / 2.68

P = 7313.0767 ≈ 7300 to the nearest hundred

Hence the value of the account will reach $19,600 n 19 years if she invest an amount of $7300.

Answer:

x=24

Step-by-step explanation:

Hello There!

Angle E and angle D are supplementary angles meaning that the sum of the two angles equals 180

So we setup an equation

180=2x+12+5x

step 1 combine like terms

5x+2x=7x

now we have

180=7x+12

step 2 subtract 12 from each side

12-12 cancels out

180-12=168

now we have

168=7x

step 3 divide each side by 7

7x/7=x

168/7=24

we're left with~ x=24

Answer:

48

Step-by-step explanation:

288 divided by 6 is 48 and how you get mph is todal miles in 1 hr

The speed of the driver for the entire journey is 48 miles per hour.

The given parameters;

Speed is defined as the ratio of total distance traveled by the total time of motion.

The speed of the driver for the entire journey is calculated as follows;

[tex]speed = \frac{distance}{time} \\\\speed = \frac{288 \ miles}{6 \ hours} \\\\speed = 48 \ miles \ per \ hour[/tex]

Thus, the speed of the driver for the entire journey is 48 miles per hour.

Answer:

C. 4, 2, 1, 1/2, 1/4

Step-by-step explanation:

Geometric is normally either division or multiplication sequences. C has the division sequence of dividing by 2.

A would be an example of an arithmetic sequence.

The series 3, 6, 9, 12,... and  4, 2, 1, 1/2, 1/4 are geometric series.

Options A and C are the correct answer.

A geometric sequence is a sequence of numbers in which the ratio between consecutive terms is constant.

We have,

Looking at the options:

A.

3, 6, 9, 12,... is a geometric sequence with a common ratio of 2.

Each term is found by multiplying the previous term by 2.

B.

2, 3, 5, 9, 17 is not a geometric sequence because there is no constant ratio between terms.

C.

4, 2, 1, 1/2, 1/4 is a geometric sequence with a common ratio of 1/2.

Each term is found by multiplying the previous term by 1/2.

D.

3,-15, -33, -51, -69, is not a geometric sequence because there is no constant ratio between terms.

Therefore,

The series 3, 6, 9, 12,... and  4, 2, 1, 1/2, 1/4 are geometric series.
