A coat usually sells for $62.95. It is on sale for 10% off.
What is the sale price?

Answer:

7,000

Step-by-step explanation:

Answer: 2285.71

Step-by-step explanation:

Rearranging the simple interest formula, we have P = A / (1 + rt), where P is the Principal, r is the annaul rate and t is the time period.

r = R/100 = 5%/100 = 0.05 per year.

Solving the equation:

P = 3200 / ( 1 + (0.05 × 8)) = 2285.7142857143

Answer:

Grandma deposited 8,000

Step-by-step explanation:

I = 3200

r = 5 %

t = 8 years

[tex]P =\dfrac{I*100}{r*t}\\\\P = \dfrac{3200*100}{8*5}\\\\P= 8000[/tex]

We have that  the fourth term of an arithmetic sequence is

a_4=14

Option C

From the question we are told

What is the fourth term of an arithmetic sequence whose first term is 23 and whose seventh term is 5?

A) 78

B) 32

C) 14

(Explain your work)

Generally the equation for the  arithmetic sequence  is mathematically given as

[tex]a_4=a_1+(n-1)d[/tex]

Therefore

For seventh term

[tex]5=23+(6)d\\\\d=5-23/(6)\\\\d=-3[/tex]

Therefore

For Fourth term

[tex]a_4=23+(3*(-3))[/tex]

a_4=14

Answer:

2/3 divdied by 1/8 is 5 1/3

Step-by-step explanation:

You first keep the 2/3, change the operation to multiplication, then flip the 1/8 to 8/1, then multiply across to get 16/3. After that, simplify to get 5 1/3

Answer:

28 cents.

Step-by-step explanation:

There are 4 cups in 1 quart. So, 4 quarts is 16 cups.

If 4 quarts costs $4.48, to find the price per cup, you need to divide $4.48 by 16.

4.48 ÷ 16 = 0.28

This means each cup is 28 cents.

I hope this helps! :)

Step-by-step explanation:

you devide 4.48by 16 and your answer is 0.28

Answer:

18/45

Step-by-step explanation:

First you set 2/5 equal to x/45.

Then you see what number you need to multiply 5 by to get 45

Multiply 2 by the number you got and you get x.

The equivalent fraction for 2/5 with a denominator of 45 is 18/45.

We need to figure out what number we can multiply the numerator and denominator by to get the necessary denominator in order to discover an equivalent fraction for 2/5 with a denominator of 45.

The denominator must be multiplied by 9 in order to be converted from 5 to 45 (45 ÷ 5 = 9). To keep the ratio and get the equal fraction, we will also multiply the numerator by 9.

2/5 x 9/9 = (2 x 9) / (5 x 9) = 18/45

As a result, 18/45 is the corresponding fraction for 2/5 with a denominator of 45.

Answer:

19.7

Step-by-step explanation:

Using polar/cylindrical coordinates, we take

x = r cos(t )

y = r sin(t )

z = z

so that

dV = dx dy dz = r dr dt dz

The solid is given by the set

D = {(x, y, z) : x ² + y ² ≤ 1 and 0 ≤ z ≤ 4 - 2x - y}

or in cylindrical coordinates,

D = {(r, t, z) : 0 ≤ r ≤ 1, 0 ≤ t ≤ 2π, and 0 ≤ z ≤ 4 - 2r cos(t ) - r sin(t )}

Then the volume of the solid is

[tex]\displaystyle \iiint_D \mathrm dV = \iiint_Dr\,\mathrm dr\,\mathrm dt\,\mathrm dz \\\\ = \int_0^{2\pi} \int_0^1 \int_0^{4-2r\cos(t)-r\sin(t)} r\,\mathrm dz\,\mathrm dr\,\mathrm d t \\\\ = \int_0^{2\pi}\int_0^1 (4r-2r^2\cos(t)-r^2\sin(t))\,\mathrm dr\,\mathrm dt \\\\ = \int_0^{2\pi} \left(2 - \frac23 \cos(t) - \frac13 \sin(t)\right) \,\mathrm dt \\\\ = \boxed{4\pi}[/tex]

The volume of the given solid below the plane 2x + y + z = 4 and above the disk x2 + y2 ≤ 1 is 4π.

The volume of the solid in polar coordinates can be calculated by the double integral in polar coordinates.

[tex]V = \iint_R f(x,y) \,dA.\\[/tex]

Similarly, by polar coordinates,

x = r cost

y = r sint

z = z

we get, dV = dx dy dz = r dr dt dz

The solid is given

D = {(x, y, z) : x ² + y ² ≤ 1 and 0 ≤ z ≤ 4 - 2x - y}

or in polar coordinates,

D = {(r, t, z) : 0 ≤ r ≤ 1, 0 ≤ t ≤ 2π, and 0 ≤ z ≤ 4 - 2r cos(t ) - r sin(t )}

The volume of the solid is

[tex]\rm \int \int\int\ dV = \int \int\int\ rdr dt dz\\ \rm = \int\limits^{2\pi}_0\int\limits^1_0 \int\limits^{4-2rcost-rsint}_0 rdr dt dz\\\rm =\int\limits^{2\pi}_0\int\limits^1_0 {4r-2r^{2} cost-r^{2} sint} dr dt\\\rm =\int\limits^{2\pi}_0( 2-2/3cost-1/3sint) dt\\\rm =4\pi[/tex]

Hence, The volume of the given solid below the plane 2x + y + z = 4 and above the disk x2 + y2 ≤ 1 is 4π.

Answer:

393.12 kids. This is technically impossible, as you can't have 0.12 of a kid, so I will round down to 393 kids.

Step-by-step explanation:

9% = 0.09

x = amount of kids who want to be lawyers

y = amount of kids who do not want to be lawyers

x = 0.09(432)

x = 38.88

y = 432 - 38.88
