Area model for division 427÷7

Answer:

3.1%

Step-by-step explanation:

53.80/1625 x 100 is 3.1

Hope this helps plz hit  the crown ;D

So what you can do is divide 53.10 by 1735 to get percentage

0.0306051873 is your decimal, so move it right 2 places to get

3.06% of his money.

You asked for the nearest 10th of a percent, so you round that to

3.1%

Answer:

they did not pay the same rate.

2 pairs for $50

50÷2=25

Miguel spent $25 on each pair of jeans

4 pairs for $90

90÷4=22.5

Han spent $22.50 on each pair of jeans

Therefore these two did not pay the same rate.

Given:

The exponential function passes through two points (0,4) and (3,32).

To find:

The formula for the exponential function.

Solution:

The general form of an exponential function is

[tex]y=ab^x[/tex]          ...(i)

where, a is initial value and b is growth factor.

The exponential function passes through two points (0,4) and (3,32). It means the function must be satisfy by these points.

Putting x=0 and y=4 in (i), we get

[tex]4=ab^0[/tex]

[tex]4=a(1)[/tex]

[tex]4=a[/tex]

Putting a=4, x=3 and y=32 in (ii), we get

[tex]32=4b^3[/tex]

Divide both sides by 4.

[tex]8=b^3[/tex]

Taking cube root on both sides.

[tex]2=b[/tex]

Putting a=4 and b=2 in (i), we get

[tex]y=4(2)^x[/tex]

Therefore, the required formula for the exponential function is [tex]y=4(2)^x[/tex].

Answer:

[tex]\frac{56}{15}[/tex]

Step-by-step explanation:

Given that [tex]\vec F(x, y, z) = x^2y \hat i + xy^2 \hat j + 3xyz \hat k[/tex]

F(x, y, z) = x^2y \hat i + xy^2 \hat j + 3xyz \hat k

The flux of \vec F across the surface S is given by

[tex]\int \int _s \vec F \cdot dS[/tex]

Where the survare S is the surface of the tetrahedron bounded by the planes x = 0, y = 0, z = 0, and  x + 4y + z = 4.

Now, by using the Gauss Divergence theorem:

[tex]\int \int _s \vec{F} \cdot dS=\int \int \int _v \bigtriangledown \cdot \vec F dV[/tex]...(i)

where V is the volume enclosed by the surface S and [tex]dV=dxdydz[/tex]

\bigtriangledown \cdot \vec F = \hat i \frac {\partial \vec F}{\partial x}+\hat j \frac {\partial \vec F}{\partial y}+\hat k \frac {\partial \vec F}{\partial z}

=2xy+2xy+3xy=7xy

Putting this value in equation (i), we have

\int \int \int _v \bigtriangledown \cdot \vec F dV = \int \int \int _v (7xy)dxdydz

= [tex]7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y} \left( \int_{z=0}^{z=4-x-4y}xy\;dz\right)dxdy[/tex]

[tex]=7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y} xy(4-x-4y-0)dxdy \\\\=7\int_{y=0}^{y=1} \int_{x=0}^{x=4-4y}(4xy-x^2y-4xy^2)dxdy \\\\=7\int_{y=0}^{y=1} (2x^2y-\frac 1 3 x^3y-2 x^2y^2)|_{x=0}^{x=4-4y}dy \\\\[/tex]

[tex]=7\int_{y=0}^{y=1} (2(4-4y)^2y-\frac 1 3 (4-4y)^3y-2 (4-4y)^2y^2)dy[/tex]

[tex]=7\int_{y=0}^{y=1} (32(1-y)^2y-\frac {64}{3} (1-y)^3y-32(1-y)^2y^2)dy[/tex]

[tex]=7\int_{y=0}^{y=1} (32(1-2y+y^2)y-\frac {64}{3} (1-y^3-3y+3y^2)y-32(1-2y+y^2)y^2)dy[/tex]

[tex]=7\int_{y=0}^{y=1} \{32(y-2y^2+y^3)-\frac {64}{3} (y-y^4-3y^2+3y^3)-32(y^2-2y^3+y^4)\}dy[/tex]

[tex]=7 \{32(\frac 1 2 y^2- \frac 2 3 y^3+\frac 1 4 y^3)-\frac {64}{3} (\frac 1 2 y^2-\frac 1 5 y^5-y^3+\frac 3 4 y^4)-32(\frac 1 3 y^3-\frac 1 2 y^4+\frac 1 5 y^5)\} |_{y=0}^{y=1}[/tex]

[tex]=7 \{32(\frac 1 2 - \frac 2 3 +\frac 1 4 )-\frac {64}{3} (\frac 1 2 -\frac 1 5 -1+\frac 3 4 )-32(\frac 1 3 -\frac 1 2 +\frac 1 5 )\}[/tex]

[tex]=7\times \frac {8}{15} \\\\=\frac{56}{15}[/tex]

Hence, the flux of F across S is [tex]\frac{56}{15}[/tex].

Step-by-step explanation:

A production manager at a wall clock company wants to test their new wall clocks. The designer claims they have a mean life of 16 years with a standard deviation of 5 years. If the claim is true, in a sample of 32 wall clocks, what is the probability that the mean clock life would be greater than 15.6 years

Answer: 12n + 60

Step-by-step explanation:

So first you have to distribute the 5 in the parentheses.

(5)(n + 12) = 5n + 60

5n + 60 + 7n

Then add like terms.

12n + 60

Answer:

Pedro had a gain of 1.2%

Step-by-step explanation:

Percentages

Pedro bought two cars. One for $600,000 and the other for $400,000.

He sold the first car at a 10% profit. Thus the gain was:

$600,000 * 10 / 100 = $60,000

He sold the other car at a 12% loss. Thus the loss was:

$400,000 * 12 / 100 = $48,000

The total gain or loss was $60,000 - $48,000 = $12,000

Since it's positive, the total balance is at gain.

The total investment was $600,000 + $400,000 = $1,000,000

The total gain is a percentage of the total investment of:

$12,000 / $1,000,000 * 100 = 1.2%

Pedro had a gain of 1.2%

Answer:

4 + y = 96 = 100

y = 104 - 4 = 100

4 y = 25 = 100 4 + 100 = y = 104

100 = y = 105 - 5

Step-by-step explanation:

Plz mark me as brainliest have a good day

The equations could you solve using the addition property of equality is

y- 4 = 100.

We have to apply the property of addition equality

Now,

4 + y = 100

y= 96

and, y -4 = 100

y = 104

and, 4 y = 100

y= 25

and, 100 = y - 5

y= 105

Thus, the required equality is y- 4 = 100.

Step-by-step explanation:

Heya! Considering that the question has already given you the values of x and y, all you are left to do is plug them back into the equation. The value of 6 multiplied by x- 5- gets you to 30. Since y is equal to 1, 3 multiplied by 1 gets you 3. 30-3 gets you to 27, so that is your answer. I hope this helped! (Please mark as branliest if I did happen to get this right. <3)

Step-by-step explanation:

But if you take the number of Peaches and subtrqact the number of oranges will have your answer.

Answer:

Step-by-step explanation:

since the first equation is already simplifies to y = 2x plug in 2x for the y in the second equation and solve

x = -(2x) + 6

x = -2x + 6

3x = 6

x = 2

plug in our x to the original equation

y = 2(2)

y = 4

so our answer is (2,4)

hope this helps <3

Answer:

x = 2

Step-by-step explanation:

If y is 2x, and x is -y + 6, what's x?

So let's use substitution method. Just replace the -y in x = -y + 6 with 2x:

x = -y + 6

x = -2x + 6

add 2x to both sides

3x = 6

divide by 3

x = 2
