Step-by-step explanation:

Given that :

{1,2,3,4,5,6,7,8,9,10,11,12,13,14}

Multiples of 2 : 2, 4, 6, 8, 10, 12, 14

Multiples of 3 : 3, 6, 9, 12

P(multiples o

(Multiples of 2 n multiples of 3) = {2,3,4,6,8,9,10,12,14} = 9

Answer:

5

Step-by-step explanation:

(I'm assuming that by m2 and n2 you mean m to the power of 2 and n to the power of 2)

Whenever you have a number to a power, it is the same as that number times itself that power number of times. For example, 3 to the power of 4 is equal to 3 times itself 4 times, which is 3 * 3 * 3 * 3. If we use this and substitute the values in for m and n, we get that 3^2 - 2^2, and since 3^2 is 3 * 3 and 2^2 is 2 * 2 and 3 times 3 is 9 and 2 times 2 is 4, we get that 9 - 4 is 5.

Note: This symbol means to the power of ----> ^

Answer:

-3.3>-10/3

Step-by-step explanation:

-10.3 is equal to -3.3333333333....

-3.3 just stops at the tenths so there is 0.033333333 more in -10/3. The higher the negative number the lower it is, for example -3>-4. Therefore, -3.3>-10/3.

Answer:

$25,500

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 7%/100 = 0.07 per year,

then, solving our equation

I = 15000 × 0.07 × 10 = 10500

I = $ 10,500.00

The simple interest accumulated

on a principal of $ 15,000.00

at a rate of 7% per year

for 10 years is $ 10,500.00.

The jeans cost $56.24 after the 25% discount.

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying it by 100.

The percentage change is also calculated using the same method.

In percentage change, we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

To find the price of the jeans after the 25% discount,

We need to multiply the original price by 0.75 (which is 100% - 25%).

So,

Discounted price = $74.98 x 0.75 = $56.24

Therefore,

The jeans cost $56.24 after the 25% discount.

Given:

The system of equations is

[tex]3y=\dfrac{3}{2}x+6[/tex]

[tex]\dfrac{1}{2}y-\dfrac{1}{4}x=3[/tex]

To find:

The solution of the given system of equations.

Solution:

The slope intercept form of a line is

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

We have,

[tex]3y=\dfrac{3}{2}x+6[/tex]               ...(i)

[tex]\dfrac{1}{2}y-\dfrac{1}{4}x=3[/tex]            ...(ii)

Rewritten the given equation in slope intercept forms.

In equation (i), divide both sides by 3.

[tex]y=\dfrac{1}{2}x+2[/tex]

Slope of this line is [tex]\dfrac{1}{2}[/tex] and y-intercept is 2.

In equation (ii), multiply both sides by 2 and isolate y variable.

[tex]y-\dfrac{1}{2}x=6[/tex]

[tex]y=\dfrac{1}{2}x+6[/tex]

Slope of this line is [tex]\dfrac{1}{2}[/tex] and y-intercept is 6.

Since slopes of both lines are same but the y-intercepts are different, therefore, the lines are parallel and the system of equations have no solution.

Therefore, the correct option is c.

p = 2

Step-by-step explanation:

[tex]\frac{p}{18}[/tex] = [tex]\frac{8}{72}[/tex]

to work with smaller numbers you can look to reduce

for example, 8/72 can be reduced to 1/9

[tex]\frac{p}{18}[/tex] = [tex]\frac{1}{9}[/tex]

now you can cross-multiply:

Answer:

193 gallons

Step-by-step explanation:

Given

[tex]A(t) = 30+8t-\frac{2}{3}(t+1)^{\frac{3}{2}}[/tex]

Required

Determine the maximum amount of water the tank can hold --- Missing from the question

Start by differentiating A w.r.t t

[tex]A'(t) = 0 + 8 + \frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}}][/tex]

Solving: [tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}}[/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -\frac{2}{3}\frac{d}{dt}[(t+1)^{\frac{3}{2}}[/tex]

Apply power rule:

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -\frac{2}{3}[\frac{3}{2}(t + 1)^{\frac{3}{2}-1} * \frac{d}{dt}[t+1][/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{3}{2}-1} * \frac{d}{dt}[t+1][/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{3}{2}-1} * [1+0][/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{3}{2}-1} * [1][/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{3}{2}-1}[/tex]

[tex]\frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}} = -(t + 1)^{\frac{1}{2}}[/tex]

So:

[tex]A'(t) = 0 + 8 + \frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}}][/tex]

A'(t) = 0 + 8 + \frac{d}{dt}[-\frac{2}{3}(t+1)^{\frac{3}{2}}]

[tex]A'(t) = 0 +8 -(t + 1)^{\frac{1}{2}}[/tex]

[tex]A'(t) = 8 -(t + 1)^{\frac{1}{2}}[/tex]

Equate to 0 to solve for t

[tex]A'(t) = 0[/tex]

[tex]8 -(t + 1)^{\frac{1}{2}} = 0[/tex]

Collect Like Term

[tex]-(t + 1)^{\frac{1}{2}} = -8[/tex]

Square both sides

[tex](-(t + 1)^{\frac{1}{2}})^2 = (-8)^2[/tex]

[tex]t +1 = 64[/tex]

Make t the subject:

[tex]t = 64 - 1[/tex]

[tex]t = 63[/tex]

So, the tank is at maximum when t = 63.

Substitute 63 for t in: [tex]A(t) = 30+8t-\frac{2}{3}(t+1)^{\frac{3}{2}}[/tex]

[tex]A(63) = 30+8*63-\frac{2}{3}(63+1)^{\frac{3}{2}}[/tex]

[tex]A(63) = 30+8*63-\frac{2}{3}(64)^{\frac{3}{2}}[/tex]

[tex]A(63) = 30+8*63-\frac{2}{3}*512}[/tex]

[tex]A(63) = 30+8*63-\frac{2*512}{3}}[/tex]

[tex]A(63) = 30+8*63-\frac{1024}{3}}[/tex]

[tex]A(63) = 30+8*63-341.33[/tex]

[tex]A(63) = 192.67[/tex]

Approximate:

[tex]A(63) = 193[/tex]

Answer:

$12.99n + $14.99s = $60

Step-by-step explanation:

The system of inequalities is n ≥ 1 and s ≥ 1  would represent this situation.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

Let n represent the number of nail boxes and s represent the number of screw boxes.

Nails will cost $12.99 if the price per box is $12.99.

In a similar vein, if a screw costs $14.99 a box, then s screws will also cost $14.99.

The carpenter can purchase n nails and s screws for a total of $60.

12.99n + 14.99 ≤ 60

Also, Since the carpenter needs to buy both nails and screws, it is necessary to buy at least 1 box of each of the two materials.

Therefore, the system of inequalities is n ≥ 1 and s ≥ 1  would represent this situation.

Answer:

Is 6x and 4x+2 equivalent

? No!

Step-by-step explanation:

6x doesn't equal 4x+2

In order for them to be the same you would have to add the same terms example:

4x+2x would equal 6x

Extra explaining:

The only way for those term to be added would be if they had the same variable since only 4x has a variable the 2 cant be added. In math you CANNOT move your variables off of a number and add them back on after.
