Solve the following proportions p/18= 8/72 pls help
Answer:
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:
9p = 18
p = 18/9 which is 2
Nick bought a pair of jeans that originally cost $74.98. The jeans were markdown 25%. How much did the jeans cost after the discount?
The jeans cost $56.24 after the 25% discount.
What is a percentage?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.

what is the greatest common factor for the two expressions?
15³ and 12²
Answer:
Your answer would be 9.
Step-by-step explanation:
12*12=144
15*15*15=3375
The factors of 144 are: 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 36, 48, 72, 144
The factors of 3375 are: 1, 3, 5, 9, 15, 25, 27, 45, 75, 125, 135, 225, 375, 675, 1125, 3375
So the greatest common factor would be 9 since is the largest number that is the same for both of the numbers.

What is the solution of this system of linear equations? 3y=3/2x+6 1/2y-1/4x=3 a.(3, 6) b.(2, 1) c.No solution d.Infinite number of solutions
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.

Answer:
0.643
Step-by-step explanation:
Given that :
{1,2,3,4,5,6,7,8,9,10,11,12,13,14}

If m= 3 and n= 2, then m2-n2 is equal to
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 ----> ^

The total number of gallons of water in a tank at time t is modeled by the expression A(t)=30+8t-2/3(t+1)^3/2
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:
-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.

A carpenter has $60 with which to buy supplies. The carpenter needs to buy both nails
and screws. Nails cost $12.99 per box, and screws cost $14.99 per box. If n represents the
number of boxes of nails and s represents the number of boxes of screws, which of the
followina sustems of inequalities models this situation?
Answer:
$12.99n + $14.99s = $60
Step-by-step explanation:
The system of inequalities is n ≥ 1 and s ≥ 1 would represent this situation.
What is inequality?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.
