Answer:

[tex]x\leq 36[/tex]

The solution for [tex]x[/tex] is all real numbers less that or equal to 36.

Step-by-step explanation:

Given expression:

[tex]\frac{1}{2}x\leq18[/tex]

To find the solution for [tex]x[/tex]

Solution:

In order to solve for [tex]x[/tex] , we will make sure to isolate the unknown variable [tex]x[/tex] on left side alone by doing math operations on both sides of the inequality.

We have:

[tex]\frac{1}{2}x\leq18[/tex]

Multiplying both sides by 2.

[tex]2.\frac{1}{2}x\leq18\times 2[/tex]

The 2 on left side will cancel each other leaving [tex]x[/tex] alone.

Thus, we have:

[tex]x\leq 36[/tex]

Thus, solution for [tex]x[/tex] is all real numbers less that or equal to 36.

Answer:

The value of A is [tex](-\infty, 0) \cup(0, \infty)[/tex]

Step-by-step explanation:

Given:

[tex]V = A (t- 0.05t^2)[/tex]

When velocity V= 0

we have

[tex]A (t- 0.05t^2) = 0[/tex]

[tex](t- 0.05t^2) = 0[/tex]

[tex]t = 0.05t^2[/tex]

t =0 , t = [tex]\frac{1}{0.05}[/tex]

t = 0 , t = 20

So when we draw a graph,The resulting graph will be  a quadratic graph.

[tex]\frac{dv}{dt} = A[1 - 0.1t][/tex]

[tex]\frac{dv}{dt} = 0[/tex]

t=10 sec

At t=10, the velocity will be

[tex]v(10) = [10 -0.05(10)^2][/tex]

[tex]v(10) = [10 -5][/tex]

[tex]v(10) = 5A[/tex]

But according to the question A is not dependent on t

So A can be any  value other than zero

Answer:

Money Jevon would be having = $15

Money Angie would be having = $30

Money Kenny would be having = $35

Step-by-step explanation:

Given:

Angie has twice as much money as Jevon

Kenny has $5 more than Angie.

The sum of their treasure = $80

To find how much money does each of them have.

Solution:

Let Jevon has money in dollars = [tex]x[/tex]

Angie having twice as much money as Jevon would have in dollars = [tex]2x[/tex]

Kenny having $5 more than Angie would have in dollars = [tex]2x+5[/tex]

The sum of their money will be given as:

⇒ [tex]x+2x+2x+5[/tex]

Combining like terms.

⇒ [tex]5x+5[/tex]

The sum of their treasure = $80

So, the equation to find [tex]x[/tex] would be given as:

[tex]5x+5=80[/tex]

Solving for [tex]x[/tex]

Subtracting both sides by 5.

[tex]5x+5-5=80-5[/tex]

[tex]5x=75[/tex]

Dividing both sides by 5.

[tex]\frac{5x}{5}=\frac{75}{5}[/tex]

∴ [tex]x=15[/tex]

Thus,

Jevon has = $15

Angie has = [tex]2\times \$15[/tex] = $30

Kenny has =  [tex]\$30+\$5[/tex] = $35

Answer:

The owner can use between 5 and 20 HCF to stay in the conservation range

Step-by-step explanation:

Let's calculate the number of HCF, this way:

Lower value = (31.32 - 24.72)/1.32 = 6.60/1.32 = 5

Upper value = (52.12 - 24.72)/1.32 = 27.4/1.32 = 20.76 = 20 as truncated value

The owner can use between 5 and 20 HCF to stay in the conservation range

The owner can use between 5 and 20 hcf to stay within the conservation range.

To find the range for the number of hcf the owner can use, we need to subtract the base cost from the maximum and minimum bill amounts. The base cost is $24.72, so subtracting this from the maximum bill amount of $52.12 gives us $27.40. Similarly, subtracting the base cost from the minimum bill amount of $31.32 gives us $6.60. In order to determine the maximum and minimum number of hcf, we divide these amounts by the additional cost per hcf, which is $1.32.

The maximum number of hcf would be $27.40 divided by $1.32, which is approximately 20 hcf. The minimum number of hcf would be $6.60 divided by $1.32, which is approximately 5 hcf.

Therefore, the owner can use between 5 and 20 hcf to stay within the conservation range.

Answer:  identity is subtraction property of equality equation is x + 8 = 6

Substitution Property of Equality; x + 8 = 6

Take the equation x + 8 = 6. subtract 8 from both sides using the subtraction property of equality x + 8 - 8 = 6 - 8 simplify x + 0 = -2 x = -2

The Addition Property of Equality and the equation x + 6 = 8 are the property and equation that satisfy the statement 'The solution of an equation is x = –2'. This is because when you subtract 6 from both sides of the equation, x equals -2.

To find the property and equation that fits the statement 'The solution of an equation is x = –2', we need to understand the basic properties of equality and apply those in this context.

Following the statement, it seems that the Addition Property of Equality fits the best here. The Addition Property of Equality states that when we add the same number to both sides of an equation, the equation remains balanced and the solution is the same. Now, if we think of an equation 'x + 6 = 8', and solve it using the Addition Property by subtracting 6 from both sides, we get the solution x = -2.

That means the property that satisfies the statement is Addition Property of Equality and the equation that satisfies the statement is x + 6 = 8.

Answer:

radius = 6 cm

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = [tex]\frac{4}{3}[/tex] πr³ ← r is the radius

Given V = 288π, then

[tex]\frac{4}{3}[/tex] πr³ = 288π

Multiply both sides by 3 to clear the fraction

4πr³ = 864π ( divide both sides by 4π )

r³ = 216 ( take the cube root of both sides )

r = [tex]\sqrt[3]{216}[/tex] = 6

Thus the radius of the sphere is 6 cm

To find the sphere's radius from its given volume of 288pi cm^3, we use the volume formula V = (4/3) π r³ and solve for r, resulting in a radius of 6 cm.

The student is asking for the radius of a sphere given its volume, which is 288pi cm³. To find the radius, we need to use the formula for the volume of a sphere:

V = (4/3) π r³

Where V is the volume and r is the radius. We can solve for r by rearranging the formula:

r = √[3V / (4π)]

In this case, substituting the given volume into the equation:

r = √[3(288π) / (4π)]

r = √[864π / (4π)]

r = √[216]

The radius of the sphere is 6 cm.

The value of log base 12 of y² is evaluated by using the power rule of logarithms. Given that log base 12y equals 16, the value of log base 12 of y² is calculated to be 32.

The student asked to evaluate log base 12 of y², given that log base 12y = 16. From the given information, we have:

log12(y) = 16

Using the power rule of logarithms, which states that logb(xy) = y. logb(x), we can express the asked expression log12(y²) as:

log12(y²) = 2 . log12(y)

Since we are given that log12(y) = 16, we can substitute this value into our previous equation:

log12(y²) = 2 . 16 = 32.

Therefore, the value of log12(y²) is 32.

No. All the lengths will not be the same.

Step-by-step explanation:

Martha wants to make four necklaces that are the same length. She asked her friends to cut the string for the necklaces 15 paper clips long.

We are asked whether all the four lengths will be of the same length or not.

If Martha uses the paper clips to measure the lengths of the cut pieces of strings, then all the lengths will not be the same because 15 is not divisible by 4.

The lengths maybe 4, 4, 4, and 3 paper clips of lengths. (Answer)

Length of each string is 3.75 paper clips

Number of neckless = 4

Length of string = 15 paper clips

Length of each string

Length of each string = Length of string / Number of neckless

Length of each string = 15 / 4

Length of each string = 3.75 paper clips

Answer:

The value of x is 8

Step-by-step explanation:

In the figure below,

The alternate exterior angles are  1 and 2

Alternate Exterior Angles are a pair of angles that lie on the  outer side of each of those two lines but on opposite sides of the transversal and they are equal

Also  angle 2 and 3 are adjacent and supplementary angle and their sum is equal to 180 degrees

Given that

[tex]\angle 1 = (4x + 28)^{\circ}[/tex]

[tex]\angle 3 = (14x + 8)^{\circ}[/tex]

Now we know that

[tex]\angle 2 + \angle 3 = 180 ^{\circ}[/tex]

[tex]\angle 2 +(14x+8) = 180[/tex]

[tex]\angle 2 = 180 - 14x -8[/tex]

[tex]\angle 2 = 172 - 14x[/tex]

We also know that

[tex]\angle 1 = \angle 2[/tex]

[tex]4x + 28 = 172 -14x[/tex]

[tex]4x + 14x = 172 - 28[/tex]

[tex]18x = 144[/tex]

[tex]x =\frac{144}{18}[/tex]

x = 8

Now

[tex]\angle 1 = (4x+28)^{\circ} = (4(8) +28)^{\circ} = (32 +28)^{\circ} =(60)^{\circ}[/tex]

[tex]\angle 3= (14x+8)^{\circ} = (14(8) +8)^{\circ} = (112 +8)^{\circ} =(120)^{\circ}[/tex]

Answer:

y = 5x + 17

Last choice

Step-by-step explanation:

The equation for a line can be written in the form y = mx + b. (This is called slope-intercept form).

"x" and "y" mean points on the line.

"m" means the slope of the line, which is how steep the line is.

"b" means the y-intercept, which is when the line hits the y-axis.

To write an equation in slope-intercept form, we need the slope and y-intercept.

We know the slope needs to be 5.

m = 5

We know one point on the line, (-4, -3). Points are written (x, y), so:

x = -4

y = -3

Substitute the numbers we know for "m", "x" and "y" into the equation for a line. Then, we can isolate 'b' to know what it equals.

y = mx + b

-3 = (5)(-4) + b       Multiply to simplify

-3 = -20 + b        Start isolating 'b'

-3 + 20 = -20 + 20 + b     Add 20 to both sides to cancel out on the right.

-3 + 20 = b     Solve the left side.

17 = b      Answer

b = 17    Put variable on left side for standard formatting

Now that we know m = 5 and b = 17, rewrite the equation in the form y = mx + b.

y = 5x + 17

Final answer:

The perimeter of the square defined by the city block is 616 meters.

Explanation:

In order to find the perimeter of the square block, we need to know the length of each side. The question states that each side of the block is 154 m, so we can use this information to calculate the perimeter. The perimeter of a square is equal to four times the length of one side, so in this case it would be 4 * 154 m = 616 m. Therefore, the perimeter of the square defined by this city block is 616 meters.
