Answer:

- 6 and - 4

Step-by-step explanation:

Given

- [tex]\frac{1}{2}[/tex] x + 4 ≥ 6 ( subtract 4 from both sides )

- [tex]\frac{1}{2}[/tex] x ≥ 2

Multiply both sides by - 2 to clear the fraction, reversing the symbol as a result of multiplying by a negative quantity.

x ≤ - 4

The only values from the set which satisfy the inequality are

Answer:

11 cm

Step-by-step explanation:

A = [tex]s^{2}[/tex]

Known that A = 121 [tex]cm^{2}[/tex],

121 [tex]cm^{2}[/tex] = [tex]s^{2}[/tex]

s = [tex]\sqrt{121}[/tex] cm = 11 cm

Done :)

The side length of a square launch pad is 11 centimeter.

Here,

Darius is building a square launch pad for a rocket project.

The area of the pad is 121 square centimeters.

We have to find, it's side length.

What is Area of square?

The area of a square = side x side

Since each side of a square is the same, it can simply be the length of one side squared.

Now,

The area of the pad is 121 square centimeters.

We use the area formula,

⇒[tex]A = s^{2}[/tex]

⇒ [tex]s^{2} = 121[/tex]

⇒[tex]s = \sqrt{121}[/tex]

⇒ [tex]s = 11[/tex]

Hence, The side length of a square launch pad is 11 centimeter.

Given that the radius of the puddle expands, originally, at a rate of 1/4 unit/second instead of 1/2 unit/second.

The current rate of expension of the radius,

\frac {r(t)}{t}=frac 1 4 unit/second ...(i)

The resultant composite function is area, A(r(t)).

The area of a circular region having radius r is,

[tex]A(r)=\pi r^2[/tex]

If the radius is the function of time, then the composite function is

[tex]A(r(t))=\pi \(r(t))^2[/tex]

To determine the rate of change of area with respect to time, differentiate the composite function A(r(t)) once with respect to time, we have

[tex]\frac {d\{A(r(t))\}}{dt}=\pi \left(2\frac {d\{r(t)\}}{dt}\right)[/tex]

So, the composite function is changing twice of the rate of change of the radius.

By using equation (i), if r(i) is changing with R= 1/4 unit / second.

Then, A(r(t)) will change 2 x 1/4 = 1/2 square unit/second.

Answer:

A'(-4, 8), B'(3, 6), C'(-6, -1)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation.

If a point X(x, y) is reflected about the y = x line, the new location is X'(y, x)

Triangle ABC has vertices at A(8.-4), B(6,3), and C(-1.-6), if it is reflected about the y = x line, the new location is A'(-4, 8), B'(3, 6), C'(-6, -1)

Answer:

r = -9

Step-by-step explanation:

Subtract 8 from both sides to get 2r = -18. Divide by 2 on both sides to get r = -9.

Answer:

r=-9

Step-by-step explanation:

Step 1:- Simplify both sides of the equation.

2r+8 = -10

Step 2:- For isolating the variable, subtract 8 from both sides.

2r+8-8 = -10-8

2r = -18

Step 3:- For isolating the variable, divide by 2 from both sides.

2r/2 =-18/2

r= -9

Answer:

-10, 10

Step-by-step explanation:

To do that, we can set up an equation:

[tex]8x^2-800=0[/tex]

We can divide both sides by 8 to make it easier to solve:

[tex]x^2-100=0[/tex]

Now, isolate the x and take the square root of both sides:

[tex]x^2=100\\x=\pm10[/tex]

Therefore, the 2 zeroes of f(x) are -10 and 10.

Answer:

the correct answer is 84.5$

Step-by-step explanation:

The way how i got this because 3*9 for the t shirts

2*20 for the jeans

and 5*3.50 for the socks

Answer:

$84.50

Step-by-step explanation:

So we know she buys 3 nine dollar shirts

$9.00 times 3 shirts is $27.00

She also buys two pairs of jeans

$20.00 times 2 is $40.00

Finally she buys 5 pairs of socks

$3.50 times 5 is 17.50

so lets add it all up

27.00

40.00

17.50

=84.50

Answer: x > -12

Step-by-step explanation:

Answer:

x = -51/2

Step-by-step explanation:

f(x) = 2x + 61 - 4

Since we are looking for the values where f(x) = 6, replace f(x) with 6 in the equation:

6 = 2x + 61 -4

Next combine like terms:

6 = 2x + 57

Then move subtract 57 from both sides to isolate the variable:

-51 = 2x

Finally, divide both sides by two to get x by itself:

x =-51/2

Answer:

2. 13 cm

3. 15 boxes

4. $76.88

5. 14

Step-by-step explanation:

1. 14 + 4 = 18. 18 - 6 = 12. 12 + 9 = 21. 21 - 15 = 6

2. 208 ÷ 16 = 13

3. 21 - 15 = 6. 6 + 30 = 36. 36 - 27 = 9. 9 + 22 = 31. 31 - 16 = 15

4. 138.75 + 115.07  = 253.82. 253.82 - 176.94 = 76.88

5. ? + 7 + 4 - 5 + 21 - 2 + 4 = 43. First you need to combine all of it:

43 - 29 = 14

Step-by-step explanation:

Given that there are tickets in the draw which are numbered from 1 to 25.

Probability of an event E is given by the formula:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Probability of each number can be found out as:

Number of favorable cases for each number is 1 and total number of cases here is equal to the total number of tickets i.e. 25.

[tex]P(Each\ Number) = \dfrac{1}{25}[/tex]

Now, the numbers less than 5 mean 1, 2, 3 and 4.

Therefore, 4 number of favorable cases.

[tex]P(1, 2, 3\ or\ 4) = \dfrac{4}{25}[/tex]

Now, it is given that 40 tickets are drawn.

Number of times, the numbers less than 5 are expected:

Answer:

20p = x

Step-by-step explanation:

Since Lily sold 5 purses in week one and 15 purses in week two that adds up to be a total of 20 purses sold in two weeks. Since p represents the profit for each purse she can use the expression below which simply multiplies the profit per purse (p) by the total amount of purses sold in the two weeks which would give her the total amount of profit (x) that she made from all of her sales.

20p = x
