Anybody can help me with this math question please?

Answer:

x ≥5  or  5 ≤x

Step-by-step explanation:

2x ≤ 5x - 15

Subtract 5x from each side

2x-5x ≤ -15

-3x ≤-15

Divide each side by -3, remembering to flip the inequality

-3x/-3 ≥ -15/-3

x ≥5

Check x=10

2*10 ≤5*10 -15

20 ≤50 -15

20 ≤35

True

Probability of heads is:

The probability of both is:

Answer:

Step-by-step explanation:

t1 = 10

t(n) = 3t_(n - 1) - 1

t(2) = 3*t(2 -1) - 1

t(2) = 3*t1 - 1

t(2) = 3*10 - 1

t_2= 30 - 1

t_2 = 29

t3 = 3*t2 - 1

t3 = 3*29 - 1

t3 = 87 - 1

t3 = 86

t4 = 3*t3 - 1

t4 = 3*86 - 1

t4 = 258 -1

t4 = 257

Answer:-28

Step-by-step explanation:

Let A is the second number

the first number is 10.

The total is -18

=> 10 + A =-18 <=> A=-18-10=-28

Answer:

549.5 ft

Step-by-step explanation:

This question is valid only if the rug is round and the rug diameter is d = 7 ft.

It calls for the circumference of the rug, times 25:  25(pi*d)

Distance walked:  25(3.14)(7 ft) = 549.5 ft

Answer:

yes

Step-by-step explanation:

To determine if the triangle is right

If the square of the longest side is equal to the sum of the squares on the other 2 sides then it is right.

longest side = 20 and 20² = 400

12² + 16² = 144 + 256 = 400

Thus the triangle is right

We know that,

Volume of sphere = 4/3πr³

41572 = 4/3 × 22/7 × r³

41573 × 21/88 = r³

³√9,920.82 = r

21.48 cm = r

:)

The radius of a sphere with a volume of 41572 cm³ is,

⇒ 21.4 cm

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now, To find the radius of a sphere with a volume of 41572 cm³, we can use the formula for the volume of a sphere as;

⇒ V = (4/3)πr³

where V is the volume and r is the radius.

Hence, We can rearrange this formula to solve for r:

⇒ r = ∛ (3V/4π)

Substituting the given volume, we have:

r = ∛ (3(41572)/4π)

r ≈ 21.4 cm

Therefore, the radius of the sphere to the nearest tenth of a centimeter is 21.4 cm.

Answer:

C

Step-by-step explanation:

As you can see, the dot on the line is the starting point and it is open.

An open dot means less than or more than. An closed dot means less than or equal to / more than or equal to.

The line is going right starting from -5, so it is more than 5.

Step-by-step explanation:

After graphing the function f(x) = [tex]4(\frac{1}{2})^{x}[/tex]  we can see that the correct graph is the middle one in the picture. This is because with an x-input of 1 the value of 1/2 will stay the same and when multiplied by 4 it would give us a y-coordinate of 2 as seen in the middle graph. The y-coordinate keeps decreasing exponentially by half for every increase in the x-coordinate. A zoomed-in version of the graph can be seen in the attached picture below for a better understanding.

Answer:

B' (- 7, 6 )

Step-by-step explanation:

Given the translation rule

(x, y ) → (x + 2, y + 5 )

This means add 2 to the original x- coordinate and add 5 to the original y- coordinate, then

B (- 9, 1 ) → B' (- 9 + 2, 1 + 5 ) → B' (- 7, 6 )

Step-by-step explanation:

perimeter of rectangle=2(length + breadth)

=2(2p+q+p)

=2(3p+q)

=2*3p+2*q

=6p+2q cm

Step-by-step explanation:

Hey there!

From the figure;

Length (l) = 2p + q cm

Base (b) = pcm

Now;

Perimeter (p) = 2(l+b)

P = [2(2p+q) + p]

or, P = 2(3p+q)

or, P = 6p + 2qcm.

Therefore, perimeter (p) = 6p+2q cm.

Answer:

n = (1/2)(-1 ± i√2)

Step-by-step explanation:

Among the several ways in which quadratic equations can be solved is the quadratic formula.  Putting to use the coefficients {12, 12, 9}, we obtain the discriminant, b^2 - 4ac:  12^2 - 4(12)(9) = 144 - 432 = -288.  The negative sign of this discriminant tells us that the quadratic has two unequal, complex roots.  These roots are:

      -b ± √(discriminant)

n = ---------------------------------

                 2a

Here we have:

      -12 ± √(-288)           -12 ± i√2√144          -12 ± i12√2

n = ----------------------  =  ------------------------ =  --------------------

            2(12)                             24                           24

or:

n = (1/2)(-1 ± i√2)
