Answer:

392

Step-by-step explanation:

7(8) + 3(8)(14)

56 + 24(14)

56 + 336

392

Answer:

392.

Step-by-step explanation:

7m + 3mn Substitute the variables.

7(8) + 3(8)(14) Multiply from left to right.

Step-by-step explanation:

a number = x

Answer:

x=4

Step-by-step explanation:

18=3(3x-6)

Divide each side by 3

18/3=3/3(3x-6)

6 = 3x-6

Add 6 to each side

6+6 = 3x-6+6

12 = 3x

Divide by 3

12/3 = 3x/3

4 =x

Answer:

x = 2x + 15

x - 2x = 2x +15

-x = 15

-x /- = 15/-

x = -15

Step-by-step explanation:

hope that will help you.

Answer:

x = −15

Step-by-step explanation:

x−2x = 2x+15−2x

−x = 15

−x/−1 = 15/−1

x = −15

Answer:

[tex]110\geq x \leq 220[/tex]

Step-by-step explanation:

Given

Minimum: 110

Maximum = 220

Required

Write as interval notation

Let the real numbers be represented with x

We start by setting x greater than or equal to the minimum:

[tex]x \geq 110[/tex]

Then, we set x less than or equal to the maximum:

[tex]x \leq 220[/tex]

Write out both inequalities

[tex]x \geq 110[/tex] and [tex]x \leq 220[/tex]

This can be rewritten as:

[tex]110 \geq x[/tex] and [tex]x \leq 220[/tex]

Both inequalities can be merged to give:

[tex]110\geq x \leq 220[/tex]

Answer:

(110,220)

I not sure about this answer but if I correct than your welcome and if I wrong then sorry.

Answer:

B. 0.03110

Step-by-step explanation:

Given

Probability of Hit = 60%

Required

Determine the probability that he misses at 6th throw

Represent Probability of Hit with P

[tex]P = 60\%[/tex]

Convert to decimal

[tex]P = 0,6[/tex]

Next; Determine the Probability of Miss (q)

Opposite probabilities add up to 1;

So,

[tex]p + q = 1[/tex]

[tex]q = 1 - p[/tex]

Substitute 0.6 for p

[tex]q = 1 - 0.6[/tex]

[tex]q = 0.4[/tex]

Next,is to determine the required probability;

Since, he's expected to miss the 6th throw, the probability is:

[tex]Probability = p^5 * q[/tex]

[tex]Probability = 0.6^5 * 0.4[/tex]

[tex]Probability = 0.031104[/tex]

Hence;

Option B answers the question

Answer:

b) 0.03110

Step-by-step explanation:

Got it right on the test.

Answer:

[tex]x^3[/tex]-15[tex]x^{2}[/tex]+25x-125

Step-by-step explanation:

This is a quadratic equation, so we need to open the equation first. There are three (x-5), and then we multiply them together, and then combine like terms to get the answer.

(x-5)(x-5)(x-5)=

[x(x-5)-5(x-5)](x-5)=

([tex]x^{2}[/tex]-5x-5x+25)(x-5)=

([tex]x^{2}[/tex]-10x+25)(x-5)=

x([tex]x^{2}[/tex]-10x+25)-5([tex]x^{2}[/tex]-10x+25)

[tex]x^3[/tex]-[tex]10x^2[/tex]+25x-[tex]5x^2[/tex]-125=

[tex]x^3[/tex]-15[tex]x^{2}[/tex]+25x-125

Because there are 13 problem and if she completed 12 of them yesterday .Only 1 will be left for today.

======================================================

Explanation:

Check out the diagram below. Locate -2 on the horizontal x axis. Draw a vertical line through this value. Mark where the vertical line crosses the curve. Call this point P. Then draw a horizontal line through point P to have it cross the y axis. This horizontal line crosses at y = 1

In short, x = -2 leads to y = 1

So that is why f(-2) = 1

This is another way of saying f(x) = 1 when x = -2.

Note: y = f(x) since both are outputs of a function

Answer:

MO = 17

Step-by-step explanation:

First, you need to define what if the unknown x.

segment MN and NO are equal to MO.

thus, your equation for the combination is x +8

Now set the values equal to each other

x + 8 = 3x - 10 (subtract x from both sides)

8 = 2x - 10 ( get your x value alone, add 10 to both sides)

18 = 2x (simplfy)

x = 9

Now plug x value into MO

3 (9) - 10 = 17

Check with opposing equation:

9 + 8 = 17 √

Answer:

TRUE

Step-by-step explanation:

if the adjacent angles are equal, then they are right angles.

Step-by-step explanation:

The translation path of Point A (3, -8) to A'(-4,-5) exists 3 units down and 7 units to the left.

A translation in mathematics does not turn, but rather moves a shape left, right, up, or down. Congruent translations are those in which the translated shapes (or the image) seem to be the same size as the source ones. Just one or more directions have they shifted.

Each point in a figure is moved by the same amount and in the same direction during a translation, a type of transformation.

With a sort of transformation called translation, every point in a figure is moved the same distance in the same direction.

The translation path of Point A (3, -8) to A'(-4,-5) exists 3 units down and 7 units to the left.

Answer:

[tex] d = \sqrt{205} [/tex]

Step-by-step explanation:

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] d = \sqrt{(-8 - (-2))^2 + (7 - (-6))^2} [/tex]

[tex] d = \sqrt{(-6)^2 + 13^2} [/tex]
