Pick a number less than or equal to 30 from a bag with 40 pieces of paper
numbered 1 through 40.

Answer:

15.

Step-by-step explanation:

5 * - 5 + 40 = 15

Answer:

15

Step-by-step explanation:

f(x) = 5x + 40

Let x = -5

f(-5) = 5(-5) + 40

Multiply

      = -25+40

Add

    = 15

Answer:

It would be A

Step-by-step explanation:

Step-by-step explanation:

A. D(t) = -25t + 160

this is the correct answer because if you substitute 3 you get 85

Answer:

23.6 and 106.4

Step-by-step explanation:

Answer:

h = -4

Step-by-step explanation:

3(h+6) = 2(-5-2h) Solve for h.

Apply distributive property first on both sides.

3(h+6) = 2(-5-2h)

3h+18 = -10-4h

Next, put the terms with h on one side and the numbers on the other.

3h+18 = -10-4h

7h = -28

Divide both sides by 7 and you have your answer.

7h = -28

h=-4

Answer:

-4

Step-by-step explanation:

First, expand the brackets by multiplying the left bracket all by 3 and the right all by 2. This gives 3h+18=-10-4h.

You want h all on one side, so add 4h to both sides, leaving 7h+18=-10.

Subtract 18 on both sides to leave only h and the coefficient on the left. This gives 7h=-28.

Dividing both sides by 7 isolates the x and gives h=-4.

Answer:

-11xy

Step-by-step explanation:

-14xy -(-3xy)

multiply the bract first - sign * minus sign is plus sign

-14xy+3xy

since they are like terms u can subtract them.u should subtract them because minus and plus means subtract and we should put minus sign in front of the answer because 14 is the highest number and it's sign is negative .

-11xy

Answer:

[-1, 6)

General Formulas and Concepts:

Algebra I

Algebra II

Step-by-step explanation:

According to the graph, our y-values span from -1 to 6. Since -1 is a closed dot, it is inclusive. Since 6 is an open dot, it is exclusive:

Range would then be [-1, 6).

Answer:

66.7%

Step-by-step explanation:

Please find attached the complete question

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability that a randomly selected point within the circle falls in the white area = degree occupied by white area / sum of angles in a circle

sum of angles in a circle = 360

degree occupied by white area = sum of angles in a circle - sum of degrees of shaded area

360 - (60 + 60) = 240

240 / 360

convert to its simplest form by dividing by 120 = 2/3

2/3 x 100 = 66.7%

Answer:

g(x) = 0.5x²

Step-by-step explanation:

Since the graph of g(x) still passes through the origin and is u shaped, it is also a quadratic graph but with a different coefficient of x².

Let g(x) = ax²

When x=2, g(x) = 1

Hence, 2a = 1

a = 0.5

Therefore, g(x) = 0.5x²

1) 2(x + 7)

2x + 14

2) 8 (x - 3)

3) -4 (y - 6)

Answer:

450

Step-by-step explanation:

Answer:

x = (k-14)/5

Step-by-step explanation:

5x + 14 = k

Subtract 14 from each side

5x + 14-14 = k-14

5x = k-14

Divide by 5

5x/5 = (k-14)/5

x = (k-14)/5

Answer:

k - 14/5

Step-by-step explanation:

5x + 14 = k

On subtracting 14 on both sides,

5x = k - 14

On dividing by 5 on both sides,

x = k - 14/5

Therefore, the value of x = k-14/5

Given:

y varies directly with x,

It is given that y = 7 when x = -9.

To find:

The value of y when x = 27 for the direct variation.

Solution:

It is given that y varies directly with x, so

[tex]y\propto x[/tex]

[tex]y=kx[/tex]             ...(i)

Where, k is the constant of proportionality.

It is given that y = 7 when x = -9. Putting these values in (i), we get

[tex]7=k(-9)[/tex]

[tex]-\dfrac{7}{9}=k[/tex]

Putting [tex]k=-\dfrac{7}{9}[/tex] in (i), we get

[tex]y=-\dfrac{7}{9}x[/tex]

Putting [tex]x=27[/tex],  we get

[tex]y=-\dfrac{7}{9}(27)[/tex]

[tex]y=-21[/tex]

Therefore, the required value is [tex]y=-21[/tex].

Answer:

The radius of the cylinder is 2.52 cm.

Step-by-step explanation:

The formula for the volume of a cylinder of radius r and height h is

V = πr²h.  We can solve this for r² by dividing both sides of the equation by πh:

r² = V / (πh)

Then the desired radius is found by taking the square root of this.

r = √{V / [πh]}

                  200 cm^2

Here, r² = ------------------- = 6.37 cm^2

                   3.14(10 cm)

and so r = √6.37 cm^2 = 2.52 cm

The radius of the cylinder is 2.52 cm.

Answer:

radius = 2.52 cm

Step-by-step explanation:

[tex]Volume = \pi r^2 h\\\\200 = \pi r^2 \times 10\\\\\frac{200}{10 \times \pi} = r^2 \\\\6.332 = r^2 \\\\\sqrt{6.332} = r \\\\r = 2.52 \ cm[/tex]

The mistake is that it is 1/16 not 16. The person probably did the reciprocal or incorrectly used the fraction

Answer:

The exponent for the answer should be -2. Therefore, the answer will be 4⁻² or 1/16.

Step-by-step explanation:

When dividing fractions, you subtract the exponents as long as they have the same base.

Since the exponents both have the base of 4, subtract 9 - 11.

9 - 11 = -2

The exponent would be -2 and the answer would be 4⁻².

When an exponent is negative, you take the inverse of the base raised to the positive exponent.

Since 4² = 16 or 16/1, 4⁻² would be 1/16.

The answer would be 4⁻² or 1/16.

Hope that helps.
