Answer:

x = -1

Step-by-step explanation:

Given

(x - 5)(-3) = 18

Expand the bracket

x X -3 -5 x -3 = 18

-3x + 15 = 18

Subtract 15 from both sides

-3x + 15 - 15 = 18 - 15

-3x = 3

Divide both sides by -3

-3x/-3 = 3/-3

x = -1

The given pyramid's volume is 40 cubic units.

Step-by-step explanation:

Step 1:

It is given that base areas of the pyramid and the prism are the same. The height is also equal.

The rectangular prism's height is 15 units so as per the given question, the height of the pyramid is also 15 units.

Step 2:

The volume of this pyramid is obtained by multiplying [tex]\frac{1}{3}[/tex] with the product of the pyramid's length, width, and height.

For the given pyramid, length = 2 units, width = 4 units and the height = 15 units.

The pyramid's volume [tex]= \frac{1}{3} (length)(width)(height)[/tex] = [tex]\frac{1}{3} (2)(4)(15) = \frac{1}{3} (120)[/tex] = 40 cubic units.

So the volume of the given pyramid is 40 cubic units.

Step-by-step explanation:

To determine the percentage of the jury not over 35 years old, divide the number of jurors not over 35 by the total number of jurors (3/12) and then multiply by 100, resulting in 25 percent.

If nine out of twelve jurors are over 35, then three out of twelve jurors are not over 35. To find out what percentage of the jury is not over 35, we use the following calculation:

Therefore, 25 percent of the jury is not over 35 years old.

Answer: 0.6

Step-by-step explanation:

Total population of class = 50

There are 27 athletes, and 9 musicians However, 6 of the musicians are also athletes.

Therefore, totals for athletes and musicians are:

27 + 9 -6 = 30

Thus, the probability of choosing an athlete or a musician is 30/50= 0.6

We could also use the formula:

P(A or M) = P(A) + P(M) - P(A and M)

P(A or M)=27/50+9/50-6/50

P(A or M)=30/50=0.6

Decimal point moved 5 places to the right, since 10⁵ has 5 zeros in it.

Step-by-step explanation:

52.48 is multiplied by 10 to the power of 5, that is 100, 000, we will get ,

[tex]52.48 \times 10^{5}=5248000.00[/tex]

When 52.48 is multiplied by 100,000, we will get 5248 followed by 5 zeros, 524800000.

Now we have to count the decimal point from left to right, so we will get 5248000.00, zeros after the decimal point has no value.

The decimal point should be moved _5__ places to the right because there are _5__ zeros in 10 to the power of 5.

Answer:

1. The quadratic equation is 3x² +17.5x - 58.5 = 0

2. The values of x are 2.38 and -8.21, but we only take 2.38 for our problem.

3. The dimensions of the combined area are approximately 6.38 inches and 12.64 inches.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Photograph dimensions = 4 inches * 6 inches

Frame dimensions = x inches * 3x - 0.5 inches

Area of the combined area of the photograph and the frame = 80.5 inches²

2. Write a quadratic equation for the combined area. Then use the quadratic equation formula to find x.

One side of the combined area of the photograph and the frame = 4 + x inches

Second side of the combined area of the photograph and the frame = 6 + 3x - 0.5 inches

Now, we can write the quadratic equation this way:

Combined area of the photograph and the frame = One side * Second side, replacing with the values we know:

80.5 = (4 + x) * (6 + 3x - 0.5)

80.5 =  (4 + x) * (5.5 + 3x)

80.5 = 22 + 5.5x + 12x + 3x²

3x² +17.5x - 58.5 = 0

Using the quadratic formula, where, a = 3, b = 17.5 and c = - 58.5, we have:

x = (-b +/- √b² - 4ac)/2a

x = (-17.5 +/- √17.5² - 4 * 3 * -58.5) 2 * 3

x = (-17.5 +/- √306.25 + 702)/6

x = (-17.5 +/- √1,008.25)/6

x = (-17.5 +/- 31.75)/6

x₁ = 14.25/6 = 2.38

x₂ = -49.25/6 = -8.21

We took the value of x₁ because x₂ is negative and we can't have a negative value for the length or the width, therefore:

80.5 = (4 + x) * (5.5 + 3x)

Replacing x, we have:

80.5 = (4 + 2.38) * (5.5 + 3 * 2.38)

80.5 = 6.38 * 12.64

80.5 ≅ 6.38 * 12.64

Answer:

Option B, -4 and 4

Step-by-step explanation:

Step 1:  Subtract 15 from both sides

y^2 - 1 - 15 = 15 - 15

y^2 - 16 = 0

Step 2:  Factor

y^2 - 16

(y + 4)(y - 4)

Step 3:  Find the solutions

y + 4 - 4 = 0 - 4 and y - 4 + 4 = 0 + 4

y = -4 and y = 4

Answer:  Option B, -4 and 4

Answer:

-4 and 4

Step-by-step explanation:

All you need to do is solve for y

[tex]y^{2} - 1 = 15\\[/tex] (plus 1 to both sides)

[tex]y^{2} = 16[/tex] (take square root of 16)

[tex]y = \sqrt{16}[/tex]

[tex]y = +-4[/tex] (whenever you to the root of a perfect square you want the positive and negative root)

To double check if your answer is right: plug in -4 and +4 in as y and see if it equals 15

1. [tex](4)^{2} - 1 =15[/tex]

[tex]16-1 = 15\\15= 15[/tex]

(positive 4 checks out)

2. [tex](-4)^{2} - 1 = 15[/tex]

[tex]16 - 1 = 15\\15 = 15[/tex]

( negative 4 checks out)

f(-2) = 3/8

Step-by-step explanation:

f(x)=6•4^x

Let  x=-2

f(-2) = 6 * 4^-2

The negative in the exponent means it goes to the denominator

f(-2) = 6 * 1/ 4^2

       = 6/4^2

        =6/16

Simplifying

        =3/8

Answer:

Step-by-step explanation:

The age cullen is 5 yrs and Ada is 15 years old.

Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.

Given:

Cullen is 10 years younger than Ada.

The product of their ages 2 years ago was 39.

let the age of ada be x

Cullen's age = x- 10

22 years ago there age will be

Ada = x-22

Cullen = x-32

Now, the product of their age is 39

(x-2)(x-12)=39

x²-12x-2x + 24=39

x² -14x + 24=39

x² - 14x -15 = 0

x² -15x + x- 15=0

x(x-15) + 1(x-15)=0

(x-15)(x-1)=0

x= 15 or -1.

Hence, the age of Ada is 15 yrs and cullen age is 5.

Answer: OPTION B

Step-by-step explanation:

You can observe that the exercise provides you two Linear functions.

The first Linear function is the function f(x). This is:

[tex]f(x) = 2x+1[/tex]

And the other Linear function is the function g(x):

[tex]g(x) = x+14[/tex]

In order to find [tex](gof)(x)[/tex], you need to follow these steps shown below:

Step 1:

You must substitute the function f(x) into the function g(x); this means that the function f(x) will be in the place of the variable "x" of the function g(x); as you can observe below:

[tex](gof)(x) = (2x+1)+14[/tex]

Step 2:

Finally you must combine the like terms (You can notice that the like terms are 1 and 14; then you must add them). Therefore, you get that  [tex](gof)(x)[/tex] is:

[tex](gof)(x) = 2x+1+14\\\\(gof)(x) = 2x+15[/tex]
