It takes40/ 13 or approximately 3.1 hours to do the job with both printers working on it.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given:

It takes an old printer 8 hours to print all the pictures for the yearbook.

A modern printer can do the same job in 5 hours.

If both work together,

it will take,

x(1/8 + 1/5) = 1

x(8 + 5)/40 = 1

8x + 5x = 40

x = 40/13

x = 3.07

x = approximately 3.1 hours.

Therefore, the work will be done in 40/13 hours.

Answer: C.Neither; the ratios are equivalent

Step-by-step explanation:

Kira spent 15 hours watching T.V and 12 hours reading. The ratio of time spent watching T.V. to time spent reading will be:

= 15/12

= 5/4

= 5:4

Charlie spent 20 hours watching T.V. and 16 hours reading. The ratio of time spent watching T.V. to time spent reading will be:

= 20/16

= 5/4

= 5:4

Therefore, they have equivalent ratio

[tex]\Huge\boxed{D.135 cm^3}[/tex]

Step-by-step explanation:

Hello There!

We can find the volume of the figure by using the formula for volume of a rectangular prism

[tex]V=lwh[/tex]

where l = length, w = width and h = height

we are given all of the dimensions so all we have to do is plug in the values

so

V = 3 x 9 x 5

3x9=27

27x5=135

so the volume of the rectangular prism is 135 cm³

The length of the diagonal drawn by Leah will be 50 feets

Given the Parameters :

The length of the diagonal is the value of the hypotenus in a right angles triangle :

Let the length of the diagonal = d

d = √(length)² + (width)²

d = √48² + 16²

d = √2304 + 256

d = √2560

d = 50.5961 feets

Therefore, the closest value for the length of the diagonal in the options given is 50 feets

Answer:

11 and 14

Step-by-step explanation:

t can be 7 or 8

7+5=12

8+5=13

12 and 13 are between 11 and 14

The number t + 5 is in between 11 and 14.

"It is a mathematical statement of an order relationship (greater than, greater than or equal to, less than, or less than or equal to) between two numbers or mathematical expressions."

" Let x, y, and z be real numbers.

If x > y, then x + z > y + z."

For given question,

t is a number between 6 and 9.

So, we have an inequality.

⇒ 6 < t < 9

By addition property of inequality,

⇒ 6 + 5 < t + 5 < 9 + 5

⇒ 11 < t + 5 < 14

Therefore, the number t + 5 is in between 11 and 14.

Answer:

The equations that represent an exponential decay are;

A; [y = (0.1)ˣ]

B; [y = 2·(0.3)ˣ]

Step-by-step explanation:

An exponential decay is given by the following formula;

y = a·bˣ

Where;

b < 1

For option A, we have; [y = (0.1)ˣ]

Here; a = 1, b = 0.1 < 1, therefore, the function represents an exponential decay

For option B, we have; [y = 2·(0.3)ˣ]

Here; a = 2, b = 0.3 < 1, therefore, the function represents an exponential decay

For option C, we have; [tex]\left[y = \left(\dfrac{4}{3} \right)^x\right][/tex]

Here; a = 1, b = [tex]\dfrac{4}{3} \right) > 1[/tex], therefore, the function does not represent an exponential decay

For option D, we have; [tex]\left[y = \left(\dfrac{7}{5} \right)^x\right][/tex]

Here; a = 1, b = [tex]\dfrac{7}{5} \right) > 1[/tex], therefore, the function does not represent an exponential decay
