Last month, Kira spent 15 hours watching T.V. And 12 hours reading. During the same month, Charlie spent 20 hours watching T.V. And 16 hours reading. Who had a higher ratio of time spent watching T.V. To time spent reading?​ A. Kira B.Charlie C.Neither; the ratios are equivalent

Answers

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

Answer:

409 = 223 + z

z = 186

Step-by-step explanation:

We know Tyler is 223 - z or z + 223

409 = 223 + z

409 = z + 223

409 - 223 = z + 223 - 223

186 = z + 223 - 223

distributive property

Answer:

x = 18/45 (or, in a decimal, 0.4). Someone correct me if I'm wrong. :)

Step-by-step explanation:

We have to use the distributive property here. That means that you multiply -5x by 9 and -2 by 9. So...

9*-5x = -45x

9*-2 = -18

-45x = -18

Now, divide both sides by 45...

-45x/45 = -18/45

x = 18/45 should be the 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

Leah's rectangular driveway is 48 feet long and 14 feet wide. With sidewalk chalk, Leah drew a straight diagonal line on her driveway from one corner to the opposite corner.

How long is the diagonal line Leah drew?

25 feet

46 feet

50 feet

62 feet

Answers

[tex]48^2+14^2=x^2\\x^2=2500\\x=50[/tex]

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

Given the Parameters :

Length = 48 feet Width = 14 feets

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

what is the volume of the rectangular prism​

Answers

It is all the numbers multiplied together. 135

Answer:

[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
