Katlin is choosing between two circular wall clocks one has the radius of 5 inches while the other one has a radius of 6 inches.How much more wall space will the clock with a radius of 6 inches cover?

Plz help i dont get any of these type of questions T-T

Answers

Answer:

Exact: [tex] 11 \pi~in.^2 [/tex]

Approximate: [tex] 34.6~in.^2 [/tex]

Step-by-step explanation:

The spaces the clocks occupy on the wall are the areas of the clocks.

The clocks are shaped like circles, so use the formula for the area of a circle to find the two areas. Then subtract the smaller area from the larger area.

[tex] A_{circle} = \pi r^2 [/tex]

Larger clock, r = 6 in.

[tex]A_{large~clock} = \pi \times (6~in.)^2 = 36 \pi ~in.^2 = 113.1~in.^2[/tex]

Smaller clock, r = 5 in.

[tex]A_{small~clock} = \pi \times (5~in.)^2 = 25 \pi ~in.^2 = 78.5~in.^2[/tex]

Difference in areas:

Exact: [tex] 36 \pi~in.^2 - 25 \pi~in.^2 = 11 \pi~in.^2 [/tex]

Approximate: [tex] 113.1~in.^2 - 78.5~in.^2 = 34.6~in.^2 [/tex]

Step-by-step explanation:

1200÷3=400

400×2=800

800 laptops

Answer:

800 Laptops

Step-by-step explanation:

3:2 = 1200:x

I first divide 1200 with 3 because that is the ratio of the students. WE can see that 1200/400 equals 3. So if I multiply 2 times 400, then we get 800 Laptops.

Help show work pls for brisnly

Answers

Answer:

6

Step-by-step explanation:

Ok, so all we have to do is multiply 8 * 3/4, because each child needs 3/4 of the sandwich, and there are 8 of them. The easiest (My opinion) way to do this is by turning 8 into a fraction. Turning whole numbers into fractions is really simple, just slap a /1 under them to make them a fraction. And so, our fraction is 8/1. Now, all we have to do is multiply the top part of the fraction, and then the bottom part of the fraction. So, 8 * 3 = 24, and 1 * 4 = 4. So, just put 24/4 as an answer. But, wait! We have to simplify it! 24 divided by 4 is 6, so 6 is our final answer.

The exponential form of equation log₈512 = 3 is 8³ = 512.

What is inverse form of Exponential Equation?

The inverse of the exponential function y = aˣ is x = [tex]a^{y}[/tex]. The logarithmic function y = logₐx is defined to be equivalent to the exponential equation is x = [tex]a^{y}[/tex].

Here,

log₈512 = 3 compare with  y = logₐx

we get, a = 8, x = 512, and y = 3

Now Exponent equation is x = [tex]a^{y}[/tex]

                                          512 = 8³

Thus, The exponential form of equation log₈512 = 3 is 8³ = 512.

if x = 3 and y=-4 find x2 + y2 and x2 -y2

Answers

1. Plug in the 3 in all the x’s that are in the equation:

(3)2 + y2 = for x2 + y2

(3)2 - y2 = for x2 - y2

This would get you for both equations..

6 + y2 = for x2 + y2

6 - y2 = for x2 - y2

2. Now let’s plug in the value of y which is -4:

6 + (-4)2 = for x2 + y2

6 - (-4)2 = for x2 + y2

This would get you for both equations...

-2 = x2 + y2

14 = x2 - y2
