Answer:

Planet A is an outer planet, and planet B is an inner planet. Inner planets rotate slowly, so they take more time to complete a rotation. Outer planets rotate faster, so they take less time to complete a rotation.

What is a counterexample for "subtraction of whole numbers is commutative" ??

devlian [24]

The commutatice property for addition says a+b=b+a
If it was for subtraction, then it would be a-b=b-a
Take a=7 and b=5
7-5 is not equal to 5-7
2 is not equal to -2
So subtraction is not commutative for whole numbers.

Hope this helps :)

Ms. Melcher plans to decorate her house. Ms. Melcher wants to buy a rug to cover her bed room floor. If Ms. Melcher's bed room i

Marrrta [24]

The area of a square or a rectangle (which is the shape of any room in a house) is:

Area = width x length

So, in this case:

Area = 51 m x 26 m = 1326 Sq meters. Which is pretty big if you ask me.

Anyhow, Ms Melcher needs to buy 1326 sq meters

Which of the following is the equation of a line perpendicular to the line

Taya2010 [7]

Answer:

A. - 2x + 3y = 21

Step-by-step explanation:

The perpendicular lines have opposite reciprocal slopes.

<u>The given line has a slope of:</u>

m = -3/2

<u>The perpendicular slope is:</u>

m = 2/3

<u>And its y-intercept is:</u>

9 = 2/3*3 + b
b = 7

<u>The line is:</u>

y = 2/3x + 7

<u>Convert this into standard form and compare with answer choices:</u>

3y = 2x + 21
- 2x + 3y = 21

Correct choice is A

A figure is composed of a semicircle and a right triangle. Determine the area of the shaded region. Use 3.14 for π and round to

Aliun [14]

Answer:

$A=9.5\ ft^2$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of triangle plus the area of semicircle

so

$A=\frac{1}{2}bh+\frac{1}{2}\pi r^{2}$

we have

$b=4\ ft$

Find the height of the right triangle applying the Pythagorean Theorem

$5^2=h^2+4^2$

$h^2=9\\h=3\ ft$

The radius of the semicircle is half the height of triangle

$r=3/2=1.5\ ft$

substitute in the formula

$A=\frac{1}{2}(4)(3)+\frac{1}{2}(3.14)(1.5)^{2}$

$A=6+3.5=9.5\ ft^2$

PLEASE HELP, WILL GIVE BRAINLIEST IF CORRECT!!!! (08.06 MC) Mike and his friends bought cheese wafers for $2 per packet and choc

maks197457 [2]

Answer:

x = 5 , y = 15

Step-by-step explanation:

You can solve this using substitution.

Let the quantity of cheese wafers be denoted by x and the quantity of chocolate wafers denoted by y

2x + 1y = 25

x + y = 20

These two equations are the answer to part A, (remember to include the above prompt which says what x and y denote).

For part B I used substitution because it was more applicable to the question then addition or elimination.

ACTUAL WORK

Set 2x + 1y = 25 equal to x

x = 25 - y / 2

Replace x with y in the second equation

(25 - y / 2) + y = 20

And solve for y

y = 15

Since we know what y is we can replace y in the second equation and find what x is

x + 15 = 20

Solve for x

x = 5
