Write an inverse variation equation that relates x and y. With x being 10 and y being 2
yulyashka [42]

Answer:x=20/y

Step-by-step explanation:

x α 1/y

removing the constant of proportionality sign α and replace it with =k

x = k/y

x=10 y=2

10 = k/2

Cross multiply

10x2=k

20=k

k=20

Substitute k=20 in x=k/y

x=20/y.........required equation

m∠WYX=(2x−1)° and m∠WYZ=(4x+1)°. If ∠WYX and ∠WYZ are complementary, what is the measure of each angle?
Neko [114]

We are given : m∠WYX=(2x−1)° and m∠WYZ=(4x+1)°.

∠WYX and ∠WYZ are complementary.

We know, sum of complementary angles is = 90°.

So, we need to add ∠WYX and ∠WYZ and set it equal to 90°.

m∠WYX + m∠WYZ = 90°.

Plugging values of ∠WYX and ∠WYZ in the above equation, we get

(2x−1)° + (4x+1)° = 90°.

Removing parentheses from both sides,

2x-1 + 4x+1 =90.

Combining like terms,

2x+4x= 6x and -1+1 =0

6x +0 =90.

6x=90.

Dividing both sides by 6.

6x/6 =90/6

x= 15.

Plugging value of x=15.

m∠WYX=(2x−1)° = 2*15 -1 = 30 -1 =29

m∠WYZ=(4x+1)° = 4*15 +1 = 60+1 = 61.

Therefore, ∠WYX=29° and ∠WYZ=61°.

Can someone take the time to answer this for me? I try to turn the feet into inches and then all the inches into feet but it doe
Mumz [18]
To find the equation, we first need to change the unit as you did correctly:

1 feet = 12 inches

In this case,let's turn the unit of depth to feet:

4÷12
= 1/3 feet

Then we can find the volume in inches:

1/3×162×6
=54×6
=324 ft^3

Therefore the answer is B.324 ft^3 .

Hope it helps!

Use mathematical induction to prove that the statement is true for every positive integer n. 8 + 16 + 24 + . . . + 8n = 4n(n + 1
mezya [45]
First show the statement holds for n=1. The left hand side is just 8, and the right hand side is 4(1)(1+1)=8, so it's true.

Assume the statement holds for n=k, i.e.

8+16+\cdots+8(k-1)+8k=4k(k+1)

and use this to show it holds for n=k+1, i.e.

8+16+\cdots+8(k-1)+8k+8(k+1)=4(k+1)(k+2)

By the assumption above, you have

\underbrace{8+16+\cdots+8(k-1)+8k}_{n=k}+8(k+1)=4k(k+1)+8(k+1)=4(k+1)(k+2)

so the statement is true for all n\ge1.
