Answer:

ross-multiplication.

circumference divided by the diameter

10/x = 580/185

10x185=1850

1850/580=3.189

Answer:

7 feet.

Step-by-step explanation:

<u>Solve</u>

  • Set up a proportion using the given information for the turbine and its model.

C /d =  

C /d

  • Set up a proportion.

660 /210 =  

22/ d

  • Substitute the given values.

660 ÷ 30

210 ÷ 30  ≈  

22/ d

Since 660 divided by 30 is approximately 22, divide 210 by 30 to find the value of d.

660 /210  ≈  

22/ 7

 d ≈ 7

The diameter of the model is approximately 7 feet.

nadya68 [22]

Answer:

y = 4x +1

Step-by-step explanation:

6x + 1 = y + 2x

First you need to solve for y, so then you need to

1. Combine like terms

So since there isn't anything to combine we can more on.

2. Make Y by itself

You need to subtract the 2x from both side to get the answer

y = 4x +1

Ming wants to make a 40% sugar solution. She had already poured 3 L of a 80% sugar solution into a beaker. How many L of a 10% s
jeyben [28]

Answer:

Ming must add 0.375 L of a 10% sugar solution

Step-by-step explanation:

if 3 L = 80%

1.5 L should = 40% (since it is half of 80%)

and if 40 divided by 4 = 10%

1.5 also needs to be divided by 4

so 1.5 divided by 4 = 0.375

that means Ming must add 0.375 L of a 10% sugar solution

Stolb23 [73]

Answer:

v=a+ 2e1= [3 1 1 1] x^{T}.

Step-by-step explanation:

Let a = ^{}\left[\begin{array}{ccc}\\1&1&1\\\end{array}\right] ^{T}and we know that\alpha=±║α║₂= 2.

As we have gone over in class, the formula for v is v= a-\alphae1

with the sign of chosen to avoid subtraction. This gives v=a+ 2e1= [3 1 1 1] x^{T}.

Disclaimer ;The question is incomplete

Question:

Determine the Householder transformation that annihilates all but the first entry of the vector[1 1 1 1]>Specifically, if
