Find The Missing Side:Whats The Missing Side

Answers

Answer 1

Answer:

B

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 13² + 4² = 169 + 16 = 185 ( take the square root of both sides )

x = [tex]\sqrt{185}[/tex] ≈ 13.6 ( to 1 dec. place ) → B

Why does x^4 * x^-4 = 1?

Answers

Answer:

Step-by-step explanation:

when you have a negative exponent, you are going to have a fraction. Example: 2^4 * 2^-4= 2^4 is 16 2^-4 is 1/16.

You get the 16 but because it was a negative exponent, the 16 goes on the bottom. 16 as a fraction is 16/1.

When you multiply 16/1 and 1/16. It comes up to 16/16 or 1.

Does this help?

Answer:

below

Step-by-step explanation:

We can use the product rule of exponents to solve [ x^y * x^z = x^y+z ].

x^4 * x^-4 = 1

x^4+(-4) = 1

x^0 = 1

1 = 1

The lines represented by the equations 20y-24x=-20y and 5y-6x=-5 are

a) perpendicular
b) the same line
c) neither parallel nor perpendicular
d) parallel

Answers

Answer:don’t listen to the other guy he’s wrong. The answer is the same line.

Step-by-step explanation:

20y-24x=-20 add 24x to both sides

20y=24x-20

Divide 20 to all

New equation is

Y=5/6x-1

Now let’s solve for 5y-6x=-5

Add 6x to both sides

5y=6x-5

Divide 5 to all

The new equation is

Y=6/5x-1

As you see they have the same equation so the answer is that the lines are the same :) have a good day guys hope this helped <3

Are tax rates different than sales tax? I forgot and I'm doing my math homework. If anyone could help, that would be great!:)

Answers

Some local jurisdictions do not impose a sales tax. 7.250% Note that the true California state sales tax rate is 6%. There is a statewide county tax of 1.25% and therefore, the lowest rate anywhere in California is 7.25%. We have listed the combined state/county rate as the state rate to eliminate confusion.

2. Lin's family has completed 30% of a trip. They have traveled
60 miles. How far is the trip? (Hint: You can use a tape diagram,
Highlight the answer that shows how far Lin's family trip is. (2 points)

Answers

Answer:

1. D) 17%

2. 200 miles

Step-by-step explanation:

For the first question we can turn the information into a fraction, with the total number of pieces of fruit in the bowl (12) as the denominator and the number of apples (2) as the numerator.

[tex]\frac{2}{12}[/tex]

Then, divide:

2/12 = 0.17 = 17%

For the second question, we set up a proportion. We know that 60 miles corresponds to 30% and the whole distance of the trip, x, corresponds to 100%

[tex]\frac{60}{x} = \frac{30}{100}[/tex]

Cross multiply and solve:

60 * 100 = 30x

6000 = 30x

200 = x

Sophia is making tomato sauce. She adds 12 grams of her secret ingredient to each liter of sauce she prepares. If she has 4 grams of her secret ingredient, how many liters of sauce can she make?
​

Answers

Answer:

[tex]\frac{1}{3}[/tex]liter

Step-by-step explanation:

To make her tomato sauce,

  Sophia adds 12g to 1 liter of sauce;

Let us find the;

  liter of sauce per gram of ingredient = [tex]\frac{1}{12}[/tex]liter/gram

Now;

  liters of sauce required to make 4grams

   liter of sauce  = 4g x  [tex]\frac{1}{12}[/tex]liter/g = [tex]\frac{1}{3}[/tex]liter
