A ____ is a pair of equal ratios.

Answers

A proportion  is a pair of equal ratios.

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

A proportion is a pair of equal ratios.

A proportion is an equation in which two ratios are set equal to each other.

Equivalent ratios are the ratios that are the same when we compare them

A proportion is a numerical correlation between two numbers. Frequently, these numbers can speak to an examination of things or individuals.

For instance, say you strolled into a room brimming with individuals.

Hence, a proportion  is a pair of equal ratios.

The average speed of a plane is 560 kilometers per hour. How long does it take the plane to travel 140 kilometers?

Answers

(140 km) x (1 hour / 560 km) = 0.25 hour = 15 minutes
560kph*x=140kilometers so x=.25 so .25*60 minutes is 15 minutes

What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8? an = 2(−8)n − 1; all integers where n ≥ 1 an = 2(−8)n − 1; all integers where n ≥ 0 an = 2(−4)n − 1; all integers where n ≥ 0 an = 2(−4)n − 1; all integers where n ≥ 1

Answers

Hello,

The question is
"What are the explicit equation and domain for a geometric sequence with a first term of 2 and a second term of −8?"

It is a geometric sequence =>U(2)=U(1)*r==>-8=2*r ==>r=-4

U(1)=2=2*(-4)^0
U(2)=-8=2*(-4)=2*(-4)^1
U(3)=32=-8*(-4)=2*(-4)(-4)=2*(-4)^2
U(4)=-128=32*(-4)=2*(-4)^3
...
U(n)=2*(-4)^(n-1) where n>=1.

Answer C

A quadrilateral has angles that measure 56°, 97°, and 136°.What is the measure of the fourth angle?

Answers

Angles of a quadrilateral add up to 360 degrees. Thus;
360-(56+97+136)
=71°
The sum of the interior angles can be represented by:
180(n-2)
180 x 2 = 360
Therefore, the sum of the angles must be 360.

56 + 97 + 136 = 289
360 - 289 = 71°

Otto used 6 cups of whole wheat flour and x cups of white flour in the recipe. What is the equation that can be used to find the value of y

Answers

Answer:

y = 6 + x

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

Assuming that the value of y is the total number of flour used in the mixture, then we would need to add both types of flour in order to find the value of y. Since we do not know the amount of white flour used, we will be substituting it for the variable x.

y = 6 + x

The Equation above is stating that 6 cups of whole wheat flour added to the amount of white flour will equal the total amount of flour in the mixture.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
