Each Pair Of Figures Below Is Similar. Find The Lengths Of The Unknown Sides That Are Marked With A Variable

Answers

Answer 1

The lengths of the unknown sides that are marked with a variable are;

a. x = 24

   y = 10

b. x = 5

Properties of similar triangles.

When on comparing the corresponding sides of two or more triangles, they are said to be similar if they have some common properties.

To find the lengths of the unknown sides that are marked with a variable, we have;

a. To determine the value of y,

21/ y = 15/ 21

cross multiply to have

15y = 21 * 21

     = 441

y = 441/ 15

  = 29.4

y = 24

ii. To determine the value of x,

25/ (25 + x) = 15/ 21

cross multiply

15(25 + x) = 25 * 21

375 + 15x = 525

15x = 525 - 375

      = 150

x = 150/ 15

 x = 10

b. 5/ 6 = 4.2/ x

6*4.2 = 5x

25.2 = 5x

x = 25.2/ 5

  = 5.04

x = 5.0

What is 1 more than 99?.

Answers

The Number which is more than 99 is 100.

Number:

Numbers are mathematical objects used for counting, measuring, and labeling. The original example is the natural numbers 1, 2, 3, 4, etc. [1] Numbers can be linguistically represented by numerals. More generally, individual numbers can be represented by symbols called digits. For example, "5" is the number representing the number five. Since only a relatively small number of symbols can be remembered, basic numbers are usually organized into number systems, which are systematic ways of representing each number. The most common number system is the Hindu-Arabic number system, which can represent any number using combinations of 10 basic numeral symbols called digits.

Greater than Number:

Greater than or equal to in mathematics is an inequality used to compare two or more numbers, quantities, or values. Used when one quantity or number is greater than or greater than the second or remaining quantity or number. This indicates that one value is greater than or greater than or greater than the other. The above symbol is ">". This is also called greater than.  For example, Bella has a red pencil that is 5 cm long and a blue pencil that is 3 cm long.

According to the Question:

1 more than 99 is:

adding 1 +99 = 100.

Is an example of distributive law *?.

Answers

Yes, 3 * ( 5 - 2 ) = ( 3 * 5 ) - ( 3 * 2 ) is an example of distributive law.

The distributive property is also known as the distributive law of multiplication over addition and subtraction. The name itself implies that the operation involves dividing or distributing something. The distributive law applies to addition and subtraction. The formula for the distributive property is expressed as:

Over addition : a( b + c ) = ab + ac

and subtraction : a( b - c) = ab - ac

Example: Solve the expression 7(20 + 3)

Multiplication of 7(20) and 7(3) is done before addition. This leads to 7(20) + 7(3) = 140 + 21 = 161.We have, an expression 3×(5 - 2) =(3 × 5 ) - (3× 2 ).

Consider the left hand side, 3×(5 - 2)

=> 3× 5 - 3× 2 = 15 - 6 = 9

Now, the right hand side, (3 × 5 ) - (3× 2 ) => 15 - 6 = 9 = LHS

Hence, it is an example of distributive law.

The length of the line segment bridging two points on a plane is known as the distance between the points.

The formula to find the distance between the two points is usually given by d=√{(x₂-x₁)² + (y₂-y₁)²}.

Given:

Raul crosses Main Street when he walks home from school.

To find the first term can be calculated an = a1 + d(n - 1).

The difference between every two successive terms in a sequence is the same; this is known as an arithmetic progression (AP). It is possible to obtain a formula for the nth term of the AP using this kind of development. A good example of an arithmetic progression (AP) is the series 2, 6, 10, 14,..., which follows a pattern in which each number is created by adding 4 to the previous term. The nth term in this series equals 4n-2. You may get the terms of the series by changing the nth term to n=1,2,3,... i.e.,

first term = 4n-2 = 4 when n = 1 (1)

An angle has a length of 166.7°. The extra degree at 166.7 is 13.3

How Do I Find Additional Angles?We are aware that two angles are supplementary if their sum is 180 degrees. It is claimed that each angle is a supplement to another angle. In order to obtain an angle's complement, we can subtract an angle from 180 degrees. A typical circumstance is when they are on the same side of a straight line.In geometry, two angles are referred to as supplementary angles if their sum is 180 degrees. For instance, if A + B = 180°, then A and B are considered supplementary angles.Complementary angles always result in a straight angle when combined (180 degrees).

Given,

The measure of an angle is 166.7°.

Answers

The density is 12.5 grams per cubic centimeter and 80 grams per cubic centimeter.

What is the density?

Density is a measure of how much mass is contained in a given volume. It is defined as the ratio of mass to volume and is typically measured in units of grams per cubic centimeter (g/cm^3) or kilograms per liter (kg/L).

The mass is 500 grams and the volume is 40 cubic centimeters, therefore the density is:

density = mass / volume = 500 grams / 40 cubic centimeters = 12.5 grams per cubic centimeter

The mass is 125 grams and the volume is v cubic centimeters. To find the value of v, you can use the equation:

density = mass / volume = 125 grams / v cubic centimeters

so v = mass / density = 125 grams / 12.5 grams per cubic centimeter = 10 cubic centimeters

The volume is 1.4 cubic centimeters and the density is 80 grams per cubic centimeter. To find the mass you can use the equation:

mass = density x volume = 80 grams per cubic centimeter x 1.4 cubic centimeters = 112 grams

But taxonomists, as organized as they may be, have no idea how many species Earth has. Nor can they even provide an educated guess. Although reporting over 16,000 new species every year, taxonomists still cannot predict how many more are undiscovered.In total, taxonomists have categorized and listed 1.2 million species on Earth. At this point, you would think scientists should be able to use the information they have gathered to make good predictions about how many species an ecosystem can support. This would help them make better predictions about how many species are left to identify. So far, however, the guesses seem to vary so greatly that it seems there is no good theory for making a prediction.One of the main problems is that most of the places that seem to have a lot of diverse species are in places that are hard to get to. One such place is the ocean, where scientists believe some 80 percent of Earth's creatures are hiding at depths too deep for us to study. In addition, many of the planet's most diverse areas are in remote places with few taxonomists.Despite all the unknowns, scientists have agreed that there are between five and 15 million species left to discover on Earth. This is a huge range, but whether it's five or 15, taxonomists clearly still have a lot of work to do. And who knows, there may yet be a dragon or a Loch Ness monster left to discover.Which of the following best paraphrases the paragraph in bold?

Also, the planet has diverse areas with remote places. Scientists have difficulty finding and identifying over three-quarters of the world's species due to their habitats being out of human reach.
