What is 1 more than 99?.
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.

Are 1 3 and 2 7 equivalent fractions?.
No, 1/3 and 2/7 are not the equivalent fractions.
In mathematics, equivalent fractions are those with the same denominator and differing numerators. For instance, because 2/4 and 3/6 are both equal to 1, they are both comparable fractions. Part of a whole is a fraction. Identical portions of the whole are represented by equivalent fractions.
Every fraction has an equivalent fraction, which can be found by multiplying the numerator and denominator by the same integer. In spite of their visual differences, equivalent fractions are those that indicate the same value. For instance, if you take a piece of cake, divide it into two equal pieces, then eat one of them, you will have consumed half of the cake.
let us consider,
1/3 = 2/7
0.33 = 0.29

Assertion : If both zeros of the quadratic polynomial x k2 2 x 2 − + are equal in magnitude but opposite in sign then
value of k is ½.
Reason : Sum of zeros of a quadratic polynomial ax bx c 2 + + is a
-b
The assertion that both zeros of the quadratic polynomial x² - 2kx +2 in magnitude but opposite in sign then value of k is 1/2 is false.
How to obtain the sum of the roots of the quadratic function?The standard definition of a quadratic function is given as follows:
y = ax² + bx + c.
The sum of the roots of a quadratic function is given as follows:
S = -b/a.
The equation in this problem is given as follows:
x² - 2kx +2
Hence the parameters are:
a = 1, b = -2k.
If the roots are equal in magnitude but the opposite sign, the sum of the roots is of:
0.
Hence:
-b/a = 0.
b = 0.
Meaning that the value of k is obtained as follows:
-2k = 0.
k = 0.

One rule of thumb for estimating crowds is that each person occupies 360 square inchesUse this rule to estimate the crowd size of a section that is 20 feet deep by 20 feet wide of a parade route. HINTthere are 12 inches in one foot
Therefore , the solution of the given problem of surface area comes out to be 160 peoples can be fit in that region.
Surface area is definedIts surface area is a good indicator of how much space it takes up overall. When estimating the surface area of a three-dimensional shape, the entire environment is taken into consideration. Its surface area determines how big something is overall. The sum of the faces on any and all six of a cuboid's rectangular sides yields the amount of water contained within.
Here,
Given : one person occupies 360 square inches
is 2.5 square foot.
So,
The given dimension of region are :
length = 20 feet and width 20 feet.
Thus,
=> Area = 20*20
=> Area = 400 square foot.
So , number of people in that area will be :

What is a 1/10 gradient?.
The 1/10 gradient means 6 degrees is the angle of 1 in 10 slopes.
The gradient is the inclination of a line. The gradient is often referred to as the slope (m) of the line. The gradient or slope of a line inclined at an angle θ is equal to the tangent of the angle θ.
In geometry, 1 in 10 means for every ten units of horizontal distance crosses there is 1 unit of vertical drop or rise. The angle of tan is used to measure this value of the slope. Let x be the angle to be used for tan.

Write an equation to represent the relationship between
the three quantities (density, mass, and volume) in each
situation.
Let the density, D, be measured in grams/cubic
centimeters (or g/cm3).
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

The credit utilisation ratio to the nearest percentage is found as 17%.
Define the term credit utilisation ratio?The proportion of a borrower's total credit available that is presently being used is known as the credit utilisation ratio. When determining a borrower's credit score, credit reporting companies take into account the credit utilisation ratio.Steps:
You must collect all of the credit cards in order to determine your credit utilisation ratio. Add the credit limits after adding up all the remaining balance. Your credit usage ratio is expressed as a percentage by taking the entire amounts, dividing them but by total credit limit, and thereafter multiplying the result by 100.For the stated question:
Balance = $180 + $230 = $410.
credit limits = $1500 + $1000 = $2500.
Credit utilisation ratio = Balance / credit limits
Credit utilisation ratio = 410 / 2500 * 100 = 16.4%

Is an example of distributive law *?.
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)

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.,
