20 multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180.

if the sum of its digits is divisible by 9 or if tje sum is a mutiple of 9, then the number is divible by 9.

add up the digits and figure out if the sum if the digits is a multiple of nine or weather its divisble by 9

Answer:

9 x 1         9

9 x 2 18

9 x 3 27

9 x 4 36

9 x 5 45

9 x 6 54

9 x 7 63

9 x 8 72

9 x 9 81

9 x 10 90

9 x 11 99

9 x 12 108

9 x 13 117

9 x 14 126

9 x 15 135

9 x 16 144

9 x 17 153

9 x 18 162

9 x 19 171

9 x 20     180

Step-by-step explanation: Divisibility Rule of 9

That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9. Example: Consider 78532, as the sum of its digits (7+8+5+3+2) is 25, which is not divisible by 9, hence 78532 is not divisible by 9.

The solution for the given expression 11a³b⁰ is 88.

Power implies a number is multiplied how many times by itself. If a is any positive number and n is its power , then aⁿ means a is multiplied by itself n times

The given expression is,

11a³b⁰

Also given that,

The value of a=2 and b=-8,

Substitute the value of a and b in expression 11a³b⁰,

11×2³×(-8)⁰

⇒11×8×1  (Since,  a⁰=1)

⇒88.

The value of expression 11a³b⁰ is 88.

Answer:

The answer is 80 ft

Step-by-step explanation:

Based on the diagram we know that the tree triangle and the building triangle are similar triangles where the lengths of each are proportional to the other. 

The lengths of the triangle the tree makes are half of the lengths of the building triangle.

So this problem can be solved using ratio and proportion:to solve for x, all you need to do is cross multiply then divide. The answer is then 80ft.Another way to solve this is just by using logic. If the lengths of the tree triangle is half of the building, simply divide the lengths of the building triangle by two. 160ft/2 = 80ft.

Step-by-step explanation:

9. x°=90°-30°=60°

10. x°=180°-(40°+65°)=180°-105°=75°

11. x°=180°-(35°+45°)=180°-80°=100°

12. x°=180°-(25°+x°+65°)

x°=180°-90°-x°

2x°=90°

x°=45°; (x+65)°=110°

13. x°=180°-(48°+x°-44°)

x°=180°-4°-x°

2x°=176°

x°=88°; (x-44)°=44°

Out of the given integer(s), {4} is the integer which will make the inequality 4x + 6 < 2x + 12 false.

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions unequally.

Based on the question, we are supposed to determine which integer will make the inequality  4x + 6 < 2x + 12 false

Let's solve the inequality for the range of x first;

4x + 6 < 2x + 12

4x - 2x <  + 12 - 6

2x < 6

x < 3

So for all values of x < 3, the inequality  4x + 6 < 2x + 12 is true and for all values of x > 3, the inequality 4x + 6 < 2x + 12 false.

Hence, we accept {4} as our required integer.

The simplification of x raised to the negative seventh power over y raised to the fifth power will be  1/x⁷y⁵.

A mathematical expression is a phrase that has a minimum of two numbers or variables and at least one mathematical operation. It is possible to multiply, divide, add, or subtract in math. An expression has the following structure: (Mathematical Operator, Number/Variable, Expression)

It is given that the expression is, "x raised to the negative seventh power over y raised to the fifth power."

The expression can be written as,

=x⁻⁷/y⁵

= 1/x⁷y⁵

Thus, for the given expression the simplification is obtained as, 1/x⁷y⁵

The solution to inequality is p ≤ 3.7 or p ∈ (-∞, 3.7] and it will be on a number line with a closed circle plotted at 3.7, and the arrow pointing left option (B) is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

It is given that:

The inequality is:

−3p + 6.7 ≥ −4.4

After solving the above inequality:

−3p  ≥ −4.4 - 6.7

-3p  ≥ -11.1

p ≤ 3.7

Thus, the solution to inequality is p ≤ 3.7 or p ∈ (-∞, 3.7] and it will be on a number line with a closed circle plotted at 3.7, and the arrow pointing left option (B) is correct.

The quotient in simplest form is given as follows.

For every pair of integers a, b where b≠0, there exist unique integers q, r such that -

a = q x b + r

and

0 ≤ r < |b|

where -

[a] is the dividend.

[b] is the divisor.

[q] is the quotient.

[r] is the remainder.
