Answer:
− 11 Integers
2.45 Rational Number
1 Natural Number ( whole number)
− 11/7 Rational Number
Step-by-step explanation:
Natural numbers are numbers which are positive numbers i.e these do not include negative numbers and can be counted such as 1,2,3,4,5------ .Natural numbers do not include a zero.
Whole numbers are natural numbers but these include a zero e.g 0,1,2,3,4,5------
Integers are whole numbers but can be negative as well.
Rational Numbers are numbers in the form of p/q where q ≠0

Find JK................
Answer:
24 unit
Step-by-step explanation:
From the question,
JK = 2×NK.................... Equation 1
Using pythagoras theorem,
a² = b²+ c²................. Equation 2
From the diagram,
a = 15 unit, b = 9 unit, and c = NK
Substitute these values into equation 2
15² = 9²+(NK)²
Solve for NK
225 = 81+(NK)²
(NK)² = 225-81
(NK)² = 144
NK = [tex]\sqrt{144}[/tex]
NK = 12 unit.
Substitute these value of NK into equation 1
JK = 2×12
JK = 24 Unit.

Use the following diagram to find the angle measures of the triangle, rounded to the nearest degree.
m∠A=
m∠B=
m∠C=
Answer:
m∠A = 30°
m∠B = 80°
m∠C = 70°
Step-by-step explanation:
By applying cosine rule in the given triangle,
b² = a² + c² - 2ac[cos(∠B)]
From the given triangle,
a = 14 m
b = 28 m
c = 24 m
(28)² = (14)² + (24)² - 2(14)(24)cos(B)
784 = 196 + 576 - 672cos(∠B)
cos(∠B) = 0.1786
∠B = [tex]\text{cos}^{-1}(0.1786)[/tex]
∠B = 79.71°
∠B = 80°
By applying sine rule in the given triangle,
[tex]\frac{\text{sinA}}{a}= \frac{\text{sinB}}{b}= \frac{\text{sinC}}{c}[/tex]
[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}= \frac{\text{sinC}}{24}[/tex]
[tex]\frac{\text{sinA}}{14}= \frac{\text{sin(79.71)}}{28}[/tex]
[tex]\text{sinA}= \frac{\text{sin(79.71)}\times 14}{28}[/tex]
sinA = 0.491958
A = 29.47°
A ≈ 30°
By applying triangle sum theorem,
m∠A + m∠B + m∠C = 180°
30° + 80° + m∠C = 180°
m∠C = 70°
Neil has 3 partially full cans of white paint. They contian 1/3 gallon, 1/5 gallon and 1/2 gallon of paint. About how much paint does neil have
Answer:
1 1/30 gallon
Step-by-step explanation:
Can A = 1/3 gallon
Can B = 1/5 gallon
Can C = 1/2 gallon
Total paint Neil has = Can A + Can B + Can C
= 1/3 + 1/5 + 1/2
The lowest common multiple of 3, 5 and 2 is 30
= (10+6+15) / 30
= 31/30
= 1 1/30 gallon of paint
Neil has a total of 1 1/30 gallon of paint

what is 23 – 7x + 6 + 8x = 26
Answer: x = -3
Step-by-step explanation: hope this helps
23 – 7x + 6 + 8x = 26
x + 29 = 26
x + 29 - 29 = 26 - 29
x = 26 - 29
x = -3
Answer:
x=-3
Step-by-step explanation:
23 – 7x + 6 + 8x = 26
Add the numbers to get,
29-7x+8x=26
Move the constant to the right,
29+x=26
Add the numbers to get,
x=26=29
Calculate the difference
x=26-29
Calculate,
x=-3

A sales team estimates that the number of new phones it will sell is a function of the price that it sets. It estimates that if it
sets the price at x dollars, it will sell f(x) = 4,920 - 6x phones. Therefore, the company's revenue is x . (4,920 - 6x). Find
the price x that will maximize the company's revenue.
Answer:
410
Step-by-step explanation:
Revenue is given by the relation :
x . (4,920 - 6x)
F(x) = 4920x - 6x²
To obtain the price, x which maximizes revenue, we take the first derivative of the revenue function and equate to 0
F'(x) = 0
F'(x) = 4920 - 12x
4920 - 12x = 0
-12x = - 4920
x = 4920 / 12
x = 410
Price will be 410

m<10 = 97
m<9 = 83
m<5 = 97
m<7 = 83
m<16 = 97
Step-by-step explanation:
m<3 = m<2 because of vertical angles
m<10 = m<2 because of corresponding angles
m<9 + 97 = 180
m<9 = 83
m<5 + 83 = 180
m<5 = 97
m<7 = m<6 because of vertical angles
m<16 = m<5 because of alternate exterior angles.

A number that can be made by dividing two integers (an integer is a number with no fractional part). The word comes from "ratio". But π (pi) is not a rational number, it is an "Irrational Number".
Step-by-step explanation:
mark me please
Answer:
Since rational numbers are all numbers that can be written as a fraction, and includes positive numbers, negative numbers and the 0. We can conclude that since -3.4 can be written as a fraction it is a rational number.

Answer :
$38 + $2(n) where n is the no. of cars.
Step-by-step explanation:
He earns $38 daily which is fixed and additional $2 wage depends on the no. of cars which means no. of cars will determine how many $2's he earns.
25 cars = $38 + $2 (25) = $88
30 cars = $38 + $2 (30) = $98
35 cars = $38 + $2 (35) = $108
40 cars = $38 + $2 (40) = $118
