Statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.
What is the number?A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
As we know,
The integer can be defined as the whole number it can be a negative whole number or a positive whole number for example 2, 4, 1, -8, 0, etc.
It is defined as the numbers in all real numbers which cannot be represented as rational numbers, in other words, the irrational number cannot be expressed in the form of p/q form.
A rational number is a sort of real number that has the form p/q and does not equal zero.
Thus, statements (1), (3), and (4) are correct these are NOT true after using the definition of the numbers.

home, and $60 an hour for work. This is modeled by
C (2) = 35+ 60x . Explain what C (5) = 335 means in terms of total cost and
number of hours.
help plz
Answer:
Step-by-step explanation:
Total cost
C (x) = 35+ 60x
Where,
Fixed cost= $35
Variable cost = 60x
x= number of hours of work
Total cost is the addition of fixed and variable cost
C (x) = 35+ 60x
C(5)= 35 + 60(5)
= 35 + 300
=335
C(5) = 335
C(5) = 335 is Olivia's total cost of hiring the electrician
x=5 is the electrician's number of hours of work
35= fixed cost of hiring the electrician
60(5) = 300 is the variable cost of hiring the electrician for 5 hours

Please save for x the. The perimeter
Answer:
x = 1
Step-by-step explanation:
The perimeter of the square is 4(2x + 3) = 8x + 12 and the perimeter of the triangle is 3x + 2(x + 3) + 5x + 4 = 10x + 10. Since they are equal, we can write:
8x + 12 = 10x + 10
-2x = -2
x = 1
Answer:
x =1Step-by-step explanation:
Perimeter of a square = 4(a)
Where a = side=2x+3
[tex]P = 4(a)\\P= 4(2x+3)\\Perimeter \: = 8x +12[/tex]
Perimeter of a triangle =

0.5x-7= 0.3 solve the equation
Answer:
[tex] \boxed{ \bold{ \boxed{ \sf{x = 14.6}}}}[/tex]Step-by-step explanation:
[tex] \sf{0.5x - 7 = 0.3}[/tex]
Move 7 to right hand side and change it's sign
⇒[tex] \sf{0.5x = 0.3 + 7}[/tex]
Add the numbers
⇒[tex] \sf{0.5x = 7.3}[/tex]
Divide both sides of the equation by 0.5
⇒[tex] \sf{ \frac{0.5x}{0.5} = \frac{7.3}{0.5} }[/tex]
Calculate

In between what two integers is the \large \sqrt{77}
Answer:
8 and 9
Step-by-step explanation:
Since 77 is between 64= 8² and 81= 9²
√64 < √77 < √818 < √77 < 91 Let a = 5.2 and b = 4.7.
a Find the exact value of 3a + b3.
Xena estimates that the answer to part a is 140.
b Find the percentage error made by Xena in her estimation.
Part (a)
Replace every 'a' with 5.2 and replace every 'b' with 4.7
Then use your calculator to evaluate.
3a + b^3 = 3*5.2 + (4.7)^3 = 119.423
Answer: 119.423===============================================
Part (b)
The true value is 119.423 which is the result of part (a)
The estimated value is 140
Subtract the two values
140-119.423 = 20.577
and divide that over the true value
20.577/140 = 0.14697857142858
Which, when rounded to 4 decimal places, we get 0.1470
Move the decimal place over to the right 2 spots to get 14.70%

f(g(x)) = 2x +(-5)
After Luca took his dogs for a walk, he gave them 6 dog treats. When Luca's dad got home from work, he gave the dogs t more treats. All together that day, Luca's dogs got 10 dog treats. Write an equation to describe this situation. How many dog treats did Luca's dad give the dogs?
Answer:
6 + t= 10
4 dog treats
Step-by-step explanation:
Luca took his dogs out for a walk.
He gave his dogs 6 dog treats.
Luca's dad came back home that same day and gave the dogs "t" more treats
This means "t" more treats added to the initial 6 treats.
6 + t
All together that same day, Luca's dogs got a total of 10 treats
6 + t = 10
Hence the equation to describe this situation can be written as 6 + t= 10
The number of treats that Luca's dad gave to the dogs can be calculated as follows
6 + t= 10
t = 10-6
t= 4
Hence the number of treats that Luca's dad gave to the dogs is 4 treats

Gina gets money from her grandfather every day for the entire week of her birthday, starting on Monday. She gets $2 on Monday, $4 on Tuesday, and the previous day's amount gets multiplied by 2 each day. Which of the following would represent how much money Gina would receive on Thursday?
Answer:
Gina would receive $16 equivalent to 2^4 on Thursday from her grandfather
Step-by-step explanation:
A. 2^5
B. 2^4
C. 2^3
D. 2^2
Gina gets:
Monday =$2 = $2^1
Tuesday =$4 = $2^2
Previous day's amount get multiplied by 2
Wednesday = Tuesday's amount × 2
= $4 × 2
= $8
= $2^3
Thursday = Wednesday's amount × 2
= $8 × 2
= $16
= $2^4
Gina would receive $16 equivalent to 2^4 on Thursday from her grandfather
Answer:
the answer is 2^4

Step-by-step explanation:
we have to find a number that gives a remainder of 1 when divided by both 2, 3 and 5.
The easiest way to do this is to list the factors of 5, add 1 to it, and test them until we find the one with a remainder of 1 by all three divisors. This is done as follows:
1) factor: 5 (+1) = 6
6 ÷ 2 = 3 remainder 0
6 ÷ 3 = 2 remainder 0
since there is a remainder of 0, when divided by 3, 6 is wrong
2) factor; 10 (+1) = 11
11 ÷ 3 = 3 remainder 2 ( 11 is not the correct answer
3) factor : 15 (+1) = 16
16 ÷ 2 = 8 remainder 0 ( 16 is not the correct answer
4) factor : 20(+1) = 21
21 ÷ 3 = 7 remainder 0 ( 21 is wrong)
5) factor : 25(+1) = 26
26 ÷ 2 = 13 remainder 0 ( 26 is wrong)
6) factor : 30(+1) = 31
31 ÷ 2 = 15 Remainder 1
31 ÷ 3 = 10 Remainder 1
31 ÷ 5 = 6 Remainder 1
since all three divisors give a remainder of 1, the correct answer is 31
Therefore you have 31 pwnnies

Answer:
7/9
Step-by-step explanation:
Since a negative times a negative is positive, -(-1) becomes + 1 so the expression becomes -2/9 + 1. Using the commutative property of addition (a + b = b + a), we can rewrite this as 1 - 2/9. 1 = 9/9 so the expression becomes 9/9 - 2/9 = 7/9.
Find the area of the region enclosed by the graph of $x^2 + y^2 = 2x - 6y + 6$
Answer:
16π ≈ 50.27 square units
Step-by-step explanation:
The equation is that of a circle of radius 4. The area of a circle is given by ...
A = πr²
A = π(4²) = 16π ≈ 50.27 . . . . square units
_____
The equation can be put into the standard form for a circle to find its radius.
(x^2 -2x) +(y^2 +6y) = 6 . . . . collect variable terms on the left
(x^2 -2x +1) +(y^2 +6y +9) = 6 + 1 + 9 = 16 . . . . . complete the squares
(x -1)^2 +(y +3)^2 = 4^2 . . . . . the radius is 4
Compare to the form ...
(x -h)^2 +(y -k)^2 = r^2 . . . . circle of radius r centered at (h, k)
