Without multiplying, is 4 × 0.36 less
than or greater than 4? Explain its for my little sis oof
Answer:
Less
Step-by-step explanation:
Think of it like this:
Four times of 0.36
0.36 + 0.36 + 0.36 + 0.36 = 1.44
So 4 × 0.36 is less than 4
Hope I helped your little sista :)
An element's identity is determined by the number of
Answer:
number of protons
Step-by-step explanation:
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.

Twelve large bottles of water cost $9.How many bottles can you buy for $3?
Answer: 4 large bottles of water for $3.
Step-by-step explanation: To find how many large water bottles you can buy with $3, you’ll have to divide 12 by 3 which equals to 4. You can check your answer by multiplying 4 x 3 which equals to 12, which is the original amount of large water bottles you can buy for $9.
Emily is preparing cookies for her friends she is at the market where she sees a 14 ounce bag of chocolate chips for 3.50 the market also sells a 24 ounce bag for 5.28 which size bag is better to buy
Answer:
Bag 2
Step-by-step explanation:
Given
Bag 1:
[tex]14\ ounce = 3.50[/tex]
Bag 2:
[tex]24\ ounce = 5.28[/tex]
Required
Which is a better buy
To get which buy is better, we first get the unit price of each bag.
[tex]Unit\ Price = Amount/Size[/tex]
For bag 1:
[tex]Unit\ Price = 3.50/14[/tex]
[tex]Unit\ Price = 0.25[/tex]
For bag 2:
[tex]Unit\ Price = 5.28/24[/tex]
[tex]Unit\ Price = 0.22[/tex]
The best buy is the one with smaller unit price
Hence, bag 2 is better to buy
Which linear equations have an infinite number of solutions? Check all that apply.
(x – 3\7) = 2\3 (3\2x – 9\14 )
8(x + 2) = 5x – 14
12.3x – 18 = 3(–6 + 4.1x)
1\2(6x + 10) = 7(3\7x – 2)
4.2x – 3.5 = 2.1 (5x + 8)
Answer:
a) (x – 3\7) = 2\3 (3\2x – 9\14 )
c) 12.3x – 18 = 3(–6 + 4.1x)
Step-by-step explanation:
A linear equation can be said to have an infinite number of solutions when the number of the right hand side is the same at the number on the left hand side of the equation.
For example:
2 = 2 or x = x or 0 = 0
Solving the question above:
Which linear equations have an infinite number of solutions? Check all that apply.
a) (x – 3\7) = 2\3 (3\2x – 9\14 )
x - 3/7 = 6x/6 - 18/42
x - 3/7 = x - 3/7
Collect like terms
x - x = -3/7 + 3/7
0 = 0
The linear equation in option a has an infinite number of solutions
b) 8(x + 2) = 5x – 14
8x + 16 = 5x - 14
Collect like terms
8x - 5x = -14 - 16
3x = -30
x = -30/3
x = -10.
The linear equation in Option b has a true solution.
c) 12.3x – 18 = 3(–6 + 4.1x)
12.3x - 18 = -18 + 12.3x
Collect like terms
12.3x - 12.3x = -18 + 18
0 = 0
The linear equation in Option c has infinite number of solutions
d) 1\2(6x + 10) = 7(3\7x – 2)
6x/2 + 5 = 21/7x - 14
3x + 5 = 3x - 14
Collect like terms
3x - 3x = -14 - 5
0 = -19
The linear equation Option d has no solution
e) 4.2x – 3.5 = 2.1 (5x + 8)
4.2x - 3.5 = 10.5x + 16.8
Collect like terms
4.2x - 10.5x = 16.8 + 3.5
-6.3x = 20.3
x = -20.3/6.3
x = -3.22
Hence, the linear equation in Option e has a true solution
Therefore, the linear equations have an infinite number of solutions are:
a) (x – 3\7) = 2\3 (3\2x – 9\14 )
c) 12.3x – 18 = 3(–6 + 4.1x)
Answer(x – 3\7) = 2\3 (3\2x – 9\14 ) and (12.3x – 18 = 3(–6 + 4.1x)

What is the equation of a line passing through the point (-4, 8) that is parallel to the line y = 2x + 6
Answer:
y = 2x + 16
Step-by-step explanation:
slope is parallel and equal to y = 2x + 6
y intercept = 16
Answer:
b - y=2x+16
Step-by-step explanation:
y=y1+m(x+x1)
(-4,8)
y=8+2(x-4)
y=8+2x-8
add 8 on both sides
y=2x+16

The three-digit number "ab5" is divisible by 3. How many different three-digit numbers can "ab5" represent?
Answer:
30
Step-by-step explanation:
I can't prove this, but I can tell you the answer.
30.
a = 100 s digit
b = 10 s digit
5 is always the units digit.
I'm pretty sure that 30 is the correct answer.
What an interesting question. If I find out how it is done, I'll post it in the comments.
I can say this much.
a + b + 5 must be divisible by 3.
a = 1 b = 9 + 5
a = 1 b = 6 + 5
a = 1 b = 3 + 5
a = 1 b = 0 + 5
===============
Three more are obtained by interchanging the 100s and 10s digit except for b = 0
a = 9 b=1 + 5
a = 6 b =1 + 5
a = 3 b= 1 + 5
==================
a = 2 b = 2 + 5
a = 2 b = 5 + 5
a = 2 b = 8 + 5
only 2 more are obtained by interchanging the 10s and 100s digit
=============
a = 3 b = 4 +5
a = 3 b = 7 +5
You can't go any further. You get 2 more by interchanging the b and a digits.
=============
I hope you see what I've done here. I don't think this is an exact proof, but it is an exhaustive search.
Fifteen more than the square of a number is eight times the number.
Answer: n = 3 or 5
n^2+15=8n
Or,
n2 - 8n + 15 = 0
(n - 3)(n - 5) = 0
So n is 3 or 5.
un terreno rectangular tiene 12 m. De frente y 40 m de fondo .
¿ cuál es el costo del terreno si el metro cuadrado cuesta $2100?
Answer:
El costo de las dimensiones dadas es $ 1092000
Step-by-step explanation:
Dada
Longitud = 13m
Profundidad = 40m
Costo de 1m² = $ 2100
Required
Determine el costo del terreno Primero, necesitamos determinar el área del terreno.
Primero, necesitamos determinar el área del terreno.
Área = Longitud * Profundidad
Valores sustitutos de Longitud y Profundidad
Área = 13m * 40m
Área = 520m²
A continuación, calculamos el costo del área calculada
Si 1m² cuesta $ 2100
Entonces
520m² cuesta $ 2100 * 520
Costo = $ 1092000
Por lo tanto, el costo de las dimensiones dadas es $1092000

8x-4y= -56 put in
slope-intercept form
Answer: x=2x +14
Step-by-step explanation:
1) subtract 8x from both sides: -4x= -8x -56
2) divide both sides by -4: x=2x +14
Determine the solution to the equation. 8+4x=2x+8+2x
Answer: x= all real numbers.
Step-by-step explanation: Simplify the equation first. 8+4x=2x+8+2x. Add the variables on the right side. 4x+8=4x+8. Because the two sides are exactly equal, x can be all real numbers.
Answer:
8=8
Step-by-step explanation:
8+4x=2x+8+2x
combine like terms
8+4x=4x+8
subtract 4 from both sides
8=8

The cost $y$ (in dollars) to rent a kayak is proportional to the number $x$ of hours that you rent the kayak. It costs $27 to rent the kayak for 5 hours
Note: Consider we need to find the constant of proportionality.
Given:
The cost y (in dollars) to rent a kayak is proportional to the number x of hours that you rent the kayak.
It costs $27 to rent the kayak for 5 hours.
To find:
The constant of proportionality.
Solution:
The cost y (in dollars) to rent a kayak is proportional to the number x of hours that you rent the kayak.
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is constant of proportionality.
It costs $27 to rent the kayak for 5 hours. So, put x=5 and y=27 in the above equation.
[tex]27=k(5)[/tex]
Divide both sides by 5.
[tex]\dfrac{27}{5}=k[/tex]
Therefore, the constant of proportionality is [tex]\dfrac{27}{5}[/tex].
