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.
Multiply: (5.8 x 10^-6) x (2 x 10^4).
Answer:
[tex]1.16*10^{-1}[/tex]
Step-by-step explanation:
[tex](5.8*10^{-6}) *(2*10^{4})\\=11.6*10^{-2}\\=1.16*10^{-1}[/tex]
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.

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.
Will give brainliest if correct.
Answer:
y = -5x - 10
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y-intercept
Now, in your case:
5x + y = -10
Move 5x (don't forget to change the signs!):
y = -5x - 10
Hope this helps!

30 workers can complete a work in 40 days in how many days would 20 men complete the construction
Answer:
27
Step-by-step explanation:
(30 workers/40 days) = (20 workers/x days) cross multiply
30*x=40*20 divide by 30 both sides
x= 800/30
x≈26.67
So they will need 27 days
James paid 13.20 for 12 mangoes. For every 5 mangoes that he bought he got one mango free. Mary wants to by 4 mangoes from the same shop. She only has $5.10. How much more money does she need
Answer:
Mary needs $0.18 more
Step-by-step explanation:
12 mangoes = $13.20
For every 5 mangoes that he bought he got one mango free
This means he bought 10 mangoes (5 mangoes + 1 free mango the first time and 5 mangoes + 1 free mango the second time)
If James paid $13.20 for 10 mangoes, then
Each mango cost = $13.20 / 10
= $1.32
Each mango cost $1.32
Mary wants to by 4 mangoes from the same shop.
Total cost of 4 mangoes = $1.32 × 4
= $5.28
She only has $5.10.
How much more money does she need
Amount needed more = Total amount required - total amount available
= $5.28 - $5.10
= $0.18
Mary needs $0.18 more
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

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
