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.

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.

Answer:

The last one

Step-by-step explanation:

68/5 - 22/5 = 46/5 = 9 1/5

Answer:

Option d

Explanation:

[tex]\frac{68}{5} - \frac{22}{5} = \frac{46}{5}[/tex]

46/5 in mixed fraction is [tex]9\frac{1}{5}[/tex]

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.

Answer:

Answer:

$6.36 would be your answer￣へ￣

Answer: 0.56 round to the nearest tenths which is 6. So, it’s $6

Step-by-step explanation:

Step-by-step explanation:

connect the points p and s

and comnect the points q and t

take triangle PQS and triangle TSQ

SQ similar to SQ

PQ similar to QS

QS similar to ST

therefore triangle PQS similar to triangle TSQ

Therefore , PQ/ QS = ST/ QS

PQ=ST

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

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

42 divied by 3kg the after you get that answer then multiply that by 4kg

Step-by-step explanation:

3 kg of rump steak = £ 42

So, 1 kg of rump steak = £ 42/3 = £ 14

So, 4 kg of rump steak = £ 14 × 4 = £ 56

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

Answer:

Less

Step-by-step explanation:

Think of it like this:

Four times of 0.36
