Answer:x

=

5

toppings

Step-by-step explanation:Total cost of cheese pizza:

$

10.75

Any additional topping adds:

+

$

1.25

So a cheese pizza with

1

additional topping is:

$

10.75

+

$

1.25

=

$

12.00

A cheese pizza with

2

additional toppings is:

$

10.75

+

$

1.25

+

$

1.25

=

$

10.75

+

2

$

1.25

=

13.25

A cheese pizza with

3

additional toppings is:

$

10.75

+

$

1.25

+

$

1.25

+

$

1.25

$

10.75

+

3

×

$

1.25

=

$

14.50

If you pay attention to the pattern you can see that, for any number of toppings, say

x

toppings, the price is going to be:

$

10.25

+

x

×

$

1.25

We are told the final cost is

$

17.00

. That is

$

10.25

$

1.25

=

$

17.00

Subtract

$

10.25

from both sides

$

10.25

$

1.25

=

6.25

Divide both sides by

ASAP. Can someone help me find the percentage of these please, I can't figure it out. (Pic below)

atroni [7]

Answer:

Interphase: 55.56%

Prophase: 27.78%

Metaphase: 8.33%

Anaphase: 5.56%

Telophase: 2.78%

Step-by-step explanation:

All you need to do is follow the instructions. To get the percentage, all you need to do is divide the part by the whole then multiply it by 100%.

$\dfrac{Part}{Whole}\times 100\%$

Now let's take your problem:

Number of cells in interphase:

20 this is the part and the whole would be the total cells, which is 36. Now we insert that into our equation:

$\dfrac{20}{36}\times 100\%=0.5556\times100\%=55.56\%$

So now we apply the same to the rest:

Prophase:

$\dfrac{10}{36}\times 100\%=0.2778\times100\%=27.78\%$

Metaphase:

$\dfrac{3}{36}\times 100\%=0.0833\times100\%=8.33\%$

Anaphase:

$\dfrac{2}{36}\times 100\%=0.0556\times100\%=5.56\%$

Telophase:

$\dfrac{1}{36}\times 100\%=0.0278\times100\%=2.78\%$

(-19+7i)-(29+32i)=<br><br> in the form (a+bi)

olga_2 [115]

ANSWER

$-48-25i$

EXPLANATION

We want to simplify the expression,

$(-19+7i) - (29+32i)$

Let us expand the bracket to obtain,

$-19+7i-29-32i$

We now group the complex number parts and real number parts.

$-19 -29+7i-32i$

We simplify further to obtain,

$- 48-25i$

This is in the form,

$a+bi$

where

$a=-48$

and

$b=-25$
