2i√5

Explanation:
When using square root on a negative, simply take out the negative and use an i. This way, the equation is i√20.
Simplify the 20 by taking out 4 and 5.

i√4*5
Since the square root of 4 is 2, you can take out the 4 and replace it with a 2 on the outside.

Fiona has a job at a garage.

Stolb23 [73]

Yes.

8 + 1 + 1 = 10, so there are 10 parts to the ratio.
3.5 litres divided by 10 would mean that each part of the ratio is worth 0.35 litres.
The colour is worth 8 parts of the ratio. 0.35 litres multiplied by 8 would give 2.8 litres, meaning 2.8 litres of colour are required.
Fiona has 2.9 litres of colour, which is more than enough to make 3.5 litres of paint mix.

José and Maris work for different car dealerships. José earns a monthly salary of $3,500 plus a 8% commission on sales. Maris ea

kaheart [24]

Answer: When sales are greater than 2000 then José's monthly earnings sre more than those of Maris.

Step-by-step explanation:

Let x= Total sales

For José, monthly salary = $3,500

Commission percentage = 8% =0.08

Monthly earnings= Monthly salary + (Commission percentage) x (Total sales)

Monthly earnings= 3500 +0.08 x

For Maris, monthly salary = $3,900

Commission percentage = 6%

Monthly earnings= 3900 +0.06 x

When José's monthly earnings > Maris's monthly earnings

then, 3500 +0.08 x > 3900 +0.06 x

Subtract 3500 from both sides, we get

0.08 x > 400+0.06x

Subtract 0.06x from both sides, we get

0.02x>400

Divide both sides b 0.02

x> 20000

When sales are greater than 2000 then José's monthly earnings sre more than those of Maris.

PLEASE ANSWER THIS QUESTION RIGHT Name the x-intercept(s)?<br> A:0 and 4,B:2,C:4,D:0.

harina [27]

Answer:

A. 0 and 4

Step-by-step explanation:

The x-intercepts are simply the values of x when y = 0. In other words it is the points where the line curve intercepts or cuts across the x-axis.

Form the graph given, we can see that at x = 0 and x = 4, the value of y = 0. Simply put, the curve cuts the x-axis at x = 0 and x = 4.

x-intercepts are 0 and 4.
