Pearl uses 9.8 pints of blue paint and white paint to paint her bedroom walls. 2 5 of this amount is blue paint, and the rest is
Ratling [72]

Answer:

She use <u>5.88 pints</u> of white paint.

Step-by-step explanation:

Given:

Pearl uses 9.8 pints of blue paint and white paint to paint her bedroom walls. \frac{2}{5} of this amount is blue paint, and the rest is white paint.

Now, to find the pints of white paint she use.

Pearl uses total pint of paint = 9.8 pints.

The amount of blue paint

= \frac{2}{5}\ of\ 9.8\ pints.

= \frac{2}{5} \times 9.8

= \frac{19.6}{5}

= 3.92\ pints.

Thus, the amount of blue paint = 3.92 pints.

Now, to get the white paint we subtract the amount of blue paint from  the total pint of paint:

9.8-3.92\\\\=5.88\ pints.

Therefore, she use 5.88 pints of white paint.

A square of area 36 cm2 is cut out to make two rectangles , A and B The area of area A to area B is 2 : 1 work out the dimension
KIM [24]

Answer:

Dimensions of:

Rectangle A are 6 cm by 4 cm.

Rectangles B are 6 cm by 2 cm.

Step-by-step explanation:

It is given that:

The area of square is 36 cm^2.

Hence, the side of the square is given as:

Area=(side)^2\\\\36=(side)^2\\\\side=6

Hence, the side of square is 6 cm.

Now, as the area of two rectangles A and B are in the ratio:

2:1

This means that, the area of rectangle A is 24 cm^2.

and area of rectangle B is 12 cm^2.

( Since, 36/(2+1)=36/3=12

Area of rectangle A=2×12=24 cm^2.

Area of rectangle B=1×12=12 cm^2. )

Hence, the dimensions of A are:

6 cm by 4 cm.

and the dimensions of rectangle B are:

6 cm by 2 cm.

Find the difference!!!!!!!!!!!!!!!!!!11
pav-90 [236]

Answer:

-4

Step-by-step explanation:

-10 - (-6)

Remove the brackets:

-10 - - 6

Remember that all negative and negative values are always positive because they are the same; if they are different, for instance, a positive value and a negative value, then that value will be a negative value.

Continue solving:

-10 - - 6

- and - are positive values

- 10 + 6

= - 4

Therefore the answer is 4
