Answer:

standrad = 220 download

Step-by-step explanation:

x(number of standtrad download) y(number of high quality downloads)

y=3x

4.2y+2.7x=3366

4.2(3x)+2.7x=3366

12.6x+2.7x=3366

15.3x=3366

x=3366/15.3

x=220

y=3(220)=660

Find the value of b. B² = 256

Jlenok [28]

$B^2=256$

$\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}$

$B=\sqrt{256},\:B=-\sqrt{256}$

$\sqrt{256}$

$\mathrm{Factor\:the\:number:\:}\:256=16^2$

$=\sqrt{16^2}$

$=16$

$-\sqrt{256} =-16$

$B=16,\:B=-16$

Quesuon 10 of 10

Bad White [126]

Answer:

(p, q) is (2, 5)

Step-by-step explanation:

Given the expression

x^2 + 3x - 10

Factorize;

x^2 + 5x - 2x - 10

x(x+5) - 2(x+5)

(x-2)(x+5)

Comparing with (x + p)(x + 9).

x+2 = x+ p

x-x+2 = p

2 = p

p = 2

Similarly;

x+5 = x+q

x-x+5 = q

5 = q

q= 5

Hence (p, q) is (2, 5)

a square of area is 36 cm squared is cut to make two triangles, A and B. The ratio of area A to area B is 2:1. Work out the dime

weeeeeb [17]

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 cm².

and area of rectangle B is 12 cm²

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

Area of rectangle A=2×12=24 cm²

Area of rectangle B=1×12=12 cm². )

Hence, the dimensions of A are:

6 cm by 4 cm.

and the dimensions of rectangle B are:

6 cm by 2 cm.
