Carlo puts tins into small boxes and into large boxes. He puts 6 tins into each small box. He puts 20 tins into each large box.

meriva

Answer: Carlo is incorrect

Step-by-step explanation:

3000/(2+3) = 600 (each ratio)

2:3 = 2(600):3(600) = 1200:1800

1200/6 = 200 small boxes

1800/20 = 90 large boxes

290 boxes altogether (large and small)

(large boxes/boxes altogether)x100

(90/290)x100 = 31%

31%>30%

Therefore Carlo is incorrect

Linn plans to wallpaper the 4 walls in her bedroom. The measurements are 9’ by 11’ by 8’. How many single rolls of wallpaper sho

Ann [662]

Answer: There are 4 rolls she should buy.

Step-by-step explanation:

Since we have given that

Length of wall = 9 feet

Width of wall = 11 feet

Height of wall = 8 feet

As we know the formula for "Area of four walls ":

$Area=2(l+b)h\\\\Area=2(9+11)\times 8\\\\Area=2\times 20\times 8\\\\Area=320\ ft^2$

Area of each single roll covers = 72 square feet

So, Number of single rolls of wallpaper is given by

$\frac{\text{ Area of 4 walls}}{\text{ Area of single roll}}\\\\=\frac{320}{72}\\\\=4.44\\\\=4$

Hence, there are 4 rolls she should buy.

What is the value of x

goblinko [34]

Answer:

52/3

Step-by-step explanation:

Use basic Thales therom,

$\frac{3x}{4x}=\frac{3x+7}{5x-8}\\\\\frac{3}{4}=\frac{3x+7}{5x-8}\\$

Cross multiply,

3*(5x-8)=4*(3x+7)

3*5x - 3*8 = 4*3x + 4*7

15x - 24 = 12x +28

Add 24 to both sides

15x = 12x + 28 + 24

15x = 12x + 52

Subtract 12x from both sides

15x-12x =52

3x = 52

Divide both sides by 3

x = 52/3
