Jesse estimates the weight of her cat to be 10 pounds. The actual weight of the cat is 13.75.Find the percent of error.
horrorfan [7]

Answer:

The percent error is 27.27%

Step-by-step explanation:

I did this by using the formula actual-estimated value/actual value

In this case it would be 3.75/13.75 and I got .2727 and then had to multiply by 100 (to find percent not decimal form) and got 27.27%

an administrator is asked to file papers in a box which has the following dimensions:height 15cm, width 300mm and depth 0.2m. ca
nalin [4]

Answer:

900cm^3

Step-by-step explanation:

1 cm= 10 mm

x=300mm (criss cross)

1cm*300mm/10mm= 10mm*x/10mm

30cm=x

30cm=300mm

1m=100cm

0.2m=x

1m*x/1m=0.2m*100cm/1m

x=0.2*100cm

x=20cm

0.2m=20cm

l=15cm

w=30cm

h=20cm

v=l*w*h

v=15cm*30cm*20cm

v=450cm^2*20cm

v=900cm^3

7x+3x+3=4x+6 what is x
vovikov84 [41]

Answer:

x = 1/2

Step-by-step explanation:

<em>Simplify the sides of the equation...</em>

<em>10x + 3 = 4x + 6</em>

<em>Subtract 3 from both sides...</em>

<em>10x = 4x + 3</em>

<em>Subtract 4x from both sides...</em>

<em>6x = 3</em>

<em>Divide by 6</em>

<em>x = 1/2</em>

<em />

<em>Thank me later :)</em>

<em>(or just give brainliest)</em>
