In the attachment count the shaded, and the total amount make it to a fraction, and then simplify to make it to a percentage
Alisiya [41]

Answer:

30/75  2/5

Step-by-step explanation:

there are 30 shaded squares, and a total of 75 squares. Therefore the fraction is 30/75.   This can be simplified to 2/5 if both sides are divided by fifteen.

To make a percentage, simply divide 2 by 5 which equals 0.4 = 40%

Find the total surface area of the 3D figure:<br> ft2<br> 9 ft<br> 8 ft<br> 6 ft<br> 8 ft<br> 8 ft
N76 [4]

Answer:

a = 132 ft^2

Step-by-step explanation:

Area of triangle

a = (1/2)bh

---------------------------

Base

a = (1/2)(8)(6)

a = 24 ft^2

----------------------

Each side

a= (1/2)*(8)(9)

a = 36

All three sides

a = 36 * 3

a = 108 ft^2

-----------------------

Total area

a = 24 + 108

a = 132 ft^2

To get to work, you drive for 20 minutes at 30 mph, and walk 10 more minutes at 3 mph. What was your average speed?
fiasKO [112]
<span>Note D = r(t)
20min = 1/3 hr and 10min = 1/6 hr

(1/3hr)30mph + (1/6hr)3mph = 10.5 mi, the total distance traveled.

total distance / total time = average speed = 10.5/(1/3 + 1/6) = 10.5/(2/6 + 1/6)
10.5mi/.5hr = 21mph

Hope This Helps </span>

jasmijn is a pet groomer. She charges n dollars to clip a dog's nails, w dollars to wash the dog, and h dollars to cut a dog's h
notka56 [123]

Given, the charges to clip a dog's nail = $n

The charges to wash the dog = $w

The charges to cut a dog's hair = $h

The total charges Jasmin take for 1 dog = $n+$w+$h = $(n+w+h)

For 4 dogs we can get total charges by multiplying the total charge for 1 dog with 4.

So, the total charges for 4 dogs = $(n+w+h) × 4 = $ 4(n+w+h) = $(4n+4w+4h)

So we have got the required answer.

The total charges for 4 dogs = $ 4(n+w+h) = $(4n+4w+4h)
