A veterinarian treated 7 dogs, 13 cats, 4 horses, and 3 ferrets. What percentage of his patients were small animals?

1 answer:

6 0

According to your definition, horses are the only creatures labeled as "not small". To determine the percentage, divide the number of small animals by the total number.

So, 7 dogs + 13 cats + 3 ferrets = 23 small animals

7 dogs + 13 cats + 3 ferrets + 4 horses = 27 total animals.

Thus,

$\frac{23}{27}*100$

The multiplication by 100 is necessary because dividing results in a decimal, and a percentage is a fraction of 100.

This leads us to the calculation which yields

85.18%

What is the empirical formula of an oxide of chromium that is 48 percent oxygen by mass?

Svet_ta [12734]

Answer:

CrO₃.

Step-by-step explanation:

First, we will find the chromium percentage in the oxide by using the following process:

Oxygen (O) = 48%

Chromium (Cr) =?

The oxide consists solely of chromium and oxygen, and its chromium percentage is calculated as:

Cr = 100 – percentage of oxygen

Cr = 100 – 48

Cr = 52%

Next, we will determine the empirical formula for the oxide:

Chromium (Cr) = 52%

Oxygen (O) = 48%

Now, we divide by their molar mass:

Cr = 52/52 = 1

O = 48/16 = 3

Now, divide by the lowest value:

Cr = 1/1 = 1

O = 3/1 = 3

Thus, the empirical formula for the oxide is CrO₃.

MNOP is a trapezoid with median QR find X

AnnZ [12381]

Answer:[[TAG_3],[TAG_4],[TAG_5]]B

Step-by-step explanation:

Given that QR is the median and measures 12, while NO measures 8, the difference is 12-8=4.

Thus, I will state that 2x+6 equals 16.

Setting the equation as 2x+6=16

2x=10

x=5

USING STRUCTURE An athletic facility is building an indoor track. The track is composed of a rectangle and two semicircles, as s

AnnZ [12381]

Answer:

Step-by-step explanation:

Refer to the attached digram.

The track's perimeter consists of the rectangle's perimeter plus the perimeters of the two semicircles.

The perimeter of a rectangle can be expressed as 2(x+r) where:

x is the length

2r represents the rectangle's width, equivalent to the semicircle's diameter.

The perimeter of one semicircle is calculated as 2πr/2, simplifying to πr.

Thus, the total perimeter contributed by the two semicircles is 2πr.

Therefore, the full track perimeter is expressed as 2(x+2r) + 2πr

where r indicates the semicircle's radius.

Expanding this gives us

Perimeter of the track = 2x + 4r + 2πr

which can also be represented as Perimeter of the track = 2(x + 2r + πr)

b) Given P = 2(x + 2r + πr), we need to rearrange the equation to isolate x.

P = 2x + 4r + 2πr

By subtracting 4r and 2πr from both sides, we get P - 4r - 2πr = 2x

Next, we divide each side by 2.

(P - 4r - 2πr) / 2 = 2x

Thus, x = (P - 4r - 2πr) / 2

c) Given

P = 600ft

r = 50ft

x = (600 - 4(50) - 2π(50)) / 2

x = (600 - 200 - 100(3.14)) / 2

x = 400 - 314 / 2

x = 86 / 2

x = 43ft

Therefore, rounding to the nearest foot, the value of x is 43ft
