Answer:

Her model is 37 times as tall as Ben's.

Step-by-step explanation:

70 11/12 ÷ 5 3/4

851/12 ÷ 23/4

851/12 x 4/23

37/1 x 1/1 = 37 times as tall

A large community college has professors and lecturers. The total number of faculty is 228. The school reported that they have 5

Ivan

The large community college has 76 professors and 212 lecturers

<u>Solution:</u>

Given that,

Total number of faculty = 228

Let, the number of professors be p, then the number of lecturers will be 228 – p

They have 5 professors for every 14 lecturers.

Then, ratio of professors to lecturers is 5 : 14

Expressing the ratio as fractions, we get,

$\rightarrow \frac{\text {number of professors}}{\text {number of lecturers}}=\frac{5}{14}$

Plug in the values of number of professors and lecturers

$\rightarrow \frac{p}{288-p}=\frac{5}{14}$

$\begin{array}{l}{\rightarrow 14 \times p=(288-p) \times 5} \\\\ {\rightarrow 14 p=1440-5 p} \\\\ {\rightarrow 14 p+5 p=1440} \\\\ {\rightarrow 19 p=1440} \\\\ {\rightarrow p=75.789 \approx 76}\end{array}$

So, community has 76 professors, then, it will have 288 – 76 = 212 lecturers.

Is this right? i’m not sure

My only issue is that it says numbers between. It does not say including. Therefore, I think you want to use > and < instead of the ones with equals signs attached.

Answer:

The formula for area of a circle is : A = PI x r^2

A) find the are of the two circles, subtract the two to find the area of the side walk:

Outside circle: A = PI x 10^2

Area = 100PI

Inner circle: A = PI x 8^2

Area = 64PI

Area of sidewalk:

100PI - 64 PI = 36PI

B) replace PI with 3.14:

Area = 36 x 3.14 = 113.04 square meters.

Step-by-step explanation:

Hope this helped.
