cluponka [151]

Answer:

<u>There are 35 Men, 12 Children, and 18 Women</u>

Step-by-step explanation:

Men(M), Women(W) and Children(C)

We learn that:

M = 35

W = 1.5C , and

M+W+C = 65

----

M+W+C = 65

M+1.5C+C = 65

35+1.5C+C = 65

2.5C = 30

C = 12

If C=12 and W=1.5C, then W=18

----

<u>There are 35 Men, 12 Children, and 18 Women</u>

(35+12+18) = 65 participants

Joe Popoff, a collection agent, collected 90% of a debt of $5,600.00 that had been overdue 90 days. This collection rate was 5%
sergey [27]
<span>You are given the debt collected by Joe Popoff with a 90% of a debt of $5,600.00 that had been overdue 90 days. This collection rate was 5% more than the average collection rate for that agent. The agent charged 25% commission. You are asked to find the net proceeds. 

Amount collected
= $5,600 * 0.90
= $5,040

Commision
= $5,040 * 0.25
= $1,260

Net Proceeds
= $5,040 - $1,260
= $3,780 </span>

Find the lateral area of the square pyramid shown to the nearest whole number.
Xelga [282]

Answer:

4,300

Step-by-step explanation:

Lateral area of a squared Pyramid is given as ½ × Perimeter of base (P) × slant height of pyramid

Thus, we are given,

Side base length (s) = 43 yd

height (h) = 25 yd

Let's find the perimeter

Permimeter = 4(s) = 4(43) = 172 yd

Calculate the slant height using Pythagorean theorem.

Thus, l² = s²+h²

l² = 43²+25² = 1,849+625

l² = 2,474

l = √2,474

l ≈ 50 yd

=>Lateral area = ½ × 172 × 50

= 172 × 25

= 4,300 yd
