Answer: the lengths are 20 feet, 23 feet and 37 feet
Step-by-step explanation:
Let x represent the length of the shorter side of the triangular deck.
The second side of a triangular deck is 3 feet longer than the shortest side. This means that the length of the second side is (x + 3) feet.
The third side is 3 feet shorter than twice the length of the shortest side. This means that the length of the third of the triangle is (2x - 3) feet.
If the perimeter of the deck is 80 feet, it means that
x + x + 3 + 2x - 3 = 80
4x = 80
x = 80/4
x = 20
The length of the second side is
20 + 3 = 23 feet
The length of the third side is
20 × 2 - 3 = 40 - 3 = 37 feet
Answer:
Approximately 71 guests
Step-by-step explanation:
Ms. Wapel is serving ice cream at her party. She has purchased 23 3/4 pints of ice cream. Expressing 23 3/4 pints of ice cream as improper fraction, it will become 95/4
She will serve 1/3 of a pint to each guest. To determine the number of guests that can be served ice cream, we will divide the total pints of ice cream that she purchased by the number of pints that she wants to serve each guest. It becomes
95/4 ÷1/3 = 95/4 × 3/1 = 71.25
She can serve approximately 71 guests
Answer:
07.50086956521739% (round it)
Step-by-step explanation:
Find what percent 43.13 (Number A) is of 575 (Number B). To do this you divide Number A by Number B.
43.13 / 575 = 0.0750086956521739
Move the decimal point two places to the right.
007.50086956521739
Get rid of the zeros.
7.50086956521739
Step-by-step explanation:
Total students = 1575
No of females = 870
No of males = 1575 - 870 = 705
Ratio of females to males
870 : 705
In simplest form
58 : 47
I'm taking radius to be half of the side length.Then one side is 26 cm and the area of a square is the length of a side squared.A=26^2=676So,C) 676
