Answer:
The question is not clearly stated, but I can correctly infer that you wanted to ask the question below:
Out of 150 members, 120 took part, what is the percentage of the total that took part:
Answer:
80%
Step-by-step explanation:
The question is asking us to find what percentage of 150 is 120
Let the percentage of 150 that is 120 be x
x % of 150 = 120
x/100 × 150 = 120
0.01x × 150 = 120
0.01x = 120 ÷ 150 = 0.8
x = 0.8 ÷ 0.01 = 80
∴ 120 = 80% of 150
6 + 6 + 4 + 4 = 20 = perimeter
Squares are cut from the corner, so we are left with only one variable.
The area of a rectangle, the bottom of the pan, is base*height.
Let's call the sides of the removed squares "x"
so 192 = (20-x)(24-x) foil to expand the binomials
192 = 480 - 44x - x squared Take 192 away from both sides
0 = 288 - 44x - x squared
0 = (36 - x)(8-x)
x = 36 and x = 8
Because 36 > 24 and 36 > 20, in this case, the squares cannot be
36cm x 36cm and therefore must be 8cm x 8cm.
Check:
(20-8)(24-8) = 192
Answer:
$2.50
Step-by-step explanation:
Shelley buys one pack of gum for $1
Price of gum: $1
Total amount of money spent: $1.00
Shelley buys another pack of gum for $0.50 more
1 + 0.50 = 1.5
Price of gum: $1.50
Total amount of money spent: $2.50
