A softball team hopes to win at least 3 games
for every 2 lost during the season. If there are
45 games scheduled, how many games can the
team lose and still achieve its goal?
Answer:
y=27
x=18
Step-by-step explanation:
x-games won
y-games lost
x+y=45
3x=2y
x=45-y
3(45-y)=2y
135-3y=2y
135=3y+2y
135=5y
y=27
x=(45-27)
x=18

What is the measure of DA? (in a parallelogram)
Answer:
DA = 24
Step-by-step explanation:
the opposite sides of a parallelogram are congruent , then
CD = BA , that is
5x - 18 = 2x + 12 ( subtract 2x from both sides )
3x - 18 = 12 ( add 18 to both sides )
3x = 30 ( divide both sides by 3 )
x = 10
Then
CB = 3x - 6 = 3(10) - 6 = 30 - 6 = 24
so
DA = CB = 24

Mr. Tan's rectangular swimming pool has an area of (81x2 - 144y2) square feet. What are the dimensions of his pool?
Answer:
The pool dimensions are thus (9x - 12y)(9x + 12y)
Step-by-step explanation:
(81x^2 - 144y^2) is the difference of two squares. Note that you must indicate exponentiation with " ^ ."
Factoring the difference of two squares: a^2 - b^2 = (a - b)(a + b)
Thus, (81x^2 - 144y^2) =
The pool dimensions are thus (9x - 12y)(9x + 12y)
Area of rectangle is Length times of Breadth. The pool dimensions are (9x - 12y) and (9x + 12y) when area of rectangular swimming pool is (81x2 - 144y2)
area of Mr. Tan's rectangular swimming pool is (81x^2 - 144y^2), we need to find the area of rectangle.
What is area of rectangle?Area of rectangle= Length*Breadth
The given area of Mr. Tan's rectangular swimming pool is (81x^2 - 144y^2),
(81x^2 - 144y^2)=Length * Breadth
We know that (a+b)(a-b)=a^2-b^2
So,
The factors of (9x^2-12y^2) is (9x+12y) and (9x-12y)
(9x^2-12y^2)=(9x+12y)(9x-12y)
=Length * Breadth
where length and breadth are two dimensions of rectangle
Therefore (9x+12y) and (9x-12y) are two dimensions of rectangle.

What single percentage change is equivalent to a 12% increase followed by a 14% decrease?
Answer:
3.68% decrease
Step-by-step explanation:
12% increase = 112% of the original value
112% as a decimal = 112/100 = 1.12
14% decrease = 100% - 14% = 86% of the original value
86% as a decimal = 86/100 = 0.86
Therefore, if you increase the number n by 12% and then decrease by 14%:
n × 1.12 × 0.86 = n × 0.9632
0.9632 as a percentage = 0.9632 × 100 = 96.32%
Therefore, the overall percentage change is 100% - 96.32% = 3.68% decrease

At a basketball game, 13% were supporting the visiting team. If 3045 people attending supported the home team, what was the total number of people attending the game?
Answer:
3500
Step-by-step explanation:
13% - 100% = 87
(3045 x 100) divided by 87 = 3500 people
The total number of people attending the game will be 3500.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
At a basketball game, 13% were supporting the opposing group. On the off chance that 3045 individuals going to uphold the host group.
The percentage of supporting the home team will be given as,
⇒ 100% - 13%
⇒ 87%
The total number of people attending the game will be given as,
⇒ 3045 / 87%
⇒ 3045 / 0.87
⇒ 3500

If a snail moves 1 1/2 feet in 3 3/4 hours, what is its speed in feet per hour? Show you
simplify your answer.
Answer:
2/5 feet an hour
Step-by-step explanation:
d=vt
1 1/2 or (3/2)=v(3.75hours or 15/4)
divide both sides by 3.75hours
0.4f/h=velocity/speed
or in fractions 2/5
The speed of the snail in feet per hour will be 0.40 feet per hour.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
If a snail moves 1 1/2 feet in 3 3/4 hours.
Convert the mixed fraction number into a decimal number. Then we have
1 1/2 feet = 1 + 0.5 = 1.5 feet
3 3/4 hours = 3 + 0.75 = 3.75 hours
Then the speed of the snail in feet per hour will be given as,
S = 1.50 / 3.75
S = 0.40 feet per hour
The speed of the snail in feet per hour will be 0.40 feet per hour.

A builder buys some new tools for his business costing £1200. The store offers 5% trade discount. How much do the new tools cost after the discount?
Answer:
£1140
Solving steps:
Question: A builder buys some new tools for his business costing £1200. The store offers 5% trade discount. How much do the new tools cost after the discount?
Find: How much do the new tools cost after the discount?
Solution:
Step 1: find the value of the percentage
=> £1200 × 5/100
=> 1200/1 × 5/100
cancel the 0 of the denominators of 100 and 1200
=> [tex] \frac{12}{1} \times \frac{5}{1} [/tex]
=> [tex] \frac{60}{1} [/tex]
=> [tex]60[/tex]
Step 2: Substract the value which is 60 to 1200
=> 1200 - 60
Substract 60 from 1200
=> 1140
therefore after discount it cost £1140

please help me guys
Step-by-step explanation:
midpoint : it is the point in the middle marking half of the total distance.
therefore,
1)
EV = LE = LV/2
10 = 5m
m = 2
2)
LR = RO = LO/2
n + 4 = 12
n = 8
3)
LER and LVO are similar triangles. that means they have the same angles, and the ratio of one corresponding pair of lines or sides between both triangles is the same for all corresponding line pairs.
we know e.g. LE/LV = 1/2.
the same ratio applies then to ER/VO = 1/2 = 18/20p.
18/20p = 1/2
18 = 20p/2
2×18 = 20p
36 = 20p
p = 36/20 = 9/5 = 1.88888888888...
4)
VL = 2×EL = 2×10 = 20
5)
LO = 2×RO = 2×12 = 24
6)
as we have already calculated for 3) :
VO = 36
7)
36 + 20 + 24 = 80
8)
10 + 12 + 18 = 40
9)
remember, the and angles in similar triangles.
LVO = 52°
10)
all angles around a single point in one side of a line are together 180°.
in this case there are 2 angles around E : LER and VER.
VER = 180 - LER = 180 - 52 = 128°
