Select all the expressions that represent a price discounted by 20% of the price of an item that originally cost d dollars
Options :
A. 0.8d
B. d-0.2
C. d-0.2d
D. 1-0.2d
Answer:
A. 0.8d ; d - 0.2d
Step-by-step explanation:
Given that:
Cost of item = d dollars
Discount on items = 20%
Expression represemting the discounted price :
(100% - 20%) x d
80% * d
0.8d
(100% - 20%) x d
(1 - 0.2)d
d - 0.2d

In ΔEFG, f = 42 inches, e = 39 inches and ∠E=43°. Find all possible values of ∠F, to the nearest degree.\
Answer:
The angle F = 47.25°
Step-by-step explanation:
Step(i):-
Given that f =42inches and e = 39 inches
Given that ∠E = 43°
By using sine rule
[tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{C}{sinC} = 2R[/tex]
[tex]\frac{e}{sinE} = \frac{f}{sinF}[/tex]
⇒ [tex]\frac{39}{sin43} = \frac{42}{sinF}[/tex]
Cross multiplication , we get
⇒ 39 sin F = 42 × sin 43°
[tex]sin F = \frac{42 X 0.68199}{39}[/tex]
⇒ sin F = 0.734459
Step(ii):-
⇒ sin⁻¹ (sin F)= sin ⁻¹ ( 0.734459)
⇒ F = 47.25
The angle F = 47.25°
if these two shapes are similar what is the measure of the missing length r?

The high temperatures, in degrees Fahrenheit, of 10 U.S. Cities during a day in October are listed below. 72, 50, 54, 66, 58, 79, 54, 99, 40, 68 What is the range of the temperatures? A. 54°F B. 59°F C. 62°F D. 64°F
Answer: B. 59°F
Step-by-step explanation:
Range = Maximum - MInimum.
From the given temperatures, Maximum temperature = 99 degrees Fahrenheit
Minimum temperature = 40 degrees Fahrenheit
Range = Maximum temperature - Minimum temperature
i.e. Range =99-40 = 59 degrees Fahrenheit
Hence, the range of the temperatures = 59°F i.e. B is the correct option.

General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS

Terms/CoefficientsStep-by-step explanation:
Step 1: Define
1/2(12x + 18) > 99
Step 2: Solve for x
[Multiplication Property of Equality] Multiply 2 on both sides: 12x + 18 > 198[Subtraction Property of Equality] Subtract 18 on both sides: 12x > 180[Division Property of Equality] Divide 12 on both sides: x > 15Here we see that any value x greater than 15 would work as a solution to the inequality.

Train A and train B leave a central station at the same time. They travel the same speed, but in opposite directions, with train A heading towards station A, and train B heading towards station B. Train A reaches station A after 4 h. Train B reaches station B after 3 1/2 h. Station A and Station B are 562.5 mi apart.
What are the rates of the trains?
Answer:
since the rate is the same for both trains, and we know that the distance train A travels plus the distance train B travels equals 562.5 miles, we can use the D(istance) = R(ate) * T(ime) formula to solve this.
Train A:
da = R * 4
Train B:
db = R * 3.5 (using 3.5 instead of 3 and 1/2)
Solve for R:
R * 4 + R * 3.5 = 562.5
7.5 * R = 562.5
R = 75
The trains are traveling at 75 miles per hour.
Step-by-step explanation:
Answer:
speed = distance / time
since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2
speed = 585/(13/2) = 90 miles per hour.

Accordingly to the Internet which knows everything a good rule of thumb is to plan for 5 to 10% waste when buying carpet how did the estimate to do
Answer:
Not bad
Step-by-step explanation:
According to the internet, there are a number of factors to consider before estimating your waste percentage when buying carpets.
You may have to check the shape of your room, if it has multiple walls or if it is just complicated. For this kind you can estimate a 20% waste factor.
But for uncomplicated rooms having the same width as the carpet, the rule of thumb is to add a 10% waste factor to the square footage area.

Write an expression that shows the multiplication of a two digit number between 1 and 10 and another two digit number between 1 and 10 (different from the first), whose product is greater than 8, but less than 10.
Answer:
Step-by-step explanation:
From the given information:
Let the first expression that contains two digit number i.e. after multiplying them together their result is greater than 8 but less than 10, let those numbers be:
= 5.5 × 1.5
= 8.25
And another expression that is different from the first but exhibit the same properties to be:
= 3.5 × 2.5 (since both entities are two digit numbers)
= 8.75
Given: ABCD is a parallelogram.
Prove: AB = CD and BC = DA
answers are in image.
Answer:
ASA theorem (angle side angle)
Step-by-step explanation:
ac is congruent to ac bc of reflexive property.
and bc you found the other two angles using alternate interior angle theorem, it's safe to use angle side angle. if two angles and a side is congruent between the two triangles, then the two sides are congruent.
