Karen buys some new clothes for $89.40 + tax. The tax rate is 6.4%. What is her final price? *
Answer:
$95.10
Step-by-step explanation:
well take 89.40 and multiply by 6.4%. then add.
89.40 x 6.4% is 5.7. we can make out 5.7 to be $5.70.
$89.40 + $5.70 is 95.1 or $95.10

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°

The owner of a garden center pays $12 for each birdbath. She sells them for 55% more than she paid. Decide whether each expression represents the selling price for b birdbaths.Choose Yes or No for each expression.A.12b1 1. 55(12b) u Yesu Nob. 12(0 . 45b) u Yesu Noc.12b(1. 55)u Yesu Nod. 12(0 . 55b) u Yesu Noe. 12b(1 1 0.55)u Yesu No
Answer:
[tex]Selling\ Price = 12b(1.55)[/tex]
Step-by-step explanation:
Given
[tex]Cost\ Price = \$12[/tex]
[tex]Selling\ Price = 55\%\ more[/tex]
Required
Write an expression for the selling price for b birdbaths
This selling price for 1 birdbath is calculated as:
[tex]Selling\ Price = Cost\ Price + 55\% * Cost\ Price[/tex]
Substitute 12 for Cost Price
[tex]Selling\ Price = 12 + 55\% * 12[/tex]
Factorize:
[tex]Selling\ Price = 12(1 + 55\%)[/tex]
Express percentage as decimal
[tex]Selling\ Price = 12(1 + 0.55)[/tex]
[tex]Selling\ Price = 12(1.55)[/tex]
For b birdbaths, the selling price is:
[tex]Selling\ Price = 12(1.55) * b[/tex]
[tex]Selling\ Price = 12b(1.55)[/tex]
The options are not clear; However [tex]12b(1.55)[/tex] answers the question.

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.

On last week's math test, 32 students received passing grades and 16 students did not
receive passing grades. What is the ratio of the number of students who passed the test to
the total number of students who took the test?
A
11 / 1
B
2/3
C
3/2
D
2/1
Answer:
Option B. The ratio of the number of students who passed the test to
the total number of students who took the test is 2/3
Step-by-step explanation:
Firstly, we have to find the total number of students who took the test, we can do that by adding the number of students who passed and the number of students who did not pass, so ...
32 + 16 = 48
Now we just write down the ratio between the number of students who passed the test and the total number of students who took the test. So we get
32/48
Now we just simplify and get...

Bruce drove 360 miles in 6 hours. If he continues at a consistent speed, how many more hours would he need to drive another 300 miles?
Answer:
5 hours
Step-by-step explanation:
If he drove 360 miles in 6 hours, that means he drives 60 miles per hour.
300 divided by 60 is 5, so he will need to drive for 5 more hours
Answer:
5 hours
Step-by-step explanation:
Find his speed in miles per hour:
360/6
= 60
So, his speed is 60 mph
To find how many more hours he would have to drive another 300 miles, divide 300 by 60:
300/60
= 5
So, he would have to drive 5 hours

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.

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.
