Answer:
a)
Tom
Tax = (11/100) × 13
Tax = $1.43
Tom paid 13 +1.43 = $14.43
Lyn
Tax = (9/100)× 21
Tax = $1.89
Lyn paid 21 + 1.89 = $22.89
b) Lyn paid more for taxes.
Find tan A.
A. tanA = 12/5
B. tanA = 5/12
C. tanA = 13/5
D. tanA = 5/13
Answer:
tanA=BC/AC
BC=20
AC=48
so,BC/AC=20/48=5/12
the average of 5 numbers is 7. when one more number is added the average becomes 10. what number was added?
Answer:
13
Step-by-step explanation:
for example, Sum of 5 no. = 7×5=35
Sum of 8 no. = 8.5×8=68
Sum of added all three no. = 68 - 35 = 33
average of three new numbers = 33/3=11
The number 25 is added then the average becomes 10.
What is an average?The average is defined as the ratio of the sum of the data to the total numbers of the data.
Average = ( Sum of the numbers ) / ( number of the data )
Given that the average of 5 numbers is 7. when one more number is added the average becomes 10.
The number added is calculated as:-
Sum of the numbers = 5 x 7 = 35
Let x is the number added.
Sum of the numbers = 35 + x
We know that some of the numbers = 10 x 6
35 + x = 10 x 6
35 + x = 60
x = 60 - 35
x = 25
Hence, the number added is 25.

Please help! I need help fast.
Answer:
240 cm^3
Step-by-step explanation:
The solid is composed by two rectangular parallelepipeds. To find the total volume we have to find the volume of the two solids and added up.
To find the volume of a parallelepiped we have to use this formula:
V = base surface x height
The area of rectangle is : base x width
So:
Area first rectangle: 4 x 6 = 24 cm^2
V = 24 x 7 = 168 cm^3
Area second rectangle: 4 x 2 = 8 cm^2
V = 8 x 9 = 72 cm^3
total volume = 168 + 72 = 240 cm^3

Answer:
According to the theorem of chords intersecting inside the circle,
1) 15 * 8 = 10 * x
120 = 10x
120/10 = x
12 = x
2) 21 * 10 = 14 * x
210 = 14 x
210/14 = x
15 = x
3)10 * 4 = 5x
40 = 5x
40/5 = x
8 = x
4) 5x * 2x = 10*9
10x^2 = 90
x^2 = 90/10
x^2 = 9
x = √9
x = 3
5)3x + 3 * 3x = 10 * 18
9 x^2 + 9x = 180
dividing the whole eq. by 9
x^2 + x = 20
x^2 + x - 20 = 0
x^2 + 5x - 4x - 20 = 0
x(x + 5) - 4(x + 5) = 0
x - 4 = 0 OR x + 5 = 0
x = 4 or x = -5
The length cannot be negative, so,
x = 4
ABCD is a square with an area of 49 cm2, and BE = 4.95 cm. Point E is the midpoint of 2 diagonal lines crossed inside the square.
Answer:
I suppose we want to find the side length of the square.
We know that:
The area of the square is 49cm^2
The distance between one of the vertices of the square and the middle of the square is:
BE = 4.95cm
Now let's remember some things.
For a square of side length L, the area is:
A = L^2
and the diagonal length is:
D = √(2)*L
In this case, we know that half of the diagonal is equal to:
BE = 4.95 cm
Then the diagonal is:
D = 2*BE = 2*4.95cm = 9.9cm
And for the diagonal formula, we have:
D = 9.9cm = √(2)*L
Then the side length is:
L = 9.9cm/√(2) = 7cm
And if we check the area of this square, is:
A = L^2 = (7cm)^2 = 49cm^2
So it checks.
Then we can conclude that the sidelength of the square is 7cm, which means that:
AB = 7cm
BC = 7cm
CD = 7cm
DA = 7cm

Calculate the distance between the points E=(-6,8) and N=(-1,5) in the coordinate plane. Give an exact answer (not a decimal approximation).
Answer:
6 units
Step-by-step explanation:
The formula for calculating the distance between two points is expressed as;
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given the coordinate points E=(-6,8) and N=(-1,5)
[tex]EN = \sqrt{(5-8)^2+(-1+6)^2}\\EN = \sqrt{(-3)^2+(5)^2}\\EN = \sqrt{9+25}\\EN = \sqrt{34}\\EN = 5.8\\EN \approx 6[/tex]
Hence the distance between the points is approximately 6 units

You and your friend decide to go to Red Robin to eat. You are both part of the rewards club and receive coupons in the mail. You have a coupon a coupon for 10% off the total bill. Your friend has a coupon for $5 off the total bill. Which coupon should you use to save the most money if the total bill was $29.90? *
A. the $5 off coupon
B. the 10% off coupon
C. either one
D. cannot be determined
Answer:
A. the $5 off coupon
Step-by-step explanation:
10% off would only be 2.99 off the bill making it 26.91 but the $5 would take off more
The coupon I would use to save the most amount of money on the total bill is my friend's coupon worth $5.
Which coupon should I use?Coupons reduce the price of an item. An item becomes cheaper after a coupon has been used. In order to determine the better coupon, calculate the price after each coupon has been used.
Coupon 1 : 10% x 29.9 = $3
Coupon 2 : 29.90 - $5 = $24.90

On Wednesday 72% of the costumers who bought gas at a gas station made additional purchases. There were 259 costumers made additional purchase?
Answer:
360 approx
Step-by-step explanation:
Given data
We want to find the total number of customers that bought gas
Let the total number of customers be x
So
72% of x = 259
let us solve for x
72/100*x= 259
0.72*x=259
x= 259/0.72
x= 359.72
Hence the actual number of customers is 360 approx

It is in between 0 to 12.
Answer:
√125 must be between 11 and 12.
Step-by-step explanation:
Identify perfect squares in the neighborhood of 125:
121 = 11^2 or √121 = 11
144 = 12^2 √144 = 12
√125 must therefore be between 11 and 12.
