Answer:
Selling Price= $90.75
(i) Original Price= $90.75/0.75= $ 121.00
(ii) 1 Book= $90.75
10 Books= $90.75*10= $907.50
Total Amount Paid= $907.50*1.16 =$1052.70

What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given an expression as;
[tex]27^{-1/3} = \frac{9^{1/4} }{3^{r + 1}}[/tex]
Now we can see that
27 = 3³
9 = 3²
Then the power are 3(-1/3) = -1
3(1/4) = 3/4
So we have;
[tex]3^{-1} = \frac{3^{2/4} }{3^{r + 1}}\\\\3^{-1} =3^{1/2 -r - 1} \\\\3^{-1} =3^{1 -2r - 2 /2}\\\\3^{-1} =3^{-2r - 1/2}[/tex]
So,
-2 = -2r - 1
-2r = -1
r = 1/2

what is the circumfrence of a circle with a radius of 4 inches. Use 3.14 for pi.
Answer:
25.12 in.
Step-by-step explanation:
Circumference formula: pi*2*radius
radius=4, so
3.14*2*4=25.12
In ΔIJK, i = 340 cm, ∠I=120° and ∠J=59°. Find the area of ΔIJK, to the nearest 10th of a square centimeter.
The area of triangle IJK is 999.8 square centimeters
The given parameters are:
[tex]\angle I = 120^o[/tex]
[tex]\angle J = 59^o[/tex]
[tex]i = 340cm[/tex]
Start by calculating the length of side j using the following sine ratio
[tex]\frac{i}{\sin(I)} = \frac{j}{\sin(J)}[/tex]
Make j the subject of the formula
[tex]j = \sin(J) \times \frac{i}{\sin(I)}[/tex]
Substitute known values
[tex]j = \sin(59) \times \frac{340}{\sin(120)}[/tex]
Evaluate the expression
[tex]j = 337[/tex]
Next, calculate angle K using the following sum of angles formula
[tex]\angle I + \angle J + \angle K =180[/tex]
Substitute known values
[tex]120 + 59 + \angle K =180[/tex]
[tex]179 + \angle K =180[/tex]
Subtract 179 from both sides
[tex]\angle K =1[/tex]
The area of the triangle is:
[tex]Area = \frac{1}{2} ij \times \sin(K)[/tex]
So, we have:
[tex]Area = \frac{1}{2} \times 340 \times 337 \times \sin(1)[/tex]
Evaluate
[tex]Area = 999.8[/tex]
Hence, the area of triangle IJK is 999.8 square centimeters

50a3b-8ab factor the expression completely. part a: factor out the gcf (5 points) part b: factor the difference of perfect squares (5 points)
Answer:
Step-by-step explanation:
50a³b = 2⋅5²a³b
8ab = 2³ab
GCF = 2ab
50a³b - 8ab = 2ab(5²a² - 2²)
5²a² - 2² = (5a - 2)(5a + 2)

What is the length, in feet, of the diagonal of a square with 8-foot sides? Round to the nearest tenth.
Answer:
11 feet
Step-by-step explanation:
Length of diagonal of square of side a = √2a
Here value of a = 8 feet
Therefore length of diagonal d = √2×8 = 1.414×8 = 11.312 feet
So after rounding to the nearest tenth the length of diagonal becomes 11 feet

To find:
The value of the given expression into a single power.
Solution:
Given that,
[tex]\dfrac{(-24)^5}{(-24)}[/tex]
It can be rewritten as:
[tex]\dfrac{(-24)^5}{(-24)}=(-24)^{5-1}[/tex] [tex][\because \dfrac{a^m}{a^n}=a^{m-n}][/tex]
[tex]\dfrac{(-24)^5}{(-24)}=(-24)^{4}[/tex]
Therefore, the required expression is single power is [tex](-24)^{4}[/tex].

of an hour babysitting. What is her hourly rate?
Simplify your answer and write it as a proper fraction, mixed number, or whole number.
Answer:
$10
Step-by-step explanation:
Her hourly rate is 10 because if she earned $5 for half and our or 30 minutes that means to get to 1 hour multiply by 3 so you get. $10 per hour
Answer:
$10 per hour.
Step-by-step explanation:
$5 = 1/2 an hour | 30 minutes
So if you were to multiply $5 by 2 you'd get $10 which would make 1 whole hour.

Help a girl out Jamal plans to attend a 4-year private university. He will receive $8,200 in scholarships and grants each year, and he will earn $1,900 each year through a work study program. Jamal's family will contribute $21,000 each year. How much will Jamal need to contribute?
Answer:
Jamal contribution = Total fee - scholarship & grant - study program earnings - family contribution
Step-by-step explanation:
Let total fee = x
Jamal contribution = x - 8200 - 1900 - 21000
= x - 31100
Her fee above & beyond 31100 will have to be arranged by Jamal's own contribution
