Answer:
269.50, you could search it up
The total amount that he will spend on his computer will be $269.5.
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 to one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
For his summer course, John has to have a computer. Since he is still enrolled in school, he receives a 30% discount off the computer's $385 price.
The amount of discount is calculated as,
⇒ 0.30 x 385
⇒ 115.5
Then the amount spent on the computer is calculated as,
⇒ 385 - 115.5
⇒ 269.5
The total amount that he will spend on his computer will be $269.5.

9. Jamie ha ahorrado $ 42 del dinero de su asignación para comprar libros. Si compra 5 libros a d dólares por libro, le quedarán 42 5d de su asignación. ¿Cuánto le queda si los libros cuestan $ 3.50 cada uno?
Answer:
$24.50
Step-by-step explanation:
Jamie has saved $ 42 of his allowance money to buy books. If you buy 5 books at d dollars per book, you will have 42- 5d left of your allowance. How much is left if the books cost $ 3.50 each?
We have the equation
42 - 5d = Amount of Allowance left
d = 3.50
Hence:.42 - 5 × 3.50
= $42 - 17.5
= 24.5
Simplify by combining like terms: 3x - 5 + 12x - 10

What is the law of sines ?
he Law of Sines (or Sine Rule) is very useful for solving triangles.
According to the law ,
When we divide side a by the sine of angle A
it is equal to side b divided by the sine of angle B
and also equal to side c divided by the sine of angle C
[tex]\rm \dfrac{a}{sinA} = \dfrac{b}{sinB} = \dfrac{c}{sinC}[/tex]
It is given that in Δ PQR
r = 4.9 cm
angle R = 21
angle P =104
Length of p needs to be found
Therefore by using above equation
[tex]\rm \dfrac{r}{sinR} = \dfrac{p}{sinP}[/tex]
[tex]\rm \dfrac{4.9}{sin21^{0}} = \dfrac{p}{sin104^{0}}[/tex]
p= 13.3 cm
Therefore the length of p, to the nearest 10th of a centimeter is 13.3 cm .

Answer: yes y=12 is a solution to y over -6
Step-by-step explanation: you simply have to put 12 in for y. 12 divided by -6 = -2.
[tex] \frac{12}{ - 6} = - 2 [/tex]
[tex] - \frac{2}{1} = - 2[/tex]
Therefore, y = 12 is the correct solution.
We get -2/1 from 12/-6 by diving the top and bottom by 6.

What is the sum of the greatest and least numbers below:
Answer:
1/6
Step-by-step explanation:
Step 1: Make remaining mixed numbers improper fractions:
8 1/5 = ((8*5)+1)/5 = 41/5
-8 2/5 = -((8*5)+2)/5 = -42/5
Step 2: Order fractions from least to greatest:
-26/3 <- Least
-42/5
-54/7
41/5
53/6 <- Greatest
Step 3: Find the sum of the least and greatest fractions:
Given: -26/3+53/6
Make equivalent fractions: -52/6+53/6
Rearrange: 53/6-52/6
Evaluate: (53-52)/6 = 1/6
Therefore, the sum of the greatest and least numbers is 1/6
