Answer:
Step-by-step explanation:
Let the cost of apples be x
<u>Then we have equation:</u>
- (9 - 1.5)x = 15
- 7.5x = 15
- x = 15/7.5
- x = 2
<u>Cost of apple:</u> $2 per pound
A sum of direct benefits and indirect benefits that an employee receives from an employer. Hope google is right XD
Given the fraction of the students that can recognize all 26 letters, the number of student that still needs to learn the entire alphabet is 21.
<h3>How many students still needs to learn the entire alphabet?</h3>
Given that;
Number of students enrolled (no English) at ABC n = 150
6/7 of the students can recognize all 26 letters.
Number of students that can recognize all 26 letters will be;
6/7 × n = ?
6/7 × 150 = 128.6 ≈ 129
Now, the number of student that still needs to learn the entire alphabet will be;
x = n - Number of students that can recognize all 26 letters
x = 150 - 129
x = 21
Therefore, given the fraction of the students that can recognize all 26 letters, the number of student that still needs to learn the entire alphabet is 21.

Answer:
u * v = 39 ⇒ 2nd answer
Step-by-step explanation:
* Lets explain how to solve the problem
- u and v are two vectors
- u * v means the scalar product of the two vectors
- The scalar product is a way of multiplying vectors
- The result of a scalar product is always a number not a vector
- Ex: If u = ai + bj ⇒ <a , b> and v = ci + dj ⇒ <c , d> then the scalar
product of them is ac + bd where ac + bd is a number
* Lets solve the problem
∵ Vector u = 13j ⇒ <0 , 13>
∵ Vector v = i + 3j ⇒ <1 , 3>
- Lets find the scalar product
∴ u * v = (0)(1) + (13)(3)
∴ u * v = 0 + 39
∴ u * v = 39
