Answer:
Answer A is correct. (x + 6)(x - 5) = x^2 + x - 30.
Step-by-step explanation:
Note that -30 = (-5)(6) and (5)(-6). This quadratic can be factored easily:
x^2 + x - 30 = (x + 6)(x - 5) is correct because 6x - 5x = x, the middle term of x^2 + x - 30.
Setting each factor equal to zero, one by one, we get:
x + 6 = 0 => x = -6, and x - 5 = 0 => x = 5
Answer A is correct.

Answer: x - 2.60(2) + x + x - 2.60
Step-by-step explanation:
Aleekah’s amount is x, as identified by the problem. If Barika earn less than 2.60 than Aleekah, then you would take away 2.60 from x, thus x - 2.60. If (x - 2.60) is how much Barika earned and James earn twice that amount, then he would have ((x - 2.60)*2)

Answer: C = 9
Step-by-step explanation:
Answer:
c=10.6
Step-by-step explanation:
In this we need to find c and we know that this is a right triangle
Therefore, I can use the Pythagorean Theorem which is a^2 + b^2 = c^2.
using this we then plug in a=8 and b=7 while c is the hypotenuse.
Now the equation is now 8^2 + 7^2 = c^2. We then solve for c.
8^2 + 7^2 = c^2
64 + 49 = c^2
113 = c^2
√113 = c
c = 10.630145...
Since the questions asks to round to the nearest tenth then the answer would be 10.6

86% of a university's freshman class are majoring in Computer Science. If 8514 students in the freshman class are Computer Science majors, how many students are in the freshman class?
Answer:
9900 Students
Step-by-step explanation:
Divide 8513 by .86 to show the rest of the freshman class.
You can check by doing 9900 times .86 to see %86 of 9900
Total there are 9900 students are in the freshman class.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Given that, 86% of a university's freshman class are majoring in Computer Science.
8514 students in the freshman class are Computer Science majors.
Let the number of students are in the freshman class be x.
Here, 86% of x=8514
86/100 ×x=8514
86x=851400
x=851400/86
x=9900
Therefore, total there are 9900 students are in the freshman class.

Tank A has a diameter of 10 ft and a height of 3 ft. Tank B has a diameter of 6 ft and a height of 8 ft
Answer:
1,Area = πr² Circumference = 2 πr So first we solve for r from area: 25 π = πr² 25 = r² r = 5 So we know that radius is 5 cm. Now substitute r to 5 in circumference formula: C = 2π(5) = 10π
