Answer: 15%
Step-by-step explanation:
From the question, we are informed that a survey results of a middle school shows that 3/20 of the students played football.
The percentage of the students that play football in this schools would be calculated as multiplying the fraction by 100. This will be:
= 3/20 × 100
= 3 × 5
= 15%
Answer:
This quadratic equation has 2 solutions.
Step-by-step explanation:
I assume the '?' in your question is meant to be power 2 (²), or else it would not be a quadratic equation. You could write it using the superscript version of 2.
We can solve this equation by expressing it in the form: ax² + bx + c
x² + 9x= -8
x² + 9x + 8 = 0
Now if you know the discriminant, you can simply plug in your values of a, b, and c to see how many solutions there are.
In this case, you would not need the discriminant as there are whole-number factors and hence this can simply be factorised.
x² + 9x + 8 = 0
(x + 8)(x + 1) = 0
For this equation to be true (= 0), x can equal -8 OR -1.
Hence, this quadratic equation has 2 solutions.
Answer:
The value x would equal to 2
11 divided by 5.5 = 2
5.5 x 2 =11

Answer:
Start with y=mx+b since it is perpindicular to the slope of -3/4 the new slope is 3/4. so now we have m=4/3 next we subsitute known values in (0,-1). We multiply 0 by 3 next we have -1=0+b so be has to be -1 so your awnser is
y=4/3-1
