Help me please I don’t have a lot of time please.
oi can someone help me with this one ^{2}-12x-28=0
This is still pretty confusing for me
Answer:
Both answers should be -2 and 14.
Step-by-step explanation:
Using the quadratic formula:
[tex]x^{2}-12x-28=0\\\\x=\frac{-(-12)+-\sqrt{(-12)^2-4(1)(-28)} }{2(1)}\\\\x= \frac{12+-\sqrt{144+112} }{2}\\\\x= \frac{12+-\sqrt{256} }{2}\\\\x= \frac{12+-16 }{2}\\\\x=6+-8[/tex]
Therefore:
[tex]x_{1} =6+8=14\\x_{2}=6-8=-2[/tex]

Answer:
x = 9.83
Step-by-step explanation:
Taking 55 as the reference angle,
hypotenuse (h) = 12
perpendicular (p) = x
Sin 55 = p/h
Sin 55 = x / 12
x = Sin55 x 12
x = 9.83

In a race 24 out of 25 cyclists finished in less than 51 minutes what percentage of cyclists finished the race in less then 51 minutes
Answer: 96%
Step-by-step explanation:
There are 25 total cyclists and 24 of those finished the race in less than 51 minutes. The question would like this 24 to be expressed as a percentage of 25.
In percentage this would be:
= Number of cyclists who finished in 51 minutes / Total number of cyclists * 100%
= 24 / 25 * 100%
= 96%

Em uma escola,estudam em tres periodos 1256 meninas e 1593 meninos. quantos alunos estudam nessa escola?
Answer:
I will answer in English.
This can be translated to:
In a school, 1256 girls and 1593 boys study in three periods. how many students study at that school?
This means that we have a total of:
(1256 + 1593) students = 2849 students, divided in 3 periods.
So the total number of students in that school is 2849
And the number of students per period is:
2849/3 = 949.7
Because we can only have whole numbers here, we can say that in each period there are around 950 students.

look at the triangle. What is the approximate value of x
Answer:
relationship between perpendicular and base is given by tan angle
tanx°=p/b
tanx°=45/30
x°=tan-¹(45/30)=56.30=56
Answer:
0.03
Step-by-step explanation:
In given triangle,
perpendicular(p)=45
base(b)=30
x=?
We know,
tanx = p/b
or, tanx = 45/30
or, tanx = 3/2
or, x = tan-1(9/7)
or, x = 56.3099324740202 i.e. 56 approximately
