Answer:
Please check the explanation.
Step-by-step explanation:
6)
Given ΔMNO ≅ ΔPQR
As congruent parts of congruent triangle are congruent.
and also given
so
m∠N = m∠Q
2x+6 = 4x+12
4x-2x = 6-12
2x = -12
Divide both sides by 2
x = -6
Thus, the value of x = -6
Therefore, option 'A' is true.
7)
Given ΔABC ≅ ΔDEF
As congruent parts of congruent triangle are congruent.
and also given
so
AB = DE
4v+2 = 6v-4
6v-4v = 2+4
2v=6
Divide both sides by 2
v = 3
Thus, the value of v = 3
Therefore, option 'A' is true.
Answer:
The probability that a student earns a grade of A is 1/7.
Let E be an event and S be the sample space. The probability of E, denoted by P(E) could be computed as:
P(E) = n(E) / n(S)
As the total number of students = n(S) = 35
Students getting the grade A = n(E) = 5
So, the probability that a student earns a grade of A:
P(E) = n(E) / n(S)
= 5/35
= 1/7
Hence, the probability that a student earns a grade of A is 1/7.
Keywords: probability, sample space, event
For the flag pole question it should be:
They are congruent.
Hey I'm sorry about not answering the next question. I just noticed your questions and pleads for help. And I felt really bad nobody was responding to you. So I was looking at the rest of your questions and tried to answer as much as I can. I hope you get more help aswell.
Answer:
(36) (x+6) (-10 or -2) i got this right on (ed)
Step-by-step explanation:
1 Add to both sides of the equation. The value of in this equation is 36.
2 Write the left side of the equation as a binomial squared. The left side of the equation becomes (x +6)2.
3 Use the square root property of equality.
4 Isolate the variable: x = -10 or -2
Answer: There will be 22.694 grams of initial mass remains after 50 years.
Step-by-step explanation:
Since we have given that
We need to find the quantity of initial mass remains after 50 years.
So, t = 50 years,
We get that
Hence, there will be 22.694 grams of initial mass remains after 50 years.
