Need help with this question?
Answers
Answer:
m∠A is 89°
Step-by-step explanation:
By circle theorem, two or more inscribed angles subtended by the same arc are equal
Therefore, from the diagram, we have;
Angle (5·x - 1)° and angle (4·x + 17)° subtends the same arc DC
∴ (5·x - 1)° = (4·x + 17)°
We can write the angles as follows since they are both in degrees
(5·x)° - 1° = (4·x)° + 17°
(5·x - 4·x)° = 17° + 1°
x = 18°
m∠A = (5·x - 1)°
∴ m∠A = (5 × 18 - 1)° = (90 - 1)° = 89°
m∠A = 89°.

What is the difference of the value of Lily's expression , 6x-3, when x=5 and the value of Pedro's expression when x=5 ? Show or explain how you got your answer.
Answers
Given Info : What is the difference of the value of Lily's expression , 6x-3, when x=5 and the value of Pedro's expression when x=5 .
To Find :- Show or explain how you got your answer.
Solution:-
The expression is 6x-3 , and we need to find its value at x = 5 , On putting x =5 we have
6*5-3 = 30-3 = 27.
This value will come same in case of Pedro, therefore our required answer is 5
When a number is multiplied by 5 before subtracting from 78 the result obtained is the same as three times the sum of the number and 5 find the number
Answers
Answer:
x = 7.875
Step-by-step explanation:
Let the number = x
When a number is multiplied by 5 before subtracting from 78 the result obtained is the same as three times the sum of the number and 5 find the number
Hence,
78 -(x × 5) = 3(x + 5)
Expand the brackets
78 - 5x = 3x + 15
Collect like terms
78 -15 = 3x + 5x
63 = 8x
x = 63/8
x = 7.875
in 50 item test nestor got 95% correctly. how many correct answers did he get
Answers
Answer: 47.5 or just 47
Step-by-step explanation: Well, to start, set up a ratio.
x / 50 = 95 / 100
95 * 50 is 4750
4750 / 100 is 47.5.
Now, it's asking how many questions he got correct. You can't get 47.5 questions correct, it should be a whole number. Now, I don't know how the rules work with that question, but it is like 47.

Step-by-step explanation:
evalute sin 60. cos 30 sin +sin 30 .cos 60 what is the value of sin(30-60) what can you conclude
Answers
Answer:
See explanations below
Step-by-step explanation:
evaluate sin 60. cos 30 sin +sin 30 .cos 60 what is the value of sin(30-60) what can you conclude
According to the trigonometry identity
Sin 30 = 1/2
Sin 60 = √3/2
Cos 30 = √3/2
Cos 60 = 1/2
sin 60. cos 30 +sin 30 .cos 60
= √3/2(√3/2) + 1/2(1/2)
= √9/4 + 1/4
= 3/4 + 1/4
= 4/4
= 1
sin(30-60) = sin30cos60 - cos30sin60
sin(30-60) =1/2(1/2) - √3/2(√3/2)
sin(30-60) = 1/4 - √9/4
sin(30-60) = 1/4 - 3/4
sin(30-60) = (1-3)/4
sin(30-60) = -2/4
sin(30-60) = -1/2
hence the former fraction gives a positive values while the later gives a negative

A polynomial of degree 3 is multiplied by a polynomial of degree 5. What is the degree of the product?
Answers
Answer:
8
Step-by-step explanation:
The degree of a polynomial refers to the term with the highest exponent. Thus the highest exponent in a degree 3 polynomial is x3; for a degree 5 polynomial, it's x5. When you multiply
x3*x5 = x3+5 = x8.
So the product of a degree 3 polynomial and a degree 5 polynomial is a degree 8 polynomial.
Your leading term will result from the 3-degree term of the first polynomial, and the 5-degree term of the second. So you'll have something like ax3 * bx5. That will result in x3*x5=x8, so your product will have degree 8.
