What is the measure of AngleP to the nearest whole degree? 35° 52° 57° 72°.
You can use the law of cosine to find the measure of angle P.
The measure of angle P is given by
Option C : 57°
What is law of cosine?Let there is triangle ABC such that |AB| = a units, |AC| = b units, and |BC| = c units and the internal angle A is of θ degrees, then we have:
[tex]c^2 = a^2 + b^2 - 2ab\cos(\theta)}[/tex]
(c is opposite side to angle A)
Using the law of sines to find the measure of angle P in the given contextRefer to the attached figure below.
Using the cosine law, we get
|PQ| = a = 17 units, |QR| =length of opposite side to P = c = 15 units, |PQ| = b = 14 units.
Thus, let angle QPR be of θ degrees, then
[tex]cos(\theta) =\dfrac{a^2 + b^2 - c^2}{2ab} = 0.546\\\\\theta = arccos(0.546) = 56.9^\circ, -56.9^\circ[/tex]
triangle's angles are measured positive, thus, measure of angle P came out as 56.9 degrees or approx 57°
Thus,
The measure of angle P is given by
Option C : 57°

You're going to the store to pick up some milk and cereal and want to know how much cash to bring. You remember last time you went to the store, milk cost $3 and cereal cost $4. Should you estimate or find an exact amount of money to bring to the store?
Answer:
I would estimate the amount of cash to bring. I say this because when you think about it you have to pay taxes which would add more to the cost. So I would probably bring around $10

What should be added to –7mn+2m2+3n2
to obtain 5m2+2mn-9n2
The polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.
Addition of PolynomialsLike terms should be combined together when adding polynomials.
Let x represent the polynomial expression that would be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n².
Therefore:
–7mn + 2m² + 3n² + x = 5m² + 2mn - 9n².
x = 5m² + 2mn - 9n² - (-7mn + 2m² + 3n²)
x = 5m² + 2mn - 9n² + 7mn - 2m² - 3n²
Combine like terms together.
x = 3m² - 11n² + 9mn
Therefore, the polynomial to be added to –7mn + 2m² + 3n² to obtain 5m² + 2mn - 9n² is: 3m² - 11n² + 9mn.

Here are the first four terms of an arithmetic sequence. 3,10,17,24. Is 150 a term in this sequence?
Answer:
1046
Step-by-step explanation:
formula for arithmetic sequence is:
aₙ = a₁ + (n-1)d
a₁ = first value in sequence
n = term value
d = common difference
a(150) = 3 + (150-1)7
= 3+1043
= 1046
150 is a term in this sequence, its 22nd of the sequence
What is arithmetic sequence?An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.
If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:
a, a + d, a + 2d, ... , a + (n-1)d, ...
Its nth term is
T_n = a + (n-1)d
(for all positive integer values of n)
And thus, the common difference is
T_{n+1} - T_n
for all positive integer values of n
Given;
The arithmetic sequence; 3,10,17,24
D= 10-3=7, a=3
150=3+(n-1)7
150=3+7n-7
150=7n-4
150+4=7n
7n=154
n=154/7
n=22
Therefore, 150 is 22nd term of the sequence.

The average of six weights is 12 kilograms. Another weight of 5 kilograms is added to the scale. What is the average of the seven weights?
Answer:
Hi there! Your answer here is 11kg - the average of the seven weights is 11kg. To find the average of a group of numbers, you add all of the numbers (12, 12, 12, 12, 12, 12, 5), then divide by the count of those numbers (7).
12 + 12 + 12 + 12 + 12 + 12 + 5 (or 12*6 + 5) is equal to 77.
77 / 7 = 11.
So the average of the seven weights is 11kg.

how do you solve 2.95/6 = x/50
Answer:
x=24.583
Step-by-step explanation:
first, find a common multiple of both 50 and 6. I used 150, I turned 2.95 into 73.75. so 73.75/150 reduced into '50s would be 24.583. or you can just say 2.95/6= 24.58/50. you can also use an online calculator if you believe that this is incorrect

We can define a line of reflection as the line in which a shape is reflected, or we can say that it is the mirror in which the shape is reflected. The line of reflection is the perpendicular bisector of any pair of corresponding points. If you want to join sets of corresponding points on the object and image, then

well, we know it's centered at (-2 , 1) and it passes through (-4 , 1), if it passes through there, that means that the distance from the center to (-4 , 1) must be its radius.
