6. The triangles shown are congruent. Find the measure of P.



A 43

B 32

C 105

D 37.5

Answers

Answer: B-32

Step-by-step explanation:

Hello! All angles of a triangle add up to 180 degrees.  Since triangles add up to 180 degrees, you know that the measure of angle m in the first triangle is 105 degrees.  Because all sides in congruent triangles and all angles in congruent triangles are also congruent, you know that the second triangle has to have the same angle measurements as the first. P or Q could have the angle measurements of 32 degrees or 43 degrees. Q is the angle with 43 degrees because it is clearly the longer side and looks like the first triangle's side with 43 degrees.  P is the angle with 32 degrees because it is the shorter side.

P is 43 degrees. Side XM is congruent to side PR so we know angle M and R are congruent and P and X are congruent. X = 43 = P

Answers

Answer:

x=1

Step-by-step explanation:

By looking at the equation we can see that the x intercept stays the same, so this is a vertical slope. in slope intercept form (y=mx+b) this looks like

x=b

and since we can see the two points x is always 1, we know that b is 1 so

Like the other Hawaiian Islands, Loihi is volcanic. But unlike most of the other islands, it is still being formed. Currently, the island is more than 3,000 m high. It has about 969 m to go before it reaches sea level. If it keeps growing at its current rate, it should become visible above the surface of the ocean sometime in the next 10,000 to 100,000 years.

Question 1:
If Loihi reaches sea level in 10,000 years, what would its average rate of growth per year be?

Question 2:
What would its average rate of growth per year be if it reaches sea level in 100,000 years?

If you answer these 2 questions correctly I will give you 5 stars and thanks.

Answers

Answer:

Step-by-step explanation:

1. Since the sea level is 10,000 the average growth rate per year would be 2 mm.

2. 1000m because 10/x = 1000/100000

1000x=1000000

x=1000000/1000

x=1000

The locations of each irrational number are the following:

√16 - Point a

√27 - Point b

√32 - Point c

What is Number line?

Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.

Since, √16 is an irrational number that is also rational,

Since, 4² = 16

Then,  √ 16 must be point a.

Both √27 and √32 are greater than √25 = 5 and less than √36 = 6. Then, both are between 5 and 6.

Since, √27 < √32

Hence,  √27 must be point b and √32 must be point c.

Thus, The locations of each irrational number are the following:

√16 - Point a

√27 - Point b

√32 - Point c

Answers

Answer:

Yes, he has enough money to buy everything in his cart.

Step-by-step explanation:

If he spent $46 on groceries and has to pay a 6% sales tax, that would just be 6% of $46, and that's $2.76. 46+2.76=48.76. His total is $48.76, which is under $50.

Yes he can afford to buy everything he wants 46$ even with a 6% sales tax is only 2.76$
