Answer:

1.72 grams.

Step-by-step explanation:

We have been given that Gomez found the masses of three rocks for a science project. The first rock had a mass of 19.28 grams the second rock had a mass of 25.3 grams and the third rock had a mass of 46.3 grams.

First of all, we will add the masses of 1st and 2nd rock to find the combined mass of both rocks.

\text{Combined mass of 1st and 2nd rock}=\text{19.28 g+25.3 g}

\text{Combined mass of 1st and 2nd rock}=\text{44.58 g}

Now we will subtract the combined mass of both rocks from the mass of 3rd rock.

\text{Difference of mass }=\text{46.3 g}-\text{44.58 g}

\text{Difference of mass }=\text{1.72 g}

Therefore, the mass of the 3rd rock is 1.72 grams greater than the combined mass of the other two rocks.

Which of the following could be the graph of y = –xn where n is odd?
mina [271]

Answer:

Step-by-step explanation:

I think you meant y = -x^n, where ^ denotes exponentiation.

If n is odd, the graph begins in Quadrant II and decreases through the origin into Quadrant IV.  This is true of -x, -x^3, -x^5, and so on.

A flagpole is at the top of a building. 300 feet from the base of the building, the angle of elevation of the top of the pole is
Grace [21]

Answer: We can use tangent here to find the length of the flagpole

First, find the length of the building + the flag pole

tan 32 = x/300

x=300tan32=187.460805573

(length of building + flagpole)

find length of building

tan 30 = x/300

x=173.205080757

subtract

187.460805573-173.205080757=14.255724816

round, length of flagpole = 14 feet

I need help asap with this
tatyana61 [14]

Answer:

51°

Step-by-step explanation:

Given

<QPR = 39°

<PQR = 90° ( inscribed angle in semi circle)

Now

<QPR + <PQR + <PRQ = 180° { being sum of angles of triangle)

39° + 90° + <PRQ = 180°

<PRQ = 180° - 39° - 90°

<PRQ = 51°

Hope it will help :)
