Answer:

$32 units^2$

Step-by-step explanation:

To find the area of this irregular shape, you can split it into 3 triangles, and 1 square.

The formula for finding the area of a triangle is:

$A = \frac{1}{2} bh$

The formula for finding the area of a square is:

$A = lw$

Finding area of large triangle:

$A = \frac{1}{2} (4)(10)\\\A = 20$

Finding area of bottom left triangle:

$A = \frac{1}{2} (2)(2)\\A=2$

Finding area of last triangle (bottom right):

$A = \frac{1}{2} (2)(6)\\A=6$

Finding area of square:

$A = (2)(2)\\A = 4$

Answer:

Step-by-step explanation:

Area of a big right triangle = 1/2 * 4 * (2+2+6) = 1/2 * 4 *10 =20

Area of a left right triangle = 1/2* 2*2 = 2

Area of a right right triangle = 1/2 * 6*2 =6

Area of a square = 2*2 = 4

All together:

20+ 2+6+4 =32

Carissa also has a sink that is shaped like a half-sphere. The sink has a volume of 2000/3[pie] in^3. One day, her sink clogged.

Kobotan [32]

I have these same questions but the way i solved them i did

A: 1/3 x 3.14 x 2*2 x 8 = 32/3 = 2000 divided by 32 = 63 scoops
The formula is 1/3 x 3.14 x r*2 x h
B: 1/3 x 3.14 x 8*2 x 8 = 128/3 = 2000 divided by 128 = 16 scoops

Which is equal to P-R?

lorasvet [3.4K]

<h3>Answer: Choice B</h3>

With matrix subtraction, you simply subtract the corresponding values.

I like to think of it as if you had 2 buses. Each bus is a rectangle array of seats. Each seat would be a box where there's a number inside. Each seat is also labeled in a way so you can find it very quickly (eg: "seat C1" for row C, 1st seat on the very left). The rule is that you can only subtract values that are in the same seat between the two buses.

So in this case, we subtract the first upper left corner values 14 and 15 to get 14-15 = -1. The only answer that has this is choice B. So we can stop here if needed.

If we kept going then the other values would be...

row1,column2: P-R = -33-16 = -49

row1,column3: P-R = 28-(-24) = 52

row2,column1: P-R = 42-25 = 17

row2,column2: P-R = 35-(-30) = 65

row2,column3: P-R = -19-36 = -55

The values in bold correspond to the proper values shown in choice B.

As you can probably guess by now, matrix addition and subtraction is only possible if the two matrices are the same size (same number of rows, same number of columns). The matrices don't have to be square.

An angle measures 47.2° less than the measure of its supplementary angle. What is the measure of each angle? on ixl

SVEN [57.7K]

Answer:

The measure of one angle is $113.6^o$ , and the measure of the other one is $66.4^o$

Step-by-step explanation:

Recall that supplementary angles are those whose addition renders $180^o$

We need to find the measure of two such angles whose difference is precisely $47.2^o$ .

Let's call such angles x and y, and consider that angle x is larger than angle y, so we can setup the following system of equations:

$x+y=180^o\\x-y=47.2^o$

We can now solve this by simply combining term by term both equations, thus cancelling the term in "y", and solving first for "x":

$x+y=180^o\\x-y=47.2^o\\\\2x=180^o+47.2^o\\2x=227.2^o\\x=113.6^o$

So, now we have the answer for one of the angles (x), and can use either equation from the system to find the measure of angle "y":

$y=180^o-x\\y=180^o-113.6^o\\y=66.4^o$
