What is the slope of the line shown in the graph? <br> A.-3/2<br> B.-1/2<br> C.3/2

Varvara68 [4.7K]

I think answer is A
Because slope=rise/run
Rise is 3
Run is 2
But it will be negative because of the direction of slope

Find the total volume of the composite figure below. Round to the nearest thousandth.

cestrela7 [59]

Answer:

The volume of the composite figure is approximately 3567.198 cubic feet.

Step-by-step explanation:

The composite figure consists in the combination of a right cone and a cuboid. The volume of the composite ( $V$ ), in cubic feet, figure can be determined by this expression:

$V = \frac{1}{3}\cdot \pi \cdot r^{2}\cdot h + w\cdot H \cdot l$ (1)

Where:

$r$ - Radius of the circle of the right cone, in feet.

$h$ - Height of the cone, in feet.

$w$ - Width of the cuboid, in feet.

$H$ - Height of the cuboid, in feet.

$l$ - Length of the cuboid, in feet.

If we know that $r = 10\,ft$ , $h = 10\,ft$ , $w = 20\,ft$ , $H = 7\,ft$ and $l = 18\,ft$ , then the volume of the composite figure is:

$V = \frac{1}{3}\cdot \pi \cdot (10\,ft)^{2}\cdot (10\,ft) + (20\,ft)\cdot (7\,ft)\cdot (18\,ft)$

$V = \left(\frac{1000\pi}{3} + 2520\right)\,ft^{3}$

$V \approx 3567.198\,ft^{3}$

The volume of the composite figure is approximately 3567.198 cubic feet.

Find the distance between the two points rounding to the nearest tenth

mixas84 [53]

Answer:

8.54

Step-by-step explanation:

formula:

$d=\sqrt{(x2-x1)^2 + (y2-y1)^2}$

$d=\sqrt{(-4 - (-7))^2 + (0-(-8))^2}$

$d=\sqrt{3^2 + 8^2}$

$d=\sqrt{9 + 64}$

$d=\sqrt{73}$

d= 8.54

Answer:

3. <0, <BOA, <ABO

4. <E, <NED,<DEN

here you guess and judge by your basic knowledge of angles and guess the angle measurement. and as far as the angle names with three points there should be three names and so the angle you are measuring must always be in the middle and ya :))
