Find each unit rate.<br> 4/5of a chapter in 3/10 hour

ZanzabumX [31]

Answer:

8/3mph

Step-by-step explanation:

you must multiply both fractions by the reciprocal of 3/10 which is 10/3

(4/5 * 10/3) / (3/10 * 10/3)

(40/15) / (30/30)

(8/3) / 1

8/3 /1 = 8/3

In triangle ABC, c = 9 m/_B = 65° and a = 105. Find b.

tresset_1 [31]

Answer:

b = 101.52

Step-by-step explanation:

b^2 = a^2 + c^2 - 2ac CosB

b^2 = 105^2 + 9^2 - 2(105)(9) Cos 65°

b^2 = 11 106 - 798.75

b^2 = 10 307.25

b = 101.52

If you have a cube measuring 1 unit on each side, how many of those cubes would fit into a space 2 units by 3 units by 4 units

alisha [4.7K]

Given:

Measure of a cube = 1 unit on each side.

Dimensions of a space 2 units by 3 units by 4 units.

To find:

Number of cubes that can be fit into the given space.

Solution:

The volume of cube is:

$V_1=a^3$

Where, a is the side length of cube.

$V_1=(1)^3$

$V_1=1$

So, the volume of the cube is 1 cubic units.

The volume of the cuboid is:

$V_2=l\times b\times h$

Where, l is length, w is width and h is height.

Putting $l=2,b=3,h=4$ , we get

$V_2=2\times 3\times 4$

$V_2=24$

So, the volume of the space is 24 cubic units.

We need to divide the volume of the space by the volume of the cube to find the number of cubes that can be fit into the given space.

$n=\dfrac{V_2}{V_1}$

$n=\dfrac{24}{1}$

$n=24$

Therefore, 24 cubes can be fit into the given space.

Answer:

Step-by-step explanation:

11 no

46+4x=90 degree(being perpendicular)

4x=90-46

x=44/4

x=11

12 no

They are complementary angles

6 no

angle B+27=180 degree(being straight line)

angle B=180-27

angle B=153

10 no

angle 38 +angle DFE=180 degree(being supplementary)

angle DFE=180-38

angle DFE=142 degree

5 no

They are vertically opposite angles.

7 no

angle AGF and angle CGD (because they have common arm and vertex)
