Determine if the following is parallel perpendicular or neither. y=2/3x-5 and 2x-3y=12

The following are the ages (years) of 5 people in a room:

Novosadov [1.4K]

Answer:

44

Step-by-step explanation:

mean = (13+15+12+16+14+X)/6 = 19

70+X=19×6

X=114-70=44

How many cubes with side lengths of 1/2 cm does it take to fill up the prism

ELEN [110]

24 cubes can filled up the prism

Solution:

The image of the question is attached below.

Given data:

Length of the prism = 2 cm

Breadth of the prism = 1 cm

Height of the prism = $$\frac{3}{2}$ cm

Volume of the prism = length × breadth × height

$$=2\times 1\times \frac{3}{2}$

$=3$ cubic cm

Volume of the prism = 3 cubic cm

Side length of the cube = $$\frac{1}{2}$ cm

Volume of the cube = side × side × side

$$=\left(\frac{1}{2}\right)^{3}$

$$=\frac{1}{8}$ cubic cm

Volume of the cube = $\frac{1}{8}$ cm

$$\text{Number of cubes} =\frac{\text{Volume of the prism}}{\text{Volume of the cube}}$

$$=\frac{3}{\frac{1}{8} }$

$=3\times8$

$=24$

Number of cubes = 24

Hence 24 cubes can filled up the prism.

Point (2, -4) is reflected across the x-axis. What are<br> the coordinates of its image?

Zina [86]

The coordinates of the image of point (2 , -4) after reflection across

the x-axis is (2 , 4)

Step-by-step explanation:

Let us revise the reflection of a point

1. If point (x , y) reflected across the x-axis, then its image is (x , -y)

2. If point (x , y) reflected across the y-axis, then its image is (-x , y)

3. If point (x , y) reflected across the line y = x, then its image is (y , x)

4. If point (x , y) reflected across the line y = -x, then its image is (-y , -x)

∵ Point (2, -4) is reflected across the x-axis

∵ Point (x , y) reflected across the x-axis, then its image is (x , -y)

- Chang the sign of the y-coordinate of the point to find its image

∵ The y-coordinate of the point is -4

∴ The y-coordinate of the image is 4

∴ The image of the point (2 , -4) is (2 , 4) after reflection across the

x-axis

The coordinates of the image of point (2 , -4) after reflection across

the x-axis is (2 , 4)

Find the mean, mode and median of 3, 4, 5, 4, 6, 4, 7.

Luda [366]

Mode = is the number with the highest frequency so the answer is 4.
Mean = the average so the answer is 3+4+5+4+6+4+7=33 so 33/7=4.7 (rounded to the nearest one decimal).
Median = the middle number, so the answer is 4.
