VARVARA [1.3K]3 years ago

6 0

Answer:

Step-by-step explanation:

Step 1 : List the prime factors of each number

8 : 2 x 2 x 2

12 : 2 x 2 x 3

Step 2: Identify the numbers that are common between the two sets of prime factors:

in our case, we see that only "2 x 2" shows up in both lines, hence 2 x 2 is the GCF.

2 x 2 = 4

Hence the GCF is 4

Given : $a=20$

To Find : the value of expression 5a.

Solution :

We are given the value of 'a' i.e. a=20

Now to find the value of given expression 5a

⇒ $5a$

put a = 20 in the equation

⇒ $5*20$

⇒ $100$

⇒ $5a = 100$

Thus , The value of expression 5a when a = 20 is 100

An architect is designing an office building with n floors that will have an FM radio antenna 15.85 m tall on its roof. Each flo

sveticcg [70]

Answer:

h=3.9x+15.85 meters

Step-by-step explanation:

Let's say that the height of the floor just before the roof to the highest point of the roof is also 3.9 m, perhaps, we have an almost flat roof

Since the FM radio antenna is fixed on top of roof, the total height is that of previous floors and the antenna

Taking the building to have x number of floors with each floor having 3.9 m height, the function of height will be

h=3.9x + 15.85 meters

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.
