Mathematics
1 answer:
lora16 [44]3 years ago
6 0

Answer:

BE = 72 cm

Step-by-step explanation:

\frac{AB}{BC} = \frac{BE}{CD}        (BPT Theorem)

\frac{20}{5} = \frac{BE}{18} \\

⇒ 4 = \frac{BE}{18}

⇒BE = 18 × 4

∴ BE = 72 cm

The product of any two numbers is composite ( true/false) and why?
Reptile [31]
<u><em>FALSE.</em></u><em></em> 
A composite number is the opposite of a prime number. This is false because of the possibility of the following scenario:
The two numbers are 1 and a prime number.
This is because <em>one multiplied by any number is that number.</em> A prime number cannot become a composite number just because it is being multiplied by one. For example:
1 x 7 = 7 (prime)

Find the x-value for point C such that AC and BC from a 2:3 ratio.
Galina-37 [17]

Given:

Point C divides AB such that AC:BC=2:3.

To find:

The x-value for point C.

Solution:

Section formula: If a point divide a line segment in m:n, then

Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)

Form the given graph it is clear that the endpoints of the line segment AB are A(-3,5) and B(3,0).

Point C divides AB such that AC:BC=2:3. Using section formula, the coordinates of point C are

C=\left(\dfrac{2(3)+3(-3)}{2+3},\dfrac{2(0)+3(5)}{2+3}\right)

C=\left(\dfrac{6-9}{5},\dfrac{0+15}{5}\right)

C=\left(\dfrac{-3}{5},\dfrac{15}{5}\right)

C=\left(-0.6,3\right)

The x-value of C is -0.6.

Therefore, the correct option is B.
