Answer:

x = 13.5 units

Step-by-step explanation:

Segment drawn to join the two sides of the triangle is parallel to third side of the triangle.

Therefore, by basic proportionality theorem:

$\frac{12}{27} = \frac{6}{x} \\ \\ x = \frac{27 \times 6}{12} \\ \\ \huge \red{ \boxed{x = 13.5 \: units}}$

Answer:

TW = ST

Step-by-step explanation:

RS = RW (Given)

RT = RT (reflexive property)

This makes ∆RST congruent to ∆RWT based on the reflexive property of congruence.

Therefore, the third corresponding sides, TW and ST would be congruent to each other.

Thus:

TW = ST

Find the surface area of the cylinder give your answer in terms of pi. The radius is 4mm and the height is 5mm

Komok [63]

The surface area of a cylinder is the area of the bases plus the area of the side, or SA = 2*A₁ + A₂

Since the area of a circle is $\pi r^{2}$ ,
SA = 2*( $\pi r^{2}$ ) + A₂

Since the area of the side is height * the circumference of the circle or A₂ = h * $2 \pi r$ , then SA must be;

SA = $2* \pi (r ^{2} )+h*2 \pi r$
SA = $2* \pi (4 ^{2} )+5*2 \pi (4)$
SA = $32* \pi+80 \pi$
SA ≈ <span>351.858377202</span>

Alan multiplies a 4-digit number by 36. How can you tell the

mafiozo [28]

The number of partial products Alan will have when he multiplies a 4-digit number by 36 is; 8 partial products.

First, we must establish that a 4-digit number will have 4 place values namely;

Thousands
Hundreds
Tens
Ones.

And since, 36 has 2 place values;

We can conclude that the number of partial products that Alan wil have is; 2× 4 = 8.
