The base perimeter of a triangular prism is 36cm and lateral surface area is

Phoenix [80]

(a)

Lateral surface area of prism =720cm²(Given) Perimeter x height = 720

36 x height = 720

$∴ Height\: of\: prism = \frac{720}{36} = 20\\(b) Total \:surface\: area\: of\: prism = 2 x \:base\: area\: + L.\: S.\: A\: of \:prism \\ = \frac{2 \times \sqrt{3} }{4} \times( {12}^{2} ) + 720 \\ = (72 \sqrt{3} + 720) {cm}^{2} \\ = (72 \times 1.732 + 720) {cm}^{2} \\ = 844.704 \frac{}{} {cm}^{2}$

Lanya's house is located at (2 2/3, 7 1/3) on a map. The store where she works is located at (-1 1/3, 7 1/3). what is the distan

notka56 [123]

Answer:

Option A: 4 units is the correct answer.

Step-by-step explanation:

Given that:

Layana's house is located at ( $2\frac{2}{3}, 7\frac{1}{3}$ )

Store is located at ( $-1\frac{1}{3},7\frac{1}3}$ )

We can find distance between two points by using distance formula.

S = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2$

The points can also be written as;

House (8/3, 22/3)

Store (-4/3, 22/3)

Putting values in the formula.

S = $\sqrt{\frac{8}{3}-(-\frac{4}{3}))^2+(\frac{22}{3}-\frac{22}{3})^2$

S = $\sqrt(\frac{8}{3}+\frac{4}{3}+0$

S = $\sqrt{(\frac{8+4}{3})^2$

S = $\sqrt{(\frac{12}{4})^2$

S = $\sqrt{(4)^2$

S = 4 units

Hence,

Option A: 4 units is the correct answer.

A robot can complete 8 tasks in 3/5

vekshin1

Since 3/5 of an hour is 36 minutes and the robot can complete 8 tasks in 36 minutes. The remaining minutes are 24 and in 24 minutes the robot can do about 5 tasks so add 5 and 8 to get about 13 tasks in an hour.

Explanation: Just divide 36 by 24 to get 1.5 and divide 8 by 1.5 to get about 5. Then add 8 + 5 to get 13 the final result. So it’s 13 tasks. Sorry if I got it wrong.
