Find the area of the triangle

Helga [31]

Answer:

The answer is

$\huge \boxed{54 \: \: {units}^{2} }$

Step-by-step explanation:

Area of a triangle is given by

$A = \frac{1}{2} \times base \times height \\$

From the question

base = 18

height = 6

So we have

$A = \frac{1}{2} \times 18 \times 6 \\ = 9 \times 6 \\ = 54 \: \: \: \: \:$

We have the final answer as

Jones assembles 200 relays in the same time that Smith assembles 180. When Jones has completed 300 relays, how many will Smith h

Finger [1]

Answer:

270

Step-by-step explanation:

Jones turns out 200 relays to Smith's 180. You set up that basic ratio and make a proportion out of it.

S/J = 180/200

Now you make your proportion

S/J = x/300

But the 2 ratios much remain the same.

180/200 = x / 300 Multiply both sides by 300

180*300/200 = x Multiply the numerator together.

54000/200 = x Do the division

270 = x

Smith will have turned out 270 relays.
