Fellow person with an easy question here :)) Travis made a scale drawing of a horse fly. If the scale is 4 mm= 1cm, then what is the actual wingspan of the horsefly?

A: 6.4 cm

B: 5.0 cm

C:5.5 cm

D: 4.4 cm

Answers

Answer 1

Answer:

The actual wingspan of fly is 5.5cm

Step-by-step explanation:

Given,

Scale of drawing;

4mm = 1cm

Ratio of mm to cm = 4:1

Wingspan of fly in drawing = 22mm

Let,

x be the actual wingspan.

Ratio of mm to cm = 22:x

Using proportion;

Ratio of mm to cm :: Ratio of mm to cm

$4:1::22:x\n$

Product of extreme = Product of mean

$4*x=22*1\n4x=22$

Dividing both sides by 4

$(4x)/(4)=(22)/(4)\nx=5.5$

The actual wingspan of fly is 5.5cm

daniel spends 3/7 of his money on rent and 4/9 of his money on food . Does he soend more money on food or drinks. Explain.

Answers

We need to find the common denominator which is 63.

3 x 9 = 27
7 x 9 = 63

3/7 = 27/63

4 x 7 = 28
9 x 7 = 63

4/9 = 28/63

So Daniel spent more money on food.
