The actual length of side t is 0.045 cm. Use the scale drawing to find the actual side length of w.
Nataly_w [17]

Answer:

Actual length of w is 0.075 units.

Step-by-step explanation:

Given the actual length of side t is 0.045 cm.

we have to use the scale drawing to find the actual side length of w.

As given the actual length of t is 0.045 cm.

Hence, we can find the scale factor using the lengths of t i.e actual length and after scale drawing by dividing.

Scale factor is \frac{0.9}{0.045}=20

Hence, we get the scale factor.

Now, scale factor=\frac{\text{length in figure}}{\text{actual length}}

⇒ 20=\frac{1.5}{\text{actual length}}

⇒ Actual length of w is \frac{1.5}{20}=0.075units

Option B is correct.

43×15= what is the correct answer
mario62 [17]
43 × 15 = 645.

First, set up the long multiplication.
Second, calculate 3 × 5, which is 15. Since 15 is two-digit, carry the first digit 1 to the next column.
Third, calculate 4 × 5 which is 20. Since 21 is two-digit, carry the first digit 2 to the next column.
Fourth, bring down the carry digit of 2. 
Fifth, calculate 3 × 1, which is 3.
Sixth, calculate 4 × 1, which is 4.
Seventh, calculate 215 + 430, which is 645.
Eighth, therefore, 43 × 15 = 645.

Or.. an easier way is to use a calculator. They always come in handy when doing multiplication.

<u>ANSWER: </u>

x − intercept is (\frac{8}{3}, 0) , y − intercept is (0,8).

<u>SOLUTION: </u>

Given, linear equation is y = 3x – 8 --eqn (1)

We need to find x – intercept and y – intercept i.e. where the line meets x – axis and y – axis

Now, let us find x – intercept. So put y = 0 in eqn (1)

0 = 3x – 8

3x = 8

x = \frac{8}{3}

So, point where given line meets x – axis is (\frac{8}{3} ,0)

Now, let us find y – intercept. So put x = 0 in (1)

y = 3(0) – 8

y = 8

So, point where given line meets y – axis is (0,8).

Hence, x − intercept is (\frac{8}{3} ,0) , y − intercept is (0,8).
