A scale for a scale drawing is 10cm:1mm. which is larger the actual object or drawing explain

Answers

If I'm understanding your question, the drawing is 10cm and for every 10cm, the drawing is etched 1mm. This means that no matter how big the drawing gets, the actual object will always be bigger since it's 10cm larger always than the drawing. Hope this helped!

B) 1/4

C) 12/17

D) 8/9

Answers

Answer: The correct option is (D) $(8)/(9).$

Step-by-step explanation: Given that $(3)/(4)$ of Melissa's friends babysit for extra money and $(2)/(3)$ of her friends babysit and pet sit.

We are to find the fraction of her friends those who babysits also pet sits.

Total fraction of Melissa's friends is given by

$F=(3)/(4).$

Therefore, the fraction of her friends those who babysits also pet sits is given by

$f=((2)/(3))/((3)/(4))=(2)/(3)*(4)/(3)=(8)/(9).$

Thus, the required fraction is $(8)/(9).$

Option (D) is CORRECT.

Brent's pick-up truck can carry 1/5 ton. Nina's pick-up truck can carry 500 pounds. Whose pick-up truck carry's more weight. ExplainDon't know how to Explain

Answers

Answer: Nina's pick up truck carry's more weight.

Step-by-step explanation:

We know that 1 ton = 2,000 pounds

Given: Brent's truck can carry the maximum weight= $(1)/(5)$ ton

In pounds, The maximum load can be carried by Brent's truck = $(1)/(5)*2000=400\text{ pounds}$

Nina's truck can carry the maximum weight = 500 pounds

Clearly, $500\text{ pounds} > \text{ 400 pounds}$

Therefore, Nina's pick up truck carry's more weight.

Nina's truck bc a whole ton is 2,000 pounds so 1/5 of 2,000 pounds is 400 pounds and nina has 500 pounds so she has 100 more pounds than brent
