What number has a 9 with a value ten times as many as the 9 in 39,154
Tomtit [17]

Answer:

Any number with 9 in the ten-thousands place. 90,000 is one such number.

Step-by-step explanation:

The 9 in 39,154 is in the thousands place. Its value is 9,000. In order for the 9 in a number to have a value 10 times that, or 90,000, the 9 must be in the ten-thousands place.

There are an infinite number of such numbers. We suspect you have a list you are to choose from. Pick the number with 9 where it is in the number 90,000.

Punctele A,B si C sunt coliniare in aceasta ordine.Aflati lungimea segmentului:a)AB,daca AC=20cm,BC=0,12dm
Strike441 [17]

Answer:

The length of the segment AB is 18.8 cm or 1.88 dm

Step-by-step explanation:

<u><em>The question in English is</em></u>

Points A, B and C are collinear in this order. Find the length of the segment: a) AB, if AC = 20 cm, BC = 0.12 dm

we have that

AC=AB+BC ----> by Addition segment postulate

substitute the given values in centimeters

Remember that

1\ dm=10\ cm

so

0.12\ dm=0.12(10)=1.2\ cm

20=AB+1.2

solve for AB

AB=20-1.2\\AB=18.8\ cm

Convert to dm

18.8\ cm=18.8/10=1.88\ dm

therefore

The length of the segment AB is 18.8 cm or 1.88 dm
