Answer:

3 of 10 grid squares making up the whole will be colored.

Step-by-step explanation:

1/10 is one of ten equal parts. 3/10 is three of those ten equal parts. Essentially, the fraction 3/10 means "three out of ten".

_____

If the whole is divided into more than 10 parts, 3/10 will be 3 out of every 10. So if there are 20 parts, for example (2 tens), the 3/10 will be 6 of those parts (3 of each of the two tens).

Write an exponential function to represent both of these

Hunter-Best [27]

Answer:

1. $y = 2(3)^x \ or \ y = 6^x$

2. $y = 10(2)^x \ or \ y = 20^x$

Step-by-step explanation:

1. Solution for 1st part.

Given:

Ben shared his post with 2 friends

Each of those friends shares with 3 more every day.

the number of shares triples every day.

From the data given above, we can make the following:

$N(0) = 2 \times 3^0 = 2\\N(1) = 2 \times 3^1 = 6\\N(2) = 2 \times 3^2 = 18$

An exponential function is represented by:

$y = ab^x$

where a is the initial value and b is the growth rate.

The exponential function for this case would be:

$y = 2(3)^x \ or \ y = 6^x$

2. Solution for part 2.

Given:

Carter shared his post with 10 friends.

each share with only 2 people each day.

From the data given above, we can make the following:

$N(0) = 10 \times 2^0 = 10\\N(1) = 10 \times 2^1 = 20$

An exponential function is represented by:

$y = ab^x$

where a is the initial value and b is the growth rate.

The exponential function for this case would be:

$y = 10(2)^x \ or \ y = 20^x$

(1) a) 5270 cl= ? dal

Ivanshal [37]

Answer:

Check below

Step-by-step explanation:

1) These metric volume units can be easily converted by dividing or multiplying by 10 and its multiple. Like this: each step up on the ladder multiply by 10. Each step down divide by 10

$a)5270 \:cl=527\:dl\\b)kl=5.3 \times 10=530 hl\\c)58000ml=5.8 dal =(\frac{58000}{10000})\\d)0.39 dal=3.9 l\\e)7.8 dal=780 dl\\f)57.2 ml=5.72 cl$ .

2) When it comes to area, the "ladder scheme" remains valid but now we'll multiply or divide by

$10^3$

Bear in mind these useful relations:

$1litre =\frac{1}{10^3}m^{3}$

$1 cm^{3} =1 ml$

$a) 3.7 l=3700 cm^{3}\\b)29.6 dm^{3}\\29.6 dm^{3} \rightarrow 29.6\times10^{3} cm^3=29.6\times10^{3} ml = 29.6\times10^{2} cl \:or\:2960 cl\\c)8.1l=8100 cm^{3}\\d)5l=\frac{5}{10^{-3}} m^{3}\\e)5.2 cl=52ml=52 cm^{3}=52\times10^{3}=52000 \:mm^{3}\\f)375 ml=375 cm^{3}\\g) 1300 cm^{3}=1300 ml=13 dl\\h) 8.6 ml= 8.6 cm^{3}\times\: 10^{3}=8600 mm^{3}\\i) 51.8\times 10^{11} l \rightarrow 51.8\times 10^{-11}km^{3}$
