Answer:

64 g

Step-by-step explanation:

Lets gather the Info

Amount needed = 161 g

Amount given = 97 g

Lets form an equation:

161 - 97 = x

x in this case is the number of grams needed to fulfill the amount needed.

161 - 97 = 64 g

He needs 64 g of cheese.

the birth rate in namibia is 35 babies to every 1000 people. In 2001, the country had a population of about 1,800,000 people. ho

mr_godi [17]

Hey there!

Let's work this problem out together.

Our ratio is 35:1000, or 35/1000.

Let's try solving this in two ways.

First, we can look at our ratio 35/1000, which is equal to 0.035.

35 is 0.035 of 1000.

Therefore, to find the amount of babies, we can multiply this connecting number by the number of people.

1,800,000(0.035)=63,000

Therefore, there would be 63,000 babies.

---------------------------------------------------------------

We can also solve this as a proportion.

$\frac{babies}{people} =\frac{35}{1000} =\frac{b}{1,800,000}$

To solve, we can cross multiply and solve for b.

1,000b=63,000,000

We divide both sides by 1,000/

b=63,000

Therefore, there are 63,000 babies.

I hope this helps!

MARKING AS BRAINLIEST!! Starr if given functions are inverse)!

kifflom [539]

Answer: They are inverses of each other.

Explanation:

f(x) = -x+5

f(g(x)) = -(g(x)) + 5

f(g(x)) = -(-x+5) + 5

f(g(x)) = x - 5 + 5

f(g(x)) = x

The steps to show that g(f(x)) = x are identical to what is shown above. This is because both f(x) and g(x) are the same.

Since f(g(x)) = x and g(f(x)) = x are true, this means the functions are inverses of each other.

Find the value of root 121 + 3 over root 125

NemiM [27]

Answer:

$\mathrm{Decimal:\quad }\:1.25219\\\frac{14\sqrt{5}}{25}$

Step-by-step explanation:

$\frac{\sqrt{121}+3}{\sqrt{125}}\\\sqrt{125}=5\sqrt{5}\\=\frac{\sqrt{121}+3}{5\sqrt{5}}\\\sqrt{121}=11\\=\frac{11+3}{5\sqrt{5}}\\\mathrm{Add\:the\:numbers:}\:11+3=14\\=\frac{14}{5\sqrt{5}}\\\mathrm{Rationalize\:}\frac{14}{5\sqrt{5}}:\quad \frac{14\sqrt{5}}{25}\\=\frac{14\sqrt{5}}{25}$

A coin is flipped twice. What is the probability that the coin will land on tails on the first flip and will land on tails again

bixtya [17]

Answer:

1/4=0.25=25%

Step-by-step explanation:

A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.

1/2=50

1/4=25

0.25 x 100= 25%

hope that helps
