Twelve plus eight is 20. 12/20 equals 60/100. Percents are out of 100, so 60%

The admission fee at a small fair is $2.00 for children and $4.00 for adults on a certain day 30 people enter the fair and $100

Troyanec [42]

Answer:

20 adults and 10 children

Step-by-step explanation:

We need to find the total amount of adults and children for 30 total people (adults + children) and only 100$ for them. 30 adults is 120$. We need to take off double the amount of money that would bring it to 100$ because the cost for each child is half of an adult. That way, we have 80$ of adults, and when we fill in the rest with children, we get to 100$ total and 30 total people.

10 A solid metallic cylinder of radius 14 cm and

vodomira [7]

Answer:

72 spheres are formed

Step-by-step explanation:

We start by calculating the volume of the metallic cylinder

Mathematically, we have this as;

V = pi * r^2 * h

V = pi * 21 * 14^2

V = 4116 π cm^3

The volume of each small sphere is;

V = 4/3 * pi * r^3

= 4/3 * π * 7/2^3 = 57.167 π cm^3

To get the number of small spheres, we simply divide the volumes

That will be 4116 pi / 57.167 pi = 72

Find the distance between the points E(3, 7) and F(6, 5). The exact distance between the two points is .

S_A_V [24]

Answer:

$\sqrt{13}$

Step-by-step explanation:

The trick here is to know the distance formula (a formula that helps you find the distance between two points).

Distance formula: distance = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

But now that we know this, we can simply plug in our values and solve!

$\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\sqrt{(6-3)^2+(5-7)^2}\\\sqrt{(3)^2+(-2)^2}\\\sqrt{9+4}\\\sqrt{13}$

Now we can tell from our answer that the distance between both points is $\sqrt{13}$

In a store, 1 can of soup costs $1.80. The store also sells a pack 6 cans of soup. A customer who buys 1 pack saves 15% compared

Likurg_2 [28]

Answer:

$\$1.62$

Step-by-step explanation:

Let

x-----> the cost of one pack of 6 cans of soup

step 1

Find the cost of 6 cans of soup

$6(1.80)=\$10.8$

step 2

Find the cost of one pack of 6 cans of soup

$100\%-15\%=85\%=85/100=0.85$

$x=0.85(\$10.8)=\$9.18$

step 3

Find the money saved

$\$10.8-\$9.18=\$1.62$
