The drama club at NAMS sells hot chocolate and coffee at the high school football games. At the last game, they had sales of $200. They need to keep track of how many of each type drink was sold so that they can make predictions for future sales. Monica knows that they used 275 cups that night. If the hot chocolate sells for 75 cents and coffee sells for 50 cents, how much of each type of drink were sold?

Answers

Answer:

Coffee = 25

Hot Chocolate = 250

Step-by-step explanation:

Coffee: c

Hot Chocolate: h

0.75h + 0.50c = 200

h + c = 275

h + c = 275

h = 275 - c

0.75h + 0.50c = 200

0.75(275 - c) + 0.5c = 200

206.25 - 0.75c + 0.5c = 200

-0.25c = -6.25

-0.25c/-0.25 = -6.25/-0.25

c = 25

0.75h + 0.5(25) = 200

0.75h + 12.5 = 200

0.75h = 200 - 12.5

0.75h = 187.5

0.75h/0.75 = 187.5

h = 250

Check: c = 25; h = 250

0.75h + 0.50c = 200

h + c = 275

0.75(250) + 0.5(25) = 200

187.5 + 12.5 = 200

200 = 200

h + c = 275

250 + 25 = 275

275 = 275

The drama club sold 250 hot chocolates and 25 coffee drinks.

Equation

Equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the number of hot chocolate and y represent the number of coffee. From the question the equation are:

x + y = 275   (1)0.75x + 0.5y = 200 (2)

From both equations:

x = 250, y = 25

The drama club sold 250 hot chocolates and 25 coffee drinks.

economics?
a) 30% b) 90%
c) 70% d) None of these

Solution with som explanation

Answers

Answer:

a) 30%

Step-by-step explanation:

50% of the students were taking statistics subject, 30% economics and 10% both the subjects.

The probability a student takes only statistics = 50% - 10% = 40%

The probability a student takes only economics = 30% - 10% = 20%

The probability a student was taking neither statistics nor  economics = 100% - (40% + 20% + 10%)

The probability a student was taking neither statistics nor  economics = 30%

Answers

Answer:

Step-by-step explanation:

Given:

Length = 24 cm

Width = 8 cm

Height = 6 cm

Required:

Diagonal of the box

SOLUTION:

Using the pythagorean theorem, [tex] a^2 + b^2 + c^2 = d^2 [/tex], where,

a, b and c are the dimensions of the box, and d is the length of the diagonal.

Plug in the value into the formula

[tex] 24^2 + 8^2 + 6^2 = d^2 [/tex]

[tex] 676 = d^2 [/tex]

[tex] \sqrt{676} = \sqrt{d^2} [/tex]

[tex] 26 = d [/tex]

A rabbit moves n times as fast as a squirrel . A fox moves m times as fast as a rabbit . The fox moves how many times as fast as the squirrel?

Answers

Answer:

the fox moves mn times as fast as the squirrel

Step-by-step explanation:

the easiest way to do problems like this is by using hypothetical values that make sense (it's best to avoid 0, 1, and 2)

we'll say that n = 3 and m = 4

so if the squirrel moves at s pace, then the rabbit moves at ns, or 3s.

if the fox moves at m (4) times the rabbit's pace (3s), then it moves at 4(3s)

then just switch out the numbers for their variables, giving you m(ns)

remember that s simply represents the squirrel's pace, we cannot replace it with a number in this case, so switch it with the idea/value it represents

and there you go, mn times the squirrel's pace

A kite of area 40 m squarehas one diagonal 2 m longer than the other. Find the length of the diagonal

Answers

Answer:

Length of diagonal 1: 8 metersLength of diagonal 2: 10 meters

Step-by-step explanation:

Let d1 be the first diagonal and d2 be the second diagonal.

Given

Area = 40 square meters

And one diagonal is 2 meter longer than other

[tex]d_2 = d_1+2[/tex]

The formula for area of kite is;

[tex]Area = \frac{1}{2} * d_1 * d_2[/tex]

Putting the known values

[tex]40 = \frac{1}{2} * d_1 * (d_1+2)\\80 = (d_1)^2+2d_1\\d_1^2 +2d_1-80 = 0\\[/tex]

The expression is a quadratic polynomial

Factorizing

[tex]d_1^2 + 10d_1-8d_1-80 = 0\\d_1(d_1+10)-8(d_1+10) = 0\\(d_1+10)(d_1-8) = 0\\d_1 + 10 = 0\\d_1 = -10\\d_1-8 = 0\\d_1 = 8[/tex]

As the value of length cannot be negative so discarding the negative value

[tex]d_1 = 8d_2 = d_1+2 = 8+2 =10[/tex]

Hence,

Length of diagonal 1: 8 metersLength of diagonal 2: 10 meters
