Teesha is in French Club:
=> 10 freshman
=>12 sophomores
=>15 juniors
=> 30 seniors in the club.
The advisor is going to randomly choose one ofthe members of the club to be a guide for an important visitor.
Out of 4 groups, only 1 will be selected.
=> 10 freshman + 12 sophomores +15 juniors + 30 seniors = 67 students
=> 67 / 4 = 16.75
OR close to
=> 15/67

Kim bought a poster that cost $8.95 and some color pencils. The total cost was $21.35. How much did the colored pencils cost?

Answers

Total amount of the colored pencils is given by the equation A = $ 12.40

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the amount of the color pencils be represented as A

Now , the equation will be

The total purchase amount by Kim = $ 21.35

The amount for the poster = $ 8.95

So ,

The amount for the color pencils A = total purchase amount by Kim - amount for the poster

Substituting the values in the equation , we get

The amount for the color pencils A = $ 21.35 - $ 8.95

On simplifying the equation , we get

The amount for the color pencils A = $ 12.40

Therefore , the value of A is $ 12.40

Hence , the amount for the color pencils is $ 12.40

Two spherical chocolates are filled with a cream filling. The space inside one chocolate has a radius of 3 cm, and the other has a radius of 4.5 cm.How much more cream filling is in the larger chocolate than in the smaller chocolate? Use 3.14 to approximate pi and enter your answer to two decimal places.

Answers

so first find the volume of each then subtract

volume=4/3 times pi times r^3

rasius of smaller=3
4/3 times pi times 3^3
4/3 times pi timer 27
4/3 times 27 times pi
36 times pi
aprox pi=3.14
36 times 3.14
113.04=smaller

volume of smaller
4/3 times 3.14 times 4.5^3
4/3 times 3.14 times 91.125
381.51

subtract
381.51-113.04=268.47

the volume is 268..47 cm^3
