If f = price of filing cabinet and c = price of cupboard we can make up the equation

2f + 4c =800

we also know that f = 3c, so can substitute that into equation

2(3c) +4c = 800

6c + 4c = 800

10c = 800

<u>c = 80</u>

<u>f = 240</u>

The 3rd term of (a-b)4 is
fgiga [73]

The third term of the expansion is 6a^2b^2

<h3>How to determine the third term of the expansion?</h3>

The binomial term is given as

(a - b)^4

The r-th term of the expansion is calculated using

r-th term = C(n, r - 1) * x^(n - r + 1) * y^(r - 1)

So, we have

3rd term = C(4, 3 - 1) * (a)^(4 - 3 + 1) * (-b)^(3-1)

Evaluate the sum and the difference

3rd term = C(4, 2) * (a)^2 * (-b)^2

Evaluate the exponents

3rd term = C(4, 2) * a^2b^2

Evaluate the combination expression

3rd term = 6 * a^2b^2

Evaluate the product

3rd term = 6a^2b^2

Hence, the third term of the expansion is 6a^2b^2

An ice cream cone is 5" deep and 2" in top diameter. One scoop of vanilla ice cream, 2" in diameter, is placed on the cone. If t
Ratling [72]
If the total volume of the ice cream exceeds the internal volume of the cone, then it will overflow.

Volume of icecream = 4/3 * pi * r^3 = 4/3*pi*(1)^3 = 4.189 cu. in.Volume of cone = 1/3 * pi * r^2 * h = 1/3*pi*(1)^2*5 = 5.236 cu. in.

Since Volume of cone > Volume of icecream, the cone will not overflow.

Evaluate 5c+cd5c+cd5, c, plus, c, d when c=\dfrac15c=
zepelin [54]

Answer:

4

Step-by-step explanation:

The function is given as 5c+cd, c=1/5 and d=15d.

We evaluate by substituting the given values of c and d in the function:

5c+cd, c=1/5 \ \ \, d=15\\\\=5\times \frac{1}{5}+\frac{1}{5}\times 15

=1++3\\\\=4

After substituting, we find the function's equivalent as 4.

Hence, the value of the function is 4
