Answer:

Step-by-step explanation:

In elementary algebra, the binomial theorem (or binomial expansion) describes the algebraic expansion of powers of a binomial. According to the theorem, it is possible to expand the polynomial (x + y) into a sum involving terms of the form a x y, where the exponents b and c are nonnegative integers with b + c = n, and the coefficient a of each term is a specific positive integer depending on n and b. For example (for n = 4).

7over10 subtract 5over12 in simplest form

Andrews [41]

Answer: $=\frac{17}{60}\quad \left(\mathrm{Decimal:\quad }\:0.28333\dots \right)$

Step-by-step explanation:

$\left(\frac{7}{10}\right)-\left(\frac{5}{12}\right)$

$=\frac{7}{10}-\frac{5}{12}$

$=\frac{42}{60}-\frac{25}{60}$

$=\frac{42-25}{60}$

$=\frac{17}{60}$

If y varies directly as x and z, and Y=40 when x =5 andz = 4, find y when x=2 and z = 1

Yuki888 [10]

Answer: When x=2 and z = 1, then the value of y =4.

Step-by-step explanation:

Given: y varies directly as x and z i.e. $y\ \alpha \ xz$

$y=k(xz)$ (i) , where k is the proportionality constant.

Put Y=40 ,x =5 and z = 4, then we get

$40=k(5\times4)\\\\\Rightarrow\ k=\dfrac{40}{20}\\\\\Rightarrow\ k=2$

Required equation: $y=2(xz)$ [Put value of k in (i)]

Now put x=2 and z = 1, then we get

$y=2(2\times1)=2(2)=4\\\\\Rightarrow\ y=4$

Hence, when x=2 and z = 1, then the value of y =4.

Lydia bought a shirt at 20% off its retail price of $40. She paid 5% tax on the price after the discount. How much did Lydia pay

lys-0071 [83]

$33.60. 20% of 40 is 8. 40 minus 8 is 32. 5% of 32 is 1.60, with a sum of 33.60, the total for the shirt.

A clock tower has a circular clock face with a circumference of 48π feet. What is the radius of the clock face ?

KatRina [158]

Answer:

r = 24 ft

Step-by-step explanation:

Circumference is given by

C = 2 * pi *r

We know that C = 48 pi

48 pi = 2 * pi * r

Divide each side by pi

48 pi /pi= 2 * pi * r/pi

48 = 2 r

Divide each side by 2

48/2 = 2r/2

24 = r
