Simplify: (–8) • (6) – (5) • (–2)

horrorfan [7]

(–8) • (6) – (5) • (–2)

= (-8*6)-(5*-2)

= (-48)-(-10)

= -48+10

= -38

(–4) • (9) – (5) • (–2)

= (-4*9)-(5*-2)

= (-36)-(-10)

= -36+10

= -26

Evaluate 3(a – 4b) when a = –2 and b = 5.

= 3[-2 - 4(5)]

= 3[-2 -20]

= 3(-22)

= -66

Evaluate 4(a – 3b) when a = –4 and b = 6.

= 4[-4 - 3(6)]

= 4[-4 -18]

= 4(-22)

= -88

Evaluate 5(a – 2b) when a = –3 and b = 5.

= 5[-3 - 2(5)]

= 5(-3 - 10)

= 5(-13)

= -65

The diameter of a quarter is 24.26 mm and the diameter of a nickel is 21.21 mm. How much bigger is the distance around a quarter

olga55 [171]

Answer:

9.577 mm.

Step-by-step explanation:

We have been given that the diameter of a quarter is 24.26 mm and the diameter of a nickel is 21.21 mm.

Let us find the circumference of quarter and nickel using circumference of circle formula.

$\text{Circumference of circle}=2\pi r$ , where r represents radius of the circle.

Since we know that diameter of circle is 2 times its radius, so let us find radius of quarter and nickel by dividing their diameter by 2.

$\text{Radius of quarter}=\frac{24.26}{2}$

$\text{Radius of quarter}=12.13$

$\text{Radius of nickel}=\frac{21.21}{2}$

$\text{Radius of nickel}=10.605$

$\text{Circumference of quarter}=2\times 3.14\times 12.13$

$\text{Circumference of quarter}=76.1764$

Therefore, circumference of quarter is 76.1764 mm.

Let us find circumference of nickel.

$\text{Circumference of nickel}=2\times 3.14\times 10.605$

$\text{Circumference of nickel}=66.5994$

Let us subtract circumference of nickel from circumference of quarter.

$\text{The difference between distance around quarter and nickel}=76.1764-66.5994$

$\text{The difference between distance around quarter and nickel}=9.577$

Therefore, the distance around a quarter is 9.577 millimeters bigger than a nickel.
