6.	What is the distance between -a and 0
Answer» Answer DISTANCE is $\|-a\|=\begin{cases} &-a (a\geq 0) \\ &a (a$ . Solution A distance between two lines is a absolute value. Because distance is a non-negative value. After moving the distance, we end up in a greater number. Total Cases $-a$ can be EITHER positive, 0, or negative. CASE 1. $-a$ $-a+\mathrm{Distance}=0$ $\therefore\mathrm{Distance}=a$ Case 2. $-a=0$ $\therefore \mathrm{Distance}=0$ Case 3. $-a>0$ $0+\mathrm{Distance}=-a$ $\therefore\mathrm{Distance}=-a$ It's all positive value, so it can be written as $\|-a\|$ . More information On the number line, adding the numbers is moving to the right. 0 is called the origin. The absolute value is the value WITHOUT a negative sign. Verification Distance between -1 and 0 is 1, or $\|1\|=1$ (True). Distance between 1 and 0 is 1, or $\|-1\|=1$ (True).

What is the distance between -a and 0

Answer»

Answer

DISTANCE is $|-a|=\begin{cases} &-a (a\geq 0) \\ &a (a$ .

Solution

A distance between two lines is a absolute value.

Because distance is a non-negative value.

After moving the distance, we end up in a greater number.

Total Cases

$-a$ can be EITHER positive, 0, or negative.

CASE 1. $-a$

$-a+\mathrm{Distance}=0$

$\therefore\mathrm{Distance}=a$

Case 2. $-a=0$

$\therefore \mathrm{Distance}=0$

Case 3. $-a>0$

$0+\mathrm{Distance}=-a$

$\therefore\mathrm{Distance}=-a$

It's all positive value, so it can be written as $|-a|$ .

More information

On the number line, adding the numbers is moving to the right.

0 is called the origin.

The absolute value is the value WITHOUT a negative sign.

Verification

Distance between -1 and 0 is 1, or $|1|=1$ (True).

Distance between 1 and 0 is 1, or $|-1|=1$ (True).

Screenshot 2021-03-...15.45 PM.png

Answer»

Answer:

$\boxed{d=8}$

Step-by-step explanation:

First: note that 3/9 becomes 1/3 we can simplify the fraction on the RIGHT hand side:

$\frac{16}{<klux>6</klux>} = \frac{3d}{9} \implies \frac{16}{6} = \frac{d}{3}$

SECOND: Multiply both SIDES by (6*3), so that the denominator will cancel: $(6*3) \cdot \frac{16}{6} = \frac{d}{3} \cdot (6*3)$$$\\$$$\Rightarrow 3*16 = 6*d$$

Third: 3 * 16 = 48, Use the division rules of algebra to solve for d

$48= 6*d \implies d = \frac{48}{6} = 8$

Therefore, $\boxed{d=8}$

Find the area of circle with the given diameter 8 cm 20 cm

Answer»

Answer:

(i) 50.24 cm²

(ii) 314 cm²

Step-by-step explanation:

(i) Diameter = 8 cm

Radius r = 4

Area = πr² = 3.14 × 4² = 3.14 × 16 = 50.24 cm²

(ii) Diameter = 20 cm

Radius r = 10

Area = πr² = 3.14 × 10² = 3.14 × 100 = 314 cm²

Three people, A, B and C, share $416 among themselves. A receives $169 and Breceives $156. Find the ratio in which the sum of money is shared.

Answer»

Answer:

Let the TOTAL amount be Rs. p.

Let SHARES of A and B be Rs. x and Rs. y respectively.

C’s share was Rs. 14

we have, x + y + 14 = p —– (1)

From the GIVEN data, x = (p/2) – 4 —– (2)

Remaining amount = p – (p/2 – 4) => p/2 + 4.

y = 1/2(p/2 + 4) + 8 => p/4 + 10 —– (3)

From (1), (2) and (3)

p/2 – 4 + p/4 + 10 + 14 = p

3p/4 + 20 = p

p/4 = 20 => p = Rs. 80..
