A percentage is a proportion of some whole number. There are 2 ways to find percentages. Firstly, you can multiply by a decimal, or you can use a shortcut.

Multiplying with Decimals

You can always rewrite percentages as decimals. To do this move the decimal point 2 digits to the left. This means that 90% becomes 0.90. Then multiply this decimal by the whole number to find the correct percentage.

Shortcut

Because 90% is a multiple of 10%, we can use a shortcut. First off, find 10% of 140. To find 10% of any number, move the decimal 1 digit to the left. This means 10% of 140 is 14.0. Next, 90% is 10% less than 100%. So, subtract 10% from 140 to find 90%.

Answer:

126

Step-by-step explanation:

We need to find 90% of 140.

90% is the same as 0.9 or 9/10.

140 can be written as 14 x 10.

Multiply 14 x 10 with 9/10.

⇒ 14 x 10 x 9/10

[The 10 and 1/10 cancel out by cross multiplication]

⇒ 14 x 9

⇒ 126

Answer:

40

Step-by-step explanation:

50 / 10 = 5

8 * 5 = 40

Both should be divisible by same amount and that is 5.

Answer:

Answer:

-15 is the answer

Step-by-step explanation:

According to the BODMAS (bracket of Division Multiplication Addition Subtraction) rule

=5*10-5*13

=50-65

=-15

Step-by-step explanation:

5a.

10 white squares

15 shaded squares

5b.

a1 = 1 = 2×1 - 1

a2 = a1 + 2×2 - 1 = 2×1 - 1 + 2×2 - 1 = 2×(1+2) - 2

a3 = a2 + 2×3 - 1 = 2×(1+2+3) - 3

...

an = 2×(1+2+...+n) - n = 2×n×(n+1)/2 - n = n²

so,

a350 = 350² = 122,500

figure350 has 122,500 squares.

5c.

a1 = 1

a2 = a1 = 1

a3 = a2 + 5

a4 = a3 = 6

a5 = a4 + 9

a6 = a5 = 15

a7 = a6 + 13

a8 = a7 = 28

...

a(2n) = a(2n - 1)

a(2n - 1) = a(2(n-1) - 1) + 1 + 4(n - 1) = n×1 + 4(0+1+2+...+n-1) =

= n + 4×(n-1)×n/2 = n + 2×(n² - n) = 2n² - n

therefore,

a350 = a349

a349 = a(2×175 - 1) = 2×175² - 175 = 61,075

figure350 has 61,075 shaded squares.

Answer:

5/12

Step-by-step explanation:

"When two dice are thrown, the total number of sample spaces is 36.

Favourable outcomes = {(1,1),(1,2),(1,4),(1,6),(2,3),(2,3),(2,5),(3,2),(3,4),(4,1),(4,3),(5,2),(5,6),(6,1),(6,5)}

Total number of favourable outcomes = 15

Hence, the probability of getting a sum of prime numbers = 15/36 = 5/12."

This was taken from a Byjus post.

Answer: negative 1 over 2

− 1/2

=negative 0.5−0.5

Reason why:

Step 1 of 2: Add.

Add

(negative 2 over 3 − 2/3) + 1 over 6

1/6

= negative 3 over 6 −3/6

Simplify

negative 3 over 6−

3

6

= negative 1 over 2−

1/2

Step 2 of 2: Simplify, sub-step a: Reduce fraction to lowest terms.

Reduce fraction to lowest terms

negative 3 over 6 −3/6

= −( 3 ÷ 3 ) over ( 6 ÷ 3 )

3 ÷ 3 6 ÷ 3 = negative 1 over 2 −1/2

Answer:

-3x(2x+1)(3x-4)

Step-by-step explanation:

Add and subtract the second term to the expression and factor by grouping.

Anser and Explanation:

First, factor out an x to get:

[tex]x(-18x^2 + 15x + 12)[/tex]

Then, factor out a -3:

[tex]-3x(6x^2 - 5x - 4)[/tex]

Finally, factor by grouping:

[tex]-3x(6x^2 + 3x - 8x - 4)[/tex]

[tex]-3x(3x(2x + 1) - 4(2x + 1))[/tex]

[tex]-3x(3x - 4)(2x + 1)[/tex]

so -3x(3x - 4)(2x + 1) is the factored expression.
