find the value of x
a. 2
b. 4
c. 6
d. 8

Answer:

There's an infinite number of possible answers because there might be any multiplication of 3 for boys and any multiplication of 2 for girls. So, for example:

There might be 3 boys and 2 girls.

There might be 6 boys and 4 girls.

There might be 9 boys and 6 girls.

There might be 12 boys and 8 girls.

etc...

In each case the ratio stays the same - 3 : 2.

Of course there probably can't be more than a few dozens of people in one class, but theoretically we can raise the numbers up to infinite.

Answer:

a. 80%

b. £34

c. £340

Step-by-step explanation:

a. We are given that Mrs Trent spent 20% of her weekly wage on food. This means she would have 80% of her weekly wage left with her.

b. 10% of Mrs Trent weekly wage:

If 20% = £68

10% = (10*68)/20 = £34

c. Let x represent weekly wage of Mrs Trent

Given that she spends £68 of x (weekly wage) on food, which is 20% of x.

This means that, 20% of x = £68

Let's find her weekly wage, x:

[tex] \frac{20}{100} * x = 68 [/tex]

[tex] 0.2x = 68 [/tex]

Divide both sides by 0.2

x = 340

Her weekly wage is £340.

Answer:

a) 80%

b) £34

c) £340

Step-by-step explanation:

A -

100% - 20% = 80%

B -

68 = 20%

34 = 10%

c -

34 = 10%

340 = 100%

as you times both sides by 10

Answer:

sin²θ

Step-by-step explanation:

Using the trigonometric identities

sin²x + cos²x = 1 ⇒ cos²x = 1 - sin²x

cotx = [tex]\frac{cosx}{sinx}[/tex]

Given

[tex]\frac{1-sin^20}{cot^20}[/tex]

= [tex]\frac{cos^20}{\frac{cos^20}{sin^20} }[/tex]

= cos²θ × [tex]\frac{sin^20}{cos^20}[/tex] ( cancel the cos²θ )

= sin²θ

Answer:

20 yes

Step-by-step explanation:

3x-6=4x+8

-8-6=4x-3x

-14=x

Answer:

x = -14

Step-by-step explanation:

3(x - 2) = 4x + 8

~Distribute left side

3x - 6 = 4x + 8

~Add 6 to both sides

3x = 4x + 14

~Subtract 4x to both sides

-x = 14

~Divide -1 to both sides

x = -14

Answer:

x² + y² is equal to = (4 / 81)(845m² + 78m + 18)

Step-by-step explanation:

We first need to get the values of x and y, which can be done using a system of equations, substituting one of the two functions into the other:

Given:

y = 2x + 2

3x + 3y = 26m

Then:

3x + 3(2x + 2) = 26m

3x + 6x + 6 = 26m

9x + 6 = 26m

9x = 26m - 6

x = (26m - 6) / 9

Now we can solve for y:

y = 2x + 2

y = 2(26m - 6) / 9 + 2

y = 2(26m - 6) / 9 + 18 / 9

y = (52m - 12 + 18) / 9

y = (52m + 6) / 9

Now we can sum up their squares:

x² + y²

= ((26m - 6) / 9)² + ((52m + 6) / 9)²

= (676m² - 312m + 36) / 81 + (2704m² + 624m + 36) / 81

= (3380m² + 312m + 72) / 81

= (4 / 81)(845m² + 78m + 18)

Answer:

13/20

Step-by-step explanation:

Probability is the ratio of the number of possible outcome to the number of total outcome.

Given that for the past 60 days, on 39 of those days she arrived at work before 8 AM while for the rest of those days she arrived after 8:30 AM, the probability that she will arrive at 8 AM on the next day she goes to work

= 39/60

= 13/20

In decimal, this will be expressed as 0.65 and 65% in percentage.
