Janie receives R150 pocket money per month. In the new year his mother increase his pocket money in the ratio 6:5. Calculate Janies adjusted monthly pocket money?​

Answers

Answer:

Janies' monthly pocket money is $180.

Step-by-step explanation:

Janies' adjusted monthly pocket money:

Initial pocket money = $150

Ratio of new pocket money = 6:5

Let his new pocket money be represented by x,

x:$150 = 6:5

$150 x 6 = x (5)

$900 = 5x

x = [tex]\frac{900}{5}[/tex]

x = $180

Therefore, Janies' monthly pocket money is $180.

. Solve the inequality. q + 12 – 2(q – 22) > 0 q > –32 q > 56 q < –32 q < 56

Answers

Given:

The inequality is

[tex]q+12-2(q-22)>0[/tex]

To find:

The solution of the given inequality.

Solution:

We have,

[tex]q+12-2(q-22)>0[/tex]

It can be written as:

[tex]q+12-2q+44>0[/tex]

[tex](q-2q)+(12+44)>0[/tex]

[tex]-q+56>0[/tex]

Subtract 56 from both side.

[tex]-q>-56[/tex]

Multiply both sides by -1 and change the inequality sign.

[tex]q<56[/tex]

Therefore, the correct option is D.

Answer:

D:   q < 56

Brandon is 9 years older than Ronda. In four years, the sum of their ages will be 91. How old
they now?
I need help step by step solution please!!!!

Answers

Answer:

           Ronda is 37 and Brandon is 46

Step-by-step explanation:

x     - the age of Ronda

x + 9    - the age of Brandon

x + 4     - the age of Ronda in 4 years

x + 9 + 4    - the age of Brandon in 4 years

x + 4 + x + 9 + 4    - the sum of their ages in 4 years

x + 4 + x + 9 + 4 = 91

2x + 17 = 91                  {subtract 17 from both sides}

2x = 74                   {divide both sides by 2}

 x = 37

x + 9 = 37 + 9 = 46

Express the ratio 4:7 in the form n:1

Answers

The ratio 4:7 in the form n:1 is [tex]\frac{4}{7} : 1[/tex] .

What is unit fraction?

A unit fraction is a rational number written as a fraction where the numerator is one and the denominator is a positive integer. A unit fraction is therefore the reciprocal of a positive integer, 1/n. Examples are 1/1, 1/2, 1/3, 1/4, 1/5, etc.

According to the question

The ratio 4:7  in the form n:1

i.e

[tex]\frac{4}{7} = \frac{n}{1}[/tex]

n = [tex]\frac{4}{7}[/tex]

Now, the unit fraction

The ratio is

= [tex]\frac{4}{7} : 1[/tex]

Hence, the ratio 4:7 in the form n:1 is [tex]\frac{4}{7} : 1[/tex] .

The graph of which line intersects the graph of y + 10 = -5(x - 1) in only one point?

Answers

A

First, I’m going to the line is question into slope intercept form.
y + 10 = -5x + 5
y = -5x + 5 -10
y = -5x -5
y + 10 = -5 (x - 1) becomes y = -5x -5 in slope intercept form. I will call this line ‘line 1’

A becomes y = 5x -15 in slope intercept form
B becomes y = -5x + 25 in slope intercept form
C becomes y = -5x -5 in slope intercept form
D becomes y = -5x + 10 in slope intercept form

C is the same line as line 1. Any point that is on line 1 is also on line C, so C cannot be it.

Notice that line B and D have the same slope but different y-intercepts as line 1. That means these lines are parallel (not the same line though - different y intercepts) to line 1, so they will never intercept.

Line A has a different slope vs line 1, so they will eventually intersect only once

Angle RXU is Angle 3, so Angle 3 = 52°

Since the angle of a line adds to 180°,

and we are finding Angle SXU or 2,

we can say...

Angle SXU = 180° - 52°

Angle SXU = 128°
