saveliy_v [14]

Answer:

a=5q^ {2}

b=r^{2}s

Step-by-step explanation:

Here 125q^{6} is like the a^{3} in the general formula.

So we can write 125q^{6} as:

(5q^ {2} )^{3}

We can also write r^{6} s^{3} as:

(r^{2}s)^{2}

Therefore:

a³=(5q^ {2} )^{3}

b²=(r^{2}s)^{2}

I need help with some tutorverse questions, thanks!
Aloiza [94]

Answer:

11. c

12. c

Step-by-step explanation:

11. Since Angle RST = 60 degrees, Angle RTS = 60 degrees.

Triangle STU is a right triangle, so Angle STU and Angle SUT are both 45 degrees.

Angle RTS + Angle STU + Angle UTQ = 180 degrees

60 + 45 + Angle UTQ = 180

Angle UTQ = 180 - 105

                   = 75 degrees

12. Using the corresponding angles theorem, x = 45 degrees and y = 35 degrees.

x + y

45 + 35

The age of a father is two less than seven times the age of his son in two years the sum of their ages will be 57 if the son's p
ASHA 777 [7]

Answer:

f = 7s -2

f  + s =53

Step-by-step explanation:

Given

Let

f = Father's age

s = Son's age

We'll solve this question, while reading through the instructions

From the first statement;

f is 2 less than 7 times s.

This means

f = 7s -2

In two years time, the father will be f +2 and the son will be s + 2

So, their sum is:

(f+2) + (s + 2) = 57

f + 2 + s + 2 =57

Collect like terns

f  + s =57-2-2

f  + s =53

So, the equations are:

f = 7s -2

f  + s =53

Lightbulb consumes 12,600 Watt- hours in 3 days and 12 hours. How many watt- hours does it consume per day
sladkih [1.3K]
3 days = 72 hours + 12 hours = 84 hours

12600 watt hours / 84 hours

= 150 watt hours / 1 hour

It’s asking how many watt hours consumed per day. We know 150 watt hours per hour so multiply that by 24 because 24 hours in a day

= 3600 watt hours per day

The equation of the line is y = 1/6x + 3

<h3>How to determine the equation?</h3>

The equation of the line is given as:

y = -6x - 14

The above equation has a slope of

m = -6

Let the slope of the other line be n.

So, we have:

n =-1/m ---- slope condition for perpendicular lines

So, we have:

n = 1/6

The equation is then calculated as:

y = n(x - x1) + y1

Where

(x1, y1) = (12,5)

This gives

y = 1/6(x - 12) + 5

Expand

y = 1/6x - 2 + 5

Evaluate the sum

y = 1/6x + 3

Hence, the equation of the line is y = 1/6x + 3
