Answer:
R17 700
Step-by-step explanation:
Dumsani earns R42 480 per month. He splits his earnings in the ratio 7:5 and then saves the lesser amount. How much does he save?
Step 1
We have ratio 7:5
The sum of the proportion = 7 + 5 = 12
We are told in the above question, that he saves the lesser amount
The lesser ratio = 5
Hence, the amount he saves is calculated as:
5/12 of R42 480
= 5/12 × R42 480
= 5 × 3540
= R17 700
Therefore, he saves R17 700

0-3y=12
Then solve for y
0-3y=12---> y= 12/-3
y=-4

Solve the inequality and enter your solution as an inequality comparing the variable to a number. X-8 < 23
Answer:
x < 31?
Step-by-step explanation:
Given the inequality: x-8 < 23, you must add 8 to 23 to isolate the variable. So...
x - 8 < 23
x < 31

CAN SOMEONE HELP ME ASAP
Answer:
3 minutes
Step-by-step explanation:
To calculate this, you have to multiply 4.5 minutes by 8. This will give you the amount of pages that Wafa will print.
4.5 x 8 = 36 pages
Now that you have the amount of pages, you should divide it by the speed of the Sure-Fire printer. 12 ppm means that 12 pages can be printed in 1 minute.
36/12 = 3
Therefore, it would take 3 minutes if Wafa were to use her brother's Sure-Fire printer.
Answer:
3 minutes
Step-by-step explanation:
Apricot prints 8 pages per minute, the Sure-fire prints 12.
That means Wafa's brother's printer is 1.5 times faster than Wafa's own.
That means his printer can print the document in 4.5min / 1.5 = 3min
Rafael needs to read 3 novels each month.
Let N be the number of novels Rafael needs to read in M months.
Write an equation relating N to M. Then use this equation to find the number of novels Rafael needs to read in 13 months.
Answer:
n×m= number of books read
3×13= 39 books
Step-by-step explanation:
Using substitution for the original equation with m and n, you can find the number of books read by plugging in the numbers in place of the variables.

A triangle has sides with lengths of 5 centimeters, 12 centimeters, and 15 centimeters. Is it a right triangle
Answer:
No
Step-by-step explanation:
You use the Pythagorean Therom and square your legs (5 and 12) and your hypotenuse (14) it would add up to 25+144=196.
This is not true since 144+25 is 169, not 196
Answer:
No, it is not a right triangle.
Step-by-step explanation:
You can determine whether a triangle is a right triangle by using the pythagorean theorem.
a^2 + b^2 = c^2
c will always be the longest side of the triangle, so in this case you need to substitute 5 and 12 in for a and b and see if it simplifies to 15.
5^2 + 12^2 = c^2
25 + 144 = c^2
c^2 = 169
c = 13
C would be 13, not 15, so the triangle is not a right triangle
Hope that helps! :))

Write an equation of the perpendicular bisector of the segment with endpoints M(1,5) and N(7,−1).
PLEASE HELP!!!
Answer:
Step-by-step explanation:
slope of MN=(-1-5)/(7-1)=-6/6=-1
slope of line ⊥ to given line=-1/(-1)=1
To find mid point of M and N
[tex]x=\frac{1+7}{2} =4\\y=\frac{5+(-1)}{2} =2[/tex]
eq. of perpendicular bisector is
y-2=1(x-4)
y=x-4+2
or y=x-2
