How to convert 12/25 to a decimal number.
Step-by-step explanation:
0.48 is the decimal form of 12/25
Answer:
0.48
Step-by-step explanation:
First you have to...
make the denominator to 100
25×4=100
multiply the numerator with that same number
12×4=48
So, it becomes...
48/100
And now you can convert it to a decimal number...
48/100= 0.48
Hope it helps you!!!

Which inequality is equivalent to this one? y-85-2
Answer:
[tex]y-8+2\leq -2+2[/tex]
Step-by-step explanation:
Since you're adding either 8 or 2 to both sides, the inequality sign doesn't change.
So we can eliminate the first and second choice.
Now it's down to the bottom two.
The third choice is adding 2 to the left hand side and then adding 8 to the right hand side. You can't add two different numbers to different sides.
Therefore, the last one must be the correct answer.
The last one is adding two to both sides and have the same inequality sign.

The length of the shorter diagonal of a rhombus is 10 centimeters. Determine the length of the longer diagonal, to the nearest centimeter, if the perimeter
of the rhombus is 52 centimeters.
Length of the longer diagonal
cm
Answer:
24cm
Step-by-step explanation:
Perimeter of a rhombus = 4a
a is the side of the rhombus
52 = 4a
a = 52/4
a = 13cm
If the length of the shorter diagonal of a rhombus is 10 centimeters, then the length of the other diagonal is expressed as;
L = 2 * √a²-(s/2)²
s is the length of the shorter diagonal
Given
a = 13cm and s = 10cm, substitute
L = 2 * √13²-(10/2)²
L = 2*√169-5²
L = 2*√169-25
L = 2*√144
L = 2*12
L = 24cm
Hence the length of the longer diagonal is 24cm

3x+2y=2
2x+2y =-7
Answer:
x= 9
y=-12.5
Step-by-step explanation:
3x+2y = 2×2
2x+2y =-7×3
6x+4y =4
- 6×+6y =-21
-2y =25
y=-12,5
2x+2(-12,5)= -7
2x+-25= -7
2x= -7+25
2x/2=18/2
x= 9
