Answer: 32 over 45 (32/45)
Step-by-step explanation:
4/5 x 8/9 can be separated into two sections, the numerators and the denominators. Multiply them separately...
Numerators: 4 x 8 = 32
Denominators: 5 x 9 = 45
Then bring them back together, the Nermerator on top and the denominator on the bottom.
32/45
The number cannot be simplified further!

Answer:
43.30cm²
Step-by-step explanation:
Use Herons formula
S = (a+b+c)÷2
Where a, b, c is the sides of the triangle
If perimeter is 30cm
Since it's an equilateral triangle, all sides are equal.
Then
Perimeter = 3a = 30
a = 30/3 = 10cm
b = 10cm , c = 10cm
Therefore ,s= (10+10+10)÷2 = 30÷2 = 15cm
From Herons formula
Area = square root of s(s-a)(s-b) (s - c)
Area = sq rt 15(15 - 10)(15 - 10)(15 - 10)
Area = sq rt 15.× 5 × 5 ×5
Area = sq rt 1875
Area = 43.30cm²

Answer:
≈ 43.3 cm²
Step-by-step explanation:
The area (A) of an equilateral triangle is calculated as
A = ( s is the side length )
The 3 sides of an equilateral triangle are congruent, thus
s = 30 ÷ 3 = 10 cm
A = =
= 25
≈ 43.3 cm²

What is rounding up numbers?
There are basically two rules while rounding up numbers
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Non-zero digits are always significant
Zeros between non-zero digits are always significant
Leading zeros are never significant
Trailing zeros are only significant if the number contains a decimal point
Given data ,
Let the number be represented as A
Now , the value of A = 600 tens
There are 60 tens in 600 because 10 x 60 = 600.
To convert from tens to thousands, we need to divide by 100, since there are 100 tens in one thousand.
On rounding , we get
So to find out how many thousands are in 600 tens, we can divide 600 by 100:
600 / 100 = 6
Hence , there are 6 thousands in 600 tens

Step-by-step explanation:
The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.
Answer:
D
Step-by-step explanation:
y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)
That means the equation is y = 50x + 25
