Answer:
1.07m
Step-by-step explanation:
the first step is to convert inches to cm
1in =2.54cm
(42.4in/1in x2.54cm)
42.4in = 107.69cm
then convert cm to m
1cm =0.01m
(107.69cm/1cm x 0.01m)
107.69cm =1.0769m
~1.07m
Answer:
$1.10
Step-by-step explanation:
The cost of one meter of fabric is $1.20.
Given that 1 ft = 0.305 meters
Hence, 1 meter = 
ft = 3.278 ft
So, the cost of 3.278 ft of fabric is $1.20
As Sarah needs 3 feet of fabric for her project, then it will cost 
Dollars (Approximate)

Answer:
x = 25
Step-by-step explanation:
Equiangular triangle is also equilateral triangle.
This means their sides are of equal length.
So, AB = BC = AC
Consider AB = BC
3x - 5 = 2x + 20
3x - 2x = 20 + 5
x = 25
Check:
Length of AB = 3x - 5 = 3(25) - 5 = 75 - 5 = 70
Length of BC = 2x + 20 = 2(25) + 20 = 50 + 20 = 70
Length of AC = 4x - 30 = 4(25) - 30 = 100 - 30 = 70
Step-by-step explanation:
Here, I'll use C for combinations.
There are 15 boys and you need 3 so 15 C 3 ways
There are 30 girls and you need 7 so 30 C 7
and there are 45 total and you need 10 so 45 C 10
The answer is [15 C 3 • 30 C 7] over 45 C 10
so do that on your calculator if you need an actual decimal.
Answer:
y = 3m - 6
Step-by-step explanation:
y = mx + b
b is the point where the line cuts the y axis.
That happens at (0,-6)
So far what you have on this equation is
y = mx - 6
You could use the point that cuts the x axis to find m.
y = 0
x = 2
0 = m*2 - 6 Add 6 to both sides
6 = m*2 - 6 + 6
6 = 2*m Divide by 2
6/2 = 2m/2 Do the division
3 = m
Answer
y = 3m - 6
